If 1+1 =2 than what does 3x+5x equal
Answer:
If 1 + 1 = 2, then we can say that 1 = 2 - 1. Now, if we have 3x + 5x, we can factor out the common term of x to get: 3x + 5x = (3 + 5)x = 8x So, 3x + 5x = 8x.
g a company has a customer retention rate of 55% per year. it is testing a new customer experience plan. what is the minimum number of customers that need to be included in the test to determine if the new plan has more than a 10 percentage point effect on customer retention, with 90% confidence? use the normal approximation. g g
The minimum number of customers that need to be included in the test to determine if the new plan has more than a 10 percentage point effect on customer retention, with 90% confidence is at least 192 customers.
To determine the minimum sample size needed to test if the new plan has more than a 10 percentage point effect on customer retention, we can use the following formula:
n = [(Zα/2 + Zβ)² × (p1 × (1-p1) + p2 × (1-p2))] / (p1 - p2)²
where:
n is the sample size needed
Zα/2 is the z-score corresponding to the desired confidence level (90% confidence corresponds to a z-score of 1.645)
Zβ is the z-score corresponding to the desired power (we'll use a power of 80%, which corresponds to a z-score of 0.84)
p1 is the retention rate under the current plan (55%)
p2 is the retention rate under the new plan (55% + 10% = 65%)
Plugging in the values, we get:
n = [(1.645 + 0.84)² × (0.55 × 0.45 + 0.65 × 0.35)] / (0.10)²
n = 191.34
Rounding up to the nearest whole number, we get a minimum sample size of 192.
Therefore, the company needs to include at least 192 customers in the test to determine if the new plan has more than a 10 percentage point effect on customer retention, with 90% confidence.

Compare the data and use the correct measure of variability to determine which bus is the most consistent. Explain your answer.
Bus 47, with an IQR of 8
Bus 14, with an IQR of 6
Bus 47, with a range of 8
Bus 14, with a range of 6
The correct option regarding which bus has the least spread among the travel times is,
⇒ Bus 14, with an IQR of 6.
Now, First we consider the dot plot, which shows the number of times that each observation appears in the data-set.
Then we consider the interquartile range, which gives the difference between the third quartile and the first quartile of the data-set.
The interquartile range is a better measure of spread compared to the range of a data-set, as it does not consider outliers.
For groups of 15 students, we have that:
The first half is composed by the first seven students, hence the first quartile is the fourth dot, which is the median of the first half.
The second half is composed by the last seven students, hence the first quartile is the eleventh dot, which is the median of the first half.
The quartiles for Bus 14 are given as follows:
Q1 = 12.
Q3 = 18.
Hence the IQR is of:
IQR = Q3 - Q1
= 18 - 12
= 6.
The quartiles for Bus 18 are given as follows:
Q1 = 9.
Q3 = 16.
Hence the IQR is of:
IQR = Q3 - Q1
= 16 - 9
= 7.
Hence, Bus 14 is the more consistent bus, due to the lower IQR.

Sophie deposited money into an account in which interest is compounded semiannually at a rate of 4.2%. She made no other deposits or withdrawals and the total amount in her account after 9 years was $24,575.22. How much did she deposit? Round answer to nearest whole number.
Sophie deposited approximately $16,516.
What are whole numbers?The digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and so forth are known as whole numbers. They are the figures we use to measure things, such as the quantity of pencils in a box or apples in a basket. In computations like addition, subtraction, multiplication, and division, whole numbers are also employed.
Let's call the amount Sophie deposited "P". After 9 years, the investment would have gone through 18 compounding periods (2 per year for 9 years).
The formula for calculating the future value (FV) of an investment with compound interest is:
[tex]FV = P(1 + r/n)^{(nt)[/tex]
where:
P = the principal (the initial amount invested)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
In this case, we have:
P = unknown (what we're trying to find)
r = 4.2% = 0.042
n = 2 (since the interest is compounded semiannually, or twice a year)
t = 9
So the formula becomes:
[tex]24,575.22 = P(1 + 0.042/2)^{(2*9)[/tex]
Simplifying the right side of the equation:
24,575.22 = P(1.021)¹⁸
24,575.22 = 1.485P
Dividing both sides by 1.485:
P ≈ $16,516
Therefore, Sophie deposited approximately $16,516.

assume that the weights are normally distributed. the vacuum company natureabhors claims their vacuums are on average lighter than the market average. we sample 31 bagless upright vacuum cleaners from nature abhors and get an average of 19.33. can we show at the 5% significance level that their average is below 19.64?
At the 5% significance level, we can reject the null hypothesis and conclude that there is sufficient evidence to suggest that the average weight of the vacuums from Nature Abhors is less than 19.64 pounds.
To answer this question, we can use a one-sample t-test, assuming that the population of weights is normally distributed. The null hypothesis is that the true mean weight of the vacuums from Nature Abhors is 19.64 pounds, while the alternative hypothesis is that it is less than 19.64 pounds.
We can calculate the t-statistic using the formula
t = (X - μ) / (s / sqrt(n))
where X is the sample mean (19.33), μ is the hypothesized population mean (19.64), s is the sample standard deviation, and n is the sample size (31).
Since we don't know the population standard deviation, we can estimate it using the sample standard deviation. We calculate the sample standard deviation as follows
s = sqrt(sum((xi - X)^2) / (n - 1))
where xi is the weight of the i-th vacuum in the sample. We assume that the weights are normally distributed, so we can use the t-distribution with (n-1) degrees of freedom to calculate the p-value.
Using a t-table or calculator, we can find the critical t-value for a one-tailed test at the 5% significance level with 30 degrees of freedom to be -1.699.
Plugging in the numbers, we get
t = (19.33 - 19.64) / (s / sqrt(31))
s = sqrt(sum((xi - X)^2) / (n - 1)) = 0.714
t = (-0.31) / (0.714 / sqrt(31)) = -1.84
Since the calculated t-value (-1.84) is less than the critical t-value (-1.699), we can reject the null hypothesis at the 5% significance level. Therefore, we can conclude that there is sufficient evidence to suggest that the average weight of the vacuums from Nature Abhors is less than 19.64 pounds.

Jody is feeding her dog from a 10-pound bag. The dog goes through 1 pounds of food
each week.
Enter, in decimal form, how many pounds of food are left after 3 weeks.
After 3 weeks, the dog consumed 3 pounds of food, leaving 7 pounds of food left. Subtracting the amount of food consumed from the initial amount, 10 pounds - 3 pounds = 7 pounds.
How many pounds of food are left after 3 weeks?After 3 weeks, the dog would have consumed 3 pounds of food (1 pound per week x 3 weeks = 3 pounds).
To find out how many pounds of food are left, we can subtract the amount of food consumed from the initial amount:
10 pounds - 3 pounds = 7 pounds
So there are 7 pounds of food left after 3 weeks.
Expressed in decimal form, it would be 7.0 pounds.
What is decimal form?The base-10 numbering system, which employs ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) to represent all conceivable numerical values, is used to express numbers in decimal form.

2 random samples of 16 paper towels from 2 different brands were tested for absorbency. the mean amount of water absorbed for brand a was 15.63 ml. with a standard deviation of 3.12 ml. for brand b the mean was 14 ml. with a standard deviation of 2.53 ml. a) find a 95% confidence interval for the mean difference in the amount absorbed. state what df you used as well. b) does this interval suggest that there is a significant difference between brands in the amount absorbed?
The 95% confidence interval for the mean difference in the amount absorbed is (0.01, 3.25) ml, with a df of 28. Yes, the interval does not contain zero, suggesting that there is a significant difference between the two brands in the amount absorbed.
To find the 95% confidence interval for the mean difference in the amount absorbed, we can use the formula:
CI = (x1 - x2) ± tα/2 * SE
where x1 - x2 is the difference in means, tα/2 is the critical value from the t-distribution table for a 95% confidence interval with degrees of freedom (df) = 30 - 2 = 28 (assuming equal variances), and SE is the standard error of the difference in means:
SE = sqrt[(s1^2/n1) + (s2^2/n2)]
Plugging in the values, we get:
x1 - x2 = 15.63 - 14 = 1.63
s1 = 3.12, n1 = 16
s2 = 2.53, n2 = 16
SE = sqrt[(3.12^2/16) + (2.53^2/16)] = 0.974
tα/2 for df = 28 and α = 0.05 is 2.048.
CI = (1.63) ± (2.048 * 0.974) = (0.01, 3.25)
Therefore, the 95% confidence interval for the mean difference in the amount absorbed is (0.01, 3.25), with df = 28.
This interval suggests that there is a significant difference between brands in the amount absorbed, since the interval does not include 0. This means that we can reject the null hypothesis that the means are equal at a 5% significance level and conclude that the mean amount of water absorbed for brand A is significantly greater than brand B.

What is a ratio?The simple procedure percentage "a / b," once "b" could be a larger than zero, is used to find a group of numbers both "a" and " that appear to be equal. Two ratios are combined to form a ratio. If there were only one man and three ladies, the ratio would be 1:1. In the group, there are 3/4 women and 1/4 males. A division between things, a number, or a particular physical component of a component can all be described as having "parts."
Here,
Let's express the quantity of pumpkin cans as 5x (where x is some multiplier) and the quantity of green bean cans as 2x.
Given that there are 126 cans in total, we can construct the following equation:
=> 5x + 2x = 126
Combining related words gives us:
=>7x = 126
When we multiply both parts by 7, we get:
=> x = 18
John therefore requires 2 cans of green beans and 5 cans of pumpkin:
=> 5x = 5(18) = 90 pumpkin cans
=> 2x = 2(18) = 36 green bean cans.
So, for his exhibit, John needs to use 36 cans of green beans.

Write the equation of a line that is perpendicular to the line y = 1/2x + 1 and goes through 6 on the x axis
Answer:
y = - 2x + 12
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{2}[/tex] x + 1 ← is in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2 , then
y = - 2x + c ← is the partial equation
to find c substitute (6, 0 ) , the point it crosses on the x- axis into the partial equation.
0 = - 2(6) + c = - 12 + c ( add 12 to both sides )
12 = c
y = - 2x + 12 ← equation of perpendicular line
GIVEN EQUATION IS y = 1/2x + 1
This method teach us in order to write this equation in perpendicular form we will change the coefficient of Y axis in to X axis and X axis into Y axis by a negative of sign WITH ONE of them and rePlace constant term as KNOW PERPENDICULAR EQUATION CAN BE WRITTEN AS
y = -2x + kSince the line passes through the point (6,0) on the x-axis, we can substitute these values into the equation to solve for k:
0 = -2(6) + k0 = -12 + kk = 12Therefore, the equation of the line that is perpendicular to y = 1/2x + 1 and passes through the point (6,0) is y = -2x + 12.The diagram shows a prism.

3120 different types of colorings are possible . Thus, Option C is the correct option. There are 3 cases involved
If there are no similar color pairs then it comes down to simple permutations. Then 6 different types of colors in 5 different spots.6! = 720 cases
No rotation is necessary because all permutation are already accounted for.
If there is one color pair then, consideration of 6 possibilities for the pair is essential 5 for the 3rd vertex, 4 for the 4th vertex, 3 for the 5th vertex6 × 5 × 4 × 3 = 360
There are 5 different locations where the pair can be present.
360 × 5 = 1800 one pairs is possible
If there are two color pair still we have to account for 6 possibilities for the first pair then 5 possibilities for the next pair and 4 possibilities for the last pair.6 × 5 × 4 = 120
There are 5 rotations in the pentagon so the total number of possibilities is
120 × 5 = 600 two pairs are possible
now, we add the 3 cases to find the total number of possibilities

the pie chart shows the age distribution in a village of 120 people. how many villagers are over 60.And what percentage of villagers are under 25
We can say that approximately 48 villagers (40% of 120) are under the age of 25. This means that just under half of the population in this village is under the age of 25.
According to the pie chart, we can see that the village of 120 people has 20% of its population over the age of 60. To determine the exact number of villagers over 60, we can multiply the total population by the percentage of people over 60:
120 x 20% = 24
So there are 24 villagers over the age of 60 in this village.
As for the percentage of villagers under the age of 25, we can see from the pie chart that 40% of the population falls into this category. However, it is important to note that the question mentions a village of 120 people, while the percentage given in the chart may not reflect this exact number. Therefore, we cannot determine the exact number of villagers under the age of 25 without additional information.

The probability of running out of anchovies before the evening is over is approximately 0.058, or 5.8%. We must presume that the number of pizzas ordered with anchovies follows a binomial distribution with parameters n = 60 (the total number of pizzas) and p = 0.08 in order to answer this issue using the normal approximation for the binomial distribution. (the probability of ordering anchovies on a pizza).
The standard deviation of this binomial distribution is given by = sqrt(np(1-p)) = sqrt(60 x 0.08 x 0.92) = 2.03, and the mean is given by = np = 60 x 0.08 = 4.8.
Now, we need to determine the likelihood that we will need to prepare more than eight anchovy-topped pies before the evening is through in order to determine the likelihood that we will run out of anchovies. (since we only have enough anchovies for 8 pizzas).
This is equivalent to finding the probability that the number of pizzas with anchovies is greater than 8, or P(X > 8), where X is the number of pizzas with anchovies.
To use the normal approximation for the binomial distribution, we need to standardize the variable X using the standard normal distribution. This gives us:
z = (X - μ) / σ = (8 - 4.8) / 2.03 = 1.57
Using a standard normal table or calculator, we can find the probability that z is greater than 1.57, which is approximately 0.058. Therefore, the probability of running out of anchovies before the evening is over is approximately 0.058, or 5.8%.

One angle of a right triangle measures 85°. What is the measure of the other acute angle?
Answer:
5°
Step-by-step explanation:
The three angles of a triangle add up to 180° (every triangle, always) Since this triangle is a right triangle, one of the angles is a right angle, 90°.
Another angle is given, 85°.
x + 85° + 90° = 180°
x + 175° = 180°
x = 5°
To do this question using mental math, if one angle is 90° the other two angles must add up to 90° (thats the total of 180°) One angle is 85° then the other is 5°

Square root of x equals negative seven
the equation √x = -7 has no real solutions.
Why it is?
There is no real number x that satisfies the equation √x = -7.
The square root of a non-negative real number is always non-negative. Therefore, √x is non-negative for all real numbers x, including x = 0. However, -7 is negative, so the equation √x = -7 has no real solutions.
An equation is a statement that asserts the equality of two mathematical expressions. It generally consists of two sides, left-hand side (LHS) and right-hand side (RHS), which are separated by an equal sign (=). An equation is true when both the LHS and RHS represent the same value or expression.

a lizard is stuck in a 12 ft deep hole. every day it crawls 4 ft up the side of the hole. every night it slides down 2 ft. how long will it take the lizard to get out of the hole? dm me answer
Using the time formula, it will take the lizard 6days to reach the top of the well.
What is the time formula?The time formula, using distance and speed, is as follows:
Time = Distance ÷ Speed
The depth of the well and the lizard's position = 12 feet
Daily crawling-up rate = 4 feet
Daily crawling down rate = 2 feet
Difference between crawling up and slipping down rates = 2 foot per day ( 4- 2)
Therefore, the lizard's net average crawling up speed or rate = 2 foot per day
Time (in days) = Distance/Average Rate
12/2 = 6 days
Thus, for the lizard to reach the top of the well, it will take 6 days.

THANK YOU
Answer:7,6,5
Step-by-step explanation:
So this is how I did it
So the theorem is
a+b>c
a+c>b
b+c>a
---
Let's now substitute A= 6 and B =2 so It'll look something like
6+2> C
6+C> 2
2+C>6
From there I added like terms
8>C
4<C
2<C
Then from there I noticed the numbers 5,6,7 are the the only whole numbers between 4 and 8. So that's what I'm put as my answer.
Draw a line tangent to the circle whose equation is (x-2)² + y² = 20 at the point
(0, 4). Write an equation for this tangent line.
The equation of the tangent line to the circle at the point (0, 4) is y = 1/2x + 4
How to find the equation of the tangent lineTo find the equation of the tangent line to the circle at the point (0,4), we need to first find the slope of the tangent line at that point.
The slope of a tangent line to a circle at a given point is equal to the negative reciprocal of the slope of the radius that passes through that point.
The center of the circle is at the point (2, 0), and the radius passing through the point (0, 4) has a slope of:
m = (0 - 4)/(2 - 0) = -2
Therefore, the slope of the tangent line at (0, 4) is:
m' = -1/m = -1/(-2) = 1/2
Now that we have the slope of the tangent line, we can use the point-slope form of a line to find the equation of the tangent line.
The point-slope form of a line is:
y - y1 = m(x - x1)
where m is the slope of the line, and (x1, y1) is a point on the line.
Using (0,4) as the point on the line and 1/2 as the slope, we get:
y - 4 = 1/2(x - 0)
Simplifying, we get:
y = 1/2x + 4
