A x + y = 5 1 + -4 = -3 Nope
B.X + y = 5 1 + -4 = -3 Nope same as A unless X is somehow not equal to x,
C. xy = 5 1(-4) = -4 Nope and does not even qualify as a line.
D. x - y = .5 1 - (-4) = 5 Nope unless you have a typo adding an unwanted decimal point

yards.
Answer:
smaller, divide, 12, and 39 yards
Step-by-step explanation:
An inch is smaller than a yard, so multiply the number of inches by 3 to find the number of yards.
What is a unit conversion?Unit conversion is the process of converting a measurement from one unit of measurement to another equivalent unit of measurement. For example, converting a measurement from meters to centimeters, or from pounds to kilograms.
An inch is smaller than a yard, so multiply the number of inches by 3 to find the number of yards.
Unit conversion is important in many fields, including science, engineering, construction, and even everyday life. For example, in science and engineering, it is common to work with different units of measurement, and converting between them is essential for accurate calculations and analysis.
Therefore, 468 inches is equal to 13 yards.

Round 803.137 to the nearest hundredths place.
Answer:
803.14
Step-by-step explanation:
The number in the hundredths place of the original question is the 3 after the decimal place. The number next to it is a 7, which is higher than 5 so that means you will round up. The 3 then becomes 4 and you drop the 7 completely.
Answer:
803.14
Step-by-step explanation:
Using the distributive property, an expression equivalent to 48 + 30 is
5 (6 + 8).
(6) (8) + (3) (10).
(3) (16) + (6) (5).
6 (8 + 5).
Answer:
d. 6(8+5)
Step-by-step explanation:
First you distribute the 6 to the 8 which gets you 48 and then you distribute the 6 to the 5 to get 30
so you would get 48+30
therefore, d is true
Answer: (6) (8) + (3) (10) and (3) (16) + (6) (5) and 6 (8 + 5) all of them is the same answer as 48+30=78

A worldwide organization of academics claims that the mean IQ score of its members is 118, with a standard deviation of 17. A randomly selected group of 40 members of this organization is tested, and the results reveal that the mean IQ score in this sample is 115.8. If the organization's claim is correct, what is the probability of having a sample mean of 115.8 or less for a random sample of this size
Answer:
0.2061 = 20.61% probability of having a sample mean of 115.8 or less for a random sample of this size
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
A worldwide organization of academics claims that the mean IQ score of its members is 118, with a standard deviation of 17.
This means that [tex]\mu = 118, \sigma = 17[/tex]
A randomly selected group of 40 members
This means that [tex]n = 40, s = \frac{17}{\sqrt{40}} = 2.6879[/tex]
What is the probability of having a sample mean of 115.8 or less for a random sample of this size?
This is the pvalue of Z when X = 115.8.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{115.8 - 118}{2.6879}[/tex]
[tex]Z = -0.82[/tex]
[tex]Z = -0.82[/tex] has a pvalue of 0.2061
0.2061 = 20.61% probability of having a sample mean of 115.8 or less for a random sample of this size

The seventh grade class is putting on a talent show to raise money for a class trip. It costs $500 to rent the banquet hall they are planning on using. If they charge $15 per ticket, how many tickets do they need to sell in order to raise at least $1000?
Part A
The variable in this problem will represent the number of:
A- students
B- tickets
C- parents
D- money
Part B
Choose the correct inequality to represent the story problem:
A- 15x+500=1000
B- 15x-500≥1000
C- 15x+1000≥500
D- 15x-500≤1000
Part C
How many tickets do they need to sell? (Write your answer as an inequality)
Answer:
B-Tickets
B-15x-500≥1000
C-x≥100
Step-by-step explanation:
X is the variable because you need to find how many tickets need to be sold
The answer is B because they need to raise $1000 or more
15x-500≥1000 (add 500 to both sides)
15x≥1500
x≥100
Bianca bought a pack of rechargeable batteries for
$9.99. If the sales tax on the batteries is 3% and Bianca
pays with $11 cash, how much change will she get back?
Answer:
$0.71
Step-by-step explanation:
Find the cost with sales tax
9.99(1.03)
= 10.29
Subtract this from 11
11 - 10.29
= 0.71
So, Bianca will get $0.71 back in change
Answer: 0.71 cents
Step-by-step explanation:
9.99x0.03=0.2997
9.99+0.2997=10.2897 rounds to 10.29
11-10.29=0.71

Answer:
A. y = -x + 8
Step-by-step explanation:
y = mx + c
m = [tex]\frac{y2 - y1}{x2 - x1}[/tex] = [tex]\frac{0 - 8}{8 - 0}[/tex] = -1
c = 8
=> The equation will be y = -1x + 8 or y = -x + 8.
Avocado Pickers are paid as shown below. What would be the gross
earnings for a worker that picks 1,108 avocados?
1 - 500 Avocados $0.10 each
501 - 700 Avocados $0.14 each
Over 700 Avocados $0.18 each
Answer:
The avocado picker earned $151.44.
Step-by-step explanation:
Given that avocado pickers are paid $ 0.10 if they collect from 1 to 500 avocados, $ 0.14 if they collect from 500 to 700 and $ 0.18 if they collect more than 700, to determine what would be the gross earnings for a worker that picks 1,108 avocados, the following calculation must be done:
1,108 - 700 = 408
700 - 500 = 200
500 x 0.10 + 200 x 0.14 + 408 x 0.18 = X
50 + 28 + 73.44 = X
151.44 = X
Therefore, the avocado picker earned $151.44.

2x + y =8 and 4x -2y = 6
Answer:
x=1.25 and y=-5.5
Step-by-step explanation:
2x+y=-8, 2x=-y-8 or 4x=-2y-16. Plug this value in the second equation, we have - 2y-16-2y=6, y=-5.5. Plugging this in any equation we have, x=1.25

C. The mode of the number of miles Ian skated in July is less than the mode of the number of miles Ian skated in August.
Step-by-step explanation:
A. is not correct because the least amount he skated in July was 1 which is not greater than the least amount In August, 5
B. is not correct because the median number for July was 8 which is not greater than the median of August, 10
C. is correct because 8 is the most common number in July which is less than 10, the most common number in August.
D. is not correct because the range in July is 14 (15-1=14) which is not less than the range in August, 8 (13-5=8)

Line m passes through the point (1, 2) and has a slope of 2/5 What is the equation of line m in standard form?
Answer:
5y - 2x = 8
Step-by-step explanation:
First off we have to find the y-intercept with : b = y-mx
[tex]b=2-(\frac{2}{5})(1)[/tex]
[tex]b=\frac{10}{5}-\frac{2}{5}[/tex]
[tex]b=\frac{8}{5}[/tex]
now we have the point slope form
[tex]y=\frac{2}{5}x+\frac{8}{5}[/tex]
Multiply both sides by 5
[tex]5y=2x+8[/tex]
Subtract 2x from both sides
[tex]5y-2x=8[/tex]
