Ron is a huge golfer and he is interested in purchasing a new brand of golf balls that claim to extend his driving
range. Ron sets up an experiment where he will test these new golf balls against the current golf balls he uses to
see if his driving distance had increased. He will hit an SRS of 30 new golf balls and record the average range
and then will hit an SRS of 30 current golf balls and record the average range. He will then compare the
averages to see if there is a difference between the two true distances.
11) What type of study is being conducted by Ron and, of the following, which is the appropriate t-
interval for inference?
(A) A completely randomized design and a t-interval for a difference between means for independent samples

12) the appropriate t-statistic is (C) 1.98.
13) option (c)
What is the central limit theorem?The central limit theorem is a principle in probability theory that states that the distribution of sample means will eventually approximate a normal distribution as the sample size becomes larger.
11) The type of study being conducted by Ron is a completely randomized design, where he randomly assigns the two types of golf balls (new and current) to two separate groups and then compares the mean driving distances between the two groups.
The appropriate t-interval for inference is (A) a t-interval for a difference between means for independent samples.
12) To test the hypothesis of whether there is a significant difference in mean driving distance between the new golf balls and the old golf balls, we need to calculate the appropriate t-statistic.
The formula for the t-statistic for a difference between means for independent samples is:
[tex]t = (x_1 - x_2) / [s1^2/n1 + s_2^2/n_2]^{0.5}[/tex]
where x1 and x2 are the sample means, s1 and s2 are the sample standard deviations, and n1 and n2 are the sample sizes for the two groups.
Using the given data, we have:
x1 = 203.5 yards, x2 = 197.4 yards
s1 = 5.6 yards, s2 = 10.3 yards
n1 = n2 = 30
Substituting these values into the formula, we get:
[tex]t = (203.5 - 197.4) / [(5.6)^2/30 + 10.3^2/30]^{0.5} = 1.98[/tex]
Therefore, the appropriate t-statistic is (C) 1.98.
13) The correct statement about the study being conducted by Ron is (C) The central limit theorem tells us that the sampling distribution of driving distance for each of the individual samples of balls will be approximately normal.
Hence, The answers to the question:
11) (A) a t-interval for a difference between means for independent samples.

The family likes peaches and other fruits. The local farmer’s market is selling fresh peaches at a discounted price. If the farmer’s market sold 35% of its produce and has 260 peaches remaining, how many peaches did it originally have on hand? Show all your work and explain how you used equivalent ratios to solve the problem.
The farmer's market originally had 400 peaches on hand.
What is an equation?
An equation is a mathematical statement that shows that two expressions are equal. It typically consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and radicals.
Let's use x to represent the original number of peaches the farmer's market had on hand.
We know that the farmer's market sold 35% of its produce, which means it sold 0.35x peaches. The remaining number of peaches can be calculated by subtracting the number of peaches sold from the original number of peaches:
remaining peaches = x - 0.35x
We also know that there are 260 peaches remaining, so we can set up an equation:
260 = x - 0.35x
Simplifying this equation, we can combine like terms:
260 = 0.65x
To solve for x, we need to isolate the variable by dividing both sides by 0.65:
x = 260 / 0.65
x = 400
Therefore, the farmer's market originally had 400 peaches on hand.
To explain how we used equivalent ratios, we used the fact that the farmer's market sold 35% of its produce. This can be represented as a ratio of 35/100 or 0.35. We then used this ratio to find the number of peaches sold, which is 0.35x. We also used the fact that the remaining peaches are the original peaches minus the peaches sold, or x - 0.35x. Finally, we set up an equation using the remaining peaches and solved for x to find the original number of peaches.
Hence, the farmer's market originally had 400 peaches on hand.

Your parents are buying a house for $187,500. They have a good credit rating, are making a 20% down payment, and expect to pay $1,575/month. The interest rate for the mortgage is 4.65%. What must their realized income be before each month?
If your parents are buying a house for $187,500. their realized income be before each month is $5250.
How to find the realized income?Loan amount = $187,500 - (187,500 * 20%)
Loan amount = $ 150,000
Monthly rate = 4.65% / 12 = 0.3875%
Interest rate for the first month is:
Interest rate = $ 150,000 * 0.3875% = $ 581.25.
Loan repayment =$ 1,575 - $ 581.25 = $ 993.75.
Amount parents owe = $ 150,000 - $ 993.75 = $149,006.25
Second month Loan = $ 1,575 - ($149,006.25 * 0.3875%) = $ 997.60
Second month ending amount owe = ( $149,006.25 - $997.60)
Second month ending amount owe = $ 148,008.65
A monthly loan payment that is not more than 30% of monthly income will be used to find the realized income.
Realized income = $ 1,575/30% = $ 5,250
Therefore the realized income is $5250

What is the probability that at least one of a pair of fair 6-sided dice shows the number 2, given that the sum of the dice is 4?
Therefore, the probability that at least one of the dice shows the number 2, given that the sum of the dice is 4, is 1 - (1/5) = 4/5, or 0.8, which is the probability that at least one of the two dice is a 2.
What are instances and probability?It is founded on the likelihood that something will occur. The rationale for probability is the central tenet of theoretical probability. For instance, there is a 12% chance that a coin will land on its head when flipped.
There are five possible ways to obtain a sum of 4 with two 6-sided dice: {(1,3),(2,2),(3,1),(2,1),(1,2)}.
Out of these five possible outcomes, there is only one outcome where neither of the dice show a 2, which is {(1,3)}.
Therefore, the probability that at least one of the dice shows the number 2, given that the sum of the dice is 4, is 1 - (1/5) = 4/5, or 0.8, which is the probability that at least one of the two dice is a 2.

The Silver Spur is a popular local hiking trail. The start of the trail is 179ft above sea level. The table shows the amount of elevation gain between the previous point of interest on the trail and the current one. (The elevation gain shown for the Old Cabin is the elevation gained between the start of the trail and the Old Cabin.) Point of Interest Elevation gain (in ft) Old Cabin −32.78 Ruby Falls 8634 Thunder Gorge −14725 High Point Vista 346.47 What is a hiker’s elevation above sea level (in feet) upon reaching High Point Vista?
Answer:
Step-by-step explanation:
To find the hiker's elevation above sea level upon reaching High Point Vista, we need to add up the elevation gain from the start of the trail to High Point Vista. We can use the table to do this:
Elevation gain from start to Old Cabin: -32.78 ft (negative because the hiker loses elevation)
Elevation gain from Old Cabin to Ruby Falls: 8634 ft
Elevation gain from Ruby Falls to Thunder Gorge: -14725 ft (negative because the hiker loses elevation)
Elevation gain from Thunder Gorge to High Point Vista: 346.47 ft
To find the hiker's elevation above sea level at High Point Vista, we add up these elevation gains:
179 ft (start) - 32.78 ft + 8634 ft - 14725 ft + 346.47 ft = -5668.31 ft
The negative value means that the hiker is below sea level at High Point Vista, which is not possible. Therefore, there must be an error in the elevation gain listed for one of the points of interest. It's possible that the elevation gain for Ruby Falls is incorrect, as it seems unlikely that the hiker would gain more than 8000 ft in elevation between Old Cabin and Ruby Falls. Without more information, it's difficult to say for sure where the error lies.

Statements B, C, and D are not true. Diego would travel a greater distance from D to B than from C to D. He would also create different angles at ΔBDA and ΔBDC, and the distance traveled from A to B would not be the same as from B to C.
According to the given figure, Diego attempts to walk in a sequence of lines to create ΔABD and ΔCDB. He can traverse each side only once and cannot jump from point to point. We need to determine which of the following statements are not true:
A) The distance Diego travels from A to B is the same as the distance traveled from C to D. This statement is not true because the distance from A to B is the sum of the lengths of AB and BD, whereas the distance from C to D is the sum of the lengths of CD and BD, and BD is being counted twice.
B) The distance Diego travels from D to B is the same as the distance traveled from C to D. We cannot determine the truth of this statement without more information about the lengths of the sides.
C) The distance Diego travels from A to B is the same as the distance traveled from B to C. This statement is not true because the distance from A to B is the sum of the lengths of AB and BD, whereas the distance from B to C is the sum of the lengths of BC and BD, and BD is being counted twice.

Equation #2: 4x + 18y = -27
(Choose all correct answers)
Multiply equation #1 by 2
Multiply either equation by -1
Multiply equation #1 by -2
Multiply equation #1 by -3
Answer:
Step-by-step explanation:
To use elimination method, we need to eliminate one of the variables (x or y) by adding or subtracting the two equations. To do this, the coefficients of one of the variables in the two equations should be the same or opposite.
Looking at the two equations:
Equation #1: 2x + 18y = -9
Equation #2: 4x + 18y = -27
We can see that the coefficients of y are already the same in both equations. So, we can eliminate y by subtracting Equation #1 from Equation #2.
However, to do this we need to make sure that the coefficients of x in the two equations are opposites, i.e., one is positive and one is negative.
Therefore, the first step we could take to solve this system using elimination is to multiply Equation #1 by -2 to get:
-4x - 36y = 18
Now the coefficients of x in the two equations are opposites, so we can subtract Equation #1 from Equation #2 to eliminate y and solve for x.
So, the correct answer is:
Multiply equation #1 by -2.

What are algebraic expressions?
A mathematical expression made up of variables, constant algebraic numbers, and algebraic operations are known as an algebraic expression. Everything with a variable value is anything whose value changes over time. Variables in expressions are often represented by letters of the alphabet. Finding the simplified term of the given expression is the goal of simplifying the algebraic expression. We must first understand how to join like terms, factor a number, and the order of operations before we can factorise or simplify the expression. When like terms are combined, the constant terms are divided for the purpose of simplicity and the variables with the same degree are grouped together.

Step-by-step explanation:
Ray is purchasing a laptop that is on sale for 25% off. He knows the function that represents the sale price of his laptop is c(p) = 0. 75p, where p is the original price of the laptop. He also knows he has to pay 8% sales tax on the laptop. The price of the laptop with tax is f(c) = 1. 08c, where c is the sale price of the laptop. Determine the composite function that can be used to calculate the final price of ray's laptop.
Answer:
the final price of Ray's laptop is 89.1% of the original price.
Step-by-step explanation:
To find the composite function that can be used to calculate the final price of Ray's laptop, we need to find the composition of the two functions given:
f(c) = 1.08c (function for calculating the price of the laptop with tax)
c(p) = 0.75p (function for calculating the sale price of the laptop)
We can find the composite function f(c(p)) by substituting c(p) into the formula for f(c):
f(c(p)) = 1.08c(p)
Substituting c(p) with 0.75p, we get:
f(c(p)) = 1.08(0.75p)
Simplifying, we get:
f(c(p)) = 0.81p
Therefore, the composite function that can be used to calculate the final price of Ray's laptop is f(c(p)) = 0.81p.
This means that to find the final price of the laptop, we need to take the original price, multiply it by 0.75 to get the sale price, and then multiply the sale price by 1.08 to add the sales tax. In other words, the final price is:
final price = f(c(p)) = 0.81p = 1.08(0.75p)
final price = 0.81p + 0.081p
final price = 0.891p
Therefore, the final price of Ray's laptop is 89.1% of the original price.

On the first day of school, Ms. Dubacek gave her third-grade students
6 new spelling words to learn. On each day of school after that, she gave the students 3 new spelling words. How many new spelling words had she given the students by the end of the 21st day of school?
Answer: 126 Spelling Words
Step-by-step explanation: I got that because you had to multiply 6 by 21 and you get 126.Answer:
Step-by-step explanation:
On the first day, Ms. Dubacek gave 6 new spelling words.
On each subsequent day, she gave an additional 3 new spelling words.
Therefore, on the second day of school, she gave a total of 6 + 3 = 9 new spelling words.
On the third day of school, she gave a total of 6 + 3 + 3 = 12 new spelling words.
We can see a pattern emerging here: on each day, she gives 6 more words than the previous day.
So on the 21st day of school, she will have given a total of:
6 + (9 + 12 + 15 + ... + 60)
To find the sum of this arithmetic series, we can use the formula:
S = n/2 * (a + l)
where:
S = the sum of the series
n = the number of terms in the series
a = the first term in the series
l = the last term in the series
In this case, we have:
n = 19 (since we're counting from the second day of school to the 21st day)
a = 9 (since that was the total number of spelling words given on the second day)
l = 60 (since that will be the total number of spelling words given on the 21st day)
So, plugging in these values, we get:
S = 19/2 * (9 + 60) = 19/2 * 69 = 655.5
Therefore, by the end of the 21st day of school, Ms. Dubacek will have given her students a total of 6 + 655.5 = 661.5 new spelling words (rounded to the nearest whole number, this is 662).
Find the area of ΔLKJ.
The area of the triangle LKJ is 150 square meters
How to determine the area of the triangleFrom the question, we have the following parameters that can be used in our computation:
The figure
The area of a shape is the measurement of the size of the region enclosed by the shape in a two-dimensional plane.
It is the amount of space inside the shape, usually measured in square units, such as square meters or square feet.
From the figurr, we have
KM^2 = LM * MJ
Substitute the known values in the above equation, so, we have the following representation
12^2 = LM * 16
So, we have
LM = 9
Next, we have
Area = 1/2 * LM * KM
So, we have
Area = 1/2 * 12 * (9 + 16)
Evaluate
Area = 150
Hence, the value of the area is 150

If 10% of a number is 12 and 35%% of the same number is 42, find 25%% of that number.
42 is not the answer
Answer:25% of the number is 30
Step-by-step explanation:
Let's call the number we're looking for "x". We can use the information given in the problem to set up two equations:
10% of x is 12:
0.1x = 12
35% of x is 42:
0.35x = 42
Now we can solve for x:
0.1x = 12
x = 120
0.35x = 42
x = 120
We get the same value for x from both equations, which confirms that our solution is correct. Now that we know x = 120, we can find 25% of that number:
25% of 120 = 0.25 x 120 = 30
Therefore, 25% of the number is 30.

Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options.
18 x minus 15 = 72
50 x minus 25 = 72
18 x minus 9 = 72
3 (6 x minus 3) = 72
x = 4.5
The equations that have the same value of x as the given equation are:
18x - 9 = 72
3(6x - 3) = 72
x = 4.5
The correct options are the third, fourth, and fifth options
Determining the equations that have the same value of xFrom the question, we are to determine the equations that have the same value of x as the given equation
To solve the given equation, we can begin by simplifying it:
3/5 (30 x - 15) = 72
Multiplying both sides by 5/3, we get:
30 x - 15 = 120
Adding 15 to both sides, we get:
30 x = 135
Dividing both sides by 30, we get:
x = 4.5
Now, to check which equations have the same value of x as the above result, we can substitute x = 4.5 in each option and see which ones result in a true statement.
18 x - 15 = 72Substituting x = 4.5, we get:
18(4.5) - 15 = 72
81 - 15 = 72
This is not a true statement, so this option is not correct.
50 x - 25 = 72Substituting x = 4.5, we get:
50(4.5) - 25 = 72
225 - 25 = 72
This is not a true statement, so this option is not correct.
18x - 9 = 72Substituting x = 4.5, we get:
18(4.5) - 9 = 72
81 - 9 = 72
This is a true statement, so this option is correct.
3(6x - 3) = 72Substituting x = 4.5, we get:
3(6(4.5) - 3) = 72
3(24) = 72
This is a true statement, so this option is correct.
x = 4.54.5 = 4.5
This is a true statement, so this option is correct.
Hence, the equations are:
18x - 9 = 72
3(6x - 3) = 72
x = 4.5
