Two points on a line are (3,8) and (-3,2). What is the slope of the line
The slope of the line passing through the points (3,8) and (-3,2) is 1
The slope of the line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
where m represents the slope
For the line passing through the points (3,8) and (-3,2).
x₁ = 3, y₁ = 8, x₂ = -3, y₂ = 2
Substitute x₁ = 3, y₁ = 8, x₂ = -3, y₂ = 2 into the slope formula above
[tex]m = \frac{2-8}{-3-3}\\\\m = \frac{-6}{-6} \\\\m = 1[/tex]
Therefore, the slope of the line passing through the points (3,8) and (-3,2) is 1

A fruit basket is filled with 8 bananas, 3 oranges, 5 apples, and 6 kiwis. For every 3 kiwis, there are 4... A) Bananas B) Oranges C) Apples
Based on the information given, for every 3 kiwis, there'll be 4 bananas.
Number of bananas = 8
Number of oranges = 3
Number of apples = 5
Number of kiwis = 6
Since the question was that there are 3 kiwis, therefore we have to divide the other fruits by 2 as well. In this case, the number of bananas will be:
= 8/2 = 4
Therefore, from the information depicted above, for every 3 kiwis, there'll be 4 bananas.
In conclusion, the correct option is A.

a minor league baseball team plays 114 games in a season. if the team won 14 more than three times as many games as they lost, how many wins and losses did the team have?
To solve this problem, we can set up an equation. Let L be the number of games lost by the team. We are told that the team won 14 more than three times the number of games they lost, so the number of games won is 3L + 14. The team lost 25 games and won 89 games.
Explanation:To solve this problem, we can set up an equation. Let L be the number of games lost by the team. We are told that the team won 14 more than three times the number of games they lost, so the number of games won is 3L + 14.
The total number of games played is the sum of the games won and the games lost, which is 114. So we have the equation:
(3L + 14) + L = 114
Simplifying the equation, we get:
4L + 14 = 114
Subtracting 14 from both sides, we have:
4L = 100
Dividing both sides by 4, we find that L = 25.
Therefore, the team lost 25 games. To find the number of wins, we can substitute the value of L into the equation we set up earlier:
3L + 14 = 3(25) + 14 = 75 + 14 = 89.
So the team had 89 wins and 25 losses.

In a study of government financial aid for college students, it becomes necessary to estimate the percentage of full-time college students who earn a bachelor's degree in four years or less. Find the sample size needed to estimate that percentage. Use a 0.03 margin of error and use a confidence level of 95%. Complete parts (a) through (c) below.
A.) Assume that nothing is known about the percentage to be estimated.
n=
B.)Assume prior studies have shown that about 55%
of full-time students earn bachelor's degrees in four years or less.
n=
c. Does the added knowledge in part (b) have much of an effect on the sample size?
The required sample size is [tex]1,068[/tex]
A) Significance Level, [tex]\alpha = 0.05[/tex], Margin of Error,[tex]E=0.03[/tex]
The provided estimate of proportion p is, [tex]p=0.5[/tex]
The critical value for significance level, [tex]\alpha = 0.05[/tex] is [tex]1.96[/tex].
The following formula is used to compute the minimum sample size required to estimate the population proportion p within the required margin of error:
[tex]n>=p(1-p)\dfrac{Z_c}{E^2}^{2}[/tex]
Put Values , we get
[tex]n=0.5(1-0.5)\dfrac{1.96}{0.03^2}^{2}\\\\n=0.5(0.5)(65.33)^2\\\\n=0.25(4,268)[/tex]
[tex]n=1067.11[/tex]
Therefore, the sample size needed to satisfy the condition [tex]n>=1067.11[/tex] and it must be an integer number, we conclude that the minimum required sample size is [tex]n=1068[/tex]
Sample size, [tex]1068[/tex]
B) Significance Level, [tex]\alpha = 0.05[/tex], Margin of Error,[tex]E=0.03[/tex]
The provided estimate of proportion p is, [tex]p=0.55[/tex]
The critical value for significance level, [tex]\alpha = 0.05[/tex] is [tex]1.96[/tex].
The following formula is used to compute the minimum sample size required to estimate the population proportion p within the required margin of error:
[tex]n>=p(1-p)\dfrac{Z_c}{E^2}^{2}[/tex]
Put Values , we get
[tex]n=0.55(1-0.55)\dfrac{1.96}{0.03^2}^{2}\\\\n=0.55(0.45)(65.33)^2\\\\n=0.2475(4,268)[/tex]
[tex]n=1056.44[/tex]
Therefore, the sample size needed to satisfy the condition [tex]n>=1056.44[/tex] and it must be an integer number, we conclude that the minimum required sample size is [tex]n=1057[/tex]
Sample size, [tex]1057[/tex]

A flower bed has the shape of a rectangle 21 feet long and 9 feet wide. What is its area in square yards?
Answer:
21 square yards
Step-by-step explanation:
Let's remember that the formula of the area of a rectangle is A = L*W, where L is the length and W the width.
In this case, L = 21 feet and W = 9 feet.
Therefore, A = 21 feet * 9 feet = 189 square feet
We need the answer in square yards. We know that 1 feet equals 1/3 yard (1 feet = 1/3 yard)
As we need square yards, we just square the equation above.
1^2 square feet = (1/3) ^2 square yards
1 square feet = 1/9 square yards
The area is 189 square feet, so we just multiply by 189 on both sides to do the conversion to square yards.
189 square feet = 189*1/9 square yards
189 square feet = 21 square yards
The area of the flower bed is 21 square yards
