Can anyone give me the answer to 18.. Part A and B...if u can explain too please
Answers
A cube is a solid with 6 faces. All faces are congruent squares. All edges of the cube are sides of the square faces. Since all faces are congruent squares, all edges of the cube are congruent segments. You can find the lengths of all edges of the cube since they are all equal.
18 Part B
The volume of a cube is the cube of the edge.
If you are given the volume of a cube, take the cubic root of the volume to find the edge of the cube.
edge = cubic root of 64 cm^2 = 4 cm
Since we now know the edge, we can find the area of a square face.
A = side^2 = (4 cm)^2 = 16 cm^2
Each face of the cube has an area of 16 cm^2.
The area of the square hole in the toy is 8 cm^2, so the block will not fit in the square hole.

What is the distance between points (5, 5) and (1, 5) on a coordinate plane
Answers
The distance formula can be used to solve this equation.
[tex]d= \sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2[/tex]
After plugging in all the values you get:
[tex]d= \sqrt{(5-1)^2+(5-5)^2} [/tex]
This simplifies to [tex]d= \sqrt{16} [/tex], so the distance between the two points is 4.
Decorations for school dances take 1/5 of the student council's budget. Entertainment takes 3/10 of the budget. What fraction of the budget is left?
PLEASE INCLUDE STEPS!!!!!
Answers
first, we need to find 1/5 + 3/10. in order to add these, we need to find a common denominator. because 5 divides 10 evenly, it would be easiest to use 10 as a denominator.
3/10 already has 10 in the denominator, so we don't have to touch it yet.
to get 1/5 to have a denominator of 10, we need to multiply both the top and bottom of the fraction by 2 (because 2 x 5 is 10). we can do this because we're multiplying by 2/2, which is equal to 1. multiplying by 1 does not change the value of the fraction.
1 x 2 = 2, and 5 x 2 = 10, so our new fraction equivalent to 1/5 is 2/10.
now, we can add 3/10 + 2/10. when you add fractions, you add the numerators and keep the common denominators. so 3/10 + 2/10 = (3+2)/10 = 5/10. so 5/10 of the budget has been used.
to find out what fraction is left, we subtract 1 - 5/10. 1 is equal to any number over itself (as we saw earlier with 2/2) so we're subtracting 10/10 - 5/10. this gets us to 5/10. so 5/10 of the budget is left. 5/10 can be reduced to 1/2 in simplest form, since you can divide both 5 and 10 by their greatest common factor, which is 5. so 1/2 of the budget is left.

The sum of the digits of a two-digit number is 6. If the digits are reversed, the difference between the new number and the original number is 18. Find the original number
Answers
There are only a few two numbers with a sum of 6. They are:
1 and 5
2 and 4
3 and 3
So basically, there are only three sets of possible two digit + reversed two digit numbers.
3 and 3, we can just eliminate that because it's the same thing both ways around.
1 and 5, the difference between 15 and 51 is way too much.
So therefore it would have to be the pairs of 2 and 4.
Since the difference between the new number and the original number is 18, the new number would have to be 42 and the old one 24.
So the original number would be 24.
when the digits are reversed, the new number is 10x+y
x+y=6 =>x=6-y
(10y+x)-(10x+y)=18
9y-9x=18
y-x=2
replace x with 6-y: y-(6-y)=2 =>y=4
x=6-4=2
so the original number is 42, the new number is 24
or the original number is 24, the new number is 42

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?
Answers
[tex]n=p(1-p)\left( \frac{z_{\alpha/2}}{M} \right)^2[/tex]
Part A:
Given a margin of error of 0.03 a confidence level of 95%. Since we have know prior knowledge of the proportion estimate, we make use of the consevartive proportion estimate of 50% or 0.05.
[tex]z_{\alpha/2}[/tex] for 95% confidence is 1.96.
Therefore, the required sample size is given by
[tex]n=0.5(1-0.5)\left( \frac{1.96}{0.03} \right)^2 \\ \\ =0.5(0.5)(65.33)^2=0.25(4,268) \\ \\ =1,067.11[/tex]
Therefore, the required sample size is 1,068.
Part B:
Given that prior studies have shown that about 55% of full-time students earn bachelor's degrees in four years or less.
Thus, p becomes 55% = 0.55 and the required sample size is given by
[tex]n=0.55(1-0.55)\left( \frac{1.96}{0.03} \right)^2 \\ \\ =0.55(0.45)(65.33)^2=0.2475(4,268) \\ \\ =1,056.44[/tex]
Therefore, the required sample size is 1,057.
Part C:
When we dont know the additional infromation (i.e. in part A), we obtained that the required sample size is 1,068 but after we know the information our sample size becomes 1,057.
Though there is a difference between both sample sizes but the difference is not much and hence, the knowledge of the additional information does not 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]
C)The difference between both the part a and b is very less so added knowledge of the extra information does not have much effect on sample size.

A flower bed has the shape of a rectangle 21 feet long and 9 feet wide. What is its area in square yards?
Answers
Brainlist please! :)
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

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?
Answers
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.
From the set {70, 20, 15}, use substitution to determine which value of x makes the equation true.
5x = 75
