Answer: 161 m^2
Step-by-step explanation:
The surface area composes of 4 triangles and 1 square.
The side length of the square is 7 m, so the area is 49 m^2 because the area of a square is the side length^2.
Each of the triangles has a base of length 7 m and a height of 8 m, so the area of each triangle is 7m*8m/2 = 28 m^2 because the area of a triangle is the base*height/2.
Since there are 4 triangles, the total surface area of the 4 triangles is 28 m^2 * 4 = 112 m^2.
Adding that to the area of the square, we get 49 m^2 + 112 m^2 = 161 m^2

[tex]\sf y = \dfrac{17}{2}[/tex]
explanation:
[tex]\sf 7y-4=9y+13-4y[/tex]
collect variables in one side
[tex]\sf 7y -9y +4y = 13 +4[/tex]
simplify by addition and subtraction
[tex]\sf 2y = 17[/tex]
divide both sides by 2
Hence, ,final answer:
[tex]\sf y = \dfrac{17}{2}[/tex]
Answer:
A. y = 17/2
Step-by-step explanation:
Given equation:
7y - 4 = 9y + 13 - 4y
Collect like terms:
7y - 4 = 9y - 4y + 13
Combine like terms:
7y - 4 = 5y + 13
Subtract 5y from both sides:
2y - 4 = 13
Add 4 to both sides:
2y = 17
Divide both sides by 2:
y = 17/2

The number of chairs Amal can paint varies directly with the amount of time she spends painting. Amal can paint 7 chairs in 3 hours. How many chairs can Amul paint in 15 hours? Enter your answer in the box.
Answers
Answer:
35
Explaination:
This problem can be represented by the equation: (7/3)=(x/15) Then solve for x, which is 35.
Amul can paint 35 chairs in 15 hours
Let the number of chairs Amal can paint be represented as N
And amount of time she spends painting be represented as t
such that
The number of chairs Amal can paint varies directly with the amount of time she spends painting will be expressed as
N∝t
Introducing the constant of proportionality,K becomes
N=Kt
Amal can paint 7 chairs in 3 hours.K becomes
N=Kt
7=K3
K=7/3
Now if Amul paint in 15 hours, she would paint
N=Kt
N=7/3 X 15
N=35 Chairs

y=252/5=50.4
Step-by-step explanation:
[tex](A)\ 9y-252=4y\\(B)\ 5y=252\\(C)\ y= \frac{252}5 = 50.4[/tex]
In step A we multiplied both sides by the least common multiple of the denominators, in order to deal with only integers for as long as possible.
In step B you subtract 4y and add 252 to both sides ("moving them on the other end of the equal sign").
In step C you finally divide by 5 to isolate y.

The correlation coefficient measures the relationship between the two variables
The correlation coefficient is 0.234
How to determine the correlation coefficientThe formula of correlation coefficient is:
[tex]r = \frac{1}{n - 1} * \sum{(\frac{x - \bar x}{\sigma_x})*(\frac{y - \bar y}{\sigma_y})[/tex]
Using the dataset from the complete question, we have:

How many whale sharks would a researcher need to measure so that 90% confidence level would have a margin of error of 0.25
Answers

What is margin of error?
Margin of error is used to determine by what value there is deviation from the real value. Margin of error (E) is given by:
[tex]E=Z_\frac{\alpha}{2} *\frac{standard\ deviation}{\sqrt{sample\ size} }[/tex]
The 90% confidence level have a z score of 1.645. Hence for E = 0.25, standard deviation = 5.7 feet, hence:

5.16 Identify hypotheses, Part II: Write the null and alternative hypotheses in words and then symbols for each of the following situations. (a) Since 2008, chain restaurants in California have been required to display calorie counts of each menu item. Prior to menus displaying calorie counts, the average calorie intake of diners at a restaurant was 1100 calories. After calorie counts started to be displayed on menus, a nutritionist collected data on the number of calories consumed at this restaurant from a random sample of diners. Do these data provide convincing evidence of a difference in the average calorie intake of a diners at this restaurant?
Answers
Answer:
H₀: µ = 1100 vs. Hₐ: µ ≠ 1100.
Step-by-step explanation:
A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.
It is a hypothesis of no difference.
It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.
For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.
Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.
The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.
It is also known as the research hypothesis and is denoted by Hₐ.
In this case the hypothesis can be defined as follows:
Null hypothesis:
H₀: The average calorie intake of a diner at this restaurant is 1100, i.e. µ = 1100.
Alternate hypothesis:
Hₐ: The average calorie intake of a diner at this restaurant is different from 1100, i.e. µ ≠ 1100.
The same sequence may be defined in three ways: 1) f(x) = 3x + 4 for x = {1, 2, 3, ...}, 2) a1 = 4 and an + 1 = an + 3 for n = {1, 2, 3, ...} and 3) an = 4 + 3(n − 1) for n = {1, 2, 3, ...}.
They are all supposed to generate the same values, but one version may contain an error. If one version contains an error, identify the one with the error and fix it.

I got x+y is (less than or equal to) 55 for the first inequality and 60x+40y>600 for the second one!

Since Blaine can sell a maximum of 55 tickets, the first inequalitly is x+y is less than OR EQUAL TO 55. Since the tickets in the back section cost $40 each, 40y represents the money made from those tickets. Blaine needs to make 600 in sale so the inequality is 60x+40y>600.
