Answer:

The answer to your question is 236 ft²

Step-by-step explanation:

Data

height = 5 ft

width = 6 ft

length = 8 ft

Area = ?

Process

I will consider that the crate is a rectangular prism which has 6 sides

1.- Find the area of the sides that measure 8 x 6

Area = 2 (8 x 6)

        = 2(48)

        = 96 ft²

2.- Find the area of the sides that measure 8 x 5

Area = 2(8 x 5)

Area = 2(40)

Area = 80 ft²

3.- Find the area of the sides that measure 6 x 5

Area = 2( 6 x 5)

Area = 2(30)

Area = 60

4.- Find the total area

Area = 96 + 80 + 60

Area = 236 ft²

5.- Conclusion

She needs 236 ft² of paint

A market research analyst claims that 32% of the people who visit the mall actually make a purchase. You think that less than 32
denis23 [38]

Answer:

The null hypothesis is H_0: p \geq 0.32

The alternative hypothesis is H_1: p < 0.32

Step-by-step explanation:

State the null and alternative hypotheses to test that less than 32% of mall visitors make a purchase

At the null hypothesis, we test if the proportion is of at least 32%, that is:

H_0: p \geq 0.32

We are testing if less than 32% of visitors make a purchase, so, at the alternative hypothesis, we test if the proportion is less than 32%, that is:

H_1: p < 0.32

Four polynomials are shown below:
max2010maxim [7]
The degree of a polynomial is the value of the highest exponent a variable is raised to (i.e., the degree of the equation y=x^{2} is 2, since the highest exponent of a variable is 2. 

If we apply this concept to your list of polynomials, we see that polynomial A and polynomial D both have x^{5} terms, so they are both fifth-degree polynomials. However, your answer must also be a trinomial (a polynomial with three terms.) If we look at polynomials A and D, we see that only polynomial A has three terms, so that must be the answer!

Let me know if you have any questions :)

What is the first term for an arithmetic sequence with a12 = 56 and a21=101?
Alenkinab [10]
The first term is -43.

Explanation:

an = a + (n - 1)d

a12 = a + 11d = 56, first equation
a21 = a + 20d = 101, second equation

Subtract the second equation from the first equation, cancelling +a and -a
11d - 20d = 56 - 101
-9d = -45
d = 5

Subtitute d into the first equation
a + 99 = 56
a = -43

a refers to the first term, hence the first term is -43.
