Answer:

$36\text{ inch}^2$

Step-by-step explanation:

We have been given an image of outdoor carpet needed for a hole. We are asked to find the area of outdoor carpet needed for this hole.

We can see that there are two pieces needed to cover the given hole.

One pieces equal 24 square inches and another pieces equal 12 square inches.

$\text{Area of carpet needed to cover the hole}=24\text{ inch}^2+12\text{ inch}^2$

$\text{Area of carpet needed to cover the hole}=36\text{ inch}^2$

Therefore, $36\text{ inch}^2$ of carpet is needed to cover the given hole.

Nitella [24]

The size of the sample should be obtained at 2401 in order to be 95% confident

Given that:

Margi of error, $ME=0.02$

Population proportion, $p=0.50$

To Find: The size of the sample that should be obtained in order to be 95% confident

Let the size of the sample be n

Using formula,

$n=(p*(1-p))*(z(0.05/2)/ME)^{2} \\n=(0.5*(1-0.5))*(1.96/0.02)^{2} \\n=0.25*9604\\n=2401$

Therefore, the size of the sample should be obtained at 2401 in order to be 95% confident

(01.02 HC) Marla has $95.50 in her savings account. She deposits $5 every week. Her mother also deposits $20 into the account ev

stepan [7]

Part A:

Variable is a symbol for a number we don't know yet. It is usually a letter like x or y but can be any letter.
Example: 6z means 6 times z, and "z" is the variable.

Hence, the variables are c and w. [ Choose any one for your answer ]

Coefficient is any number used to multiply a variable.
Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.

Hence, the coefficients are 20 and 5. [Choose any one for your answer]

A constant is a fixed value which does not change regardless of the variables entered.

Hence, the constant is 95.50

Part B:

Weeks saved (w) = 20

Cars washed (c) = 5

20c + 5w + 95.50 = (20 * 5) + (5 * 20) + 95.50 = 100 + 100 + 95.50 = 295.50

Hence, Marla will have $ 295.50 in her account.

Part C:

In 20c + 5w + 95.50, Marla's mom deposits $ 20 after every car wash.

If Marla's mom deposits only $ 10 after every car wash, then, the new equation would be : 10c + 5w + 95.50

Hence, the coefficient will change from 20 to 10.
