Ghella [55]

Answer:

The equations which describe this situation are:

C. f + (2f) + (2f + 2.50) = 11.25

E. 5 f = 8.75

Step-by-step explanation:

Here, the number of loaves of bread purchased = 3

The price of a loaf of French bread = f

The price of whole grain bread = 2 x ( Price of the french bread)

= 2 x (f) = 2 f

The price of cinnamon raisin bread

= ( Price of the whole grain bread) + $2.50

= 2 f + $2.50

Also, the total price paid for the 3 loaves of bread = $11.25

⇒ The cost of ( French + whole grain + Cinnamon raisin) bread = $11.25

or, f + (2f) + (2f + 2.50) = 11.25

or, 5 f = 11. 25 - 2.50 = 8.75

or, 5 f = 8 . 75

Hence the equations which describe this situation are:

C. f + (2f) + (2f + 2.50) = 11.25

E. 5 f = 8.75

Answer:

Option A) 0.0074

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 110

Sample mean, $\bar{x}$ = 20

Sample size, n = 100

Alpha, α = 0.05

Population standard deviation, σ = 115.35

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 110\\H_A: \mu \neq 110$

We use two-tailed z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{115.35 - 110}{\frac{20}{\sqrt{100}} } = 2.675$

Now, we calculate the p-value from the standard normal table.

P-value = 0.0074

Thus, the correct answer is

Option A) 0.0074
