So 32 dollars for 8 cookies.

To find the price of one item, you take the amount of items, and divide it by the price:

32 / 8 = 4 dollars for the price of 1 cookie.

Answer:

$4.00

Step-by-step explanation:

If it costs 32 dollars for 8 cookies, it would make sense to divided the total by the part.

Since 32 is the total for 8 cookies, we can mark it as total or whole.

And 8 is part of it.

So it would be reasonable for us to divided 32 by 8

We would get 4

So it costs 4 dollars for one cookie, let's check.

4+4+4+4=16

Another 4+4+4+4=16

16+16=32 dollars.

And we added 8 cookies!

The answer is 4 dollars for 1 cookie.

My name is Ann [436]

Answer:

Yes

Step-by-step explanation:

Given,

Population mean Z = 600

Sample mean, µ = 586.50

Size of the sample, n = 10

Standard deviation, σ = 26.77

The testing hypothesis is,

Null hypothesis = µ<600

Alternative hypothesis = µ≥600

The test statistics is the calculated value of Z,

(Z- µ)/(σ/√n)

= (600-586.50)/(26.77/√10)

= (13.5*3.1623)/26.77

= 42.691/26.77

= 1.5947

And at 5% level of significance, the table value of Z = 1.644

Here, calculated Z<Table value of Z, so we accept the null hypothesis.

So, the null hypothesis is accepted. The mean value of the laptop is less than 600.

Company A manufactures and sells gidgets. The owners have determined that the company has the monthly revenue and cost functions

jasenka [17]

Answer:

Option A. 356 gidgets

Step-by-step explanation:

we have

R(x) ----> the monthly revenue function

C(x) ---> the monthly cost function

x ----> the number of gidgets sold

$R(x)=16x$

$C(x)=12x+1,424$

we know that

Break-even means that the revenue equals cost

$16x=12x+1,424$

solve for x

$16x-12x=1,424$

$4x=1,424$

$x=356\ gidgets$
