A grocery store chain has been tracking data on the number of shoppers that use coupons. The data shows that 71% of all shoppers

mariarad [96]

Answer: (0.685, 0.735)

Explanation:

First, we will compute the confidence level of the given:

$\text{ Confidence Level }=\frac{36}{40}\times100\%=90\%$

They gave us a margin of error of 0.025. From the given, we know that p=71%=0.71.

The confidence interval would then be:

$\begin{gathered} (p-E,p+E) \\ =(0.71-0.025,0.71+0.025) \\ =(0.685,0.735) \end{gathered}$

Therefore, the confidence interval would then be (0.685, 0.735)

What is the surface area of a square pyramid with a slant height of 6cm and the length of one side of the square base is 5cm

erica [24]

Answer:

S = 85cm^2

Step-by-step explanation:

The surface area of a square pyramid is given by the following formula:

$S=2hb+b^2$

where it has taken into account the sum of the area of a square and four triangles:

$4(\frac{hb}{2})+b*b=2bh+b^2$

h: slant height = 6cm

b: base = 5cm

By replacing in the formula you obtain:

$S=2(5cm)(6cm)+(5cm)^2=85cm^2$

hence, the surface area is 85cm^2

{15×115-(-3)}(4-4)÷3{5+(-3)×(-6)} simplify the expressions <br>

Lena [83]

Answer:

Step-by-step explanation:

Alright, so we all know that the order is { [ ( ) ] } right?

1. { }

2. [ ]

3. ( )

Those are the IMPORTANT orders!

So first, 15 x 155 is 2325, and - and - is a +.

The first part is 2328, ( 2325 + 3 ).

The second part is 4-4 ÷ 3, don't forget, PEMDAS!

Prentices

Exponents

Multiplication

Division

Addition

Subtraction

So no, you will not divide 4 and 3 first.

First, do 4 - 4 which is 0.

And then 0 ÷ 3 which is 0.

The third part is 3 { 5 + ( - 3 ) x ( - 6 ) }

The outside 3 means that we will multiply after we get the answers.

But first, -3 x -6 is 18 because - and - is +.

Now, 5 + 18 which is 23.

3 times 23 is 69!

The fourth part is really easy, just add them all up!

2328 x 0 + 69

And lastly, we know that the answer is 0.
