stich3 [128]

Answer:

a: 0.1%

b. No it does not

c. Probably for safety reasons

Step-by-step explanation:

for women: z = (55.9 - 63.9)/3.6 = -2.22

The p-value for z = -2.22 is 0.0132, so only 1.32% of women could walk through without bending

for men: z = (55.9 - 69.7)/3.6 = -3.83

The p-value for z = -3.83 is 0.001, so only 0.1% of men could walk through without bending

Jackie is making flower arrangements. She has 2 roses and 4 daisies. If Jackie wants to make all the arrangements identical and

Alenkasestr [34]

Let's explore possible case scenarios.

---------------------

Case A) Each person gets a rose and a daisy (2 flowers per person)

In this case, Jackie can make 2 such arrangements because she has 2 roses. We have 2 left over daisies.

---------------------

Case B) Each person gets a rose only (1 flower per person)

Only two arrangements are possible for the same reason as case A. In this situation, we have 4 left over daisies.

----------------------

Case C) Each person gets a daisy only (1 flower per person)

We have 4 arrangements possible because we have 4 daisies. The left over flowers are the 2 roses.

-----------------------

Case D) Each person gets 2 roses

Only one such arrangement is possible, so this only applies to one person really. You can say that 2/2 = 1. We have 4 left over daisies in this case.

-----------------------

Case E) Each person gets 2 daisies

Since 4/2 = 2, this means we can make 2 arrangements. There are 2 left over roses.

------------------------

Case F) Each person gets 2 daisies and 1 rose

We can see that 4/2 = 2 and 2/2 = 1, meaning that we can make at most 2 arrangements here. There are no leftovers. In contrast, the other cases do have leftovers of some kind.

------------------------

In short, you can do trial and error to see which case works to fit the conditions your teacher set. Case F is what we go for to have each flower bouquet consist of 2 daisies and 1 rose. We'll get 2 bouquets possible. Notice how cases A through E have at least one left over flower (either of one kind or both types), while case F has no leftovers.

Paul is going to have the exterior of his home painted. Painting USA charges $75.00 to come out and evaluate the house plus $25.

VashaNatasha [74]

Answer:

The most cost-effective company is Painting USA .

Step-by-step explanation:

Given as :

The charges applied by the Painting USA = $ 75 + $ 25 per hour labor charge

The charges applied by the Upscale Home Painting = $ 40 per hour

The total time required to paint the Paul's house = 25 hours

Now, Let the charges applied by the Painting USA = $ x

And charges applied by the Upscale Home Painting = $ y

So, x = $ 75 + $ 25 × 25 hour

Or, x = $ 75 + $ 625

∴ x = $ 700

So, The charges applied by the Painting USA = x = $ 700

And y = $ 40 × 25 hour

∴ y = $ 1,000

So , The charges applied by the Upscale Home Painting = y = $ 1,000

As $ 700 $ 1000

So, x y

Hence The most cost-effective company is Painting USA . Answer
