Answer:  The customer will pay $17.35 for the shirt.

Step-by-step explanation:  Given that a shirt costs $19.85 and a customer has a coupon that will save her $2.50 on the price of the shirt.

We are to find the amount that the customer will pay for the shirt.

Given that

the original cost of the shirt = $19.85

and

the price that the customer save by using coupon = $2.50.

Therefore, the total cost that the customer will pay for the shirt is given by

\$19.85-\$2.50=\$17.35.

Thus, the customer will pay $17.35 for the shirt.

solong [7]

Answer:

The Correct Statement is

• Use the distance formula to prove the lengths of the opposite sides are the same.

Step-by-step explanation:

The statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent is,

• Use the distance formula to prove the lengths of the opposite sides are the same.

Distance Formula is given by

l(AB) = \sqrt{((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} )}

For Parallel Lines:

Use the slope formula to prove the slopes of the opposite sides are the same.

For Perpendicular Lines:

Use the slope formula to prove the slopes of the opposite sides are opposite reciprocals.

As a company manager for claimstat corporation there is a 0.40 probability that you will be promoted this year. there is a 0.72
Charra [1.4K]
Suppose P denotes the event of getting promoted and R the event of getting a raise. Then

\mathbb P(P\cup R)=\mathbb P(P)+\mathbb P(R)-\mathbb P(P\cap R)
\implies0.72=0.40+\mathbb P(R)-0.25
\implies\mathbb P(R)=0.57

Now it sounds like you're asked to find \mathbb P(R\mid P), which the definition of conditional probability says is equivalent to

\mathbb P(R\mid P)=\dfrac{\mathbb P(R\cap P)}{\mathbb P(P)}=\dfrac{0.25}{0.40}=0.625

Claire is a manager at a toy packaging company. The company packs 80 boxes of toys every hour for the first 3 hours of the day.
Stells [14]

Answer:

See the attached figure.

Step-by-step explanation:

Modeling each part as a function.

Let x is hours of the working day

The company packs 80 boxes of toys every hour for the first 3 hours of the day. ⇒ y₁ = 80 x , x ∈ [0,3]

At the end of the 3 hours The company packs = 80 * 3 = 240

They stop packaging for the next 2 hours in order to carry out a training session. ⇒ y₂ = 240 , x ∈ [3,5]

Then, for the next 4 hours, they pack 20 boxes of toys every hour

y₃ = 20x + c , x ∈ [5,9]

To find c, y₂ = y₃ at x =5

∴ 240 = 20 * 5 + c

∴ c = 240 - 20 * 5 =240 - 100 = 140

∴ y₃ = 20x + 140 , x ∈ [5,9]

So,

y₁ = 80 x , x ∈ [0,3]

y₂ = 240 , x ∈ [3,5]

y₃ = 20x + 140 , x ∈ [5,9]

The graph models the piecewise function for the given situation is as shown in the attached figure.
