Answer:

z=-5

Step-by-step explanation:

You have the equation 3z-1-2z=-76-14z

Step 1- Add 76 to both sides

3z+75-2z=-14z

Step 2- Subtract 2z from 3z to get z

z+75=-14z

Step 3- Subtract z from both sides

75= -15z

Step 4- Divide -15 from both sides

-5=z

Answer:

Hello! :) I hope I’m correct!!

Step-by-step explanation:

I think the answer should be: z = -5

Okay so the steps for this problem is;

1. First, simplify both sides of the equation.

2. Next, add 14z to both sides

3. Now, add 1 to both sides.

4. Finally, you have to divide both sides by 15

This will give you the answer.

<h3 /><h3>Therefore, the answer to your question is z = -5</h3><h3 />

Your answer will be -5.

Hope this helps!! Have a great day! If you have any questions about these steps, feel free to ask! (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧

A coffee shop collected the following information regarding purchases from 110 of its customers 59 purchased coffee 39 purchased

Andrej [43]

Answer:

Let X be the number of customer purchased coffee

Let Y be the number of customer purchased donuts

Then $X\cap Y$ is the number of customer purchased both coffee and donuts

$X\cup Y$ is the number of customer purchased both coffee or donuts

The Number of customers purchased only Coffee:

Number of customers purchased only donuts =n(X -Y)

$n( X -Y) = n(X) - n(X \cap Y)$

n(X-Y) = 59 -16

n(Y - X) = 43

The Number of customers purchased only donuts:

Number of customers purchased only donuts =n(Y -X)

$n(Y - X) = n(Y) - n(X \cap Y)$

n(Y - X) = 39 -16

n(Y - X) = 23

The Number of customers did not purchase either of these items:

Number of customers did not purchase either of these items = $n(X\cup Y)^{\prime}$

First lets find $n(X\cup Y)$

$n(X\cup Y) = n(X) + n(Y) - n( X \cap Y)$

$n(X\cup Y) = 59 + 39 - 16$

$n(X\cup Y) = 82$

$n(X\cup Y)^{\prime}$ = $110 - n(X\cup Y)$ = 28

Generally PV of annuity with growth is mathematically represented as

where PV is present value

PV of annuity with growth X= $(P/ (r-g)) * (1- ((1+g)/(1+r))^n)$

$\frac{P}{\frac{8\%}{y12-0.2\%} } *(1-((1+0.2\%)/(1+8.5\%/12))^(^8^*^1^2^)^)=65000$

$196.7213115P* 0.384791918=65000$

$196.7213115P=65000/0.384791918$

$196.7213115P=168922.4668$

$P= 168922.4668/196.7213115$

$P= 858.6892063$

$First\ monthly\ payment= $858.69$
