Answer to B) is 7 months. Don’t quite understand A) though. More information about how many months you have to show for, would be quite helpful:)

When does ticketmaster charge your credit card?

notsponge [240]

Ticketmaster is one of the better places to buy tickets for many venues such as concerts, plays, and sporting events. When you purchase the tickets for your venue of choice, the credit card will automatically be charged. The money is taken off instantly as soon they confirm the funds are on the card. Generally, you can get a refund within so many days after purchasing the ticket. However, it can take up to 30 days for the funds to be put back onto your credit card. <span />

gladu [14]

Answer: If X = 5, z=<u>-3</u>

If X = 37, z= <u>3.4</u>

Step-by-step explanation:

We know that the formula to find the z-score for any random variable x is given by :-

$z=\dfrac{x-\mu}{\sigma}$

, where $\mu$ = Population mean

$\sigma$ = Population standard deviation.

As per given , we have

$\mu=20\\\\\sigma=5$

Then , the z-score for x =5

$z=\dfrac{5-20}{5}=\dfrac{-15}{5}=-3$

i.e. If X = 5, z=<u>-3</u>

When x =37,then $z=\dfrac{37-20}{5}=\dfrac{17}{5}=3.4$

i.e. If X = 37, z= <u>3.4</u>

Answer:

all in all it's y=x

Step-by-step explanation:

A (4,1); B (0,-2)

G=delta y

--------

delta x

1-(-2)

-------

4-0

3/4=G

3/4=y-1/x-4

4 (y-1)=3 (x-4)

4y-4=3x-12

4y=3x+4-12

y=3/4x-3
