The answer is 25%

Take the result and divide it by the original number to get the increase.

110/88=1.25

Then subtract the 1 and you get .25

.25 = 25%

Use complete sentences to describe the steps involved in solving x2 − 64 = 0 two different ways.

muminat

Answer:

1. First, add 64 to bith sides, cancelling one out and taking it to the other side, then dividing by two, giving you x=32.

2. Subtract 2x and take it to the other sude of the equation. Then divide -2 by -64, giving you x=32, due to the negative cancelling (turning to a positive).

Suppose the time it takes a barber to complete a haircuts is uniformly distributed between 8 and 22 minutes, inclusive. Let X =

salantis [7]

Answer:

$P(X>14)= 1-P(X$

And replacing we got:

$P(X>14)= 1- \frac{14-8}{22-8}= 0.5714$

The probability that a randomly selected barber needs at least 14 minutes to complete the haircut is 0.5714

Step-by-step explanation:

We define the random variable of interest as x " time it takes a barber to complete a haircuts" and we know that the distribution for X is given by:

$X \sim Unif (a= 8, b=22)$

And for this case we want to find the following probability:

$P(X>14)$

We can find this probability using the complement rule and the cumulative distribution function given by:

$P(X$

Using this formula we got:

$P(X>14)= 1-P(X$

And replacing we got:

$P(X>14)= 1- \frac{14-8}{22-8}= 0.5714$

The probability that a randomly selected barber needs at least 14 minutes to complete the haircut is 0.5714

Your paycheck this week is $241. You put the $114 in a savings account that pays an interest

antiseptic1488 [7]

Answer:

$122.9

Step-by-step explanation:

Given data

Principal= $114

Rate= 3.9%

Time= 2 years

The amount in the account is given as

A=P(1+rt)

substitute

A=114(1+0.039*2)

A=114(1+0.078)

A=114(1.078)

A=$122.9
