210

since when you multiply two negative numbers for example -15 times a negative 14 your answer will be positive then you do 15 times 14 which gives you positive 210.

Feliz [49]

So what you do is see all the denomenators and factor them (denomenaotrs are the bottom numbres)

10,4,10,25
10=2 times 5
4=2 times 2
10=2 times 5
25=5 times 5
we need to include all of them so we need at leas two 2's, and two 5's
2 times 2 times 5 times 5=100
leact common denomator is 100

Answer:

16 2/3 %

Step-by-step explanation:

Since the price went down, we are find the percent decrease.

Percent decrease = (original price - new price)/ original price

= (90 - 75)/90

=15/90

.1666666666666

Changing to percent form

16.6666666666666666666666%

The amount of time it takes Evelyn to go grocery shopping is continuous and uniformly distributed between 20 minutes and 44 minu

vivado [14]

Answer:

85.71% probability that it takes Evelyn less than 38 minutes given that it takes less than 41 minutes for her to go grocery shopping

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

$P(X < x) = \frac{x - a}{b-a}$

Uniformly distributed between 20 minutes and 44 minutes.

This means that $a = 20, b = 44$ .

What is the probability that it takes Evelyn less than 38 minutes given that it takes less than 41 minutes for her to go grocery shopping

We know that it takes less than 41 minutes, so we can update b to 41.

$P(X < 38) = \frac{38 - 20}{41 - 20} = 0.8571$

85.71% probability that it takes Evelyn less than 38 minutes given that it takes less than 41 minutes for her to go grocery shopping
