When -3 is squared it becomes 9 then -3x5 is -15 so put that back into the equation 9-15+9= 4

√2 times √800 anyone know?

jeka94

$\sqrt{2} \times \sqrt{800}$

$\sqrt{2} \times 20 \sqrt{2}$

$\sqrt{2} \times \sqrt{2} = \sqrt{4} \: = 2$

$20 \times 2 = 40$

$therefore \: \: \: \sqrt{2} \times \sqrt{800} = 40$

The amount of time it takes Renee to go grocery shopping is continuous and uniformly distributed between 18.5 minutes and 40.5 m

balandron [24]

Answer:

47.73% probability that it takes Renee at most 29 minutes 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.

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

Uniformly distributed between 18.5 minutes and 40.5 minutes.

This means that $a = 18.5, b = 40.5$

What is the probability that it takes Renee at most 29 minutes to go grocery shopping

$P(X \leq 29) = \frac{29 - 18.5}{40.5 - 18.5} = 0.4773$

47.73% probability that it takes Renee at most 29 minutes to go grocery shopping
