A normal distribution has a mean of 10 and a standard deviation of 1. What is the probability of selecting a number that is at m

Len [333]

Answer: 0.500

Step-by-step explanation:

Given : A normal distribution has a mean $(\mu)$ of 10 and a standard deviation $(\sigma)$ of 1.

Let x be a random variable that represents numbers .

The probability of selecting a number that is at most 10 will be

$P(x\leq10)=P(\dfrac{x-\mu}{\sigma}\leq\dfrac{10-10}{1})\\\\=P(z\leq0)=0.500$

As the area occupied by standard normal curve less than equal to 0 = 0.500

So, required probability = 0.500

Dina and Masha started out on a 12 mi bike path at the same time. When Dina reached the end of the 12 mi, Masha still had 3 mi l

Anna35 [415]

Answer:

6 mph

Step-by-step explanation:

Use formula

$D=r\cdot t,$

where

D = distance

r = rate

t = time

In your case,

D = 12 mi

D = 12 mi

r = 8 mph

t = ?

So,

$12=8t\\ \\t=\dfrac{12}{8}=\dfrac{3}{2}=1.5\ hours$

<u>Masha:</u>

D = 12 - 3 = 8 mi

r = ?

t = 1.5 hours

Then

$9=1.5r\\ \\r=\dfrac{9}{1.5}=\dfrac{90}{15}=6\ mph$
