Assume the readings on thermometers are normally distributed with a mean of 0 degrees C and a standard deviation of 1.00 degrees

lozanna [386]

Answer: 0.0035

Step-by-step explanation:

Given : The readings on thermometers are normally distributed with a mean of 0 degrees C and a standard deviation of 1.00 degrees C.

i.e. $\mu=0$ and $\sigma= 1$

Let x denotes the readings on thermometers.

Then, the probability that a randomly selected thermometer reads greater than 2.17 will be :_

$P(X>2.7)=1-P(\xleq2.7)\\\\=1-P(\dfrac{x-\mu}{\sigma}\leq\dfrac{2.7-0}{1})\\\\=1-P(z\leq2.7)\ \ [\because\ z=\dfrac{x-\mu}{\sigma}]\\\\=1-0.9965\ \ [\text{By z-table}]\ \\\\=0.0035$

Hence, the probability that a randomly selected thermometer reads greater than 2.17 = 0.0035

What is the answer to this?

Yanka [14]

DEF= 6 ft^2

A= 1/2*b*h

Plug in what you know.

6= 1/2*4*h

Multiply like terms.

6=2*h

Divide 2 on both sides.

3=h

If the base of ABC= 12

12/4=3

3*3=9

A= 1/2*b*h
A= 1/2*12*9
A= 1/2*84
A= 42

The area of ABC is 42 ft^2

I hope this helps!
