Answer:

$\frac{3}{5}$

Step-by-step explanation:

Given:

$\frac{4}{5} \div \frac{4}{3}$

Required:

Simplify

$\frac{4}{5} \div \frac{4}{3}$

Turn the division operation to multiplication, and flip the fraction by your right upside down

$\frac{4}{5} \times \frac{3}{4}$

4 cancels out 4

$\frac{1}{5} \times \frac{3}{1}$

$\frac{1 \times 3}{5 \times 1}$

$\frac{3}{5}$

Therefore, $\frac{4}{5} \div \frac{4}{3} = \frac{3}{5}$

The average speed of a car driving down freeway is 70mph with a standard deviation of 5mph. Thid speed is normally distributed.

ikadub [295]

Answer:

0.081,0.2621,0.645,0.919

Step-by-step explanation:

Let X be the average speed of a car driving down freeway

Given that X is normal with mean as 70mph with a standard deviation of 5mph.

To convert to Z score we do

$Z =\frac{x-70}{5}$

a) the probability that a randomly selected car is driving more than 77mph

$=P(X>77)\\=P(Z>1.4)\\=0.081$

b) probability that a randomly selected car is driving between 65 and 69 mph

= $P(-1$

c) the probability that a randonly selected car is driving between 67 and 77mph

= $P(-0.6$

d) the probability that a randomly selected car is driving less than 77mph

$=P(Z$
