The manager of a cultured pearl farm has received a special order for five pearls between 7 millimeters and 9 millimeters in dia

steposvetlana [31]

Answer:

Probability is 0.3506

Step-by-step explanation:

We are given

mean is 8mm

so, $\mu=8$

standard deviation is 2.2 mm

so, $\sigma=2.2$

x-varies from 7mm to 9mm

At x=7:

we can use formula

$z=\frac{x-\mu}{\sigma}$

we can plug values

$z=\frac{7-8}{2.2}$

$z=-0.45455$

At x=9:

we can use formula

$z=\frac{x-\mu}{\sigma}$

we can plug values

$z=\frac{9-8}{2.2}$

$z=0.45455$

So, z is between -0.45455 and 0.45455

$-0.45455\leq z \leq 0.45455$

now, we can use normal distribution table

and we get

Probability is 0.3506

How do you write 0.045 as a reduced fraction

Anvisha [2.4K]

0.045 = 45/1000

Divide top and bottom by their greatest common factor.
It looks to me as though the greatest common factor of 45 and 1,000 is 5 .
Divide top and bottom by 5 and we have <u>9/200</u> . That's the simplest form.
