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

-2x-3y=-7<br> y+1=x<br> solve for y and x
sertanlavr [38]

Answer:

x = 2 and y = 1

Step-by-step explanation:

First, solve for y by substituting the second equation as x into the first equation

-2x - 3y = -7

-2(y + 1) - 3y = -7

Simplify and solve for y

-2y - 2 - 3y = -7

-5y - 2 = -7

-5y = -5

y = 1

Solve for x by plugging in 1 into the second equation

y + 1 = x

1 + 1 = x

2 = x

So, the answer is x = 2 and y = 1
