Vesna [10]
The sample std. dev. will be (14 inches) / sqrt(49), or (14 inches) / 7, or 2 inches.

Find the z score for 93.8 inches:
       93.8 inches - 91.0 inches          2.8 inches
z = ------------------------------------- = ----------------- = 1.4
                    2 inches                         2 inches

Now find the area under the standard normal curve to the left of z = +1.4.

My calculator returns the following:

normalcdf(-100,1.4) = 0.919.  This is the probability that the mean annual precipitation during those 49 years will be less than 93.8 inches.

Alika [10]

Options:

A.) square root

B.) exponential

C.) absolute value

D.) cube root

Answer : A) square root

We know area of square having side 's' = s* s = s^2

For example

Area of square =  16 cm^2

To find side we take square root

Area = (side)^2

16 = (side)^2

Take square root on both sides

\sqrt{16}= \sqrt{side^2}

4= side

Betsy knows that the area of the rug is A square feet.

Area A = (side)^2

\sqrt{A} = side

So answer is square root.
