Answer:

Step-by-step explanation:

Today's calculators have statistical functions built in.

A. Here we use:

normalcdf(10,310,205,35), WHICH returns 0.999.

B. normalcdf(135,275, 205,35) = 0.954

C. normalcdf(240, 10000, 205, 35) = 0.159

Answer:

$14 ( 5)^{\frac{1}{4}} p^{\frac{1}{4}} q^{\frac{1}{2}} r^{2}$

Step-by-step explanation:

The expression to simplify in this problem is

$7\sqrt[4]{80pq^2r^8}$

Which can be rewritten as

$7(80pq^2r^8)^{\frac{1}{4}}$

Or also as

$7\cdot 80^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot (q^2)^{\frac{1}{4}} \cdot (r^8)^{\frac{1}{4}}$

Now we can apply the following rule for the calculation of the power of a power:

$(a^m)^n = a^{m\cdot n}$

So we get:

$7\cdot 80^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

Which can therefore be rewritten as

$7\cdot (2^4\cdot 5)^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

And so, we get

$7\cdot 2 \cdot ( 5)^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

which can be finally rewritten as

$14 ( 5)^{\frac{1}{4}} p^{\frac{1}{4}} q^{\frac{1}{2}} r^{2}$

What is the sum of 1/8 + 5/16 +3/8 = and can I please have step by step

AlekseyPX

Answer:

13/16

Step-by-step explanation:

(1/8) + (5/16) + (3/8) =

The denominator 8 goes into 16 twice so multiply the top and bottom numbers by 2

(1 x 2) + (5/16) + (3 x 2)

(8 x 2) (8 x 2)

2/16 + 5/16 + 6/16 = 13/16

I hope this helps!
