The U.S. Fish and Wildlife Service reported that the mean length of six-year-old rainbow trout in the Arolik River in Alaska is

Anettt [7]

Answer:

The size limit for 15% of of six-year-old trout is 438.52 mm.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 481 millimeters

Standard Deviation, σ = 41 millimeters

We are given that the distribution of mean length of six-year-old rainbow trout is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.15

$P( X < x) = P( z < \displaystyle\frac{x - 481}{41})=0.15$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 481}{41} = -1.036\\\\x = 438.524$

Thus, the size limit for 15% of of six-year-old trout is 438.52 mm.

What is the value of c so that -10 and 10 are both solutions of x2 -c=70?

olga nikolaevna [1]

Answer:

c = 30

Step-by-step explanation:

since:

${(10)}^{2} = { (- 10)}^{2}$

once we find a c value for 10, we know that it will work for - 10 as well

${x}^{2} - c = 70$

we can sub in 10 to get

${10}^{2} - c = 70 \\ c = 100 - 70 \\ c = 30$

Use the distributive property two different ways to find the product of 127 and 32

cricket20 [7]

127 = 100 +27
32 = 30 +2
so 127 x 32 = (100 + 27) x (30+2) = (100x30) + (100x2) + (27x30) +(27x2)
= 3000+200+810+54 = 4064

second way:

127 = 100 + 27
127 x 32 = (100+27) x 32 = (100x 32) + ( 27x32) = 3200 + 864 = 4064
