If a normal distribution has a mean of 132 and a standard devistion of 20, what is the value that has a z score of 3.6

nika2105 [10]

z = (x - μ)/σ

Substituting given values, you have

3.6 = (x - 132)/20

(20)(3.6) = x - 132 . . . . multiply by 20

72 + 132 = x . . . . . . . . .add 132

204 = x

The value that has a z-score of 3.6 is 204.

The sum of 6 even integers is 130 what is the 2nd number in the sequence

castortr0y [4]

Answer:

The 2nd number in the sequence is $2\left(\frac{100}{12}\right)+2$

Step-by-step explanation:

Let the six even numbers be 2x,2x+2,2x+4,2x+6,2x+8,2x+10

We are given that The sum of 6 even integers is 130.

So,2x+2x+2+2x+4+2x+6+2x+8+2x+10=130

12x+30=130

12x=100

$x=\frac{100}{12}$

So,the 2nd number in the sequence is $2\left(\frac{100}{12}\right)+2$
