OLga [1]

Answer:

$9486.68

Step-by-step explanation:

The future value of a annuity formula can be used:

FV = P((1+r)^n -1)/r

750000 = P(1.06^30 -1)/0.06

P = 750000(.06)/(1.06^30 -1) = 9486.68

Adam has to contribute $9,486.68 each year to reach his goal.

The claim is that the white blood cell counts of adult females are normally? distributed, with a standard deviation equal to 1.6

antiseptic1488 [7]

From the question, we know the population standard deviation, σ = 1.63, the sample standard deviation, s = 3.07, the sample mean, $\bar{x}=7.43$ and the sample size, n = 38.

The question illustrates a hypothesis chi-square test of variance.

The test statistics for a Chi-squared test of variance is given by
$T=(n-1)\left( \frac{s}{\sigma} \right)^2 \\ \\ =(38-1)\left( \frac{3.07}{1.63} \right)^2 \\ \\ =37(1.883)^2=37(3.5473) \\ \\ =131.25$

Write an expression with a variable m, a coefficient -3, and a constant of 17

Svetlanka [38]

Answer

-3m + 17

Step-by-step explanation:

A coefficient is a number that goes in front of the variable, so -3 would go in front of m. A constant is just a number on it's own, so it would be +17
