The first one on the list can be any one of 25.

For each of those . . . . .

The 2nd one on the list can be any one of the other 14.

For each of those . . . . .

The 3rd one can be any one of the other 13.

.

.

.

The total number of different ways to list them is "15 factorial" .

That's written as  " 15 ! ".  It means

15 · 14 ·  13 ·  12 ·  11 ·  10 ·  9 ·  8 ·  7 ·  6 ·  5 ·  4 ·  3 ·  2 ·  1

and it's a big number.

15 !  = 1,307,674,368,000 (rounded to the nearest thousand).

Let ∠Q be an acute angle such that tanQ=0.04. Use a calculator to approximate the measure of ∠Q to the nearest tenth of a degree
Digiron [165]

We have been given that ∠Q is an acute angle such that \text{tan}(Q)=0.04. We are asked to find the measure of angle Q to nearest tenth of a degree.

We will use arctan to solve for measure of angle Q as:

Q=\text{tan}^{-1}(0.04)

Now we will use calculator to solve for Q as:

Q=2.290610042639^{\circ}

Upon rounding to nearest tenth of degree, we will get:

Q=2.3^{\circ}

Therefore, measure of angle Q is approximately 2.3 degrees.

Find the coefficient of correlation between and X and Y if covariance between X and Y is 15 and the variance of X and Y are resp
IRINA_888 [86]

Answer:

0.95

Step-by-step explanation:

Correlation \ coefficient \   (r) = \dfrac{covaraince \  between \ X \ and \ Y }{SD_X \times SD_Y }

Correlation \ coefficient \   (r) = \dfrac{15 }{10^{1/2} \times 25^{1/2} }

Correlation \ coefficient \   (r) = \dfrac{15 }{3.162 \times 5 }

Correlation \ coefficient \   (r) = \dfrac{15 }{15.81 }

Correlation \ coefficient \   (r) \simeq 0.95
