7. What is the slope of the line that passes through the points (14, -18) and (5, -12)?

worty [1.4K]

Answer:

slope = $-\frac{2}{3}$

Step-by-step explanation:

Use the slope formula $m = \frac{y_2-y_1}{x_2-x_1}$ to find the slope, or $m$ . The $x_1$ and $y_1$ represent the x and y values of one point, and the $x_2$ and $y_2$ represent the x and y values of another point. So, substitute the x and y values of the points (14, -18) and (5, -12) into the formula and solve:

$m = \frac{(-12)-(-18)}{(5)-(14)}\\m = \frac{-12+18}{5-14}\\m = \frac{6}{-9} \\m = -\frac{2}{3}$

Thus, the slope is $-\frac{2}{3}$ .

If X is a normal random variable with parameters µ = 10 and σ 2 = 36, compute

alex41 [277]

Answer:

Step-by-step explanation:

Given that X is a normal random variable with parameters µ = 10 and σ 2 = 36,

X is N(10, 6)

Or z = $\frac{x-10}{6}$

is N(0,1)

a) P(X > 5),

= $P(Z>-0.8333)\\=0.7977$

(b) P(4 < X < 16),

= $P(|z|$

(c) P(X < 8),

= $P(Z$

(d) P(X < 20),

= $P(Z$

(e) P(X > 16).

=P(Z>-0.6667)

= 0.2524
