choose the slope-intercept equation of the line that passes through the point (4, -6) and is parallel to y = - 1/2x 5. a. y = -2

nexus9112 [7]

Parallel lines has equal slopes. Hence slope of line = -1/2
equation of line is (y - y1) = -1/2(x - x1)
y - (-6) = -1/2(x - 4)
y + 6 = -1/2x + 2
y = -1/2x + 2 - 6
y = -1/2x - 4

Multiply and simplify.

katrin2010 [14]

ANSWER

$8 {x}^{5} {y}^{7} {z}^{2}$

EXPLANATION

The given expression is

$2 {x}^{2} {y}^{3} {z}^{2} \times 4x {y}^{4} {x}^{2}$

We multiply out to obtain,

$= 2 \times 4 \times {x}^{2} \times x \times {x}^{2} \times {y}^{3} \times {y}^{4} \times {z}^{2}$

Recall that,

${a}^{m} \times {a}^{n} = {a}^{m + n}$

We apply this rule to obtain,

$= 8 {x}^{2 + 1 + 2} {y}^{3 + 4} {z}^{2}$

This simplifies to
$= 8 {x}^{5} {y}^{7} {z}^{2}$

Replacement times for CD players are normally distributed

slavikrds [6]

Answer:

0.04

Step-by-step explanation:

X~N(μ=14.2; σ=0.9), a=7

$P(X>7)=1-P(X\leq 7)$

$P(0\leq X\leq a)=P(\frac{0-\mu}{\sigma} \leq \frac{X-\mu}{\sigma}\leq \frac{a-\mu}{\sigma}), Z= \frac{X-\mu}{\sigma}=P(0\leq X\leq a)=P(\frac{0-\mu}{\sigma} \leq \frac{X-\mu}{\sigma}\leq \frac{a-\mu}{\sigma}), Z= \frac{X-\mu}{\sigma}$

$P(0\leq X\leq 7) = P(\frac{0-5.5}{1.5} \leq Z\leq \frac{7-5.5}{1.5}) = \Phi(1.66)-\Phi(-3.66) = \Phi(1.66) -(1-\Phi(3.66)) = 0.95-(1-0.99)=0.96$

P(X>7)=1-0.96=0.04
