Perpendicular slopes have a product of -1, thus $\bf \cfrac{1}{2}\cdot \cfrac{d}{3}=-1$

solve for "d"

Perpendicular lines have slopes that multiply to get -1
so

1/2 times d/3=-1
d/6=-1
times both sides by 6
d=-6

Elanso [62]

Answer: 0.0885

Step-by-step explanation:

Given : According to a recent Catalyst Census, 16% of executive officers were women with companies that have company headquarters in the Midwest.

i.e. p= 0.16

Sample size : n= 154

Now, the probability that more than 20% of this sample is comprised of female employees is given by :-

$P(p>0.20)=P(z>\dfrac{0.20-0.16}{\sqrt{\dfrac{0.16(1-0.16)}{154}}})$

[∵ $z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$ ]

$=P(z>1.35)\approx1-P(z\leq1.35)=1-0.9115=0.0885$ [Using the standard z-value table]

Hence, the required probability = 0.0885

Sergio039 [100]

Answer:

(17+11)/(-9-5)= 28/-14= -2 the slope

y + 11 = -2(x - 5)

y + 11= -2x + 10

y = -2x - 1 the equation
