A line segment has an endpoint at (-4,10) and a midpoint at (-8,0). Find the other endpoint.

Evgen [1.6K]

Answer:

(-12, -10)

Step-by-step explanation:

Midpoint M is the average of endpoints A and B:

M = (A +B)/2

2M = A + B . . . . . . multiply by 2; next, subtract A

B = 2M - A . . . . . . the missing endpoint can be found this way

B = 2(-8, 0) -(-4, 10) = (2(-8)+4, 2(0)-10) = (-12, -10)

Dr. V.R. Bencivenga and Dr. Stephen Donald Economics 329 HOMEWORK QUESTION - Belief in global warming In a large city a certain

Dmitry [639]

Answer: d. 1068

Step-by-step explanation:

Let p be the proportion of adults believe that global warming is a liberal hoax designed to hurt oil companies.

Given : You plan to take a survey of n adults to "estimate" this proportion. You want to be able to say that your estimate is within three percentage points (i.e., within 0.03) of the true proportion, with 0.95 probability.

Margin of error : E= 0.03

We know that the z-value for 95% confidence = $z_c=1.96$

Since the prior proportion of adults believe that global warming is a liberal hoax designed to hurt oil companies.

We assume p = 0.5

Then by Central Limit Theorem , the required sample size would be :

$n=p(1-p)(\dfrac{z_{c}}{E})^2$

$\Rightarrow\ n=0.5(1-0.5)(\dfrac{1.96}{0.03})^2$

Simply , we get

$n=1067.11111111\approx1068$ [Rounded to the next whole number.]

Hence, the smallest sample size that guarantees that you would obtain a satisfactory estimate =1068

16 3/4 hours in two days plan to work 12 3/4 hour the next two days. How many hours will u total on your time sheet for these 4

sergiy2304 [10]

let's firstly convert the mixed fractions to improper fractions and then add up all four days.

$\bf \stackrel{mixed}{16\frac{3}{4}}\implies \cfrac{16\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{67}{4}}~\hfill \stackrel{mixed}{12\frac{3}{4}}\implies \cfrac{12\cdot 4+3}{4}\implies \cfrac{47}{4} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{all 4 days summed up}}{\cfrac{67}{4}+\cfrac{47}{4}}\implies \cfrac{67+47}{4}\implies \cfrac{114}{4}\implies \cfrac{57}{2}\implies 28\frac{1}{2}$
