1 answer:
SVETLANKA909090 [29]3 years ago
5 0

Answer: C

Step-by-step explanation:

We are given the information that:

  1. The airplane is at 50,000 feet
  2. It descends 2,500 feet in 1 minute
  3. x = minutes

For  ease of solving this question, let's set the number of minutes (x) to 1.

  • In one minute, we know the plane will drop to 47,500 feet. (50,000 - 2,500(x))

There are multiple ways to write this equation bu shifting around negative and positive values. Another way to write this equation would be (-2,500(x) + 50,000). That would be choice C.

Try it out~

(-2,500(x) + 50,000)\\ (-2,500(1) + 50,000)\\ (-2,500 + 50,000)\\47,500

It works, so our answer is C.

Find m angle d for m angle b = 65<br> The figure is not drawn to scale
Aleksandr [31]

Answer:

Denote O as center of circle, draw OA, OC.

As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):

=> AOC + D = 180

Moreover, angle  AOC = 2 x angle B = 2 x 65 = 130

=> D = 180 - 130 = 50 deg

Hope this helps!

Heather is a student in a class that has been asked to conduct a hypothesis test for a population proportion. The null and alter
Rasek [7]

Answer:

Alan = reject H0

Bill = cannot say

Step-by-step explanation:

Given that Heather is a student in a class that has been asked to conduct a hypothesis test for a population proportion.

H0: p = 0.5 \\Ha: p ≠ 0.5

(two tailed test at 5% significance level)

Since she rejects null hypothesis p value should have been less than 0.05

when p value <0.05, it is definitely less than 0.10

So at 1% level of significance also the null hypothesis would be rejected.

So Alan also would get the same result as to reject the H0

But about Bill since Bill uses 0.01, we cannot definitely say that p value is less than or greater than 0.01

All we know is that p is less than 0.05

Hence it is impossible to tell from the information for Bill

AB is perpendicular to CD. If the slope of AB is 2/5, what is the slope of CD?​
alekssr [168]

Given a slope m, the slope m' of a line perpendicular to m is the opposite of the inverse of m

In other words:

mm' = -1 \iff m' = -\dfrac{1}{m}

So, the slope of CD is -5/2.
