(URGENT!!!) Can someone help me with this? For part a), would the equation A=200(15)^m=395 work? In part b), can't I just factor

the number of months into the equation I wrote in part a)? In part c) the rate of change is 4 months, right? And in part d) I would use the same 4 month rate of change to find the answer to that, wouldn't I? If someone can check my answers/correct me where I'm wrong, I'd really appreciate it! :)

A.) 200+15m=395. This is because the initial price is 200, and after that she will add $15/month. The equation you chose would be exponential, meaning the rate would increase as time passed, which is not the case. Instead, the rate is constant, and the only think that changes is m, the number of months.

b.) I believe it will be easier to answer with ^this equation.

c.) The rate of change would be 15, since the rate is increasing monthly by $15.

d.) Once you solve 209+15m=495, you'll have the answer.

About one-fifth of the population of a town has blue eyes. About two-sevenths of the population has brown eyes. What is the prob
mihalych1998 [28]

Answer:

Option C, 1/35

Step-by-step explanation:

Given

Proportion of town that has blue eyes = 1/5 = 0.2

Proportion of town that has brown eyes = 1/7

The probability of choosing either a blue eye or a brown eye person is

Probability of blue eye individual * Probability of brown eye individual

= 1/5 * 1/7 = 1/35

Hence, option C is correct

two coplanar lines that are perpendicular to the same line are parallel. a) always b) sometimes c) never
sergeinik [125]

<u>Answer:</u>

Two co planar lines that are perpendicular to the same line are always PARALLEL. So option A is correct.

<u>Explanation:</u>

Given:

  • Two lines are coplanar.
  • They are perpendicular to the same line  

To find:

whether they are parallel or not and choose the correct option from the given options.

Solution:

Now, we know that, slopes of perpendicular lines is -1

Then, \text{{slope of 1st line}}\times \text{{slope of perpendicular line}} = -1

\text{{slope of perpendicular line}} =\frac{- 1}{\text{{1st line slope}}}

similarly

\text{{slope of 2st line}}\times \text{{slope of perpendicular line}} = -1

\text{{slope of perpendicular line}} =\frac{- 1}{\text{{2st line slope}}}

Now, as both lines are perpendicular to same line, then, we have to equate above both of them.

Then, \frac{- 1}{\text{{1st line slope}}}= \frac{-1 }{\text{{2nd line slope}}}

1st line slope = 2nd line slope

Here, slopes of two lines are equal.

Hence, Two coplanar lines that are perpendicular to the same line are always parallel. So option A is correct.

Answer: A simple random sample

Step-by-step explanation:

Simple random sampling refers to the probability sampling whereby the researcher chooses selects a subset of participants from the population.

In this case, every member has an equal chance of being chosen. Since anyone could mail in a response or use the paper's Web site to respond, then it's a simple random sampling.

4x + 8y = 32 <br> 5x + 10y = 40
VladimirAG [237]
Solve for 4x + 8y = 32
x = 8 - 2y
Substitute x= 8 - 2y into 5x + 10y = 40
40 = 40
Since 40 = 40 is redundant information, this is dependent system
