On a particular day, the wind added 2 miles per hour to Jaime's rate when she was rowing with the wind and subtracted 2 miles per hour from her rate on her return trip. Jaime found that in the same amount of time she could row 44 miles with the wind, she could go only 36 miles against the wind.What is her normal rowing speed with no wind?

Answers

Answer:20

Step-by-step explanation:

Given Wind speed is 2 mile/hr

Let jamie speed be x km/hr

Also she covered 44 miles with wind in time t

$44=\left ( x+2\right )t$

Against the wind

$36=\left ( x-2\right )t$

divide the two equations

$(44)/(36)=(x+2)/(x-2)$

11x-22=9x+18

x=20 miles/hr

It is 40 because it gives you the even rate inbetween each of them

Is there a relationship between area or perimeter of a rectangle

Answers

Hello,

For a given perimeter (P) there are an infinity of Area (A)
Let's say x the length, and y the wide of the rectangle

P=2(x+y)
A=xy
k=x-y >=0

As (x+y)²-4xy=(x-y)²: A²-4P=k² or P=(A²-k²)/4
In primus, you will find a graph (abacus) giving P for a A and k given.
Negative Area or P are excluded.(just remind the first quadrant, A>=0 and P>=0)

A researcher records the time (in seconds) that participants arrive late for a scheduled research study. Assuming these data are normally distributed, which measure of central tendency is most appropriate to describe these data?

Answers

Answer:MEAN

Step-by-step explanation:Mean is a measure of central tendency it is sometimes referred to as a average of a set of numbers.The mean can also be described as the central value of a discrete set of values or numbers, the formula for Arithmetic mean is the sum of the values or number divided by the number of values or outcome.

Normal distribution is a statistical term which describes a set of values or numbers whose symmetric, unimodal, and asymptotic, and the mean, median, and mode are all equal.

Lorenzo is a salesman whose base pay plus commissions amounted to $53,393 last year. If his base pay was $24,650 and he made $87,100 in sales last year, what was his rate of commission?A. 33%

B. 28%

C. 46%

D. 61%

Answers

Since, a salesman whose base pay plus commissions amounted to $53,393 last year. If his base pay was $24,650 and he made $87,100 in sales last year. We have to evaluate the rate of commission.

Let the rate of commission be 'r%'.

Therefore,

24,650 + (87,100 of r%) = 53,393

$24,650 +(87,100 * (r)/(100))= 53,393$

$(87,100 * (r)/(100))= 53,393-24,650$

$(87,100 * (r)/(100))= 28,743$

$87,100 * {r}= 28,743 * 100$

$87,100 * {r}= 2874300$

${r}= (2874300)/(87100)$

r = 33%

Therefore, the rate of commission is 33%.

33%

What does it mean if the probability is 20% that a spinner will stop in a red section? A.
There is one chance in 5 that the spinner will stop in a red section.

B.
It is 20 times more likely that the spinner will stop in a red section than any other section.

C.
If the spinner is spun 100 times it is certain that it will stop in the red section exactly 20 times.

D.
There is one chance in 20 that the spinner will stop in a red section.

Answers

20% = 20/100 = 1/5

Hence, there is one chance in five that the spinner will stop in a red section.

Find the slope of the line through each pair Of points.1. (1,5) and (2,8)
2. (3,1) and (3,-1)

Answers

In order to find the slope between a set of points you must plug the points into the point slope formula ; ( y2-y1 / x2-x1 )

Once you plug that in you should get the final answers of

1. slope = 3

2. slope = -2/0 which is undefined which means this slope would be part of a vertical line
