A sports medicine major wanted to conduct an experiment to determine if there is a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:
Answer:
Using linear interpolation on the interval [15,23] that would be
9.5 + (22-15)/(23-15) * (11.9-9.5) = 11.6
That is, since 22 is 7/8 of the way from 15 to 23, he should produce a value 7/8 of the way from 9.5 to 11.9
The correct answer is 11.9
I took the test, this is my third time answering this question.
I explained everything but all got erased, anyways the answer is 11.9
Knowing that correlation coefficients have values between -1 and 1 and that the closer the value is to -1 or 1, the stronger the correlation -- which of the following correlation coefficients would represent the strongest correlation?
0.02
0.87
-0.5
-0.97
-0.97 has the strongest correlation. Therefore, option D is the correct answer.
What is the correlation coefficient?The correlation coefficient describes how one variable moves in relation to another. A positive correlation indicates that the two move in the same direction, with a value of 1 denoting a perfect positive correlation. A value of -1 shows a perfect negative, or inverse, correlation, while zero means no linear correlation exists.
Given that, correlation coefficients have values between -1 and 1 and that the closer the value is to -1 or 1, the stronger the correlation
From the options -0.97 is closer to -1
Thus, -0.97 has the strongest correlation
Therefore, option D is the correct answer.

Mitch just finished planting radishes, potatoes, carrots, celery, and peas in his new garden. The garden is a circle whose diameter is 54s. If planted equal regions of each vegetable, what is the area of 's garden that has ? Use 3.14 for pie.
Answer:
Step-by-step explanation:
Note that there are 5 different vegetables, so the area devoted to each is 1/5 of the total garden area:
Remember that the radius of a circle is half its diameter. Here the radius is 54s/2, or 27s.
The area of the entire circle is (pi)(radius)^2, or
(3.14)(27 s)^2, or
2289 s^2
and 1/5 of that is 457.8 s^2
Note 1: It's ' pi, ' not 'pie.'
Note 2: Your ' s ' is not a recognized unit of length. What does your s represent?

A man has $ 10,000 to invest. He invests $ 4000 at 5 % and $ 3500 at 4 %. In order to have a yearly income of $ 500, he must invest the remainder at:
(a) 6 % , (b) 6.1 %, (c) 6.2 %, (d) 6.3 %, (e) 6.4 %
Answer:
Income from $ 4000 at 5 % in one year = $ 4000 of 5 %.
= $ 4000 × 5/100.
= $ 4000 × 0.05.
= $ 200.
Income from $ 3500 at 4 % in one year = $ 3500 of 4 %.
= $ 3500 × 4/100.
= $ 3500 × 0.04.
= $ 140.
Total income from 4000 at 5 % and 3500 at 4 % = $ 200 + $ 140 = $ 340.
Remaining income amount in order to have a yearly income of $ 500 = $ 500 - $ 340.
= $ 160.
Total invested amount = $ 4000 + $ 3500 = $7500.
Remaining invest amount = $ 10000 - $ 7500 = $ 2500.
We know that, Interest = Principal × Rate × Time
Interest = $ 160,
Principal = $ 2500,
Rate = r [we need to find the value of r],
Time = 1 year.
160 = 2500 × r × 1.
160 = 2500r
160/2500 = 2500r/2500 [divide both sides by 2500]
0.064 = r
r = 0.064
Change it to a percent by moving the decimal to the right two places r = 6.4 %
Therefore, he invested the remaining amount $ 2500 at 6.4 % in order to get $ 500 income every year.

20+(5 x 2/5) + 3
Answer:
25.
Step-by-step explanation:
Whenever you attempt to solve an equation with multiple operations, remember this: PEMDAS
ParenthesisExponentiation (exponents)Multiplication/DivisionAddition/Subtraction**THIS IS THE ORDER IN WHICH YOU SHOULD SOLVE EQUATIONS WITH MULTIPLE OPERATIONS.**
First, we solve what is in parenthesis.
20+(5 x 2/5) + 3
5/1 x 2/5 = 10/5 = 2 (simplified)
Then, replace the equation with the answer.
20 + 2 + 3
Secondly, there are no exponents.
There is no multiplication nor division.
However, there is addition.
20 + 2 + 3
20 + 2 = 22
Now, we solve the remaining addition problem.
22 + 3 = 25.
Therefore, 20+(5 x 2/5) + 3 = 25.

Who ever gets this right will get a brainiest and a good rating
Answer:
Radius: 7 cm, Diameter: 14 cm
Step-by-step explanation:
Correct me if I'm wrong, but I understood that 14 cm is the length of the line segment drawn across the circle. We know that the definition of the diameter is "any straight line segment that passes through the center of the circle and whose endpoints lie on the end of each circle", which can be defined as the line that is shown with a length of 14 cm. It is also known that the radius, a line drawn from the center of the circle to an endpoint, is always half of the diameter, which in this case is 14 cm, so the radius would be 7 cm.

Fatimah is driving at 1.5 km in 2 min. What is distance she covered in 2 1/4 h?
Answer:
101.25 km
Step-by-step explanation:
To solve, we need to first find how much she drives in one minute and then multiply that by the number of minutes she drives.
1.5 km = 2 minutes
divide both sides by 2.
1 minute = 0.75 km
2.25 hours = 2.25 * 60 = 135 minutes
Multiply the speed by the time to find distance.
135 * 0.75 = 101.25 km
Thus, she covered 101.25 km in 2 1/4 hours.
