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

Answer:The mean goes up from approximately 80.4 to 82.
Step-by-step explanation:
Before adding 101°, the mean i2:
(58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57)/12 = 80.4
After adding the value 101°, the mean is:
(58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 101)/13 = 82
The mean goes up from approximately 80.4 to 82.

How can you use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3)?
Answer:
To use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3), you can use the following steps:
Rewrite the expression as [5.5+(-2.3)] +(-5.5) + 2.3.
Use the inverse property of addition to rewrite (-5.5) as 5.5, so the expression becomes [5.5+(-2.3)] +(5.5) + 2.3.
Use the inverse property of addition again to rewrite (-2.3) as 2.3, so the expression becomes [5.5+2.3] +(5.5) + 2.3.
Use the associative property of addition to rearrange the terms in the expression, so it becomes 5.5 + 2.3 + 5.5 + 2.3.
Use mental math to add the terms, which gives you a result of 15.8.
Therefore, the sum of [5.5+(-2.3)] +(-5.5 + 2.3) is 15.8.

Answer: Y = 3/8
Step-by-step explanation:
You can either use the rise/run method or subtract 2 points from the line to get the slope. You can do the rise/run method by starting at a point that is on the corner of the square and keep counting how many spaces you have to go until you get to the next even point. This number will be on the bottom, then count up until you get to that even point,this amount of spaces this takes will be on top. Since there are only 2 visible points on this graph,I will use the other method. You can use either the y1-y2/x1-x2 formula or do this
8,3
0,0
8,3
Remember,the y goes on top! Our slope is 3/8,also since the y intercept is the orgin/0,0 we don't need to add it at the end. I hope this helps and wasn't too complicated!
y = 3/8(x) is the equation that represents the proportional relationship in this graph, for y in terms of x.
What is proportional?In mathematics, two sequences of numbers, frequently experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, known as the coefficient of proportionality or proportionality constant.
If corresponding elements in two sequences have a constant product—also known as the coefficient of proportionality—then the two sequences are inversely proportional.
This definition is frequently broadened to include associated varying amounts, also known as variables.
We can see that when y = 1.5, then x = 4
And when y = 3, x = 8
Putting the value in slope form
y - y1 = m(x - x1)
3 - 1.5 = m(8 - 4)
1.5 = m(4)
m = 1.5/4
m = 3/8
Now simply we put the value in y-intercept form
y - 3 = 3/8(x - 8)
y = 3/8(x) - 3 + 3
y = 3/8(x)

A right triangle has one leg with a length of 5 units. The hypotenuse is 30 units long. What is the length of the other leg?
A. 5 Units
B. 25 Units
C. V 875
D. V 375
Answer: C. [tex]\sqrt{875[/tex]
Step-by-step explanation:
use Pythagorean theorem [tex]a^{2}+b^{2}=c^{2}[/tex]
a=5 c=30 solve for b
[tex]25+b^2=900[/tex]
subtract 25 from both sides to get [tex]b^2 =875[/tex]

The equation of line shown in figure is,
⇒ y = x - 4
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (4, 0) and (0, -4).
Now,
Since, The equation of line passes through the points (4, 0) and (0, -4).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 4 - 0) / (0 - 4)
m = - 4 / -4
m = 1
Thus, The equation of line with slope 1 is,
⇒ y - 0 = 1 (x - 4)
⇒ y = x - 4
Therefore, The equation of line is,
⇒ y = x - 4

Step-by-step explanation:
20:4 by dividing 4 from both sides you get the ratio
5 :1
so simplify the other ratios and find one that equals this one
A is already in simplest form 8:1
so it's refused
B 10:2 by dividing 2 from both sides you get the ratio 5 :1
C 15:3 by dividing 3 from both sides you get the ratio 5 :1
so both B and C are correct answers
