Answer:
The standard deviation of the residuals calculates how much the data points spread around the regression line. The result is used to measure the error of the regression line's predictability.
Step-by-step explanation:
How do you find the standard deviation around the regression line?STDEV. S(errors) = (SQRT(1 minus R-squared)) x STDEV. S(Y). So, if you know the standard deviation of Y, and you know the correlation between Y and X, you can figure out what the standard deviation of the errors would be be if you regressed Y on X.
What does standard deviation tell you?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Solve the inequality and graph the solution. 2x < 10. Create your own number line to graph the solution.
Answer:
2x<10 is basically x<5
Step-by-step explanation:
You divide both sides by 2 to isolate x and since 2 is not negative it doesn't change the sign.
What is UT?
TUV is a right angle triangle. An angle U is right angle. The length of TV is 17 and the length of UV 8
In the right triangle given, the length of UT using the Pythagorean theorem is: UT = 15.
What is the Pythagorean Theorem?Pythagorean theorem is given as: c² = a² + b², where a and b are the legs of a right triangle, and c is the hypotenuse (the side opposite the right angle).
Given:
c = TV = 17
a = UT = ?
b = UV = 8
Plug in the values
17² = UT² + 8²
UT = √(17² - 8²)
UT = 15.
Thus, in the right triangle given, the length of UT using the Pythagorean theorem is: UT = 15.

Chris made a batter with ⅞ cup of flour, ⅝ cup of milk, ⅜ cup of butter and ⅜ cup of sugar. How many cups of batter did Chris make?
Answer:
2(1/4) cups 2 cups and a quarter
Step-by-step explanation:
⅞ + ⅝ + ⅜ + ⅜ = 18/8
= 2 (2/8) = 2(1/4)
There are 9/4 cups of batter did Chris make.
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
Chris made a batter with ⅞ cup of flour, ⅝ cup of milk, ⅜ cup of butter and ⅜ cup of sugar.
Hence, Number of cups of batter did Chris make are,
⇒ 7/8 + 5/8 + 3/8 + 3/8
⇒ (7 + 5 + 3 + 3) / 8
⇒ 18/8
⇒ 9/4

A company produces computer batteries. Everyday, the company produces exactly 500 batteries. To keep track of how many batteries are defective, a
worker tested a box of batteries. The results are in the table below.
Working Batteries Defective Batteries Total

20
Using these results, about how many batteries each day are defective?
O 3
O 25
O75
O425
Using the binomial distribution, it is found that about 75 batteries each day are defective.
For each battery, there are only two possible outcomes, either it is defective, or it is not. The probability of a battery being defective is independent of any other battery, hence the binomial distribution is used to solve this question.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
In this problem:
3 out of 20 batteries are defective, hence p = 3/20 = 0.15.Each day, 500 batteries are produced, hence n = 500.Then:
[tex]E(X) = np = 500(0.15) = 75[/tex]
About 75 batteries each day are defective.

To know while working with inequality equations:
- When multiplying or dividing by a negative, you want to flip the direction of the inequality sign. < becomes >, etc
- When graphing, if it is only less/greater than (< or >) the dot will be open
- When graphing, if it is less/greater than and equal too (≤ or ≥) the dot will be closed
- Then, if the x value is on the left side, the arrow will go in the direction of the inequality sign
[3] Divide both sides by -4, flip the sign
-4x ≥ -36
x ≤ 9
[4] Divide both sides by -0.4, flip the sign, and then I flipped the equation to make it easy to graph
3 > -0.4x
-7.5 < x
x > -7.5
[5] Divide both sides by -2.2, flip the sign
-2.2x ≤ -6.6
x ≥ 3
[6] Multiply both sides by -8, flip the sign

Step-by-step explanation:
Conventionally, milk is pasteurized, or heated at high temperatures to kill harmful germs, at roughly 160 degrees Fahrenheit for 15 seconds. While pasteurization kills most germs, it does not wipe out bacterial spores, the dormant versions of the germs, which are extremely resistant to any form of destruction.

3) An $1,000 investment is made in a trust fund at an annual percentage rate of 12%,
compounded yearly. How long will it take the investment to reach $2,000?
We need to find the interest rate in order to solve this problem:
.12/12 = (.01)
The number of years is unknown. T represents time in the following formula:
1000 (initial investment)
2000 (balance after t years from investment)
[tex]$1000 (1 + .01)^{12t}[/tex]=$2000
In order to isolate the exponential term, both sides must be divided by 1000.
[tex](1+.01)^{12t}[/tex]=2
By using natural logarithm:
[tex]Ln(1+.01)^{12t} =Ln2\\(12t)Ln(1+.01)=Ln2\\[/tex]
By dividing both sides of the equation by [tex](12)Ln(1+.01)[/tex]
[tex]t=\frac{Ln(2)}{(12)Ln(1+.01)} =5.805yrs[/tex]

One day at football practice, Darrell, the kicker, punted the ball so that its height in feet above the ground was given by the following function, where t is the number of seconds since the ball was punted.
[tex]h(t)=-16t^{2} +75[/tex]
When will the football be 81 feet high?
When the football is 81 feet high, it will be √ 3 / 8 seconds
FunctionFunction relates input to output. Therefore,
h(t) = - 16t² + 75Therefore,
t = number of seconds
h(t) = - 16t² + 75
h(t) = 81 ft
Therefore,
81 = - 16t² + 75
- 16t² = 81 - 75
- 16t² = 6
divide both sides by -16
t² = 6 / -16
t² = - 3 / 8
square root both sides
t = √ 3 / 8 seconds
