Let's say you wanted to add 2 and 7
One way is you start at 2 on the number line, then move 7 units to the right until you land on 9. This visually shows 2+7 = 9.
Or you could start at 7 and move 2 units to the right, and you'll end up at 9 as well. You can think of it like 2+7 and 7+2 are the same thing.

Answers
The Bonferroni correction is the post hoc test calculated by dividing the desired level of significance by the number of comparisons. This test is used to control the Familywise Error Rate, thereby reducing the likelihood of a Type I error.
Explanation:The post hoc test that is calculated by dividing the desired level of significance, commonly denoted as 'a', by the number of comparisons being made is known as the Bonferroni correction. This adjustment method is designed to control the Familywise Error Rate (FWER), this is, the probability of making one or more Type I errors (rejecting the null hypothesis when it is true) in a set of hypotheses.
For example, if you set your 'desired a level' (also known as the level of significance of the test) at 0.05 and you were making five comparisons, the Bonferroni correction would deflate your 'a level' to 0.05/5 = 0.01.
Therefore, you would only reject a null hypothesis if the p-value for that comparison was less than 0.01, rather than the 0.05 that you originally specified. The effect of this correction is that it makes it harder to reject individual null hypotheses, making the test more conservative and reducing the likelihood of a Type I error.

A $18.00 haircut cost $25.63 after tax and tip. What percent was the tax and tip combined? If needed, round the answer to the nearest tenth
Answers
Answer:
42.3 percent was the tax and tip combined.
Step-by-step explanation:
Given : A $18.00 haircut cost $25.63 after tax and tip.
To find : What percent was the tax and tip combined?
Solution :
Using sales tax formula,
[tex]\text{Sales tax}=\text{Rate}\times \text{Original price}[/tex]
Original price = $18
After tax and tip cost is $25.63
Sales tax = After tax and tip cost - Original cost
Sales tax = $25.63 - $18
Sales tax = $7.63
Substitute the values,
[tex]7.63=\text{Rate}\times 18[/tex]
[tex]\text{Rate}=\frac{7.63}{18}[/tex]
[tex]\text{Rate}=0.423[/tex]
Into percentage,
[tex]\%\text{Rate}=0.423\times 100=42.3\%[/tex]
Therefore, 42.3% was the tax and tip combined.

A store is having a sale on jelly beans and trail mix. For 6 pounds of jelly beans and 2 pounds of trail mix, the total cost is $20. For 3 pounds of jelly beans and 5 pounds of trail mix, the total cost is $23. Find the cost for each pound of jelly beans and each pound of trail mix.
Answers
Answer:
Jelly beans are $2.25/pound, trail mix $3,25/pound
Step-by-step explanation:
Let’s say that the cost of a pound of jelly beans is x, and that the cost of a pound of trail mix is y.
We can then say that 6 pounds of jelly beans + 2 pounds of trail mix, or 6x+2y, equals 20.
Next, 3x+5y=23, and we have
6x+2y=20
3x+5y=23
We can multiply the whole second equation by -2 and add it to the first one to get rid of the x, so -8y=-26. Divide both sides by -8, and a pound of trail mix, or y, is 26/8, or $3.25. Plugging this back into the first equation, we get that
6x+2(26/8)=20, so (20-2(26/8))/6=x=2.25, or the cost of one pound of jelly beans
To solve for the cost per pound of jelly beans and trail mix, create and solve a system of algebraic equations using the provided information. Multiply and subtract equations as needed to eliminate one variable and solve for the other, then back-substitute to find the second value.
Explanation:The question involves a system of two equations based on the prices of jelly beans and trail mix. We can use algebra to solve for the cost per pound of each. Let's denote the cost per pound of jelly beans as j and the cost per pound of trail mix as t.
The two equations based on the given information are:
6j + 2t = $203j + 5t = $23To solve these equations, we can use either substitution or elimination. Let's use the elimination method:
Multiply the first equation by 3 and the second by 2.This gives us 18j + 6t = $60 and 6j + 10t = $46.Subtracting the second equation from the first gives us 12j - 4t = $14.Multiply the second original equation by 2, yielding 6j + 10t = $46.Now take the modified first equation (12j - 4t = $14) and divide by 2 to simplify, getting 6j - 2t = $7.Adding this to the modified second equation results in 12j + 8t = $53.We can now solve for one variable. For instance, from 6j - 2t = $7, we can express t as (6j - $7)/2.Substitute this expression for t in one of the original equations to find j.Once j is found, use it to calculate t from either equation.After solving, we will find the costs per pound for jelly beans and trail mix.

Answer:
f(6) = 18
Step-by-step explanation:
So we are given that f(x) = x² ÷ 3 + x, and we are trying to find f(6).
To find f(n) for a function f(x), we plug in n for x into f(x).
To find (6) for f(x) = x² ÷ 3 + x, we plug in 6 for x into f(x).

When the number of hours increases, the number of miles increases. When the number of hours decreases, the number of miles increases. When the number of hours decreases, the number of miles stays the same.
Answers
Answer:
The answer to this question is B, I've taken this test
Step-by-step explanation:
When the number of hours increases, the number of miles increases
When the number of hours increases, the number of miles increases.
What is Speed?The rate of change of position of an object in any direction is called as Speed.
As the number of hours changes then the number of miles traveled by the car will be also changed.
Such that number of miles traveled by the car increases then the number of hours also increases.
The reason behind this is, the car is traveling at a constant speed of 65 miles per hour, which means it travels longer as the distance is more.
If the number of hours decreases, the number of miles traveled by the car will also decrease by converse, since the car has had little time to cover distance.
Therefore, When the number of hours increases, the number of miles increases.

On the number line, a bug A is moving in the positive direction from the point 0, and a bug Bis moving in the negative direction from the point 0. The speeds of both bugs are constant. Both leave 0 at the same time, and three seconds later A has reached 18 and B has reached –15.
When will A and B be 220 units apart?
Answers
Answer:
20 seconds
Step-by-step explanation:
The speed of A is:
sA = 18 units / 3 seconds = 6 units/second
The speed of B is:
sB = -15 units / 3 seconds = -5 units/second
The relative speed is:
s = sA − sB
s = 6 units/second − (-5 units/second)
s = 11 units/second
The time for the distance between them to be 220 units is:
220 units = 11 units/second × t
t = 20 seconds

-81 x -2= 162
you basically want to end up with a negative number so the -2 will change it back into a positive value.
hope this helps :D
It would be C. An odd number of factors were negative.
We can start off by eliminating A. If all of the numbers were positive: 1 x 2 x 3 x 4 = 24, and 24 ÷ - 2 = -12, since you are still dividing a positive by a negative.
With B- Both problems have you multiplying negative numbers by each other until they cancel out. In B, if you multiply -1 x -2, the negatives cancel out and you get 2. and then, -3 x -4 = 12, negatives cancelling out again, and your last two numbers are going to be positive, so once you multiply them together and multiply by a negative your result will be negative.
D is similar to B. Since we have 4 numbers, two will have to be negative. -1 x 2 x -3 x 4 = 24 since the two negatives will cancel each other out.
the answer is C. An odd number of factors were negative then, since if we have 1 or 3 negative numbers, there will be one left over after the others cancel each other out.

Omar buys five shirts for $22 each, three pairs of pants for $50 each, and six ties for $17 each. What is the mean amount that he spent per article of clothing?
Answers
To calculate the mean amount spent per article of clothing, add the total cost of all the items and divide by the number of articles purchased. Omar's mean spending per article comes out to approximately $25.86.
To find the mean amount spent per article of clothing, we first need to calculate the total cost of all the items Omar bought and then divide that total by the number of articles he purchased. Omar bought five shirts at $22 each, three pairs of pants at $50 each, and six ties at $17 each.
First, calculate the total cost for each type of clothing:
Shirts: 5 shirts times $22 = $110
Pants: 3 pairs times $50 = $150
Ties: 6 ties times $17 = $102
Next, add all these amounts to get the total cost:
Total cost = $110 + $150 + $102 = $362
Now, count the total number of articles:
Total articles = 5 shirts + 3 pairs of pants + 6 ties = 14 articles
Finally, divide the total cost by the total number of articles to find the mean cost:
Mean cost = Total cost \/ Total articles = $362 \/ 14 ≈ $25.86
Therefore, the mean amount Omar spent per article of clothing is approximately $25.86.

Find the lateral and total surface area of the prism.
lateral SA:_____
Total SA:_____
Answers
Lateral surface area of the prism = 920 in²
Total surface area of the prism = 1180 in²
Solution:
Length of the prism = 13 in
Width of the prism = 10 in
Height of the prism = 20 in
Lateral surface area of the prism = 2(l + w)h
= 2(13 + 10) × 20
= 2(23) × 20
= 920 in²
Lateral surface area of the prism = 920 in²
Total surface area of the prism = Lateral area + 2lw
= 920 + 2 × 13 × 10
= 920 + 260
Total surface area of the prism = 1180 in²
Hence Lateral surface area of the prism = 920 in²
Total surface area of the prism = 1180 in²
The lateral surface area of a prism is found by multiplying the perimeter of the base shape by the height of the prism. The total surface area is the lateral surface area plus twice the area of the base shape. The formulas are applied differently depending on the base shape of the prism.
Explanation:To find the lateral surface area (SA) and the total surface area of the prism, we need to apply the correct formulas. The lateral SA for a prism is the perimeter of the base shape times the height. The total SA is the lateral SA plus twice the area of the base shape.
For example, let's use a rectangular prism with dimensions: length (l)=5 cm, width (w)=3 cm, and height (h)=10 cm. The lateral SA = 2*h*(l+w) = 2*10*(5+3) = 160 sq cm. The base shape has area = l*w, so total SA = 2*lw + lateral SA = 2*(5*3) + 160 = 30*2 + 160 = 220 sq cm.
In similar manner, the formula can be adjusted depending upon the base shape of the prism like for a triangular prism, square prism, etc.

I need help to find the slope in this table. Ignore the writing please. THANK YOU SO MUCH.
Answers
The slope value for the given table is 13.
Step-by-step explanation:
Step 1:
[tex]slope = \frac{y2-y1}{x2-x1}[/tex], where [tex]x1,y1[/tex] are the first set of values and [tex]x2,y2[/tex] are the second set of values.
The given table has three sets of values so we can calculate two values of the slope.
Step 2:
To calculate the first slope value, we use the first and second sets of values.
The values are [tex]x1=3,y1=39[/tex] and [tex]x2=5,y2=65[/tex].
The slope for the given values is;
[tex]slope = \frac{65-39}{5-3}[/tex] = [tex]\frac{26}{2}[/tex] = [tex]13.[/tex]
The slope for the first set of given values is 13.
Step 3:
To calculate the second slope value, we use the second and third sets of values.
The values are [tex]x1=5,y1=65[/tex] and [tex]x2=8,y2=104[/tex].
The slope for the given values is;
[tex]slope = \frac{104-65}{8-5}[/tex] = [tex]\frac{39}{3}[/tex] = [tex]13.[/tex]
The slope for the second set of given values is 13.
So the slope for the given set of values is 13.
indicate the standard form the equatin of the line passing through the given pints E(-2,2) F(5,1)
Answers
Answer:
y = -x/7 + 12/7
Step-by-step explanation:
We are requested to find the standard equation of a line
We are given two points
E and F
E ( -2 , 2)
F ( 5 ,1 )
Step 1: find the slope
m = y_2 - y_1 / x_2 - x_1
x_1 = -2
y_1 =2
x_2 = 5
y_2 = 1
Inserting the values
m = 1 - 2 / 5 - (-2)
m = 1 -2 / 5 + 2
= -1 / 7
Slope = -1/7
Step 2: using the point slope form
y - y_1 = m( x - x_1)
Using point ( 5, 1)
x_1 = 5
y_1 = 1
m = -1/7
Insert the values
y - 1 = -1/7(x - 5)
y - 1 = -1(x - 5)/7
Open the bracket with -1
y - 1 =( -x + 5) / 7
following the equation of a line
y = mx + C
y = (-x + 5)/7 + 1
LCM = 7
y = (-x + 5+ 7) / 7
y = (-x + 12)/7
We can still separate
y = -x/7 + 12/7
The standard equation of a line is
y = -x/7 + 12/7
