Answer:
CLASS FREQUENCIES RELATIVE FREQUENCIES
A 60 0.5
B 12 0.1
C 48 0.4
TOTAL 120 1
Step-by-step explanation:
Given that;
the frequencies of there alternatives are;
Frequency A = 60
Frequency B = 12
Frequency C = 48
Total = 60 + 12 + 48 = 120
Now to determine our relative frequency, we divide each frequency by the total sum of the given frequencies;
Relative Frequency A = Frequency A / total = 60 / 120 = 0.5
Relative Frequency B = Frequency B / total = 12 / 120 = 0.1
Relative Frequency C = Frequency C / total = 48 / 120 = 0.4
therefore;
CLASS FREQUENCIES RELATIVE FREQUENCIES
A 60 0.5
B 12 0.1
C 48 0.4
TOTAL 120 1

How many ways can Patricia choose 4 pizza toppings from a menu of 8 toppings if each topping can only be chosen once
Answer: 70
======================================================
Explanation:
Consider we have four slots A, B, C, D.
We have 8 choices for slot A, 7 for B, 6 for C, and 5 for D.
We count down because each time we can't reuse whatever topping was picked earlier.
Multiplying out those values gives: 8*7*6*5 = 1680
There are 1680 permutations. This would be the answer if order mattered, but it doesn't matter.
Since order doesn't matter, we have to divide by 4! = 4*3*2*1 = 24. This is the number of ways to arrange any group of 4 items.
We get 1680/24 = 70 as the final answer
--------------------
Another way to get the answer is to apply the nCr combination formula
[tex]_nC_r = \frac{n!}{r!*(n-r)!}[/tex]
with n = 8 and r = 4.
Another alternative is to use Pascal's Triangle. You would look in the row that starts with 1,8,... and count out 5 slots (because r starts at r = 0) to arrive at 70.

I can answer the slopes
Answer:
1. would have a slope of 2
2. would have a slope of -1.66
3.would have a slope of 0
4. would have a slope of -13
Step-by-step explanation:
(Y2 - Y1) / (X2 -X1)
1. (9-5) / (4-2) = 4 / 2 =2
2. (-5-5) / (3 - -3) = -10 / 6 = 1.66
3. (2 - 2) / (5 - -4) = 0 / 9 = 0
4. (-7 - 6) / (3 - 3) = -13 / 0 = -13

Rob is 7 years older than James. Kate is 2 years younger than James. If the sum of their ages is 116, how old are each of the siblings?
Answer:
James is 37, Rob is 44, and Kate is 35
Step-by-step explanation:
Set up an equation where x is James' age:
Rob's age can be represented by x + 7, since he is 7 years older than James
Kate's age can be represented by x - 2, since she is 2 years younger than James
Add these together in the equation and set it equal to 116:
(x + 7) + (x - 2) + (x) = 116
Add like terms and solve for x:
(x + 7) + (x - 2) + (x) = 116
3x + 5 = 116
3x = 111
x = 37
So, James is 37.
Find Rob's age by adding 7 to this:
37 + 7
= 44
Find Kate's age by subtracting 2:
37 - 2
= 35
So, James is 37, Rob is 44, and Kate is 35
Answer:
Rob = 44
Kate = 35
James = 37
Step-by-step explanation:
Rob = 44 which is 7 years older than James
Kate = 35 which is 2 years younger than James
James = 37
Emily wants to buy new boots that cost $68. The sales tax rate in her city is 512% . What is the total cost for the boots?
Answer:
$71.74
Step-by-step explanation:
<3
The total cost for the boots after the sales tax of 5.12% will be $71.48.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
Emily wants to buy new boots that cost $68. The sales tax rate in her city is 5.12%.
Let x be the total cost for the boots. Then the total cost for the boots will be given as,
x = (1 + 5.12%) × $68
x = (1 + 0.0512) × $68
x = 1.0512 × $68
x = $71.48
The total cost for the boots after the sales tax of 5.12% will be $71.48.

13. 6
Step-by-step explanation:
Answer: 12. x =7 13. x =6
Step-by-step explanation:
Both angles in the triangle has to equal to each other because they are both equivalent.
Set both expressions equal to each other and solve for x.
12. 5x = 35 Divide both sides by 5
x = 7
13. 3x = 5x - 12 Subtract 5x from both sides
-5x -5x
-2x = -12 Divide both sides by -2
x = 6

The parent cubic function f(x) = x^3 is translated to the form g(x) = (x - 4)^3 - 2.
This means the points are shifted right 4 and then down 2.
The point (0,0) on the graph of f(x) corresponds to what point on the graph of g(x)?
Answer choices:
A. (4, -2)
B. (-4, 2)
C. (-4, -2)
D. (-2, -4)
Answer: Option A. (4, -2)
Step-by-step explanation:
Here we have the transformation such that the points are shifted right 4 and then down 2.
We originially have the point (0, 0)
This means that when x = 0, we have f(0) = 0
such that:
f(0) = 0^3 = 0.
Now we have the function:
g(x) = (x - 4)^3 - 2
The equivalent point to the point (0, 0) is such that the input of the function g(x) (the input is (x - 4)) is equal to the input on the original point (x = 0)
The new input is equal to zero when x = 4.
Such that:
g(4) = (4 - 4)^3 - 2 = (0)^3 - 2 = -2
Then we have the point x = 4, y = -2, or (4, -2)
Then the correct option is A.

Answer:
well, x = 5
Step-by-step explanation:
here,
EB Is parallel to DC , so
Angle AEB = Angle ADE
( because they are corresponding angle pair )
Angle ABE = Angle ACD
( because they are corresponding angle pair )
triangle ADC Is similar to triangle AEB
(By AA similarity criteria )
hence AE / ED = AB / BC ( by CPCT )
so 24/10 = 12/x
