Answer:
Mean = $70.8
Median = $70
Mode = $60
Step-by-step explanation:
From the line plot attached,
Prices of the sunglasses are,
$20, $20, $50, $50, $50, $60, $60, $60, $60, $60, $60, $70, $70, $70, $80, $80, $80, $80, $90, $90, $90, $90, $100, $100, $130
Since mean of the data = Average of the terms
[tex]=\frac{\text{Sum of the terms in the data set}}{\text{Number of terms}}[/tex]
= [tex]\frac{2(20)+3(50)+6(60)+3(70)+4(80)+4(90)+2(100)+130}{(2+3+6+3+4+2+1)}[/tex]
= [tex]\frac{40+150+360+210+320+360+200+130}{25}[/tex]
= [tex]\frac{1770}{25}[/tex]
= $70.8
Median = Middle term of the data set
Since number of terms of the data set are odd (25)
Therefore, median = [tex](\frac{n+1}{2})\text{th term}[/tex] [where n = number of terms in the data set]
= [tex]\frac{25+1}{2}[/tex]
= 13th term
13th term of the data set is $70.
Therefore, Median = $70
Mode = Term repeated the most
In the data set $60 is the term which is repeated the most (6 times).
Therefore, Mode = $60

10. The probability of buying pizza for dinner is 34% and the probability of buying
a new car is 15%. The probability of buying a new car given that you eat pizza for
dinner is 42%. What is the probability of eating pizza for dinner given that they
buy a new car?
Answers
Answer:
The probability of eating pizza given that a new car is bought is 0.952
Step-by-step explanation:
This kind of problem can be solved using Baye’s theorem of conditional probability.
Let A be the event of eating pizza( same as buying pizza)
while B is the event of buying a new car
P(A) = 34% = 0.34
P(B) = 15% = 15/100 = 0.15
P(B|A) = 42% = 0.42
P(B|A) = P(BnA)/P(A)
0.42 = P(BnA)/0.34
P(B n A) = 0.34 * 0.42 = 0.1428
Now, we want to calculate P(A|B)
Mathematically;
P(A|B = P(A n B)/P(B)
Kindly know that P(A n B) = P(B n A) = 0.1428
So P(A|B) = 0.1428/0.15
P(A|B) = 0.952

Answer:
$32.07
Step-by-step explanation:
I am not sure - are we seeing the full information about this problem ?
because the problem description is strangely vague and confusing, as it uses "total cost" two times for not the same thing ...
either total cost means including tax or not including tax. but it cannot mean both ...
I think the most likely understanding of this problem is that the first price is without tax, and now we need to calculate and add the extra 6% tax to get the really total price to be paid.
I will solve this now based on this assumption.
100% = $30.25
1% = 100%/100 = 30.25/100 = $0.3025
6% = 6×1% = 6×0.3025 = $1.815 ≈ $1.82
the total price is then calculated either by
100% + 6%
or by
106% = 100%×1.06 = 30.25×1.06 = $32.065 ≈ $32.07
in both cases we get the same result, of course.

Step-by-step explanation:
3/5 * 15
Rewriting as
3 * 15/5
3 * 3
9
The word "of" tells us we need to multiply.
So 3/5 of 15 means the same thing as (3/5) · (15).
Think of the 15 as 15/1 so when multiplying,
we can cross-cancel the 5 and 15 to 1 and 3.
So we have (3/1) · (3/1) which is 9/1 or just 9.

Set R contains all integers from 10 to 125, inclusive, and Set T contains all integers from 82 to 174, inclusive. How many integers are included in R, but not in T?
Answers
Answer: PLEASE GIVE BRAINLIEST
72 integers
Step-by-step explanation:
Starting From 82-174 every integer is included in T so every integer that is not included in T but included in R would be 82-10 so every integer from 10 to 82.
The number of integers in set R that are not included in set T is 72.
Given:
Set R = {10 to 125}
Set T = {82 to 174}
To find:
number of integers in set R but not in TIntegers from 10 to 81 inclusive in set R are not in set T since set T starts from 82.
Integers in set R but not in set T = {10 to 81}
The number of integers from 10 to 81, inclusive = (81 - 10) + 1
= 71 + 1
= 72
Thus, the number of integers in set R that are not included in set T is 72.

B. 36 ft^2
C. 40.5 ft^2
D. 18 ft^2
Answers
Answer:
The shaded area is 18 ft^2
Step-by-step explanation:
First find the area of the total trapezoid
A = bh
A = 1/2 ( b1+b2) *h
= 1/2 ( 6+12) *6
= 1/2 ( 18)*6
=54
Now find the area of the triangle
A = 1/2 bh
= 1/2 ( 12) * 6
= 36
Subtract the triangle from the trapezoid
54-36
18
The shaded area is 18 ft^2
Answer:
D. 18 sq.ft
Step-by-step explanation:
Lets make it simple and short.
Area of a triangle is 1/2 b h
b = 6
h = 6
Area = 1/2 * 6 * 6
Area = 18 sq.ft

Now factorize the numerator of the fraction.
4x² + 14x - 18 = 2(2x² + 7x - 9)

Below
Step-by-step explanation:
● (a)
Let's determine the difference between the outputs of any two inputs that are one unit apart.
Let m be that difference.
2 and 3 are one unit apart since when you substract 2 from 3 you get 1.
● 3-2 = 1
Let's calculate m.
The output of 2 and 3 are respectively 45 and 53.
● m = 53 - 45
● m= 8
■■■■■■■■■■■■■■■■■■■■■■■■■■
Let's determine the difference between the outputs of any two inputs that are 2 units apart.
Let m' be that difference
3 and 1 are 2 units apart since when you substract 1 from 3 you get 2.
● 3-1 = 2
The outputs of 1 and 3 are respectively 37 and 53.
● m'= 53-37
● m' = 16
■■■■■■■■■■■■■■■■■■■■■■■■■■
Let's determine the difference between the outputs of two inputs that are 3 units apart.
Let m" be that difference
0 and 3 are 3 units apart since when you substract 0 from 3 you get 3.
● 3-0 = 3
Let's calculate m":
The outputs of 0 and 3 are respectively 29 and 53
● m" = 53-29
● m" = 24
■■■■■■■■■■■■■■■■■■■■■■■■■■
● m = 8
● m'= 16
● m" = 24
Notice that all these values are multiples of 8.
● 8 = 8×1
● 16 = 8×2
● 24 = 8×3
Notice that each time the difference m is multiplied by the units that are between the inputs.
This is explained by the fact that the function is a linear one.
When the input interval grows the difference between the outputs grows two.
Answer:
Step-by-step explanation:
find the equation of the linear function in the form of y=mx+b
m=y2-y1/x2-x1 =-3+11/-4+5=8
y=8x+29 ( when x=0, y=b=29)
out put : -3 and -11 -3-(-11)=8 which is 1 unit
out put : 21 and 5 21-5=16 which is 2 unit (2*8)
output :53 and 29 53-29=24 which is 3 units (3*8)
ratio of change = f(b)-(f(a)/b-a
at point -3 and -11 : f(-3)-f(-11)/-4+5=-3+11/1=8
at point 21 and 5 : 21-5/-1+3=16/2=8
the graph always increasing and always equal 8

Each serving of a pancake recipe calls for 1/4 cup of flour. How many servings can be made with 2 cups of flour?
Answers
Answer:
The correct answer is 8 servings of pancakes.
Step-by-step explanation:
If each serving of pancakes calls for 1/4 cup of flour, to find how many servings can be made with 2 cups of flour, we should divide 2 cups by 1/4 cup.
To do this, we can first convert 1/4 to a decimal by dividing the numerator by the denominator.
1/4 = 0.25
Next, we can go ahead with the division.
2 / 0.25 = 8
Therefore, 8 servings of pancakes can be made with 2 cups of flour.
Hope this helps!
