Tony’s Pizzeria customers were asked what kind of pizza topping they prefer. Tony learned that 20 customers selected pepperoni, 12 selected mushrooms, and 8 selected pepperoni and mushrooms. What is the probability that a randomly selected customer selected pepperoni but not mushrooms?
A.1/2
B.2/5
C.3/5
D.3/8
Answers
Answer:
A. 1/2
Step-by-step explanation:
First, find how many customers there were:
20 + 12 + 8
= 40
20 customers selected pepperoni only, so to find the probability that they chose pepperoni but not mushrooms, divide the amount by the total:
20/40
= 1/2
So, the probability is 1/2

Answer:
x = 2/3
Step-by-step explanation:
9x + 4 = 6x + 6
Subtract 4 from both sides
9x + 4 - 4 = 6x + 6 - 4
9x = 6x + 2
Subtract 6x from both sides
9x - 6x = 2
3x = 2
Divide both sides by 2

Jacki evaluated the expression below. 2 cubed (3 minus 1) + 4 (8 minus 12) = 2 cubed (2) + 4 (4) = 8 (2) + 16 = 16 + 16 = 32. What was Jacki's error?
Answers
Answer:His error lies in the subtraction of 12 from 8 , he wrote 4 instead of -4 , as 8-12 gives -4 instead of 4.
Step-by-step explanation:
Step 1
Rewriting this to a mathematical expression 2 cubed (3 minus 1) + 4 (8 minus 12) and solving correctly gives
2³(3-1)+ 4(8-12)
=8(2) + 4(-4)
= 16 +(-16)
16-16=0
Step 2-----Jacki's evaluation
2³(3-1)+ 4(8-12)
= 2³(2) +4(4)
= 8(2) +16= 16+ 16 =32
His error lies in the subtraction of 12 from 8 , he wrote 4 instead of -4 , as 8-12 gives -4 instead of 4.

Let:
([tex]x_1 , y_1[/tex]) = (1 , 2)
([tex]x_2 , y_2[/tex]) = (7 , 7)
Plug in the corresponding numbers to the corresponding variables:
slope (m) = [tex]\frac{7 - 2}{7 - 1} = \frac{5}{6}[/tex]
slope (m) = [tex]\frac{5}{6}[/tex]
~
[tex] \LARGE{ \underline{ \purple{ \bf{Required \: answer:}}}}[/tex]
We can find the slope (m) by using the formula:
[tex] \rm{m = \dfrac{y2 - y1}{x2 - x1} }[/tex]The points given to us:
(x1 , y1) = (1 , 2)(x2 , y2) = (7 , 7)Plugging the given values of x1, y1, x2 and y2 to find the slope:
[tex] \rm{m = \dfrac{7 - 2}{7 - 1} }[/tex]
This is equals to,
[tex] \rm{m = \dfrac{5}{6} }[/tex]

Nicole is making tuna salad for her office colleagues. It takes 2/5 of a pound of canned tuna to make 5 portions of salad. She uses 1 1/5 pounds of canned tuna for every 2 onions used. If Nicole uses a total of 4 onions, then how many portions of salad does she make?
Answers
Answer:
30 portions of salad
Step-by-step explanation:
Given that :
2/5 pounds of canned tuna = 5 portions of salad
For every 2 onions used, 1 1/5 pounds of canned tuna is used ;
Number of onions used = 4
If 4 onions were used, number of canned tuna used is ;
4 /2 * 1 1/5
= 2 * 1 1/5
= 2 * 6/5
= 12 / 5 = 2 2/5 pounds of canned tuna
Number of Portions of salad made :
2/5 pounds = 5 portions of salad
12/5 pounds = x
2/5 * x = 12/5 * 5
2/5x = 60 /5
2/5 x = 12
x = 12 ÷ 2/5
x = 12 * 5 /2
x = 60/2
x = 30 portions of salad

The and age of each child in a random sample of children was recorded The value of the correlation coefficient between height and the children in the sample was 0.8 . Based on the line created from the data to the height of a child based on age which of the following is a correct statement ?
Answers
Options :
A.) On average, the height of a child is 80% of the age of the child.
B.) The least-squares regression line of height versus age will have a slope of 0.8.
C.) The proportion of the variation in height that is explained by a regression on age is 0.64.
D.) The least-squares regression line will correctly predict height based on age 80% of the time.
E.) The least-squares regression line will correctly predict height based on age 64% of the time.
Answer:
C.) The proportion of the variation in height that is explained by a regression on age is 0.64.
Step-by-step explanation: from the scenario stated above, The correlation Coefficient R = 0.8, which shows the strength of relationship between age and height of children. From the value of correlation Coefficient Given, we can obtain the Coefficient of determination (R²) which gives the percentage of Variation which can be explained by the regression model.
Hence the Coefficient of determination (R²) = 0.8² = 0.64. Hence, the proportion of variation in height of children which can he due to age is 0.64 while 0.36 can be based on other factors.
Based on the line created from the data to the height of a child based on age the correct statement is given by: Option C.) The proportion of the variation in height that is explained by a regression on age is 0.64.
How can we get to know the variability of one variable to other from correlation coefficient?For that, we can use the coefficient of determination.
The coefficient of determination is square of correlation coefficient and thus, ranges from 0 to 1.
The coefficient of determination tells for unit variation in one variable will lead to how much variation in other variable and vice versa.
Let we take:
X = age of children of the sample considered
Y = height of children of the sample considered
Then, as it is given that:
[tex]r(X, Y) = 0.8[/tex]
Thus, the coefficient of determination is: [tex]r^2 = 0.8^2 = 0.64[/tex]
Thus, we get that 0.64 of the variation in the height is explained by the age of the children.
Thus, the true statement is:
Option C.) The proportion of the variation in height that is explained by a regression on age is 0.64.

In an AP. 19th term is 52 and 38th term is 128. Find the sum of the first 56 terms.
Answers
19th term of an AP = 52
38th term = 128
Find:the sum of the first 56 terms
Solution:We know that,
nth term of an AP – a(n) = a + (n - 1)d
Hence,
→ a + (19 - 1)d = 52
→ a + 18d = 52 -- equation (1)
Similarly,
→ a + (38 - 1)d = 128
→ a + 37d = 128 -- equation (2)
Subtract equation (1) from (2).
→ a + 37d - (a + 18d) = 128 - 52
→ a + 37d - a - 18d = 76
→ 19d = 76
→ d = 76/19
→ d = 4
Substitute the value of d in equation (1).
→ a + 18 * 4 = 52
→ a = 52 - 72
→ a = - 20
We know,
Sum of first n terms of an AP – S(n) = n/2 * [ 2a + (n - 1)d ]
Hence,
→ S(56) = 56/2 * [ 2 (- 20) + (56 - 1) * (4) ]
→ S(56) = 28 * [ - 40 + 55 * 4 ]
→ S(56) = 28 * [ - 40 + 220 ]
→ S(56) = 28 * (180)
→ S(56) = 5040
Hence, the sum of first 56 terms of the given AP is 5040.
I hope it will help you.
Regards.
The sum of the first 56 terms of the given AP is 5040.
What is an arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmetic progression. A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.
Given that in an AP. 19th term is 52 and 38th term is 128.
nth term of an AP – a(n) = a + (n - 1)d
a + (19 - 1)d = 52
a + 18d = 52 -- equation (1)
Similarly,
a + (38 - 1)d = 128
a + 37d = 128 -- equation (2)
Subtract equation (1) from (2).
a + 37d - (a + 18d) = 128 - 52
a + 37d - a - 18d = 76
19d = 76
d = 76/19
d = 4
Substitute the value of d in equation (1).
a + 18 * 4 = 52
a = 52 - 72
a = - 20
Sum of first n terms of an AP – S(n) = n/2 * [ 2a + (n - 1)d ]
S(56) = 56/2 * [ 2 (- 20) + (56 - 1) * (4) ]
S(56) = 28 * [ - 40 + 55 * 4 ]
S(56) = 28 * [ - 40 + 220 ]
S(56) = 28 * (180)
\S(56) = 5040
Hence, the sum of the first 56 terms of the given AP is 5040.
