The statement best describes the mean of this set is the sum of the prices divided by 7.
What is Mean?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
Mean of a set of data can be found by adding all the values of the data set and by dividing by the total number of values in the data set.
Given data set is the prices of T-shirts at a clothing store.
{8, 10, 10, 12, 15, 15, 18}
Mean of the data set = Sum of the prices/ Total number of values
Sum of the prices = 8 + 10 + 10 + 12 + 15 + 15 + 18 = 88
Total number of value in the set = 7
Mean = 88 / 7 = 12.574
Hence the mean can be found by adding up all the prices divided by 7.

(I put 1/4 but it said it was wrong:/) pls help h
Answers
Answer:
Pizza eaten together: 5/6,
Pizza left over: 1/6
Step-by-step explanation:
~ If Ellen ate 2/4th of the pizza and John ate 1/3 of the pizza, provided that the pizza counts as a whole ( 1 )... ~
1. Let us simplify 2/4th to be ⇒ 1/2, through simple algebra
2. To see how much they ate together we would neglect that the pizza counts as a whole but simply add 1/2 by 1/3rd.
3. Through simple algebra: 1/2 + 1/3 = 3/6 + 2/6 = Pizza eaten together: 5/6
4. Now to find out how much pizza was left over, we would need the fact that a pizza ⇒ 1 whole. It would be that 1 - 1/2 - 1/3 ⇒ Pizza left over, through the Partition Postulate. In fact, the pizza left over would simply be 1 whole - the pizza eaten together ( 5/6 ).
5. Through algebra: 1 - 1/2 - 1/3 = 1 - 5/6 = Pizza left over: 1/6
Answer:
How much did they eat all together? 5/6
How much was left over? 1/6

Step-by-step explanation:
How much did they eat all together?

Does the frequency distribution appear to be a normal distribution? The frequency distribution could reasonably be a normal distribution because the frequencies start low, increase, and then decrease, and are roughly symmetric.
Answers
Answer:
Step-by-step explanation:
Hello!
To arrange the data in a frequency table you have to determine the class intervals first. Normally you'd choose the number of intervals you want to work with and then calculate the class width by dividing the number ob observations, n, by the number of intervals, then, starting from the minimum value as the lower limit of the first interval, you add the width to calculate the upper interval. For the next interval, you use the upper limit from the previous one and add the width to determine the upper limit, and so on until you reach the desired number of intervals.
For this exercise the width was determined 0.50 and the lower limit for the first interval 0.00:
1st interval: 0.00+0.50= 0.50: [0.00; 0.50)
Then:
[0.50; 1.00)
[1.00; 1.50)
[1.50; 2.00)
[2.00; 2.50)
[2.50; 3.00)
Next is to arrange the data from least to greatest and count how many fit in each interval:
0 , 0,09, 0,18, 0,24, 0,31, 0,36, 0,39, 0,39, 0,41, 0,45, 0,55, 0,55, 0,63, 0,64, 0,64, 0,64, 0,64, 0,64, 0,69, 0,69, 0,71, 0,71, 0,73, 0,74, 0,78 ,0,79, 0,79, 0,79 ,0,83, 0,83, 0,83 , 0,85, 0,89, 0,91, 0,92, 0,92, 0,93,0,94, 0,98, 0,98 ,0,99, 0,99, 0,99,0,99, 1,01, 1,01, 1,01, 1,01, 1,22, 1,23,1,24, 1,24 , 1,24, 1,25 ,1,,25 , ,1,25,1,26 , 1,26, 1,27, 1,28 ,1,31 , 1,33 , 1,34 , 1,34 ,, 1,35, 1,35 , 1,38 , 1,39 , 1,41 , 1,42 , 1,42 , 1,43 , 1,44 , 1,44 , 1,45 , 1,46 , 1,49 , 1,49 , 1,56 , 1,56 , 1,62 , 1,63 , 1,65 , 1,65 , 1,75 , 1,77 , 1,78 , 1,78 , 1,82 , 1,85 , 1,96 , 1,98 , 2,19 , 2,21 , 2,23 , 2,24 , 2,47 , 2,49 , 2,95 , 2,97

Answers
Answer:
1024 pi
Step-by-step explanation:
The area formula is ...
A = πr^2
So, the radius is ...
r = √(A/π)
For the given area, the radius of the cylinder is ...
r = √(64π/π) = 8 . . . . cm
The height is said to be twice this value, so is 16 cm.
__
The volume of the cylinder is found from ...
V = Bh
where B is the base area and h is the height. Our cylinder has a volume of ...
V = (64π cm^2)(16 cm) = 1024π cm^3

Answers
Answer:
[tex]x=\frac{3}{2}\\ y=\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]y=-x+2\\y=3x-4[/tex]
Let's solve one of them for x.
[tex]y=3x-4[/tex]
Add 4
[tex]y+4=3x[/tex]
Divide by 3.
[tex]x=\frac{y+4}{3}[/tex]
Now, plug the value of y in the formula, or you can plug the value of x in the other equation. I'll take this one.
[tex]x=\frac{y+4}{3}[/tex]
[tex]x=\frac{(-x+2)+4}{3}[/tex]
[tex]x=\frac{-x+2+4}{3}[/tex]
[tex]x=\frac{-x+6}{3}[/tex]
Multiply by 3 to get rid of the denominator.
[tex]3x=-x+6[/tex]
add x
[tex]3x+x=6[/tex]
Combine like terms;
[tex]4x=6[/tex]
Divide by 4.
[tex]x=\frac{6}{4}[/tex]
Simplify.
[tex]x=\frac{3}{2}[/tex]
Now that you found the value of x, replace it in any of the equations to find y.
[tex]y=-x+2\\y=-(\frac{3}{2})+2\\ y=-\frac{3}{2}+2[/tex]
[tex]y=\frac{-3+2*2}{2} \\y=\frac{-3+4}{2} \\y=\frac{1}{2}[/tex]
Proof:
[tex]y=3x-4\\\frac{1}{2}=3(\frac{3}{2})-4\\\frac{1}{2}=(\frac{9}{2})-4[/tex]
[tex]\frac{1}{2}=\frac{9-4*2}{2}[/tex]
[tex]\frac{1}{2}=\frac{9-8}{2}[/tex]
[tex]\frac{1}{2}=\frac{1}{2}[/tex]

Jason and Melinda are both driving from Fort Worth, Texas, to Van Horn, Texas. Jason leaves at 8:30 and averages 60 mph (miles per hour) on the way. Melinda leaves at 9:00 and averages 70 mph on the way. The situation is modeled by this system, where x is the number of hours after melinda leaves and y is the distance each will travel : y=60 x+30 y=70 How long after Melinda leaves will she pass Jason, and how far will they each have traveled?
Answers
Answer:
Melinda will pass Jackson 3 hours after she leaves.
They will have traveled 210 miles.
Step-by-step explanation:
We need to build linear functions for their positions starting at 9 am.
We choose 9 am because it is the time of the last person leaving.
Melinda:
Leaves at 9 (from position 0).
Averages 70 mph.
So
[tex]y_{M}(t) = 70t[/tex]
Jason:
Leaves at 8:30, 60 mph.
At 9, when Melinda leaves, 30 minutes(half an hour will have passed). He will be at the position 0.5*60 = 30. So
[tex]y_{J}(t) = 30 + 60t[/tex]
How long after Melinda leaves will she pass Jason
This is t for which:
[tex]y_{M}(t) = y_{J}(t)[/tex]
[tex]70t = 30 + 60t[/tex]
[tex]10t = 30[/tex]
[tex]t = \frac{30}{10}[/tex]
[tex]t = 3[/tex]
Melinda will pass Jackson 3 hours after she leaves.
How far will they each have traveled?
Either [tex]y_{M}(3)[/tex] or [tex]y_{J}(3)[/tex]. They are the same value.
[tex]y_{M}(3) = 70*3 = 210[/tex]
They will have traveled 210 miles.

In a math class of 32 students, 18 boys and 14 are girls. On a unit test, 5 boys and 7 girls made an A grade. A student is chosen at random from the class. What is the probability of choosing a girl or an A student?
Answers
Answer:
14+7=21
The probability is 21/32 or 65,625%
Step-by-step explanation:
You just add the number of girl students (including the ones that got an A) with the number of boys that got an A
Then you divide that number by the total of students (32)
The probability of choosing a girl or an A grade student is 19/32.
What is probability ?Probability is the chance or possibility to occur any selected event.
If the number of possible outcomes of an event is divided by the total number of outcomea of the event then it is called probability of that particular event.
What is the required probability ?In a maths class,
The total number of students = 32
No. of boys = 18 & no. of girls = 14
On an unit test, 5 boys made an A grade whereas 7 girls made an A grade.
The probability of choosing a girl = 14/32 = P(A) (say)
And, The probability of choosing an A grade student = 12/32 = P(B) (say)
Hence, the probability of choosing an A grade student who is a girl = P(A∩B) = 7/32
∴ The probability of choosing a girl or an A grade student =
P(A∪B) = P(A)+P(B)-P(A∩B)
= 14/32+ 12/32-7/32
= 26/32-7/32
= 19/32
Hence, The required probability is 19/32.

The cost, in dollars, to produce 1 watt of solar energy is a function of the number of years

2. What is f(4)? What about f (3.5)? What do these values represent in this context?
3. When f(t) = 45, what is t? What does that value of t represent in this context?
4. By what factor did the cost of solar cells change each year? (If you get stuck consider
creating a table.)
Answers
Answer:
In the figure attached, the graph of the function is shown.
1. f(9) ≈ 6 means that at t = 9 (year 1977 + 9 = 1986) the cost to produce 1 watt of solar energy was $6
2. f(4) ≈ 25, which means at year 1981 (=1977 + 4) the cost was $25 per watt
f(3.5) ≈ 28, which means at half of year 1980 (=1977 + 3.5) the cost was $28 per watt
3. When f(t) = 45, t is equal to 2, which means that the year wass 1979 (= 1977 + 2)
4. From the graph we can compute the following table:
x | y
0 | 80
1 | 60
The general exponential decay formula is:
f(x) = a*b^x
where a is the initial value and b si the decay factor. Replacing with data from the table:
f(0) = a*b^0
80 = a
f(1) = a*b^1
60/80 = b
0.75 = b
