Answer:
In Grade 8, 17% of students like running.
Step-by-step explanation:
Let's do process of elimination.
For the first choice, we have that In Grade 8, 14 students liked swimming. This is wrong because based on the two-way frequency table, we are dealing with decimals, which can written as percentages. Also, you can't have 0.14 of a person.
Therefore, the first choice is incorrect.
Now for the third choice. The statement is that in Grade 9, 31 percent of students liked volleyball. Okay, so we have a percentage this time. That is a good thing, but we have to know what this percentage means. This answer is incorrect because 31 percent goes with the column of running, not volleyball. It would also be a marginal frequency as well. The 31 percent actually means that 31 percent of all students in both grades liked running. In other words, a total of 31 percent of students in both 8th and 9th grade liked running.
Therefore, the third choice is incorrect.
For the last choice. The statement is 22 students like volleyball. Just like the first choice, we are dealing with percentages, not people.
Therefore, the last choice is incorrect.
Now for the second choice. We are given that in Grade 8, 17 percent of students liked running. We have a percentage, so that is good. This choice is correct because if you were to go to Grade 8 and running. Draw some lines down. You do get to 17 percent. This 17 percent means that 17 percent of students did actually like running. It also means that out of all 8th graders, 17 percent enjoyed running.
Therefore, the second choice is correct.
Hope this helps! I hope you enjoy the rest of your day.

Step-by-step explanation:
The z score is a measure used in statistic to determine the number of standard deviations by which the raw score is above or below the mean. . The z score is given by:
[tex]z=\frac{x-\mu}{\sigma}\\ where\ \mu \ is \ the\ mean, \sigma\ is\ the\ standard\ deviation\ and\ x \ is\ the\ raw\ score[/tex]
(a) Z = -0.12 and Z = 0.12
From the normal distribution table, Area between z equal -0.12 and z equal 0.12 = P(-0.12 < z < 0.12) = P(z < 0.12) - P(z < -0.12) = 0.5478 - 0.4522 = 0.0956 = 9.56%
b) The area that lies between Z = - 0.35 and Z=0
From the normal distribution table, Area between z equal -0.35 and z equal 0 = P(-0.35 < z < 0) = P(z < 0) - P(z < -0.35) = 0.5 - 0.3594 = 0.1406 = 14.06%
c) The area that lies between Z = 0.02 and Z = 0.82
From the normal distribution table, Area between z equal 0.02 and z equal 0.82 = P(0.02 < z < 0.82) = P(z < 0.82) - P(z < 0.02) = 0.7939 - 0.5080 = 0.2859 = 28.59%
HELP ASAP The graph of a function h is shown below. Use the graph to find its average rate of change from x=-7 to x=-5. Simplify your answer as much as possible
Answers
Answer:
The average rate of change from x=-7 to x=-5 is -3
Step-by-step explanation:
In order to calculate average rate of change we would have to make the following calculation:
According to the given data we have the following:
x=-7 so, f(-7) is to be calculated in the graph y
x=-5 so, f(-5) is to be calculated in the graph y
Therefore, average rate of change=f(-5)-f(-7)/-5-(-7)
average rate of change=3-9/2
average rate of change=-6/2
average rate of change=-3
The average rate of change from x=-7 to x=-5 is -3
The average rate of change of a function is the unit change of the function.
The average rate of change from x = -7 to x = -5 is -3
The average rate of change is calculated as:
[tex]\mathbf{f'(x) = \frac{f(b) - f(a)}{b - a}}[/tex]
The interval is given as: x = -7 to x = -5.
This means that:
a = -5 and b = -7
So, we have:
[tex]\mathbf{f'(x) = \frac{f(-7) - f(-5)}{-7 - -5}}[/tex]
This gives
[tex]\mathbf{f'(x) = \frac{f(-7) - f(-5)}{-2}}[/tex]
From the graph
f(-7) = 9 and f(-5) = 3.
So, we have:
[tex]\mathbf{f'(x) = \frac{9 - 3}{-2}}[/tex]
Subtract
[tex]\mathbf{f'(x) = \frac{6}{-2}}[/tex]
Divide
[tex]\mathbf{f'(x) = -3}[/tex]
Hence, the average rate of change from x = -7 to x = -5 is -3

sqrt[(2m^2n)^3]
Step-by-step explanation:
So let's break down the exponent. The top number represents the number of times the term is repeated. The bottom number represents the root to be taken of the final product. With this in mind, let's rewrite this expression.
(2m^2n)^3/2
= [(2m^2n)^3]^1/2

The width of a rectangle is 3 meters more than half of the length. the perimeter is 516 meters. What is the length and the width?
Answers
Answer:
Length = 8 meters
Width = 5 meters
Step-by-step explanation:
2*(3 + (1/4)L + L) = 26 meters
1/4L + L = 26/2 - 3
1/4L + 4/4L = 10
5/4L = 10
L = 10 * 4/5
L = 40/5 = 8 meters
W = 3 + 1/4 L
W = 3 + 1/4 *8
W = 3 + 2
W = 5 meters
Hey there! I'm happy to help!
Let's write this out as a system of equations. We will have W be the width and L be the length.
W=0.5L+3
2L+2W=516
Since we know that W is equal to 0.5L+3, we can swap the W in the second equation with 0.5L+3 so we can solve for L!
2L+2(0.5L+3)=516
We use the distributive property to undo the parentheses.
2L+L+6=516
We combine like terms.
3L+6=516
We subtract 6 from both sides.
3L=510
We divide both sides by 3.
L=170
Now, we know that the width is 3 meters more than half the length. So, we take 1/2 of 170, which is 85, and then we add three, giving us 88.
So, our length is 170 meters and the width is 88 meters.
Have a wonderful day!

xy=12
Hope it helps <3
Explanation:
9/2x = 3y/8
2x • 3y = 8 x 9
2x • 3y = 72
3y = 72/2x = 36/x
y = 36/x • 1/3
y = 36/3x
y = 12/x
Plug y = 12/x in our equation:
9/2x = 3(12/x)/8
9/2x = 36/x/8
2x • 36/x = 9 x 8 (cross multiply)
36x = 72
x = 72/36 = 2
Plug x = 2 in the same to find y
9/2(2) = 3y/8
9/4 = 3y/8
3y x 4 = 72
3y = 72/4 = 18
y = 18/3 = 6

Laura collects old foreign coins. She has 83 coins in total. She has 53 lira and drachma coins. She has 51 lira and peseta coins. How many lira coins does she have?
Answers
Answer: She has 21 lira coins.
Step-by-step explanation:
Given, Laura collects old foreign coins. She has 83 coins in total. She has 53 lira and drachma coins. She has 51 lira and peseta coins.
Let x = the number of lira coins.
y= the number of drachma coins.
z= the number of peseta coins.
Then, as per given, we have
x+y+z=83 (i)
x+y=53 (ii)
x+z=51 (iii)
From (ii) and (iii)
y=53-x
z=51-x
Put these values in (i) , we get
x+(53-x)+(51-x)=83
⇒ x+53-x+51-x=83
⇒ 104-x=83
⇒104-83=x
⇒x= 21
Hence, she has 21 lira coins.

What is the approximate diameter of a sphere with a volume of 34 cm3?
Answers
Answer:
4 centimeters
Step-by-step explanation:
The volume of a sphere can be found using the following formula:
v=4/3*π*r^3
We know the volume is 34 cm^3. Therefore, we can substitute 34 in for v.
34=4/3*π*r^3
We are trying to find r, or the radius. Therefore, we need to get r by itself on one side of the equation.
First, divide both sides by pi.
34/π=4/3*π*r^3 /π
34/π =4/3 * r^3
10.8225361= 4/3 * r^3
Next, divide both sides by 4/3, or multiply by the reciprocal of the fraction.
To find the reciprocal, flip the numerator and denominator of the fraction
4/3 ---flip top number and bottom number --> 3/4
3/4 * 10.8225361= 4/3*r^3 *3/4
3/4* 10.8225361= r^3
8.11690208= r^3
Finally, take the cube root of both sides of the equation.
∛8.11690208=∛r^3
∛8.11690208=r
2.00969477=r
Round to the nearest whole number.
r=2
Now, we must find the diameter. The diameter is twice the radius.
d=2r
The radius is 2 cm.
d= 2 * 2cm
d= 4 cm
The diameter is 4 cm

Donut Haven fries donuts in batches of $20$, but sells them in boxes of $13$. If Donut Haven fries just enough batches of $20$ to pack $44$ full boxes of $13$ donuts, how many donuts will be left over?
Answers
Answer:
The number of doughnuts left over are 8 doughnuts
Step-by-step explanation:
The information given are;
The number of doughnuts fried per batch = 20 doughnuts
The number of doughnuts contained in a pack = 13 doughnuts
The number of doughnut batches just fried = 20 batches
The number of packs filled = 44 packs
The number of packs filled with the fried = 44 packs
The number of doughnuts per pack = 13 doughnuts
The number of doughnuts in the pack = The number of packs filled with the fried × The number of doughnuts per pack
The number of doughnuts in the pack = 44 × 13 = 572 doughnuts
Given that the number of batches of doughnuts fried = X batches and the amount of left over = Y doughnuts, where each batch contains 20 doughnuts, we have;
Number of doughnuts fried = Number of batches of doughnuts fried × Number of doughnuts per batch
Number of doughnuts fried = X × 20 =20×X doughnuts
Therefore we have;
Number of doughnuts fried = The number of doughnuts in the pack + The number of doughnuts left over
Which gives;
20×X = 572 + Y where Y < 20
Checking we have multiples of 20 are 560, 580
Given that 520 is the next multiple of 20 after 572, we have;
The number of doughnuts fried = 580 and the number of left over = 580 - 572 = 8 doughnuts.

Determine an expression for the perimeter of the following shape. I need a step by step solution pleaseeeee:)
Answers
Answer:
The perimeter of the figure is: 8x + 34.
Step-by-step explanation:
The perimeter of a shape is the sum of the length of all its sides. In this case there is one side missing, we need to find its length. To do that we will have to use Pythagora's theorem, because we will create a right triangle as shown in the attached picture. Where a, b and c are the sides of the right triangle. We can determine the lengths of a and c. If we pay close attention to the figure we will realize that a is:
[tex]a = 2x + 5 - 2x = 5[/tex]
While c is:
[tex]c = 2(x + 7) - (x + 5) - (x - 3)\\c = 2x + 14 -x - 5 -x + 3\\c = 2x - 2x + 12\\c = 12[/tex]
We can now apply Pythagora's theorem:
[tex]b^2 = a^2 + c^2\\b^2 = 5^2 + 12^2\\b^2 = 25 + 144\\b = 13[/tex]
With this we can sum all the sides and calculate the perimeter of the shape.
[tex]2x + 5 + x - 3 + 2x + x + 5 + 13 + 2(x + 7)\\2x + x + 2x + x + 2x + 5 - 3 + 5 + 13 + 14\\8x + 34[/tex]
