Name Games Strikes Elena 10 7 Jenna 7 8 Freya 3 6 Ginny 6 12 Carol 13 15 Katie 9 18 The graph shows the relationship between each player’s games and strikes. Determine which team members have the same ratio of games to strikes, and select their corresponding points on the graph.
Answer:
Step-by-step explanation:
It's asking for those who have the same amount of strikes to the amount of games. For example Jenna gas played 7 games, and Elena has gotten 7 strikes. Their asking how many members have gotten the same amount of strikes to the amount of games they've played.
This should be a big help.

If a figure is reflected over the x-axis and then reflected over the y-axis, what one transformation would accomplish the same end resulting figure?
Answer:
rotation
by rotating the figure clockwise 180 degrees you would get the same thing as reflected it over the x and then the y axis
In most cases; when an object is transformed, the orientation and layout of the object changes. The one transformation that will accomplish this is 180 degrees rotation.
Let the point on the figure be (x,y)
When reflected over the x-axis, the transformation rule is:
[tex](x,y) \to (x,-y)[/tex]
When reflected over the y-axis, the transformation rule is:
[tex](x,y) \to (-x,y)[/tex]
This means that:
[tex](x,-y) \to (-x,-y)[/tex]
So, the reflection is:
[tex](x,y) \to (x,-y) \to (-x,-y)[/tex]
The single transformation that can achieve this is: rotation by 180 degrees.
The rule of transformation is:
[tex](x,y) \to (-x,-y)[/tex]
Hence, one transformation that would accomplish the reflections is: 180 degrees rotation.

Sofia is investing $8,000 in an account paying 5.5% interest compounded quarterly. What will Sofia's account balance be in 7 years?
Sofia's account balance in 7 years will be $11,726.12
Compound InterestFrom the question, we are to determine Sofia's account balance in 7 years
Using the compound interest formula,
[tex]A = P(1+ \frac{r}{n} )^{nt}[/tex]
Where A is the amount
P is the principal
r is the rate
n is the number of times compounded
and t is the time in years
From the given information,
P = $8,000
r = 5.5% = 0.055
n = 4
t = 7
Putting the parameters into the equation, we get
[tex]A = 8000(1+ \frac{0.055}{4} )^{4\times 7}[/tex]
[tex]A = 8000 ( 1+ 0.01375)^{28}[/tex]
[tex]A = 8000 ( 1.01375)^{28}[/tex]
A = $11,726.12
Hence, Sofia's account balance in 7 years will be $11,726.12

Assume the population has a normal distribution. A sample of 25 randomly selected students Has a mean test score of 81.5 With a standard deviation of 10.2. Construct a 90% confidence interval for the mean test score.
Answer:
The 90% confidence interval for the mean test score is between 77.29 and 85.71.
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 2.064
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.064\frac{10.2}{\sqrt{25}} = 4.21[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 81.5 - 4.21 = 77.29
The upper end of the interval is the sample mean added to M. So it is 81.5 + 4.21 = 85.71.
The 90% confidence interval for the mean test score is between 77.29 and 85.71.

find the total surface area of this cone, leaving your answer in terms of pi
Answer:
I need numbers to do a step by step
but the formula for the surface area of a cone.
Firstly, you work out the circle, pi x radius squared.
then you work out the cone
You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (πrl).
So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:
SA = πr2 + πrl

Answer:
Surface area = 92 ft²
Step-by-step explanation:
Formula to find the surface area of a rectangular prism is,
Surface area = 2(lb + bh + hl)
Here, l = length of the prism
b = width of the prism
h = height of the prism
By substituting the measures of the sides given in the picture,
Surface area = 2(2×3 + 3×8 + 8×2)
= 2(6 + 24 + 16)
= 2(46)
= 92 square feet
Therefore, surface area of the given rectangular prism is 92 ft².

A plant farm sells bundles of rose bushes. Each bundle contains 150 rose bushes and has the same ratio of hybrid tea roses, climbing roses, tree roses, and miniature roses. A landscaper purchased i bundle of rose bushes and found the bundle contained 9 climbing roses. He buys a second bundle of rose bushes for a large planting job he needs to complete, bringing his total to 300 rose bushes. How many of the roses being planted will NOT be climbing roses?
A. 282
B. 318
C.18
D. Not here
Answer:
since all bundles contain the same amount of each type of rose, and one bundle has 9 climbing roses. two bundles will have 18 climbing roses. the question wants to know how many roses out of the two bundles won't be climbing roses. so you need to do: 300 - 18 = 282

An angle measures 80° less than the measure of its complementary angle. What is the measure of each angle
Answer:
let the angle be x and the complementary angle be y
so, x+y=90 and given,
x=y-80
solving both the equations,
x = 5
y = 85
so the angles are 5 and 85

Answer:
m∠G = m∠H = 50
m∠I = 80
Step-by-step explanation:
m∠H = m∠G {Isosceles triangle property}
5x - 5 = 3x + 17 {Subtract 3x from both sides}
5x - 3x - 5 = 17 {Combine like terms}
2x - 5 = 17 {Add 5 to both sides}
2x = 17 + 5
2x = 22
x = 22/2
x = 11
m∠H = 5x - 5
= 5*11 - 5
= 55 - 5
m∠H = 50
m∠G = m∠H = 50
m∠G + m∠H + m∠I = 180 {Angle sum property}
50 + 50 + m∠I = 180
100 + m∠I = 180
m∠I = 180 - 100
m∠I = 80
Answer:
m∠G = m∠H = 50
m∠I = 80

A total of 2 feet of snow falls over three days. On the first day, 1/6 of the total snow falls. On the second day, 7/12 of the total snow falls.
On third day 1/2 of the total snow falls.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given that, total of 2 feet of snow falls over three days.
On the first day, 1/6 of the total snow falls. On the second day, 7/12 of the total snow falls.
So, the snow fall on third day will be
= 2(1-1/6-7/12)
= 2((12-2-7)/12)
= 2(3/12)
= 2(1/4)
= 1/2
Therefore, on third day 1/2 of the total snow falls.
