In order for the data in the table to represent a linear function with a rate of change of +5, what must be the value of a?
a = 3
a = 8
a = 18
a = 33
Answer: C: A=18
Step-by-step explanation: If your are adding 5 every time the x value goes up by one, then you would add 5 to13, henceforth getting 18.
The value of a that completes the table is 18
Rate of change of a functionThe rate of change of a function is expressed in term of the slope.
In order to determine the value of a, we will use the expression below;
Slope = a - 13/4-3 = 23-13/5-3
a-13 = 10/2
a - 13 = 5
Add 13 to both sides
a =5 + 13
a = 18
Hence the value of a that completes the table is 18

A total of 40 parents volunteered to bring a cake for the Holiday fair.Of the 40 volunteers that brought cake,10 of them brought two cakes. Out of all the cakes at the holiday Fair , 30% were chocolate. How many cakes were chocolate?
Answer:
15!
Step-by-step explanation:
so 40 people volentered to bring cakes, but 10 brought 2. So (30*1)+(10*2)=50 cakes. So, 30 percent of 50 cakes would be 15. To double check, times 50 by 100 and then 30 percent would become 30 (making super sure the actual answer is 15)

Mean = 69Median = 69Mode = {68, 70}===============================================
Explanations:
To get the mean, you add up all of the values and then you divide by N, where N is the number of values in the list. In this case, you'll divide by N = 8.
Adding up all the values gets you 70+68+70+72+68+66+65+73 = 552. Dividing that over 8 then leads to the arithmetic mean of 552/8 = 69
-------
To find the median, you'll first sort the values from smallest to largest. You should have this set {65, 66, 68, 68, 70, 70, 72, 73} after sorting. Next, cross off the smallest and largest values to end up with this smaller set {66, 68, 68, 70, 70, 72}. We do this so we can locate the middle-most item.
Repeat the process of crossing off the smallest and largest items to get {68, 68, 70, 70}. Do so one more time and we get {68,70}.
The midpoint of those two values is (68+70)/2 = 138/2 = 69. The median is 69. The mean and median may not always be the same value.
--------
The mode is the most frequent value. In this case, we have 68 and 70 show up exactly twice for each unique value. This is the most compared to the other unique values that only show up exactly once.
It is possible to have more than one mode, as long those values are more frequent than the rest. We denote the mode as a set, so the mode is {68, 70}
Can angles that measure 60, 60 and 60 degrees form exactly one triangle, more than one triangle or no triangle? Why?
Answer:
Yes, a 60,60,60 angle triangle equals 180
Step-by-step explanation:
Every triangle has to equal 180 degrees or it's not a triangle at all. This forms 1 triangle.

Which of the following is the solution to the equation 64^(z+4) = 1024
A triangle has sides with lengths of 10 millimeters, 17 millimeters, and 18 millimeters. Is it a right triangle?
Answer:
no, it is not
if it were a right triangle, 10² + 17² = 18²
but this is not the case
Step-by-step explanation:
we would use Pythagoras theorem to determine if it is a right angle
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
10² + 17² =
100 + 289 = 389
square root of 389 is 19.72 and not 18. thus, it is not a right triangle
A company surveyed its employees regarding the number of miles
commuted each day. The data set below shows the results
9, 15, 26, 32, 65, 5, 10, 19, 26, 32, 8, 15, 25
30, 40, 7, 12, 21, 27, 35, 60, 29, 23, 14,8
Using a box plot, determine the outlier value of the data set above.
A. 65
OB. 23
C. 60
D. The data set does not contain an outlier.
E. 5
Answer: According to Study Island the answer is 65
Step-by-step explanation:
In order to determine the outlier value, create a box plot.
To create a box plot, order the data.
5, 7, 8, 8, 9, 10, 12, 14, 15, 15, 19, 21, 23, 25, 26, 26, 27, 29, 30, 32, 32, 35, 40, 60, 65
Find the median, the first quartile (Q1), the third quartile (Q3), and the interquartile range (IQR).
Median = 23
Q1 =
10 + 12
2
= 11
Q3 =
30 + 32
2
= 31
IQR = Q3 - Q1 = 31 - 11 = 20
Find the upper and lower fences for the given data.
Lower Fence = Q1 - 1.5 × IQR
= 11 - 1.5 × 20
= -19
Upper Fence = Q3 + 1.5 × IQR
= 31 + 1.5 × 20
= 61

What is the height of a cone that has a volume of 90 mand has a radius of 3.5 m?
Answer:
Step-by-step explanation:
Calculate the volume of a cone by its base and height with the equation volume = 1/3 * base * height. You can calculate the height of a cone from its volume by reversing this equation. Triple the volume amount. For this example, the volume is 100.

Jane has saved 600 dollars in a college fund. She added money to the account over the next year and at the end of the year, the account had 890 dollars.
!! Write an equation to represent the amount she saved over the year. !!
Answer:
S=End amount-Starting amount
Or(with values)
290=890-600
Step-by-step explanation:
So lets get together all our variables.
First, lets create a variable that shows the amount of money saved over the year.
Lets use S, for savings.
Next, lets take our end value, which was 890, and subtract it from our orgninal value.
This will get you the amount of money that Jane earned over the year. This will look like:
890-600
Or
End value=orginal value.
Now S will be equal to the amount of money Jane earned.
So we can write this as:
S=890-600
Or
Amount of money earned=end value-orginal value
Hope this helps!
