Answer:
Mean : 95
Median : 85
Mode : 90
Part B : Impossible
Step-by-step explanation:
We can make an equation to find the mean using the first 5 history test scores.
So a 95 would be needed to have a mean of 85.
Next, the median.
First, we sort the first 5 history scores from least to greatest.
We get 75, 75, 80, 90, 95.
Since, 80 is the middle value, it will be used in the calculation of the median.
We can make an equation with this.
So a score a 85 would be needed to have a median of 82.5
Thirdly, the mode.
Since 90 is already in the set once, we can just have Maliah score another 90 to make 90 the mode (with the exception of 75 of course).
Finally, Part B.
We can use the equation we had for the first mean calculation but change 85 to 90.
So Maliah would need a score of 125 to make her mean score 90, but since the range is only from 0-100, it is impossible.

Answer:
I'm just getting points
Step-by-step explanation:
just points
Answer:
when P(x,y) is reflected in y=x line then
P(x,y) = P(y,x)
A(2, -1)= A(-1, 2)
B(-2, -1) = B(-1, -2)
C(2, 1)= C(1, 2)
D(1,2)= D(2,1)

Answer:
$3355
Step-by-step explanation:
Since the job offers starting salary of $2200 and monthly raise of $105 during his first year of training.
∴ a = 2200 and d = 105
Since the general form of A.P is,
a, a + d, a + 2d, a + 3d, .............
Where, is the last term of A.P or his monthly salary at the end of his training and n is the number of terms in a series.
So, the A.P is:
2200, 2200 + 105, 2200 + 2(105) .........
2200, 2305, 2410 ............
Since there is 12 month in a year therefore, n = 12.
. = 2200 + ( 12 - 1) × 105
= 2200 + 11 × 105
= 2200 + 1155
= 3355
∴ . = 3355
So the monthly salary of Jose at the end of his training is 3355$.
