Answer:
The answer to your question is below
Step-by-step explanation:
2 3
Vertex (-4, -9) (-0.5, -3)
Max/min value Min of -9 Min of -3
Axis of symmetry x = -4 -0.5
Zeros -1 and -7 -3 and 2
Direction up up
y-intercept 6 -3
4 5 6
Vertex (-1, -2) (0, 0) (2, 1)
Max/min value Max = -2 Min = 0 Min = 1
Axis of symmetry x = -1 x = 0 x = 2
Zeros None 0 None
Direction down up up
y-intercept -4 0 3
Both are D
First one:
f(g(x)) =f(x^2+3) then you x^2+3 is the x you are going to introduce in the function f
f(x^2+3)= sqrroot(x^2+3-3)= sqrroot (x^2) =x
Second:
you need to leave x alone
y = 3x^2 +1
y-1 = 3x^2
(y-1)/3 = x^2
sqrroot ((y-1)/3) = x
sqrroot ((x-1)/3) = h^-1(x)
Answer:
$21
Step-by-step explanation:
She bought the book for $15.
15 x 40% = 6
Since she rised the price just add 6 to 15
Hope it was helpful ^^ <3
Good Luck
Answer:
b) the mean will be off center in the boxplot and above the median
Step-by-step explanation:
First, we must inform that the median is not affected by outlier. Thus, there is possibility that a (some) student(s) score very high than others. This account for the reason why the mean value is higher than the median.
Since the mean is higher than the median, the score is skewed to the left! That is, majority of the students score low. Hence, we can say that the score is not exactly normal distributed.
NB:
Statistically the mean value given by the teacher is not significantly different from what the students obtained from the sample taken. This implies that, the sample is unbiased of the population mean as given by the teacher.
