Answer:
A
Step-by-step explanation:
To answer this, we need to see what happens to the curves on the given interval
For f(x), we have that there is a decrease as we are moving from a higher positive value of y to a lower positive value of y over the specified interval
For g(x), we can see that we are moving from a lower positive y value to a higher positive y value
What this mean is that the first option is correct
Answer: #7 is A and #8 is D
Step-by-step explanation:
Answer:
Anthony is incorrect
According to the order of operations(PEMDAS), you must first multiply 10 × 3
which equals 30, then you add 2, which equals 32, finally you subtract 2, which brings you back to 30
10 × 3 = 30
2 + 30 - 2 = 30
A vertical line i believe since x is constant
Answer:
P(x < 5) = 0.70
Step-by-step explanation:
Note: The area under a probability "curve" must be = to 1.
Finding the sub-area representing x < 5 immediately yields the desired probability.
Draw a dashed, vertical line through x = 5. The resulting area, on the left, is a trapezoid. The area of a trapezoid is equal to:
(average length)·(width, which here is:
2 + 5
----------- · 0.02 = (7/2)(0.2) = 0.70
2
Thus, P(x < 5) = 0.70
