Answer:
Increasing: 
Decreasing: 
Step-by-step explanation:
So when an equation has and odd degree, it will go in the opposite direction on both ends, so if y went towards infinity as x went towards infinity, then y would go towards negative infinity as x goes towards negative infinity. In this case, by looking at the graph it has an odd degree, due to opposite end behaviors, although on both ends it's increasing because even though it appears that it's going down on the left side, that's only if you start from the right and go towards the left. So it's really increasing from negative infinity to -1, and then it decreases from -1 to 2, until it once again starts increasing from 2 to infinity. This can be represented as (-infinity, -1) U (2, infinity) for increasing and (-1, 2) as decreasing
Answer:
C. The president rejects the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.398, when, in fact, the proportion is 0.398.
Step-by-step explanation:
A type I error occurs if you reject the null hypothesis when it is true.
Now the hypotheses are:
The proportion is 0.398
The proportion is less than 0.398
If in actual fact the proportion is 0.398, then the president must not reject the
.
This is a correct decision.
If in actual fact the proportion is 0.398, and the president rejects the
, then a type I error is committed.
The correct choice is C.

thats the answer right there kid
Answer:
x=23
Step-by-step explanation:
1. Move variable (3x) to the left-hand side and change its sign
Move constant (7) to right-hand side and change its sign
x-7=3x-53
x-3x-7=-53+7
2. Collect like terms [x-3x]
Calculate the sum [-53+7]
x-3x= -53+7
-2x= -46
3. Divide both sides of the equation by -2
-2x/2 =-46/2
4. Solution
x=23
B) 4. I got this by dividing 12 by three and multiplying 4 by 1. Hope this helps you!
