Answer:
B. Correct decision
Step-by-step explanation:
We know that the average math SAT score of students at the school has changed from the 1991 mean of 465. That is μ≠465.
This hypothesis was tested and the null hypothesis, that states that the average math SAT score of students at the school has not changed from the 1991 mean, was rejected.
Then, the conclusion of rejecting the null hypothesis is right, as μ=465 is false.

Answer:
40 sweets
Step-by-step explanation:
Let june have x sweets
may has 3x/4 sweets
April has x/2 sweets
total sweets is 90
Adding all sweets =
x/2+3x/4+x = 90
9x = 360
x = 40
Therefore June has 40 Sweets
To find the answer to this problem, you can use the unit circle to see that pi over 6 radians is equal to 30°
Another way is to use the equation: degrees = radians • (180 over pi)
In this example, plugging in the radians portion of the equation gives us: degrees = (pi over 6) • (180 over pi), which will become degrees = (180pi over 6pi)
Simplify and pi cancels out to give us degrees = 30
Answer: 30°
Let g the inverse function of f.
The most important property of g and f being inverses of each other, is that
g(f(x))=x, also f(g(x))=x
so, what one function 'does' to x, the other 'undoes' it.
Thus, we have:
f(g(x))=x and alos f(g(x))= -g(x)+3, from the rule
thus :
-g(x)+3=x
-g(x)=x-3
g(x)=-x+3
check: f(g(x))=f(-x+3)=-(-x+3)+3=x-3+3=x
Answer: the inverse of f is g, such that g(x)=-x+3
