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.
I put in the x coordinate for where y was 80 and the y coordinate for where x was 3. Then I subtracted them to get the slope. Hope this helps.
Answer:
EIther 45 or 15
Step-by-step explanation:
Speed is the ratio of distance and time. When we divide f(x) by g(x) we will get the speed of the flock that is 9 miles/hour.
<h3>What is speed?</h3>
Speed can be defined as the rate of change in the position of an object. It is given as,

Given to us
Distance traveled, f(x) = 2x+26
Time, g(x) = x − 1
As we know that the ratio of distance and time is equal to the speed of the object. Since the distance traveled by the flock of birds is given also, the time needed for them to travel the distance is also given.
We need to find f divided by g of 5, which is the speed of the flock,



Hence, when we divide f(x) by g(x) we will get the speed of the flock that is 9 miles/hour.
