Multiply points per visit x number of visits, using x for the number of visits:
5.5x
Add that to the points she already has:
5.5x + 60
This needs to equal a total of 104 points:
5.5x + 60 = 104
Now solve for x
5.5x + 60 = 104
Subtract 60 from both sides
5.5x = 44
Divide both sides by 5.5
X = 8
She needs 8 more visits
Hi, my fellow late night studier!
So basically I’m pretending like most of the word problem isn’t there, because word problems tend to want to confuse you with extra information.
I’m just looking at the numbers here.
Let’s take 5.16 and 7 because that’s what we’re working with and we need answers.
Do the math... 5.16+7=12.16
There we have it. The school class traveled a total of 12.16 kilometers on the trip.
I’m so happy to help you and if you have more questions, post them in chat!
Have a great night.

Answer:
Step-by-step explanation:
The alternative hypothesis is the opposite of the null hypothesis
The hypothesis to be tested would be that "there is no difference between the mean number of unpopped kernels from the freezer method and the counter method.
For the null hypothesis,
H0 : μf ≤ μc H0 : μf - μc ≤ 0
The alternative hypothesis is
H1 : μf > μc H1 : μf - μc > 0
Where
f represents the freezer method
c represents the counter method
From the alternative hypothesis, adding μc to both sides of the inequality, it becomes
μf > μc
Therefore, the correct option is
b. μ(freezer) > μ(counter)
