Answer: I think the answer is B
Step-By-Step Explination:
First you find out what x is by doing 42 multiplying it by 0.1 witch equals 4.2 gallons per mile
Next you figure out what y is by doing 4.2y (witch is 4.2 times y)
Hello!
I believe the answer is C.
I hope it helps!
Answer:
15
Step-by-step explanation:
3x+15=60
3x=45
x=15
Answer:
test statistic is ≈ -0.36
p-value is ≈ 0.64
There is no significant evidence that the average golfer can hit the ball more than 235 yards on average.
Step-by-step explanation:
a hypothesis test where H_0: mu = 235 and H_1:mu > 235
test statistic can be calculated as follows:
z=
where
- sample mean driving distance (233.8 yards)
- M is the average expected distance that the average golfer can hit the ball under null hypothesis. (235 yards)
- s is the standard deviation (46.6 yards)
- N is the sample size (192)
Then test statistic is z=
=-0.3568
p-value is 0.64 >0.05
There is no significant evidence that the average golfer can hit the ball more than 235 yards on average.
So first find out how many can be done in 1 minute.
In an equation it would be 3x=42
Divide by 3
x=14
So 14 pushups can be done in 1 minute (congratulations to this person I can barely do one haha)
So now you multiply what you can do in 1 minute by 5 minutes.
14x5= 70 pushups
