Answer:
"30 years or less when, in reality, the average age is more than 30 years"
Step-by-step explanation:
Type I error is produced when conclusion rejects a true null hypothesis.
The null hypothesis is
"The average gamer is more than 30 years old"
(deduced from the wording, not explicitly stated).
Then if the conclusion is "the average gamer is less than or equal to 30 years old" when in reality the average age is more than 30 years, then there is a type I error, since the null hypothesis is rejected.
Answer is D:
"30 years or less when, in reality, the average age is more than 30 years"
Answer:
2.5y=amount spent on drinks
Step-by-step explanation:
If chips are $2 and drinks are $2.50 and we do not know how many he bought of each, we put this into an equation which is
2x+2.5y
x=number of bags of chips while the 2 is two dollars per bag
so, if he bought 2 bags of chips 2(2)= $4 spent.
y= number of drinks and 2.5 is $2.5 per drink, so if he bought 4 drinks:
2.5(4)= $10 spent on drinks.
Answer:

Step-by-step explanation:
I think the correct one is C. 130
STEP 1:
Find percentage. 57 out of 100 is the percentage to multiply by.
57/100= 0.57 (= 57%)
STEP 2:
Multiply percentage by the total gallons ordered (24).
=24 gallons * 0.57
=13.68 gallons
ALTERNATIVE METHOD (use which works best for you)
Set up a proportion. 57 to 100 is x out of 24 gallons.
x= number skim gallons to order
57/100= x/24
cross multiply
(57*24)= (100*x)
1368= 100x
divide both sides by 100
13.68 gallons= x
ANSWER: Since you cannot order a partial gallon of milk, round up to 14 whole gallons
