<span>x + 3y = 5
2x - 3y = 1
------------------add
3x = 6
x = 2
</span>x + 3y = 5
2 + 3y = 5
3y = 3
y = 1
answer x = 2 y = 1
Answer:
d. H0 : pˆ = .6, Ha: pˆ > .6
Step-by-step explanation:
Given that a minister claims that more than 60% of the adult population attends a religious service at least once a month.
Here the subject of interest about a proportion of adult population who attends a religious service at least once a month.
The claim is this proportion is greater than 60% and we want to check whether this claim is true.
Hence hypotheses would be for proportion only and not mean.
Since population proportion is to be checked we use p hat
Correct answer is
d. H0 : pˆ = .6, Ha: pˆ > .6
Answer:
The survey shows that 20% of the individuals were satisfied with the car.
Step-by-step explanation:
- We are given that 2,300 people were surveyed.
- We are also given that 460 of those individuals would buy that car again.
- We need to find the percentage of individuals that were satisfied with the car.
When we need to find the percentage of a population, we can use the following formula:
We need to identify the part and the whole in this problem.
We are given that 2,300 people are surveyed, so this is the <u>whole</u> portion.
We are also given that 460 were satisfied, so this is the <u>part</u> portion.
Therefore, we can set up our fraction.
Now, let's solve the percentage.
Therefore, of those surveyed, 20% of the individuals were satisfied with the car.
Answer:
1 bag of chips cost $1.25
Step-by-step explanation:
total money spent minus cost of soda = price of 2 bags of chips
$4.00- $1.50 = $2.50
2 bags of chips divided by 2 = price for one bag
$2.50 / 2 = $1.25
Its approximately 7.1 inches. 2 inches plus 2 inches is 4 so its obviously not a. 12.3 is just too ridiculously big for the figure so its down to C and B.
since the rounded edge is bigger than the two inches, it wouldn't be B, which leaves you with C
Hope this helped you
