2.5 x 2 is 5, so if he travels at the same rate, you must increase the miles by the same amount. So in this case its 180 x 2, which is 360.
Alright, lets get started.
Mari adds 4 spoons of honey to a pitcher.
Each spoonful holds 5 mL of honey.
So, total ML of honey mari adds = 4 spoon * 5 ML = 20 ML
Answer : 20 mL of honey does Mari have in all.
Hope it will help :)

Answer:
I don't know this question what am I do for this question
Answer:
By using hypothesis test at α = 0.01, we cannot conclude that the proportion of high school teachers who were single greater than the proportion of elementary teachers who were single
Step-by-step explanation:
let p1 be the proportion of elementary teachers who were single
let p2 be the proportion of high school teachers who were single
Then, the null and alternative hypotheses are:
: p2=p1
: p2>p1
We need to calculate the test statistic of the sample proportion for elementary teachers who were single.
It can be calculated as follows:
where
- p(s) is the sample proportion of high school teachers who were single (
) - p is the proportion of elementary teachers who were single (
)
- N is the sample size (180)
Using the numbers, we get
≈ 1.88
Using z-table, corresponding P-Value is ≈0.03
Since 0.03>0.01 we fail to reject the null hypothesis. (The result is not significant at α = 0.01)
