Answer:
A. 1,120 miles
Step-by-step explanation:
<em>25/28 = 1000/x (Solve for x by cross multiplying)</em>
<em>28000 = 25x ( 28000 / 25 = 1120)</em>
<em>1120 = x</em>

Answer:
We can reject the null hypothesis. There is significant evidence that p<0.31 at α = 0.01
Step-by-step explanation:
To test the the claim p < 0.31, null and alternative hypotheses are:
: p=0.31
: p<0.31
For α = 0.01, one tailed test critical value is -2.33
For z=-3.36 , p value is ≈ 0.0004
Since p-value<significance level (0.0004<0.01), we can reject the null hypothesis. There is significant evidence that p<0.31 at α = 0.01
Since each odd (or even) is two greater than the previous number, two consecutive such numbers are n and n+2.
The we are told that the sum of two such number is 100, so we can say:
n+n+2=100 combining like terms on the left side you get:
2n+2=100
....
to solve, if you were interested...subtract 2 from both sides
2n=98 divide both sides by 2
n=49
So the two odd numbers are 49 and 51
