Not necessarily . For example a large number might be a multiple of 2 large prime numbers. For example 654,481 is 809^2 * 809 is prime) so this has only 2 factors. 6 has more factors than 654,481.
2b+15
2 dollars for each book so you multiply it by the number of books and add 15 because it is a one time fee.
Answer:
Step-by-step explanation:
the amount of peanuts given was 3/5th of a pound of peanuts.
there are 6 people amongst which this amount should be divided equally.
therefore given amount should be divided by 6 so that each person gets an equal share
amount present - of a pound
divide by 6
then numerators are multiplied by numerators and denominators multiplied by denominators
the fraction can be further simplified by dividing both numerator and denominator by common number which is 3
=
therefore fraction that each person receives is 1/10th of a pound
Answer:
a)
b) t=1.172
c) The null hypothesis failed to be rejected.
There is no enough evidence to claim that the mean tornado length is greater than 2.4 miles.
Step-by-step explanation:
<em>The question is incomplete:</em>
<em>The sample mean is 2.74 and the sample standard error is 0.29.</em>
We have to test the claim that the mean tornado length is greater than 2.4 miles.
The appropiate null and alternative hypothesis are:
As the population standard deviation is not known, the sample standard deviation is used as an estimation. The statistic is T-student instead of the z-value.
The degrees of freedom are
The P-value for this t-statistic is
At a significance level of 0.05, the P-value is greater, so the effect is not significant and the null hypothesis failed to be rejected.
There is no enough evidence to claim that the mean tornado length is greater than 2.4 miles.
