In a certain year, exactly 1,481 fewer women than men applied to U.S. medical schools. If 29,250 men applied, what was the total
Oxana [17]
The total number of people who applied to U.S. medical schools this year would be 57,019.

29,250 - 1,481 = 27,769
29,250 + 27,769 = 57,019

the average number of chocolate chips in a particular brand of chocolate chip chewy cookie is 19. the standard deviation is 2.6.
zzz [600]

The probability illustrated shows that the

percent of cookies would have between 13.8 and 24.2 chips is 95.44%.

<h3>How to calculate the probability?</h3>

It is important to note that the requirement to solve the probability between z-values is to know that the probability between the z-values is the difference between the probability of the greatest z-value and the lowest z-value.

This will be illustrated thus:

Z value for 13.8, z =(13.8-19)/2.6 =-2

Z value for 24.2, z =(24.2-19)/2.6 = 2

P( 13.8<x<24.2) =P(-2<z<2)

=P( z <2 –P(z < -2)

=0.9772 -0.0228

=0.9544

= 95.44%

The percent is 95.44%.

In-s [12.5K]

Answer:

The null hypothesis will be that the average annual donor income is less or equal to $ 100,000

Step-by-step explanation:

The claim is mostly treated as alternate hypothesis .

In this question the claim is given as the average annual donor income has increased therefore it is written as

Ha: u > 100,000

The null hypothesis is reverse of the alternate hypothesis

H0: u ≤ 100,000

The null hypothesis will be that the average annual donor income is less or equal to $ 100,000

Jeff and Mike are playing both playing
zalisa [80]
Jeff has about 46.43% left and smile had about 39.29% left.

I got this by putting the number of levels that had left in a fraction over the total number of levels aka 28. I then wrote that that fraction was equal to x/100 where x would be the percentage. I divided 100 by 28 to see how to get from 28 to 100 if we multiplied. I then took the answer from that and multiplied the number of levels left by that number (3.571428571428571) and rounded to the nearest hundredth.
