The director of health services is concerned about a possible flu outbreak at her college. She surveyed
100 randomly selected residents from the college's dormitories to see whether they had received a
preventative flu shot. The results are shown below. What is the probability that a dormitory resident
chosen at random from this group has had a flu shot, given that he is male?
A)51/100
B)39/100
C)39/80
D)13/17

Answers

Answer:

39/100

Step-by-step explanation:

The question asks to find the probability that a dormitory resident

chosen at random from this group has had a flu shot, given that he is male.

As for that, the first thing to do is to look at the column where it says male.

Male:

39-Had Flu Shot

12-Did not have Flu Shot

Since the question is asking for the total number of males who did get a flu shot, it would be 39.

Lastly, to find probability, you have to use part over whole. The part would be 39. The whole would be the number of people selected to be tested. Therefore, the whole would be 100. That is why the probability that a dormitory resident chosen at random from this group has had a flu shot, given that he is male would be 39/100.

Wednesday, #3 : 8x + 54

Step-by-step explanation:

8x + 54

Answer:

Tuesday, 1: 30 pounds

Tuesday, 2: 40% of the apples

Tuesday, 3: x ( or any variable) + 8

Tuesday, 4: 9a-3b

Step-by-step explanation:

Since she weighs 38% of the normal weight, you multiply the decimal form to the original weight, which is 78. So .38 multiplied by 78 is 29.64, and rounding it to the nearest pound would make it go up to 30.

38%=.38

.38 x 78=29.64

29.64 rounded = 30

If 3/5 of the apples are ripe, that means that 2/5 are not. An easy way to turn this fraction into a percent is to make the number out of 100. Since 5 x 20 is 100, you multiple both the numerator and denominator by 20. 2 x 20 is 40, 5 x 20 is 100, hence 40/100. The numerator will be the percentage.  

5/5-3/5 = 2/5

2/5 x 20/20 = 40/100

40/100 = 40%

The unknown score would become a variable, and since its increasing by 3 it is +8.

Since the perimeter is adding all sides, you'd add all of the equations. The 3a's times 3 would be 9a, and the -b would become -3b.

3a - b + 3a - b + 3a - b

9a - b - b - b

9a - 3b

Suppose the equation h =− 16t2 + 35t models the altitude a football will reach t seconds after it is kicked. Is it possible for the football to reach 16 ft in the air? Justify your answer.

Answers

Answer:

The ball will be able to reach the 16 ft.

Step-by-step explanation:

In order to calculate if the ball will be able to reach that height, we must make "h" equal to 16, if there's a real positive solution, then the ball will be able to reach it.

16 = -16t² + 35t

16t² - 35t + 16 = 0

t = [-(-35) +- sqrt((-35)² - 4*16*16)]/(2*16)

t = [35 +- sqrt(1225 - 1024)]/32

t = [35 +- sqrt(201)]/32

t = (35 +- 14.177)/32

t1 = 0.65071875

t2 = 1.5367

The ball will reach that height at 0.65 s and 1.53 s.
