The weights of 1,000 men in a certain town follow a normal distribution with a mean of 150 pounds and a standard deviation of 15 pounds.From the data, we can conclude that the number of men weighing more than 165 pounds is about , and the number of men weighing less than 135 pounds is about .
Answers
z = ( 165 - μ ) / σ = 1
P (x < 135) = P (z < -1) = 0.1587
P (165 < x) = P (1 < z) = 0.1587
.187 * 1000 = 187 more than 165
.187 * 1000 = 187 less than 135
Answer:
z = ( 135 - μ ) / σ = -1
z = ( 165 - μ ) / σ = 1
P (x < 135) = P (z < -1) = 0.1587
P (165 < x) = P (1 < z) = 0.1587
.187 * 1000 = 187 more than 165
.187 * 1000 = 187 less than 135
1000 / 187 =5.34

B) D = (all real numbers}
C) D = {rational numbers}
D) D = {all whole numbers}
Answers
Answer:
Option: D is the correct answer.
D) D = {all whole numbers}
Step-by-step explanation:
As we could see that the number of deer i.e. the population of the deer is based on the number of bobcats in an area.
As the number of bobcats can't be negative or in a fraction or negative it will always be in a whole number (i.e. 0 represents that there are no bobcats, 1,2,.....)
Hence, the correct domain for the function is:
D) D = {all whole numbers}

You intend to ride all of the rides exactly one time each on your trip to Forest Heights Park. Which would be least expensive: pay separately or buy the all day pass?
(Points : 1)
Pay Separately
All Day Pass
Answers
If the group all together is only being charged once per ride, and the whole group is going twice, then you will double the cost of each ride:
4.50 x 2 = 9
4 x 2 = 8
3.50 x 2 = 7
In total, the rides will cost $24. So, if you're paying with a $100 bill, you will receive $76 in change.
2.2 The answer is 58.
You will do the same procedure as the first question, but this time multiply the costs by 3.
5.50 x 3 = 16.5
2 x 3 = 6
6.50 x 3 = 19.5
The total will be 42. Subtracted from 100, you will get 58.
3.3 The answer is 2.
If you have 15 dollars and the coaster costs 5.50, the first time you ride it you will have 9.50 left. The second time, you will have 4 dollars left, and then you will not be able to pay for a third time.
4.4 The answer is 23.25
If you add up all the correlating costs of the tickets (6.75 + 4.50 + 4.50 + 10.50 + 10.50), you will get 36.75. Then you must subtract that from 60, which will give you 23.25 dollars in change.
5.5 The answer is 54.75
You will do the same procedure here as you did above. Add the corresponding costs together (you're done after this part, because the question isn't asking for how much change you'll receive).
6.6 The answer is 7.
If the tickets cost $10.50 and you have $80, then you want to divide 80 by 10.50. You will get 7.6. Since you can't buy a sixth of a ticket, your answer will be 7.
7.7 The answer is to pay separately.
In this question, you will add all the costs together (except the day pass) and compare it to the cost of the day pass. Once you add all the costs together, you will get 17.50. This is cheaper than the day pass, which is 19.95.
