Answer:
Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421
Step-by-step explanation:
We assume the following table:
No Hou. smokes >=1 hou. smokes Total
______________________________________________________
Student indicates he Cell 1 Cell 2 Cell 3
or she has asthma
_______________________________________________________
Student indicates he
or she does not have Cell 4 Cell5 Cell 6
asthma
_______________________________________________________
Total Cell 7 Cell8 1000
We are assuming a grand total of 1000 people for this case
Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421
The distance between the pitchers mound and home base is 18.44 meters
Interest calculated using the previous balance method is LOWER than the average daily balance method when large payments are made during the month.
The previous balance method is an accounting method where interest charges are based on the amount owed at the end of the beginning of the billing cycle.
Formula to find mean and standard deviation is,
Means = np and standard deviation =
.
Where n= sample size, p = probability.
According to the given problem, the probability that an individual has 20 vision is 0.19 in a class of 70 students. So,
p = 0.19 and n = 70.
Hence, the first step is to plug in these values in the above formula to get mean and standard deviation. Therefore,
Mean = np
= 70* 0.19
= 13.3
= 13.300 (Rounded to nearest thousandth.
Standard deviation = ![\sqrt{np(1-p)}](https://tex.z-dn.net/?f=%20%5Csqrt%7Bnp%281-p%29%7D%20%20)
=![\sqrt{70*0.19*(1-0.19)}](https://tex.z-dn.net/?f=%20%5Csqrt%7B70%2A0.19%2A%281-0.19%29%7D%20%20)
=![\sqrt{13.3*0.81}](https://tex.z-dn.net/?f=%20%5Csqrt%7B13.3%2A0.81%7D%20%20)
=√10.773
=3.282224855
= 3.282 (Rounded to nearest thousandth).
Answer:
8425/10.25
821.9
It would take about 822 hours
Step-by-step explanation:
Okay. so, to find the answer for this, you should set the equation as 10.25x = 8,425. "x" equals the number of hours. What you should do is divide each side by 10.25 to isolate the "x". When you do that 8,425/10.25, you get 821.951 and other numbers or 822 hours when rounded to the nearest whole number. x is approximately 822. You would have to work about 822 hours to earn $8,425.
