Answer:
Probability = 0.0228
Step-by-step explanation:
Let X be a random variable which is a measure of the time to get a passenger on board.
Mean(u) = 22.5mins
Standard deviation (s) = 5.25mins
X = 33mins
From Pr(X>33), starting from Pr(X = 33)
For normal distribution, Z = 7(X - u) /s
Z= (33 -22.5) /5.25
= 10.5/5.25
= 2
From the normal distribution table, 2 = 0.4772
Recall that
If Z is positive,
Pr(x>a) = 0.5 - table value
Pr(x<a) = 0.5 + table value
Therefore;
Pr(X>33) = 0.5 - 04772
= 0.0228
30 * 1/5 = 6 so 6 have a cell phone
1/2 * 6 = 3 so 3 have a cellphone and social media
195 divide by 2 1/2
195 divide 5/2 (copy dot flip)
195 * 2/5
78 loads of laundry
19.99 divide by 78
.256
.26
he is paying 26 cents for each load
Answer:
1
Step-by-step explanation:
When the same quantities are being divided then the result is 1
2 ÷ 2 = 1
- 3 ÷ - 3 = 1
so
- 
÷ - = 1
The number may be calculated as (0.79)^4 = 0.3895 ≈ 0.400.
This is becasue the probability of finding each adult having health insurance is independent of others.
When, events are independent, the combined probability is the product of each probability =>
Probailibty of one adult with healt insurance * probability of one adult with healt insurance * probability of one adult with health insurance * probability of one adult with health insurance = 0.79 * 0.79 * 0.79 * 0.79 = (0.79)^4.
Answer: 0.400
