22. P(n > 3) = P(4)+P(5) = (4+5)/30 = 9/30 = 3/10
23. The game isn't fair because there as many even numbers as there are odd numbers on a die. You get double the points he gets at the same chance!
Answer:
The proportion of temperatures that lie within the given limits are 10.24%
Step-by-step explanation:
Solution:-
- Let X be a random variable that denotes the average city temperatures in the month of August.
- The random variable X is normally distributed with parameters:
mean ( u ) = 21.25
standard deviation ( σ ) = 2
- Express the distribution of X:
X ~ Norm ( u , σ^2 )
X ~ Norm ( 21.25 , 2^2 )
- We are to evaluate the proportion of set of temperatures in the month of august that lies between 23.71 degrees Celsius and 26.17 degrees Celsius :
P ( 23.71 < X < 26.17 )
- We will standardize our limits i.e compute the Z-score values:
P ( (x1 - u) / σ < Z < (x2 - u) / σ )
P ( (23.71 - 21.25) / 2 < Z < (26.17 - 21.25) / 2 )
P ( 1.23 < Z < 2.46 ).
- Now use the standard normal distribution tables:
P ( 1.23 < Z < 2.46 ) = 0.1024
- The proportion of temperatures that lie within the given limits are 10.24%
Answer:the answer to your question is 6 feet Im pretty sure
Step-by-step explanation: so if it is a 15 foot board and it is at a 40 degree angle you have to multiply 4 by 1.5 to get your answer. Hope this helps.
Answer:
(A)3,500 + 0.06x > 4,000 + 0.04x
Step-by-step explanation:
<u>Jose's Earnings</u>
Monthly Salary = $3,500
6% commission on his sales, x =0.06x
Total = 3500+0.06x
<u>Maris' Earnings</u>
Monthly Salary = $4,000
4% commission on her sales, x =0.04x
Total = 4000+0.04x
If Jose's earnings be greater than Maris' earnings, then:
3500+0.06x > 4000+0.04x
Answer:
59280
Step-by-step explanation:
the club has 40 members so n=40, they want to choose people to fill 3 positions so r=3
put the values of n and r into your equation at the bottom to get 59280
