Answer:
a) P(Y=10)=0.0013
b) P(Y≤5)=0.00000035
c) Mean = 17.5
S.D. = 2.29
Step-by-step explanation:
We can model this as a binomial random variable with n=25 and p=0.7.
The probability that k students from the sample are foreign students can be calculated as:
a) Then, for Y=10, the probability is:
b) We have to calculate the probability P(Y≤5)
c) The mean and standard deviation for this binomial distribution can be calculated as:
Add the things in the bracket first so
2+2 = 4
then you do the 8 ÷ 2 = 4
then you multiply them together. this is because the number next to the bracket has a hidden multiply sign so
4 x 4 = 16
answer is 16
Answer:
Option d is correct that is range of the function is all multiples of 10 between 150 and 400, inclusive.
Step-by-step explanation:
We have been given the information that gretta is selling x raffle ticket by a function
f(x)=10 x
Range is the values that y takes in a particular function
Here, we will get any value which is multiple of 10 since we have a function 10 times of something whatever value we put for x we will get multiple of 10.
Hence, Option d is correct that is range of the function is all multiples of 10 between 150 and 400, inclusive.

Answer:
The correct option is C
Step-by-step explanation:
Generally
stand for Mean Square Between which the mean calculated based on the difference between the sample means
While
stands for Mean Square Within which the mean calculated based on the difference between the elements within the set(group)
Thus
The measures the differences related to the treatment given to each sample. The measures the differences related to entries within the same sample.
