Answer:
444
Step-by-step explanation:
375 - 47 = 328
328 + 116 = 444
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:
It would be .3 i think if you are talking about scientific notation :)

The machine gun and the tank were new technologies that influenced WW1 the most. The machine gun lengthened the war and forced it to become a trench war. The bullets in a machine gun could shoot 500 bullets per minute therefor making it much more difficult for the rivalry county to fight back.
Answer:
y ≥ 3x -1; x +3y ≤ 6
Step-by-step explanation:
Both lines are solid, so the only viable choices are those with "or equal to" in the comparison operators: the 2nd and 4th choices.
The line with a slope of +3 is shaded <u><em>above</em></u> the line, so that will correspond to the inequality ...
y ≥ 3x -1 . . . . . . . . . . found only in the 4th choice.
