If 60% out of the 2,660 students are males, then
40% out of t<span>he same 2,660 students are females
Ten the number of females is 40% x 2660 = 0.4 x 2660 = 1,064 females</span>
Answer:
μ = 1 The firm expects that one oil exploration will be successful.
v(x)= 0.9
Step-by-step explanation:
The first step is to define the random variable x as:
x: number of oil explorations being succesful
Then x can be take this values:
x = 0 , x =1 ... x =10
x is a binomially distributed random variable with parameters.
p = 0.1 and n=10
And the mean or the expected value of x is:
μ = E(x) = np
Then μ = 10*0.1 = 1
And the variance of x is:
V(x) = np(1-p)
V(x) = 10(0.1)(1-0.1)= 0.9
Answer:
the answer is 11/21 or 0.523809524

Step-by-step explanation:
Answer:
see attached
Step-by-step explanation:
The cosine function crosses the midline at x = pi/2 = 1.57, so point (pi/2, 0) will be on the graph. It has a peak at x=0. The vertical scale factor of 4 mean the peak is (0, 4).
Your sine tool will be able to plot the graph using these two points.
__
If you need a maximum or minimum that is to the right of the midline point, you can use the minimum at (pi, -4) = (3.14, -4).
Graph A
it shows two points for each x, meaning its not a function.
