There are 24 possible answers, 6 are correct answers and 18 are incorrect answers. By use of the hypergeometric distribution the probabilities of each possible number of randomly selected correct answers can be found, as follows:
P(0) = 0.1379, P(1) = 0.3819, P(2) = 0.341, P(3) = 0.1213, P(4) = 0.017, P(5) = 0.0008, P(6) = 0.000007.
The expected or mean number of correct answers is found from:
The answer is: 1.4998
Answer:
75000
Step-by-step explanation:
We can use ratios to solve. Put the scale length over the real length
1 15
------------ = ----------------
5000 x
Using cross products
1x = 15*5000
x =75000
Y=mx+b
m=slope b=yintersept
first you find b by plugging in the slope and the two points
3=(2)7+b
3=14+b
-11=b
now that you have the y intercept you can plug the y intercept and the slope in
y=2x-11
Answer:
24 terminal zeros
Step-by-step explanation:
Here, we want to know the number of terminal zeros that the product if the integers above has
Terminal zeros refer to the zeros at the right of the last non zero digits
The product we are dealing with is;
80^16 * 75^8
80^16 itself has 16 terminal zeros
while 75^8 should have 8 terminal zeros
So the total number of expected terminal zeros is simply the addition of both terminal zeros and that gives 16 + 8 = 24 terminal zeros
