Answer:
.625
Step-by-step explanation:
Since the amount of pieces are 8, and you gave 5 away, you have to divide 5 by 8. This gives you .625
domain refers to the X values so option A would be correct :)
X-7/5 = -2
x- 7 = -10
x = -3
The number is -3
Answer:
-3x^4 - 14x^3 + 3x^2 - 10
Step-by-step explanation:
Answer: 0.3741
Step-by-step explanation:
Poison probability ;
P(x) = [U(^x) e(^-U)] ÷ x!
Where U = mean
Note: e = exponential symbol
Number of checks that year = 171
Number of days in a year = 365
U = 171/365 = 0.468
Average checks per day = 0.4685
Probability that at least one check was written per day is can be calculated by;
P(not 0) = 1 - P(0)
Therefore,
P(x) = [U(^x) e(^-U)] ÷ x!
P(0) = [ 0.4685^0 * e^-0.4685] ÷ 0!
P(0) = [ 1 * 0.6259] ÷ 1
P(0) = 0.6259
Therefore,
P(not 0) = 1 - 0.6259 = 0.3741
