16 or more books sold in a day will include two intervals from the given table:
a) 16 - 20 books sold.
Probability = 0.201
b) 21 - 25 books sold.
Probability = ?
Since the table gives the probability distribution, the sum of all the probabilities must be equal to 1. We are given the probabilities of 4 out 5 intervals. So in order to find the probability of the 5th interval (21-25) we can subtract the sum of probabilities of rest of the intervals from 1.
So, P(21 - 25) = 0.019
In order to find the probability of 16 or more books sold we need to sum the probabilities of both these intervals.
So, the probability of 16 or more books being sold on a given day = 0.201 + 0.019 = 0.220
The total of all the taxes are 9% (0.09). so the formula to find her total cost is (original price x 0.09) + (original price). as you plug it in, it’ll look like this: (69 x 0.09) + (69) = 6.21 + 69 = 75.21
ANSWER: $75.21
Answer:
7+22i
Step-by-step explanation:
Since this is like a binomial, you have to apply the foil method
(-2+3i)(4-5i)=-8+10i+12i+15
(the 15 is the product of 3i*-5i)
Now, you combine like terms
-8+15=7
10i+12i=22i
so the expression in a+bi form is 7+22i

Answer:
(1 + √2)/2
Step-by-step explanation:
Assuming the values are in degrees,
sin(45) = sin(π/4)=√2/2
cos(60) = cos(π/3)=1/2
thus
sin(45) + cos(60) = √2/2 + 1/2 = (1 +√2)/2
