Answer:
36
Step-by-step explanation:
Here's a little rhyme my Mom used to tell me to help me remember:
6 times 4 is 24
6 times 6 is 36
6 times 8 is 48
Hope this helps :)
Answer:
P (X≤1) = 0.000
Step-by-step explanation:
Data given:
p = 79% = 0.79
q = 1 - 0.79 = 0.21
n = 16
P (no more than 1 in 16 adults) = P (X≤1)
P (X≤1) = P (X=0) + P (X=1)
We can find the probability by using binomial functions:
<h3>P(X=0):</h3>
P(X=0) = (16! / 0!(16-0)!) · 0.79⁰ · 0.21¹⁶
Use calculator to solve:
P(X=0) = 0.000000000798
<h3 /><h3>P(X=1):</h3>
P(X=1) = (16! / 1!(16-1)!) · 0.79¹ · 0.21¹⁵
Use calculator to solve:
P(X=1) = 0.000000034506
<h3>P(X≤1)</h3>
P (X≤1) = P (X=0) + P (X=1)
P (X≤1) = 0.000000000798 + 0.000000034506
P (X≤1) = 0.00000003530
P (X≤1) = 0.000
As 1 is a very low number, its probability is very small
<span>There are 60 seconds in a minute.
To find out how many copies in a second, divide 36 by 60.
That is 0.6
Then you would calculate to see how much in 15 seconds,
0.6 times 15
9 copies in 15 seconds
then multiply 36 * 4 to see how many in minutes
144 copies in 4 minutes
153 copies in 4 minutes and 15 seconds.
Hope this helps :)

He got 30 right
(40 x 75)/100
= 3000/100
= 30
