Answer:
The expected number of defective batteries to be pulled out is 0.9, which rounded to the nearest integer gives a total of 1, that is, 1 of the 3 batteries is expected to be defective.
Step-by-step explanation:
Given that a box contains 3 defective batteries and 7 good ones, and I reach in and pull out three batteries, to determine what is the expected number of defective batteries, the following calculation must be performed:
3 + 7 = 100
3 = X
10 = 100
3 = X
3 x 100/10 = X
300/10 = X
30 = X
3 x 3/10 = X
0.9 = X
Therefore, the expected number of defective batteries to be pulled out is 0.9, which rounded to the nearest integer gives a total of 1, that is, 1 of the 3 batteries is expected to be defective.
72*10=720 so all the numbers would need to add to 720
the median is 74 so you need to have both 75 and 76 in the set
the mode is 68 so that need to be in at least twice
and the range is 21 so the largest number-21=smallest number
57, 68, 68, 68, 75, 76, 76, 77, 77, 78
Answer:
3
Step-by-step explanation:
You divide 45 and 60 then you mutliple the number by 4 then find your anser after you done sovled this is how you solve it divided by 60=0.75 mutiply by 4=3 3 or 4/3
Answer:
10
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Let the base function be</u>
<u>It has the vertex at (3, -3), so it is translated 3 units right and 3 units down:</u>
It has zero's at (2, 0) and (4, 0)
<u>Substitute and solve for a:</u>
- a(x - 3)^2 - 3 = 0
- a(2 - 3)^2 = 3
- a = 3
or
<u>So the function is:</u>
