Answer:
9%
Step-by-step explanation:
Let the required number be 100.
Now, according to the question, the number is first increased by 30 %
⇒ 100 + 30 % of 100
⇒ 100 + [(30*100)/100]
⇒ 100 + 30
⇒ 130
Then, it is decreased by 30 %
⇒ 130 - (30 % of 130)
⇒ 130 - [(30*130)/100]
⇒ 130 - 39
⇒ 91
Net Decrease = 100 - 91
= 9
Percent Decrease = (Change in number*100)/100
⇒ (9*100)/100
= 9 %
Step-by-step explanation:
We have 8y + 5 <= 37.
Therefore 8y <= 32 (subtract 5 both sides)
y <= 4 (divide 8 both sides)
Answer:
a. the probability that any one of the computers will require repair on a given day is constant
Step-by-step explanation:
The following properties must be true in order for a distribution to be binomial:
- A fixed number of trials (125 computers)
- Each trial is independent of the others (one computer requiring repair does not interfere with the likelihood of another requiring repair).
There are only two outcomes (requires repair or do not require repair)
The probability of each outcome remains constant from trial to trial (All computers have the same likelihood of requiring repair, 0.15).
Therefore, the alternative that better fits those properties is alternative a. the probability that any one of the computers will require repair on a given day is constant
Answer:
108 feet²
Step-by-step explanation:
Well we can just multiply the corresponding sides of Quadrilateral ABCD to fit Quadrilateral EFGH.
Line EF is 42 feet
Line FG is 18 feet
Line GH is 18 feet
Line HE is 30 feet
The perimeter of Quadrilateral EFGH is
30+18+18+42=
30+36+42=
66+42=
108 feet²
