Answer:
percentage change=25% .
Step-by-step explanation:
Given : $15.60 to $11.70 .
To find: What is the percent change .
Solution: We have given that $15.60 to $11.70 .
Change = final value - initial value .
Change = $15.60 - $11.70
=$3.9
percentage change = 
= 
= 
.
On dividing both number by 3
percentage change=
.
percentage change=
.
percentage change=25% .
Therefore, percentage change=25% .

Step-by-step explanation:
Answer:
0.7361
Step-by-step explanation:
In this question we have
number to be 10
Then we have a probability of 10% = 0.10
We have q = 1-p
= 1-0.10 = 0.90
Then the probability of not more than 1 being defective:
P(x=0) + p(x= 1)
(10C0 x 0.1⁰ x 0.9^10-0)+(10C1 x 0.1¹ x 0.9^10-1)
= 1 x1 x0.3487 + 10 x 0.1 x 0.3874
= 0.3487 + 0.3874
= 0.7361
This is the the required probability and this answers the question.
probability = 10 percent = 0.1
q= 1- 10percent = 90% = 0.9
n = 4
To get the required probabiltiy for this question is
P(not greater than one is defective )=P(x=0)+P(x=1)
= 4C0x(0.1)⁰x(0.9)⁴+4C1x(0.1)¹x(0.9)³
= 0.9477
The required probability is 0.9477
