Answer:
15.12
Step-by-step explanation:
Cost of meal = $20
Discount (coupon) = 30%
Amount of discount = 30% of $20
= 30/100 * 20
= 0.3 * 20
= $6
Amount paid after discount= initial cost of meal - discount
= $20 -$6
= $14
Sales tax =8%
Amount of sales tax = 8% of $14
= 8/100 * 14
= 0.08 * 14
= $1.12
Total amount paid = Amount paid after discount + Amount of sales tax
= $14 + $1.12
= 15.12

Step-by-step explanation:
Given that researchers are studying the relationship between honesty, age, and self-control conducted an experiment on 160 children between the ages of 5 and 15.
a) The population is the children between the ages of 5 and 15 in general
D. All children between the ages of 5 and 15
b) Sample is
D. 160 children between the ages of 5 and 15
c) Yes becauB. If the sample is randomly selected and representative of the entire population, then the results can be generalized to the target population. Furthermore, since this study is experimental, the findings can be used to infer causal relationships.se randomly selected and also sample size is above 30
Given:
The expression is
To find:
The product of prime polynomials which is equivalent to the given expression.
Solution:
We have,
Taking out the common factors, we get
It can be written as
