Congruent Angles have the same angle (in degrees or radians). That is all. They don't have to point in the same direction. They don't have to be on similar sized lines.
Answer:
a. Yes
See explanation below.
Step-by-step explanation:
Assuming that if the question is if we can use the normal approximation for the true proportion.
For this case we have n = 40 and p = 0.3 (probability of success)
We need to check some conditions:
1) Random sample : This condition is satisfied since the problem says that she randomly select 40 records
2)
3) 10% condition: the random sample is assumed to be less than 10% of the original population size (assumed)
The population proportion have the following distribution
So then as we can see the normal approximation for this case makes sense since we have all the 3 conditions satisfied so then the answer would be:
a. Yes
Remark
First you have to find out how much the 18% tip is.
Step One
Find the 18% tip.
64 * 18/100 = 1152/100 = 11.52 dollars.
Step Two
What is the bill total
The total for the bill is 64 + 11.52 = 75.52
Step Three
Calculate the change.
<u>Formula</u>
Change = 100 - the cost of the meal
<u>Solve</u>
Change = 100 - 75.52
Change = 24.48 Answer
Answer:
$87.5
Step-by-step explanation:
Original price also means COST PRICE
C.P=$50
S.P=75% of $50-$50
To find the sale price it will be 75% of C.P -C.P
75% × $50 + $50= 0.75 × $50-$50
=$37.5-$50.
= $12.5
therefore the sale price is $12.5
