The area is 120 and the perimeter is 44.
Explanation: To find area, you have to do length times the width. The length would be 10 because the 12 inches on the bottom is not a straight line. So you would just multiply 10 and 12 and get 120. For perimeter, you add 10 and 12 two times. So it would look like this: 10+12+10+12=44. I know I explained it a lot but hope this was helpful.

Answer:
Probability = 0.0288
Step-by-step explanation:
For the first draw.
There are total of 52 cards in a deck of cards and a total of 26 red cards in a deck of cards.
Probability of drawing a red= 26/52
Probability = 0.5
For the second draw. Actually the initial card drawn was replaced. Total number of face cards are 12.
Probability of drawing a face card = 12/52= 0.23076923
For the third draw .
There are 13 diamond cards in total.
Probability of a diamond = 13/52
Probability = 0.25
Probability of red,face, diamond= 0.5*0.23076923*0.25=0.028846
To four decimal place = 0.0288
Answer:
Step-by-step explanation:
Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.
We can find sum of all 16 test scores = 84(16) = 1344
Outlier found = 78
If outlier is removed new sum = 1344-78 = 1266
Number of entries without outlier = 15
New average = 1266/12 =84.4
We find that average of new data increases.
Also whenever we remove outlier std deviation also would be reduced.
