Answer:
Area = 55 cm2
Step-by-step explanation:
It the base of the parallelogram was 9 centimeters and increased by 2, the new base has 9 + 2 = 11 centimeters.
It the height of the parallelogram was 4 centimeters and increased by 1, the new base has 4 + 1 = 5 centimeters.
Now, we can calculate the area of the parallelogram using the formula:
A = b * h
Where A is the area, b is the base and h is the height. So:
A = 11 * 5 = 55 cm2
Answer:
Mean= $21.5067
Median = $15.8
Standard deviation= $19.02
Coefficient of skewness= $0.8991
Step-by-step explanation:
Mean =( $4.0 +$6.0 +$7.4+ $10.6 +$12.5+ $13.6+ $15.4+ $15.8 +$16.8
+$17.4+ $19.1 +$22.3+ $37.1 +$43.2 +$81.4)/15
Mean =$ 322.6/15
Mean= $21.5067
Median= middle number
Median = $15.8
Variance=( ($4.0-.$21.5)²+( $6.0. -.$21.5)²+( $7.4 -.$21.5)²+( $10.6 -.$21.5)²+( $12.5 -.$21.5)²+( $13.6. -.$21.5)²+ ($15.4 -.$21.5)²+( $15.8 -.$21.5)²+ ( $16.8 -.$21.5)²+ ($17.4-.$21.5)² +($19.1 -.$21.5)²+ ($22.3 -.$21.5)²+ ($37.1 -.$21.5)²+ ($43.2-.$21.5)²+( $81.4-.$21.5)²)/15
Variance=$ 5424.79/15
Variance=$ 361.65
Standard deviation= √ variance
Standard deviation= √361.65
Standard deviation= $19.02
Coefficient of skewness
=3( mean-median)/standard deviation
= 3(21.5-15.8)/19.02
= 3(5.7)/19.02
= 17.1/19.02
Coefficient of skewness= 0.8991
Answer:
The given expressions x+3(7-x) and x+21-3x are equivalent by using the distributive property
Step-by-step explanation:
Given expressions are x+3(7-x) and x+21-3x and also given that they are equivalent
To find for what property the given two expressions are equivalent :
x+3(7-x)=x+3(7)+3(-x)
=x+21-3x ( here we are using the distributive property a(x+y)=ax+ay )
Therefore the given expressions x+3(7-x) and x+21-3x are equivalent by using the distributive property
First you would add up all four tests scores and then divide the final answer by 4 because there was a total of four tests. Therefore Alexandria can get a score of 79.5% or higher is she wants to average with an 80% on all tests. Hope this helps.
