Answer:
5 SHOULD BE THE ANSWER SORRY FOR ALL CAPS
The shaded region is a parallelogram.
The formula for the area of any parallelogram is
.
The base of the parallelogram is 2 meters long (given).
The height of the parallelogram is 9 meters (do not be fooled by the unnecessary information of 14 meters)
The height is 9 meters because the height has to be perpendicular to the base. Thus, the side length must be 9 meters.
Multiply them together.
The area of the parallelogram is 18 square meters.
ANSWER
D. A'(-5,0), B'(0,9) and (2,6)
EXPLANATION
The coordinates of triangle ABC are A(0,-5), B(-9,0) and C(-6,2).
A rotation of 90° clockwise about the origin has the mapping,
Therefore the image triangle has vertices
A'(-5,0), B'(0,9) and C'(2,6)
The correct choice is D.
First let's find the result of the sum:
30 + 40 + 70 = 140
Now let's review the operations of each one:
Jillian added 30and40and then 70:
30 + 40 = 70
70 + 70 = 140
Samuel added 30 and 70 and then 40
30 + 70 = 100
100 + 40 = 140
answer
both are correct.
Conclusion: the order of the factors does not alter the product.
Answer: (22.41, 25.59)
Step-by-step explanation:
The t-critical value with 17 degrees of freedom for a 95% confidence interval is : 2.11
Sample mean = 24
Standard deviation = 3.2
Standard error of mean = s / √ n
Standard error of mean = 3.2 / √ 18
SE = 3.2/4.2426
Standard error of mean 0.7542
Confidence interval 24-(0.7542)(2.11) = 22.41 and
24+(0.7542)(2.11) =25.59
