Answer:
1824 square inches
Step-by-step explanation:
First, separate the figure into two sections. The triangle on top, and the rectangle on the bottom.
to get the area of the triangle, simply multiply height times width and divide by two.
48 x 12 = 576
576/2 = 288
the area of the triangle is 288 sq in
next, multiply the height and width of the rectangle to get its area.
32 x 48 = 1536
add 1536 to 288 to get the area of the complete figure
1536 + 288 = 1824
the answer is 1824 square inches
Answer:
3) (98.08, 124.16)
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 111.12
Standard deviation = 13.04
Calculate an interval that is symmetric around the mean such that it contains approximately 68% of fines.
68% of the fines are within 1 standard deviation of the mean speed. So
From 111.12 - 13.04 = 98.08 to 111.12 + 13.04 = 124.16
The interval notation in the smallest value before the highest value.
So the correct answer is:
3) (98.08, 124.16)
