Step-by-step explanation:
The formula of an area of a trapezoid:
b₁, b₂ - bases
h - height
We have b₁ = 10in, b₂ = 5in and h = 11in. Substitute:
Answer:
d
Step-by-step explanation:
Radius = 4
area:
4x4x3.14x12=602.88
To calculate the IQR, we need the radian, which is the middle number of each column, namely (86,82) for each exam.
Above the middle number, we have 5 values. The middle value (of the upper part) is Q3, which is on the third line, or (92,85).
Below the middle number, we also have 5 values. The middle (of the lower half) is Q1, which is on the 9th line (80,78)
The IQR is the difference between Q3 and Q1, namely
(92-80, 85-78) = (12, 7)
Since 12>7, we conclude that the IQR of the mid-term is higher than the final.
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0)
Since you know m = 2, you can plug it into the equation
y = mx + b
y = 2x + b
To find "b", plug in the point (2,4) into the equation
y = 2x + b
4 = 2(2) + b
4 = 4 + b Subtract 4 on both sides
0 = b
y = 2x + 0
y = 2x
