This is calculator work. Type in 0.8 inverse tangent and find 38.6598, which, rounded, matches answer D.
<span>Consider the solid s described below. the base of s is the region enclosed by the parabola y = 5 - 5x2 and the x-axis. cross-sections perpendicular to the x-axis are isosceles triangles with height equal to the base. find the volume v of this solid.</span>
Answer:
The slope is 2
Step-by-step explanation:
The formula to find slope is y2-y1/x2-x1
Plug in the numbers and you get: 5-3/1-2
The result of that is -2/-1 which can be simplified to 2
Answer:
68.269%
Step-by-step explanation:
We start by calculating the z-scores of both numbers
Mathematically;
z-score = (x-mean)/SD
where x represents the raw score
For 82;
z-score = (82-87)/5 = -5/5 = -1
For 92;
z-score = (92-87)/5 = 5/5 = 1
So the probability we want to calculate would be;
P(-1 < x< 1)
We can use the standard normal distribution table to get this.
By using the distribution, P(-1<x<1) = 0.68269
By converting this to percentage, we have 68.269%
