Answer:
The cumulative frequency of the 210-240
class is 72
Step-by-step explanation:
Here we want to get the cumulative frequency of the 210-240 class.
What we will do here is to add the values of the frequency up to that point.
Mathematically, that would be;
4 + 18 + 30 + 20 = 72
To find the median you arranged the data from least to greatest.
0.48. 0.66. 0.7. 0.82. 0.94. 1.02.
The number in the middle is the median so it would be between 0.70 and 0.82
Which is = 0.76
Let X = the distance you need to find.
Using the Pythagorean Theorem we can solve for x
x = SQRT( 500^2 - 300^2)
x = SQRT (250,000 - 90,000)
x = SQRT(160,000)
x = 400
It is 400 yards
The perimeter of the shaded region is 8π cm and the area of the shaded region is 32(π - 2) cm² or 36.53 square cm.
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have shown a square in which a one-fourth circle is shown and making an ellipse.
The perimeter of the circle = 2πr = 2π(8) = 16π cm
The perimeter of the one-fourth is circle = (16π)/4 = 4π cm
The perimeter of 2 one-fourth circle = 2(4π) = 8π cm
The area of the one-fourth circle = (1/4)πr² = (1/4)π(8)² = 16π square cm
The area of the right-angle triangle = (1/2)(8)(8) = 32 square cm
The area of the shaded region = 2(16π - 32) = 36.53 square cm
or
= 32(π - 2)cm²
Thus, the perimeter of the shaded region is 8π cm and the area of the shaded region is 32(π - 2) cm² or 36.53 square cm.

No you add them all together and then you divide the number of GPA's to get the mean. You go from greatest to lowest to figure out the median and to find the mode excepts my mind. <span />
