Answer:
c
Step-by-step explanation:
(12 x 120)/ 3.87 x 3.35=c
Answer:
The estimate of the proportion of people who pass out at more than 6 Gs is 0.279.
Step-by-step explanation:
Estimate of the proportion of people who pass out at more than 6 Gs.
Number of people who passed out divided by the size of the sample.
We have that:
Sample of 502 people, 140 passed out at G forces greater than 6. So the estimate is:
The estimate of the proportion of people who pass out at more than 6 Gs is 0.279.
The equation will have the form y=ax+b. a is the slope, and b is the y value at x=0.
The slope is -2 (that's our a), which you can see from the two given points. If x progresses from -3 to -2, y goes from 3 to 1. At x=0, the line crosses through y=-3 (that's our b)
So our generic form y=ax+b for this line is y=-2x-3
Step-by-step explanation:
The area of circle with radius 4cm is,
area of circle = π r *r = 3.14 * 4 * 4
= approx 50.27
The area of circle with radius 2cm is,
area of circle = π * r * r = 3.14 * 2 * 2
= approx 12.57
The circles are concentric means they have a common Centre, so,
Area between the two circles = area of bigger circle - area of smaller circle
= 50.27 - 12.57
= 37. 7 sq. cm
