Answer:
Step-by-step explanation:
This will form a hollow circular part of a cylinder of outer radius 7cm and inner radius 3cm
Area of a circle is given by πr^2.
Then, the big circle of radius 7cm
Area= πr^2
Area=22/7×7×7
Area =154cm^2.
Area of the circle of radius 3cm
Area= πr^2
Area=22/7×3×3
Area =28.286cm^2.
Area of the shaded part becomes
Big area - small area
154-28.286
Area of shaded part = 125.7143cm^2
Then to the nearest hundredth
Area of shaded part =125.71cm^2

Answer:
C. Uniform distribution
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that X is between values c and d, in which d is greather than y is given by:
In this problem, we have that:
Suppose the probability of a car accident taking place anywhere on a 20-mile stretch of highway is the same, which means that
Somewhere between the 5-mile and 15-mile posts of the highway:
So the correct answer is:
C. Uniform distribution
Answer:
70
Step-by-step explanation:
the formula for area of a trapezoid is (a+b)/2*h, where a and b each equal a base and h represents height. the base measurements of this figure are 9 and 11, and the height is 7 inches. in the formula, that is (9+11)/2*7. first, 9+11 is 20, divided by 2 is 10. 10*7=70, so the area is 70 in^2.
Hey there!
It’s a reflection because the two are going opposite ways. This is similar to the reflection you see in the mirror, your shirt probably looks backward and so does something you might be holding. It will go the opposite way, and that’s why when you look in the mirror it’s called a reflection- the flags are opposite so it’s a reflection.
Hope this helps!
