The area of the shaded region
1 answer:
Answer:
125.66cm²
Step-by-step explanation:
so you need to find the area of the big circle and subtract it from the area of the small circle
area of a circle= π r²
small circle: substitute in what you know
a= π x 3²
a= 28.2743
big circle: substitute in what you know
a= π x 7²
a= 153.9380
now do 153.9380-28.2743=125.6637
now round this number to the nearest hundredth:
125.66cm²

Answer:
x = -8
Step-by-step explanation:
Solve for x by getting rid of the fraction.
414/(x-10) = -23
414 = -23(x-10)
414 = -23x + 230
184 = -23x
-8 = x
Using the Pythagorean Theorem, you should get 45 [9 + 36]. Then, take the square root of 45 and simplify it to 3√5.
Answer:The mean increases but the median stays the same.
Step-by-step explanation:
201 + 233 + 237 +255 +269+277+306 mean is 257 and median is 255
225 +233 + 237 +255 +269+277+306 mean is 260 and median is 255
