1/8 + 1/8 + 1/8 + 1/8 = 1/2
Answer:
40.43
Step-by-step explanation:
The mean is the sum of all the numbers divided by the number of numbers.
Sum of the numbers = 23.4 + 35.6 + 73.1 + 58.0 + 18.7 + 33.8 = 242.6
Number of numbers = 6
Hence, mean = 
This is the mean , 40.43, rounded to nearest hundredth.
Step-by-step explanation:
see the answer in the pic
u must prove that
Cotx/1+cscx=1-cscx/cotx
cuz that's the way
The first one is B and the second one is A
Answer:
20.78 cm^3 to the nearest hundredth.
Step-by-step explanation:
Volume = 1/3 * a * h where a = area of triangular base and h = the height.
The area of the triangle
= 1/2 * base * height
Its height = √(10^2-5^2)
= √75.
So its area = 1/2 * 10 * √75
= 5√75
So for the pyramid we have:
300 = 1/3 * 5√75 * h
h = 300 / (1/3 * 5√75)
= 20.78 cm^3.
