n = (180-133) + (180-142)
An ext. angle is equal to the sum of two opposite int. angles
n = 47 + 38
Add:
<u>n = 85</u>
<u>Option D</u>
Answer: 284.7
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(1/2)*(4/3)*3.14* (4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)h
=(1/3)*3.14**9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69
=284.7
Answer:
Pretty sure a loss of -27.08%, check the formula for loss percent
Step-by-step explanation:
Assuming this means 120 for 20 oranges.
so for 200, every 20 was bought for 120.
There are 10 20s in 200 so that's 10 score, which means 120*10 = 1200
So 1200 was spent.
25 were rotten which means they now have 175
selling for 5 each means 5*175 = 875 was the profit.
Since they spent 1200 and made 875 there was a loss.
Then I think percent loss/ gain is (revenue - cost)/cost where revenue is what was made and cost is what was spent. so this makes (875-1200)/1200 = -.2708 = -27.08%
Kinda rusty on this so double check what loss percent is.
Answer:
If the lifetime of batteries in the packet is 40.83 hours or more then, it exceeds for 5% of all packages.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 15
Standard Deviation, σ = 1
Sample size = 4
Total lifetime of 4 batteries = 40 hours
We are given that the distribution of lifetime is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling:
We have to find the value of x such that the probability is 0.05
P(X > x) = 0.05
Calculation the value from standard normal z table, we have,
Hence, if the lifetime of batteries in the packet is 40.83 hours or more then, it exceeds for 5% of all packages.
