Answer:
x = 4
Step-by-step explanation:
we know that 72 and (2x + 10) add up to 90

(2x + 10) = 18
2x = 8
x = 4

The formula for a cylinder is V = (pi) (r^2) (h) so 12*12 is 144. 144*pi*17 is 2448 pi units cubed.
Answer:
Yes, the test was conducted with a risk of a type I error.
Step-by-step explanation:
If we reject the null hypothesis, does this mean that we have proved it to be false beyond all doubt? Explain your answer.
Yes, for a null hypothesis to be rejected, it has being proven beyond all doubt that the null hypothesis will not work. the normal distribution has being used for the probability calculation.
if the null hypothesis is rejected and the alternative hypothesis is accepted, a type I error as occur.
In general terms:
‘a hypothesis has been rejected when it should have been accepted’. When this occurs, it is called a type I error.
<span><u><em>The correct answer is: </em></u>
535.
<u><em>Explanation</em></u><span><u><em>: </em></u>
4 hundreds = 4*100=400.
13 tens = 13*10 = 130.
5 ones = 5*1=5.
Together, this gives us 400+130+5=535.</span></span>
