Answer:
10
Step-by-step explanation:
10x2+10
=10(2x+1)
This becomes........
sqrt(72/50) x sqrt(x^16/x^36)= sqrt(36/25) x sqrt(x^-20)= 6/5 x x^-10= 6/(5x^10)
If x=first even number in sequence, then the next even number would be that number plus 2, plus 4, and so on.
x + (x+2) + (x+4) + (x+6) + (x+8) = 100
5x+20=100
5x=80
x=16
Answer:
Lowering the level of significance, α increases the probability of making a Type II error, β.
Step-by-step explanation:
Lowering the level of significance, α increases the probability of making a Type II error, β.
This is because the region of acceptance becomes bigger, and it makes it less likely for one to reject a null hypothesis, when it is false, the type II error.
Answer:
Step-by-step explanation:
Hello, let's say that the price was P, a real number.
After 20% discount it become P - 20% * P = P* (1-20%) = P * (1 - 0.2)
= P * 0.8
And then we take 15% for the VAT, the new price become P * 0.8 * ( 1 + 15%)
= P * 0.8 * 1.15
And this is equal to 22080, so
P * 0.8 * 1.15 = 22080
and the amount of the VAT is P *0.8 * 0.15
Hope this helps.
Thank you.
