Answer:
Juan
Step-by-step explanation:
3x8=24, but in this case, you are doing exponents. So you have to do this equation
3x3x3x3x3x3x3x3=6561
Sure! So you need to make an addition problem, for example, 200+25; that equals 225, right? Now you need to subtract from 225. For example, 225-10= 215. Hope I helped!
Answer:
The indicated confidence interval for the difference between the two population means is (-1.5159, 7.5159)
Step-by-step explanation:
Let the drying times of type A be the first population and the drying times of type B be the second population. Then
We have small sample sizes 
and 
, besides 
, 
, 
and 
. Therefore, the pooled
estimate is given by
The 99% confidence interval for the true mean difference between the mean drying time of type A and the mean drying time of type B is given by
, i.e.,
where 
is the 0.5th quantile of the t distribution with (11+9-2) = 18 degrees of freedom. So
, i.e.,
the indicated confidence interval for the difference between the two population means is (-1.5159, 7.5159)
Answer:we know that
area of triangle=b*h/2
b=(x-2) m
Area=(x²-4) m²
h=?
(x²-4)=(x+2)*h/2
but remember that
(x²-4)=(x+2)*(x-2)
so
subsititute
(x+2)*(x-2)=(x+2)*h/2
(x-2)=h/2
h=2*(x-2)
the answer is
the height of a triangle is 2*(x-2)
