<u>Given</u>:
Given that the radius of the cone is 2 inches.
The height of the cone is 4 inches.
We need to determine the volume of the cone.
<u>Volume of the cone:</u>
The volume of the cone can be determined using the formula,
where r is the radius of the cone and h is the height of the cone.
Substituting r = 2 and h = 4 in the above formula, we get;
Thus, the volume of the cone is 16.75 cubic inches.
Answer:
x²+5x-10=0
x²+(2-7)x-10=0
x²+2x-7x-10=0
x(x+2)-7(x+2)=0
=x+2=0
=x=-2
=x-7=0
=x=7
hope may be right.....
Step-by-step explanation:
So you add 13+5=18
Then you do 144/18=8
8x13=104 8x5=40
104+40=144✅
Answer= 104 : 40
Answer:
we say for μ = 50.00 mm we be 95% confident that machine calibrated properly with ( 49.926757 , 50.033243 )
Step-by-step explanation:
Given data
n=29
mean of x = 49.98 mm
S = 0.14 mm
μ = 50.00 mm
Cl = 95%
to find out
Can we be 95% confident that machine calibrated properly
solution
we know from t table
t at 95% and n -1 = 29-1 = 28 is 2.048
so now
Now for 95% CI for mean is
(x - 2.048 × S/√n , x + 2.048 × S/√n )
(49.98 - 2.048 × 0.14/√29 , 49.98 + 2.048 × 0.14/√29 )
( 49.926757 , 50.033243 )
hence we say for μ = 50.00 mm we be 95% confident that machine calibrated properly with ( 49.926757 , 50.033243 )
