So the 1 case of tile is $21
$21 x 5 = $105
Answer:
we know that
[the lateral area of a right circular cone]=pi*r*l
where
r--------------> the radius of the circle part of the cone
l--------------> the side (slant height) of the cone
r=6 ft
h=8 ft
Step 1
find the slant height of the cone
which is determined by using Pythagoras, since the cross section is a right triangle.
l² = h²+ r²------------> l²=8²+6²-------> l²=64+36---------> l=10 ft
Step 2
find the lateral area
[the lateral area of a right circular cone]=pi*r*l--------> pi*6*10----> 188.4 ft²
the answer is 188.4 ft²

Step-by-step explanation:
Answer:
The middle 99.7% of Twinkies weigh between approximately 1.2 and 1.8 ounces.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 1.5
Standard deviation = 0.1
middle 99.7%
Within 3 standard deviations of the mean, so
1.5 - 3*0.1 = 1.2
1.5 + 3*0.1 = 1.8
So the answer is:
The middle 99.7% of Twinkies weigh between approximately 1.2 and 1.8 ounces.
