The lateral area would be 298.7 cm².
The lateral area is the area of all of the lateral faces of the pyramid. There are 8 triangles making up the lateral faces. Each has a base of 6.6. The formula for the area of a triangle is
A=1/2bh,
so we still need the height of the triangle.
The height of each lateral triangle is the slant height of the pyramid. The slant height of the pyramid forms a right triangle with the height of the pyramid and the "radius" as it were of the pyramid. Thus we use the Pythagorean theorem:
8²+8²=h²
64+64=h²
128=h²
√128=√(h²)
8√2 = h
Substituting this into our area formula we have:
A=1/2(6.6)(8√2)
We will go ahead and multiply this by 8, since there are 8 lateral faces:
LA=8(1/2)(6.6)(8√2)
LA = 298.7
Answer:
the probability of having sickle cell anemia given that you are African-American is P( B|A) =0.288
Step-by-step explanation:
Using Bayes's theorem
P( B|A) = P( A∩B)/P(A)
where P( B|A) = probability of the event B knowing that A happened , P( A∩B) = probability that A and B happen (joint probability of A and B) , P(A) = probability of event A
if B= probability of having sickle cell anemia and A= probability of being African-American
then
P( A∩B) = 0.13
P(A) = 0.45
then
P( B|A) = P( A∩B)/P(A) = 0.13/0.45 = 0.288
P( B|A) =0.288

Answer:
6.7
Step-by-step explanation:
6.7 because 3.4 is way to small 7.9 would be close but not the right length and 8.5 is way too long to be on the bottom.
Hope this help stay home stay safe.
Have a great day :) :) :) :)
Answer:
This is true!
Step-by-step explanation:
It is natural because it is a positive integer greater than 0, it's whole because its not negative and it is an integer.
