Answer:
Required probability is 0.9748
Step-by-step explanation:
given data
mean 
= 117.7-cm
standard deviation 
= 2.2-cm
sample size n = 29
solution
we consider here random variable which represents here length of rod= x
so get here first z that is express as
put here value with x value 118.5-cm
Z = 1.9582
p value is 0.9748
so required probability is 0.9748
Answer:
5692.421
Step-by-step explanation:
3.421 + 5689 = 5692.421
Answer:
84cm^2
Step-by-step explanation:
The pyramid's SA is the square at the bottom plus the triangles on the side.
The square is 6x6=36.
Per triangle, it's BxH/2. B=6. H=4. Therefore, per triangle has a SA of 12 cm^2.
There are 4 triangles. 48 cm^2 in total for the triangles
36cm^2+48cm^2=84cm^2
Let the yellow corn be x
And other variety be y
Question says that she brought a dozen (as total)
So,
x +y = 12
If cost of yellow corn was 40 cent and cost of other varieties were 50 cents then,
(After changing those cents into dollar)
0.40x+ 0.50y = 5.70
Because she paid a total of 5 dollar 70 cents for yellow and other variety.
So, option "a" is correct.
