Answer:
(a) 0.932
(b) 0.0653
(c) 0.032
(d) 0.316
(e) 0.251
Step-by-step explanation:
From the table with mean parameter μ = 5, we can compute the following cumulative and density probability
(a) 
(cumulative)
(b) P(X = 8) = 0.0653 (density)
(c) 
(cumulative)
(d) 
(cumulative)
(e) 
The quadratic formula is -b plus minus the square root of b^2-4ac all over 2a.
Here, a=1, b=13, and c=30.
The only option that fills in the values correctly is D
First we need to calculate the volume which is Base*depth or length*width*depth
first we have to change all the units so they are the same, 3 inches in this case will equal 1/4feet
multiply all the numbers together
35ft*12ft*1/4foot= 105 cubic feet
however the problem says the cost per cubic *yards*
so take the 105 cubic feet and divide by 3 (3 feet to a yard)
105/3 = 35 cubic yards
the cost of 35 cubic yards of concrete =
35*125= $4375
Since we are asked for tge graph that represent the total cost for the x numbers of lesson, it will be helpful to illustrate it first this way
for each lesson it will cost $30 dollars
1 lesson $30
2 lessons $60
3 lessons $90
4 lessons $120
5 lessons $150
So from this set of numbers , it is apparent that the grqph in letter c represents the total costs for x numbers of lessonsseethati
