Answer:
a = 4
b = 4
c = -1
d = 4
e = -1
f = 4
g = -1
Step-by-step explanation:
To get the expected value equation you have to multiplicate the probability of each outcome by its reward and add them. The probability to get each color is 1/4 because the spinner has four equal-sized sections. If you win money, your reward is positive, but if you lost it, your reward is negative. Then:
expected value equation. E (V) = (1/4)*2 + (1/4)*(-1) + (1/4)*(-1) + (1/4)*(-1) = -0.25
Answer: the cost of the steel per square 0.03m
Step-by-step explanation:
The formula for determining the total surface area of a cylinder is expressed as
Total surface area = 2πr² + 2πrh
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
Total surface area = 56π
Radius = Diameter/2
radius = 12/2 = 6
height = 8 feet
Therefore,
Area = 2 × 3.14 × 6² + 2 × 3.14 × 6 × 8
Area = 226.08 + 301.44
Total surface area = 527.52
Suppose the total cost of the steel will be $17,408.16. the steel cost per square meter is
527.52/17408.16 = 0.03
<u><em>Answer: Addition property of equality, Subtraction property of equality, Multiplication property of equality, and Division property of equality.</em></u>
Step-by-step explanation:
Addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
Example: t-6=13
add 6 both sides of an equation.
t-6+6=13+6
answer: t=19
________________________________________________________
Subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
11=x+5
switch sides of equation
x+5=11
subtract by 5 both sides of an equation.
x+5-5=11=5
answer: x=6
___________________________________________________________
Multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
a*c=b*c
t/5=3
example:
5/1*t/5=3*5
then multiply on the right side.
t=3*5
answer: t=15
______________________________________________________
Division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.
a/c=b/c for c≠0
10a/10=130/10
divide by 10 both sides of an equation.
10a/10=130/10
simplify.
130/10=13
answer: a=13
