Answer:
Step-by-step explanation:
Expected value of the bet =
<h3>
P(you make the correct draw) * 40 + P(you do not make the correct draw) * (-10) = </h3>
(4/52)(4/51)(4/50) * 40 + (1 - (4/52)(4/51)(4/50)) * (-10) =
(64/132600) * 40 + (1 - 64/132600) *(-10) =
64/3315 + (132536/132600) * (-10) =
64/3315 - (132536/13260) =
64/3315 - 33134/3315 =
-33070/3315 =
-9.97586726998 =
-$9.98, rounded to the nearest cent
(i.e., the expected value of the bet is a loss of $9.98)
What is this supposed to mean? Is it a chart??
3/5x+22=28 (Simplify, get all the whole numbers on one side)
-22 -22
5(3/5x)=(6)5 (Get rid of the fraction by multiplying everything by 5)
3x=30 (Get the variable by itself, divide by 3)
x=10
Answer:
It is required to draw a number line showing equivalent fractions.
'Equivalent fractions' are the fractions having same value even though the digits involved are different'.
For example: Consider, 
and 
.
Now, we have,
= 0.5
= 0.5
Thus, the both fractions have the same value, even though we are dividing different digits.
Thus, and are called equivalent fractions.
So, we plot them on the number line, resulting in the following figure with point P = 0.5.
Answer:
(x,y) = (1,2)
Step-by-step explanation:
I used a graphing calculator and put both equations in to find the intersection.
