Answer:
$3.50
Step-by-step explanation:
Given:
$10 for a 6, $7 for a 5, $4 for a 4, and no payoff otherwise
P(6) = 1/6 ; p(5) = 1/6 ; p(4) = 1/6 ; p(1,2or3) = 3/6 = 1/2
P(x) ____ 1/6 _____ 1/6 _____1/6 _____1/2
x______ 10 _______ 7 _____ 4 _______ 0
Expectwd value ; E(x)
Σx*p(x) = (1/6 * 10) + (1/6 * 7) + (1/6 * 4) + (1/2 * 0)
E(x) = 3.50
Answer:
Step-by-step explanation:
A recipe for four batches of bread uses 5 cups of flour.
Firstly, we want to determine the number of cups of flour needed to produce one batch of bread. This means we want to determine the unit rate of producing batches of bread. It becomes
If four batches of bread uses 5 cups of flour,
Then 1 batch of bread will use x cups of flour
4x = 5
x = 5/4 = 1.25
1 batch of bread will require 1.25 cups of flour
Secondly, we want do determine how many batches of bread that can be made using 1 cup of flour. It becomes
If four batches of bread uses 5 cups of flour, then
y batches of bread will need 1 cup of flour
5y = 4
y = 4/5 = 0.8
1 cup of flour will produce 0.8 batch of bread
Answer:
See attached picture and description below.
Step-by-step explanation:
Graph each equation as you would graph any linear function. Plot the y-intercept for the first equation at (0,5) then move down 0.5 units and to the right 1 unit. This is the right boundary and should be plotted with an open circle. (red graph.
The second equation should be graphed starting at the y-intercept (0,-2.5) then proceeding down 0.5 units and over 1 unit to the right. (blue graph)
See graph below for complete graph.
Set up the equation...
1/8(23 + 17)=
1/8 (40) =
1/8 × 40/1 =
40/8 = 5
