Laura is going to invest in a business. There is a 50% chance that she will make $8000, a 40% chance that she will lose $4000, and a 10% chance that she will break even (make $0). What is the expected value for Laura's investment?
Based on the various probabilities of outcomes, the expected value of the investment is $2,400
The expected value can be calculated as:
= ∑ (Probability of event happening x Payoff if event happens)
The expected value here is therefore:
= (50% x 8,000) + (40% x -4,000) + (10% x 0)
= $2,400
In conclusion, the expected value is $2,400.

Which expressions are equivalent when m = 1 and m = 4? 5 m minus 3 and 2 m 5 m 3 m 4 and m 4 2 m 2 m 7 and 3 m minus 3 m 5 m 3 and 4 m 2 2 m.
Answer:
Step-by-step explanation:
The expressions that are equivalent when m = 1 and m = 4 is;
Option B: 3m + 4 and m + 4 + 2m
We are given m = 1 and m =4;
A) 5m - 3 and 2m + 5 + m
B) 3m + 4 and m + 4 + 2m
C) 2m + 7 and 3m - 3 + m
D) 5m + 3 and 4m + 2 + 2m
For option B; 3m + 4 and m + 4 + 2m
Let's put m = 1
3(1) + 4 = 7
Also, 1 + 4 + 2(1) = 7
Similarly, let us put 4 for m to get;
3(4) + 4 = 16
Also, 4 + 4 + 2(4) = 16
In both cases, the expressions are equivalent and as such option B is the right one.

5 |2x + 6| = 25 what is x
Step-by-step explanation:
මාපාංක සුලු කිරිම.
l xl means ± x .
then |2x+6| = ±(2x+6)
for positive no;
5 (2x+6) = 25
10x + 30 = 25
10x = -5
x = -1/2
for negative no;
5(-2x - 6) = 25
-10x - 30 = 25
-10x = 55
x = - 11/2
otherthan that I observed.
5 |2x + 6| means only consider about the positive number. i think it called as amplitude.
then you have to calculate by considering only considering plus value.

Find the area of the parallelogram
Answer:
A = 99.84 cm²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 9.6 and h = 10.4 , then
A = 9.6 × 10.4 = 99.84 cm²
Step-by-step explanation:
We can see that this parallelogram is two right angles joined side by side. Normally the area of a parallelogram is Base x Height.
But let's make an exception.
For the first right angle. The area = 1/4(b+h)
¼(10.4+9.6) = 5cm²
We see that the base of the triangle is flipped and the angles correspond
so, the area would be 5cm² * 2
= 10cm²

Answer:
Y = 10/7X + 4
Y intercept = 4
Slope = 10/7
X intercept = -40/7
Step-by-step explanation:
Incase you are asked the equation of the line
The slope intercept equation is as follows -
(1)....Y = mx + b
where m - Slope
b - Y - intercept
the standard formula of slope which is commonly referred to as "the rate of change" is -
(2) .....m= Y2 - Y1 / X2 - X1
in this case you can refer to the final and initial X and Y values directly from the small points on the line.
and so(3)..... - X1 = -6 X2 = 6
- Y2 = 9 Y1 = -1
the y intercept is defined as the value we get whenever X id zero. and X has a value of zero when a line crosses the y axis.
thus, X = 0 & Y = 4 ( 0 , 4 )
now lets substitute our values(3) into the slope formula (equation 2)
m = 9 - - 1 / 6 - - 1 = 10/7
now that we found the line's slope, let's simply plug the y intercept
into the slope intercept formula (1)
Y = 10/7X + 4

Mario and Andrew's hourly charge for mowing lawns is shown.
Mario: $8.25/h
Andrew: $5.85/h
Suppose Mario and Andrew each worked for 20 hours. About how much more money did Mario earn?
about $40 explanation. in this problem you need to round and multiply so round each number 8.25 rounds to 8 and 5.85 rounds to 6 multiply each by 20 and then subtract the greater number by the less number.
A company has two warehouses that are 360 miles apart. A truck leaves Warehouse A and heads towards Warehouse B traveling at 45 miles per hour. At the same time, a truck leaves Warehouse B and heads towards Warehouse A traveling at 60 miles per hour. How long will the trucks be driving before they meet each other on the road?
between 1 and 2 hours
between 2 and 3 hours
between 3 and 4 hours
between 4 and 5 hours
Answer:
Between 3 and 4 hours
Step-by-step explanation:
Let's turn the sentence into an equation, suppose that both trucks will be traveling at a constant rate, let x be the number of hours truck A has been traveling, and let y be the number of hours truck B has been traveling. Then we can set up the equation:
[tex]45x+60y=360[/tex]
Both of these terms must add up to 360 since that will be the point where both trucks will meet. To solve this, we can use a graphing calculator:
(see picture)
Since both trucks left the warehouses at the same time, we need that: [tex]x=y[/tex]
And the point in the graph that x=y is around 3.42 and 3.44, so we can conclude that both trucks must be traveling for 3-4 hours for them to meet on the road.
I hope this helps.

What is the solution for x if
Answer: the answer is B which is x < -1
Step-by-step explanation: trust me bro and happy holidays :)
Answer:
[tex]\huge\boxed{B)\ x<-1}[/tex]
Step-by-step explanation:
Solve this inequality the same way you would solve an equation: by isolating x.
Simply subtract 6 from both sides to get -4x > 4. Then merely divide both sides by -4 to get x < -1. (Notice that when dividing by a negative number, you must flip the sign of the inequality.)
