An investment counselor calls with a hot stock tip. He believes that if the economy remains strong, the investment will result in aprofit of $50,000. If the economy grows at a moderate pace, the investment will result in a profit of $10,000. However, if theeconomy goes into recession, the investment will result in a loss of $50,000. You contact an economist who believes there is a 20%probability the economy will remain strong, a 60% probability the economy will grow at a moderate pace, and a 20% probability theeconomy will slip into recession. What is the expected profit from this investment?The expected profit is $(Type an integer or a decimal.)
Answer:
6000
Explanation:
The expected profit from the investment can be calculated as the multiplication of each possible profit or loss by their respective probability.
Therefore, the expected profit is equal to:
E = 50,000(0.2) + 10,000(0.6) + (-50,000)(0.2)
E = 10,000 + 6,000 - 10,000
E = 6,000
Because there is a 20% of probability to win $50,000 (economy remain strong), there is a 60% of probability to win $10,000 (economy grows at a moderate pace), and there is a 20% of probability a loss of $50,000 (the economy goes into recession).
Therefore, the expected profit from this investment is:
6000

How many cups will stack to the top of the door frame?
Explain why...
Answer:
157 cups
Step-by-step explanation:
First, convert in to cm
83.375 in * 2.54 Cm/in = 211.77 cm
Each cup adds 1.3 cm to the (9.2 - 1.3 cm) base (Base is 7.9)
211.77 = 7.9 + 1.3 x X is the number of cups

A survey was given to people who own a sertain car. What percent of the people surveyed were completely satisfied with the car
The percent of the people surveyed were completely satisfied with the car is 55%.
How to calculate the percentage?Number of people completely satisfied = 1155
Number of people somewhat satisfied = 755
Number of people not satisfied = 190
Total number of people = 1155 + 755 + 190 = 2100
Therefore, the percent of the people surveyed were completely satisfied with the car will be:
= Number of people completely satisfied / Total number of people × 100
= 1155 / 2100 × 100
= 55%

Given the function:
f(x)=x²-3x - 4
Find the following values.
a) f(2)
f(2)=
b) f(4)
ƒ(4)=
c) f(-3)
ƒ(-3) =
The values of f(2), f(4) and f(-3) for the function, f(x) = [tex]x^{2} -3x-4[/tex], are -6, 0 and 14 respectively.
According to the question,
We have the following information:
f(x) = [tex]x^{2} -3x-4[/tex]
Now, to find the values of each function we will put the values in place of x.
We will find the value of f(2) by putting 2 in place of x.
f(2) = [tex](2)^{2} -3(2)-4[/tex]
f(2) = 4-6-4
f(2) = -2-4
f(2) = -6
(We know that the numbers with negative sign are added but the result always remains in negative.)
We will find the value of f(4) by putting 4 in place of x:
f(4) = [tex](4)^{2} -3(4)-4[/tex]
f(4) = 16-12-4
f(4) = 4-4
f(4) = 0
Now, we will find the value of f(-3) by putting -3 in place of x:
f(-3) = [tex](-3)^{2} -3(-3)-4[/tex]
f(-3) = 9+9-4
f(-3) = 18-4
f(-3) = 14
Hence, the values of f(2), f(4) and f(-3) are -6, 0 and 14 respectively.

Slope of one of the dotted lines: -1/3
Slope of the line of reflection: 3
From given figure, we can observe that the line of reflection passes through points (2, 8) and (0, 2)
We need to find the slope of the line of reflection and any dotted line.
Using the formula of slope, the slope of the line of reflection would be,
m1 = (y2 - y1)/(x2 - x1)
m1 = (2 - 8)/(0 - 2)
m1 = -6 / (-2)
m1 = 3
The dotted lines are perpendicular to the line of reflection.
Let m2 be the slope of any dotted line.
We know that the product of slopes of any perpendicular lines is -1.
so, m1 * m2 = -1
3 * m2 = -1
m2 = -1/3
So, the slope of dotted any line = - 1/3

Graph the solution to the following system of inequalities. Don’t forget to answer the point in the solution set.
Given the following System of Inequalities:
[tex]\begin{cases}7x+4y<16 \\ -5x+4y\ge12\end{cases}[/tex]You need to remember that the Slope-Intercept form of the equation of a line is:
[tex]y=mx+b[/tex]Where "m" is the slope and "b" is the y-intercept.
The steps to graph the System of Inequalities are:
1. In this case, you know that the first line is:
[tex]7x+4y=16[/tex]So you need to solve for "y" in order to write it in Slope-Intercept form:
[tex]\begin{gathered} 4y=-7x+16 \\ \\ y=\frac{-7}{4}x+\frac{16}{4} \\ \\ y=-\frac{7}{4}x+4 \end{gathered}[/tex]You can identify that the y-intercept is:
[tex]b_1=4[/tex]2. Since the value of "y" is zero when the line intersects the x-axis, you can substitute that value into the equation and solve for "x", in order to find the x-intercept:
[tex]\begin{gathered} 7x+4y=16 \\ 7x+4(0)=16 \\ 7x=16 \\ \\ x=\frac{16}{7}\approx2.286 \end{gathered}[/tex]3. Now you know that the first line passes through these points:
[tex](0,4);(2.286,0)[/tex]4. The second line is:
[tex]-5x+4y=12[/tex]So you can solve for "y" in order to write it in Slope-Intercept form:
[tex]\begin{gathered} 4y=5x+12 \\ \\ y=\frac{5}{4}x+\frac{12}{4} \\ \\ y=\frac{5}{4}x+3 \end{gathered}[/tex]Notice that the y-intercept is:
[tex]b_2=3[/tex]5. Knowing that "y" is zero when the line intersects the x-axis, you can substitute that value into the equation of the second line and solve for "x" to find the x-intercept:

The variables we need to use in the question are defined. We will call the price of a knife as [tex]k[/tex] and the price of a spoon as [tex]s[/tex].
The total price of [tex]12[/tex] spoons and [tex]16[/tex] knives is then given. Let's write knives instead of [tex]4[/tex] spoons.
[tex]12s+16k=105.64[/tex][tex]3k+16k=105.64[/tex][tex]k=5.56[/tex] per knife.===================================================
Explanation:
k = cost of one knife
s = cost of one spoon
costs are in pounds
12s = cost of 12 spoons
16k = cost of 16 knives
12s+16k = 105.64 pounds is the total cost
We can replace k with 4s because of the phrasing "a knife is 4 times the cost of a spoon". Whatever s might be, quadruple it and it leads us to the value of k.
So,
12s+16k = 105.64
12s+16(4s) = 105.64
12s+64s = 105.64
76s = 105.64
s = 105.64/76
s = 1.39 pounds is the cost of one spoon
k = 4s = 4*1.39 = 5.56 pounds is the cost of one knife
----------------------
Check:
1 spoon = 1.39 pounds
12 spoons = 12*1.39 = 16.68 pounds
1 knife = 5.56 pounds
16 knives = 16*5.56 = 88.96 pounds
12 spoons + 16 knives = 16.68+88.96 = 105.64 pounds total

There are 125 people in a sport centre.
59 people use the gym.
70 people use the swimming pool.
55 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
17 people use the gym and the track.
6 people use all three facilities.
A person is selected at random.
What is the probability that this person doesn't use any facility?
Probability that the person selected at random from the sport centre of 125 people is a fraction of 1/4 or 0.25.
Probability of an eventThe probability of an event is the fraction of the required number of outcome divided by the number of possible outcomes.
We shall determine the answer to the question as follows;
People in the sport centre = 125
People who used the 3 facilities = 6
People who accessed only gym = 59 - (6 + 11 + 19) = 26
People who accessed only track event = 55 - (6 + 11 + 24) = 14
People who accessed only swimming pool event = 70 - (6 + 19 + 24) = 21
People who accessed only gym and swimming pool events = 29 - 6 = 19
People who accessed only gym and track events = 17 - 6 = 11
People who accessed only swimming pool and track events = 30 - 6 = 24
Total number of people who accessed at least any one of the facilities = 121
The number of people who did not access any of the facility = 125 - 121 = 4, which is the number of possible outcomes for our required outcome.
Therefore, the probability that the person selected doesn't use any facility = 1/4

Find the area of ABC with verticles A(4,-3), B(9,-3) and C(10,-11)
Answer:
Step-by-step explanation:
The area of the triangle when the vertices of the triangle are given can be calculated by the following formula:
Area of triangle = 0.5 * |Ax(By - Cy) + Bx(Ay - Cy) + Cx(Ay - By)| where the vertices are A(Ax, Ay), B(Bx, By), C(Cx, Cy)
Now, we have been given the values of vertices as A(4, -3) B(9,-3) , and C(10, −11)
Therefore,
By applying the formula and substituting the given values, we get
Area = 0.5 * |4 * (-3 + 11) + 9 * (-3 + 11) + 10 * (-3 - 3)|
Area = 0.5 * |44|
Area = 22
Hence, the area of triangle ABC with the given vertices is 22 square units
