If the fixed cost is GHC500, the total profit or loss of producing 100 units is GHC 0.
What is the profit when MC = MR?When the marginal cost (MC) equals the marginal revenue (MR), the company breaks even, and from that point, profit maximization starts.
When MR is more than MC, the tendency is for the firm to produce more and earn more profit, and when MR is less than MC, the firm produces fewer as it incurs losses.
The profit maximization level occurs where the MR and the MC are equal.
Data and Calculations:Total revenue = fixed cost + variable cost (MR x Units)
Total revenue = 500 + (100 x 250)
Total revenue = 500 + 25,000
Total revenue = GHC 25,500
Total profit or loss at 100 units = GHC0 (GHC25,500 - GHC25,500)

The acute angle the ladder makes with the ground is 69.3 degrees.
How to find the acute angles formed from the right triangle ?The ladder is 5.1 m and it is leaning against a wall.
The wall is perpendicular to the ground.
This means the ground forms 90 degrees with the wall.
This situation forms a right angle triangle.
Therefore, the acute angle the ladder forms with the ground can be found as follows:
Using trigonometric ratios,
cos ∅ = adjacent / hypotenuse
where
∅ = acute angle
Therefore,
adjacent side = 1.8 m
hypotenuse side = 5.1 m
Hence,
cos ∅ = 1.8 / 5.1
∅ = cos⁻¹ 0.35294117647

What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value.

the weight of an organ in adult male has a bell shaped distribution with a mean of 300 grams and a standard deviation of 25 grams. Use the empirical rule to determine the following:
a.) About 95% of organs will be between what weights?
b.) What percentage of organs weighs between 225 grams and 375 grams?
c.) What percentage of organs weighs less than 225 grams or more than 275 grams?
d.) what percentage of organs weighs between 275 grams and 275 grams?
Using the Empirical Rule, it is found that:
a) About 95% of the organs will be between 250 and 350 grams.
b) 99.7% of organs weighs between 225 grams and 375 grams.
c) 84.15% of organs weighs less than 225 grams or more than 275 grams.
d) 0% of organs weight exactly 275 grams.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.95% of the weights are within 2 standard deviations of the mean, hence:
300 - 2 x 25 = 250 grams.300 + 2 x 25 = 350 grams.About 95% of the organs will be between 250 and 350 grams.
For item b, the amounts are within 3 standard deviations of the mean, hence:
99.7% of organs weighs between 225 grams and 375 grams.
For item c, considering the symmetry of the normal distribution, we have that:
0.5 x 0.003 = 0.15% weigh less than 225 grams.0.5 x 68% + 50% = 84% weight more than 275 grams.Hence:
84.15% of organs weighs less than 225 grams or more than 275 grams.
For item d, considering that the normal distribution is continuous, the percentage of an exact value is 0, hence:
0% of organs weight exactly 275 grams.

For each function, find the vertex, the axis of symmetry, the y-intercept, the x- intercepts (if any), whether the parabola opens upward or downward, the intervals on which the function is increasing or decreasing, the maximum or minimum value, and the range. Then sketch the graph. y = -2(x + 3)² + 8
Given parabola [tex]y=-2(x+3)^{2} +8[/tex] have vertex (-3,8)
axis of symmetry :x=-3
x intercepts (-1,0),(5,0)
y intercepts (0,-10)
Maximum value (-3,8)
Range is y[tex]\leq 8[/tex] or (-∞,8]
Parabola is increasing in (-∞,-3) and decreasing in (-3,∞)
How to identify parabola type from vertex form and its attributes?
The parabola equation y=ax²+bx+c
The parabola equation in its vertex form is
y = a(x - h)² + k, where
a is same as the a coefficient in the standard form;
(h, k) is coordinates of the vertex of parabola
h and k can be calculated as
h = - b/(2a)
k = c - b²/(4a)
If a is negative the parabola opens downward and if a is positive the the parabola opens upward
Axis of symmetry : x= h
For a parabola y=ax²+bx+c if a<0 then the range is y [tex]\leq k[/tex] and if a>0 then range is y[tex]\geq k[/tex]
For Maximum and minimum value , if a<0 then vertex is the maximum value and if a>0 then vertex is the minimum value.
For given equation [tex]y=-2(x+3)^{2} +8[/tex]
As this equation is in vertex form
h=-3, a=-2, k=8
Therefore, vertex = (-3,8)
For x intercept put y=0
Then [tex]y=-2(x+3)^{2} +8\\y\\=-2x^{2} -12x-10\\y=0\\\\x=-1,-5\\put x=0 \\y= -10[/tex]x intercepts (-1,0),(5,0)
y intercepts (0,-10)
Axis of symmetry : x= -3
[tex]y=-2(x+3)^{2} +8\\y=-2x^{2} -12x-10[/tex]
As a is negative therefore range is y[tex]\leq 8[/tex] or (-∞,8]
As a is negative therefore vertex (-3,8) is the maximum value
f'(x)= -4x-12
f'(x)=0 gives x= -3

Cyndee wants to invest $50,000. Her financial planner advises her to invest in three types of accounts: one paying 3%, one
paying 5%, and one paying 6% simple interest per year. Cyndee wants to put twice as much in the lowest-yielding, least-risky
account as in the highest-yielding account. How much should she invest in each account to achieve a total annual return of
$2120?
Answer:
$25,333.33 at 3%$12000 at 5%$12,666.67 at 6%Step-by-step explanation:
Cyndee invests $50,000 in accounts earning 3%, 5%, and 6% annually, for a total annual return of $2120. She puts twice as much in the first account as in the third. You want to know the amount invested in each account.
SetupLet x represent the amount invested in the third account. Then 2x is the amount invested in the first account, and (50000 -3x) is the amount invested in the second account. The total return is ...
0.03(2x) +0.05(50000 -3x) +0.06(x) = 2120
SolutionSimplifying the equation gives ...
-0.03x +2500 = 2120
380 = 0.03x . . . . . . . . . . add 0.03x-2120
12,666 2/3 = x . . . . . . . divide by 0.03
2x = 25,333 1/3
50000 -3x = 12,000
Cyndee should invest 25,333.33 at 3%, $12,000 at 5%, and $12,666.67 at 6%.

If Cindy shoots a ball at a basket 40 times
and scores 15 times, what is the
experimental probability of Cindy scoring?
Experimental probability of Cindy scoring=0.375
Probability:
Probability is always a number between 0 and 1, where 0 means an event is impossible and 1 means an event is certain.
The probabilities in a probability model must sum to 1.
When the outcomes of an experiment are all equally likely, we can find the probability of an event by dividing the number of outcomes in the event by the total number of outcomes in the sample space for the experiment.
To find the probability of the union of two events, we add the probabilities of the two events and subtract the probability that both events occur simultaneously.
To find the probability of the union of two mutually exclusive events, we add the probabilities of each of the events.
The probability of the complement of an event is the difference between 1 and the probability that the event occurs.
In some probability problems, we need to use permutations and combinations to find the number of elements in events and sample spaces.
Formula :
probability of an event with equally likely outcomes : [tex]\frac{n( experimental-event )}{n(total no. of event )}[/tex]
Given :
Total no. of event =Cindy shoots a ball at a basket 40 times
