Answer:
9/8
Step-by-step explanation:
The average selling price is $0.60 per unit, the average variable cost is $0.36 per unit, and the total fixed costs are $1,500. If operating profits of $900 are desired, a sales volume of 2,500 units is necessary. True False
The statement is False.
Given that the SP is $0.60 per unit and the CP is $0.36 per unit.
So, profit per unit = $(0.60-0.36)
= $ 0.24
So, now we have to check whether 2500 units sales is required if we want a profit of $900.
To check we have to multiply the profit per unit with the sales,
⇒ 0.24 × 2500
⇒ $ 600
We can see clearly that we get a profit of $600 if we sale 2500 units. So, to make a profit of $900 we have to sale = [tex]\frac{900}{0.24}[/tex]
= 3750 units

What is the slope of y = log(x) when x=20 ?
The formula for the slope is _________ for h close to 0 (but not equal )
The best estimate for the slope is____

The formula for slope according to first principle is :
[tex] \qquad \sf \dashrightarrow \: \[ \displaystyle\lim_{x\to0} \: \: \sf \frac{f(x + h) - f(x)}{h} \][/tex]
[tex] \qquad \sf \dashrightarrow \: \[ \displaystyle\lim_{x\to0} \: \: \sf \frac{ log(x + h) - log(x)}{h} \][/tex]
[tex] \qquad \sf \dashrightarrow \: \[ \displaystyle\lim_{x\to0} \: \: \sf \frac{ log( \frac{x + h}{x} ) }{h} \][/tex]
[tex] \qquad \sf \dashrightarrow \: \[ \displaystyle\lim_{x\to0} \: \: \sf \frac{ log( \frac{ h}{x} + 1 ) }{h} \][/tex]
[tex] \qquad \sf \dashrightarrow \: \[ \displaystyle\lim_{x\to0} \: \: \sf \frac{ log( \frac{ h}{x} + 1 ) }{ \frac{h}{x} \times x} \][/tex]
[tex] \qquad \sf \dashrightarrow \: \[ \displaystyle\lim_{x\to0} \: \: \sf \frac{1}{x} \bigg(\frac{ log_{e} ( \frac{ h}{x} + 1 ) }{ \frac{h}{x} \times log_{e}(10) } \] \bigg)[/tex]

HEY YOU!! PLEASE I NEED HELPPP
find angle BAC and angle FAB
Answer:
m∠BAC = 105°
m∠FAB = 75°
Step-by-step explanation:
By using the property of an exterior angle of a triangle,
Measure of an exterior angle is equal to the sum of opposite two angles of a triangle.
From the triangle given in the picture,
m∠ABC + m∠BCA + m∠CAB = 180°
(13x - 3)° = (3x + 2)° + 55°
13x - 3 = 3x + 57
13x - 3x = 57 + 3
10x = 60
x = 6
m∠FAB = (13x - 3)° = 75°
m∠ABC = (3x + 2)° = 20°
Since, ∠BAC and ∠FAB are the linear pair of angles,
m∠BAC + m∠FAB = 180°
m∠BAC + 75° = 180°
m∠BAC = 180° - 75° = 105°

A 99% confidence interval for the population mean yields the following results: [−3.79, 5.86]. At the 1% significance level, what decision should be made regarding the following hypothesis test with LaTeX: H_0H 0: LaTeX: \mu=0μ = 0 versus LaTeX: H_1H 1: LaTeX: \mu\ne0μ ≠ 0?
Answer:
Decision rule: Do not reject [tex]H_o[/tex]; we cannot conclude that the mean differs from zero
Step-by-step explanation:
From the given information:
The null hypothesis and alternative hypothesis is given as:
[tex]H_o: \mu = 0 \\ \\ H_1 : \mu \ne 0[/tex]
And the 99% confidence interval for the population mean [tex]\mu[/tex] is: [−3.79, 5.86]
The significance level ∝ = 1 - 0.99 = 0.01
We will notice that the 99% confidence interval for the population mean [tex]\mu[/tex] contains the null hypothesis mean value which is equal to zero.
Thus, we do not reject the null hypothesis at the significance level ∝ = 0.01
∴
Decision rule: Do not reject [tex]H_o[/tex]; we cannot conclude that the mean differs from zero

Paloma has a flower stand at a farmer’s market. On Tuesday, she sold 8 marigold flats and 10 daisy flats.
An hour before closing, she sold 5 bunches of roses at half price and 2 bunches of lilies for 13 of the price.
Evaluate a numerical expression to find out how much money Paloma made. Enter your answer in the box.
The total money Paloma made = $117.25
In this question,
The price of Marigold(M) is $5.75.
The price of Daisy(D) is $6.25.
The price of Roses(R) is $2.50.
The price of Lilies(L) is $3.75
She sold 8 marigold flats and 10 daisy flats. An hour before closing, she sold 5 bunches of roses at half price and 2 bunches of lilies for 1/3 of the price.
Let s be the total money Paloma made
so we get an expression,
S = 8M + 10D + 5(R/2) + 2(L/3)
Now substitute the respective value
S = 8(5.75) + 10(6.25) + 5(2.5/2) + 2(3.75/3)
S = 46 + 62.5 + 6.25 + 2.5
S = $117.25
Therefore, the total money Paloma made = $117.25

0, 6, 12, ...This is an AP with the first term of a₁ = 0 and common difference of d = 6.
Explicit formula for an AP is:
aₙ = a₁ + (n - 1)dSubstitute the first term a₁ and common difference d into equation:
aₙ = 0 + (n - 1)*6aₙ = 6(n - 1)The 24th term is:

A customer paid a total of $6.00 for 68 copies at a print shop. Some of the copies were
black-and-white copies, and the rest were color copies.
• Each black-and-white copy cost $0.08.
• Each color copy cost $0.15.
Which system of equations can be used to find b, the number of black-and-white copies, and
c, the number of color copies that the customer paid for at the print shop?
The system of equations for find b, the number of black-and-white copies, and c, the number of color copies that the customer paid for at the print shop is,
⇒ b + c = 68
⇒ 0.08b + 0.15c = 6
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
Total amount paid = $6.00
Total copies = 68
Cost of black-and-white copy = $0.08
Cost of color copy = $0.15
Now, Let number of black-and-white copies = b
And, Number of color copies = c
Hence, The equation become;
b + c = 68
0.08b + 0.15c = 6
Therefore, The system of equations for find b, the number of black-and-white copies, and c, the number of color copies that the customer paid for at the print shop is,
⇒ b + c = 68
⇒ 0.08b + 0.15c = $6

You can tell if a graph represents a proportional relationship by identifying the y-intercept, or the point of the line that crosses the y-axis.
If the y-intercept is 0, then the relationship is proportional. This is called a direct relationship.
If the y-intercept is anything other than 0, then the relationship is not proportional. This is called an indirect relationship.
