I assumed you are referring to the Net (take away by the seller after removing their commissions).
Answer:
Selling price
Step-by-step explanation:
To determine what amount goes to the seller, we multiply the selling price of a commodity in question by the percentage (commissions) to the seller.
Note that the resulting amount is the value of the commission paid to the seller, the actual net is gotten by substracting the selling price from the commission paid.

Step-by-step explanation:
Seven baseballs are randomly selected from the production line to see if their stitching is straight. Over time, the company has found that 89.4% of all their baseballs have straight stitching. If exactly five of the seven have straight stitching, should the company stop the production line
Answer:
The probability that exactly five of the seven have straight stitching is very low only 13.47%, this means that the company should stop the production line.
Step-by-step explanation:
We are given that Seven baseballs are randomly selected from the production line to see if their stitching is straight. Over time, the company has found that 89.4% of all their baseballs have straight stitching.
Let X = Number of baseballs having straight stitching
The above situation can be represented through the binomial distribution;
[tex]P(X = r) = \binom{n}{r} \times p^{r}\times (1-p)^{n-r};x=0,1,2,3,.......[/tex]
where, n = number of samples (trials) taken = 7 baseballs
r = number of success = exactly 5
p = probbaility of success which in our question is the probability
that baseballs have straight stitching, i.e.; p = 89.4%
So, X ~ Binom(n = 7, p = 0.894)
Now, the probability that exactly five of the seven have straight stitching is given by = P(X = 5)
P(X = 5) = [tex]\binom{7}{5} \times 0.894^{5}\times (1-0.894)^{7-5}[/tex]
= [tex]21 \times 0.894^{5}\times 0.106^{2}[/tex]
= 0.1347 or 13.47%
Since the probability that exactly five of the seven have straight stitching is very low only 13.47%, this means that company should stop the production line.

Answer:
[tex]\angle B_{1} \approx 31.668^{\circ}[/tex], [tex]\angle B_{2} \approx 148.332^{\circ}[/tex]
[tex]\angle C_{1} \approx 127.332^{\circ}[/tex], [tex]\angle C_{2} \approx 10.668^{\circ}[/tex]
[tex]c_{1} \approx 157.532[/tex], [tex]c_{2}\approx 36.676[/tex]
Step-by-step explanation:
The Law of Sines states that:
[tex]\frac{a}{\sin A} = \frac{b}{\sin B}=\frac{c}{\sin C}[/tex]
Where:
[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Side lengths, dimensionless.
[tex]A[/tex], [tex]B[/tex], [tex]C[/tex] - Angles opposite to respective sides, dimensionless.
Given that [tex]a = 71[/tex], [tex]b = 104[/tex], [tex]\angle A = 21^{\circ}[/tex], the sine of angle B is:
[tex]\sin B = \frac{b}{a}\cdot \sin A[/tex]
[tex]\sin B = \frac{104}{71}\cdot \sin 21^{\circ}[/tex]
[tex]\sin B = 0.525[/tex]
Sine is positive between 0º and 180º, so there are two possible solutions:
[tex]\angle B_{1} \approx 31.668^{\circ}[/tex]
[tex]\angle B_{2} \approx 148.332^{\circ}[/tex]
The remaining angle is obtained from the principle that sum of internal triangles equals to 180 degrees: ([tex]\angle A = 21^{\circ}[/tex], [tex]\angle B_{1} \approx 31.668^{\circ}[/tex], [tex]\angle B_{2} \approx 148.332^{\circ}[/tex])
[tex]\angle C_{1} = 180^{\circ}-\angle A - \angle B_{1}[/tex]
[tex]\angle C_{1} = 180^{\circ}-21^{\circ}-31.668^{\circ}[/tex]
[tex]\angle C_{1} \approx 127.332^{\circ}[/tex]
[tex]\angle C_{2} = 180^{\circ}-\angle A - \angle B_{2}[/tex]
[tex]\angle C_{2} = 180^{\circ}-21^{\circ}-148.332^{\circ}[/tex]
[tex]\angle C_{2} \approx 10.668^{\circ}[/tex]
Lastly, the remaining side of the triangle is found by means of the Law of Sine: ([tex]a = 71[/tex], [tex]\angle A = 21^{\circ}[/tex], [tex]\angle C_{1} \approx 127.332^{\circ}[/tex], [tex]\angle C_{2} \approx 10.668^{\circ}[/tex])
[tex]c_{1} = a\cdot \left(\frac{\sin C_{1}}{\sin A} \right)[/tex]
[tex]c_{1} = 71\cdot \left(\frac{\sin 127.332^{\circ}}{\sin 21^{\circ}} \right)[/tex]
[tex]c_{1} \approx 157.532[/tex]
[tex]c_{2} = a\cdot \left(\frac{\sin C_{2}}{\sin A} \right)[/tex]
[tex]c_{2}= 71\cdot \left(\frac{\sin 10.668^{\circ}}{\sin 21^{\circ}} \right)[/tex]
[tex]c_{2}\approx 36.676[/tex]
The answer are presented below:
[tex]\angle B_{1} \approx 31.668^{\circ}[/tex], [tex]\angle B_{2} \approx 148.332^{\circ}[/tex]
[tex]\angle C_{1} \approx 127.332^{\circ}[/tex], [tex]\angle C_{2} \approx 10.668^{\circ}[/tex]
[tex]c_{1} \approx 157.532[/tex], [tex]c_{2}\approx 36.676[/tex]

Rewrite the given amount of profits in the number form as follows:
MegaMart: 1.7*10⁹ = 1.7*1,000,000,000 = 1,700,000,000
Vision Cell: 9*10⁸ = 9*100,000,000 = 900,000,000
Ace Motors: 6.2*10⁹ = 6.2*1,000,000,000 = 6,200,000,000
Urban: 4*10⁵ = 4*100,000 = 400,000
Punchbuggies: [tex] 2.7*10^{10} [/tex] = 2.7*10,000,000,000 = 27,000,000,000
Now we can easily order the profits of the companies from greatest to least amount:
Punchbuggies: 27,000,000,000
Ace Motors: 6,200,000,000
MegaMart: 1,700,000,000
Vision Cell: 900,000,000

Step-by-step explanation:
A farmer is setting up separate pens for livestock by fencing off a rectangular area and running fence to create three parallel pens. If the farmer has to enclose a total area of 9,800 square meters, what is the shortest length of fence needed
Answer:
L(min) = 560 m
Step-by-step explanation:
Dimensions of rectangular area are: "x" and "y"
Then x*y = 9800 m²
If this area have to be divided into three parallel pens total length of fencing material would be:
L = 2*x + 4*y
And L as a function of x is
x*y = 9800 ⇒ y = 9800/x
L(x) = 2*x + 4 * 9800/x ⇒ L(x) = 2*x + 39200/x
Taking derivatives on both sides of the equation we get
L´(x) = 2 - 39200/x²
L´(x) = 0 ⇒ 2 - 39200/x² = 0
2*x² - 39200 = 0
x² = 39200 / 2 ⇒ x² = 19600
x = 140 m
And y = 39200/ 140
y = 70 m
Then minimum length of fence is:
L(min) = 2*140 + 4*70
L(min) = 280 + 280
L(min) = 560 m
Checking in the second derivative:
L´´(x) = 2*39200/x³ > 0 then we get a minimum of the function L at the point x = 140
Convert the inequalities into equations, and then use the substitution method to find four possible vertices in the form (x, y, z).
Answer:
For 2x + 5y < 100, x + y < 30. Vertices : (50,0) , (0,20) , (35,0) , (0,35) , (25,0)
Step-by-step explanation:
Considering inequality equations
i) 2x + 5y < 100 ;
ii) x + y < 35
Concerting them to equality conditions
i) 2x + 5y =100.
Intercepts : If y = 0, x = 50. So, (50,0). If x = 0, y = 20. So, (0,20)
ii) x + y = 35. Intercepts :
Intercepts : If y = 0, x = 35. So, (35,0). If x = 0, y = 35 So, (0,35)
Solving them as per equality (with substitution)From ii), x = 35 - y . Putting the value in i)
2 (35 - y) + 5y = 100 → 70 - 2y + 5y = 100 → 70 + 3y = 100
3y = 100 - 70 → 3y = 30 → y = 30 / 3 = 10
Putting y = 10 in ii) : x = 35 - 10 = 25
As per the 'less than' inequalities : the inner 'towards origin' area from both lines is in common shaded area.Henceworth, vertices are : (50,0) , (0,20) , (35,0) , (0,35) & intersection (25,0)

I(t) models the daily solar irradiance, measured in kWh/m2-day on a farm, t days after the summer solstice. Here, t is entered in radians. I(t) = 1.5cos(2π/365*t)+4.3 What is the second time after the summer solstice that the solar irradiance is 5.2kWh/m2-day Round your final answer to the nearest whole day.
Answer:
311 days
Step-by-step explanation:
I(t) = 1.5 cos(2π/365 t) + 4.3
5.2 = 1.5 cos(2π/365 t) + 4.3
0.9 = 1.5 cos(2π/365 t)
0.6 = cos(2π/365 t)
2π/365 t = cos⁻¹(0.6)
2π/365 t = 0.927, 5.356
t ≈ 54, 311
Answer:
First time is 54
Second time is 311
Step-by-step explanation:
You plug in the numbers to get the answer.
cos⁻¹(0.6) = 2π/365t
0.927, 5.356 = 2π/365t
t = 54 or 311

There are 16 entrees available at a restaurant. From these, Archie is to choose 6 for his party. How many groups of 6 entrees can he choose, assuming that the order of the entrees chosen does not matter ?
Answer: 8008
Step-by-step explanation:
Total entrees = 16
Number of entrees to choose = 6
Since order does not matter , so we combinations .
Number of combinations to choose r things out of n = [tex]C(n,r)=\dfrac{n!}{r!(n-r)!}[/tex]
Then, total ways to choose 6 entrees = [tex]C(16,6)=\dfrac{16!}{6!10!}[/tex]
[tex]=\dfrac{16\times15\times14\times13\times12\times11\times10!}{(720)10!}\\\\= 8008[/tex]
Hence, the required number of ways= 8008

Help me please thank y’all
Answer:
45 degrees
Step-by-step explanation:
We know that angle 4 equals angle 2 because corresponding angles are congruent.
So x+30 = 2x+15,
We subtract 15 from both sides,
x + 30 - 15 = 2x + 15 - 15
x + 15 = 2x
Now we subtract x from both sides,
x - x + 15 = 2x - x
15 = x
x = 15 degrees
So we plug this in angle 4,
15 + 30 = 45 degrees

It is believed that 11% of all Americans are left-handed. A college needs to know the number of left-handed desks to place in the large instructional lecture halls being constructed on its campus. In a random sample of 140 students from that college, whether or not a student was left-handed is recorded for each student. The college wants to know if the data provide enough evidence to show that students at this college have a lower percentage of left-handers than the general American population. State the random variable, population parameter, and hypotheses. State the Type I and Type II errors in the context of this problem.
Answer:
a) State the random variable
Random variable : x
which refers to a randomly selected student from the college that is left-handed.
b) state population parameter
population parameter : P
which is the percentage of all students from the college that are left handed
c) state the hypotheses
The hypothesis are;
Null hypothesis H₀ : p = 0.11
Alternative hypothesis H₁ : p > 0.11
d) State the Type I error in the context of this problem.
Type - I Error: Rejecting that the % of all the students from the college that are left-handed is 11% when actually the % is really 11%

What does it mean if an x (input) or y (output) value doesn't make sense? What does it look like on a graph? What happens in the equation?
Answer:
It is not a function.
Step-by-step explanation:
If the x input or the y output in the given equation have no meaning or does not have any sense, then it will not form a function. We need to see if there are two of the x - intercept which are same. Then the graph will be a straight vertical line. Also the slope of the function cannot be determined.
If f(x) = 2x + 2 and g(x) = x2 - 1, find (f - g)(x).
Answer:
(f - g)(x) = - x² + 2x + 3Step-by-step explanation:
f(x) = 2x + 2
g(x) = x² - 1
To find (f - g)(x) subtract g(x) from f(x)
That's
(f - g)(x) = 2x + 2 - [ x² - 1]
(f - g)(x) = 2x + 2 - x² + 1
Group like terms
That's
(f - g)(x) = - x² + 2x + 2 + 1
We have the final answer as
(f - g)(x) = - x² + 2x + 3Hope this helps you
