Answer:
La mínima calificación que Stephen puede recibir en el quinto examen para obtener una A en el curso es 98.
Step-by-step explanation:
La media (también llamada promedio o media aritmética) de un conjunto de datos es una medida de posición central. Es el valor obtenido al sumar todos los datos y dividir el resultado entre el número total de datos.
En este caso, el número total de datos es 5 y el valor de los datos de los cuales debes obtener el problema es 92, 87, 96, 77 y un valor desconocido de un quinto examen. Y sabes que este valor debe ser igual o mayor a 90.
Esto se expresa matemáticamente como:
[tex]\frac{92+87+96+77+nota}{5}[/tex]≥90
donde "nota" es la mínima calificación que Stephen puede recibir en el quinto examen para obtener una A en el curso.
Resolviendo:
[tex]\frac{352+nota}{5}[/tex]≥90
352+nota≥90*5
352+nota≥450
nota≥450 - 352
nota≥98
La mínima calificación que Stephen puede recibir en el quinto examen para obtener una A en el curso es 98.

Manuela is having mugs made for a fundraiser. The Cup Company will make them for $4 each plus a $30 set-up charge. Mugs Are Us will make them for $4.50 each with no set-up charge. At what amount of mugs will the price be the same for both companies?
Answer:
The price will be the same for both companies at 60 mugs
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the rate of changeb is the fixed amountAssume that the number of mugs is x and the total cost of them is $y
∵ The Cup Company will make them for $4 each plus a $30
set-up charge
∴ The cost per mug = $4
∴ m = 4
∴ The fixed amount = $30
∴ b = 30
∵ x is the number of mugs
∵ y is the cost of them
→ Substitute the values of m and b in the form of the equation
∴ y = 4x + 30 ⇒ (1)
∵ Mugs Are Us will make them for $4.50 each with no set-up charge
∴ The cost per mug = $4.50
∴ m = 4.5
∴ The fixed amount = 0
∴ b = 0
∵ x is the number of mugs
∵ y is the cost of them
→ Substitute the values of m and b in the form of the equation
∴ y = 4.5x + 0
∴ y= 4.5x ⇒ (2)
∵ The price be the same for both companies
→ Equate the right sides of (1) and (2)
∴ 4.5x = 4x + 30
→ Subtract 4x from both sides
∵ 4.5x - 4x = 4x - 4x + 30
∴ 0.5x = 30
→ Divide both sides by 0.5
∴ x = 60
∴ The price will be the same for both companies at 60 mugs

Evaluate the function f\left(x\right)=5x+2\mid11-5x\mid-4f(x)=5x+2∣11−5x∣−4 for x = -5.
Answer:
[tex]f\left(5\right) = 43[/tex]
Step-by-step explanation:
Given
[tex]f\left(x\right)=5x+2\mid11-5x\mid-4[/tex]
Required
Solve for x = -5
This implies that we substitute -5 for x in [tex]f\left(x\right)=5x+2\mid11-5x\mid-4[/tex]
[tex]f\left(5\right)=5(-5)+2\mid11-5(-5)\mid-4[/tex]
Open all brackets
[tex]f\left(5\right) = -25+2\mid11+25\mid-4[/tex]
[tex]f\left(5\right) = -25+2\mid36\mid-4[/tex]
Absolute value of 36 is 36; Wo, we have:
[tex]f\left(5\right) = -25+2*36-4[/tex]
[tex]f\left(5\right) = -25+72-4[/tex]
[tex]f\left(5\right) = 43[/tex]

The Parry Glitter Company recently loaned $300,000 to FIX 92, a local radio station. The radio station signed a noninterest-bearing note requiring the $300,000 to be repaid in three years. As part of the agreement, the radio station will provide Parry with a specified amount of free radio advertising over the three-year term of the note.
The focus of this case is the valuation of the note receivable by Parry Glitter Company and the treatment of the "free" advertising provided by the radio station. The mission of this discussion is to reach a consensus on the appropriate note valuation and accounting treatment of the free advertising.
Answer:
The Parry Glitter Company
The Parry Glitter Company should record the Notes Receivable as $300,000.
It should also record the interest receivable per year as $24,000 and the advertising cost as $24,000 per year. These bring into the accounting records the interest revenue and also the advertising expense, which eventually cancel each other.
Step-by-step explanation:
a) Data and Calculations:
Notes Receivable = $300,000
If the notes receivable are repaid at the end of 3 years and it is assumed that the interest on the notes receivable = 8%
Therefore, the cost of the free advertising will be equal to $24,000 ($300,000 * 8%), which is the cost of the interest to the radio station.
Claire is putting up a fence around her rectangular garden. The length is four less than double the width. The perimeter is 22 feet. Find the dimensions of the garden.
PLZ ANSWER THIS FAST, ITS NOT ABOUT THE POINTS.
Answer:
The dimensions are 6 by 5 feet.
Length = 6 feet.
Width = 5 feet.
Step-by-step explanation:
Let the length = L
Let the width = W
Perimeter of a rectangle = 2L + 2W
Translating the word problem into an algebraic equation, we have;
L = 2W - 4 ........equation 1
22 = 2L + 2W .......equation 2
Substituting the value of "L" into equation 2, we have;
22 = 2(2W - 4) + 2W
22 = 4W - 8 + 2W
22 + 8 = 6W
30 = 6W
W = 30/6
Width, W = 5 feet.
To find the length, L
Substituting the value of "W" into equation 1, we have;
L = 2W - 4
L = 2(5) - 4
L = 10-4
Length, L =6 feet
Therefore, the dimensions of the garden are 6 by 5 feet.

If a rectangular garden is 35 ft. by 40 ft., how many feet of fence are needed to enclose it? ft.
Answer:
if youre saying that the length and width of the garden is 35 by 40, you would need 150 ft of fence.
Step-by-step explanation:
35(2) + 40(2)
70 + 80
150
The length of the fence that will be needed to enclose the rectangular garden is 150 ft.
What is a rectangle?A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. A rectangle is always a parallelogram and a quadrilateral but the reverse statement may or may not be true.
Given that the rectangular garden is 35 ft. by 40 ft. The fencing will be done on the sides of the garden, therefore, along the perimeter of the rectangle,
Perimeter of rectangle = 2 (35ft +40ft)
= 2 (75ft)
= 150 ft
Hence, the length of the fence that will be needed to enclose the rectangular garden is 150 ft.

The graph shows the distribution of the number of text messages young adults send per day. The distribution is approximately Normal, with a mean of 128 messages and a standard deviation of 30 messages.
What percentage of young adults send more than 158 text messages per day?
16%
34%
68%
84%
Answer:
16%
Step-by-step explanation:
From the graph of distribution of the number of text messages
Young adults send more than 158 text messages per day is 16%
Given :
The distribution is approximately Normal, with a mean of 128 messages and a standard deviation of 30 messages.
Given 158 text messages . so x is 168
Now we find out z -score
[tex]z=\frac{x-mean}{standard\; deviation }[/tex]
Replace the values and find out z
[tex]z=\frac{158-128}{30} =1[/tex]
the value of z=1
Lets use the standard deviation table that gives area on the left
the table gives the percentage of adults less than 158
z-score value for z=1 is 0.8413
Now, percentage of young adults send more than 158 text messages
Percent (more than 158)=1- P(less than 158)=[tex]1-0.8413=0.1587[/tex]
To get percentage we multiply by 100
[tex]0.1587 \cdot 100= 15.87= 16[/tex]
Young adults send more than 158 text messages per day is 16%

5. MAPPING Ben and Kate are making a
map of their neighborhood on a piece of
graph paper. They decide to make one
unit on the graph paper correspond to
100 yards. First, they put their homes
on the map as shown below.
a. How many yards apart are Kate's and Ben's homes?
b. Their friend Jason lives exactly halfway between Ben and Kate. Mark the location of Jason's home on the
map. if my answers are wrong, correct me. i just used a pdf and idk if they’re right. ty ❤️
Answer:
a. 1,000 yards
b. (2, -1)
Step-by-step explanation:
Coordinates of Ben's House = (6, 2)
Coordinates of Kate's House = (-2, -4)
a. Number of yards between Kate and Ben's House using instance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex].
[tex] d = \sqrt{(6 -(-2))^2 + (2 -(-4))^2} [/tex]
[tex] d = \sqrt{(8)^2 + (6)^2} [/tex]
[tex] d = \sqrt{64 + 36} [/tex]
[tex] d = \sqrt{100} [/tex]
[tex] d = 10 units [/tex]
1 unit = 100 yards
Therefore, 10 units = 1,000 yards.
Kate and Ben's House are 1,000 yards apart.
b. Since Jason's home is halfway between Ben and Kate's House, therefore, Jason's location is the midpoint between Ben and Kate's House. Use the midpoint formula to calculate the coordinates of Jason's location on the map, using (6, 2) and (-2, -4).
