Calculate the mean of the number set 5 10 12 4 6 11 13 5

Answers

Answer 1
For calculating the mean, you want to add up all of the numbers then divide by how many numbers there are. So you'd do:

5+10+12+4+6+11+13+5 then divide that by 8

The answer to your question is: 8.25

What reason explains why (-6,8) must also be a point on the graph?

Answers

where are the reasons

The owner of a candy store wants to mix some peanuts worth $3 per pound, some cashews worth $10 per pound, and some Brazil nuts worth $9 per pound to get 50 pounds of a mixture that will sell for $6.80 per pound. She uses 10 fewer pounds of cashews than peanuts. How many pounds of each did she use?

Answers

let
x = pounds of peanuts
y = pounds of cashews
z = pounds of Brazil nuts.

The total pounds is 50, therefore
x + y + z = 50                   (1)

The total cost is $6.60 per pound for 50 pounds of mixture.
The total is equal to the sum of the costs of the different nuts.
Because the cost for peanuts, cashews, and Brazil nuts are $3, $10, and $9 respectively, therefore
3x + 10y + 9z = 50*6.8
3x + 10y + 9z = 340         (2)

There are 10 fewer pounds of cashews than peanuts, therefore
x = y + 10                         (3)

Substitute (3) into (1) and (2).
y + 10 + y + z = 50
2y + z = 40                     (4)
3(y + 10) + 10y + 9z = 340
13y + 9z = 310                (5)

From (4),
z = 40 - 2y          (6)
Substitute (6) into (5).
13y + 9(40 - 2y) = 310
-5y = -50
y = 10
z = 40 - 2y = 40 - 20 = 20
x = y + 10 = 20

Answer:
Peanuts:     20 pounds
Cashews:   10 pounds
Brazil nuts: 20 pounds

• capital one is advertising a 60-month, 5.99% apr motorcycle loan. if you need to borrow $8000 to purchase your dream harley davidson, what will your monthly payment be?

Answers

Given:
P = $8000, the principal
r = 5.99% = 0.0599, the interest rate
t = 60 months = 5 years, the duration
Assume n = 12, monthly compounding.

n*t = 12*5 = 60
r/n = 0.0599/12 = 0.004992

The total value of the loan is
A = P(1 + r/n)⁶⁰
    = 8000(1.004992)⁶⁰
    = 10785.434

Monthly payment = 10785.434/60 = $179.76

Answer: $179.46

Answer:

The monthly payment  is $ 154.29

Step-by-step explanation:

Given : time period = 60 months

Annual interest rate = 5.99%

Amount to be borrowed = $8000

We have to calculate the monthly payment.

We know ,

[tex]P=\dfrac{A\cdot \frac{i}{12}}{1-(1+\frac{i}{12})^{-n}}[/tex]

We have,

interest rate = 5.99% = 0.0599

Amount = $8000

time period = 60 months

P is monthly payment.

[tex]P=\dfrac{8000\left(\frac{0.059}{12}\right)}{1-\left(1+\frac{0.059}{12}\right)^{\left(-60\right)}}[/tex]

Simplify, we get,

P = 154.29

Thus, the monthly payment  is $ 154.29

A campground has cabins that can each hold 28 campers. There are 148 campers that are visiting the campground. How many cabins are full if there are 28 campers in each cabin? Please help i'm desperate and i'm marking most brainliest.

Answers

Final answer:

To find the number of full cabins, divide the total number of campers by the number of campers in each cabin. Round the answer up to the nearest whole number.

Explanation:

To find the number of full cabins, you can divide the total number of campers by the number of campers in each cabin.

148 campers / 28 campers per cabin = 5.2857 cabins

Since we can't have fractional cabins, we round up to the nearest whole number, which is 6.

Therefore, there are  that are full.

Final answer:

There are 6 cabins that are full.

Explanation:

To find the number of cabins that are full, we need to divide the total number of campers by the number of campers each cabin can hold. In this case, there are 148 campers and each cabin can hold 28 campers.

We can solve this problem by dividing 148 by 28: 148 ÷ 28 = 5.2857.

Since we cannot have a fraction of a cabin, we round up to the nearest whole number. Therefore, there are 6 cabins that are full.

Calc find the maximum of f(x, y) = y2 + xy â x2 on the square 0 ⤠x ⤠6, 0 ⤠y ⤠6.

Answers

Presumably, [tex]f(x,y)=y^2+xy-x^2[/tex]. We have

[tex]\begin{cases}f_x=y-2x=0\\f_y=2y+x=0\end{cases}[/tex]
[tex]y=2x\implies 2y+x=4x+x=0\implies x=0\implies y=0[/tex]

so on this region, [tex]f(x,y)[/tex] has only one critical point at (0, 0)[/tex]. Since this point lies on the boundary, we can ignore it for the moment.

Along the boundaries, we have four scenarios to consider:

[tex]x=0\implies f(0,y)=y^2[/tex]
[tex]x=6\implies f(6,y)=y^2+6y-36=(y+3)^2-45[/tex]
[tex]y=0\implies f(x,0)=-x^2[/tex]
[tex]y=6\implies f(x,6)=36+6x-x^2=-(x^2-6x-36)=45-(x-3)^2[/tex]

In the first case, [tex]y^2[/tex] is increasing over [tex]0\le y\le6[/tex], so we'll attain when [tex]y=6[/tex] a value of [tex]f(0,6)=36[/tex].

In the second case, [tex](y+3)^2-45[/tex] attains a minimum when [tex]y=-3[/tex], and would be increasing to either side. This would mean at [tex]y=6[/tex] we get [tex]f(6,6)=36[/tex].

In the third case, [tex]-x^2[/tex] attains a max at [tex]x=0[/tex], which would yield [tex]f(0,0)=0[/tex].

In the fourth case, [tex]45-(x-3)^2[/tex] attains a max at [tex]x=3[/tex], giving a value of [tex]f(3,6)=45[/tex].

This means the absolute maximum of [tex]f(x,y)[/tex] over the square is attained along the boundary [tex]y=6[/tex] when [tex]x=3[/tex], with a maximum value of [tex]f(3,6)=45[/tex].

To find the maximum of the function f(x, y) = y² + xy – x² on the square 0 ≤ x ≤ 6, 0 ≤ y ≤ 6, we need to find the critical points by taking the partial derivatives with respect to x and y.

To find the maximum of the function f(x, y), we need to find the critical points by taking the partial derivatives with respect to x and y:

[tex]f_x[/tex] = y - 2x

[tex]f_y[/tex] = 2y + x

Setting these derivatives equal to zero and solving for x and y, we get the critical point (2,2). To determine if this point is a maximum, minimum, or point of inflection, we can use the second derivative test. Taking the second partial derivatives:

[tex]f_{xx[/tex] = -2, [tex]f_{yy[/tex] = 2, [tex]f_{xy[/tex] = 1

Using the discriminant D = [tex]f_{xx} \times f_{yy} - {(f_{xy})}^2[/tex], we have D = [tex](-2) \times 2 - {1}^2[/tex] = -4. Since D is negative, the critical point (2,2) is a saddle point, which means there is no maximum or minimum on the given square.

What Is two thirds of a straight angle

so 2/3 of a straight angle is 2/3 of 180..." of " means multiply
2/3(180) = 360/3 = 120 <==

Two thirds of a straight angle is calculated as 120 degrees.

Two thirds of a straight angle can be calculated by first understanding that a straight angle is equal to 180 degrees. When we want to find a fraction of a given angle, we multiply the fraction by the total degree measure of that angle.

In this case, to find two thirds of a straight angle, we multiply 180 degrees by 2/3.
Here is a step-by-step explanation of the calculation:

Understand that a straight angle equals 180 degrees.

Multiply 180 degrees by the fraction 2/3:

(180 degrees) * (2/3) = 120 degrees.

72 - 36 = 4x

36 = 4x

The simplified expression of 4 +9 "/" 3 "/" 2 x 3 + (3 + 1) x 4 is 17, following the order of operations or PEMDAS.

To simplify the given expression, follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

The original expression is 4 +9 / 3 / 2 x 3 + (3 + 1) x 4. First, address operations inside parentheses: (3+1) equals 4. The expression becomes 4 +9 / 3 / 2 x 3 + 4 x 4.

Next, handle the multiplication and division from left to right: 9 / 3 equals 3, and 2 x 3 equals 6. Then, 4 x 4 equals 16. This turns our expression into 4 + 3 - 6 + 16.

Finally, perform addition and subtraction from left to right: 4 + 3 equals 7, 7 - 6 equals 1, and 1 + 16 equals 17. Therefore, the simplified expression is 17.
