Answer:

P = 1/2 = 0.5

Step-by-step explanation:

Total amount of cans = 100

Cans of cola = 34

Cans of orange soda = 50

Cans of ginger ale = 12

Cans of root beer = 4

Probability of selecting

- a can of cola = 34/100 = 0.34

- a can of orange soda = 50/100 = 0.5

- a can of ginger ale = 12/100 = 0.12

- a can of root beer = 4/100 = 0.04

Since we are asked the probability that the can selected is a root beer​, cola, or ginger ale, we need to add together the probabilities of each.

P = 0.04 + 0.34 + 0.12 = 0.5 = 1/2

Answer:  $4080

Step-by-step explanation:  25 x 11 = 275,  4355-275 = 4080

The Haugh family will need to pay $4,080 in the 12th month if they make only the minimum payment for 11 months. The monthly payment they should pay is $362.92 (rounded to the nearest cent).

A) To find out how much the Haugh family will need to pay in the 12th month if they make only the minimum payment for 11 months, we need to calculate the remaining balance after 11 months. The total cost of the hot tub is $4,355. The minimum monthly payment is $25, so the remaining balance after 11 months is $4,355 - 11 * $25 = $4,080. Therefore, the Haugh family will need to pay $4,080 in the 12th month.

B) To calculate the monthly payment, we divide the total cost of the hot tub by the number of months (12). So, the monthly payment is $4,355 / 12 = $362.92. However, since there is a minimum payment requirement of $25, the Haugh family should pay $362.92 each month (rounded to the nearest cent).

the expanded form of (3x + 4)(2x − 5) is 6x² - 7x - 20. The third option is the correct option.

The simplified form of (3x + 2y) - (x + 2y) is 2x. The correct option is the third option.

3x + 4y equals 36. The third option is the correct option.

To evaluate f(x) = 4x + 3x² - 5, f(x) evaluates to -1. The last option is the correct option.

The Breakdown

To expand the expression (3x + 4)(2x − 5), you can use the distributive property:

(3x + 4)(2x − 5) = 3x(2x) + 3x(-5) + 4(2x) + 4(-5)

Now, simplify each term:

= 6x² - 15x + 8x - 20

Combine like terms:

= 6x² - 7x - 20

So, the expanded form is 6x² - 7x - 20.

To simplify the expression (3x + 2y) - (x + 2y), we can remove the parentheses and combine like terms:

(3x + 2y) - (x + 2y) = 3x + 2y - x - 2y

The terms "2y" and "-2y" cancel each other out:

= 3x - x

Simplifying further:

= 2x

Therefore, the simplified form of (3x + 2y) - (x + 2y) is 2x.

To find the value of 3x + 4y, we need to solve the given equation and then substitute the values into the expression.

Given: 1/2x + 2/3y = 6

To eliminate the fractions, we can multiply the entire equation by the least common multiple (LCM) of the denominators, which is 6:

6 × (1/2x + 2/3y) = 6 × 6

This simplifies to:

3x + 4y = 36

Therefore, 3x + 4y equals 36.

To evaluate f(x) = 4x + 3x² - 5 when x = -2, we substitute -2 for x in the expression:

f(-2) = 4(-2) + 3(-2)² - 5

Simplifying:

f(-2) = -8 + 3(4) - 5

f(-2) = -8 + 12 - 5

f(-2) = -1

Therefore, when x = -2, f(x) evaluates to -1.

Answer:

(x + 5)² + (y + 7)² = 288

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

The radius is the distance from the centre (- 5, - 7) to the point on the circle (7, 5)

Use the distance formula to calculate r

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 5, - 7) and (x₂, y₂ ) = (7, 5)

r = [tex]\sqrt{(7+5)^2+(5+7)^2}[/tex] = [tex]\sqrt{12^2+12^2}[/tex] = [tex]\sqrt{288}[/tex]

Hence

(x - (- 5))² + (y - (- 7))² = ([tex]\sqrt{288}[/tex])², that is

(x + 5)² + (y + 7)² = 288

Answer:

C. 6 feet

Step-by-step explanation:

The answer is:

The correct option is B. the string is 3.9 feet long.

To solve the problem, we need to use the given formula, substituting "T" equal to 2.2 seconds, and then, isolating "L".

Also, we need to remember the formula to calculate a simple pendulum:

[tex]T=2\pi \sqrt{\frac{L}{g} }[/tex]

Where,

T, is the period in seconds

L, is the longitud in meters or feet

g, is the acceleration of the gravity wich is equal to:

[tex]g=9.81\frac{m}{s^{2} }[/tex]

or

[tex]g=32\frac{feet}{s^{2} }[/tex]

We are given the formula:

[tex]T=2\pi \sqrt{\frac{L}{32} }[/tex]

Where,

T, is the period of the pendulum (in seconds).

L, is the length of the string.

32, is the acceleration of the gravity in feet.

So, substituting "T" and isolating "L", we have:

[tex]2.2seconds=2\pi \sqrt{\frac{L}{32\frac{feet}{seconds^{2}} }}\\\\2\pi \sqrt{\frac{L}{32\frac{feet}{seconds^{2}}}}=2.2seconds\\\\\sqrt{\frac{L}{32\frac{feet}{seconds^{2}}}}=\frac{2.2seconds}{2\pi }[/tex]

Then, squaring both sides of the equation, to cancel the square root, we have:

[tex]\sqrt{\frac{L}{32\frac{feet}{seconds^{2} }}}=\frac{2.2seconds}{2\pi}\\\\(\sqrt{\frac{L}{32\frac{feet}{seconds^{2}}}})^{2}=(\frac{2.2seconds}{2\pi})^{2}=(0.35seconds)^{2} }\\\\\frac{L}{32\frac{feet}{seconds^{2}}}}=0.123seconds^{2}\\\\L=32\frac{feet}{seconds^{2}}*0.123seconds^{2}\\\\L=3.94feet=3.9feet[/tex]

Hence, we have that the answer is:

B. the string is 3.9 feet long.

Answer:

The coordinates of the solution that lies in quadrant IV are (2, -5)

Step-by-step explanation:

We have 2 equations, the first of an ellipse and the second of a circumference.

[tex]2x^2+y^2=33\\x^2+y^2+2y=19[/tex]

To solve the system solve the second equation for x and then substitute in the first equation

[tex]x^2+y^2+2y=19\\\\x^2 = 19 -y^2 -2y[/tex]

So Substituting in the first equation we have

[tex]x^2 = 19 -y^2 -2y\\\\2(19 -y^2 -2y)+y^2=33\\\\38 -2y^2-4y +y^2 = 33\\\\-y^2-4y+5=0\\\\y^2 +4y-5 = 0[/tex]

Now we must factor the quadratic expression.

We look for two numbers that multiply as a result -5 and add them as result 4.

These numbers are -1 and 5.

Then the factors are

[tex]y^2 +4y-5 = 0\\\\(y-1)(y+5) = 0[/tex]

Therefore the system solutions are:

[tex]y = 1[/tex]; [tex]y = -5[/tex]

In the 4th quadrant the values of x are positive and the values of y are negative.

So we take the negative value of y and substitute it into the system equation to find x

[tex]y=-5\\\\2x^2+(-5)^2=33\\\\2x^2 = 33-25\\\\2x^2 = 8\\\\x^2 = 4[/tex]

[tex]x = 2[/tex], and [tex]x= -2[/tex]

In the 4th quadrant the values of x are positive

So we take the positive value of x

the coordinates of the solution that lies in quadrant IV are (2, -5)

-2x=22 so x=-11

Then, y=2(-11)-3, so y=-25

So the solution would be (-11,-25).

Answer:

25%

Step-by-step explanation:

Assuming the catching of a fish is a random process and that the probability of catching any of the listed kinds of fish is proportional to their population, then the probability of catching a sturgeon is 50%. The probability of catching another one is also 50% (assuming the events are independent). So, the joint probability is the product of these:

0.50 × 0.50 = 0.25 = 25% . . . . . probability of catching 2 sturgeon in a row.

The probability of both fish being white sturgeon is 0.25.

To calculate the probability, we need to multiply the probabilities of catching a white sturgeon each time. Since 50% of the fish are white sturgeon, the probability of catching one is 0.5. Therefore, 0.5 multiplied by 0.5 equals 0.25.

A prism is a solid object having two identical bases, hence the same cross section along the length. Prism are called after the name of their base. On the other hand, a rectangular prism is a solid whose base is a rectangle.  Multiplying the three dimensions of a rectangular prism: length, width and height, gives us the volume of a prism:

[tex]V=L\times W\times H[/tex]

From the statement of the problem we know:

[tex]V=24ft^3 \\ \\ H=3ft \\ \\ W=W \\ \\ L=W+2[/tex]

So:

[tex]24=(W+2)(W)(3) \\ \\ 3W(W+2)=24 \\ \\ 3W^2+6W-24=0 \\ \\ From \ the \ Quadratic \ Formula: \\ \\ W_{12}=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ W_{12}=\frac{-6 \pm \sqrt{6^2-4(3)(-24)}}{2(3)} \\ \\ W_{1}=2 \\ \\ W_{2}=-4[/tex]

Since we can't have negative distance, the only valid option is [tex]\boxed{W=2ft}[/tex]

Answer:

a = -8

Step-by-step explanation:

We have been given the following radical expression;

[tex]\sqrt[3]{x^{10} }[/tex]

The radical can be expressed using the law of exponents;

[tex]\sqrt[n]{x}=x^{\frac{1}{n} }[/tex]

The radical can thus be re-written as;

[tex]\sqrt[3]{x^{10} }=(x^{10})^{\frac{1}{3} }[/tex]

Using the law of exponents;

[tex](a^{b})^{c}=a^{bc}[/tex]

The last expression becomes;

[tex](x^{10})^{\frac{1}{3} }=x^{\frac{10}{3} }=x^{3}*x^{\frac{1}{3} }\\\\=x^{3}\sqrt[3]{x}[/tex]

substituting x with -2 yields;

[tex]-2^{3}\sqrt[3]{-2}=-8\sqrt[3]{-2}[/tex]

False.

Replace x with -2 and simplify. 5(-2) + 3 = 13

Multiply. -10 + 3 = 13

Add. -7 = 13

This is not true, so -2 is not a solution, therefore the answer to the question is false.

Answer:

Company 1 is greater.

Step-by-step explanation:

Given,

The function that shows the production cost of company 1,

[tex]f(x)=0.15x^2-6x+400[/tex]

Differentiating with respect to x,

We get,

[tex]f'(x)=0.30x-6[/tex]

Again differentiating,

[tex]f''(x)=0.30[/tex]

For minimum or maximum,

f'(x) = 0,

[tex]\implies 0.3x-6=0[/tex]

[tex]\implies x = 20[/tex]

Since, at x = 20, f''(x) = Positive,

So, f(x) is minimum at x = 20,

⇒ Minimum cost in company 1 is,

[tex]f(20)=0.15(20)^2-6(20)+400[/tex]

[tex]=340[/tex]

Also, by the given table,

The minimum cost of company 2 is at x = 70,

g(70) = 55,

Since, 340 > 55,

Hence, Based on the given information, the minimum production cost for company 1 is greater.

Answer:

xy = 1

k = 79

Step-by-step explanation:

Question One

The first and third frames look to me to be the same. I'll treat them that way.

y = x^2                        Equate y = x^2 to the result of 2y + 6 = 2x + 6

2y + 6 = 2(x + 3)         Remove the brackets

2y + 6 = 2x + 6           Subtract 6 from both sides

2y = 2x                       Divide by 2

y = x

Now solve these two equations.

so x^2 = x                  

x > 0

1 solution is x = 0 from which y = 0. This won't work. x must be greater than 0. So the other is

x(x) = x                           Divide both sides by x            

x = 1                            

y = x^2                           Put x = 1 into x^2

y = 1^2                           Solve

y = 1                      

The second solution is

(1,1)

xy = 1*1

xy = 1

Answer: A

Question Two

square root(k + 2) - x = 0

Subtract x from both sides

sqrt(k + 2) = x                Square both sides

k + 2 = x^2                    Let x = 9

k + 2 = 9^2                    Square 9

k + 2 = 81

k = 81 - 2

k = 79
