Answer:

Total output= H5, H6,T5, T6

Step-by-step explanation:

Bailey will roll a number cube and flip a coin for a probability experiment.

The faces of the cube are labeled 1-6= 6 possible outcomes

The coin can land on heads or tails= 2 possible outcomes

If Bailey rolls the number cube once= 1 output

and flips the coin once = 1 output

Total output will be combined outcome of cube and coin:

       possible outcome of cube= 1, 2, 3 , 4 , 5, 6

       possible outcome of coin= H, T

                                    (H for heads and T for tails)

Total output =possible combined outcome of cube and coin= H1, H2, H3 , H4 , H5, H6, T1, T2, T3 , T4 , T5, T6

Now

the outcomes in which the number cube lands on a number greater than :

reduces the total required output by removing the combination when the number cube lands on a number less than or equals to 4

therefore removing H1, H2, H3 , H4 and T1, T2, T3 , T4 from the total outcome will result in following list:

Total output= H5, H6,T5, T6 i.e.

5, Heads

5, Tails

6, Heads

6, Tails !

Y=2x should be correct

Y is two times the value of X, which can be represented as Y = 2X.

This indicates a directly proportional relationship between Y and X, where Y increases as X increases.

Answer: Third option

[tex]V_s=14\ m^3[/tex]

Step-by-step explanation:

The volume of a sphere is:

[tex]V_s=\frac{4}{3}\pi r^3[/tex]

Where r is the radius of the sphere

The volume of a cylinder is:

[tex]V_c = \pi r ^ 2 h[/tex]

Where h is the height of the cylinder and r is the radius

We assume that the height of the sphere is its diameter or 2 times its radius.

Then [tex]2r = h[/tex]

[tex]V_c= 21\ m^3=\pi r ^ 2 h[/tex]

[tex]V_c= 21\ m^3=\pi r ^ 2(2r)[/tex]

We solve the equation for r

[tex]\frac{21}{2\pi}=r ^ 3\\\\r= \sqrt[3]{\frac{21}{2\pi}}\\\\r=1.495\ m[/tex]

The radius of the cylinder is equal to the radius of the sphere

Finally

[tex]V_s=\frac{4}{3}\pi (1.495)^3[/tex]

[tex]V_s=14\ m^3[/tex]

Answer:

152 kids and 30 adults

Step-by-step explanation:

To solve this, we must create a system of equations

Suppose:

x = the number of adults

y = the number of children

We know that a total of 182 people attended the trip.

So:

x + y = 182

This equation represents the number of people attending the trip.

To find out the cost, look at the problem.

It costs 13$ for one adult and 8$ for a child.

So:

13x + 8y = 1606

This equation represents the total cost to attend the museum. Now, we must solve.

[There are two ways to solve a system of equations, substitution and adding/subtracting. I will use adding and subtracting. The steps to solving the system of equations is in the photos below]

The final answer is 152 kids and 30 adults

To express the area of a rectangle as a monomial, multiply the length and width. This gives 30m6.

The area of a rectangle is calculated by multiplying its length and width. For a rectangle with length 5m4 and width 6m2, to express the area as a monomial, you multiply these two together. So, the area A = 5m4 * 6m2.

In terms of exponents, when we multiply terms with the same base (in this case, m), we add up the exponents. Thus, A = 30m4+2 = 30m6. Therefore, the area of the rectangle expressed as a monomial is 30m6.

Answer:

4.5 in²

Step-by-step explanation:

Given that the triangles are similar then

linear ratio of corresponding sides = 3 : 4, then

ratio of corresponding areas = 3² : 4² = 9 : 16

let the area of ΔEDF be x then by proportion

[tex]\frac{x}{9}[/tex] = [tex]\frac{8}{16}[/tex] ( cross- multiply )

16x = 72 ( divide both sides by 16 )

x = 72 ÷ 16 = 4.5

Area of ΔEDF = 4.5 in²

These angles are vertical angles meaning that they are equal to each other. Here is the equation for this problem:

x + 40 = 3x

Combine like terms

(x-x) + 40 = 3x - x

40 = 2x

Isolate x

40/2 = 2x/2

x = 20

The mean is the average, add the numbers together and divide by the quantity of numbers:

10 + 12 + 15 + 12 + 13 + 11 + 10 + 13 = 96

96 / 8 = 12

The mean is 12

The median is the middle value.

Rearrange the numbers from smallest to largest:

10 , 10 , 11 , 12 , 12 , 13 , 13 , 15

There are an even amount of numbers, so find the middle two values, add together and divide by 2:

12 + 12 = 24 /2

Median = 12

Answer:

The output expected in 2016 is 1.6488 x 10 ^9 or 1.6488 billion

Step-by-step explanation:

The output is decreased by 8.4% from 2006 to 2016.

Amount of output in 2006 = 1.8 billion dollars

Decrease in output = 8.4%

We need to find the 8.4% of 1.8 billion dollars and then subtract the result from 1 billion dollars.

We know 1.8 billion = 1,800,000,000 or 1.8 x 10^9

8.4% of 1.8 billion = 8.4/100 * (1.8 x 10^9)

                             = 151200000

So, Output expected in 2016 = 1.8 x 10^9 - 151200000

                                                 = 1648800000 or 1.6488 x 10 ^9

So, the output expected in 2016 is 1.6488 x 10 ^9 or 1.6488 billion.

[tex](f + g) (2) = -4[/tex]

Step-by-step explanation:

We have the functions

[tex]F(x) =-3x^2-2[/tex]

And

[tex]g(x)=4x+2[/tex]

We want to find [tex](f + g) (x)[/tex]

Then

[tex](f+g)(x) = f(x) + g(x)\\\\(f+g)(x) = -3x^2-2 + 4x+2\\\\(f+g)(x)= -3x^2 +4x[/tex]

finally we find [tex](f + g) (2)[/tex]

[tex](f + g) (2) = -3(2)^2 + 4(2)\\\\(f + g) (2) = -3*4 + 8\\\\(f + g) (2) = -12+ 8\\\\(f + g) (2) = -4[/tex]

Answer:

(f+g)2 = 20

Step-by-step explanation:

18. if F(x) =-3x2-2 and g(x)=4x+2 what is value of (f+g)(2)?

We know, (f+g)2= f(2) + g(2)

We will put 2 in the place of x for f(x) and g(x) and then find their result.

Solving:

(f+g)2= f(2) + g(2)

         =3(2)^2 -2 + 4(2) +2

         = 3(4) -2 + 8 +2

         = 12 -2 +8 +2

         = 20

So, (f+g)2 = 20

While 'yeet' is not an academically defined term, it typically refers to the act of throwing something with force. Drawing from a story on LibreTexts, one can learn the technique for effectively throwing objects such as a horseshoe, which involves grip, stance, focus on the target, and a smooth release.

To throw a horseshoe effectively, similar to learning how to "yeet," one must:

Hold the horseshoe in a comfortable but firm grip with your thumb along one of the sides of the horseshoe.

Stand at the designated throwing line and focus on the stake you're aiming at.

Swing your arm forward smoothly and release the horseshoe when your hand is about waist-high, keeping your eyes on the target for accuracy.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

618 runners registered for the marathon. Of these runners, 0.8% completed the race in under 2 hr 15 min.

Let "N" be the number of runners who completed the race. Then the equation is given as,

0.8% = (N / 618) x 100

0.008 = N / 618

N = 0.008 x 618

N = 4.944

N ≈ 5

To find the monthly rate of decay, we convert the annual decay rate of 8% to a monthly rate using the formula for compound interest. The monthly rate comes out to be approximately -0.6734%, which is closest to the provided option of -0.667%.

To find the monthly rate of decay for a car that depreciates 8% annually, we should convert the annual decay rate to a monthly decay rate assuming compound interest. This calculation involves using the formula for converting an annual percentage rate to a monthly rate when compounded monthly:

Monthly rate = [tex](1 + Annual rate)^(1/12)[/tex] - 1

Substitute the given annual rate of decay (-0.08 or -8%) into the formula:

Monthly rate = [tex](1 - 0.08)^(1/12)[/tex] - 1

This calculation gives us:

Monthly rate = [tex](0.92)^(1/12)[/tex] - 1
Approximately -0.006734
