Answer: B) 3.875

Step-by-step explanation:

To start off, finding the mean is the AVERAGE. To find the average, you must add all of the values, and divide by however many values there are (in this case, there are 12) So first add all of the values:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2+2.2+2.5+3.1+3.3+3.4+4.1+4.1+4.5+5+5.6+6.7 = 46.5 (or 46.50)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

next, you divide 46.5 by however many values there are (in this case, there are 12)

So, 46.5 / 12 is equal to 3.875

This tells us that the average distance of the throw is 3.875 feet

Therefore, the correct answer is B.3.875 feet; The value means that a typical throw of the ball results in 3.875 feet.

Answer:

To determine its end behavior, look at the leading term of the polynomial function. Because the power of the leading term is the highest, that term will grow significantly faster than the other terms as x gets very large or very small, so its behavior will dominate the graph.

Answer:

y = 15

Step-by-step explanation:

We need to solve for k

y = x

21 = 7k  Divide both sides by 7 to solve for k

3 = k

y = xk

y = 5(3)

y = 15

Step-by-step explanation:

Answer: down below...

Step-by-step explanation:

Exercise 1:

Income = $83.465

Tax paid at 5.05% means, whatever your income is, you gotta pay 5.05% of it as a tax.

5.05% = \(\frac{5.05}{100}\)

\(\frac{5.05}{100}*$83.465\)

\(0.0505*$83.465\)

If you do the calculations it should give you a $4,214.9825 tax

"Income tax paid at 9.15%"

\(\frac{9.15}{100}*83.465\)

\(0.0915*83.465\)

The 9.15% tax = $7,637.0475

"Total income tax paid"

This will just be the sum of the two taxes.

$4,214.9825+$7,637.0475 = $11,852.03 (sum of taxes)

Exercise 2:

Purchase price = $347.000

Selling price = $863.000

As you can see, they purchased the property for $347.000 and sold it for $863.000 which made them a lot of money in profit :)

That's what the Difference is.

Difference = $863.000-$347.000

Difference = $516,000

I don't really understand what capital gains are, because I'm 13, but I suppose I gotta calculate 50% of the profit that the banker has made.

\(\frac{50}{100}*$516.000\)

\(\frac{5}{1}*$51.600\)

\(5*$51.600\)

"Capital gains" = $258,000

I don't really know if this is the correct answer for capital gains, but I am pretty sure I did well on the other ones.

Hope I helped you :] !

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Answer:

We can identify which case it is by looking at our results. If we end up with the same term on both sides of the equal sign, such as 4 = 4 or 4x = 4x, then we have infinite solutions. If we end up with different numbers on either side of the equal sign, as in 4 = 5, then we have no solutions.Step-by-step explanation:

Answer: $2.5

Step-by-step explanation:

The art museum charges a one-time fee of $8.25 plus $2.25 per month.

So, the cost function for membership for x months in the art museum f(x) = 8.25 + 2.25x .............. (1)

Again, the science museum charges a one-time fee of $10.75 plus $3.5 per month.

Hence, the cost function for membership for x months in the science museum g(x) = 10.75 + 3.5x ........... (2)

So, from both the equations it is clear that for only joining the monthly charges are zero.

So, f(0) = 8.25 and g(0) = 10.75.

Therefore, Barrett will save by joining the art museum instead of the science museum by $(10.75 - 8.25) = $2.5. (Answer)

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

Step-by-step explanation:

The area of the parallelogram given in the image is 72 square units.

The area of a parallelogram is taken as base × height because it can be divided into two different parts and then reshuffled to make a rectangle, whose area is also base × height.

We know that the area of a parallelogram = base × height  ......(i)

Also, we are given quantities for base = 6 units

and height = 12 units

So, putting the values in equation (i), we get

⇒ area = base × height

⇒ area = 6 × 12

⇒ area = 72 square units

So, the area of the parallelogram given is 72 square units.

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Answer:

1) 9/20

2) 5/11

Step-by-step explanation:

For the first question: We read the number "0.45" as "45 hundredths," and we write it as the fraction 45/100. Of course, since 45 and 100 share the common factor 5, we can reduce this fraction by dividing the numerator and denominator by 5 to get the reduced form 9/20.

For our second problem, we need to perform a bit of "mathematical surgery" to find the appropriate fraction for x = 0.454545... First, the dots tell us that this fraction is repeating - those 45s will keep going on and on forever. When we multiply x by 100, then, we move the decimal two places to the right, but the repeating part still remains, giving us

\(100x=45.454545\dots\)

From here, we can "surgically remove" the repeating bit using our original value of x:

\(100x-x=45.454545\dots-0.454545\dots\\99x=45\)

And from here, we just have to divide both sides of the equation by 99 to solve for x:

\(99x=45\\x=45/99\\x=5/11\)

Answer:

1) 36

2) 81

Step-by-step explanation:

#1 you first have to figure out how much it is receding by. The first one is 100 - 19. The second is 81 - 17. The third is 64 - 15. So the forth one is 49 - 13=49

#2 is just times each number by three. You can tell becuase the first number is 1. And the next is 3. So 27 x 3= 81. (81 x 3=243)

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

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

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.
