The required mean number is 4 miles that Kiki cycled every day.

Given that,
The number of miles that Kiki cycled in a seven-week period Is shown: 6, 3, 9, 2, 4, 3, 1. What is the mean number of miles Kiki cycled is to be determined.

The average of the values is the ratio of the total sum of values to the number of values.

Mean = total sum of the reading/number of readings
Mean = (6 + 3 + 9 + 2  + 4 + 3 + 1) / 7

Mean = 28 / 7
Mean = 4

Thus, the required mean number is 4 miles that Kiki cycled every day.

Answer: 0.6 meters cubed.

Step-by-step explanation:

To find the answer to this, first find the volume of the cube.

Volume is equal to the side cubed. In this case, 1 cubed is 1, so the area of the cube is 1 meter cubed.

The depth of the water is 0.4 meters, so the water makes a shape of a rectangular prism, where the length and width are 1 meter, and the height is 0.4 meters.

The volume of a rectangular prism is l*w*h, so the volume of this rectangular prism is 0.4 * 1 * 1, or 0.4 meters cubed.

As such, the volume of the air in the tank is 1 - 0.4, or 0.6 meters cubed.

Answer:

0.6 meters CUBED

These decimals have a difference of 0.35 between them.

Answer:

Each of the pieces will be 0.5 feet long

Step-by-step explanation:

In this question, we are asked to calculate the individual length Anita will cut a ribbon 6 feet long into to ensure that each of the piece has the same length.

To calculate this, since we don not know what length each of the piece would be, we can say let the length of each of the pieces be x feet

Now, we know that there are 12 pieces that are equal in length. The length of all these 12 pieces would be 12 * x = 12x feet

Now what do we know again?

We also know that these 12x feet equals a total of 6 feet

mathematically therefore;

12x = 6

x = 6/12

x = 0.5 feet

Answer: Each piece will be 1/2 feet long.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given.

We simply have to divide the length of the ribbon (6) by the number of pieces that she wants to cut (12).

Mathematically speaking:

6 /12 = 1/2  

In conclusion, each piece will be 1/2 feet long.

Answer:

m+5=7

"A number m" will be a unknown nmber known as a variable. So it will be m.

"Increased by 5" is addition. So you are adding 5.

"Is 7" is equal to 7. it will be =7.

So when you put this together it will give you m+5=7

Step-by-step explanation:

Final answer:

After 30 years of monthly $250 contributions to a 401(k) with a 2% annual growth rate, the interest earned on the account is approximately $65,961.73.

Explanation:

To calculate the amount of interest earned in the 401(k) after 30 years with a 2% annual growth rate, we first need to figure out the future value of the account. We use the formula for the future value of an annuity, as the investments are made at regular intervals (monthly).

The formula is: FV = P *rac{(1 + r)^n - 1}{r}

Where:

FV is the future value of the annuity.

P is the payment amount per period.

r is the interest rate per period.

n is the total number of payments.

Since contributions are made monthly, the annual interest rate (2% or 0.02) is divided by 12 to get the monthly rate, and the total number of contributions is multiplied by 12 to account for monthly contributions over 30 years.

For an investment of $250 per month at a monthly rate of 0.02/12, over 360 months (30 years), we get:

FV = $250*  rac{(1 + 0.02/12)^{360} - 1}{0.02/12}

Now we calculate the future value:

FV ≈ $250 *  rac{(1 + 0.0016667)^{360} - 1}{0.0016667}

FV ≈ $250 *  rac{(1.0016667)^{360} - 1}{0.0016667}

FV ≈ $250 *  rac{2.0398873 - 1}{0.0016667}

FV ≈ $250 * 623.8469386

FV ≈ $155,961.73

The total amount invested over 30 years is $250 * 12 *30 = $90,000.

The interest earned is therefore:

Interest = FV - Total amount invested

Interest ≈ $155,961.73 - $90,000

Interest ≈ $65,961.73

So the interest earned on the account after 30 years is approximately $65,961.73.

Answer:

2

Step-by-step explanation:

f'(x) is an odd function (symmetrical about the origin), therefore f(x) is an even function (symmetrical about the y-axis).  So f(x) = f(-x).

Since f(-4) = 2, f(4) = 2.

We can also show this using integrals:

f(-4) = ∫₀⁻⁴ f'(x) dx + C

2 = ½ (-4)(-2) + C

2 = 4 + C

C = -2

f(4) = ∫₀⁻⁴ f'(x) dx − 2

f(4) = ½ (4)(2) − 2

f(4) = 4 − 2

f(4) = 2

Answer:

14

Step-by-step explanation:

In mathematics, sum can be defined as the result or answer we get on adding two or more numbers or terms.

(-4)-10=14

The solution to the system of equations is (x, y) = (0, 2).

To solve the system of equations using the elimination method, we'll eliminate one of the variables by adding or subtracting the equations. Let's proceed:

Given the system of equations:

3x - y = -2

-2x + y = 2

We'll add the two equations together to eliminate the variable y:

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

This simplifies to:

3x - y - 2x + y = 0

x = 0

Now, substitute x = 0 into one of the original equations to solve for y. Let's use the first equation:

3(0) - y = -2

-y = -2

y = 2

So, the solution to the system of equations is (x, y) = (0, 2).

Take the number of cups and divide by the number of servings

2 1/4 ÷ 4

Change to an improper fraction

9/4 ÷4

Copy dot flip

9/4 * 1/4

9 /16

Answer: 9/16

Step-by-step explanation: First, take the number of cups and divide by the number of servings. So we have 2 and 1/4 ÷ 4.

Now, rewrite 2 and 1/4 as the improper fraction 9/4 an 4 as 4/1.

So we have 9/4 ÷ 4/1.

Now, dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division sign to multiplication and flip the second fraction. So 9/4 ÷ 4/1 can be rewritten as 9/4 × 1/4.

Now, multiply across the numerators and denominators to get 9/16.

So there are 9/16 cup of raisins in each serving.

Answer:

$120.1355

Step-by-step explanation:

We can model this as an exponencial function:

P = Po * (1+r)^t

Where P is the final value, Po is the inicial value, r is the rate and t is the amount of time.

For this case, we have that Po = 900, r = -25% = -0.25 and t = 7, so we can find the value of P

P = 900 * (1 - 0.25)^7 = $120.1355

The price after 7 years will be $120.1355.

To calculate the value of Dan's computer after 7 years of 25% annual depreciation, we use the exponential decay formula. The approximate value of the computer after 7 years is $120.14.

To calculate the approximate value of Dan's computer after 7 years with a depreciation rate of 25% per year, we can use the formula for exponential decay:

[tex]V = P(1 - r)^t[/tex]

Plugging in the values, we get:

[tex]V = $900(1 - 0.25)^7[/tex]

[tex]V = $900(0.75)^7[/tex]

V = $900 * 0.1334838867

Therefore, the approximate value of the computer after 7 years is:

V = $120.14

Dan can expect the computer to be worth approximately $120.14 after 7 years.

Answer:

Step-by-step explanation:

If the pedestal on which a statue is raised on is a rectangular concrete solid measuring nine  feet long, nine feet wide, and six inches high, the volume of the rectangular concrete solid will be expressed as shown;

Volume of the rectangular concrete solid = Length * Width * Height

Given Length = 9ft, Width = 9ft and Height = 6inches

Converting all the units to yards

Given 1ft = 0.333yard

Length = 9 * 0.333 = 2.997yards

Width = 9* 0.333 = 2.997yards

Also given 1inch = 0.0278yard

Height = 6 * 0.0278yards = 0.1668yards

Volume of rectangular concrete solid in cubic yards = 2.997*2.997*0.1668

Volume of rectangular concrete solid in cubic yards = 1.4982cubic yards

If concrete costs $70 per cubic yard, the cost of the rectangular concrete solid will be 1.4982 *$70 = $104.87

Final answer:

The student's question involves a business math concept of calculating the percent markup from the cost and selling price, resulting in a 50% markup for this example.

Explanation:

The question involves calculating the percent markup based on the cost to store an item and its selling price.

To find the percent of markup, you subtract the cost to store from the selling price and then divide by the cost to store.

Finally, multiply by 100 to get the percentage.

For example, if an item costs $75 to store and sells for $112.50, the markup is ($112.50 - $75) / $75 = 0.50, or 50%.

This is an example of a basic markup calculation commonly covered in business and economics classes in high school.
