whats 6 1/3 as an inpoper fraction

Answer:

{14, 47, 50}

Step-by-step explanation:

The three sides of a right triangle must satisfy

a² + b² = c², known as the Pythagorean Theorem. So let's put the pairs into the theorem.

20, 48, 52

a² + b² = c²

20² + 48² = 52²

400 + 2304 = 2704

2704 = 2704

20, 48, and 52 represent the three sides of a right triangle.

40, 75, 85

a² + b² = c²

40² + 75² = 85²

1600 + 5625 = 7225

7225 = 7225

40, 75, and 85 represent the three sides of a right triangle.

14, 47, 50

a² + b² = c²

14² + 47² = 50²

196 + 2209 = 2500

2405 ≠ 2500

14, 47, and 50 do NOT represent the three sides of a right triangle.

13, 84, 85

a² + b² = c²

13² + 84² = 85²

169 + 7056 = 7225

7225 = 7225

13, 84, and 85 represent the sides of a right triangle.

14, 47, and 50 do NOT represent the three sides of a right triangle, therefore making it your answer.

Answer:

  a) 300000

  b) £200

  c) 20000 km

Step-by-step explanation:

You always start counting significant digits starting with the left-most non-zero digit in the number. If there is no decimal point, the right-most non-zero digit is the last of the significant digits. If there is a decimal point, the right-most digit is the last of the significant digits.

The number 276040 in part (a) has 5 significant digits: 2, 7, 6, 0, 4.

__

We want numbers with only 1 significant digit. That means we keep only the left-most non-zero digit, rounding up if necessary.

a) 276040 ⇒ 300000

b) £238.02 ⇒ £200

c) 17521 km ⇒ 20000 km

_____

Additional comment

In part (b), we dropped the decimal point and the fractional part because we want the count of significant digits to stop with the first one.

The final simplified expression is: -211/7i - 3/7

To simplify the given expression, let's work step by step:

(4 - i)(-3/7i) - 7i(8/2i)

First, let's simplify each multiplication:

(4 * -3/7i - i * -3/7i) - (7i * 8/2i)

Now, simplify further:

(-12/7i + 3/7i^2) - (56/2)

Remember that i^2 is equal to -1:

(-12/7i + 3/7(-1)) - (28)

Simplify the expression:

(-12/7i - 3/7) - 28

Combining like terms:

-12/7i - 3/7 - 28

Now, let's express the terms as a single fraction:

-12/7i - 3/7 - 196/7

Combine the numerators:

(-12 - 3 - 196)/7i - 3/7

Simplify further:

(-211)/7i - 3/7

The final simplified expression is:

-211/7i - 3/7

To find a value of c such that P(z ≥ c) = 0.55, we need to use a standard normal distribution table or calculator.From the standard normal distribution table, we find that the z-score corresponding to a right-tailed area of 0.55 is approximately 0.126.

Therefore, we have:

P(z ≥ c) = 0.55

P(z ≤ c) = 1 - P(z ≥ c) = 1 - 0.55 = 0.45

Using the standard normal distribution table, we find that the z-score corresponding to a left-tailed area of 0.45 is approximately -0.126.

So, c = -0.126.

Therefore, the value of c that satisfies P(z ≥ c) = 0.55 is approximately -0.126.

The solution to the integral is:\(∫ 1/(sinh(x)) dx = (1/2) ln|sinh(x) + sinh(x)^2| + C.\)

To find the integral of \(1/(sinh(x))\), we can use the substitution \(u = sinh(x)\), which implies\(du/dx = cosh(x)\) and\(dx = du/cosh(x)\). Substituting these into the integral, we get:

\(∫ 1/(sinh(x)) dx = ∫ 1/u * du/cosh(x)\)

\(= ∫ cosh(x)/u * du\)

Now, we can use the identity\(cosh^2(x) - sinh^2(x) = 1\)to replace\(cosh(x)^2\)with \((sinh(x)^2 + 1)\)in the integrand:

\(∫ (sinh(x)^2 + 1)/u * du\)

\(= ∫ sinh(x)^2/u * du + ∫ 1/u * du\)

The first integral can be rewritten using the identity \(sinh^2(x) = (cosh(2x) - 1)/2:\)

\(∫ (cosh(2x) - 1)/(2u) * du\)

\(= (1/2)∫ cosh(2x)/u * du - (1/2)∫ du/u\)

\(= (1/2) ln|u + sinh(x)| - (1/2) ln|u| + C\)

\(= (1/2) ln|sinh(x) + sinh(x)^2| + C\)

Therefore, the solution to the integral is:

\(∫ 1/(sinh(x)) dx = (1/2) ln|sinh(x) + sinh(x)^2| + C\)

In words, this means that the antiderivative of \(1/(sinh(x))\)is equal to one-half times the natural logarithm of the sum of\(sinh(x)\) and \(sinh(x)^2\), plus a constant of integration.

The dimensions are 24 by 13.5 cm

The given parameters are

Length = 3 cm less than twice the width

This means that

L = 2W - 3

Where

L represents Length and W represents Width

The perimeter is given as

P = 75 cm

The perimeter is calculated as

P = 2*(L + W)

So, we have

2*(L + W) = 75

This gives

2*(2W - 3 + W) = 75

Evaluate

2*(3W - 3) = 75

Divide by 2

3W - 3 = 37.5

So, we have

3W = 40.5

Divide by 3

W = 13.5

Recall that

L = 2W - 3

So, we have

L = 2 * 13.5 - 3

Evaluate

L = 24

Hence, the dimensions of the rectangle are 24 by 13.5 cm

They are the set of numbers and symbols that are related by the different mathematical operation signs such as addition, subtraction, multiplication, and division among others.

To solve this problem we must perform the following algebraic operations with the given information

Calculate the days from 08/21/2019 to 08/21/2022, we get:

Days 1 = (08/21/2022 - 08/21/2019) * (365 days/1 year)

Days 1 = 3 years * (365 days/1 year)

Days 1 = 1095 days

Calculate the days from 05/21/2019 to 08/21/2019, we get:

Days 2 = (08/21/2019 - 05/21/2019) * (30 days / 1 month)

Days 2 = 3 months * (30 days / 1 month)

Days 2 = 90 days

Calculating the days from 05/20/2019 to 05/21/2019, we get:

Days 3 = 05/21/2019 - 05/20/2019

Days 3 = 1 day

Calculate the total days from 08/21/2019 to 05/20/2022, we get:

Total days = Days 1 - days 2 - days 3

Total days = 1095 days - 90 days - 1 day

Total days = 1004 days

A relation may or may not represent a function.

The relation that is a function is (c) {(2,3), (3,4), (5,1), (6,2), (7,3)}

For a relation to be considered a function, then the x values must point to different y-values.

The above condition is true for the relation (3).

This is so because all x values in this relation point to different y-values.

(A) The interquartile range for numbers of employees at Mall A is 65 and at Mall B is 7.5. (B) Mall B would we expect to have greater variability in regard to numbers of employees.

Part A: To determine the interquartile range (IQR) for numbers of employees at each mall, we first need to find the median for each mall. The median is the middle value of a set of data when arranged in order.

For Mall A:

Arrange the numbers in ascending order: 18, 20, 21, 22, 25, 26, 27, 28, 28, 29

The median is the average of the two middle numbers, which are 25 and 26.

Median = (25 + 26) / 2

             = 25.5

Next, we need to find the first quartile (Q1) and the third quartile (Q3). The first quartile is the median of the lower half of the data, and the third quartile is the median of the upper half of the data.

For Mall A:

Lower half: 18, 20, 21, 22, 25

Upper half: 26, 27, 28, 28, 29

Q₁ = median of the lower half

    = (21 + 22) / 2

    = 21.5

Q₃ = median of the upper half

     = (28 + 28) / 2

     = 28

The interquartile range for Mall A is:

IQR = Q3 - Q1

      = 28 - 21.5

      = 6.5

For Mall B:

Arrange the numbers in ascending order: 19, 21, 23, 24, 25, 26, 27, 29, 30, 33

The median is the average of the two middle numbers, which are 25 and 26.

Median = (25 + 26) / 2

             = 25.5

Lower half: 19, 21, 23, 24, 25

Upper half: 26, 27, 29, 30, 33

Q₁ = median of the lower half

    = (21 + 23) / 2

    = 22

Q3 = median of the upper half

     = (29 + 30) / 2

     = 29.5

The interquartile range for Mall B is:

IQR = Q3 - Q1

      = 29.5 - 22

      = 7.5

Part B: To determine which mall would have greater variability in regard to numbers of employees, we can compare the interquartile ranges for each mall. The interquartile range measures the spread of the middle 50% of the data. The larger the interquartile range, the greater the variability.

In this case, Mall B has a larger interquartile range than Mall A (7.5 vs. 6.5). This suggests that there is greater variability in the number of employees at Mall B.

You have two ways to pay for your new dishwasher: either you can make a single payment of $400 immediately, or you can make six payments of $70, the first of which must be done today. The second option's EAIR is 6.54%.

Here are the steps on how to calculate the effective annual interest rate (EAIR) of the second option using Excel:

In Excel, create a new spreadsheet and enter the following information:

Present Value: $400

Number of payments: 6

Amount of each payment: $70

Use the FV function to calculate the future value of the annuity. The FV function takes the following arguments:

Present Value

Number of periods

Interest rate per period

Compounding frequency

In this case, the interest rate per period is equal to the monthly interest rate, which we need to calculate first.

Calculate the monthly interest rate. The monthly interest rate is equal to the annual interest rate divided by 12. In this case, the annual interest rate is 6%, so the monthly interest rate is 0.5%.

Set the compounding frequency to monthly.

The FV function will return the future value of the annuity, which is $426.18.

The EAIR is equal to the difference between the future value and the present value, divided by the present value, and multiplied by 100%. In this case, the EAIR is equal to 6.54%.

Here is the formula for calculating the EAIR:

\(\begin{equation}\text{EAIR} = \frac{\text{FV} - \text{PV}}{\text{PV}} \times 100\%\end{equation}\)

Here is the output of the FV function:

=FV(400,6,0.005,12)

Output:

426.18

Here is the formula for calculating the EAIR:

\(\begin{equation}(426.18 - 400) / 400 * 100\%\)

Output:

6.54%

Therefore, the EAIR of the second option is 6.54%.

Answer:

Molly earned $856 on the first day.

Step-by-step explanation:

From the information given, you know that over 3 days Molly earned $2,568 which is:

x+y+z=2568, where:

x is the amount earned on the first day

y is the amount earned on the second day

z is the amount earned on the third day

Also, you know that she earns twice as much money on the first day then the second day, which is: x=2y and that she earns 3 times as much money than the second day on the 3rd day, which is: z=3y.

Now you can replace x and y in the first equation and solve for y:

2y+y+3y=2568

6y=2568

y=2568/6

y=428

No, you can replace the value of y to find x and z:

x=2(428)

x=856

z=3(428)

z=1284

According to this, the answer is that Molly earned $856 on the first day.
