Donna finished 67% of her homework. What fraction of her homework is completed?

Answer:

Step-by-step explanation:

To differentiate the function y = x^4 - x, we will use the power rule of differentiation. The power rule states that if f(x) = x^n, then the derivative of f(x) is f'(x) = nx^(n-1).

So, for y = x^4 - x, we can find the derivative as follows:

y' = 4x^3 - 1

So, the derivative of the function y = x^4 - x is y' = 4x^3 - 1.

As a result of answering the given question, we may state that As a result, after 6 years, the bond will earn $192 in interest.

Divide the principal by the interest rate, period, and other factors to get simple interest. The formula in marketing is simple: return = principal + interest + hours. This method makes it easiest to calculate interest. Interest is frequently expressed as a percentage of the main balance. He will only pay half of the entire interest if he borrows $100 from a friend and agrees to repay it with 5% interest. $100 (0.05) = $5. You must pay interest when you borrow money, and you must charge interest when you lend it. Interest is often calculated as an annual percentage of the loan balance. This proportion is known as the loan's interest.  

To compute simple interest, use the following formula:

The interest rate = (Principal x Rate x Time)

where:

The principal is the bond's initial amount, which is $800 in this example.

The annual interest rate is 4%, or 0.04 in decimal form.

Time is the number of years, which in this case is six.

When we enter these values into the formula, we get:

(800 x 0.04 x 6) = $192 in interest

As a result, after 6 years, the bond will earn $192 in interest.

Given :

Work done by a segment dx of a cable :

dW = 8dx x = 8x dx

So, work done by whole cable :

\(W=\int\limits^{450}_0 {8x} \, dx\\\\W = 4x^2|_0^{450}\\\\W = 4( 450^2)\\\\W= 810000\ ft- lb\)

Now, work done to bring coal up :

\(W'=900\times 450\ ft-lb\\\\W'=405000\ ft-lb\)

Therefore, total work done is ( 810000 + 405000 ) = 1215000 ft-lb .

Hence, this is the required solution.

The new price of the car is $25441.

Given that the $26,000 car is on sale for 5% off with 3% tax.

The discount will be:

= 5% × $26000

= $1300

The tax will be:

= 3% × ($26000 - $1300)

= 3% × $24700

= $741

The new price will be:

= Amount - Discount + Tax

= $26000 - $1300 + $741

= $25441

Therefore , the solution of the given problem of fraction comes out to be Jada shaded 3/4 of the paper.

An whole can be represented by any set of related sums or fractions. In standard English, a percentage is used to represent the quantity of a specific size. 8, 3/4. Also wholes are fractions. Numbers are expressed in mathematics using the ratio of it's own portion to the bottom. These fractions are all made up of basic numbers. Due to variances in actual percentage calculations, numerators, and numerators, a difficult fraction contains a fraction. .

Here,

Based on the picture, it looks like Jada folded the paper in half vertically and horizontally, resulting in four equal quadrants.

She shaded three of these quadrants, leaving one unshaded.

Each shaded quadrant is half of a half, or 1/4, of the total paper.

Therefore, Jada shaded 3/4 of the paper.

The percent of the bags of chips weigh less than 176 grams is b 16%

From the question, we have the following parameters that can be used in our computation:

Mean = 180

Standard deviation = 4

Bags of chips weigh less than 176 grams

This means that

x = 176

So, the z-score is

z = (176 - 180)/4

Evaluate

z = -1

The percent of the bags of chips weigh less than 176 grams is represented as

P = P(z < -1)

Using a graphing calculator, we have

Percentage = 0.15866

So, we have

Percentage = 16%

Hence , the percentage is 16%

Step-by-step explanation:

Scientific notation

To figure out the power of 10 think "how many places do I move the decimal point?"

When the number is 10 or greater the decimal point moves to the left, and the power of 10 is positive.

When the number is smaller than 1 the decimal point moves to the right, so the power of 10 is negative.

Answer:

bag B

Step-by-step explanation:

bag A: 5R and 2G

bag B: 7R and 3G

Bag A probability for green is 2/7

bag B probability for green is 3/10

if we convert the fractions to have a common denominator:

bag A: 20/70

bag B: 21/70

so bag B has the greater probability of drawing a green marble

Answer:

no solutions

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

equation of blue line is y = x + 2 , in slope- intercept form

with slope m = 1

equation of red line is y = x - 3 , in slope- intercept form

with slope m = 1

• Parallel lines have equal slopes

then the blue and red lines are parallel.

the solution to the system is at the point of intersection of the 2 lines

since the lines are parallel then they do not intersect each other.

thus the system shown has no solution.

Answer:

(1) Ordinal

(2) Such data should not be used for calculations such as an average.

Step-by-step explanation:

Given

\(2 \to Medium\)

\(3 \to High\)

\(Average = 1.3\)

Solving (a): The level of measurement

When observations are presented in ranks such as:

\(1 \to Low\)

\(2 \to Medium\)

\(3 \to High\)

The level of measurement of such observation is ordinal

Solving (b): What is wrong with the computation?

Ordinal level of measurement are not numerical values whose average can be calculated because they are used as ranks.

The solution of the given quadratic equation -5 = -36 / m + m is,

 m = - 9 or  m = 4

The given equation is

-5 = -36 / m + m

After re arranging it we get,

m² + 5m - 36 = 0

This is nothing but quadratic equation,

Since we know that,

The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations. The quadratic equation has the following generic form:

ax² + bx + c = 0

So now we can write,

⇒ m² + 9m - 4m - 36 = 0

⇒ m(m + 9) - 4(m + 9) = 0

⇒ (m + 9)(m - 4) = 0

Therefore,

⇒ (m + 9) = 0 or (m - 4) = 0

⇒ m = - 9 or  m = 4

Thus,

The solution of the given expression is

m = - 9 or  m = 4

What is fractional equivalent?

Equivalent fractions are fractions with distinct numerators and denominators but the same value.

1. The number represented by n has two repeating digits, 15.

2. To convert the repeating decimal to a fraction, we need to identify the place value of the repeating digits. In this case, the repeating digits start immediately after the decimal point, so we need to multiply by a power of 10 that is equal to the number of repeating digits, which is 2.

3. Power of 10 times n = 10^2 x 0.1515... = 15.15...

        \(0.1515... x 10^2 = 15.15...\\\\\)

4.

       \(10^2n = 15.15...\\\\n = 0.1515...\\\\99n = 15\)

To obtain the equation, we multiplied the original bby 100 to eliminate the decimal, which gives 100n = 15.1515... We then subtracted the original equation from the multiplied equation to eliminate the repeating digits, which gives 99n = 15.

5. 99n = 15

n = 15/99

To obtain the fraction, we divided both sides of the equation by 99.

Therefore, the fractional equivalent of the repeating decimal n = 0.1515... is 15/99, which can be simplified to 5/33 in simplest form.
