The sum will be close to 1/2

Step-by-step explanation:

1/4+2/7=15/28

The common denominator of 1/4 and 2/7 is 28.

1/4 -> 7/28

2/7 -> 8/28

7/28+8/28=15/28

turn that into a decimal and it will round to 0.5257

1/2=0.5

so the answer will be closer to 1/2

The remainder of the given equation:

Long-division polynomials are algorithms that divide polynomials by polynomials of the same or lower degree. As with the long division method of numbers, the divisor, quotient, dividend, and remainder are all part of the long division of polynomials.

When a divisor has more than one term or is a polynomial with more than one term, the four stages used to divide whole numbers (divide, multiply, subtract, bring down the next term) comprise the repeated operation for polynomial long division.

(4x² – 11x³ – 13x² +96x+52) ÷ (4x + 9) given.

Simplifying the equation:

(4x² – 11x³ – 13x² +96x+52)

(-11x³ - 9x² + 96x + 52)

Applying Polynomial long division:

(-11x³ - 9x² + 96x + 52)÷ (4x + 9)

If the ratio of cars to truck in a parking lot is 5:3 and the total number of cars is 30, then the total number of truck in the parking lot is 18

Given,

The ratio of cars to truck in the parking lot = 5:3

Total number of cars in the parking lot =30

Then, the equation will be

5x=30

x=6

Then,  the number of tucks in the parking lot =3x

3×6=18

Hence, if the ratio of cars to truck in a parking lot is 5:3 and the total number of cars is 30, then the total number of truck in the parking lot is 18

Answer:

x = 50°

Step-by-step explanation:

draw a line through B parallel to the 2 given parallel lines , then

the upper angle at B and 150° are same- side interior angles and sum to 180°

upper angle = 180° - 150° = 30°

the lower angle at B and 160° are same- side interior angles and sum to 180°

lower angle = 180° - 160° = 20°

Then

x = upper angle + lower angle = 30° + 20° = 50°

This problem is associated with linear equations. The total price will be 1.07x dollars.

There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.

Given,

Leila is buying a replica of a dinosaur.

The model is priced at x dollars, plus she must pay a 7% tax.

7% is shown in decimal form.

= 0.07

Tax price = 0.07 times the model's cost

= 0.07x

Total cost Leila pays for the model by adding the tax price to the model's cost.

Combining the values in the aforementioned

Leila pays the model a total of 0.07x + x.

= 1.07 in currency

As a result, Leila pays a total of 1.07 for the model.

Answer:

y = [tex]\frac{1}{2}[/tex] x - 2

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 )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (6, 1 ) and (x₂, y₂ ) = (- 6, - 5 )

m = [tex]\frac{-5-1}{-6-6}[/tex] = [tex]\frac{-6}{-12}[/tex] = [tex]\frac{1}{2}[/tex] , then

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (6, 1 )

1 = 3 + c ⇒ c = 1 - 3 = - 2

y = [tex]\frac{1}{2}[/tex] x - 2 ← equation of line

The technique that most clearly minimizes the likelihood that any outcome differences between the experimental and control groups is e. random assignment.

A methodology used to divide research participants into two groups—the treatment group, also known as the experimental group, and the control group—by randomization is known as random assignment, also known as random placement.

Every research volunteer has an equal chance of being assigned to any of the groups thanks to this randomization mechanism.

In studies, random assignment is a method used to divide participants into different research groups with similar characteristics so that the groups are equal at the start of the investigation.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 247, \sigma = 60[/tex]

For item a, the proportion is the p-value of Z when X = 167, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (167 - 247)/60

Z = -1.33.

Z = -1.33 has a p-value of 0.0918.

Hence the percentage is of 9.18%.

For item b, the proportion is the p-value of Z when X = 367, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (367 - 247)/60

Z = 2.

Z = 2 has a p-value of 0.9772.

Hence the percentage is of 97.72%.

For item c, the proportion is one subtracted by the p-value of Z when X = 247, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (247 - 247)/60

Z = 0.

Z = 0 has a p-value of 0.5.

1 - 0.5 = 0.5.

Hence the percentage is of 50%.

For item d, the proportion is one subtracted by the p-value of Z when X = 350, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (350 - 247)/60

Z = 1.72

Z = 1.72 has a p-value of 0.9573.

1 - 0.9573 = 0.0427.

Hence the percentage is of 4.27%.

For item e, the proportion is the p-value of Z when X = 67, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (67 - 247)/60

Z = -3.

Z = -3 has a p-value of 0.0013.

Hence the percentage is of 0.13%.

For item f, the proportion is the p-value of Z when X = 300 subtracted by the p-value of Z when X = 200, hence:

X = 300:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (300 - 247)/60

Z = 0.88.

Z = 0.88 has a p-value of 0.8106.

X = 200:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (200 - 247)/60

Z = -0.78.

Z = -0.78 has a p-value of 0.2177.

0.8106 - 0.2177 = 0.5929.

Hence the percentage is of 59.29%.

For item g, the proportion is the p-value of Z when X = 400 subtracted by the p-value of Z when X = 360, hence:

X = 400:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (400 - 247)/60

Z = 2.55.

Z = 2.55 has a p-value of 0.9946.

X = 360:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (360 - 247)/60

Z = 1.88.

Z = 1.88 has a p-value of 0.97.

0.9946 - 0.97 = 0.0246.

Hence the percentage is of 2.46%.

For items h and i, the distribution is symmetric and the mean and the median are equal, hence both percentages are 50%.
