If the interior angles in the octagon is (4x-80)°, (4x-80)°,(2x+50)°,(2x+50)°,(4x-80)°,(4x-80)°,(2x+50)°,(2x+50)° then the value of x is equal to 50.

Given that the interior angles in the octagon is (4x-80)°, (4x-80)°,(2x+50)°,(2x+50)°,(4x-80)°,(4x-80)°,(2x+50)°,(2x+50)°,(4x-80)°.

We are required to find the value of x that are used in the angles of the given octagon.

Octagon is the shape that has eight sides,eight vertices,eight angles. Sum of all the interior angles of octagon is equal to 1080°.

(4x-80)°+ (4x-80)°+(2x+50)°+(2x+50)°+(4x-80)°+(4x-80)°+(2x+50)°+(2x+50)°=1080

24x-120=1080

24x=1080+120

24x=1200

x=1200/24

x=50

Hence if the interior angles in the octagon is (4x-80)°, (4x-80)°,(2x+50)°,(2x+50)°,(4x-80)°,(4x-80)°,(2x+50)°,(2x+50)° then the value of x is equal to 50.

Mr. Price deposited a $10 bill for $50, a $5 bill for $75, and a $1 bill for $45.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

We have been given that the number of $5 bills was 3 times the number of $10 bills

Let the number of $10 bills would be x

As per the given condition,

$10 = x

$5 = 3x

$1 = 3x+30

Since he deposited $170 in his bank.

So 10x + 5(3x) + 1(3x+30) = 170

⇒ 25x+3x+30=170

⇒ 28x=140

⇒ x = 5

Therefore, $10 for $50

So 3x = 15, $5 for $75

So 3x+30 = 45, $1 for $45

Hence, he deposited a $10 bill for $50, a $5 bill for $75, and a $1 bill for $45.

Step-by-step explanation:

The perimeter of the rectangle can be expressed as 10t - 26u centimeters.

Perimeter is the total length of the outer boundary of a two-dimensional shape or a three-dimensional space. It is a measure of the length around the outside of an object or a space and is usually expressed in linear units, such as millimeters, centimeters, meters, or kilometers.

The perimeter of a rectangle is the sum of the lengths of all four sides. Since the width and length of the rectangle are given as (t - 9u) centimeters and (4t - 4u) centimeters, respectively, the perimeter of the rectangle can be expressed as:
Perimeter = 2(t - 9u) + 2(4t - 4u)
Perimeter = 2t - 18u + 8t - 8u
Perimeter = 10t - 26u centimeters

On average, U.S women live more than men in 151,400,000 seconds.

Average:

Average is the ratio of the total value divided by the number of observation  used.

Given,

In 2008, the centers for disease control and prevention reported the average human life span in the united states as 76.8 years for men and 81.6 years for women.

Here we need to calculate how much longer, on average, u.s. women live than men in seconds.

Here we know that,

Average life span for men = 76.8 years

Average life span for women = 81.6 years.

So, the women lived

=> 81.6 - 76.8

=> 4.8 years.

So, the average women lived 4.8 years more than the man.

Now we have to convert it into seconds,

We know that,

1 year = 31,536,000 seconds

So,

=> 4.8 x 31,536,000 seconds

The percentage of money earned from the sale of hot chocolate is 44%.

Ratio expresses the relationship between two or more numbers. It shows  the number of times that one value is contained within other value(s).

Number of large cups bought = (3/8) x 64 = 24

Number of small cups bought = (5/8) x 64 = 40

Total revenue from selling large cups = 24 x 3.99 = $95.76

Total revenue from selling small cups = 40 x 2.99 = $119.60

Total profit = $119.60 + $95.76 = 215.36

The value of 50-cents coins is $21, the value of 10-cents coins is $15 and the value of the 20-cents coins is $14.

Percentage of the number:

Percentage is defined as the a number or ratio that can be expressed as a fraction of 100.

If we have to calculate percent of a number, divide the number by the whole and multiply by 100.

Given,

Roslan had a total of 50$ in 10-cents coins,20- cent coins and 50-cents coins.

The value of his 10- cents coins was 30% of the total value of all his coins.

The value of his 20-cents coins was 28% of the total value of all his coins.

Here we need to find the value of 50-cent coins.

We know that,

Total value = $50

So the value of 10-cent coins

=> 30% × $50 = $15

Then the value of 20-cent coins

=> 28% × $50 = $14

Through the known values of 10-cents and 20-cents we have calculate the value of 50-cents coins as,

=> $50 – $15 – $14 = $21

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign

While graphing inequalities, we have to keep the following things in mind.

For graphing inequalities with two variables, you will have to plot the "equals" line and then, shade the appropriate area. There are three steps:

Write the equation such as "y" is on the left and everything else on the right.

Plot the "y=" line (draw a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade the region above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

If the endpoint is included (i.e., in case of ≤ or ≥) use a closed circle.

If the endpoint is NOT included (i.e., in case of < or >), use an open circle.

Use open circle at either ∞ or -∞.

Draw a line from the endpoint that extends to the right side if the variable is greater than the number.

Draw a line from the endpoint that extends to the left side if the variable is lesser than the number.

The values of x that correspond to the given quadratic equation ax² + bx + c = 0 are known as its roots.

For, the given expression;

x² + px + q = 0.      ....... (equation 1)

where p and q are constants, has roots -3 and 5.

Part 1: solve for p and q.

Put x = -3 in equation 1.

p(-3) = (-3)² + p(-3) + q = 0

9 - 3p + q = 0         .........(equation 2)

Now, put x = 5 in equation 1.

p(5) = (5)² + p(5) + q = 0

25 + 5p + q = 0     ..........(equation 2)

Solve equation 2 and 3 by elimination method.

p = -2 and q = -15.

Part 2: Estimate the constant r.

The equation is; x² + px + q + r = 0.

Substitute the values of p = -2 and q = -15.

x² + (-2)x + (-15) + r = 0.

As, the equation given real equal roots; then,

discriminant value: b² - 4ac = 0.

Substitute the values;

(-2)² - 4×1×(-15 + r) = 0

We are given the vertex of the square as (2, 3).

Now, it is well known that the sides of a square are equal.

This means that there must be another vertex that will have 3 as its' y-coordinate. Similarly, there will be a different coordinate that will have its' x-coordinate as 2.

Similarly, another 2 points will be reflected over the y-axis to get a negative of the previous two x-values. This also applies to the y-values. Thus, when we combine all these together, we will have the coordinates as; (2, 3), (-3, 3), (-3, -2) and (2, -2)

A sequence in which the ratio of any term and its previous term is equal to a fixed constant called common ratio [r] is called geometric progression. For example -

3, 6, 12, 24, ... and so on.

Given that Quinten shares a secret with his friend and each person that hears the secret shares the secret with a new person each day.

On the first day only 2 people know the secret i.e. Quinten and his close friend. Now, they both will tell one new person on second day, which means that by the end of second day four persons will know the secret. Now, these four persons will share with new individual, this gives us a total of 8 persons, who knows the secret by the end of day three and so on.

Now, we get the following sequence -

2, 4, 8, ...... and on.

Now, we can clearly see that -

4/2 = 8/4 = 2

Therefore, this sequence is a geometric progression with common ratio

r = 2.

If the chi-square value is going on English the likelihood of rejecting the null hypothesis also increases because there is a chance that the chi-square value increases more than the significant value that is given in the question. So the required answer is that increases as the required answer.

For example, if, according to Mendel's laws, you expected 10 of 20 offspring from a cross to be male and the actual observed number was 8 males, then you might want to know about the "goodness to fit" between the observed and expected.

Were the deviations (differences between observed and expected) the result of chance, or were they due to other factors? How much deviation can occur before you, the investigator must conclude that something other than chance is at work, causing the observed to differ from the expected.

The chi-square test is always testing what scientists call the null hypothesis, which states that there is no significant difference between the expected and observed result.
