What’s the correct answer answer asap

Answer:

b. 12.6

Step-by-step explanation:

Calculated using the Pythagorean theorem:

we need the height and base of the cone,

the radius of the cone can be found by calculate half of the diameter which is: 8 ÷ 2 = 4

4² + 12² = x²

which is:

16 + 144 = x²

is equal to:

160 = x²

We find the square root of 160, which is:

An expression which has a coefficient of 6 and a constant of 9 include the following: C. 6x + 9.

In Mathematics, an algebraic expression can be defined as a type of mathematical equation which is typically used for showing the relationship existing between two (2) or more variables, numerical quantities (constants), accompanied with the use of different mathematical operations.

In Mathematics, a coefficient can be defined as a constant quantity, numerical data, or numerical value (number or numeral) that is typically placed before the variable in an algebraic expression.

Assuming the variable is x, an algebraic expression that has a coefficient of 6 and a constant of 9 would be written as follows;

Algebraic expression = (coefficient × x) + constant

Using data points, the value of correlation coefficient is obtained which expresses the link between two variables.

The correlation coefficient, which is used in correlation methods, captures the link between two variables in a single value. The correlation coefficient spans from -1 to +1 and is typically denoted by the letter r.

In order to find correlation using data points, the following steps are required to be followed.

Step 1: We need to determine the data sets.

We need to determine our variables and the data sets whose values can be placed in our equation. We need to separate these values by x and y variables.

Step 2: We need to calculate the standardized value for x variables.

After determining the data sets, the following equation is used to calculate a standardized value for every x(i) variable:

(z(x))(i) = (x(i) - x‌) / s(x)

where,

(x(i), y(i)) is a pair of data

x‌ is the mean of x(i)

ȳ is the mean of y(i)

s(x) is the standard deviation of x(i)

s(y) is the standard deviation of y(i)

Step 3: We need to calculate the standardized value for y variables.

After determining the standardized value for every x(i), we need to repeat it for calculating each y(i) with the following equation:

(z(y))(i) = (y(i) - ȳ) / s(y)

Step 4: We need to multiply and find the sum.

After obtaining the standardized values, we need to multiply them together. After multiplying the values, we need to add them together for finding the sum.

Step 5: We need to divide the sum and determine the correlation coefficient.

In the last step, we will use n to represent the total number of points in the data pair. Then, we will divide the sum obtained in step four by n-1. This way we will obtain the correlation coefficient.

Hence, the correlation coefficient is obtained using the data points.

Answer:

If the price was decreased by 15% and the price became $2176, the original price would be:

$2176 / (1 - 0.15) = $2176 / 0.85 = $2560

If we first increase the price by 10% and then decrease it by 25% we can use the following method:

Multiply the original price by 110% to increase it by 10%: $2560 * 1.1 = $2816

Multiply the increased price by 75% to decrease it by 25%: $2816 * 0.75 = $2,112

So the price would be $2,112 if the price was increased by 10% first, and then decreased by 25%.

The variable x has infinite many solutions in the expression 10x - 3 + 2x + 4

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

10x - 3 + 2x + 4

The given parameter above is an expression, not an equation

This means that we cannot determine the value of x

This is so because the variable x has infinite many solutions

This in other words means that the variable x can assume any value, and the expression would assume any value depending on the value of x

Hence, the variable x cannot be determined or it has infinite many solutions

The expected number of shots required to knock all of the targets down is 1/p.

The expected number of shots required to knock all of the targets down is equal to 1 divided by the probability of hitting a target (p). This is because the probability of hitting a target on any given shot is p, and so the expected number of shots required to knock all of the targets down is the inverse of that probability.

The length of PK is half of the circle chord JK and is equal to 22.

We shall first find the value of x by equating JK to LM as PQ is similar to QR, then we divide the circle chord with length JK to get PK as the radius forms an angle 90° with Jk.

9x - 19 = 3x + 23

9x - 3x = 23 + 19

6x = 42

x = 42/6

x = 7

JK = 3(7) + 23 = 44

The new price of the table, given the original price of the oak table and the increase in price, is £ 441

The new price of the table would be higher than the original price because the price of the oak table is said to have risen by up to 47 %. This means that whatever the price of the oak table was, it would now be 47 % higher.

The price of the oak table for Simon can be found by the formula :

= Original price of the oak table x ( 1 + rate of increase )

Original price = £300 .

Rate of increase = 47 %

The new price is :

The equation of the polynomial function is P(x) = (x- 10)(x² + 10x + 21)

The given parameters are

Leading coefficient, a = 1

Zeros = 5, -2 + 2i

There are complex numbers in the above zeros

So, the other zeros are

Zeros = -2 - 2i

The equation of the polynomial is then calculated as

P(x) = Leading coefficient * (x - zero)^multiplicity

So, we have

P(x) = 1 * (x - 5) * (x - (-2 + 2i)) * (x - (-2 - 2i))

This gives

P(x) = 1 * (x- 10) * ((x + 5)² - 4)

So, we have

P(x) = 1 * (x- 10) * (x² + 10x + 25 - 4)

Evaluate the products and the difference

Using the slope-intercept general form of y = mx + c , Parallel lines have same slope and (0,2) gives c = 2 , The answer is y=3x/4 + 2.

An equation is a statement of equality between two expressions. It typically includes numbers and mathematical operations such as addition, subtraction, multiplication, and division. For example, the equation 2x + 3 = 7 is a statement that the value of the expression 2x + 3 is equal to the value of 7. Equations can also include variables, which represent unknown values that can be solved for.

In a linear equation, the slope (also called the gradient) is a measure of the steepness of the line, and the y-intercept is the point at which the line crosses the y-axis. The slope of a linear equation can be represented as m in the form of y = mx + b, where m is the coefficient of x, and b is y-intercept. The y-intercept is the point where the line crosses the y-axis, which can be represented by the value of b in the form of y = mx + b.
