All the zeroes of the polynomial x³ - 5x² - 2x + 24 are -2, 3, and 4.

The polynomial can be expressed as [tex]ax^{2} +bx+c=0[/tex], where a, b and c are real numbers. The numbers by which the polynomial expression values equal zero are termed zeroes of the polynomial.

The number of zeroes of the polynomial depends on the highest power of the polynomial.

As x + 2 is one of the factor of f(x),

Now, dividing x³ - 5x² - 2x + 24 by x + 2, we get

Quotient = [tex]x^2-7x+12[/tex]

Remainder = 0

Now, factorizing the quotient by splitting the middle term,

[tex]x^2-3x-4x+12=0[/tex]

[tex]x(x-3)-4(x-3)=0[/tex]

[tex](x-3)(x-4)=0[/tex]

Now, equating both values to 0, we get

x = 3 and x = 4

There are four small lines between 0 and 1 in the number line, they denote the decimals : 0.2, 0.4, 0.6 and 0.8. Put the SUM on the 0.4 line

The percent of data within the interval from 39 to 55 which is normally distributed is 68.26%.

An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the center of the range.

A unique type of normal distribution with a mean of 0 and a standard deviation of 1 is known as the standard normal distribution, or z-distribution. By transforming the values of any normal distribution into z scores, it is possible to standardize it. Z scores provide the number of standard deviations from the mean that each value falls within.

Given in the problem mean is 47 and Standard Deviation(SD) is 8

Probability of data within 39 to 55 is

P(x<55) - P(x<39)

Let Z be the standard deviation :

[tex]\phi(Z) = \frac{x - mean}{SD}[/tex].

for  X = 39

[tex]\phi(Z) = \phi(\frac{x - mean}{SD})[/tex] = [tex]\phi(\frac{39 - 47}{8}) = \phi(-1) = 1 - \phi(1) = 1-.8413 = .1587[/tex]

for X = 55

[tex]\phi(Z) = \phi(\frac{x - mean}{SD})[/tex] = [tex]\phi(\frac{55 - 47}{8}) = \phi(1) = .8413[/tex]

Answer:

i think 2/21 i think im wrong

Step-by-step explanation:

How do I solve for x?

Apply arithmetic operations to both sides of the equation to bring the variable to one side and all other values to the other side in order to find the value of x. To determine the outcome, simplify the values.

Meaning of y = mx + b

The slope-intercept formula for a straight line is y = mx + b. m is referred to as the line’s slope and b is referred to as the line’s y-intercept in the equation y = mx + b for a straight line. Y = mx+b, where

Y ⇒  how far up or down is the line,

X  ⇒ how far along is the line,  

B ⇒ the value of y when x = 0 and

M ⇒ how steep the line is.

This is determined by m = (difference in y coordinates)/ (difference in x coordinates).

1. we have to determine a straight line equation that models the cost of High-Efficiency washing machine over the years;

Slope of the line = change in y / change in x

                            = [tex]\frac{550-525}{2-1}[/tex]

                            = 25

Equation will be

y= 25x+c

Where y is the cost of the High-Efficiency washing machine and x the number of years.

To find c we take points from table,

525= 25×1+ c

c= 525-25

c= 500

Therefore, y= 25x+ 500

2. we have to determine a straight line equation that models the cost of Standard washing machine over the years;

Slope of the line = [tex]\frac{430-400}{2-1}[/tex]

                            = 30

Equation will be,

y= 30x+c

where y is the cost of the Standard washing machine and x the number of years.

To find c we take points from table,

430= 30×1+ c

c= 430-30

c= 400

Therefore, y= 30x+ 400

3. Given the cost functions for both machines over the number of years, we simply equate the two equations and determine the value of x when both machines would cost the same amount;

y= 25x+ 500

y= 30x+ 400

Equating both equations,

30x+ 400= 25x+ 500

30x- 25x= 500-400

5x= 100

x =[tex]\frac{100}{5}[/tex]

x= 20

Therefore, the washing machines would cost the same amount after 20 years of use.

4. To determine which machine would be the more practical purchase if kept for 9 years we use the cost functions obtained in 1. and 2.

High-Efficiency washing machine

y= 25x+ 500

y= 25×9+ 500

y= 725

Standard washing machine

y= 30x+ 400

y= 30×9+ 400

y= 670

Therefore, the cost for the Standard washing machine is more practical.

Answer:

To determine the test statistic for this problem, we need to first calculate the standard error of the mean. This is given by the formula:

Standard error of the mean = Standard deviation / sqrt(n)

where n is the number of samples in the population. In this case, the standard deviation is 1 minute and the number of samples is 20, so the standard error of the mean is equal to 1 / sqrt(20) = 0.22.

We can now use this value to calculate the test statistic, which is given by the formula:

Test statistic = (Sample mean - Population mean) / Standard error of the mean

In this case, the sample mean is 3.7 minutes, the population mean is less than 3.5 minutes, and the standard error of the mean is 0.22. Since the population mean is less than 3.5 minutes, we will use 3.5 as the value for the population mean in our calculation. Plugging these values into the formula, we get:

Test statistic = (3.7 - 3.5) / 0.22 = 0.22 / 0.22 = 1

Therefore, the test statistic for this problem is 1. This value indicates that the sample mean is slightly higher than the population mean, but not by a significant amount.

Answer:

The solutions to the given equations are x = 4, x = -4, x = 3y, x = -3y, 1/5x = 8y, and 1/5x = -8y.

Step-by-step explanation:

These are all algebraic expressions, which are combinations of variables, numbers, and mathematical operations. The first expression, 16 - x^2, is an example of a difference of squares. The second expression, x^2 - 9y^2, is also a difference of squares. The third expression, 1/25x^2 - 64y^2, is a difference of squares with a fractional coefficient in front of the first term.

To solve an equation, we need to find the values of the variables that make the equation true.

For the first equation, 16 - x^2, we can solve it by adding x^2 to both sides to get rid of the negative sign. This gives us 16 = x^2, and then we can take the square root of both sides to get x = +/- 4. Therefore, the solutions to this equation are x = 4 and x = -4.

For the second equation, x^2 - 9y^2, we can solve it by factoring the left-hand side to get (x - 3y)(x + 3y) = 0. This means that the product of the two factors on the left-hand side must be equal to 0, so either x - 3y = 0 or x + 3y = 0. Solving each of these equations separately, we get x = 3y and x = -3y. Therefore, the solutions to this equation are x = 3y and x = -3y.

For the third equation, 1/25x^2 - 64y^2, we can solve it by factoring the left-hand side to get (1/5x - 8y)(1/5x + 8y) = 0. This means that the product of the two factors on the left-hand side must be equal to 0, so either 1/5x - 8y = 0 or 1/5x + 8y = 0. Solving each of these equations separately, we get 1/5x = 8y and 1/5x = -8y. Therefore, the solutions to this equation are 1/5x = 8y and 1/5x = -8y.

In summary, the solutions to the given equations are x = 4, x = -4, x = 3y, x = -3y, 1/5x = 8y, and 1/5x = -8y.

Answer: $5

Step-by-step explanation: To calculate how much she spent on the 4 boxes of candy, we need to subtract 5 from 25, because we won't be including the cost of the magazine. So, therefore 25-5 is 20. So, now to find the cost for one, we need to set up a proportional relationship like this:

[tex]\frac{20}{4}[/tex] = [tex]\frac{?}{1}[/tex]

So, with that, we need to divide 4 by 20 to find the cost of 1. So, if you know, 20 divided by 4 = 5. So, therefore the cost of each candy box is $5. We can check our answer if we use the inverse operations, so our new equation would look like this:

5(4) + 5 = 25

We can check this, because we know 5 x 4 = 20, and 20 + 5 = 25. So 25 = 25, so it is $5.00
