The graph of f has inflection points when x = 0 and -1.
Given that,
If graph = f"(x) = x(x + 1)(x - 2)^2
We have to determine,
The graph of f has inflection point when x is.
According to the question,
Inflection point is the point in which the rate of slope changes in increasing to decreasing order or vice versa.
These points are generally not local maxima or minima but stationary points.
[tex]f''(x) = 0[/tex]
Therefore,
The graph of f has inflection point at,
[tex]f''(x) = x (x+1) (x-2)^{2} = 0\\\\x = 0 \ and \ x+1 = 0 \ \ = x = -1\\\\ or \ x-2 = 0 , \\\ \ \ = x =2[/tex]
On taking intersection of these points,
The graph has inflection points at x = 0 and -1.
Hence, The graph of f has inflection points when x = 0 and -1.

The Empirical Rule says that: Group of answer choices outliers are within three standard deviations of the mean. about 32 percent of the data are beyond one standard deviation from the mean most business data sets are normally distributed in most business data we expect the mean and median to be similar.
Answer:
The Empirical Rule says that:
outliers are within three standard deviations of the mean.
Step-by-step explanation:
An outlier is an observed data value which lies some abnormal distance from other values in a population's random sample. The cut-off for an outlier is three standard deviations from the mean in a normal distribution. Therefore, the Empirical Rule concludes that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean. In summary, the empirical rule concludes that 68% of the data falls within one standard deviation, 95% percent falls within two standard deviations, while 99.7% falls within three standard deviations from the mean.
Which inequality describes all the solutions to -5x + 6 < 2(-3 − x)?
Answer: x>4
Step-by-step explanation:
The solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.
The given inequality is 5x + 6 < 2(-3 - x).
What is a inequality?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.
The given inequality can solved as follows:
5x + 6 < 2(-3 - x)
Multiply 2 to the bracket
5x + 6 < -6 - 2x
Add 2x to both the sides of inequality
5x + 6 + 2x < -6 - 2x + 2x
⇒7x+6<-6
Subtract 6 to both the sides of inequality
7x+6-6<-6-6
⇒7x<-12
Divide 7 to both the sides of inequality
7x/7<-12/7
⇒x<-12/7
⇒x<-1.7
Solution set = {-2, -3, -4, -5, -6,.......}
Therefore, the solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.

Work out the size of angle x.
47°
Answer:
133 degrees
Step-by-step explanation:
The angle 47 degrees is on a straight line, and the angles on a straight line add up to 180 degrees.
So, to find the angle parallel to 47 degrees, subtract 47 degrees from 180 degrees
180 - 47 = 133 degrees
Now, the relationship between the angle that is 133 degrees and the angle of x is that they are corresponding angles.
And corresponding anglea are the same.
Thereforw, x = 133 degrees

Consider all seven-digit numbers that can be created from the digits 0-9 where the first and last digits must be even and no digit can repeat. Assume that numbers can start with 0. What is the probability of choosing a random number that starts with 4 from this group
Answer:
[tex]P_4= 0.2[/tex]
Step-by-step explanation:
From the question we are told that
Consider all seven-digit numbers
Created from the digits 0-9
Generally number of digits that starts with 6 is mathematically given as
The total amount of digits from 0-9(0,1,2,3,4,5,6,7,8,9 = 10
The total amount of even digits within 0-9 (0,2,4,6,8) = 5
The total amount of 3-digit numbers giving the first and last digits to be even = 5 * 10 * 5 = 250
The total 3-digit numbers giving the first digit is 4 and last digit is even = 1 * 10 * 5 = 50
Probability the number starts with 4
[tex]P_4 = \frac{50}{250}[/tex]
[tex]P_4= 0.2[/tex]

A survey was distributed to 2.000 employees and 90 percent of these employees responded to the survey. Of the employees responding, 60 percent answered "yes" to a certain yes-no question and 72 employees did not answer that question. How many employees answered "no" to this question?
Answer:
720 employees
Step-by-step explanation:
Number of responded employees = 90% of 2000 employees = 1800 employees
Out of 1800 employees, if 60% answer yes, then the remaining 40% will answer "no". 72 employees did not respond to the survey.
Number of "no" answered employees = 40% of 1,800 employees = 720 employees( Answer)

Answer:
(Note: This is assuming that the answer can be in any format.)
[tex]y - 0 = -\frac{1}{3} (x - 3)[/tex]
Step-by-step explanation:
When given at least two points, you can find write an equation using the point-slope formula: [tex]y - y_1 = m (x - x_1)[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] are the x and y values from one point that need to be substituted in to make an equation, as well as the [tex]m[/tex] which represents the slope.
Find the slope by using the slope formula [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] and the two points given:
[tex]\frac{-1-0}{6-3}[/tex]
[tex]\frac{-1}{3}[/tex]
So, the slope is [tex]-\frac{1}{3}[/tex].
Next, choose a point (in this case, I chose (3,0)) and substitute its x and y values into [tex]x_1[/tex] and [tex]y_1[/tex] respectively, and also substitute [tex]-\frac{1}{3}[/tex] for m. This forms an equation of a line in point-slope formula:
[tex]y - 0 = -\frac{1}{3} (x - 3)[/tex]
