Answer: f(-x) = x^4 -3x^2 +x^6
-f(x) = -x^4 +3x^2 - x^6
Step-by-step explanation:
at f(-x), place a negative sign inside the function of x itself:
f(-x)= (-x)^4 -3(-x)^2 +(-x)^6
because the powers are even, they cancel out.
−3x>24 solve the inequality
Answer:
x < -8
Step-by-step explanation:
−3x>24
Divide each side by negative 3, remembering to flip the inequality
-3x/-3 < 24/-3
x < -8
Answer:
x<-8
Step-by-step explanation:
−3x>24
Multiply both sides by (-1) (reverse the inequality)
(-3x)(-1)<24(-1)
Simplify;
3x<-24
Divide both sides by 3
3x/3<-24/3
Simplify
3x/3<-24/3
Simplify; 3x/3
=x
Simplify; -24/3
Divide the numbers;24/3=8
=-8
x<-8

Answer:
31.50
Step-by-step explanation:
One hundred volunteers who have agoraphobia (fear of open and crowded space) are available for a study. Fifty are selected at random and are given the drug imipramine, which is believed to be effective in treating agoraphobia. The other 50 are given a placebo. A psychiatrist evaluates the symptoms of all volunteers after two months to determine if there has been substantial improvement in the severity of their symptoms.
What type of study is this?
A. Matched pair design
B. Observational study
C. Completely randomized block design
D. Completely randomized design
Answer:
D. Completely randomized design
Step-by-step explanation:
Based on the description given about the experiment above and the manner in which the subjects were assigned to each of the treatment groups available, we can deduce that the study was conducted using a completely randomized design. The subjects weren't matched or blocked for any variable such as sex, height, age or any other variable. They were just evenly split randomly into the two available treatment levels ( those who receive the treatment and the placebo) group. With this design, all subjects have an equal chance of being in any of the two groups and the selection bias is almost totally eliminated using this sort of design as errors are being considered as arising from experimental faults.

Answer:
c
Step-by-step explanation:
first, find the area of the rectangle thing,
A = lw
14 x 8
112
but, there is a semicircle in it so you need to subtract that from it:
A = πr^2/2
A = π(4)^2/2
A = π16/2
A = 8π
A ≈ 25.132741228718346
then subtract that area from the area of the rectangle:
112 - 25.132741228718346
86.867258771281654
or about 89.9

Calculate for y given that mean of 20,2y,25,y,30 is 27
Answer:
y = 218
Step-by-step explanation:
Mean = (Sum of all numbers)/(How many numbers present)
27 = (20 + 2y + 25 + y + 30)/27
27 = (3y + 75)/27
3y + 75 = 729
3y = 729 - 75
3y = 654
y = 218
Below, the two-way table is given for a class of students. Freshmon Sophomora fontores Seniors Male 4 6 2 2 Female 3 4 6 б 3 Total If a student is selected at random, find the probability the student is a junior. Round to the nearest whole percent.
Answer:
22% probability the student is a junior.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes:
The table says that:
There are 4 + 6 + 2 + 2 + 3 + 4 + 6 + 6 + 3 = 36 total students.
2 + 6 = 8 are juniors.
If a student is selected at random, find the probability the student is a junior.
8/36 = 0.2222 = 22.22%
Rounding to the nearest whole percent, 22% probability the student is a junior.

Find the slope of the line passing through the points (-4,-5) and (3,-5).
Answer:
The slope of the line is 0, that is, it is a horizontal line.
Step-by-step explanation:
Slope of a line:
The slope of a line having two points in the format (x,y) is given by the change in y divided by the change in x.
(-4,-5) and (3,-5).
Change in y: - 5 - (-5) = -5 + 5 = 0
Change in x: 3 - (-4) = 3 + 4 = 7
0/7 = 0
The slope of the line is 0, that is, it is a horizontal line.

Answer:
[tex] \boxed{ m \overset{\huge\frown}{EFC} \: = \: 237°} [/tex]
Explanation:
Assuming that [tex] \overline{CF} [/tex] is a diameter, and that the angle of an arc subtending the central angle is congruent, [tex] m \overset{\Large\frown}{CGF} \: = \: 180° [/tex].
And according to the arc addition postulate, [tex] \overset{\Large\frown}{CG} + \overset{\Large\frown}{GF} \: = \: \overset{\huge\frown}{CGF} [/tex].
Using the substitution property:
[tex] \overset{\Large\frown}{CG} + \overset{\Large\frown}{GF} \: = \: 180° [/tex].
Given that [tex] m\overset{\Large\frown}{CG} \: = \: 140° [/tex].
Using the substitution property and that the measures apply to the arc addition postulate, [tex] 140° + m\overset{\Large\frown}{GF} \: = \: 180° [/tex].
[tex] 140° – \: 140° + m\overset{\Large\frown}{GF} \: = \: 180° – \: 140° [/tex].
[tex] m\overset{\Large\frown}{GF} \: = \: 40° [/tex].
Since [tex] \overset{\Large\frown}{GF} [/tex] and [tex] \overset{\Large\frown}{CD} [/tex] are subtending the center of the circle, they form vertical angles and are therefore congruent.
[tex] \overset{\Large\frown}{GF} \: \cong \: \overset{\Large\frown}{CD} [/tex]
According to the definition of a vertical angle, [tex] m \overset{\Large\frown}{CD} \: = \: 40° [/tex].
Using the arc addition postulate again,
[tex] \overset{\Large\frown}{CD} + \overset{\Large\frown}{DE} + \overset{\Large\frown}{EF} \: = \:\overset{\huge\frown}{CDF}/\overset{\huge\frown}{CEF} [/tex]
Using substitution, as well as how we are given that the central angle subtended by [tex] \overset{\Large\frown}{DE}[/tex] = 83°, we can find that:
[tex] 40° + 83° + \overset{\Large\frown}{EF} \: = \:\overset{\huge\frown}{CDF}/\overset{\huge\frown}{CEF} [/tex]
What is the z* critical value for constructing a 99% confidence interval for a proportion?
Find the z-table here.
1.65
1.96
2.33
2.58
Answer:
2.576
Step-by-step explanation:
The Z critical value for constructing a 99% confidence interval for a proportion is 2.58.
What is a z-score?A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.
For the given situation,
The confidence interval for a proportion = 99% = 0.99
Area to the left of a positive Z score in this standard normal distribution table is
⇒ [tex]\frac{1+confidence level}{2}[/tex]
⇒ [tex]\frac{1+0.99}{2}[/tex]
⇒ [tex]\frac{1.99}{2}[/tex]
⇒ [tex]0.995[/tex]
The corresponding Z score in the table for 0.995 is
⇒ [tex]2.5+0.08[/tex]
⇒ [tex]2.58[/tex]
Hence we can conclude that the Z critical value for constructing a 99% confidence interval for a proportion is 2.58.

The table below gives the number of men and women who work on the
three shifts at Factory X. Each worker at the factory works on exactly one
of the shifts. A worker is to be chosen at random from the factory. If the
worker chosen is a woman, what is the probability that she works on Shift
2?
O 3/16
O 3/10
O 3/8
O 7/13
The required probability that she works on Shift 2 is 3/8. Option C is correct.
The table below gives the number of men and women who work on the three shifts at Factory X. Each worker at the factory work on exactly one of the shifts. A worker is to be chosen at random from the factory. If the worker chosen is a woman, what is the probability that she works on Shift2 is to be determined.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
The total number of women working in all the 3 shifts = 560
number of women working in shift 2 = 210
probability of women chosen to work in shift 2 = 210/560
= 3/8
Thus, the required probability that she works on Shift 2 is 3/8. Option C is correct.
