Find the inverse function for
Answer:
a. ∛(x+4)/3
Step-by-step explanation:
y = 3x³ -4
step 1: x = 3y³ - 4 (swap x and y)
step 2: 3y³ = x + 4
y³ = (x + 4) / 3
y = ∛(x+4)/3 (solve y)
f⁻¹(x) = ∛(x+4)/3 (inverse notation)

Jeff divided his 1,200 stamps equally among 7 stamp albums. Were there any stamps left over?
If so, how many?
Yes; there was 1 stamp left over.
Yes; there were 3 stamps left over.
Yes; there were 10 stamps left over.
No; there were no stamps left over.
Answer:
3 stamps were left over
Step-by-step explanation:
Division
When a number m divides evenly by n the remainder is 0. For example, 120 divides exactly by 30 because 120/30=4 and the remainder is 0.
But 120 does not divide exactly by 50 because 120/50 = 2 and leaves a remainder of 20.
Jeff divided his 1,200 stamps equally among 7 stamp albums. If the division of 1,200 by 7 was exact, there won't be any stamp left over. Let's test it.
1,200/7 is 171.4, obviously is not exact, thus There were stamps left over.
How many?
Multiply the lower integer of division 171 by 7 to get: 171*7 =1,197. This means that 1,200-1,197= 3 stamps were left over

A rectangle has a length of x +5 and a width of
X-7. Write an equation that describes the area, A,
of the rectangle in terms of x.
A = 2x + 12
b. A= 2x - 2
A=x2 + 12x - 35
d. A=x? - 2x - 35
Answer:
A=x2 - 2x -35
Step-by-step explanation:
x+5 x-7
The solution is Option D.
The area of the rectangle is A = x² - 2x - 35
What is the Area of a Rectangle?
The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the area of the rectangle be represented as A
Now , the value of A is
The length of the rectangle L = x + 5
The width of the rectangle is W = x - 7
And ,
The area of rectangle = L x W
Substituting the values in the equation , we get
The area of rectangle = Length of rectangle x Width of rectangle
The area of rectangle = ( x + 5 ) ( x - 7 )
On simplifying the equation , we get
The area of rectangle A = x ( x - 7 ) + 5 ( x - 7 )
The area of rectangle A = x² - 7x + 5x - 35
The area of rectangle A = x² - 2x - 35
Therefore , the value of A is x² - 2x - 35
Hence , the area of rectangle is x² - 2x - 35

One-hour carbon monoxide concentrations in air samples from a large city average 12 ppm (parts per million) with standard deviation 9 ppm.
Required:
a. Do you think that carbon monoxide concentrations in air samples from this city are normally distributed.
b. Find the probability that the average concentration in 100 randomly selected samples will exceed 14 ppm.
Answer:
0.0132
Step-by-step explanation:
No
Carbon monoxide concentrations sample in air from a large city are not normally distributed. This is often so because of the time of the day and that of the night. There exists different concentrations during the day, with respect to during the night. The companies and factories work during the day, so does most vehicles. This means that there tend to be a higher concentration during the day, than there will be during the night.
b)
Assuming that Y' is approximately normal, we can say that
P(Y' > 14) = P(Z > [√100(14 - 12)/9]) and this is equal to
P(Z > 2.22) = 0.013

2(2x+4)-3x=12
Answers
x=4
x=8
4
12
Answer: 4
Step-by-step explanation:
first you remove the parentheses it should look like this (4x+8-3x=12) then you collect the like terms (like terms have the same variable to the same power) it should look like this(x+8=12). then you move the constant to the right then last you calculate it should look like this x=12-8). then you subtract 12 by 8 and 4 is what you get.

Hey could anyone help me with this question :)
Answer:
cuz i am batman hhhhhhhhhhhh
Plzzz help mr plzzz mathhh
Answer:
x = 20
Step-by-step explanation:
First, we need to combine both equations as we know they are create a "straight angle", which is 180 degrees:
2x + 8 + 6x + 12 = 180
Next, we can combine like terms to simplify the equation:
8x + 20 = 180
Now, we can subtract 20 from each side:
8x = 160
Finally, we divide both sides by 8 to find the value of "x":
x = 20

From a population of 500 elements, a sample of 225 elements is selected. It is known that the variance of the population is 900. The standard error of the mean is approximately
Answer:
standard error of the mean (S.E) = 0.06
Step-by-step explanation:
Explanation:-
Given sample size 'n' = 500
Given variance of the Population = 900
The standard deviation of the Population = √900 = 30
The standard error of the mean is determined by
[tex]S.E = \frac{S.D}{\sqrt{n} } = \frac{30}{500} = 0.06[/tex]

Prove each of the following statements about integers by proving thecontrapositive of the statement.A. If 3nis even, thennis even.B. Ifx y zis odd, then at least one ofx; yandzis odd.
Answer and Step-by-step explanation:
(A) Suppose 3n is even, this implies that the product of 3n is a multiple of two, let's say 2(3k) where k is a real number. Rearranging that, we have 3(2k), let 2k = n. Therefore, n is even.
(B) Suppose xyz is odd, then let x = 2k, y = 2p + 1 and z = 2q + 1. xyz = 2k(2p + 1)(2q + 1) and this is obviously even since it is a multiple of 2.

Answer:
x= 5; Segment QR is the mid segment and YW is the base of the triangle. Mid segments are half the length of the base.
Step-by-step explanation:
2x - 3 = (x + 9) ÷ 2 Multiply both sides by 2
(2x - 3) • 2 = x + 9
4x - 6 = x + 9 Add 6 to both sides
4x = x + 9 + 6
4x = x + 15 Subtract x from both sides
4x - x = 15
3x = 15 Divide 3 on both sides
x = 15/3
x = 5
