Answer:
There will be approx 283908 hits.
Step-by-step explanation:
A website had 342,000 hits in 2011.
This is a decline of 2.3% from the previous year.
Decline rate = 2.3% or 0.023
So, increase rate will be [tex]1-.023=0.977[/tex]
Time = [tex]2019-2011=8[/tex]
We can calculate the answer as:
[tex]342000\times(0.977)^{8}[/tex]
= [tex]342000\times0.83014[/tex]
= 283907.88 rounding to 283908.
Therefore, there will be approx 283908 hits.

Eder needs 6 cookies and 2 brownies for every 4 plates he makes for a bake sale. How many cookies and brownies does
Eder need to make 10 plates?
Answer:
12 cookies and 10 brownies
Step-by-step explanation:
Eder needs 15 cookies and 5 brownies.
Given in the question is Eder needs 6 cookies and 2 brownies for 4 plates.
We have to calculate the cookies and brownies required for 10 plates.
Let's first calculate the cookies by unitary method.
∵ 4 plates required cookies = 6 cookies
∴ 1 plate will require cookies = 6/4
∴ 10 plates will require cookies = 6×10/4 = 15
Similarly we will calculate the brownies.
∵ 4 plates required number of brownies = 2
∴ 1 plate will require = 2/4 brownies
∴ 10 plates will require = 2×10/4 = 5 brownies
Therefore 15 cookies and 5 brownies will be required for 10 plates.

The following graph shows the number of customers who purchased something from a store in September and October. What is misleading about the graph?
A. The bars do not touch.
B. The intervals on the vertical axis between 200 and 207 are not even.
C. The graph exaggerated the difference in the number of customers between September and October.
D. The graph is not misleading
Answer:
C
Step-by-step explanation:
The graph is misleading because it exaggerates the difference. September had 202 customers and October had 206. That's a difference of 4 customers, which out of 202 isn't very much. The graph doesn't start at 0, and that's why it looks exaggerated.
The misleading about the graph
The graph exaggerated the difference in the number of customers between September and October.
Here the given graph is misleading because it exaggeration the difference,
As, September has 202 customer while October has 206 customers.
and, the difference in the customer is 4.
The difference is very minimum if remove from 202.
Also, the graph have a kink which shows the graph does not start from 0 and this is why the exaggeration is pronounced.

A company claims its washing machine produces 4000 joules of work output for every 3000 joules of work input. What would make you skeptical about this claim?
Things that make me skeptical: No evidence is provided, the company also claims that its washing machine produces 4000 joules of output for ever 3000 joules of input, and there is no possible way of creating a joule output larger than the input, unless your using coils to increase electricity, but that's not what washing machines have inside of their machinery.

Write the equation of G(x)
Answer:
[tex]G(x)=\frac{1}{2}(x-3)^3+2[/tex]
Step-by-step explanation:
The given function is
[tex]F(x)=x^{3}[/tex]
The transformations to this graph are in the form;
[tex]G(x)=a(x-b)^3+c[/tex]
where [tex]a=\frac{1}{2}[/tex] is the vertical compression by a factor of [tex]\frac{1}{2}[/tex]
b=3 is a shift to the right by 3 units.
c=2 is an upward shift by 2 units.
Therefore [tex]G(x)=\frac{1}{2}(x-3)^3+2[/tex]
Answer:
The equation is
[tex]G(x)=-\frac{1}{2}(x-3)^3 +2[/tex]
Step-by-step explanation:
If the graph of the function [tex]G(x)=cf(x+h) +b[/tex] represents the transformations made to the graph of [tex]y= f(x)[/tex] then, by definition:
If [tex]0 <|c| <1[/tex] then the graph is compressed vertically by a factor c.
If [tex]|c| > 1[/tex] then the graph is stretched vertically by a factor c
If [tex]c <0[/tex] then the graph is reflected on the x axis.
If [tex]b> 0[/tex] the graph moves vertically upwards.
If [tex]b <0[/tex] the graph moves vertically down
If [tex]h <0[/tex] the graph moves horizontally h units to the right
If [tex]h >0[/tex] the graph moves horizontally h units to the left
In this problem we have the function [tex]G(x)[/tex] and our parent function is [tex]f(x) = x^3[/tex]
We know that G(x) is equal to f(x) but reflected on the x-axis ([tex]c <0[/tex]), compressed vertically by a multiple of 1/2 ([tex]0 <|c| <1[/tex] and [tex]c = -\frac{1}{2}[/tex]), displaced 2 units upwards ([tex]b = 2>0[/tex]) and moved to the right 3 units ([tex]h = -3<0[/tex])
Then:
[tex]G(x)=-\frac{1}{2}f(x-3) +2[/tex]
[tex]G(x)=-\frac{1}{2}(x-3)^3 +2[/tex]

Rewrite 4n^2+2n as a factorial.
Answer:
4n²+2n as a factorial is given as:
[tex]= (2n+1)!/(2n-1)![/tex]
Step-by-step explanation:
We are given an expression which has to be converted into factorial form.
The expression is as follows:
[tex]4n^{2} + 2n\\ = 2n(2n+1)\\ = (2n+1)2n\\[/tex]
Now we know that 2n+1 and 2n differs by '1' and the next smaller term is '2n-1'.
Hence, multiplying and dividing by '(2n-1)!'; we get:
[tex]= ((2n+1)(2n)(2n-1)!)/(2n-1)![/tex]
we know that x(x-1)(x-2)! = x!, so:
[tex]= (2n+1)!/(2n-1)![/tex]
P(x|y)
What is this formula?
Answer:
If x and y are independent events;
[tex]P(x/y)=\frac{P(xny)}{P(y)}=\frac{P(x)*P(y)}{P(y)}=P(x)[/tex]
If x and y are dependent events then;
[tex]P(x/y)=\frac{P(xny)}{P(y)}[/tex]
Step-by-step explanation:
The expression;
P(x|y) in probability represents the conditional probability of an event x occurring given that an event y has already occurred. An example of such would be; the probability that a student passes the examination given that he attempted all the assignments.
If x and y are independent events, that is the occurrence of y does not in any way influence the occurrence of x, then;
[tex]P(x/y)=\frac{P(xny)}{P(y)}=\frac{P(x)*P(y)}{P(y)}=P(x)[/tex]
If x and y are dependent events then;
[tex]P(x/y)=\frac{P(xny)}{P(y)}[/tex]
[tex]P(xny)[/tex] represents the probability of both x and y occurring together;

Answer:
The correct option is C) 27
Step-by-step explanation:
Consider the provided figure.
Volume of a cone is: [tex]V=\frac{1}{3}\pi r^2h[/tex]
The area of base of the cone is = area of circle = [tex]\pi r^2[/tex]
Volume of the cone is 45 in³ and the area of base is given as 5 in²
Therefore, [tex]45=\frac{1}{3}\pi r^2h[/tex]
and [tex]5=\pi r^2[/tex]
Substitute the value of [tex]\pi r^2=5[/tex] in [tex]45=\frac{1}{3}\pi r^2h[/tex]
[tex]45=\frac{1}{3}\times 5\times h[/tex]
[tex]45\times \frac{3}{5}=h[/tex]
[tex]h=27[/tex]
Hence, the height of the cone is 27 in.
Therefore, the correct option is C) 27

z=y-4 -----> equation C
substitute equation B and equation C in equation A and solve for y
0.10(y+3)+0.05y+0.25(y-4)=2.10
0.10y+0.30+0.05y+0.25y-1=2.10
0.40y=2.10-0.30+1
0.40y=2.80
y=7 nickels
Find the value of x
x=y+3 -----> x=7+3=10 dimes

Which outcomes are in a or b is answer B
What is the value for x?
Answer:
x = 12
Step-by-step explanation:
Since all 3 angles are congruent then the triangle is equilateral, thus all 3 sides are also congruent.
Equate any 2 of the sides and solve for x
5x - 22 = 3x + 2 ( subtract 3x from both sides )
2x - 22 = 2 ( add 22 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Answer:
The value of x is 12
Step-by-step explanation:
* Lets talk about the equilateral triangle
- The three sides of the triangle are equal in length
- The three angles of the triangle are equal in measure
- To find the measure of each one divide the sum of the measures
of the angles of the triangle by 3
∵ The sum of the measure of the angles in any triangle = 180°
∴ The measure of each angle in the equilateral Δ = 180° ÷ 3 = 60°
* Now lets solve the problem
- From the figure the three angles have the same mark, that means
the three angles are equal in measure
∵ m∠A = m∠B = m∠C
∴ Δ ABC is equilateral triangle
∴ AB = BC = AC
- WE can use any two sides of them to find the value of x
∵ AB = 4x - 10
∵ BC = 3x + 2
∵ AB = BC
∴ 4x - 10 = 3x + 2 ⇒ add 10 and subtract 3x from both sides
∴ 4x - 3x = 2 + 10 ⇒ add the like terms
∴ x = 12
- To check the answer substitute the value of x in the 3 sides to
find the length of each side (they must have the same length)
∵ AB = 4x - 10
∴ AB = 4(12) - 10 = 48 - 10 = 38 units
∵ BC = 3x + 2
∴ AB = 3(12) + 2 = 36 + 2 = 38 units
∵ AC = 5x - 22
∴ AB = 5(12) - 22 = 60 - 22 = 38 units
- All the sides are equal, then the value of x is right
* The value of x is 12
