The table shows the number of candid pictures of students for the yearbook for two consecutive years. Year Number of Photos 2015 236 2016 214 What was the percent of decrease in the number of candid student pictures from 2015 to 2016, rounded to the nearest tenth?
Answer:
The percentage decrease in the number candid student pictures for the yearbook from 2015 to 2016 is approximately 9.3 percent
Step-by-step explanation:
The given data can be presented as follows
Year [tex]{}[/tex] Number of Photos
2015 [tex]{}[/tex] 236
2016 [tex]{}[/tex] 214
The percentage decrease in the number of candid pictures is give by the following formula
[tex]Percentage \ Decrease = \dfrac{Original \ Value- New \ Value}{Original \ Value} \times 100[/tex]
Where;
Original value for the number of pictures = 236
New value for the number of pictures = 214
Substituting the values into the equation for the percentage decrease gives;
[tex]Percentage \ Decrease = \dfrac{236- 214}{236} \times 100 = \dfrac{550}{59} \ percent\approx 9.3 \%[/tex]
The percentage decrease is approximately 9.3 percent.
Answer:
The answer is 9.3%.

Decide wether or not if these are functions
Answer:
Relation 1: Not a Function
Relation 2: Not a Function
Relation 3: Function
Relation 4: Not a Function
Explanation:
There can only be one output (what you get out of it) for each input (what you put into the function) in a function.
Determine whether each function has a maximum or minimum value, and find that value. Then state the domain and range of the function.

During the life of a $2500 loan, the interest paid is $318.75. If the interest rate is 8.5%, how long was the loan?
Answer:
1.5 years
Step-by-step explanation:
Simple Interest I = PRT
Principal = 2500, Rate R= 8.5%, SI = 318.75, T = ?
Now, substituting the above value
318.75 = 2500*0.085 * T
T = 318.75 / 2500*0.085 years
T = 318.75 / 2500*0.085 years
T = 318.75 / 212.5 years
T = 1.5 years

Okay so my test said (using elimination (add or sub) find the solution to the following system of equations. 5x+3y=9 2x -3y=5) and I’m confused
Answer:
x = 2, y = -1/3
Step-by-step explanation:
I'm pretty sure the question is asking for the values of x and y. By finding these values you will need to use elimination.
Equations given:
5x + 3y = 9
2x - 3y = 5
To find x:
5x + 3y + 2x - 3y = 9 + 5 (add to eliminate y to solve for x)
7x = 14
x = 2
To find y:
5(2) + 3y = 9
10 + 3y = 9
3y = -1
y = -1/3
Therefore, x = 2 and y = -1/3

How many pushups someone can do can be correlated to the distance they run. The regression equation for this is pushups = 0.72 + 7.62 miles. When you used the equation to determine how many miles someone should be able to run if that person does 24 push-ups, was that an example of interpolation or extrapolation?
Answer:
Extrapolation
Step-by-step explanation:
Given the regression equation :
pushups = 0.72 + 7.62 miles
Determining the Number of miles a person who does 24 push-ups should be able to run is an example of extrapolation, this is because we are making a prediction into the the future or outside our data based on the available information. Regression equations are used for extrapolation (making future predictions). Interpolation on the other hand makes estimation within the limit of the data usually between two known values.

7. Find DE.

E
А
4x + 1
D
С
Answer:
DE = 37Step-by-step explanation:
AD = DC and BE=EC ⇒
DE = 1/2AB
4x + 1 = 1/2(11x - 25)2(4x + 1) = 11x - 258x + 2 = 11x - 2511x - 8x = 2 + 253x = 27x = 27/3x = 9DE = 4*9 + 1 = 36 + 1 = 37
AD = DC
BE = EC
It gives that 2(DE) = AB
To Find:The length of DE.
Explanation:According to the question,
2(DE) = AB
By putting the respected values, we get
2( 4x + 1 ) = 11x - 25
or, 8x + 2 = 11x - 25
or, 25 + 2 = 11x - 8x ( transposition method )
or, 27 = 3x
or, x = 27/3 = 9
The value of x is 9.
DE = 4(9) + 1 = 36 + 1 = 37
Answer:DE = 37
Determine f(4) for the function f(x)=2/5x+11
Answer:
63/5 in improper form and 12 and 3/5 in mixed form
Step-by-step explanation:
f(x) = 2/5x + 11
Substitute in value of x for the equation
f(4) = 2/5(4) + 11
f(4) = 8/5 + 11
f(4) = 8/5 + 55/5
f(4) = 63/5 or 12 and 3/5
So, the answer should be 63/5 in improper form and 12 and 3/5 in mixed form.
Answer:
Step-by-step explanation:
f(x) = [tex]\frac{2}{5}x + 11[/tex]
f(4) = [tex]\frac{2}{5}*4 +11\\[/tex]
[tex]=\frac{8}{5}+11\\\\=\frac{8}{5}+\frac{11*5}{1*5}\\\\=\frac{8}{5} + \frac{55}{5}\\\\=\frac{63}{5}\\\\=12\frac{3}{5}[/tex]
Select from the drop-down menus to correctly complete the statement. To find the product of 183.5 and 10², move the decimal point in 183.5 _____ places to the right because 10² has _____ zeros.
Given :
To find the product of 183.5 and 10², move the decimal point in 183.5 _____ places to the right because 10² has _____ zeros.
To Find :
We need to fill the spaces.
Solution :
We know, when number with positive power of 10 is multiplied with another number we need to shift the number to the right hand side by the number of zeroes.
So, To find the product of 183.5 and 10², move the decimal point in 183.5 to right places to the right because 10² has two zeros.
Hence, this is the required solution.
An isosceles triangle has a perimeter of 50 cm. The congruent sides
measure (2x + 3) cm. The length of the third side is 7x cm. What is the
value of x?
Answer:
4
Step-by-step explanation:
As, the measure of one congruent side is = 2x + 3
So, bc there are 2 congrent sides, =( 2x + 3) + (2x +3) = 4x + 6
Now perimeter= the length of the 2 sides + third side
Perimeter = (4x + 6) + (7x) = 50 cm
So, 11x + 6 = 50
So, 11x = 50 - 6 = 44
11x = 44
x = 44/11
x = 4cm.
What is the vertex of (x) = –16x² + 64x + 80.
Answer:
(2, 124)Step-by-step explanation:
f(x) = a(x - h)² + k - the vertex form of the equation of the parabola with vertex (h, k)
[tex]f(x) = -16x^2+ 64x + 80\\\\f(x) = -16(x^2- 4x) + 80\\\\f(x) = -16(\underline {x^2-2\cdot2x\cdot2+2^2}-2^2) + 80\\\\f(x) = -16\big[(x-2)^2-4\big] + 80\\\\f(x) = -16(x-2)^2+64 + 80\\\\\bold{f(x)=-16(x-2)^2+124\quad\implies\quad h=2\,,\quad k=124}[/tex]
The vertex is (2, 124)

Five people are at a party. Everyone shakes hands once with everyone else. How many handshakes are there? Show your
work.
HELP ASAP PLEASE!!!!!
Answer:
10
Step-by-step explanation:
1 2 3 4 5
1 shakes hands with 2,3,4,5
2 shakes hands with 3,4,5 but not with 1 because they already shook hands once
similarly, 3 only shakes hands with 4 and 5, same reason as abov
4 with 5 only, same reason
Answer:
10
Step-by-step explanation:
Let the people be represented by numbers (1,2,3,4,5)
-- now 1 shakes hands with the remaining 4, (i.e 2,3,4,5)
-- 2 shakes hands with the remaining 3 (i.e 3,4,5) as it has already shaken hands with 1
-- 3 shakes hands with the remaining two and so on
If you recognize the pattern there are 4+3+2+1 handshakes that have taken place, or 10 handshakes

Deeana say that the human beats an average of 80 beats per minute.she said that means that the human heart beats 4.8 times 10^3 beats per hour.Is she correct?Explain.
Answer:
Deana's claim is correct that the heart beats 4.8*10^3 times per hour.
Step-by-step explanation:
Given that human heart beats 80 time per minute.
In order to check Deana's claim we have to calculate number of beats in one hour.
As we know that
1 hour = 60 minutes
So the heartbeats in 60 minutes:
[tex]= beats\ per\ minute * 60\\=80*60\\=4800\ beats[/tex]
Converting the result into scientific notation gives us:
[tex]4800 = 4.8 * 1000 = 4.8*10^3\ beat[/tex]
Hence,
Deana's claim is correct that the heart beats 4.8*10^3 times per hour.
