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%.

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
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.

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.
Admission to the movies is $11. Mr. Cluff buys cotton candy for $6.50 each. He has $40 and MUST bring home change. Write the inequality.
Sean is running a 100 m dash. When the starter's pistol fires, he leaves the starting block and continues speeding up until 6 s into the race, when he reaches his top speed of 11 m/s. He holds this speed for 2 s; then his speed has slowed to 10 m/s by the time he crosses the finish line 11 s after he started the race. a. What was Sean's average acceleration during the first 6 s of the race? b. What was Sean's average acceleration from 6 to 8 s into the race? c. What was Sean's average velocity for the whole race? d. What was Sean's average acceleration from 8 to 11 s into the race?
Answer:
a. a = 1.83 m/s²
b. a = 0 m/s²
c. Average Velocity = 9.09 m/s
d. a = - 0.33 m/s²
Step-by-step explanation:
a.
We apply 1st equation of motion to the first 6 seconds of the motion:
Vf = Vi + at
a = (Vf - Vi)/t
where,
a = acceleration during first 6 seconds = ?
Vf = Final Speed = 11 m/s
Vi = Initial Speed = 0 m/s
t = time = 6 s
Therefore,
a = (11 m/s - 0 m/s)/6 s
a = 1.83 m/s²
b.
From 6 s to 8 s Sean held his speed constant at 11 m/s. Since, the speed was constant. Therefore, there is no acceleration during this time:
a = 0 m/s²
c.
Sean's average velocity can be found as follows:
Average Velocity = Total Distance Covered/Total Time
Average Velocity = 100 m/11 s
Average Velocity = 9.09 m/s
d.
Applying the 2st equation of motion for last 3 s from 8s to 11 s:
Vf = Vi + at
a = (Vf - Vi)/t
where,
Vf = 10 m/s
Vi = 11 m/s
t = 3 s
Therefore,
a = (10 m/s - 11 m/s)/3 s
a = - 0.33 m/s²

What is the equation of the line in slope-intercept form?
Answer:
y = 4/3x + 4
Step-by-step explanation:
y = mx + b is the formula for finding the slope intercept form equation
m = slope
b = y intercept
If you look at points (-3, 0) and (0, 4), you can calculate the slope
You have to go over, from point (-3, 0), 3 times, and up four to get to the point (0, 4)
Slope is change in y over change in x, so, if we look to see where the line crosses the y-axis, or vertical axis, we can see it reach the number four on the y-axis, b = 4
Now, lets create your equation...
y = 4/3x + 4

Answer:
c. <3 and <6: AE, alternate exterior
d. <9 and <14: CE, consecutive exterior
e. <4 and <7: CI, consecutive interior
f. <2 and <10: CA, corresponding angles
g. <8 and <14: CI, consecutive interior
h. <6 and <11: None
i. <4 and <13: None
j. <4 and <9: AI, alternate interior
Step-by-step explanation:
c. <3 and <6 are alternate angles located outside the parallel lines that are cut across by transversal c. Therefore they are alternate exterior angles.
d. <9 and <14 lie outside the parallel lines that are cut across by transversal d, and they are on the same side of the transversal. Therefore, they are consecutive exterior angles.
e. <4 and <7 lie within the parallel lines that are cut across by transversal c, and they are on the same side of the transversal. Therefore, they are consecutive interior angles.
f. <2 and <10 lie on the same position on each line cut across by the transversal line. Therefore they are corresponding angles
g. <8 and <14 lie on the same side of the transversal and are within the two lines cut across by a transversal. Therefore, they are consecutive interior angles.
h. <6 and <11 has no relationship. The answer is none.
i. <4 and <13 has no relationship. None is the answer.
j. <4 and <9 lie on alternate side of the transversal line and are within the two lines cut across by the transversal line. Therefore, they are alternate interior angles.
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]

What expression with an exponent shows the total number of pages in all of the newspapers? Explain how you found the answer. Use words, numbers, and/or pictures to show your work. Write your answers on the paper provided. I will give brainiest to best answer.plz help
Answer:
The total number of pages in all the newspaper is 390,625 pages
Step-by-step explanation:
The number of pages in the newspaper = 25 pages
The number of schools ordering the newspaper = 25 schools
The number of class rooms in each school = 25 classrooms
The number of students in each classroom = 25 students
Therefore;
The total number of pages in all the newspaper = 25 pages per paper × 25 schools × 25 classroom per school × 25 students per classroom
The total number of pages in all the newspaper = 25 × 25 × 25 × 25 = 25⁴
The total number of pages in all the newspaper = 25⁴ = 390,625 pages
