Kasey asked 6 of her friends how many episodes of their favorite show they
watched during the quarantine. Kasey determined the following measures about
the number of episodes watched by the 6 friends. Mean: 10, Median: 9.5, and
Range: 14. The three friends who watched the most episodes over the quarantine
watched 18, 13, and 12. How many episodes did the other 3 friends watch?*
O A. 4,6,7
B. 4, 4,7
C. 5, 8, 9
O D. 2,3,5
Answer:
A
Step-by-step explanation:
6 friends
Mean - 10
Median - 9.5
Range - 14
3 friends watched 12, 13, and 18 movies.
Let's find the sum, this will help us find the total number of movies the other 3 friends watched.
12 + 13 + 18 = 43
The mean is all their movies added toether, divided by the number of friends.
m = number of movies the other friends watched.
(43 + m) / 6 = 10 Multiply each side by 6
43 + m = 10 * 6
43 + m = 60 Subtract 43 from each side
m = 60 - 43
m = 17
So we know the total movies the other friends watched is 3.
A. 4+6+7 = 17
B. 4+4+7 = 15
C. 5+8+9 = 22
D. 2+3+5 = 10
We know the answer is A.
We can check it by looking at the Median, the median is the middle number, if there are an even number of samples, you add the 2 middle numbers together and divide by 2.
4, 6, 7, 12, 13, 18
So 7+12 = 19
19/2 = 9.5
So we know for sure A is correct!
A cell phone company charges $4 per GB beyond 20GB in a month. The monthly plan is $59.99, and the bill for January is $75.99. How many GB were used in that month?
Answer:
24GB
Step-by-step explanation:
75.99-59.99=16 This is how much extra money was paid.
16/4=4 Divide this by the cost per GB.
20+4=24GB Add the 20GB included in the plan.
Answer:
Step-by-step explanation:
75.99-59.99=16
$16 worth of GB used for that month
which means 16/4=4 GB extra were used that month beyond the 20 GB
so total GB usage for that month is 24 GB
find three consecutive numbers such that three times the first number is equal to 9 more than the sum of the other two.
Answer:
12, 13, 14
Step-by-step explanation:
Three consecutive numbers means three numbers in a row, so if n is the first number, the second number is one more than n (which is n+1) and the third number is one more than that (which is n+2)
So three times (3 x) the first number (n) is equal to (=) nine more than (9 +) the sum of the other two ( (n+1) + (n+2) )
3 times n can be written as 3n
So 3n = 9 + (n+1) + (n+2)
3n = 9 + n + 1 + n + 2
3n = 9 + 1 + 2 + n + n
3n = 12 + 2n
Subtract 2n from each side
3n - 2n = 12 + 2n - 2n
1n = 12
n = 12
So the first number is 12, the second number is 12 + 1 (13) and the third number is 12 + 2 (14)
The numbers are 12, 13, 14
Hope this helps :)
Given x∥y and m∠2=23° .
What is m∠7?
Enter your answer in the box.
Answer:
angle2=23°
angle7=angle5
angle2=angle6
so,angle8=23°
total angle = 180°
angle7=180°-46°=134°÷2=67°
Using corresponding angles are equal property we found that m∠7 = 157°
What are corresponding angles?When two parallel lines are intersected by an transversal line then the pair of angles formed on one same side of transversal on both parallel lines are corresponding angles. As in the figure attached ∠ 1 and ∠5 are corresponding angles.∠4 and ∠8 are also corresponding angles.
Corresponding angles are always equal.
Given that x and y are parallel lines.
Then ∠2 and ∠6 are corresponding angles , therefore m ∠2 = m ∠6
Given that m∠2 = 23°
⇒ m∠6 = 23°
As ∠7 and ∠6 are on same line hence they are supplementary
m∠7 + m∠6 = 180°
⇒m∠7 + 23° =180°
⇒m∠7 =180°- 23° = 157°
Therefore, the measure of angle ∠7 is 157°

A salesman's salary is $9 per hour plus $250 in sales commission. His total weekly pay this week was $565. How many hours did the salesman work this week? Write an equation to model and solve the problem. Explain the answer in terms of the problem. Show all work.
muah
Answer:
565+9x=250.......
Step-by-step explanation:
um i think this might be it
Answer:
he worked 35 hours
equation: p= $9x + 250
p is pay
x is hours worked
Step-by-step explanation:
we know that the pay was 565 so plug that into p: 565= 9x + 250
subtract 250 from both side to isolate the variable: 315= 9x
divide both sides by 9: x= 35
solve 2r+3<7 and -r+9≤2
Answer:
r<2
r greater than or equal to 7
Step-by-step explanation:
The solution for r in the two of the given inequalities is r<2 and r ≥ 7, respectively.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The given inequalities can be solved as shown below.
1.)
2r + 3 < 7
Subtract 3 from both sides of the inequality,
2r + 3 - 3 < 7 - 3
2r < 4
Divide both the sides of the inequality by 2,
2r/2 < 4/2
r < 2
2.)
-r + 9 ≤ 2
Subtract 9 from both sides of the inequality,
-r + 9 - 9 ≤ 2 - 9
-r ≤ - 7
Multiply from both sides of the inequality by -1,
(-r × -1) ≤ (-7 × -1)
r ≥ 7
Hence, the solution for r in the two of the given inequalities is r<2 and r ≥ 7, respectively.

Bob has 10 apples after 4 hours he has 6 apples. Find the slope l the line that indicates the rate that bob eats apples at.
Answer:
y= -x + 10
Step-by-step explanation:
At 0 hours = Bob has 10 apples
At 4 hours = Bob has 6 apples
In 4 hours Bob has eaten 4 apples
Using linear graphs where y = the apples remaining and x = the hours passed
y = mx + c
We already know some coordinates:
(0,10) - 0 hours 10 apples remaining
(4,6) - 4 hours 6 apples remaining
c is the y intercept and m is the gradient
We already have the y intercept (where x = 0) which is (0,10)
So first part of our rule is done: y = mx + 10
The gradient is rise / run
Rise = -4 and Run = 4
-4/4 = -1
So the gradient is -1 and we add that to our rule
So final rule is y = -x + 10
