Complete question :
A video game developer wants to know how long it takes people to finish playing their new game. They surveyed a random sample of 13 players and asked how long it took them (in minutes).
1235
952
457
1486
1759
1148
548
1037
1864
1245
976
866
1431
Estimate the median time it will take all players to finish this game.
Find the interquartile range for this sample.
Answer:
1148 ; 549.5
Step-by-step explanation:
The ordered data:
457, 548, 866, 952, 976, 1037, 1148, 1235, 1245, 1431, 1486, 1759, 1864
The median value :
1/2 * (n +1)th term
n = 13
1/2 * 14 = 7th term
Median = 1148
The interquartile range :
Q3 - Q1
Q3 = 3/4(n+1)th term
Q3 = 3/4 * 14th term
Q3 = 10.5 th term
Q3 = (10 + 11)th term
Q3 = (1431 +1486) / 2= 1458.5
Q1 = 1/4(n+1)th term
Q1 = 1/4 * 14th term
Q1 = 3.5 th term
Q1 = (3 + 4)th term
Q1 = (866+ 952) / 2= 909
IQR = 1458.5 - 909 = 549.5
Answer:
Median:1054 mins
IQR:751.5

Nancy watches her dad fix a broken chair with a nail and a hammer, but she finds the hammering sound too loud. So, she decides to go back to her room, which is next door. On entering her room, she finds the hammering does not sound as loud. Why does the sound become faint?
Answer:
The sound of hammering becomes fainter as Nancy goes into her room because some of the sound waves are absorbed by the walls. Only part of the sound waves coming from the other room comes into her room, so the hammering sounds quieter.
I hope this helps. Good luck ^^

Find the midpoint of the segment with the following endpoints.
(-9,-8) and (-1,2)
Answer:
The midpoint is (-5, -3).
Step-by-step explanation:
Finding the coordinates of the midpoint consists of averaging the x-coordinates of the given points and then doing the same for the y-coordinates.
x coordinate of midpoint = (-9 - 1)/2 = -5
y coordinate = -6/2 = - 3
The midpoint is (-5, -3).

There are 10 girls and 5 boys in Ms. Sander's class. Each day, she randomly asks one student to take attendance. In 180 school days, which is the best prediction for the number of times that the student will be a girl?
Answer:
120
Step-by-step explanation:
The probability of a girl being picked one day = 10/15 = 2/3
Total number of days = 180
Therefore, the nunber of times it will be a girl = 2/3 x 180 = 2 x 60 = 120

Answer:
6.40312424
Step-by-step explanation:
5^2 + 4^2 = c^2
25 + 16 = c^2
41 = c^2
sqrt41 = c
c is equal to about 6.40312424 (round it if you need to)
Answer:
a^2+b^2=c^2
Step-by-step explanation:
5^2+4^2=6.403^2
c= 6.4
An amusement park charges an entrance fee of $20 and the rides cost $4 each. Suppose you write a function for the total cost for entering the park and riding a. Number of the rides. What is the domain of the function based on the given context?
Answer:
With the information provided, you can say that the total cost is equal to the entrance fee plus the price per ride for the number of rides, which would be:
C(x)=20+4x,where:
x is the number of rides
The domain of the function refers to all the inputs that the function can have and in this case, the domain consists of all real numbers greater than or equal to zero since x refers to the number of rides and it can't have a negative number.
3x+3 solve for x PLLSSSS HELP giving brainliest

Actually Welcome to the concept of Angles.
Here, total angle is 90°.
hence, 90° = x + 57°
so, ==> x = 90° - 57°
x = 33°
hence, x = 33°
Answer:
x=33°
Step-by-step explanation:
90-57=33. Basically, Q is 90°
help please!!!!!!!!!!!!!!
Answer:
x = 42,33°
Step-by-step explanation:
3x + 1° + 52° = 180° [angles on a straight line]
3x + 53° = 180°
3x = 180° - 53°
3x = 127°
divide both sides by 3
x = 42,33°

A farmer has 165 feet of fencing material in which to enclose a rectangular grazing area. He wants the
length x to be greater than 50 feet and the width y to be no more than 20 feet.
write a system of inequalities to represent this situation
Answer:
2*x + 2*y ≤ 165 ft
x > 50ft
0ft < y ≤ 20ft
Step-by-step explanation:
For a rectangle with length x and width y, the perimeter of the triangle is:
P = 2*x + 2*y
The perimeter needs to be equal or smaller than the length of fencing that the farmer has, then:
2*x + 2*y ≤ 165 ft
We also know that:
(x strictly larger than 50ft)
x > 50ft
(y can be, at most, 20 ft)
0ft < y ≤ 20ft
(where we added the restriction that y needs to be larger than zero, because we can not have a width equal or smaller than zero)
Then the system of inequalities that represent this situation is:
2*x + 2*y ≤ 165 ft
x > 50ft
0ft < y ≤ 20ft

Use a special right triangle to find the value of y. Write as a decimal rounded to the nearest 10th
Given:
The figure of a right angle triangle.
To find:
The value of y.
Solution:
in a right angle triangle,
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
In the given right triangle,
[tex]\sin 60^\circ=\dfrac{6}{y}[/tex]
[tex]\dfrac{\sqrt{3}}{2}=\dfrac{6}{y}[/tex]
On cross multiplication, we get
[tex]\sqrt{3}y=12[/tex]
[tex]y=\dfrac{12}{\sqrt{3}}[/tex]
[tex]y=\dfrac{12\sqrt{3}}{3}[/tex]
[tex]y=4\sqrt{3}[/tex]
Therefore, the value of y is [tex]4\sqrt{3}[/tex] units.

Find the perimeter of this shape please help I will award brainlisest
Answer:
22 cm
Step-by-step explanation:
Answer:
The shape is made up of a square and a rectangle.
So calculating the area of both the figures and then adding them would give us the required result.
Area of square = (a)² = (4)² = 16 sq unit.
Area of rectangle = l×b = 3×2 = 6 sq unit.
Now, the required area = 16 + 6 = 22 sq unit.

Grace, Maci, and Kendra all have a large collection of earrings.
The number of pairs of earrings in Grace’s collection is represented by x.
The number of pairs of earrings in Maci’s collection is three times the number of pairs in Grace’s collection.
Kendra has 4 earrings in her collection.
The total number of pairs of earrings in all three girls’ collections is 52.
How many pairs of earrings are in Maci’s collection?
Answer:
36
Step-by-step explanation:
Kendra has 4 so 52-4 (so it's out of the way) now you have 48
Divide 48 by 3 (leaves you 16). It can't be 16 because you have to add 16 and the sum of 16 x 3. So, go down a few numbers
12 + (12x3) = 48 plus Kendra's 4 is 52
A small theater had 6 rows of 23 chairs each. Workers just removed 9 of these chairs. How many chairs are left?
Answer:
129
Step-by-step explanation:
6 rows of chairs * 23 chairs in each row = 138 total chairs.
If 9 of these chairs were removed, that becomes 138 - 9 = 129.
There are 129 chairs left.

Charlotte needs 16 1/2 yards of fabric to make a quilt. She has one piece of fabric that is 3 1/2 yards and another piece of fabric that is 6 3/4 yards. How many more yards of fabric does Charlotte need to make the quilt?
YOUR ANSWER BETTER NOT HAVE A LINK OR YOU ARENT GETTING POINTS!
Answer:
6 1/4
Step-by-step explanation:
Add up the fabric that she has
3 1/2 + 6 3/4
Get a common denominator
3 2/4 + 6 3/4
9 5/4
9 4/4 + 1/4
10 1/4
Subtract this from the fabric that she needs
16 1/2 - 10 1/4
Get a common denominator
16 2/4 - 10 1/4
6 1/4

Can someone please help me to calculate this? I would really appreciate it. (-2)²(-3)³
Answer:
-108
Step-by-step explanation:
(-2)²(-3)³
When a number has an exponent, it means that the number is being multiplied to itself. For example, in (-2)², it means (-2) multiplied by itself twice since the exponent is 2. And for (-3)³, it means (-3) multiplied by itself 3 times since the exponent is 3.
= (-2)(-2)(-3)(-3)(-3)
Multiply. Remember that two negative numbers multiplied together make a positive number, and a positive and a negative number multiplied together make a negative.
= (4)(-3)(-3)(-3)
= (-12)(-3)(-3)
= (36)(-3)
= -108
Therefore, the answer is -108.
I hope this helps!
