Answer:
104
Step-by-step explanation:
In this set data set (82, 97, 98, 100, 102, 102, 106, 112) the median is 101
This means that the upper quartile is 104
To find the upper quartile, you take the numbers that come after the median, and find the median of that set. So when finding the upper quartile of this data set, you will only look at the numbers 102, 102, 106, 112, and the median of this is 104.
Answer:
104
Step-by-step explanation:
The upper quartile is the median of the upper half of the data set, and that is 104.

At Paul Bunyan’s tree farm they sell Fraser firs and blue spruce trees. They plant saplings of these two kinds of trees that are 8 inches in 5 inches tall, respectively. The Fraser firs grow at a constant rate of 12 inches per year, and a blue spruce trees grow at a constant rate of 14 inches per year. After how many years will these trees be at the same height? Express your answer as a common fraction.
Answer: 3/2
Step-by-step explanation:
Hi, to answer this question we have to write the next expressions::
Height 1= 8 +12 y
Height 2 =5 +14y
Where y = number of years
Since both heights must be the same
Height 1 = height 2
8+12y = 5+14y
solving for y:
8-5 =14y-12y
3 = 2y
3/2 =y
y = 3/2 years
Feel free to ask for more if needed or if you did not understand something.
8 + 12y = 5 + 14y
12y + 8 = 14y + 5
12y + 8 - 8 = 14y + 5 - 8
12y = 14y - 3
12y - 14y = 14y - 3 - 14y
-2y = -3
(-2y)/-2 = -3/-2
y = 3/2

1. f(x) = x² - 4 ; if x is even = 3x – 2; if x is odd solve for f(4) and f(5)
=======================================================
Explanation:
This is a piecewise function as it is composed of two pieces.
The equation for f(x) depends on what x is. Specifically whether it is even or odd.
If x is even, then f(x) = x^2-4. If x is odd, then f(x) = 3x-2
------------
f(4) means f(x) when x = 4. We have an even number input for x, so we'll go with f(x) = x^2-4
f(x) = x^2 - 4
f(4) = 4^2 - 4
f(4) = 16 - 4
f(4) = 12
------------
When x = 5, x is now odd, so use f(x) = 3x-2
f(x) = 3x-2
f(5) = 3(5) - 2
f(5) = 15 - 2
f(5) = 13
How to find constant M ? did I do anything wrong here ?
Answer:
M=-1, N=7
Step-by-step explanation:
Something went wrong on the 4th line.
From the third line, it should read
2x^2-x+6Mx-3M+4
=x(2x-1+6M) - 3M+4
Equating with the RHS,
2x-1+6M = 2x-7
6M = -7+1 = -6
M = -1
Therefore
N = -3M+4 = -3(-1)+4 = 7
or
M=-1, N=7
P(n) models the probability, when rolling a pair of dice, of obtaining two numbers whose sum is n 2 6 7 P(n) 1/36 5/36 6/36 when does the probability increase faster? a)Between a sum of 2 and a sum of 6 b) Between a sum of 6 and a sum of 7 c)the probability increases at the same rate over both intervals
Answer:
Option c.
Step-by-step explanation:
From the given table, it is clear that
[tex]P(2)=\dfrac{1}{36}[/tex]
[tex]P(6)=\dfrac{5}{36}[/tex]
[tex]P(7)=\dfrac{6}{36}[/tex]
The increasing rate of probability between a sum of 2 and a sum of 6 is
[tex]r_1=\dfrac{P(6)-P(2)}{6-2}[/tex]
[tex]r_1=\dfrac{\dfrac{5}{36}-\dfrac{1}{36}}{4}=\dfrac{1}{36}[/tex]
The increasing rate of probability between a sum of 6 and a sum of 7 is
[tex]r_2=\dfrac{P(7)-P(6)}{7-1}[/tex]
[tex]r_2=\dfrac{\dfrac{6}{36}-\dfrac{5}{36}}{1}=\dfrac{1}{36}[/tex]
Since [tex]r_1=r_2[/tex], therefore the probability increases at the same rate over both intervals.
Hence, the correct option is c.
Answer:
c)the probability increases at the same rate over both intervals

Answer:
4 cm (A)
Step-by-step explanation:
triangle BAC is just a larger version of triangle EAD. given that ED is 5cm, and BC is 10cm, triangle BAC must be twice the size of EAD. since the ratio of AD to ED is 4:5, and BC is twice the size, all we need to do is multiply both sides by 2 to find length AC. 4*2 = 8. now we can subtract length AD from AC to get CD. 8 - 4 = 4.

Find the value of x in the isosceles triangle shown below.
Answer:
x=10
Step-by-step explanation:
We can use the Pythagorean theorem to find x
The height meets the base at a right angle
The base is bisected ( cut in half) so the base is 6 the height is 8
a^2 + b^2 = c^2
6^2 + 8^2 = x^2
36+64 = x^2
100 = x^2
Taking the square root of each side
sqrt(100) = sqrt(x^2)
10 = x
Answer:
10
Step-by-step explanation:
This triangle is divided into 2 identical rigth triangles.
We will use the pythagorian theorem:
●8^2+ (12/2)^2 =x^2
● 64 + 36 = x^2
● x= 10
So x is 10

A person stands 12 meters east of an intersection and watches a car driving away from the intersection to the north at 4 meters per second. At a certain instant, the car is 9 meters from the intersection. What is the rate of change of the distance between the car and the person at that instant (in meters per second)?
Answer: the rate of change of the distance between the car and the person at that instant is 4 meters per second
Step-by-step explanation:
According to the Pythagorean theorem, we have:
d^2 = (12^2 + 9^2)
Differentiating both sides with respect to time:
2d * (dd/dt) = 0 + 2(9) * (9''), Simplifying the equation, we get:
2d * (dd/dt) = 2(9) * (9'')
Substituting the given values:
2d * (dd/dt) = 2(9) * (4) [the car is moving at a constant velocity of 4 m/s]
Simplifying further:
2d * (dd/dt) = 72
we divide both sides by 2d:
dd/dt = 72 / (2d)
substitute this value into the equation to find the rate of change of the distance:
dd/dt = 72 / (2 * 9) = 4 m/s
The rate of change of the distance between the car and the person at that instant is -12/5 meters per second.
Given information:
The person is standing 12 meters east of the intersection.
The car is driving away from the intersection to the north at a constant speed of 4 meters per second.
At a certain instant, the car is 9 meters from the intersection.
Using the Pythagorean theorem, determine D(t) in terms of the car's distance from the intersection, which we'll call x(t).
Since the person is 12 meters east of the intersection, the distance D(t) can be expressed as:
[tex]D(t) = \sqrt{(x(t)^2 + 12^2)[/tex]
Differentiating both sides of the equation with respect to time, we get:
[tex]dD/dt = (1/2) * (x(t)^2 + 12^2)^{(-1/2)} * 2x(t) * dx(t)/dt[/tex]
So, dx(t)/dt = -4
Substituting this value into the equation for dD/dt, we have:
[tex]dD/dt = (1/2) * (x(t)^2 + 12^2)^{(-1/2)} * 2x(t) * (-4)[/tex]
[tex]dD/dt = -4x(t) / \sqrt{(x(t)^2 + 144)[/tex]
At the instant when the car is 9 meters from the intersection, substitute x(t) = 9 into the equation:
[tex]dD/dt = -4(9) / \sqrt{(9^2 + 144)[/tex]
= -36 / √(81 + 144)
= -36 / √225
= -36 / 15
= -12/5
Therefore, the rate of change is -12/5 meters per second.

A particular movie theater charges $7.00 per adult and $4.50 per child. Suppose 450 people attended a movie and the total revenue from ticket sales was $2650. Write linear equations for the two constraints, where z represents the number of adults attending the
movie and y represents the number of children attending the movie. 1= ,2=?
Answer:
7z + 4.5y = 2650
z + y = 450
Step-by-step explanation:
The first equation represents the amount of money made from ticket sales for both adult and child tickets.
The second equation represents the amount of customers, both adult and child, that attended the theatre.
Using both equations you cans find the number of adults and children that attended the theatre.
Cheers.
-----------------------------------------------------
Edit: Solving for the variables
There are two easy ways to solve for these values. The first is using an augmented matrix and solving with that method.
7 4.5 | 2650
1 1 | 450
After are augmented matrix is set up, we simply use row operations on the matrix to solve for 1s on the diagonal.
The second method for solving is equation addition or variable substitution to solve for each variable.
7z + 4.5y = 2650
z + y = 450
7(450-y) + 4.5y = 2650
3150 - 7y + 4.5y = 2650
-2.5y = -500
y = 200
Plug back in y into one of the equations to solve for z.
z + 200 = 450
z = 250
So there were 250 adults and 200 children.
