Answer:
The median for X is "33"
The median for F is "10.5"
Step-by-step explanation:
Answer:
33 and 10.5
Step-by-step explanation:
The median is the middle number in the data set arranged in ascending order.
If there is no exact middle value then it is the average of the 2 numbers either side of the middle.
X 20 25 29 33 38 42 43
↑ middle number
Thus the median = 33
Arrange set F in ascending order.
F 1 2 4 6 15 20 24 28
↑ middle between 6 and 15
Thus the median = [tex]\frac{6+15}{2}[/tex] = [tex]\frac{21}{2}[/tex] = 10.5
what is the inverse of y + 6 = 3x?
Greetings from Brasil...
To find the inverse of a function, just replace X for Y and vice versa
Y + 6 = 3X replacing X by Y
X + 6 = 3Y isolating y
(X + 6)/3 = Y⁻¹
Then the inverse of Y + 6 = 3X will be
Y⁻¹ = (X + 6)/3URGENT PLEASE HELP
x/240 = 82/100 what is X?
x/240 = 82/100
240 : 100 = 2.4
so 240 is divided with 2,4 giving 100, this will work with 82 too. So, 82 × 2.4 = 196,8
Answer : x = 196,8
prove :
196,8/240 = 82/100 = 41/50

The sum of three consecutive numbers is 45 what is the smallest of the three numbers
the smallest of the three numbers is 14
Step-by-step explanation:Hi there !
three consecutive numbers a ; b ; c
b = a + 1
c = a + 2
a + b + c = 45
replace b ; c
a + (a + 1) + (a + 2) = 45
3a = 45 - 3
3a = 42
a = 42 : 3
a = 14
Good luck !

Points A, P and B are collinear such that P sits on line segment AB and partitions the segment so that AP to PB is in the ratio 2:3. Point A is located at (3,-1) and B is located at (8,14). Find the coordinates of P, the partition point.
Answer:
P = (5, 5)
Step-by-step explanation:
For the given division, ...
P = (2B +3A)/5
P = (2(8, 14) +3(3, -1))/5 = (16+9, 28-3)/5 = (25, 25)/5
P = (5, 5)
_____
For some division ratio of AP : PB = p : q, we have ...
(P -A)/(B -P) = p/q
q(P -A) = p(B -P)
P(p+q) = pB +qA . . . . rearranging
P = (pB +qA)/(p+q) . . . . . the formula we used above

Step-by-step explanation:
if angle w and angle v are supplementary angles and angle v=49, find angle w
Answer: 131°
Step-by-step explanation:
Supplementary angles are the angles that when we add them together, their sum is equal to 180°.
From the question, we are informed that angle w and angle v are supplementary angles and angle v=49.
V + W = 180°
49° + W= 180°
W = 180° - 49°
W = 131°
Andre's coin jar contains 85 cents. There are no
quarters or pennies in the jar, so the jar has all
nickels, all dimes, or some of each.

1) Write an equation that relates the number of
nickels, n, the number of dimes, d, and the
amount of money, in cents, in the coin jar.
Can You please help me on this they don’t have what I’m looking for.
===========================================================
Explanation:
n = number of nickels
d = number of dimes
Since each nickel is 5 cents, and each dime is 10 cents, we can say
5n = value of all the nickels (ignore the dimes) in cents
10d = value of all the dimes (ignore the nickels) in cents
5n+10d = value of all the coins (nickels+dimes) in cents
5n+10d = 85 is the equation we're after
-----------------------
Extra Info:
We don't have enough info to be able to solve for n and d.
The list of all possible solutions are
n = 17, d = 0n = 15, d = 1n = 13, d = 2n = 11, d = 3n = 9, d = 4n = 7, d = 5n = 5, d = 6n = 3, d = 7n = 1, d = 8Note how each time n drops by 2, d goes up by 1.
This is because 2 nickels = 1 dime.
In other words, for every 2 nickels we take away, we add on 1 dime. This works in reverse as well (for every dime removed, add 2 nickels).
The equation to represent the given situation is 5n+10d = 85.
Given that, Andre's coin jar contains 85 cents.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, n = number of nickels and d = number of dimes.
Since each nickel is 5 cents, and each dime is 10 cents, we can say
5n = value of all the nickels (ignore the dimes) in cents
10d = value of all the dimes (ignore the nickels) in cents
So equation is 5n+10d = value of all the coins (nickels + dimes) in cents
That is, 5n+10d = 85
Therefore, the equation to represent the given situation is 5n+10d = 85.

angle, a and angle, b are complementary angles. angle a measures 22, degrees. What is the measure of angle b?
The measure of angle b would be 68 degrees.
What are complementary angles?
If two angles are given and the sum of the angles of two angles is 90 degrees then the angles are called as complementary angles.
Complementary angles are two angles whose sum is 90 degrees.
Given that angle a measures 22 degrees and it is complementary to angle b, we can use the following equation to find the measure of angle b:
a + b = 90
Substituting the given value of angle a, we get:
22 + b = 90
Subtracting 22 from both sides, we get:
b = 90 - 22
Therefore, the measure of angle b is:
b = 68 degrees.
Hence, the measure of angle b would be 68 degrees.
