Using the following data, calculate the median.
22, 22, 18, 18
Answer:
20
Step-by-step explanation:
To find the median, first, arrange the numbers from smallest to greatest. We have 18, 18, 22, 22. Next, find the number in the center. In this case, there are two numbers in the middle and it doesn't easily fall under one number. In this case, find the average of the two numbers. We have (18+22)/2 = 20. Therefore, the median of 18, 18, 22, 22 is 20.

What is the slope of the line that passes through the points (−10,−8) and (−9,−8)? Write your answer in simplest form.
Answer:
slope=0
Step-by-step explanation:
The required slope of the line is zero which implies that the given line is parallel to the x-axis.
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
here,
The slope of the line that passes through the points (−10,−8) and (−9,−8) is given as,
m = (y₂ - y₁) / (x₂ - x₁)
Substitute values in the above equation,
m = -8 + 8 / -9 +10
m = 0
Thus, the required slope of the line is zero which implies that the given line is parallel to the x-axis.

The Sum of a number and two times a smaller number is 62. Three times the bigger number is C the smaller number by 116 the bigger number is? The smaller number is?
Answer:
x = 10
y = 42
Step-by-step explanation:
The sum of a number and two times a smaller number is 62
2x+y=62
so y=62−2x
Three times the bigger number exceeds the smaller number by 116
x+116=3y
substitute for y:
x+116=3(62−2x)
x+6x=186−116
7x=70
x=10
3y=10+116=126
#y = 126/3 = 42

When it is asking you to solve a system of equations, it means that it wants you to find the value of the variables, in this case, x and y.
3x + 2y = 1 -- equation 1
y = x - 12 -- equation 2
Put (equation 2)'s value of y into (equation 1)
3x + 2(x-12) = 1
3x + 2x - 24 = 1
5x - 24 = 1
5x = 25
x = 5 -- equation 3
Put (equation 3)'s values of x into (equation 2)
y = 5 - 12 = -7
Thus the solutions are x = 5 and y = -7 and we have solved the system of equations.

Ants have 6 legs. Katie and Lukas write equations showing the proportional relationship between the number of ants, a, and the number of ant legs, l.
Katie writes a = 6 • 1 and Lukas writes a = 1/6 • l.
Whose equation do you agree with?
A. Katie
B. Lukas
C. Both
D. Neither
Explain your reasoning.
Answer:
A
Step-by-step explanation:
I agree with Katie because number is legs is directly proportional to the number of ants.
1 ant has 6 legs.
So, 2 ants have 6 *2 = 12
3 ants have 6*3 = 18

three times y is less than or equal to half of x can be written
Answer:
3y ≤ 1/2x
Step-by-step explanation:
please give brainliest!!
3 times y is less than or equal to half of x can be written as 3y ≤ x/2 or x ≥ 6y.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given that,
three times y is less than or equal to half of x can be written.
Three times y means that 3 is multiplied to y.
Half of x means that x is multiplied to 1/2.
This is an inequality expression.
We can write it as,
3y less than or equal to x/2.
3y ≤ x/2
Multiplying both sides by 2,
6y ≤ x
or x ≥ 6y
Hence the inequality expression is x ≥ 6y.

f(n+1)=5f(n), where f(1)=3 and n>1
Answer:

Step-by-step explanation:
Let's assume the solution is of the form [tex]f(n) = \alpha k^n[/tex], where [tex]\alpha[/tex] is to be determined on the starting condition, and [tex]k \in \mathbb{R} \ne 0[/tex]
[tex]f(n+1) -5f(n) = 0\\\alpha k^{n+1} -5 \alpha k^n=0\\\alpha k^n (k-5) = 0 \rightarrow k= 5[/tex]
at this point we can use our starting condition to determine the value of [tex]\alpha[/tex]:

Leo practices piano for a
minimum of 90 minutes each
week. On Monday, he
practiced 10 minutes. For the
rest of the week, he practiced
in 20-minute sessions. How
many sessions would it take to
meet his goal?
Answer:
4 sessions.
Step-by-step explanation:
He starts with 10 minutes practiced and has to finish his quota in 20 minute sessions, so we can represent that with the equation 90=20x+10. Then solve for x.
90=20x+10
Subtract 10
80=20x
Divide by 20
x=4
It would take 4 sessions.
Answer:
1 10 min session + x 20 min sessions = 90 min
10+20x=90

Using the Intersecting Chords Theorem
For any two Intersecting Chords ---> UC*CW=TC*CV
By Substituting ---> 12(2x+5)=14(2x+2)
By Expanding ---> 24x+60=28x+28
Then --> 28x-24x=60-28
Then --> 4x=32
So x=32/4=8
Now to get UW,, UW=UC+CW=12+(2x+5)=2x+17
By Substituting by x=8
UW=2x+17=2*8+17=33

A circle with center O has a diameter of 26 cm. A chord, PQ, is 24 cm in length. How far is the chord from the center of the circle?
The chords from the center of the circle will be 5 cm. Apply pythogorous to find the distance of chords from the center of the circle.
What exactly is a circle?It is a point locus drawn equidistant from the center. The radius of the circle is the distance from the center to the circumference.
Given data;
Diameter,d=26 cm
Chord, PQ, = 24 cm
P is the chord from the center of the circle
All the given dimensions shown in the digrame are in the centimeter.
The chords from the center of the circle are found by the pythogorous theorem;
From Δ DCB
The value of the side p is;
h²=p²+b²
13²=p²+12²
169=p²+144
p=5 cm
Hence, the chords from the center of the circle will be 5 cm.

if 9 is added to a number x the result is greater than 17. Find the range of values of x
The solution of inequality shows that the range is x >8.
Domain and RangeThe domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined.
While the domain is related to the values of x, the range is related to the possible values of y that the function can have.
InequalitiesInequality is a mathematical expression that does not present equality between both sides. It is represented by symbols: <, ≤, > and ≥.
For solving this question, you should convert the text of the problem into an algebraic expression. Consequently, you will have:
x+9 > 17
x > 17-9
x > 8
Therefore, the range is x>8.
