Find the median of the data set.2, 33, 23, 37, 45, 5, 49, 27, 48
Answer:
MEDIAN: 33Step-by-step explanation:
The median is the middle number of the data set.
So first we have to arrange all of the numbers from least to greatest order.
2, 33, 23, 37, 45, 5, 49, 27, 48
arranged order:
2, 5, 23, 27, 33, 37, 45, 48, 49
all you need to do is to find the middle number of the data set
(note: the data set is the group of numbers listed altogether)
2, 5, 23, 27, 33, 37, 45, 48, 49
median: 33

If f(x)=|x−4|+5, find f(1).
Answer:
8
Step-by-step explanation:
To find f(1), substitute x = 1 into the given function f(x)
(output values from an absolute value become positive)
[tex]f(1) = |1-4|+5\\f(1)=|-3|+5\\f(1)=3+5\\f(1)=8[/tex]

- 6x < 24
solve for x and what’s the solution?
Answer:
x > -4
Step-by-step explanation:
In order to get x by itself, you divide -6 on both sides. So, -6x divided by -6 = x and 24 divided by -6 equals -4.
However, the answer is not x < -4 because a rule of inequalities states that any time you divide or multiply both sides of an inequality by a negative number, the inequality sign is flipped. So, the answer is x > -4
Answer:
x > -4
Step-by-step explanation:
- 6x < 24
Divide each side by -6, remembering to flip the inequality
-6x/-6 > 24/-6
x > -4
point to a parallel line (8,-8); 9x - 4y= 7
Answer:
y = 9/4x - 26
Step-by-step explanation:
9x - 4y= 7
-4y = -9x + 7
y = 9/4x - 7/3
y = 9/4x + b
-8 = 9/4(8) + b
-8 = 18 + b
-26 = b

The diameter of a circle is 2 centimeters. What is the area?
d=2 cm
Answer: 4π cm or 12.56 cm
Step-by-step explanation: To find the circumference of this circle, start with the formula for the circumference of a circle which is C = 2πr.
Since the radius is 2 centimeters, we can
plug in 2 centimeters for r in the formula.
So we have (2)(π)(2 cm) which is equal to 4π cm.
So the circumference of this circle is 4π cm.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.
So we have (4)(3.14) which is equal to 12.56.
So the circumference of the circle is
approximately equal to 12.56 cm.
Perform the operation. Enter your answer in scientific notation.

Answer:
Tn2= 6
Tn3=-12
Tn4= 24
Tn5= -48
Step-by-step explanation:
Tn= ar^n-1
Now
Tn1= -3×-2^1-1
=-3×-2^0
= -3×1= -3
Tn2= -3×-2^2-1
= -3×-2=6
Tn3= -3×-2^3-1
= -3×-2^2
=-3×4= -12
Tn4= -3×-2^4-1
= -3×-2^3
= -3×-8= 24
Tn5= -3×-2^5-1
= -3×-2^4
= -3×16= -48

5x+2+2x-10
Answer:
7x - 8
Step-by-step explanation:
5x + 2 + 2x - 10
Rearrange terms:
5x + 2x - 10 + 2
Combine like terms (add 2x and 5x):
= 7x - 10 + 2
Combine like terms (add -10 and 2):
= 7x - 8 (This is the simplified form).
