what is the median !!! help!! alegbra 2. marking brainliest
Answer:
The answer is 8.5
Step-by-step explanation:
Just list all the numbers and cross them out one by one.
Add up all of the numbers and divide by the number of numbers in the data set. The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median.

Dustin has a spinner that is divided into 5 equal-size sections colored pink, blue, orange, white, and green. What is the probability that Dustin spins pink on the 1st spin and then spins a color other than pink on the 2nd spin?
Answer:
1/6
Step-by-step explanation:
1st spin:
1 out of the 5 sections are pink, so the probability of spinning a pink on the 1st spin is 1/5.
2nd spin:
5 out of the 6 sections are not pink, so the probability of spinning a pink on the 2nd is 5/6.
Multiply the probabilities of the two spins to get the answer.
[tex]\frac{1}{5} *\frac{5}{6} =\frac{5}{30} =\frac{1}{6}[/tex]
use the matrix tool to solve the system of equations enter the answer as an ordered pair. 8x+5y=9 -x+y=7
Answer:
x = -44/13
y = -65/13
Step-by-step explanation:
Using matrix form means using the crammers rule
The matrix form of the expression is written as;
[tex]\left[\begin{array}{ccc}8&5\\-1&1\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}9\\7\\\end{array}\right][/tex]
AX = B
taking the determinant of A;
|A| = 8(1) - 5(-1)
|A| = 8 + 5
|A| = 13
After replacing the first row with the column matrix;
[tex]A_x =\left[\begin{array}{ccc}9&5\\7&-1\\\end{array}\right][/tex]
|Ax| = 9(-1)-5(7)
||Ax| = -9 - 35
|Ax| = -44
x = |Ax|/|A|
x = -44/13
similarly for y
[tex]A_x =\left[\begin{array}{ccc}8&9\\-1&7\\\end{array}\right][/tex]
|Ay| = 8(7)+9
|Ay| = 56+9
|Ay| = 65
y = |Ay|/|A|
y = -65/13
how many lines of semmetry does a rectangle have
Answer:
A rectangle has 2 lines of symmetry
Give the domain.
y =2 / (5x - 4)(4x - 9)
Answer:
x ≠ 4/5, x ≠ 9/4
You can also write it as "all real numbers except 4/5 and 9/4."
Step-by-step explanation:
The denominator of a fraction cannot equal 0. We can write this relation to find what x does NOT equal:
(5x - 4)(4x - 9) ≠ 0
We can use the zero-product property to get two separate equations:
5x - 4 ≠ 0
5x ≠ 4
x ≠ 4/5
4x - 9 ≠ 0
4x ≠ 9
x ≠ 9/4
Slope of the line that passes through (8,-9) and (14,-9)
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, - 9) and (x₂, y₂ ) = (14, - 9)
m = [tex]\frac{-9+9}{14-8}[/tex] = [tex]\frac{0}{6}[/tex] = 0
Select the correct answer. What is the approximate distance between points D and E? Round your answer to the nearest hundredth. A.
Answer:
The approximate distance between points D and E is 8.25
Step-by-step explanation:
The figure is as follows :
To find - What is the approximate distance between points D and E ?
Solution -
By Pythagoras Theorem, we get
(DE)² = (FE)² + (DF)²
= (8)² + (2)²
= 64 + 4
= 68
⇒(DE)² = 68
⇒DE = √68
⇒DE = 8.246
∴ we get
The approximate distance between points D and E is 8.25

no lol
Step-by-step explanation:
Answer:
i will tell you what to do and then you do the work
Step-by-step explanation:
arrange the numbers from lowest to largest
count the amount of numbers to find how many students wrote each test
to find the mean add all of the numbers up then divide by the amount of numbers there are
to find the mode it that is the number that appears the most or the most common value
to find the median is the middle number, when you put it from lowest to largest, it will be the middle number

Use a calculator
find the area of the triangle
Please help
need the correct answer
Urgent
Please do not answer from links
will give the brainliest!
Answer:
[tex] \rm \displaystyle A_{ \text{triangle}} = \frac{147 \sqrt{7} }{2 } \quad \text{or} \quad 73.5 \sqrt{7} [/tex]
Step-by-step explanation:
we have a right angle triangle composited in a semi-circle we want to figure out the area of the triangle
in order to do so we need to figure out the adjacent side (height AB)
since the given triangle is a right angle triangle we can consider Pythagoras theorem given by
[tex] \displaystyle {a}^{2} + {b}^{2} = {c}^{2} [/tex]
given that,a=21 and c=28
substitute:
[tex] \displaystyle {21}^{2} + {b}^{2} = {28}^{2} [/tex]
move left hand side expression to right hand side and change its sign:
[tex] \displaystyle {b}^{2} = {28}^{2} - {21}^{2} [/tex]
square root both sides:
[tex] \displaystyle {b}^{} = \sqrt{{28}^{2} - {21}^{2} }[/tex]
use algebraic indentity:
[tex] \rm \displaystyle {b}^{} = \sqrt{({28}^{} + 21) (28 - {21}^{})}[/tex]
simplify:
[tex] \rm \displaystyle {b}^{} = \sqrt{({49}) ( 7)}[/tex]
use redical property:
[tex] \rm \displaystyle {b}^{} = 7 \sqrt{ 7}[/tex]
now to figure out the area we can consider the following formula:
[tex] \displaystyle A_{ \text{triangle}} = \frac{1}{2} bh[/tex]
remember that,h=AB=7√7 and b=BC=21 thus substitute:
[tex] \displaystyle A_{ \text{triangle}} = \frac{1}{2} \times 21 \times 7 \sqrt{7} [/tex]
simplify multiplication:
[tex] \rm \displaystyle A_{ \text{triangle}} = \frac{147 \sqrt{7} }{2 } \quad \text{or} \quad 73.5 \sqrt{7} [/tex]
hence,
the area of the triangle is 194 (approximately)

1a.) Brian borrowed 4 non-fiction books from the library. This was 25% of the
books he checked out. How many books did Brian check out? *
Answer:
Total number of books borrowed= 16
Step-by-step explanation:
Giving the following information:
Number of non-fictions books= 4
Percentage of books borrowed= 25% = 0.25
To calculate the total number of books borrowed, we need to use the following formula:
Total number of books borrowed= 4 / 0.25
Total number of books borrowed= 16

You flip a coin 50 times and get 26 tails. What is the experimental probability of flipping heads? Write your answer as a simplified fraction or a percentage.
Answer:
12/25
Step-by-step explanation:
If you got 26 tails, that means you got 50 - 26 or 24 heads. The experimental probability can be represented by the desirable flips over the total number of flips. We are looking for heads, so the amount of heads is the amount of desirable flips, and the total is 50. From this, we get the fraction 24/50 which simplifies to 12/25.
