The following set of data represents the number of votes for the winner of prom queen over the past several years: 87 94 95 70 75 59 53 82 82 68. Find the median number of votes cast
Answer:78.5
Step-by-step explanation:
the median is the middle digit so with 10 different numbers it would be the 5th or sixth number
but you have to first have them in least to greatest order
53,59,68,70,75,82,82,87,94,95
5th+6th/2
75+82= 157
157/2
78.5

Answer:
[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]
Step-by-step explanation:
Given
[tex]S = \{1,2,3,4,5\}[/tex]
[tex]n(S) = 5[/tex]
Required
[tex]P(x > 1\ and\ x < 2)[/tex]
[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:
[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]
Since it is a probability with replacement, we have:
[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]
For x > 1, we have:
[tex]x > 1 = \{2,3,4,5\}\\[/tex]
[tex]n(x > 1) = 4[/tex]
For x < 2, we have:
[tex]x < 2 = \{1\}[/tex]
[tex]n(x < 2) = 1[/tex]
[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]
becomes
[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]
[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]
find the value of x in given expression !!

The data set represents the ages of students, in years, attending a robotics club meeting. What is the median age of the students in the club?
13, 15, 12, 12, 11, 16, 11, 13, 14, 12
Answer:
12.5
Step-by-step explanation:
put them in order from least to greatest: 11, 11, 12, 12, 12, 13, 13, 14, 15, 16
the middle is 12 and 13 so you do 12+13 then divide by 2
to get 12.5

what are the next two terms in the sequence?: 1, -2, 4, -8
Answer:
16 and -32Step-by-step explanation:
-2÷1 = -2
4÷(-2) = -2
-8:4 = -2
So this is a geometric sequence with a common ratio of -2
Therefore:
the 5th term: -8×(-2) = 16
the 6th term: 16×(-2) = -32

find the value of x in the picture
Answer:
x = 9
Step-by-step explanation:
5x+4 = 49
subtract 4 from both sides
5x = 45
divide both sides by 5
x = 9
Answer:
x = 9
Step-by-step explanation:
49 degrees and (5x + 4) are vertical lines, meaning they are congruent.
We can make an equation with this information:
(5x + 4) = 49
-4 -4
5x = 45
/5 /5
x = 9
I really need help lol...you get 81 POINTS!!!!!!!!!!!!!!!!!!
Answer:
area = 82 cm²
Step-by-step explanation:
The figure comprises a trapezoid, a triangle and a square.
Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.
Area of square : (side)²
= (2)²
= 4 cm²
Area of triangle : ½ × b × h
= ½ × 3 × 12
= 3 × 6
= 18 cm²
Area of trapezoid : ½ × (a + b) × h
= ½ × (5+5) × 12
= ½ × 10 × 12
= 5 × 12
= 60 cm²
Now, area of the composite figure :
= 4 + 18 + 60
= 22 + 60
= 82 cm²
Answer:
82 cm²Step-by-step explanation:
If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.
Its area is:
A = (5 + 8)*12/2 = 78 cm²Add the area of the square with sides of 2 cm:
A = 2*2 = 4 cm²Total area is:
A = 78 + 4 = 82 cm²ANYONE PLS HELP ASAP!!

What number should Rihanna use for the height of the parallelogram if she uses 28 inches for the base
Answer:
[tex]Height = 7in[/tex]
Step-by-step explanation:
Given
See attachment for parallelogram
[tex]Base = 28in[/tex]
Required
What is the height?
The opposite sides of a parallelogram are equal and the height is the distance between the parallel sides.
From the question, we have:
[tex]Base = 28in[/tex]
Also from the question, the difference between the two parallel sides is 7in.
Hence, the height of the parallelogram in 7in

Find the area and the perimeter of the figure below. The figure is composed of small
squares with a side-length of 1 unit and curves that are an arc of a circle.
our answer
Answer:
11.28 units squared
Step-by-step explanation:
Area of a circle is
[tex]\pi {r}^{2} [/tex]
each square has an area of 1
There are four semi-circles, which make two complete circles.
the area of the 5 squares plus the area of the two circles equals the total area.
5 + 2(3.14) = 11.28

The value of a car with an initial purchase price of $12,250 depreciates by 11 percent per year
Answer:
It is decay because the value of the car keeps falling.
for example, the value next year, would be 12250 x (100% - 11%) = $10,902.50
If it were a growth, the value would increase yearly
12250 x (0.89)^time
Step-by-step explanation:
the equation to represent exponential decay = Amount x ( 1 - rate)^time
