Step-by-step explanation:
1) Find the Mean of all the numbers.
3+4+5+7+10+12+15=56
56/7=8 mean is 8
Now We Calculate Standard Deviation:
S=[tex]\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}[/tex]
You take each number from the problem i.e 3,4,5...
and then you subtract the mean from it and then square it.
S=[tex]\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}[/tex]
S=[tex]\sqrt{25+16+9+1+4+16+49}[/tex]
S=[tex]\sqrt{120}[/tex]
S=[tex]\sqrt{120}/7[/tex]
7 is the amount of data units given in the problem.
120/7=17.1428571429
[tex]\sqrt{17.1428571429}[/tex] =4.1403933560541

22. The area of a triangle can be represented by the expression 14x^5 + 63x^2. If the base is 7x^2, write
an expression to represent its height.
Answers
Answer:
h = 4x ^ 3 + 18
Step-by-step explanation:
The first thing you should know for this case is that the area of a triangle is given by:
A = (1/2) * (b) * (h)
Where,
b: base.
h: height.
Clearing the height we have:
h = ((2) * (A)) / (b)
Substituting the values
h = ((2) * (14x ^ 5 + 63x ^ 2)) / (7x ^ 2)
Simplifying the expression:
h = ((2) * (2x ^ 3 + 9))
h = 4x ^ 3 + 18
answer
an expression to represent its height is
h = 4x ^ 3 + 18

Step-by-step explanation:
The area of the parallelogram is A = 140 units²
What is a Parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
The sum of angles of a parallelogram is 360°
The four types are parallelograms, squares, rectangles, and rhombuses
Properties of Parallelogram
Opposite sides are parallel
Opposite sides are congruent
Opposite angles are congruent.
Same-Side interior angles (consecutive angles) are supplementary
Each diagonal of a parallelogram separates it into two congruent triangles
The diagonals of a parallelogram bisect each other
Given data ,
Let the area of the parallelogram be represented as A
Now , the value of A is
Let the height of the parallelogram be h = 14 units
And , base of the parallelogram b = x + y = 10 units
So , A = b x h
On simplifying , we get
The area of parallelogram A = 10 x 14 = 140 units²
Therefore , the value of A is 140 units²
Hence , the area of the parallelogram is 140 units²

A spinner has three unusual sections: red, yellow, and blue.. The table shows the results of Nolan’s spins. Find the probability of landing on each color.
Answers
Answers:
Red = 1/3Yellow = 7/15Blue = 1/5====================================================
Explanation:
Add up all the frequencies in the table to see that there are 120+168+72 = 360 spins total.
Of those 360 spins, 120 of them land on red. The probability of landing on red is 120/360 = (120*1)/(120*3) = 1/3Since 168 land on yellow, this means the probability of landing on yellow is 168/360 = (24*7)/(24*15) = 7/15Lastly, we have 72 occurrences of blue out of 360 total spins. The probability of landing on blue is 72/360 = (72*1)/(72*5) = 1/5Kylie and Matt are driving out of town, leaving from the same house in
different cars. Matt drives at a rate of 40 miles per hour. Matt drives 50
miles before Kylie begins traveling. Kylie drives at a rate of 50 miles per
hour. .
Answers
Answer:
They will meet in 5 hours.
Step-by-step explanation:
This question should ask how long until they meet.
Matt drives at a rate of 40 miles per hour. Matt drives 50 miles before Kylie begins traveling.
So the total distance for Matt is given by:
[tex]M(t) = 40t + 50[/tex]
Kylie drives at a rate of 50 miles per hour.
When he starts(at position 0), Matt will be already at 50. So Kylie's equation is given by:
[tex]K(t) = 50t[/tex]
How many hours until they meet?
This is t for which:
[tex]K(t) = M(t)[/tex]
So
[tex]50t = 40t + 50[/tex]
[tex]10t = 50[/tex]
[tex]t = \frac{50}{10}[/tex]
[tex]t = 5[/tex]
They will meet in 5 hours.

(Hint: use the perimeter to find the length of the side)
Answers
Answer: Down Below

3.) A box in the shape of a rectangular prism has a volume of 180 cm". The length is x cm, the
width is (x + 9) cm, and the height is (x – 4) cm. Find the dimensions of the box.
Answers
Answer:
48
Step-by-step explanation:
i am a smart
The dimensions of the box are;
Length = 2.44 cm
Width = 11.44 cm
Height = 1.56 cm
How to find the volume of a right rectangular prism?Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:
[tex]V = a\times b \times c \: \: unit^3[/tex]
Given box in the shape of a rectangular prism has a volume of 180 cm".
The length is x cm, the width is (x + 9) cm, and the height is (x – 4) cm.
Volume = (x + 9) (x – 4) (x)
180 = (x + 9) (x – 4) (x)
180 = (x²+ 9x) (x² – 4x)
x³ + 13x² + 36x - 180 = 0
x = 2.44
Thus, width is (x + 9) cm = 2.44 + 9 = 11.44 cm
The height is (x – 4) cm = 2.44 - 4 = 1.56 cm
