graphing tool to organize the data in different scatter plots and found these lines of best fit:
Answers
Answer:
The answer A
Step-by-step explanation:
The average correlation is close to The relationship between the number of men's, x and the number of women's, y bikes sold hence, it is a line of best fit so, option A is correct.
What is a line of fit?A straight line that minimizes the gap between it and some data is called a line of best fit. In a scatter plot containing various data points, a relationship is expressed using the line of best fit.
Given:
The owner of a sporting goods store gathered data about the numbers of men's, women's, and children's bicycles sold each month,
The relationship between the number of men's, x and the number of women's, y bikes sold is molded by the equation, y = 0.95x + 0.83, and the correlation coefficient is 0.791,
The relationship between the number of men's, x, and the number of children, y bikes sold is molded by the equation, y = 0.87x + 0.98, and the correlation coefficient is 0.564,
The relationship between the number of children x and the number of women's bikes sold is molded by the equation, y = 0.73x + 0.91, and the correlation coefficient is 0.945,
As you can see that the average of the correlation coefficient is,
Average = 0.791 + 0.564 + 0.945 / 3
Average = 2.3 / 3
Average = 0.77
Thus, the correlation 0.791 is the line of best fit.

Use mathematical induction to prove the statement is true for all positive integers n. 1^2 + 3^2 + 5^2 + ... + (2n-1)^2 = (n(2n-1)(2n+1))/3)
Answers
Answer:
The statement is true is for any [tex]n\in \mathbb{N}[/tex].
Step-by-step explanation:
First, we check the identity for [tex]n = 1[/tex]:
[tex](2\cdot 1 - 1)^{2} = \frac{2\cdot (2\cdot 1 - 1)\cdot (2\cdot 1 + 1)}{3}[/tex]
[tex]1 = \frac{1\cdot 1\cdot 3}{3}[/tex]
[tex]1 = 1[/tex]
The statement is true for [tex]n = 1[/tex].
Then, we have to check that identity is true for [tex]n = k+1[/tex], under the assumption that [tex]n = k[/tex] is true:
[tex](1^{2}+2^{2}+3^{2}+...+k^{2}) + [2\cdot (k+1)-1]^{2} = \frac{(k+1)\cdot [2\cdot (k+1)-1]\cdot [2\cdot (k+1)+1]}{3}[/tex]
[tex]\frac{k\cdot (2\cdot k -1)\cdot (2\cdot k +1)}{3} +[2\cdot (k+1)-1]^{2} = \frac{(k+1)\cdot [2\cdot (k+1)-1]\cdot [2\cdot (k+1)+1]}{3}[/tex]
[tex]\frac{k\cdot (2\cdot k -1)\cdot (2\cdot k +1)+3\cdot [2\cdot (k+1)-1]^{2}}{3} = \frac{(k+1)\cdot [2\cdot (k+1)-1]\cdot [2\cdot (k+1)+1]}{3}[/tex]
[tex]k\cdot (2\cdot k -1)\cdot (2\cdot k +1)+3\cdot (2\cdot k +1)^{2} = (k+1)\cdot (2\cdot k +1)\cdot (2\cdot k +3)[/tex]
[tex](2\cdot k +1)\cdot [k\cdot (2\cdot k -1)+3\cdot (2\cdot k +1)] = (k+1) \cdot (2\cdot k +1)\cdot (2\cdot k +3)[/tex]
[tex]k\cdot (2\cdot k - 1)+3\cdot (2\cdot k +1) = (k + 1)\cdot (2\cdot k +3)[/tex]
[tex]2\cdot k^{2}+5\cdot k +3 = (k+1)\cdot (2\cdot k + 3)[/tex]
[tex](k+1)\cdot (2\cdot k + 3) = (k+1)\cdot (2\cdot k + 3)[/tex]
Therefore, the statement is true for any [tex]n\in \mathbb{N}[/tex].

From a standard deck of cards, a 5-card hand is dealt. Calculate the number of hands that contain 4 diamonds and 1 black king
Answers
Answer:
1430
Step-by-step explanation:
Given that a standard deck of cards is 52 cards, we have 13 Diamonds and we need 4 diamonds.
Hence, we have 13C4.
Also, we have 4 kings in a standard deck of cards, and in which we have 2 black kings but we need 1 king.
Hence we have a 2C1
Therefore:
13C4 * 2C1
=> 13! ÷ [4! (13 - 4)!] * 2! ÷ [1! (2-1)!]
=> 13! ÷ [4! (9)!]
=> (1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12 x 13) ÷ [(1 x 2 x 3 x 4) (1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9)]
=> (10 x 11 x 12 x 13) ÷ 24
=> (17160 ÷ 24) * (24 ÷ 6)
=> 715
2! ÷ [1! (2-1)!]
=> 2
Hence, we have 715 * 2
=> 1430
Hence, in this case, the correct answer to the question is 1430

v/22 - 0.1 = 7.4 what is v?
Answers
Answer:
v = 165
Step-by-step explanation:
v/22 -0.1 = 7.4
v/22 = 7.4+0.1 =7.5
v = 7.5*22
v = 165
Answer:
[tex]v = 165[/tex]
Step by step Explanations:1) Add 0.1 to both sides.
[tex] \frac{v}{22} = 7.4 + 0.1[/tex]
2) Simplify 7.4 + 0.1 to 7.5.
[tex] \frac{v}{22} = 7.5[/tex]
3) Multiply both sides by 22.
[tex]v = 7.5 \times 22[/tex]
4) Simplify 7.4 × 22 to 165.
[tex]v = 165[/tex]
Therefor, the answer is v = 165.

Q3. In a hydraulic lift, a 1400 N force is applied to a 0.5 m2 piston. Calculate the minimum surface area of the large piston to lift 5000 N.
Answers
Answer:
1.8m^2 approx
Step-by-step explanation:
Given data
P1= 1400N
A1=0.5m^2
P2=5000 N
A2=??
Let us apply the formula to calculate the Area A2
P1/A1= P2/A2
substitute
1400/0.5= 5000/A2
cross multiply
1400*A2= 5000*0.5
1400*A2= 2500
A2= 2500/1400
A2= 1.78
Hence the Area is 1.8m^2 approx

Find the center and radius of this circle
We have the equation
x² + y² -2x - 10y + 17 = 0
We collect like terms
x² - 2x + y² - 10y = -17
x² - 2x + (-2/2)² + y² - 10y + (-10/2)² = -17 + (-2/2)² + (-10/2)²
The center of the circle is point: C=(1,5).

Brian rolls a fair dice 12 times. How many times would Brian expect to roll a number greater than 4?
Answers
Brian is expected to roll a number greater than 4, 4 times
How to determine the expected row?In a fair die, we have:
Faces = 6
Faces greater than 4 = 2 i.e. 5 and 6
So, the probability to roll a number greater than 4 is:
p = 2/6
When the dice is rolled 12 times, the expected value is:
Expected = 2/6 * 12
Evaluate
Expected = 4
Hence, Brian is expected to roll a number greater than 4, 4 times

A skyrocket is launched from a 30–foot-high platform, with initial speed 300 ft/s. If the polynomial −16t2 + 300t + 30 gives the height that the rocket will rise in t seconds, how high will a rocket with a 2–second fuse rise? The rocket will rise feet.
Answers
Answer:
566 ft
Step-by-step explanation:
Given the polynomial equation
-16t² + 300t + 30 = 0
We're asked to find how high the rocket would rise in a 2 second fuse rise. This is a simple instruction that can be obtained by setting the unknown, t, in the equation to 2. Doing this, we have
-16 * 2² + 300 * 2 + 30
-16 * 4 + 600 + 30
-64 + 630 = 566 ft
Then, we can therefore conclude that the rocket will rise high up to a distance of 566 ft

Answers
As you know, a cube has 6 faces, and each face is a square, and the 6 faces are equal.
then, the total surface area of the cube is equal to 6 times the surface area of one of the faces:
6*f = 600 in^2
then the surface area of one face is:
f = (600/6) in^2 = 100 in^2
Then the correct option is D
