Give the person above me brainlyest for helping!
Step-by-step explanation:
The coefficient of correlation for the given data of x and y is 0.78.
x and y have a strong, positive correlation
What is Coefficient of Correlation?
A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables. In other words, it reflects how similar the measurements of two or more variables are across a dataset.
Here, given values of x and y
x 1 2 3 4 5 6
y 3 4 9 7 2 18
xy 3 8 27 28 10 108
x² 1 4 9 16 25 36
y² 9 16 81 49 4 324
∑x = 21, ∑y = 43, ∑xy = 194, ∑x² = 91, ∑y² = 483, n = 6
Now, Correlation between x and y
r = (n∑xy - ∑x.∑y)/ √[{n∑x²- (∑x)²}{n∑y² - (∑y)²}]
r = ( 6 X 194 - 21 X 43 ) / √[ {6 X 91 - (21)²}{ 6 X 483 - (43)²}]
r = ( 1164 - 903) / √( 546 - 441)(2898 - 1849)
r = 261 / √ 105 X 1049
r = 261 / √110145
r = 261 / 331.88
r = 0.78
Thus, The coefficient of correlation for the given data of x and y is 0.78.
x and y have a strong, positive correlation

A family has 4 boys and the family determines this as unusual.
Design a simulation involving a coin that could be used to the estimate the probability of having four boys.
From the simulation, explain if the family's claim of having 4 boys is unusual is correct.
Answers
Answer: (1 in 16 chance)
Step-by-step explanation: make in a paper a line that becomes 2 lines and keep doing it until you have 16 lines and every line you do like 1boy 0girl and 0boy 1girl and keep doing it and you will have 1 of 16 being 4boys
The probability of having four boys is 1/6.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
A family has 4 boys and the family determines this as unusual.
Design a simulation involving a coin that could be used to the estimate the probability of having four boys.
Throw a coin at randon 4 times we regrade face up is a boy.
Face down is girls.
There are 4 boys means number of wins that face up is 4.
The probability of having four boys is;
[tex]\rm Probability= \left(\dfrac{1}{2} \right )^4\\\\Probability =\dfrac{1^2}{2^4}\\\\Probability =\dfrac{1}{16}\\[/tex]
Hence, the probability of having four boys is 1/6.

Step-by-step explanation:
Answer:
360 in²
Explanation:
The given figure is a wedge.
If you need the surface area then,
Height×Base=(9×12)=108 in²
2nd Base×Length=(3×15)=45 in²
Height×2nd base=(9×3)=27 in²
Base×Length=(12×15)=180 in²
Then add all of them=(108+45+27+180)in²
=360 in²
∴The area of the wedge is 360 in²

Here is the graph of a function showing the amount of money remaining on a subway fare card as a function of the number of rides taken.
What is the output of the function when the input is 10? ____
What is the input to the function when the output is 5? _____
Answers
Answer:
10 is 14 (10,14) and 5 is 16 (5,16)
Step-by-step explanation:
the output is the same as the x value or the number of rides taken. The y is the amount on the card, or how much money is left of the card. So to solve this question, you want to follow the x-axis (the bottom numbers) til you reach the output you need then match that with the input by looking directly left on the chart. Hopes this helps!

Answers
1 billion is 1,000,000,000
X value represents seconds:
1,000,000,000 = 20,334,000x
To solve divide 1,000,000,000 by 20,334,000.
x = 49.179
Round up since the value is time.
50 seconds
So it would take 50 seconds to make 1 billion if you make 20.334 million a secong

Which term can be used in the blank of [tex]36x^3-22x^2 -[/tex] _____ so that the greatest common factor of the resulting polynomial is 2x? Select TWO options:
A: 2
B: 4xy
C: 12x
D: 24
E: 44y
Answers
Answer:
The missing term is 4x
The missing term is 16x
Step-by-step explanation:
* Lets explain how to solve the problem
- The polynomial is 36x³ - 22x² - ..............
- We need to find the missing term such that the greatest common
factor of the resulting polynomial is 2x
The greatest power of x is 3, and there is another term with x²,
then the missing term must have x to have a greatest common
factor of the variable = x
The coefficients of the given terms are 36 and 22 , the greatest
common factor of them is 2 so we must to chose the coefficient
of the missing term with a factor 2
# Option 1:
the missing term is 4x
36x³ - 22x² - 4x = 2x(18x² - 11x - 2)
* The missing term is 4x
# Option 2:
the missing term is 16x
36x³ - 22x² - 16x = 2x(18x² - 11x - 8)
* The missing term is 16x
