Answer:
The third image is the correct answer.
Step-by-step explanation:
33.3 repeating percent
You set up a proportion
6/18 = x/100
100x6= 600
600÷18 = 33.3 repeating
Honestly photo math is the way to go but I got r= 17/13
Answer:
Step-by-step explanation:
a)General least square regression line is ,
Where,a=intercept. b= slope
To get line just find values of a and b.
Use Excel to find values.
First enter values of variable "age" that is y in the column A that is A1to A5 and values of variable "height" in the column B, B1 to B5.
Then for value of a use functufuas ,
=INTERCEPT(A1:A5,B1:B5)
Then hit enter ,therefore a=20.4595
For b use function as. =SLOPE(A1:A5,B1:B5)
Then hit enter.therefore b=0.3738
Therefore equation of least square regression line is
Y=20.4595+(0.3738*x)
b) to predict height at age 21 years or 252 month just put value of x=252 in the above equation.
Y=20.4595+(0.3738+252)
Y=20.4595+94.1976
Y=114.6571
Conclusion: height will be 114.6571 inches when age change by 1 unit.
Answer:
is the slope intercept form for 16x+9y=40
Step-by-step explanation:
Here, the given equation is 16 x + 9 y = 40
Now, the slope intercept form of an equation is y = mx + c,
here m = slope of the equation, b = y - intercept
So, now 16x + 9y = 40 on simplification gives
9y = 40 - 16x
or ![y = \frac{40 - 16x}{9} = \frac{40}{9} - \frac{16x}{9}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B40%20-%2016x%7D%7B9%7D%20%20%3D%20%5Cfrac%7B40%7D%7B9%7D%20%20%20-%20%5Cfrac%7B16x%7D%7B9%7D)
or,
is the slope intercept form of the given equation.
Here, m = (-16/9) and y- intercept = 40/9
