Iterations question please help
nataly862011 [7]

Answer:

option d

{ 4, 8 , 16 , 32 }

Step-by-step explanation:

Given in the question a function

f(x) = 2x

initial valuex_{0}=2

First iteration

f(2) = 2(2)

     = 4

x_{1}=4

Second iteration

f(4) = 2(4)

     = 8

x_{2)=8

Third iteration

f(8) = 2(8)

     = 16

x_{3)=16

fourth iteration

f(8) = 2(16)

     = 32

x_{4}=32

Please helpppppp!!!!!
azamat
Let they meet after second car travels for x hours'
let v be the speed  of second car and V be speed of first car.
Then time taken by first car=x+2
V(x+2)=vx (distance covered is same.)
\frac{v}{V} = \frac{x+2}{x} 
subtract 1 from both sides
 \frac{v-V}{V} = \frac{2}{x} 
v-V= \frac{2V}{x}

VikaD [51]

Answer:

1,172.3 cm³

Step-by-step explanation:

Find the volume of one rod, then divide the total volume of steel used by the volume of one rod.  The volume of one rod is

V = (πd²/4)h

d = 4 cm

h = 20 cm

Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V.  If the result is not an integer, then round down.

Add

20 + 4 = 24

Then

28,134.4 ÷ 24 = 1172.26

Rounded to the nearest 0.1 or  the Tenths Place = 1,172.3

Therefore, 1,172.3 rods will be made per hour.

The Correlation Coefficient for a relationship is - 0.95. What percentage of the dependent variable in the correlation is due pu
seropon [69]

Answer:

The unexplained variance would be 100-90.25 % = 9.75. And that correspond to the percentage of the dependent variable in the correlation is due purely to chance

Step-by-step explanation:

Previous concepts

Pearson correlation coefficient(r), "measures a linear dependence between two variables (x and y). Its a parametric correlation test because it depends to the distribution of the data. And other assumption is that the variables x and y needs to follow a normal distribution".

In order to calculate the correlation coefficient we can use this formula:  

r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}  

On this case we got that r =-0.95

In order to find the % of variance explained by the model we need to calculate the determination coefficient given by:

R^2 = (-0.95)^2 = 0.9025

And that means this : "90.25% of the variation of y is explained by the variation in x"

So then the unexplained variance would be 100-90.25 % = 9.75. And that correspond to the percentage of the dependent variable in the correlation is due purely to chance
