Answer:

22, 50, 106, 218

Step-by-step explanation:

Using the recursive formula with f(0) = 8

Substitute n = 1, 2, 3, 4 into the recursive formula and evaluate

f(1) = 2f(1-1) + 6 = 2f(0) + 6 = (2 × 8) + 6 = 16 + 6 = 22

f(2) = 2f(1) + 6 = (2 ×× 22) + 6 = 44 + 6 = 50

f(3) = 2f(2) + 6 = (2 × 50) + 6 = 100 + 6 = 106

f(4) = 2f(3) + 6 = (2 × 106) + 6 = 212 + 6 = 218

1/3=7/21, .. What are the means
gayaneshka [121]

Answer:

Equivelant fractions.

Step-by-step explanation:

Ask your self..

How did the 1/3 become 7/21?

Its very simple multiply 1/3's numerator and denominator by 7

So its going to be.. 1 x 7 = 7

3 x 7 = 21

A regression analysis between weight (y in pounds) and height (x in inches) resulted in the following least squares line: ŷ = 13
Lunna [17]

Answer:

y=6x +135

And for this case the interpretation for the slope would be that for every unit that the height in inches increase then the weight in pounds increase 6 units.

For the intercept of 135 represent the amount initial amount of weight for the scale.

Step-by-step explanation:

We assume that they use least squares in order to create the regression equation

For this case we need to calculate the slope with the following formula:

m=\frac{S_{xy}}{S_{xx}}

Where:

S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}

S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}

With these we can find the sums:

And the slope would be:

m=6

The means for x and y are given by:

\bar x= \frac{\sum x_i}{n}

\bar y= \frac{\sum y_i}{n}

And we can find the intercept using this:

b=\bar y -m \bar x

For this case we know that the line adjusted is:

y=6x +135

And for this case the interpretation for the slope would be that for every unit that the height in inches increase then the weight in pounds increase 6 units.

For the intercept of 135 represent the amount initial amount of weight for the scale.
