"world" power ???

Don't you mean "what is 7 to the 4th power?"

It's (7)(7)(7)(7) = (49)(49), or approx. 2,500. Multiply out 49(49) for the exact answer.

Use linear regression to find the equation for the linear function that best fits this data. Round both numbers to two decimal p

natta225 [31]

Answer:

The equation of the linear function that best fits the data is,

<em>y</em> = 18.66<em>x</em> + 66.87.

Step-by-step explanation:

The line of best is of the form: <em>y</em> = <em>mx</em> + <em>b</em>.

Here, <em>m</em> = slope of the line and <em>b</em> = intercept.

The formula to compute the intercept and slope are:

$b=\frac{\sum Y.\sum X^{2}-\sum X.\sum XY}{n.\sum X^{2}-(\sum X)^{2}}$

$m=\frac{n.\sum XY-\sum X.\sum Y}{n.\sum X^{2}-(\sum X)^{2}}$

Consider the table below for the values of <em>∑ X, ∑ Y, ∑ X² </em>and <em>∑ XY</em>.

Compute the value of intercept and slope as follows:

$b=\frac{\sum Y.\sum X^{2}-\sum X.\sum XY}{n.\sum X^{2}-(\sum X)^{2}}=\frac{(793\times91)-(21\times3102)}{(6\times91)-(21)^{2}} =66.867$

$m=\frac{n.\sum XY-\sum X.\sum Y}{n.\sum X^{2}-(\sum X)^{2}}=\frac{(6\times3102)-(21\times793)}{(6\times91)- (21)^{2}} =18.657$

The line of best fit is:

$y=mx+b\\y=18.657x+66.867\\y=18.66x+66.87$

Thus, the equation of the linear function that best fits the data is <em>y</em> = 18.66<em>x</em> + 66.87.

Marcellus has a pitcher that contained 5/8 gallon limeade. Marcellus drank 1/4 gallon of the limeade, and Marcy drank 1/8 gallon

mash [69]

Answer:

2/5

Step-by-step explanation:

Given Marcellus drank 1/4 gallon of the limeade and Marcy drank 1/8 gallon of the limeade

Given that only 5/8 portion of the pitcher contains limeade

Total amount drunk = amount drunk by Marcellus + amount drunk by Marcy

Total amount drunk = $\frac{1}{4} +\frac{1}{8}$ = $\frac{3}{8}$

The amount of Limeade remained = The amount initially - the amount drunk

The amount remained = $\frac{5}{8} -\frac{3}{8}$ = $\frac{1}{4}$

Fractional part = amount remained / amount initially = $\frac{\frac{1}{4} }{\frac{5}{8} }$ = $\frac{2}{5}$
