Answer: The slope is 2/3, y=2/3x+1

Step-by-step explanation: The 2 points, (3,3) and (6,5), use the method y2-y/x2-x1. Then you find the slope that way, then use point slope form for the slope intercept form: y-y1=m(x-x1), then substitute and solve to get y=2/3x+1

\bf M(x)=c(0.5)^{\frac{x}{h}}\implies 10=36(0.5)^{\frac{x}{4.9}}\implies \cfrac{10}{36}=0.5^{\frac{x}{4.9}}
\\\\\\
\cfrac{5}{18}=0.5^{\frac{x}{4.9}}\implies log\left( \frac{5}{18} \right)=log\left( 0.5^{\frac{x}{4.9}} \right)
\\\\\\
log\left( \frac{5}{18} \right)={\frac{x}{4.9}}\cdot  log\left( 0.5 \right)\implies 
\cfrac{4.9\cdot  log\left( \frac{5}{18} \right)}{log(0.5)}=x

How many solutions does 2(x-6)+2x=4(x-3) have?
AveGali [126]

Answer:

Infinite

Step-by-step explanation:

2(x-6)+2x=4(x-3) would turn into:

2x-12+2x=4x-12 which would turn into:

4x-12=4x-12 then you could keep going if you wanted:

add 12 to both sides and subtract 4x from both sides:

0=0 (and zero does equal zero so it is unlimited solutions)

You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your d
Trava [24]

Answer:

Following are the solution to this question:

Step-by-step explanation:

For this set, the correlation coefficient is = -0.015.

It shows that financial variables have trust issues. Once a price rises, the other one is decreasing the value of -0,015 shows, that there are several fewer associations in the set of data among x and y and between y values. This interaction also can range between -1 to 1, to 0 being completely unrelated. But you'd never be sure, in this situation, 0.015 is very similar to 0.

It means that your prediction is nothing better than just a wild choice. Its odds of an estimated value being relatively close to the actual result are therefore much smaller as the points are it's hardly the best match.
