Distribute
8-2t-2=-3t+1

Combine like terms
-2t+6=-3t+1

Add 3t to both sides
t+6=1

Subtract 6 from both sides
t=-5

Final answer: t=-5

Answer:

Step-by-step explanation:

1) Find the Mean of all the numbers.

3+4+5+7+10+12+15=56

56/7=8 mean is 8

Now We Calculate Standard Deviation:

S= $\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}$

You take each number from the problem i.e 3,4,5...

and then you subtract the mean from it and then square it.

S= $\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}$

S= $\sqrt{25+16+9+1+4+16+49}$

S= $\sqrt{120}$

S= $\sqrt{120}/7$

7 is the amount of data units given in the problem.

120/7=17.1428571429

$\sqrt{17.1428571429}$ =4.1403933560541

Nearest hundredth=4.14
