The 6 AM temperatures for four consecutive days in town of Lincoln were -12.1°C, -7.8°C, -14.3°C, and -7.2°C. What was the average 6 AM temperature for the four days

- 10.35°C

Step-by-step explanation:

Given that :

Temperature at 6 AM for four consecutive days :

X : -12.1°C, -7.8°C, -14.3°C, and -7.2°C

The average temperature :

ΣX / n

n = sample size = number of days = 4

[(-12.1) + (-7.8) + (-14.3) + (-7.2)] / 4

= - 41.4 / 4

= - 10.35°C

Hence, the average 6 AM temperature for the four days is - 10.35°C

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
