In how many ways can carlos draw a blue or a green marble from a jar containing 30 blue marbles and 6 green marbles?

2 answers:

7 0

Total outcome = 30 + 6 = 36 [ 'cause it's a simple case when observer takes 1 object at a time]

So, option C is your final answer.

Hope this helps!

D) 180 because there are 180 possible combinations for the marbles to be picked out

What is the equation in point-slope form of the line passing through (1, 9) and (−1, 11)?

ololo11 [35]

Point slope form:
$y-y_1=m(x-x_1)$

m=slope
(x1,y1)

First we need to find the slope using the slope formula:
$\frac{y_2-y_1}{x_2-x_1} =slope$

Given the two coordinates:
(1, 9) and (−1, 11)

Plug them into the slope formula:
 $\frac{11-9=2}{-1-1=-2} =slope$
Simplify:
$\frac{2}{-2} =-1$

Now we know that:
m=-1 and the (x1,y1) would be (1, 9)

Now we simply plug in the info:
$y-9=-(x-1)$

Final answer: y − 9 = −(x − 1)

A side of the triangle below has been extended to form an exterior angle of 165º. Find

Arte-miy333 [17]

Answer:

x = 120°

Step-by-step explanation:

the 165 degree obtuse angle forms a straight line with the upper left angle inside the triangle, therefore this angle measures 15 degrees

we know two of the three angle measures so we add all three together to find the unknown angle

x + 15 + 45 = 180

x + 60 = 180

x = 120°
