Answer:

The probability of not drawing a black marble is 8/10 and the probability of drawing a red marble is 3/10.

Step-by-step explanation:

There are 10 marbles altogether, and 8 of them are not black marbles, and only 3 of them are red.

Since you are not allowed to draw a black marble, then you have only 7 ways to draw either a blue or a red marble. The sum of all marbles is 10. So the probability of not drawing a black marble is 7/10 and the probability of drawing a red marble is 2/10 or 1/5.

Endpoints of segment MN have coordinates (0, 0), (5, 1). The endpoints of segment AB have coordinates (1 1/2 , 2 1/4 ) and (−2 1
Zielflug [23.3K]

Answer:

k=21

Step-by-step explanation:

Find the slope of MN which is 1/5 (use the slope formula)

Use the slope formula for AB using k as y_2

Substitute and you get k=21

21-2.25/-2.25-1.5=-5

The lines are perpendicular because the slopes are the negative reciprocal of one another.

Answer:

x = 3

Step-by-step explanation:

{5}^{2x}  \ast {5}^{3}  =  {5}^{9}  \\  {5}^{2x + 3}  =  {5}^{9}  \\ 2x + 3 = 9 \\ (bases \: are \: equal \: so \: exponents \: will \: also \: \\  be \: equal) \\ 2x = 9 - 3 \\ 2x = 6 \\ x =  \frac{6}{2}  \\  \huge \red { \boxed{x = 3}}
