Answer:
The first step to solve the equation below is to first distribute the 2 to (x+7)
Step-by-step explanation:
2 (x+7) = -4x + 14
2x + 14 = -4x + 14
1.
Chance of finding a bug = 0.35
Chance of not finding a bug = 1 - 0.35 = 0.65
Probability of finding a bug in the first 3 programs =
Probability of not finding a bug in 2 out of the 3 and finding a bug in 1.:
0.65^2 * 0.35 = 0.147 = 0.15
Answer is A.
2.
Probability of heads = 0.50
Probability of tails = 0.50
Probability of heads on the fourth attempt = tails x tails x tails x heads = 0.5 x 0.5 x 0.5 x 0.5 = 0.0625
The answer is B.
It should be C english :)
The answers are option C) segment and option D) ray
<u>Step-by-step explanation</u>:
Line :
- A line has arrow mark in the two ends. So, the diagram is not a line.
Point :
- A point represents particular spot as a small dot. So, the diagram is not a point.
Segment :
- It is a piece of line that has two end points. This part of line is called line segment and it is shown in the picture. option C is correct.
Ray :
- A ray is a line with one endpoint and the other end extends with an arrow mark. So, the option D is also correct.
