Answer:

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.

Answer:

Parallel lines will continue beside one another forever without ever touching. Perpendicular lines meet at a 90 degree angle forming a T

Write the inequality in slope-intercept form. 10x + 5y < 15

mestny [16]

Solve for y
minus 10x from both sides
5y<-10x+15
divide both sides by 5
y<-2x+3

Answer: Our required probability is 0.167.

Step-by-step explanation:

Since we have given that

n = 15

Probability of success p = 80% = 0.8

Probability of failure q = 20% = 0.2

We need to find the probability that at least fourteen will work.

So, by Binomial distribution, we get that

$P(X\geq 14)=P(X=14)+P(X=15)\\\\P(X\geq 14)=^{15}C_{14}(0.8)^{14}(0.2)+^{15}C_{15}(0.8)^{15}\\\\P(X\geq 14)=0.167$

Hence, our required probability is 0.167.
