Are the graphs of the lines in the pair parallel? Explain.

1 answer:

6 0

So you gotta change the second one to slope int form and it will become -3y=18x-54 which means that it's A because parallel lines can't be parallel if the slopes are different. (pretty sure this is right but who knows)

1. a²+b²=c²
a=6²=36
b=x²
c=15²=225
x=√189 feet deep (the square root of 189)
2. a²+b²=c²
a=3²=9
b=x²
c=5²=25
x=√16=4

Hope that helped

A study shows that 84% of the population of all calculus students consider calculus an exciting subject. Suppose 29 students ar

ratelena [41]

Answer:

P = 0.041553

Step-by-step explanation:

Probability that a student considers calculus exciting. = 0.84

Probability that a student finds calculus not exciting = 0.16

This is a binomial experiment.

p = 0.84 and n = 29

The probability of observing 28 or more of the students who consider calculus to be an exciting subject in our sample of 29 is given by:

$\left(\begin{array}{ccc}29\\28\end{array}\right) .0.84^{28} .0.16^{1}+\left(\begin{array}{ccc}29\\29\end{array}\right) .0.84^{29} .0.16^{0}$

P = 0.041553
