Answer:
y + 4 = -3(x + 1)
Step-by-step explanation:
point-slope form : y - y2 = m (x - x2)
In this case m = -3 and x2 = -1, y2 = -4
So
The equation in point-slope form
y + 4 = -3(x + 1)

and

Seems like thier perimeters are equal.
Answer:
a) 0.6032
b)
Lower limit: 0.48
Upper limit: 0.72
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
Question a:
In a random sample of 63 professional actors, it was found that 38 were extroverts.
We use this to find the sample proportion, which is the point estimate for p. So

Question b:
Sample of 63 means that 
95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

Rounding to two decimal places:
Lower limit: 0.48
Upper limit: 0.72
Answer:
no
Step-by-step explanation:
there has to be a common value that they are all multiplied by
