Answer:
(0,44)
Step-by-step explanation:
To answer this question, I would start by finding the equation of the second line. You can do that by plugging it into the formula y-y1=m(x-x1). You can take the slope from the first equation, which would be m=-13. So, y-5=-13(x-3). You can simplify that to get y=-13+44. Finally, to get a point, you can plug in almost any value for x and use the value of y to create a point. For example, if you choose x=0, you can get y=44 and the point (0,44)
Answer:
20.33%
Step-by-step explanation:
We have that the mean (m) is equal to 87.5, the standard deviation (sd) 6.25 and the sample size (n) = 12
They ask us for P (x <86)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd / (n ^ 1/2))
We have all these values, replacing we have:
z = (86 - 87.5) / (6.25 / (12 ^ 1/2))
z = -0.83
With the normal distribution table (attached), we have that at that value, the probability is:
P (z <-0.83) = 0.2033
The probability is 20.33%
Distributive property is an algebra property that is used to multiply a single term and two or more terms inside parentheses.
