PLEASE HELP IM STUCK ONLY 3 MORE QUESTIJONS

Mathematics
1 answer:
True [87]2 years ago
3 0

Answer:

y = - 2x + 8

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = \frac{1}{2} x - 9 ← is in slope- intercept form

with m = \frac{1}{2}

given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{\frac{1}{2} } = - 2

y = - 2x + c ← is the partial equation

to find c substitute (3, 2 ) into the partial equation

2 = - 6 + c ⇒ c = 2 + 6 = 8

y = - 2x + 8 ← equation of perpendicular line

10. Answer True or False for the following statements. If false, justify what would make the statement true. a. If the least-squ
Free_Kalibri [48]

Answer:

a) TRUE

b) FALSE

c)  FALSE

d) TRUE

e) FALSE

Step-by-step explanation:

a)

TRUE because the slope of the correlation line is 2  and this is the rate of change of y respect to x

b)

FALSE

The correlation coefficient r is always between -1 and 1, so it can never be greater than one

c)

FALSE

A student might expect that there is a positive correlation between the age of their laptop and its resale value only if after collecting a large enough sample of data that relates age of the student and price of resale of their laptop, he or she finds that there is a positive correlation coefficient r>0

d)

TRUE

If there is a positive correlation, then the greater the x, the greater the y

e)

FALSE

If there is no correlation between the independent and dependent variables, then the value of the correlation coefficient must be 0.
