Answer:

e=20

Step-by-step explanation:

Given there is a scatter plot.

A point on it is (10,7)

The regression line y' = -x-3

We have regression line giving estimate for given value of x

When x=10, actual value of y

= y observed = 7 (given)

As per regression line estimate

y = -10-x = -13

Difference between y estimate and actual y = 7-(-13)

=20

Work out m and c for the line: 3 y + 6 x = − 3

Usimov [2.4K]

Answer:

m is -2 and c is -1

Step-by-step explanation:

• Let's first phrase out the general equation of a line

${ \rm{y = mx + c}}$

m is the slope
c is the y-intercept

[ remember that a general line equation must be in slope - intercept form as shown above ]

• from our question, we are given the equation;

${ \rm{3y + 6x = - 3}}$

• let's make y the subject in order to make the equation in slope - intercept format.

→ remember to apply "subject making knowledge"

${ \rm{3y = - 3 - 6x}} \\ \\ { \rm{3y = - 6x - 3}} \\ \\ { \rm{ \frac{3y}{3} = \frac{ - 6x}{3} - \frac{3}{3} }} \\ \\ { \boxed{ \rm{y = - 2x - 1}}}$

• The above boxed equation is now a general equation. Let's extract out slope, m and y-intercept, c

${ \rm{m \: \dashrightarrow \: - 2}} \\ \\ { \rm{c \: \dashrightarrow \: - 1}}$

A polynomial is to be constructed that will touch the x axis at most 8 times. What is the minimum degree of the polynomial?

slamgirl [31]

Every degree is a touching point since each root factor is an x intercept

therefor the answer is 8th degree

The function d =

Nuetrik [128]

Answer:

continuous

Step-by-step explanation:

Since the function d=45t can have numbers in between and time is constantly happening, he does not hop, or skip at 1 second, then 5 seconds...he is continuously traveling, so time = 1 sec, 1.1 sec., 1.1000001, 1.000002, etc. time does not stop therefore if you graphed this, you would connect the dots, therefore, it is continuous

Solve the following equation. Then place the correct number in box provided.

Pepsi [2]

x is equal to 0 because 6 is already equal to 6

so there shouldnt be another number unless its 0

0+6=6
