Answer:

the slope is \frac{7}{4}

Step-by-step explanation:

Given: 4y - 7x = 10; solve y

4y - 7x = 10; add 7x to both sides to isolate the 4y variable

4y = 7x + 10; now divide by 4

y = \frac{7}{4}x + \frac{10}{4}; reduce the fraction

y = \frac{7}{4}x + \frac{5}{2}; the slope is

A set of X and Y scores has a regression equation with a slope of b = 4. If the mean for the X values is MX = 2 and the mean for
Rom4ik [11]

Answer:

-2

Step-by-step explanation:

In a linear regression model we have the equation Y = b_{1}X + b_{0} that relates X and Y, where b_{1} is the estimator of the slope and b_{0} is the estimator of the Y-intercept. The coefficients b_{1} and b_{0} can be estimated with the equations:

b_{1} = \frac{S_{xy}}{{S^{2}}_{x}}

b_{0} = MY-b_{1}MX. Thus,

b_{0} = 6 - (4)(2) = -2

Give a rule of the​ piecewise-defined function. Give the domain and the range.
dimulka [17.4K]

Answer:

Hello your question is incomplete below is the complete question

option B is correct  

f(x) = 1 if x ≤ 0

       -2 if x > 0

Step-by-step explanation:

The Rule of the piece-wise-defined function is :

from the given figure attached it can be seen that as : x ≤ 0 , y = 1

while for x > 0 , y = -2

therefore option B is correct  

f(x) = 1 if x ≤ 0

       -2 if x > 0
