How do u determine the equation of the line through each pair of points in slope-intercept form (y=mx+b). (3,0) and (2,4) (-6,3)

steposvetlana [31]

Answer:

Y =-4X +12

Y =-0.625X -0.75

Step-by-step explanation:

(3,0) and (2,4)....

x1 y1 x2 y2

3 0 2 4

(Y2-Y1) (4)-(0)= 4 ΔY 4

(X2-X1) (2)-(3)= -1 ΔX -1

slope= -4

B= 12

Y =-4X +12

~~~~~~~~~~~~~~~~~

(-6,3) and (2,-2)

x1 y1 x2 y2

-6 3 2 -2

(Y2-Y1) (-2)-(3)= -5 ΔY -5

(X2-X1) (2)-(-6)= 8 ΔX 8

slope= - 5/8

B= - 3/4

Y =-0.625X -0.75

If 60% of the students in your class like Burger King, how many students are in your class if 15 students like Burger King?

zloy xaker [14]

Answer:

Step-by-step explanation:

Let x be the number of students in the class

15 is 60% of x

60% of x can be written as 0.6x

15 = 0.6x

Divide by 0.6 on both sides

25 = x

There are 25 students in the class

Hope this helps :)

A Rasmussen Reports survey of 1,000 US adults found that 42% believe raising the minimum wage will help the economy. Construct a

Answer:

(0.3798, 0.4602)

Step-by-step explanation:

Let p be the true proportion of US adults who believe raising the minimum wage will help the economy. A point estimate for p is $\hat{p}=0.42$ and a good aproximation (because we have a large sample) for the standard deviation of $\hat{p}$ is $\sqrt{\hat{p}(1-\hat{p})/n}=\sqrt{0.42(0.58)/1000}=0.0156$ . Therefore, a 99% confidence interval for p is given by $\hat{p}\pm z_{\alpha/2}\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}$ where $\alpha=0.01$ and $z_{\alpha/2}$ is the $\alpha/2$ th quantile of the standard normal distribution, so we have, $0.42\pm z_{0.005}0.0156$ , i.e., $0.42\pm(-2.5758)(0.0156)$ or equivalently (0.3798, 0.4602).
