Arnoldo needs to write this system in slope-intercept form. Which shows how he could do that?
Jobisdone [24]

Answer:

y =  \frac{3}{2}x - 3

y =  \frac{1}{8} x -  \frac{7}{8}

Step-by-step explanation:

The given system is

3x-2y=6

0.4(20y+15)=x

The slope intercept form is y=mx+c.

For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6

y =  \frac{3}{2}x - 3

For 0.4(20y+15)=x, we expand to get:

8y  + 7 = x

8y= x - 7

Divide through by 8

y =  \frac{1}{8}x -  \frac{7}{8}

Therefore the system in slope-intercept form is:

y =  \frac{3}{2}x - 3

y =  \frac{1}{8}x -  \frac{7}{8}

If a and b are independent events with p(a) = 0.05 and p(b) = 0.65, then the conditional probability p(a |
alukav5142 [94]
Two events are said to be independent when the occurence of one event does not in any way affects the occurence of the other event.

For independent events, the probablilty of event A happening given that event B has happened is given by the probability of event A happening.

i.e. P(a | b) = P(a).

Therefore, given that p(a) = 0.05 and P(b) = 0.65, then p(a | b) = p(a) = 0.05.

The area of circle Z is 64. What is the value of r? r = ____ft
andrezito [222]
Given the circle has a radius of 64, to get the value of the radius,r we shall proceed as follows.
Area=πr^2
Thus;
64=πr^2
64/π=r^2
r^2=20.3718
r=sqrt(20.3718)
r=4.5135
Therefore the length of radius,r=4.5135 units
