Find the x-intercept of the line whose equation is 8x + 2y =4
Alex787 [66]

Answer:

<h2>x - intercept=  1/2</h2>

Step-by-step explanation:

8x + 2y =4\\Substitute ,y for ;0\\8x+2(0)=4\\8x+0=4\\8x=4\\\frac{8x}{8} =\frac{4}{8} x = 1/2\\(\frac{1}{2} , 0) -x-intercept

METHOD 2

(-\frac{c}{a} , 0)\\a = 8\\b = 2\\c = -4\\\frac{-(-4)}{8} \\x-intercept = \frac{4}{8} \\\\x-intercept = \frac{1}{2}\\(1/2 , 0)

The completion times for a job task range from 10.1 minutes to 19.2 minutes and are thought to be uniformly distributed. What is
levacccp [35]

Answer:

The  probability is  P(12.7 <  x  <  16.8 ) =  0.45

Step-by-step explanation:

From the question we are told that

The completion times for a job task range from 10.1 minutes to 19.2 minutes

Generally given that the completion times is uniformly distributed then  the probability that it will require between 12.7 and 16.8 minutes is mathematically represented as

         P(12.7 <  x  <  16.8 ) =  \frac{ 16.8 - 12.7}{ 19.2 -  10.1 }

          P(12.7 <  x  <  16.8 ) =  0.45

What graph represents the function f(x) = 8 1/3^x?
densk [106]

Answer:

B (second graph from left)

Step-by-step explanation:

The function when x=0 will be 1 since any number to the zero exponent is 1. This means only B and D are options.

Because of the fraction, the values will be smaller and have a gentler slope. B is the solution.
