Angelina_Jolie [31]
To evaluate the probability that a randomly selected day will be between 28 and 34 minutes we proceed as follows:
P(28<x<34)
First we evaluate the z-score for the above values:
z=(x-σ)/μ
μ=26.7
σ=5.1

when:
x=28
z=(28-26.7)/5.1
z=0.26
P(z<0.26)=0.6026

when x=34
z=(34-26.7)/5.1
z=1.43
P(z<1.43)=0.9236
hence:
P(28<x<34)=0.9236-0.6026=0.321~32.1%

What is the y-intercept of the equation 8x – 3y = 24?
Levart [38]

Answer:

-8

Step-by-step explanation:

Create this equation into a y=mx+b form

8x-3y=24

-8x       -8x           -8 to solve for -3y

-3y=-8x+24

----    ---   ---              divide by -3 to leave y by itself

-3      -3   -3

y= 8

    --- x-8

     3

y intercept is -8

Find the equation of the line shown below...
vovangra [49]

Answer:

y = -1/4x+2

Step-by-step explanation:

We can find the slope by finding two points on the line, and doing (y1-y2) ÷ (x1-x2). The two points I chose were (0,2), and (4,1). We can plug this into the equation to get (2-1) ÷ (0-4), to get -1/4, which is our slope. We can see on the graph, that the line intersects with the y axis when the y coordinate is 2, making the y-int 2.
