Solve using quadratic formula pls show work​
Temka [501]

Answer:

x=\frac{3}{8},\:x=0

Step-by-step explanation:

x_{1,\:2}=\frac{-\left(-3\right)\pm \sqrt{\left(-3\right)^2-4\cdot \:8\cdot \:0}}{2\cdot \:8}

\sqrt{\left(-3\right)^2-4\cdot \:8\cdot \:0}

=\sqrt{3^2-4\cdot \:8\cdot \:0}

\sqrt{3^2}

3

x_{1,\:2}=\frac{-\left(-3\right)\pm \:3}{2\cdot \:8}

Separate the solutions:

x_1=\frac{-\left(-3\right)+3}{2\cdot \:8},\:x_2=\frac{-\left(-3\right)-3}{2\cdot \:8}

x=\frac{3}{8},\:x=0

Suppose that the number of pounds of grapes sold by the Smalltown Co-op grocery store in a day is equally likely to be anywhere
Alex

Answer:

The height of the function for any number of pounds between 0 and 100 is 0.01.

Step-by-step explanation:

As described, the probability density function is a uniform probability density function, between the values 0 and 100 pounds.

To calculate the height h of the probability density function, we can write:

\int\limits^{100}_0 {h} \, dx=1

If we solved this integration and rearrange

\int\limits^{100}_0 {h} \, dx=1\\h*(100-0)=1\\100*h=1\\h=0.01

The value of the height of the probability density function is 0.01 for every value between 0 and 100 pounds.

y= -1x + 3

0 = -1x + 3

x = 3

The point is (3,0)
