Answer:
or 30%
Step-by-step explanation:
We will divide the wanted outcomes by the possible outcomes.
![\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{number of prime number}}{\text{number of numbers 1 through 50}} =\frac{15}{50}=\frac{3}{10}\;\; \text{or 30\%}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B%5Ctext%7Bwanted%20outcomes%7D%7D%7B%5Ctext%7Bpossible%20outcomes%7D%7D%20%3D%5Cfrac%7B%5Ctext%7Bnumber%20of%20prime%20number%7D%7D%7B%5Ctext%7Bnumber%20of%20numbers%201%20through%2050%7D%7D%20%3D%5Cfrac%7B15%7D%7B50%7D%3D%5Cfrac%7B3%7D%7B10%7D%5C%3B%5C%3B%20%5Ctext%7Bor%2030%5C%25%7D)
The prime numbers from one through fifty are; 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, and 47.
-> This is 15 numbers
The slope-intercept form:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
m - slope
b - y-intercept
We have the equation in standard form.
<em>subtract 2x from both sides</em>
<em>divide both sides by (-3)</em>
![y=\dfrac{2}{3}x-2](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B2%7D%7B3%7Dx-2)
I think it's 1,876,480 but I'm not sure
The x-intercept will be the value of x when y=0. The solutions to (x+1)(x+2)=0 are -1 and -2 since we can substitute them in to have one of the values in parentheses equal to zero, so our x-intercepts are (-1, 0) and (-2, 0). The y-intercept is the value of y when x=0, or (0+1)(0+2)=2. Therefore, the y-intercept is (0, 2).
