Twenty-four students took a test. Fourteen students earned an A and 10 students earned a B. A student will be randomly chosen.

Alex_Xolod [135]

The probability of a student that earned an A on the test is 7/12.

To get a fraction like this, you put the number of students on the left, or the top and the number of students total on the right, or bottom. Then, you simplify your answer. This brings us to 7/12. You cannot simplify any further because the fraction includes a prime number.

I hope this helps!

X^2 -50x+456=0 solve this algebraiclly find x

bagirrra123 [75]

Answer:

$x=-406$

Step-by-step explanation:

$x^2-50x+456=0$

$x^2-50x=-456$

This is because we subtract 456 from each side.

$x-50=-456$

We then divide the whole equation by <em>x</em> .

$x=-406$

Adding 50 to both sides gives us <em>x</em> by itself, hope this helps :D

Which is the equation of the line with slope 3 that contains point (-1, 5)?

sattari [20]

$\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{5})~\hspace{10em} slope = m\implies 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-5=3[x-(-1)] \\\\\\ y-5=3(x+1)\implies y-5=3x+3\implies y=3x+8$
