Answer:

1/21

Step-by-step explanation:

Cards: 2,3,4,5,6,7,8 7 cards

1st card :5

P(5) = number of 5's / total

= 1/7

Then we keep the card

Cards: 2,3,4,6,7,8 only 6 cards left

card less than 4: 2,3

P (card less than 4) = number of cards less than 4/ total cards

= 2/6 = 1/3

P (5, no replacement, card less than 4) = P(5) * P( less than 4)

= 1/7 * 1/3

=1/21

Help please!! i don’t understand this one!

12345 [234]

Answer:

C, D

Step-by-step explanation:

This equation can be solved any of several ways. One that doesn't require much thought is using the quadratic formula.

For ax² +bx +c = 0, the solutions are ...

$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

In the given equation, a=2, b=11, c=5, so this becomes ...

$x=\dfrac{-11\pm\sqrt{11^2-4\cdot2\cdot5}}{2\cdot2}=\dfrac{-11\pm\sqrt{81}}{4}\\\\x=\dfrac{-11\pm9}{4}=\left\{-\dfrac{20}{4},-\dfrac{2}{4}\right\}=\{-5,-\frac{1}{2}\}$

The solutions are ...

C. x = -5

D. x = -1/2

_____

My personal favorite is using a graphing calculator. The solutions are the x-intercepts of the expression on the left. That is, where its value is zero, as the equation says.
