Johanna is trying to find the probability that a cup will land open end up. she takes the cupand tosses it in the air 100 times and each time records if it lands open end up or open end down. she finds that 63 times the cup lands open end up. what is the probability that the cup will land open end down

37/100 or 0.37.

Step-by-step explanation:

The cup lands open end up 63 times out of 100.  This means that

100-63 = 37 times out of 100, the cup lands open end down; this is

37/100, or 0.37.

step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
