Hat is he probability of pick 1 green marble from a bag with 7 green and 8 blue marbles

disa [49]

Answer:

7/15

Step-by-step explanation:

No. of green marbles in the bag= 7

No. of blue marbles in the bag= 8

Total no. of marbles in the bag= 7+8=15

As we know that,

Probability( of a random event A)= $\frac{Favourable\ no.\ of\ elementary\ events}{Total\ no.\ of\ elementary\ events}$

Hence in this case,

Favourable np. of elementary events (green marbles)=7

Total no. of elementary events (Total no. of marbles in the bag)= 15

Hence, Probability of picking a green marble from the bag= $\frac{7}{15}$

Answer:

$\bold{x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\quad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7}$

Step-by-step explanation:

$-2x^2-3x+4=0\\\\a=-2\,,\ b=-3\,,\ c=4\\\\\\x=\dfrac{-b-\sqrt{b^2\pm4ac}}{2a}=\dfrac{-(-3)\pm\sqrt{(-3)^2-4(-2)(4)}}{2(-1)}=\dfrac{3\pm\sqrt{9+32}}{-2}\\\\\\x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\qquad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7$

Alik [6]

You use the formula Interest=principle (rate) time or i=prt. If you use that formula to solve, your answer will be 3,500. After five years, the balance will be $3,500.
