Find the probability. There are six nickels and seven dimes in your pocket. You randomly pick a coin out of your pocket and then

Anettt [7]

Answer:

$\frac{6}{13}\cdot \frac{6}{13}$

Step-by-step explanation:

We have been given that there are six nickels and seven dimes in your pocket. We are asked to find the probability of getting a nickel coin both times with replacement.

Let us find probability of getting a nickel in one pick.

$\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$

There are 6 nickels and total coins are 6 nickels plus 7 dimes that 13 coins.

$P(\text{Nickel})=\frac{6}{13}$

Since the coin is returned back in the pocket, so probability of choosing 2nd nickel will be $\frac{6}{13}$ .

Since both terms are independent, therefore, probability the required probability will be product of $\frac{6}{13}$ and $\frac{6}{13}$ .

$P(\text{Getting two nickels})=\frac{6}{13}\cdot \frac{6}{13}$

Therefore, our required probability would be $\frac{6}{13}\cdot \frac{6}{13}$ .

Answer: 1. -90

Step-by-step explanation:

5xy², if x=-2 and y=-3

You substitute the value into the original expression

5xy²

=5(-2)(-3)² ⇔ substitution

=(-10)(9) ⇔ multiply 5 and -2, and simplify (-3)²

=-90

The polynomial 3x 2 - 10x + 8 has a factor of 3 x -4 what is the other factor of 3 x 2 - 10x + 8

Dmitriy789 [7]

The other factor is

$3x^2 - 10x + 8 = 3x^2 -6x -4x + 8 \\
= 3x(x - 2) - 4(x - 2) \\
= (3x - 4)(x-2)$
