2 − 10n = 2 + 4n<br> What does n equal?

tiny-mole [99]

Answer:

0 =n

Step-by-step explanation:

2 − 10n = 2 + 4n

Add 10n to each side

2 − 10n+10n = 2 + 4n+ 10n

2 = 2 + 16n

Subtract 2 from each side

2-2 = 2+16n-2

0 = 16n

Divide each side by 16

0/16 = 16n/16

0 =n

blsea [12.9K]

Answer: The probability that the fruit is an orange or a pear is $\dfrac{1}{3}$ .

Step-by-step explanation:

Given : Emily has 12 fruits in her bowl.

She has 3 apples, 5 bananas, 1 pear and 3 oranges.

A fruit is selected at random.

P(orange) = $\dfrac{\text{Number of oranges}}{\text{Total fruits}}$

$=\dfrac{3}{12}$

P(pear)= $\dfrac{\text{Number of pears}}{\text{Total fruits}}$

$=\dfrac{1}{12}$

Since both events of selecting orange and pear are mutually exclusive , so

The probability that the fruit is an orange or a pear = P(orange) + P(pear)

$=\dfrac{3}{12}+\dfrac{1}{12}=\dfrac{4}{12}=\dfrac{1}{3}$

Therefore , the probability that the fruit is an orange or a pear is $\dfrac{1}{3}$ .
