craig forgor how subtraction works

mistake 1: instead of doing 3x - x, he did like multiplication and also forgor about the negative sign and somehow got 3.

mistake 2: instead of doing 5y - 4y, he did 5y + 4y

if he did it right, the answer would be 2x + y

How do you solve 2/5g=3/5 with a whole number??? I'm stuck

Blababa [14]

Answer:

g = 3/2

Step-by-step explanation:

Step 1: Multiply both sides by 5 (the whole number).

$\frac{2}{5}g * 5 = \frac{3}{5} * 5$
$2g = \frac{15}{5}$
$2g = 3$

Step 2: Divide both sides by 2.

$2g/2 = 3/2$
$g = 3/2$

Therefore, g = 3/2.

A bag contains tickets numbered 1 through 5. Use the probability distribution to determine the probability of drawing an odd num

Makovka662 [10]

Answer:

The probability of drawing an odd numbered ticket is 60%.

Step-by-step explanation:

Odd numbered tickets:

Probability of one is 1/5 plus half of 1/5.

$P(X = 1) = \frac{1}{5} + \frac{1}{10} = \frac{3}{10}$

Probability of 3 is half of 1/5.

$P(X = 3) = \frac{1}{10}$

Probability of 5 is 1/5. So

$P(X = 5) = \frac{1}{5}$

Probability of drawing an odd numbered ticket:

$p = P(X = 1) + P(X = 3) + P(X = 5) = \frac{3}{10} + \frac{1}{10} + \frac{1}{5} = \frac{4}{10} + \frac{2}{10} = \frac{6}{10} = 0.6$

0.6*100% = 60%

The probability of drawing an odd numbered ticket is 60%.
