Simplify the expression (4x^3y^-5)^4

Elanso [62]

Answer:

64x^12 / y^20

Step-by-step explanation:

(4x^3y^-5)^4

Distribute the exponential value of 4 to all terms in the parentheses.

4^4 * x^(3*4) * y^(-5*4)

Multiply each exponent.

64x^12 * y^-20

Make the negative exponent positive by making it a fraction.

64x^12 / y^20

exam p A drawer contains four pairs of socks, with each pair a different color. One sock at a time is randomly drawn from the dr

Marta_Voda [28]

Answer:

The probability that the maximum number of draws is required is 0.2286

Step-by-step explanation:

The probability that the maximum number of draws happens when you pick different colors in the first four pick.

Assume you picked one sock in the first draw. Its probability is 1, since you can draw any sock.

In the second draw, 7 socks left and you can draw all but the one which is the pair of the first draw. Then the probability is $\frac{6}{7}$

In the third draw, 6 socks left and you can draw one of the two pair colors which are not drawn yet. Its probability is $\frac{4}{6}$

In the forth draw, 5 socks left and only one pair color, which is not drawn. The probability of drawing one of this pair is $\frac{2}{5}$

In the fifth draw, whatever you draw, you would have one matching pair.

The probability combined is 1× $\frac{6}{7}$ × $\frac{4}{6}$ × $\frac{2}{5}$ ≈ 0.2286

Taylor is 15 years younger than Marty. Twice Marty’s age added to three times Taylors age totals 205. What are the ages of Taylo

Inessa05 [86]

Answer:

Taylor's age = x = 35 years

Marty's age = y = 50 years

Step-by-step explanation:

Let

Taylor's age = x

Marty's age = y

Taylor is 15 years younger than Marty.

x = y - 15

Twice Marty’s age added to three times Taylors age totals 205.

205 = 2y + 3x...... Equation 1

Therefore, we substitute y - 15 for x in

205 = 2y + 3x...... Equation 1

205 = 2y + 3(y - 15)

205 = 2y + 3y - 45

Collect like terms

205 + 45 = 5y

250 = 5y

y = 250/5

y = 50 years

x = y - 15

x = 50 - 15

x = 35 years

Solving for x

Therefore:

Taylor's age = x = 35 years

Marty's age = y = 50 years
