Please help!! Please give step by step so i can understand
miss Akunina [59]

Answer:

p = - 14

Step-by-step explanation:

Using the rules of exponents

a^{m} ÷ a^{n} = a^{(m-n)}

(a^{m}) ^{n} = a^{mn}

Note 81 = 9² and 729 = 9³

Given

(81)^{-4} ÷ (729)^{2-p}

= (9^{2}) ^{-4} ÷ (9^{3}) ^{2-p}

= 9^{-8} ÷ 9^{6-3p}

= 9^{-8-(6-3p)}

= 9^{-8-6+3p}

= 9^{3p-14}

Thus

9^{3p-14} = 9^{4p}

Since bases on both sides are equal then equate the exponents

4p = 3p - 14 ( subtract 3p from both sides )

p = - 14

a probability experiment consists of fair eight sided die find the probability of rolling number greater than 4 ​
Lunna [17]

Answer:

Probability[Number greater than 4] = 1/2

Step-by-step explanation:

Given:

Total side of die = 8

Find:

Probability[Number greater than 4]

Computation:

Number greater than 4;

[5,6,7,8]

Total number greater than 4 = 4

Probability[Number greater than 4] = Total number greater than 4 / Total side of die

Probability[Number greater than 4] = 4 / 8

Probability[Number greater than 4] = 1/2
