Answers

Answer 1

Answer:

Answer:

The common incorrect answer given by students when solving the problem 8 -:- 1/2 is option b. 4.

Step-by-step explanation:

Answer 2

Answer:

Final answer:

The common incorrect answer given by students is 16 when solving the problem 8 -:- 1/2. Therefore, the correct option is A

Explanation:

The common incorrect answer given by students when solving the problem 8 -:- 1/2 is a. 16.

To solve this problem, we need to remember the rules of division. When dividing by a fraction, we actually multiply by its reciprocal. So 8 -:- 1/2 is the same as 8 x 2/1, which equals 16.

Therefore, the correct answer is a. 16.

16 to the power of 1 over 4 equals 8 to the power of 2 to the power of 1 over 4 equals 2 to the power of 2 multiplied by 1 over 4 equals 8

Answers

Answer:

Option A is correct.

Value of 16 to the power of 1 over 4 equals to the power of 4 to the power of 1 over 4 equals 2 to the power of 4 multiplies by 1 over 4 equal 2.

Step-by-step explanation:

To find the value of: 16 to the power of 1 over 4.

$16^{(1)/(4)}$

we can write 16 as:

$16 = 2 \cdot 2 \cdot 2 \cdot 2 = 2^4$

⇒ $(2^4)^{(1)/(4)}$

⇒ $(2)^{4 \cdot (1)/(4)}$ [∴ $(a^n)^m = a^(nm)$ ]

⇒2

Hence, the value of $16^{(1)/(4)}$ is, 2.

Therefore, the value of 16 to the power of 1 over 4 equals to the power of 4 to the power of 1 over 4 equals 2 to the power of 4 multiplies by 1 over 4 equal 2.

Ans. 16 to the power of 1 over 4 equals 4 to the power of 4 to the power of 1 over 4 equals 4 to the power of 4 multiplied by 1 over 4 equals 4

A bicycle lock requires a two-digit code of numbers 1 through 9, and any digit may be used only once. Which expression would determine the probability that both digits are even?

Answers

The expression which would determine the probability that both digits are even which is required for bicycle lock is (4P1)(3P1)/(9P2).

What do you understand by the term permutation?

The permutation is the arrangement of the things or object in a systematic order, in all the possible ways. The order of arrangement in permutation is in linear.

A bicycle lock requires a two-digit code of numbers 1 through 9, and any digit may be used only once. The probability of choosing 2 digits from 9 is,

$^9P_2$

There are total 4 even numbers {2,4,6,8}. The probability of choosing first digit's even from 4 even numbers is,

$^4P_1$

For the second digit to be even is,

$^3P_1$

Thus, the favorable outcome is, $(^4P_1)(^3P_1)$ and total outcome is $^9P_2$ . Thus, the expression which would determine the probability that both digits are even is,

$P=((^4P_1)(^3P_1))/(^9P_2)$

Thus, the expression which would determine the probability that both digits are even which is required for bicycle lock is (4P1)(3P1)/(9P2).

The correct answer is:

A. P(both even) = $((_(4)P_(1))(_(3)P_(1)))/(_(9)P_(2))$

The expression would determine the probability that both digits are even.
