Answer:
No solution or x ∈ ∅
Step-by-step explanation:
We have given the equation ⇒ x+12 = (x+14) -3
if we solve this equation ⇒ x+12 = x+14-3
⇒x+12= x+11
⇒12 ≠ 11
which state that x ∈ ∅
i.e. there is no value of x which make the equation true
therefore, No solution
Answer:
2x5x5
Step-by-step explanation:
Exponential Form: 2^1 x 5^2
Answer:
The probability of a correct guess on the first try is 0.000244 or 0.0244%.
Step-by-step explanation:
Given:
Number of digits in the pin code = 6
Number of keys in each digit = 4
So, in order to get the correct pin code, the key selected in each digit should be correct.
So, there will be only 1 correct key in each digit.
Now, probability of selecting a correct key in first digit is given as:
Now, there are 6 digits in the pin code and repetition is allowed. So, the probability of selecting the correct key in the remaining digits will also be equal to 0.25.
Therefore, the combined probability of selecting the correct pin code in the first try is the product of probabilities of selecting each correct key in each of the digits.
So,
Therefore, the probability of a correct guess on the first try is 0.000244 or 0.0244%.
Quotient is basically the answer you get when you divide two numbers. For example, the quotient of 6 and 3 is 2 because when I divide 6 by 3, I get 2.
Quotient of a number x and 12 =
7 less than quotient of a number x and 12 =
5 times the number = 5*x = 5x
Hence, the equation is;
x =
= -1.423728813559322 ≈ 1.42
Hence, the answer is A.
