Answer:
12.
Step-by-step explanation:
We have been given format of different numbers. We are asked to find the missing value for our given format.
Taking square root of 9 and 16 we will get,
Similarly, we can see that by taking the square root of all the on the left side of equation and adding them we get right side of equation.
Upon taking square root of 25 and 49 we will get,
Therefore, the missing number of our given sequence is 12.
the answer would be C because none of the X values are the same
Answer:
x = √17
Step-by-step explanation:
x² = 4² + 1²
x² = 17
x = √17
Let's say the number is x.
The equation will be:
1/3x + 12 = x
(one third of a number + 12 equals to the number)
Solving the equation:
subtract 1/3x from both sides:
12 = 2/3x
divide by 2
6 = 1/3x
multiply with 3
18 = x
Your number is 18, its one-third is 6, which is 12 less than the number itself.
Answer:
2
Step-by-step explanation:
The z-score is the number of standard deviations the value is above the mean. If that number is 2, then Z=2. If that number is -2, then Z=-2.
___
Both Z=2 and Z=-2 are values that are two standard deviations from the mean.
