At first, let us solve The equation
We will subtract 4 from both sides
Then let us square both sides
Subtract 2 from both sides to get the value of x
You have two choices with 14
Which one will you choose?
To answer this you must know does this value including the domain or not
Let us try this value for x in the equation if the left-hand side equals the right-hand-side then the value is not extraneous
Since the right-hand side has the same value, so 14 is not extraneous.
So the correct answer is the third choice.
Answer:
Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself.
Answer:
0.15%
Step-by-step explanation:
The mean is μ = 3500 and the standard deviation is σ = 500.
2500 is 2 standard deviations below the mean, which we can calculate by finding the z-score.
z = (x − μ) / σ
z = (2500 − 3500) / 500
z = -2
According to the empirical rule, 99.7% of a normal distribution is between -2 and +2 standard deviations. Which means 0.3% is outside of that. Since a normal distribution is symmetrical, half of that, or 0.15%, is less than 2 standard deviations.
Answer:
1-120 in. 2-16cm 3-27 m
Step-by-step explanation:
Please be mad if im wrong
M=112
If 80 is m-32 than 80+32=112
