-375 + -175 = -550
The final depth is 550 ft below sea level, or -550.
a² + 2ab + b² = (a+b) * (a + b) <span>pattern condensed multiplication</span>
x² + 10x + 25
a² + 2ab + b²
(1x)² + 2*1x*5 + (5)² = (a+b)*(a+b)
a=x 2ab= 10x b=5 = (x+5)*(x+5)
Answer : (x+5)*(x+5)
Using the Central Limit Theorem, the standard error of the distribution of differences in sample means is of 1.97.
<h3>What is the standard error for each sample?</h3>
According to the Central Limit Theorem, it is given by the <u>standard deviation of the sample divided by the square root of the sample size</u>, hence:
<h3>What is the square root of the distribution of differences?</h3>
It is given by the <u>square root of the sum of the standard errors of each sample squared,</u> hence:
s = sqrt(1.1² + 1.63²) = 1.97.
