The heights in inches of males in the united states are believed to be approximately normally distributed with mean u the mean h
vovikov84 [41]

Answer:

Standard error = 0.83

Step-by-step explanation:

Given that the heights in inches of males in the united states are believed to be approximately normally distributed with mean u

Sample mean for 25 adults randomly taken =

\bar x = 69.72 inches

Std deviation of sample s = 4.15 inches

Since X  the height of males is Normal we find that the sample mean also will follow a normal distribution.

By central limit theorem, mean of x would be= sample mean= 69.72

Std error = \frac{s}{\sqrt{n} } =\frac{4.15}{5} \\=0.83

Standard error of the mean = std dev/square root of sample size.

Here only sample std deviation is known

So we used it

Standard error = 0.83

Given the expression 4x2y+5x−6xy2−4xy+6x2y, select the like term that would combine with 4x2y. −6xy2 −4xy 5x 6x2y
Gemiola [76]

The answer is: 6x^2y

I assume this is a question from k12 so I guarantee the answer above is

correct.

4x^2y and 6x^2y are like terms because they both have the same variables which is <u>x^2y</u>
