2. You have a painting that is 30 in. wide and 22.5 in. tall. You would like to reproduce it on a sheet of paper that measures 8

A. So, what I did was divided 30/8.5 and 22.5/11, and used the smaller of the two answers because that way they'd both fit, so I got 2.045. (I'm not 100% sure, but that's what i'd do)
b. Do something similar, and divide both sides, this time 30/11 and 22.5/8.5, so 2.647.

If f(x)=3/x+2- sqrt x-3 f(7)=?

Dovator [93]

To get the answer, you need to solve the equation for x = 7.

f(7) = 3/7 + 2 - sqrt(7) - 3.

= 3/7 - 1 - sqrt(7).

If you need to simplify it further:

= -4/7 - sqrt(7).

If you need it in decimal form: = -3.2171798824

Answer:

4a^2-6b^2+12

Step-by-step explanation:

(a^2 - 2b^2 + 3) - (4b^2 - 5) + (3a^2 + 4)

distribute the negative sign to each term in the 2nd expression

a^2-2b^2+3-4b^2+5+3a^2+4

combine like terms

4a^2-6b^2+12

A report includes a statement that the "average" test score of applicants to medical schools is 28.4. What is the role of the t

qaws [65]

Answer:

See explanation below.

Step-by-step explanation:

The average is measure of central tendency that is also called sample mean and is calculated from the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

This is an estimator of the population mean and is unbiased since the expected value for the estimator is the same parameter as we can see here:

$E(\bar X)=\frac{\sum_{i=1}^n E(X_i)}{n} =\frac{n\mu}{n}=\mu$

And is important because is the most common measure of central tendency reported on any study.

Is important to remember that this measure can be affected by outliers , for this case when we have outliers is better use the median as a measure of central tendency
