Which excel cell entry will calculate the square root of 165? =sqrt[165] sqrt(165) sqr(165) =sqrt(165)?

svetoff [14.1K]

Excel expects a + or = sign before math calculations.
Also, for arguments of functions (such as sqrt), parentheses "()" are used. Brackets "[]" are not acceptable.
That leaves only one remaining option.

Leya [2.2K]

In total, Kay took 5+14+2=21exams. she got 80%-90% on 14 of them. the probably is 14/21 which is 2/3. Therefore, the probability of Kay getting 80%-90% on her next exam is 2/3 or 66.6%

Answer:

Gerrard

Step-by-step explanation:

Let the size of each poster be $x$

Eve's poster portion painted will be

$=\frac{1}{6}\times x\\=\frac{x}6}$

Gerrard's painted portion will be:

$=\frac{1}{5}\times x\\=\frac{x}{5}$

From the two inequalities, we find that $\frac{x}{5}$ is greater than $\frac{x}{6}$ by x/30

$\frac{x}{5}-\frac{x}{6}\\=\frac{x}{30}\\$

hence Gerrard has the larger blue section. His portion is 16.67% greater than Eve's

Lynn asked six friends how many cars their parents own. She recorded 1, 1, 2, 2, 2, and 4 cars. What is the mean absolute deviat

Daniel [21]

If number of cars recorded by Lynn is 1, 1, 2, 2, 2, and 4 cars then the mean absolute deviation of the number of cars is 0.7

<h3>What is the mean absolute deviation?</h3>

The mean absolute deviation of a data set is the average of the absolute deviations from a central point .

Data we have is

1,1,2,2,2,4

Mean can be calculated as

$&\text { Mean }=\frac{1+1+2+2+2+4}{6}\\ \\&\text { Mean }=\frac{12}{6} \\\\&\text { Mean }=2$

Absolute value between the data points and mean can be calculated as :

$\begin{aligned}&|1-2|=1 \\&|1-2|=1 \\&|2-2|=0 \\&|2-2|=0 \\&|2-2|=0 \\&|4-2|=2\end{aligned}$

Now mean absolute deviation can be calculated as :

$\begin{aligned}&\frac{1+1+0+0+0+2}{6} \\\\&=\frac{4}{6} \\\\&=0.66\end{aligned}$$$

Rounding to nearest ten

mean absolute deviation=0.7

If number of cars recorded by Lynn is 1, 1, 2, 2, 2, and 4 cars then the mean absolute deviation of the number of cars is 0.7
