The standard deviation, the range, and the interquartile range (IQR) summarize the variability of the data. a. Why is the sta

Elza [17]

Answer:

Step-by-step explanation:

a) The standard deviation is usually preferred over the range because it is calculated from all of the data and will not be impacted as much as the range when they are outliers,and the standard deviation uses all of the data.

b)The IQR sometimes referred to the standard deviation when there is an outlier because the IQR is less sensitive to this features than standard deviation.

that is the IQR is not affected by an outlier,while the standard deviation is affected by an outlier.

c)The advantage of the standard deviation over the IQR is the standard deviation takes into account the values of all observation,while the IQR uses only some of the data.

Express 16 1/4in simplest radical form

elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

${16}^{ \frac{1}{4} } \: can \: also \: be \: written \: as \: ( {{2}^{4})}^{ \frac{1}{4} }$

because ${2}^{4} = 16$

So,

${( {2}^{4} )}^{ \frac{1}{4} } = {(2)}^{4 \times \frac{1}{4} } = 2$

Jake opens a credit card with 18% annual interest compounded monthly. If he charges $800 on the card and never pays it off, how

Makovka662 [10]

<h3>Answer: $1,143.60</h3>

Work Shown:

A = P*(1+r/n)^(n*t)

A = 800*(1+0.18/12)^(12*2)

A = 1,143.60224954321

A = 1,143.60

Notes:

P = 800 is the principal. It is the amount loaned to Jake.
r = 0.18 is the decimal form of the 18% interest rate
n = 12 because we're compounding monthly, i.e. 12 times a year
t = 2 = number of years
For more information, check out the compound interest formula.

A landscaper, who just completed a rectangular flower garden measuring 15 feet in length by 7 feet in width, orders 1 cubic ya

grin007 [14]

The width of the border will be 0.1648... ft or 1.9786... inches.

<u><em>Explanation</em></u>

Lets assume, the width of the border is $x$ ft.

The rectangular garden is 15 ft in length and 7 ft in width. So, the area of the garden $=(15*7)ft^2= 105 ft^2$

Now, the length of the garden including border $=(15+2x) ft$ and the width of the garden including border $=(7+2x) ft$

So, the area of the garden including the border $= (15+2x)(7+2x) ft^2$

Thus the area of the border $=[(15+2x)(7+2x)-105] ft^2$

Total amount of premixed cement needed is 1 yard³ = 27 ft³

As the depth of the border is 44 inches or $(\frac{44}{12})ft$ or $(\frac{11}{3})ft$ , so....

$\frac{11}{3}[(15+2x)(7+2x)-105] = 27\\ \\ 11(105+44x+4x^2 -105)=81\\ \\ 11(4x^2+44x)=81\\ \\ 44x^2+484x-81=0$

Using quadratic formula....

$x= \frac{-484+/-\sqrt{484^2-4(44)(-81)}}{2(44)}\\ \\ x= \frac{-484+/-\sqrt{234256+14256}}{88}\\ \\ x= \frac{-484+/-\sqrt{248512} }{88}\\ \\ x= 0.1648...$

<u>(Negative value ignored)</u>

So, the width of the border $=0.1648...ft= (0.1648...*12)inches= 1.9786...inches$
