We meet again
so first divide 60 by 5
this gives 12
then multiply 12 by 4
giving a final answer of 48

Can two dot plots have the same median and range but have completely different shapes? Justify your answer using examples.

Verdich [7]

Yes because the median and range are not a function of the totality of the sample set, the median is just value that is halfway of the set. and the range are the difference of the highest and lowest value. as long as the lowest values, highest value and the halfway value are the same in each set the median and range will be equal no matter what are the other values of the set.

If a customer uses 80 MB, the monthly cost will be $19.00. If the customer uses MB, the monthly cost will be $. Find a linear eq

CaHeK987 [17]

Answer:

$c = 4.211\cdot n$

Step-by-step explanation:

The linear equation has the following form:

$c = \frac{\Delta C}{\Delta n} \cdot n$

Where:

$n$ - Number of MBs of the data plan.

$c$ - Monthly cost of the data plan.

The slope of the function is:

$\frac{\Delta C}{\Delta n} = \frac{c}{n}$

$\frac{\Delta C}{\Delta n} = \frac{80\,MB}{19\,USD}$

$\frac{\Delta C}{\Delta n} = 4.211\,\frac{MB}{USD}$

The equation is:

$c = 4.211\cdot n$

A 70-foot wire attached to the top of a building is anchored to the ground 20 feet from the base of the building. Which value is

JulijaS [17]

Answer:

The the angle which the wire make with the ground is 1.280 radian .

Step-by-step explanation:

Given as :

The length of the wire attached to the top of building = OB = 70 foot

The distance of wire anchored from base of ground = OA = 20 feet

Let the angle made by wire en and ground = Ф

Now from , In Triangle AOB

Cos angle = $\dfrac{\textrm Base}{\textrm Hypotenuse}$

Or, Cos Ф = $\dfrac{\textrm OA}{\textrm OB}$

or, Cos Ф = $\dfrac{\textrm 20}{\textrm 70}$

Or, Cos Ф = $\dfrac{\textrm 2}{\textrm 7}$

∴ Ф = $Cos^{-1}(\frac{2}{7})$

I.e Ф = 73.39°

Now in radian ,

∵ 180° = $\pi$ radian

∴ 73.39° = $\frac{\pi }{180}$ × 73.39°

= $\frac{3.14 }{180}$ × 73.39° = 1.280 radian

Hence The the angle which the wire make with the ground is 1.280 radian . Answer

Find side x, giving your answer to 1 decimal place.<br> 810<br> 7 cm<br> 40°<br> Х

Andru [333]

Answer:

10.8

Step-by-step explanation:

By sine rule:

$\frac{x}{ \sin 81 \degree} = \frac{7}{ \sin 40 \degree} \\ \\ x = \frac{7 \sin 81 \degree}{ \sin 40 \degree} \\ \\ x = \frac{7 \times0.9876883406 }{0.6427876097} \\ \\ x = \frac{6.91381838}{0.6427876097} \\ \\ x = 10.755992 \\ \\ x \approx 10.8$
