Answer:

The range of the given data set is 6.

Step-by-step explanation:

Range of the data set provides us with some basic information regarding spread of the data.

It is commonly used and quite easy to find.

First step is to arrange the values from the lowest to the highest.

It is already given arranged, so that will savd us some time.

Next step is simply subtracting the two values on the extremes, or, simply put, subtract the lowest from the highest value.

So, the range in this case would be 7-1=6.

F(x)=x^2+10x-12
weqwewe [10]

Answer:

Therefore the two values required are 2.08 and -11.08.

Step-by-step explanation:

i) f(x) = x^{2} +  10x - 12 is a quadratic equation and a quadratic equation will have two roots whose values when substituted in to the given quadratic equation will give the value.

ii) The question is therefore essentially asking us to find the roots of the given quadratic equation.

This can be done by equating the given quadratic equation to zero and then solving the equation for its roots.

∴ x^{2} + 10x -12 = 0    ⇒    x  = (-10 ± \sqrt{10^{2} +(48)} ) ÷ 2                                                          

                                          = (-10 ± 12.166)÷2        =   2.08, -11.08

Therefore the two values required are 2.08 and -11.08

Find the values of x and y
PSYCHO15rus [73]

Hi there!

So you're looking at an equilateral triangle, which is a big word that basically means all three sides are equal and all three angles are 60°.


Knowing that, the mesure of one side is 7, so necessarily the side "x" is also equal to 7.

So the value of x is : 7


And since all angles are of 60°, necessarily the angle "y" has an angle of 60°.

So the value of y° is : 60°


There you go! I really hope this helped, if there's anything just let me know! :)

Melanies blue notebook cover is 20 centimeters by 30 centimeters. She has a sticker for each letter in her name. Each sticker is
gizmo_the_mogwai [7]
Find the surface area of her notebook.

30 + 30 + 20 + 20 = 100

Now find the surface area of the square stickers.

2 + 2 + 2 + 2 = 8

So this is the surface area of one square, now multiply it by 8.

8 * 7 = 56

This is the surface area of all the stickers, now subtract it to the surface area of the notebook:

100 - 56 = 44

So 44 centimeters of the notebook cover will still be showing.

On Monday, Jullo ran 39 miles. On Tuesday, he ran another
Artist 52 [7]
<h3>Answer:</h3>

67 miles

<h3>Step-by-step explanation:</h3>

On Monday, Jullo ran <u>39 miles.</u>

  • ⇒ Monday = 39 miles

On Tuesday, he ran <u>24 miles.</u>

  • ⇒ Tuesday = 24 miles

On Wednesday, he ran <u>4 miles.</u>

  • ⇒ Wednesday = 4 miles

<u>Finding the total miles:</u>

Total miles ran on Monday, Tuesday, and Wednesday = 39 + 24 + 4

                                                                                            = 67 miles
