Answer:

Both the mean and the median


Step-by-step explanation:

Whichever measure, mean or median, is higher, Ari will benefit from that.


<u>Median:</u>

Median is the "middle value" of the list when arranged from least to greatest.

<em>Since there is 6 numbers, the middle number is between the 3rd and 4th number. Hence, we take the average of the 3rd and 4th number.</em>

Arranged from least to greatest: 73, 76, 80, 88, 90, 97

Average of 3rd and 4th is the Median = \frac{80+88}{2}=\frac{168}{2}=84


<u>Mean:</u>

Mean is the sum of all the number divided by the number of numbers (6).

So we have:

Mean = \frac{88+73+97+76+90+80}{6}=\frac{504}{6}=84

Mean is 84


Since Mean and Median are both same (84%), both will be best measure of center for Ari.

Find the value of x.
dimaraw [331]

Answer:

2\sqrt{77}

Step-by-step explanation:

Use the Pythagorean theorem. a^{2} +b^{2}=c^{2}

a and b are the two side lengths

c is the hypotenuse (value across from the right angle)

Plug in the values that you are given.

a^{2} +4^{2} =18^{2}

Solve for x

x^{2} =18^{2} -4^{2}

x^{2} =308

x=\sqrt{308}

x=2\sqrt{77}

Find the equation of the line, in slope intercept form that passes through the point (-6,5) and has slope 1/3
nexus9112 [7]

Answer:

y = x/3 + 7

Step-by-step explanation:

Use the equation: y - y1 = m(x - x1)

Plug in the given values into the equation:

y - 5 = (1/3)(x + 6)

Simplify the right side:

y - 5 = (x/3) + 2

Finally, add 5 to both sides:

y = x/3 + 7

Plz help me I don't know how to do this!!!!
m_a_m_a [10]

Answer:

x = 25

Step-by-step explanation:

Since it is an equilateral triangle it means that all the sides are 50. Each side is equal so, if you divide 150 by 3 you get 50. (and since perimeter is the adding of each side)

Now you want to try to figure out what the altitude is of the triangle so you divide it in half. Making the bottom side length now 25 because half of 50 is 25. You now have to use Pythagoreans theorem to figure out the altitude:

c^2 - a^2 = b^2

50^2 - 25^2 = b^2

2500 - 625 = b^2

1875 = b^2

√1875 = b

43.30127019

now you put that into the expression: x√3:

x√3 = 43.30127019

x = (43.30127019) ÷ (√3)

x = 25

Hope this helped!

The equation of the graphed line 2x + 3y = -6 written in standard form is,\rm y= -\frac{2}{3}x -2 and for line 2x + 3y = 6 will be,\rm y = \frac{-2}{3}x+2

<h3>What is the equation?</h3>

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

a) 2x + 3y = -6

The line in which the standard form is found as;

Ax + By + C = 0

The typical form of a slope intercept is

y = mx+c

where m denotes the slope and b the line's y-intercept.

3y= -6-2x\\\\ y=\frac{-6-2x}{3}\\\\ y= -\frac{2}{3}x -2

To obtain the slope standard form, we rewrite. The obtained equation is in the form of the slope-intercept.

b) 2x + 3y = 6

The line in which the standard form is found as;

Ax + By + C = 0

The typical form of a slope intercept is

y = mx+c

where m denotes the slope and b the line's y-intercept.

\rm 3y= 6-2x \\\\ y=  \frac{6-2x}{3} \\\\ y = \frac{-2}{3}x+2

Hence, The equation of the graphed line 2x + 3y = -6 written in standard form is,\rm y= -\frac{2}{3}x -2
