Answer:

B) median < mean

Step-by-step explanation:

To find the median, take away one of the frequencies until you have only one left. The median is 6.

To find the mean add up all of the numbers and divide by how many numbers are used. 3 + 4(3) + 6(8) + 8(3) + 10(2) + 11 = 118/17 = 6.94

This means that the mean is greater than the median.

Answer:

B) median < mean

To find the median, take away one of the frequencies until you have only one left. The median is 6.

Step-by-step explanation:

The corresponding 'x' value is an estimation of the median. If we divide a cumulative frequency curve into quarters, the value at the lower quarter is referred to as the lower quartile, the value at the middle gives the median and the value at the upper quarter is the upper quartile.

PLEASE HELP A QUESTION OF LIFE OR DEATH!!!!!!!
Ira Lisetskai [31]

Answer:  The length of the third straw is 29 centimeters.

Step-by-step explanation:  Given that Anja is creating a triangle using three straws and the lengths of two shorter straws are 20 cm and 21 cm.

We are to find the length of the third straw in centimeters so that Anja will create a right triangle.

The two shorter straws will make the legs of the right-angled triangle because they are shorter.

Since the third straw will be the largest, so it will make the HYPOTENUSE of the triangle.

In a right-angled triangle, we have

Hypotenuse² = length of one leg² + length of the other leg².

Therefore, we get

Hypotenuse^2=20^2+21^2=400+441=841\\\\\Rightarrow Hypotenuse=29.

Thus, the length of the third straw is 29 centimeters.

Complete the expression that represents the table<br><br> Y=___x
bezimeni [28]

Answer:

The equation that represents the table is:

  • y=\frac{9}{2}x

Step-by-step explanation:

Taking two points from the table

  • (2, 9)
  • (4, 18)

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(2,\:9\right),\:\left(x_2,\:y_2\right)=\left(4,\:18\right)

m=\frac{18-9}{4-2}

m=\frac{9}{2}

As the slope-intercept form is

\:y=mx+b

Plugging (2, 9) to find the y-intercept 'b'

9=\frac{9}{2}\left(2\right)+b

\mathrm{Switch\:sides}

\frac{9}{2}\left(2\right)+b=9

\mathrm{Remove\:parentheses}:\quad \left(a\right)=a

\frac{9}{2}\cdot \:2+b=9

9+b=9

b=0

so the equation becomes

\:y=mx+b

  • m=\frac{9}{2}
  • b=0

y=\frac{9}{2}\left(x\right)+0

y=\frac{9}{2}x

Therefore, the equation that represents the table is:

  • y=\frac{9}{2}x

The graph of the equation is also attached below.
