Which equation represents a like that passes through (4,1/3) and has a slope of 3/4?

1 answer:

7 0

The slope intercept form is y = mx + b
you need to find the equation that has a slope of 3/4 and passes through (4,1/3)

Plug in the given into the equation
y = 3/4x + b
to solve for the y-intercept, plug in the given coordinate that the line passes through

1/3 = 3/4(4) + b
1/3 = 3 + b
subtract 3 from both sides
-8/3 = b

now back to the slope intercept equation
y = mx + b
plug in the slope and y-intercept
y = 3/4x - 2 2/3
or
y = 3/4x - 8/3

Hope this helps :)

Find the height of the pyramid.

SOVA2 [1]

Answer:

Step-by-step explanation:

Let the height of pyramid be h

$v = \frac{1}{3} lwh$

v= 224

w= 8

l= 12

224=1/3(12)(8)(h)

224=32h

h=224/32

h=7

Answer:

Because of the presence of an outlier (30), an extremely higher value when compared to others. Outliers affects the value of mean, thereby mean should not be used for data with outliers.

Step-by-step explanation:

For the set of data above, it would be misleading to use the mean as the center of measure for the number of points that she scored in each game because of the presence of outliers, the presence of extremely lower or extremely higher value makes the use of mean as a measure of central tendency inaccurate because the mean take into consideration all the values in a data including the outliers for its calculation, and the mean would tend to shift towards the outliers thereby misinterpreting the data. The presence of outlier which is 30 in the data given would shift the mean to the right towards 30, thereby misleading to represent the measure of central tendency. 30 is an outlier because it is extremely higher than the rest of the data (10,8,9,8,30).

In the presence of outliers it's best to use median or mode as an acceptable measure of central tendency.
