Answer:

a) s= 9.74

D. 9.74

b) Median= 74

B. 74

Step-by-step explanation:

Part a

We have the following dataset given:

69 74 75 62 70 93 64 69 61 88 67 77 87 90 66 91 77 63 82 82 71 74 76 65 83

We can begin calculating the sample mean with the following formula:

\bar X = \frac{\sum_{i=1}^n X_i}{n}

And replacing we got:

\bar X = 75.04

Now we can calculate the sample deviation with the following formula:

s =\sqrt{\frac{\sum_{i=1}^n (X_i-\bar X)^2}{n-1}}

And after replace we got:

s= 9.74

Part b

For this case we need to sort the value on increasing way:

[1] 61 62 63 64 65 66 67 69 69 70 71 74 74 75 76 77 77 82 82 83 87 88 90 91 93

And the median would be the value in the position 13 and we got:

Median= 74

Please explain! <br><br> 1/2x+1/8y=3<br><br> Solve in Slope Intercept form.
charle [14.2K]

Answer:

y = 4x + 24

Step-by-step explanation:

The slope is the number in front of the x-value.

Slope intercept form is in the form of

y = mx + b  (or as how I learned it)

m is the slope, and b is the y-intercept (the number that is left on the side.)

You can rearrange this by moving the x to the right side by subtracting it from both sides.

You now have 1/8y = 3 - 1/2x

which can be rearranged to

1/8y = -1/2x + 3.

You need to change the y to 1 whole instead of 1/8, so you multiply it by 8 since 8 divided by 8 is 1.

y = -4x + 24
