30. The average of a list of 4 numbers is 92.0. A new list

klasskru [66]

<u><em>Answer:</em></u>

H. 94.0

<u><em>Explanation:</em></u>

The original list: $a _1$ $a _2$ $a _3$ $40$

The new list: $a_1$ $a_2$ $a_3$ $48$

$\frac{a_1+a_2+a_3+40}{4} =92$

$a_1+a_2+a_3=92$ × $4-40=328$

$\frac{a_1+a_2+a_3+48}{4} =\frac{328+48}{4} =94$

Find the value of x? PLEASE HELP ME (:

vova2212 [387]

The shape in the middle is a quadrilateral, so the bottom right hand corner should add up to the rest of the angles to give 360 degrees.

40 + 80 + 110 = 230°

360 - 230 = 130°

The line on which x is on is a straight line, and a straight line is 180 degrees.

Therefore x has to be 180 - 130 to make sure it adds up to give 180 degrees.

180 - 130 = 50

∴ x = 50°

Rate of change of [1,3] is $\frac{15.882-11.38}{3-1} = \frac{4.502}{2} =22.51$
Rate of change of [-4, -2] is $\frac{.0971-.0018}{-3--4} = \frac{.0953}{1}=.0953$
The difference between them is 22.51-.0953=22.4147

Hope that helps
