Answer:
x = -21/11
Step-by-step explanation:
6(2x + 4)2 = (2x + 4) + 2
12(2x +4) = 2x + 4 + 2
24x + 48 = 2x +6
22x = -42
x = -21/11
the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.
x+(2x+15)+the measure of angle Q should equal 180.
Since everything is addition, the parenthesis can be removed.
x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.
Unfortunately I don't really know what to do from here, but I hope it helped at least a little.
The answer will be Mean = 135 Variance = 62 and Standard Deviation = 8
<h3>What is the standard deviation? </h3>
Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.
Given that :
Proportion (p) = 54%
Sample size (n) = 250
Using Normal approximation :
Mean = np
Mean = 250 * 0.54 = 135
Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46
Variance = (250 * 0.54 * 0.46) = 62.1 = 62
Standard deviation = √variance = √62.1
Standard deviation = 7.8803553 = 8

In a physics equation, given a constant acceleration (a, the change in
velocity of an object) and time involved (t), you can figure out the
distance (S) traveled by using this formula :
S = 1/2 x acceleration(a) x times(t)^2
So in this case, we can compute the distance by supplying the available data into the equation,...
S = 1/2 x 3.2 m/s2 x (32.8s)^2
S = 1721m
