Answer: your answer is 60
Step-by-step explanation: the explanation for this question is that all you got to do is add 36 plus 24 and you get 60 as your total
Check out the attached image below. I've marked two red points on the line such that the points have whole number coordinates. This way I could compute the slope of this line to be -2/5
We move down 2 units (rise of -2) as shown by the blue arrows. Afterward, we move 5 units to the right as shown by the green arrows (which is the run). This gets us from the left red point to the right red point.
rise = -2, run = 5
slope = rise/run = -2/5
the original line shown has a slope of -2/5
----------------------------
Next we do two things to get the perpendicular slope.
Flip the fraction: -2/5 becomes -5/2
Flip the sign: -5/2 becomes +5/2 or simply 5/2
----------------------------
Final Answer: 5/2
As you can probably tell, this is a 30, 60, 90 triangle. That means the degree measures are 30, 60, and 90. These are special triangles. For every 30, 60, 90 triangle in the world, the shorter leg (in your case, x) is ALWAYS two times shorter than the hypotenuse (6). 6/2=3, so x=3. Also, the longer leg for a 30, 60, 90 triangle is always equal to the shorter leg times the square root of 3. So, 3 times the square root of 3 is about 5.2. So, y=5.2. Hope it helps!
Answer:
The value of the test statistic is 6.642.
Step-by-step explanation:
A Chi-square test for Goodness of fit will be used to determine whether the viewing audience proportions changed.
The hypothesis is defined as:
<em>H₀</em>: The viewing audience proportions has not changed.
<em>Hₐ</em>: The viewing audience proportions has changed.
The test statistic is:
Here,
O = observed frequencies (O - E)²
E = expected frequencies = n × p
The table below shows the observed and expected frequencies.
Compute the test statistic value as follows:
Thus, the value of the test statistic is 6.642.
Answer:
Rearrange the numbers to their like terms.
which is 2x-x=56-20.
x=36.
