Answer:

40° and 140° (with x = -10)

Step-by-step explanation:

Since the angles are supplementary (when added, equal 180°), you can add the two angles together to get (-18x)°. 180/-18 = -10 for x. Fill in -10 for x in both expressions. (-14 • -10)= 140° and (-4 • -10)- 40°. 140+40=180

The parameter of interest in this scenario is the proportion of all 1,000 students within the school who have "strict" parents or guardians.

<h3>How to calculate a test statistic?</h3>

In Mathematics, the test statistics of a given sample is calculated by using this formula:

$Z=\frac{x\;-\;u}{\frac{\sigma}{\sqrt{n} } }$

<u>Where:</u>

x is the sample mean.

u is the mean.

is the standard deviation.

n is the sample size.

In conclusion, a possible test statistic which can be used to estimate this parameter is the proportion of all students who have "strict" parents or guardians, based on the collected sample.

If 72 = 12x, what does x equal?

CaHeK987 [17]

Answer:

x=6

Step-by-step explanation:

So, x is our unknown variable. An so you have to ask yourself, what times 12= 72? The answer would be 6, because 12x6=72

The proper way to do it, would be to divide 12/12 so you isolate the variable, and what you do to one side, you do to the other, so divide 72 by 12 and you get 6! Hope this helps!
