My son is trying to figure out how to decompose 8/12 and what he has to work with is x/2 + x/2 =8/12

1 answer:

4 0

X/2 + x/2 = 2x / 2 or just x. So x = 8/12 which can be simplified by their greatest common factor of 4. Divide both top and bottom by 4. This gives you x = 2/3.

Your answer for that equation is x = 2/3

Not sure what you mean by "decompose" though.

(question 31) if arc mBC =120 and arc mAD =50 whatis the measure of angle DYC

g100num [7]

<h3>Answer: D) 95</h3>

===============================================================

Explanation:

First, let's calculate angle BYC. This is the angle formed by the chords that subtend the arcs mentioned. This angle faces or is aimed toward the direction of the arcs. To find this angle, we'll average the arc measures like so:

angle BYC = (arcAD + arcBC)/2

angle BYC = (50+120)/2

angle BYC = 170/2

angle BYC = 85 degrees

Then we'll use the idea that angles BYC and DYC are supplementary (aka they form a straight 180 degree angle)

angleBYC + angleDYC = 180

angleDYC = 180 - angleBYC

angleDYC = 180 - 85

angleDYC = 95 degrees

which is why the answer is choice D.

Determine whether the following results appear to have statistical significance, and also determine whether the results have pr

MA_775_DIABLO [31]

Considering the p-value of the test, it is found that the result has neither statistical nor practical significance, as it does not give sufficient evidence that the IQ is increases by 10 to 20 points.

<h3>What is the relation between the p-value and the conclusion of the test hypothesis?</h3>

Depends on if the p-value is less or more than the significance level:

If it is more, the null hypothesis is not rejected.

If it is less, it is rejected.

In this problem, the p-value is of 0.28, which is greater than 0.05, hence there is not enough evidence that the IQ increase is as stated, meaning that the result has neither statistical nor practical significance.
