Suki’s method is the best to use here. Dinah could only know students who read novels, making her sampling method more biased.

Suki’s method is definitely the better choice. It was randomly selected and includes a greater amount of students. Dinah’s method has a little more bias. It’s about the people SHE personally knows, and because of the variables in the survey (same class as Dinah? Is she in a higher education class? Part of a group?) So the answer is Suki. Once again, greater amount of participants, randomly chosen without any bias

51. Find the length of the unknown side x of this triangle, evaluate your answer to two decimal places.

Answers

Answer:

See work, below.

Step-by-step explanation:

The radius of this circle is 10 and so the diameter is 20. The measure of the angle opposite side x is found as follows:

adj side

cos theta = ------------------- = 18/20. Find theta:

hypotenuse

theta = arccos 18/20 = 0.451 radian.

Now use the sine function to find x:

x x

sin 0.451 radian = ------------------- = ------------- = 0.651

hypotenuse 20

which results in x = 20(0.651) = 13.02

x = 13.02 units

I should have used the Pythagorean Theorem up front.

18² + x² = 20² becomes x² = 400 - 324 = 76, and so x = √76 ≠ 8.72

Benjamin believes that 1/2 % is equivalent to 50%. Is he correct? Why or why not? Please explain.

Answers

Answer:

Benjamin is correct.

Step-by-step explanation:

1/2 converted to a decimal (1 divided by 2) is 0.50, which when converted to a percentage is 50%.

1 ÷ 2 = 0.5

.5 × 100 = 50 ⇒ 50%

So, 1/2% = 50%

Also, 1/2 is 50%. So, that should automatically prove that he is correct.

Hope this helps! :)

Tell whether the angles are complementary or supplementary. Then find the value of x.

this just confused me a bit. x - 20? They are complimentary so ik the other side has to be 20

Answers

As you should already know that the angle shown is 90°.

So,

x + (x - 20) = 90

Now we have to solve for x. To find x we need to isolate it (get it by itself)

Add 20 on both sides:

x + x = 110

Simplify:

2x = 110

Now divide 2 on both sides (to get x by itself)

x = 55

Let’s check our answer:

55 + ( 55 - 20) = 90

55 + 35 = 90

90 = 90

So your answer should be x = 55.
