A newspaper collected information on schools in its circulation area in order to compare their quality. Two measures the newspaper collected for each school, mean class size and mean score on a statewide reading exam, are shown in the scatterplot. One school in the report, Springside Elementary, is labeled in the graph.
Which is a true statement regarding Springside?
Springside does not affect the correlation.
Springside weakens the correlation shown in the scatterplot.
Springside strengthens the correlation shown in the scatterplot.
Removing Springside would increase the value of the correlation coefficient.
Answers
Interpreting the scatterplot, it is found that the correct option is:
Springside weakens the correlation shown in the scatterplot.
In the scatterplot, the mean test score is plotted as function of the mean class-size.From this, we can verify that as the mean class size increases, the mean score decreases, that is, there is a negative correlation between the mean class size and the mean test score.However, for Springside, the mean test score is greater than most other schools with smaller class sizes, which is a different result than expected, thus, it weakens the correlation, and the correct option is:Springside weakens the correlation shown in the scatterplot.

You measure an obtuse angle on a protractor. If neither of the rays of the angle points at 0° or 180°, where could they point? Give the two points using degrees and explain why you chose those points.
Answers
Answer:
Any point greater Than 0 and less than 180°
Step-by-step explanation:
Obtuse angle measures are angles which measures angles in the range between 0° and 180°. Angles which lies between these range are called obtuse angles. Hence, from the question, if the ray of points measured does not point to 0° or 180°; then, the ray of angle points could have pointed to any angle between greater Than Zero less than 180.
Hence the points could 10 and 120 or any other values which meets the obtuse angle condition.
Answer:
173-degree angle (any angle larger than 90 degrees is obtuse and why are there favorite numbers all of a sudden????)
145-degree angle (there really is no reason to choose 2 certain numbers)
Step-by-step explanation:

A manager at a factory finds that in a random sample of 250 watches, 3 are defective. Of the 7,500 watches from which the sample was chosen, about how many watches are not defective?
Answers
Answer: 7410 watches
Step-by-step explanation:
From the random sample of 250 watches, 3 are defective. The percentage that's defective will be:
= 3/250 × 100
= 1.2%
Percentage that's not defective = 100 - 1.2 = 98.8%
Therefore, from the sample of 7500 watches, the number that's not defective will be:
= 98.8% of 7500
= 98.8/100 × 7500
= 7410
Therefore, 7410 watches aren't defective

Answer is below. Look at the steps to understand the answer.
Step 1.We'll need to combine like-factors for (3⁻⁴ × 3⁻⁶)⁴.
To do that, we'll combine the exponents and copy the base number.
In the term, the like terms are...
3⁻⁴ and 3⁻⁶.
Like I said, when we need to combine the like-factors, we'll combine the numbers. Combine the numbers like this:
(3⁻⁴⁽⁻⁶⁾)⁴
Step 1a.Add the exponents.
Remember the integer rule.
P + P = P
N + N = N
P + N = P
P + N = N
According to the rule, a negative + negative = negative. So...
-4 + (-6) = (-10)
Step 2.We now need to make the exponent (3⁻¹⁰) positive.
Rule: A⁻ᴮ = ¹⁄ₐᴮ
According to the formula, A is the base number and B is the negative exponent.
That being said...
A → 3
B → 10
Now, since we know what A and B is, let's change our equation.
⅓¹⁰
Step 3Bring down the exponent 4 then multiply.
10 · 4 = 40
Therefore, the answer is ⅓⁴⁰.

What is Geometric sequence?An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.
Given that;
Consider the first four terms of the sequence are,
⇒ -3, -12, -48, -192, . . .
Here, Common ratio is,
⇒ - 12 / - 3
⇒ 4
Thus, The sequence are in Geometric sequence.
Hence, The value of 8th term of this sequence is,
⇒ a (8) = - 3 × (4)⁸⁻¹
⇒ a (8) = - 3 × 4⁷
⇒ a (8) = - 3 × 16,384
⇒ a (8) = - 49,152

5/8 divided by 9

Answers
Answer:
5/72
Step-by-step explanation:
dividing is equivalent to multiplying by the reciprocal
5/8×1/9
multiply the fraction
8×9=72
5×1=5
Answer: 5/72
Answer:
5/8 / 9 = 5/72
Step-by-step explanation:
5/8 / 9 = 5/72
Anytime you divide with a fraction remember this:
Same, change, flip:
You keep the first fraction, which is 5/8, the same.
Then you change the division sign to a multiplication sign.
After that, you flip the 9/1 (which is the same thing as 9) to 1/9.
So it would be 5/8 x 1/9.
If you multiply that, you can 5/72.
Therefore, 5/72 is your answer.
I hope this helped.
