Answer: 2(2y+5)
Explanation:
One possible factorization is 2(2y+5)=4y+10, which would correspond to a set of dimensions 2 by (2y+5) for the rectangle.
Note that this is only one of many possibilities to come up with the dimensions. For example another possibility would be 1*(4y+10), or 4*(y+2.5). In fact, in Real numbers, there are infinitely many possible rectangles with a particular area.
Answer:
x = 85 deg
Step-by-step explanation:
We can see that there are two straight lines that intersect and that the two angles given are opposite angles.
Because they are opposite angles, the two angles have the same value, i.e
(x + 5) = 90 (subtract 5 from each side)
x = 90 - 5
x = 85 deg
Answer:
B. 78 and 82.
Step-by-step explanation:
We have been given that the average test score of the class was an 80 and the standard deviation was 2. We are asked to find two values between which 68% of class will score.
We know that in a normal distribution approximately 68% of the data falls within one standard deviation of the mean.
So 68% scores will lie within one standard deviation below and above mean that is:
Upon substituting our given values, we will get:
Therefore, about 68% of the class would score between 78 and 81 and option B is the correct choice.
