I learned this in class a couple weeks ago in intermediate algebra
Answer: b) The data is spread close to the mean
Step-by-step explanation: Theoretically, when the standard deviation of a statistical data is large or high, it simply means that the values in such statistical data set are farther away from the mean, On the other hand when the standard deviation is small or low, it simply means that the values of such statistical data are close to the mean of those data on average.
Therefore Judy's low standard deviation for her project simply indicates that her statistical data set is spread close to the mean.
The correct answer is C. A scalene triangle can be a right triangle.
This is because a scalene triangle is a triangle where all of the sides and angles are different from one another. This automatically tells us that options A and D are incorrect, because equiangular triangles have all 3 angles equivalent and if two sides were of equal length in the triangle, then it would not be scalene.
This leaves us with options B and C. An obtuse triangle simply has one angle with a measure greater than 90 degrees, and a right triangle is a triangle with a right angle (an angle that measures exactly 90 degrees). Scalene triangles can be both obtuse and right, as long as the side lengths and angles are not equal to one another. This makes option B incorrect, and option C the only correct option out of the four.
Your answer is option C.
Hope this helps!
Answer:
A = 907.46 
Step-by-step explanation:
C = πd
34π = πd
d = 34
r = 17
A = 
= 3.14(
) = 3.14(289) = 907.46
Step-by-step explanation:
y=x+1
y= -½x -8
x+1= -½x -8
1½x= -9
x = -9/ 1½
x = -6
y = -6+1 = -5
the solution (-6, -5)
