Answer:
Step-by-step explanation:
1. cannot be determined. We don't have all the numbers so you can't find the mean (average).
2. True. The median is the line in the middle of the box. The median for movie 1 is greater than 600 and the median for movie 2 is less than 600.
3. True. Interquartile range is the biggest number of the box minus the smallest number of the box. Movie 1 is approximately 200 and movie 2 is approximately 70.
4. True. Q3 is the last line of the box.
Since she answered 90% of her quiz correct, that means if she were to answer 10 questions, 9 would be correct. Lucky for us, 50 is a multiple of 10. If you multiply 10 by 5, you'd get 50. You would also need to multiply 9 by 5 as well. When you do this you'd get
45/50 correct. (divided them to make sure you get .90 if so, I'm right :)
Answer: To answer your question: If two of the angles of two triangles are the same, the triangles are similar. ... If two of the angles are known, the third can be found by subtracting the two known angles from 180. If the three angles of two triangles are the same, the triangles have the same shape and are similar.
Step-by-step explanation:: I have now explained to you why the Angle- Angle Triangle Similarity Theorem works i hope Iwas able to help good luck
Answer:
f(x) = 2(1/3)^x
Step-by-step explanation:
To find the parameters of this exponential equation, follow the instructions given in the hint.
__
b = 6/18 = 1/3 . . . . . divide 6 by 18 to find 'b'
18 = a(1/3)^-2 . . . . . substitute a point and 'b' in the equation
18(1/3)^2 = a = 2 . . . . multiply by (1/3)^2
The equation is ...
f(x) = ab^x
f(x) = 2(1/3)^x
C the third one because it’s proportional to the tshirts
