Answer:
Michael is 36 years old
Step-by-step explanation:
Let M represent Michael's age, and let B represent Brandon's age,
"Michael is 4 times as old as Brandon" becomes
M = 4B
"Michael is also 27 years older than Brandon" becomes
M = B + 27
Since the two equations are equal to M, they are equal to each other, so we have...
4B = B + 27 now solve for B...
3B = 27
B = 9
There fore
M = 9 + 27 = 36
Multiply 20 by 5 to get 100 so multiply the 3 by 5 also to get 15% of the days.

Step-by-step explanation:
1/3+1/5×1/9 = 1/3+1/45 = 9/45+1/45 = 10/45 = 2/9
Answer:
Option C is correct, The scatter plot shows a positive association because y increases as x increases.
Step-by-step explanation:
We are given a graph of scatter plot of points. We need to choose correct option using graph.
Option A: The point (18,2) is an outlier. This point is not shown on graph.
False.
Option B: The scatter plot show linear association. This is not linear association because points are not col-linear.
False
Option C: The scatter plot shows a positive association. This is positive association because y increases as x increases.
True
Option D: The scatter plot shows no association. This is false because it shows positive association.
False
Answer:
x = -1 or x = -10
Step-by-step explanation:
x^2 + 11x + 10 = 0
x^2 + 10x + x + 10 = 0
x(x + 10) + 1(x + 10) = 0
(x + 1) (x + 10) = 0
x + 1 = 0 or x + 10 = 0
x = -1 or x = -10
