Answer: 0.8
Step-by-step explanation:
Let's assume that 5 puzzles were solved in 5mins. That is, 1min for each puzzle to be solved.
From our assumption, our sample size will be 5.
The probability that a subject will solve more than 1 puzzle will be number of occurrence from 2 to 5 which is 4.
This gives: 4/5 = 0.8 to one decimal place.

Step-by-step explanation:
Answer:
4/5x + 7
Step-by-step explanation:
the slope-intercept form is y = ax+b
a is the slope, to figure it out the line is perpendicular to y = -5/4x+11/4
There is a rule said if two lines are perpendiculars, the multiplication of their slopes = -1, so -5/4 * a = 1, solve for a = 4/5
b is the intercept to get it use the point (0,7)
so y = 4/5x+b, 7 = 4/5 * 0 + b, then b = 7
What does the rest of the question say??
If AM=10, then AC=10 because both are radii. TC is a diameter so that’ll just be the radius doubled. TC=20!
