(a) P( fifth one is bad) = P( first 4 are OK) * P(5th is bad)
= (0.98)^4 * 0.02 = 0.0184 or 1.84%
(b) this will be (0.98)^10 = 81.70%
The guy on top is correct
Answer:
See explanation
Step-by-step explanation:
Given the function 
1. To reflect the graph of the function f(x) over the y-axis, you should change the slope of the line in opposite. The slope of the function f(x) is 7, so the slope of the reflected function will be -7 and the expression of the reflected function will be

2. To translate the function g(x) 3 units left, add 3 units to x, thus the expression for the function will be

See attached diagram for details.
Answer:
425 = 8.5x + 55
Step-by-step explanation:
His goal is $425, so that's what we want to equal. He saves $8.50 per week, so that's our variable and coefficient - x represents the number of weeks. Finally, he already has $55, so you add it to whatever he earns per week.
Add y to both sides
60=48y+y
undistribute y
60=y(48+1)
60=y(49)
divide both sides by 49
60/49=y
