d. This option is correct
Step-by-step explanation: Took the test on USATest Prep
After all 20 tosses of the coin, a tail was recorded 11 times. We can write this as 11/20.
To convert this into a decimal, we simply multiply the numerator and denominator by 5 so that the fraction is out of 100, giving us 55/100.
When we do the sum of 55 ÷ 100, we get the answer of 0.55.
I hope this helps!
Answer:
When we have a function f(x) = y.
The rate of change between a and b (where a < b) is:
R = (f(b) - f(a))/(b - a)
In this case:
b = 3
a = 1
f(3) = 127
f(1) = 95
R = (127 - 95)/(3 - 1) = 16
The rate of change in that interval is 16.
