This is false. If you rotate a figure 180 degrees, then the figure will not have the same orientation, it will be upside down and in another quadrant.
Answer:
(A) The number of bacteria is originally 300 and increases by 30% every hour
Step-by-step explanation:
I am assuming the function should actually read:

(i.e., there should be a "t" in the exponent. if this is not the case please disregard my answer).
According to the above exponential function, the initial amount 300 grows as (1+0.3)*300=300+0.3*300. In other words it increases by 30% every hour (t).
Your answer choice (A) is likely a candidate, except I am missing "every hour" at the end (again, am assuming this was omitted by mistake)

Answer:
The formula to calculate standard deviation from probability is \sqrt(n*p*(1-p)). n is the sample size, and 200 in this case (number of putts for practice). p is 80% or 0.8, the probability that he can make it. So the standard deviation is \sqrt(200*0.8*(1-0.8)=\sqrt(200*0.8*0.2)=\sqrt(16)=4.
