25 tagged deers, 125 deers not tagged
total of 120 tagged deers
120/25 = 4.8
125 x 4.8 = 600
600 + 120 = 720
So there are a total of 720 deers in the refuge.
68% of the time, values will be within ONE std dev of the mean.
Thus, if the mean is 50 and the std. dev is 5, values will be between 45 and 55.
45 is one std dev below the mean, whereas 55 is one std dev above.
40 and 60 represent 2 std dev below the mean and above the mean, respectively. 95% of the time, values will be within the interval (40,60).
Here we're making use of the so called EMPIRICAL RULE.
99.9% of the time, values will lie within 3 std dev of the mean. This comes out to (45, 65). Unsure of how to conclude the 3rd question here.
Answer: 90 words per minute
====================================================
Work Shown:
270 words : 3 minutes
270/3 words : 3/3 minutes ..... divide both parts by 3
90 words : 1 minute
Brayden can type 90 words per minute (wpm).
Answer:
Every input can have only one output. But an output can have multiple inputs. Basically an x coordinate can have the same y coordinate as another ordered pair but not the same x coordinate. This is why d) does not represent a function.
Step-by-step explanation:
(4,-2)
(4,2)
4 is mentioned twice and every input( x value) can have only one output ( y-value)
