Answer is B
How I got is because I had to first figure out what 40 seconds worth of heartbeats are equal to. 80 - 48 is 32 divided by 2 is 16. Next, I added 48 and 16 which got me 64. All I had to do next was to add 80 and 16 because the rate of heartbeats per 10 seconds is 16. 80+16=96 and thats how I figured that the answer is B

Answer:
Graph these points listed below
Step-by-step explanation:
Graph the following points:
(6 am, 50)
(9 am, 59)
(1 pm, 63)
(6 pm, 63)
(8 pm, 59)
(12 am midnight, 58)
Well, a way to do this problem would be to find the set of numbers that all of rational square roots. A list of perfect squares would be 1^2=1, 2^2=4, 3^2=9, 4^2=16, 5^2=25, 6^2=36, 7^2=49, 8^2=64, 9^2=81, 10^2=100.
The mean increases. When Deleware (2,000: 2) is included the mean must be divided by 9 instead of 8.
