Answer:
- The limits are 908.6 cm^3 and 1417cm^3
- 1337.0cm^3 is in between the limits
Step-by-step explanation:
To determine the limit by taking into account the range rule of thumb, you use the fact that the limits are given by the mean plus and minus twice the standard deviation, that is:
(1)
: mean of brain volume = 1162.8 cm^3
σ: standard deviation = 127.1 cm^3
You replace the values of the parameters in the equation (1):

Limits = (1417 , 908.6)
The limits are 908.6 cm^3 and 1417cm^3
1337.0cm^3 is in between the limits calculated above.
Answer: 56%
Probably that it will rain and she goes + probably that it will be sunny and she goes
= 0.4 * 0.2 + 0.6*0.8
= 0.08 + 0.48
= 0.56
56% chance
Answer:
AB = 1.33
Step-by-step explanation:
AB and QR are in a ratio of 3 to 8 so we can create this proportion:
(3x+5)/24 = 3/8
cross-multiply:
8(3x+5) = 72
divide each side by 8 to get:
3x + 5 = 9
3x = 4
x = 4/3 or 1.33 repeating
