Answer:
Range: (844.9,1333.7)
A brain volume of 1348.3 cm cubed can be considered significantly high.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 1083.9 cm cubed
Standard Deviation, σ = 122.2 cm cubed
Range rule thumb:
- This rule state that the the range of data is four times the standard deviation of the data.
Upper Limit:
Lower limit:
Since, 1348.3 does not lie in the range (844.9,1333.7), a brain volume of 1348.3 cm cubed can be considered significantly high.
Step-by-step explanation:
1 cubic decimetre = 1000000 milimetres
Answer:
29°
Step-by-step explanation:
151° + a=180°
We know the sum of angles in a straight line is 180°
a= 180°-151°
The sign changed as it changed sides
a= 29°
Joe runs one lap around a track in 80 seconds. Joe and Jim meet after 30 seconds.We know how long does it take for Joe to run one lap, so we can calculate what distance he runs in 30 seconds:
He runs half lap for 40 seconds. He runs quarter lap for 20 minutes and he runs 1/8 lap for ten minutes. So for 30 seconds he runs 3 * 1/8 lap=3/8 lap.
Because Jim runs in opposite direction this means that he will meat with Joe at 1-3/8=5/8 lap. So, Jim runs 5/8 lap for 30 seconds.
1/8 lap Jim runs for 30/5=6 seconds, so Jim needs 8*6=48 seconds to run the lap.
After 30 seconds Joe has run e runs
To solve this problem you must apply the proccedure shown below:
1. You have the following points given in the problem above:
2. To find the midpoint, you must apply the formula that is used for calculate it. This is:
Where:
3. Now, you must substitute these values into the formula for calculate the midpoint, as following:
Therefore, the answer is:
