Answer: I think it is b
Step-by-step explanation:
Answer:
=NORM.INV(0.17,98,15)
Step-by-step explanation:
Consider X represents the IQs of sample participants.
Then X follows the Normal Distribution with mean 98 and standard deviation 15.
That is,

The probability value is 17th percentile (that is 0.17)
To find the value of X using Excel, the<em> Inverse Normal Distribution </em>is used.
The Excel function =NORM.INV(0.22,105,17) is used to find the IQs of sample participants.
Answer: m=vD
Step-by-step explanation:
To get m alone, you want to use algebraic properties.
[multiply both sides by v]
Now that we have mass alone, we know that m=vD.
Answer. D) -1.9 and 2.6 are the solutions because when x=-1.9 and x=2.6 we have two points where the graph are cut. That is to say we have the same points in both graphs.
Answer:
P(A) = at most 25 of them like to swim
P(B) = at least 26 of them like to swim
P(A) +P(B) = 100%
=> P(B) = 100-P(A) = 100-38 =62%
=> B is correct
