Lets see, If "n" represents the number, then "the successor of a certain number" is n+1. Now if "Twice the number" is 2n now for the expression "The successor of a certain number when added to twice the number" would then be 2n+n+1, which the problem stated is equal to 61 Therefore we can say that the correct option would be 2n+n+1=61
Answer:
4(9)+8=44
Step-by-step explanation:
A.
Since about 95% of a normal distribution falls within two standard deviations of the mean, that leaves 5% that lie without, with 2.5% lying to either side.
b.
About 68% of a normal distribution lies within one standard deviation of the mean, so this probability is about 0.68.
c. You're looking for
such that
Since
occurs for
, it follows that
So there's a probability of 0.10 for having a demand exceeding about 1328 pounds.
Answer:
The terms of the polynomial are relatively prime because the highest integer that divides them both is 1.
Step-by-step explanation:
Two numbers are said to be relatively prime if their greatest common factor ( GCF ) is 1 .
Now, the expression we are given in the question is a polynomial;
y² + 7.
The terms of the polynomial y² + 7 are y² and 7 and have no common factor and in fact cannot be factorized further. Thus, these terms are said to be relatively prime because the highest integer that divides them both is 1.
