Answer:
B. 31.62
Step-by-step explanation:
First, find the distance of the line using the distance formula, 
. Plug the two points (-1,0) and (5,2) into the formula and solve. This gives you 6.32, then this is only one line of a pentagon, which has 5 sides, so you need to multiply. Since you are finding the perimeter, which is all of the sides added together, multiply the one side by 5. 6.32*5=31.62.
Answer:
0.003
Step-by-step explanation:
By formula we know that:
z (x) = (x - m) / [sd / sqrt (n)]
where x is the value we want to know (60,000), m is the mean (63500), sd is the standard deviation (6100) and n is the sample size (35).
Replacing we have:
z (60000) = (60000 - 63500) / [6100 / sqrt (35)]
z = -3.39
If we look in the normal distribution table (attached), we have that the probability is 0.0003.
Answer:
x=5
Step-by-step explanation:
the square root of 25 is 5 and 5*5=25 so the answer is 5
Answer:
Step-by-step explanation:
Prime numbers are number that can only be divided by itself and 1.
E.g 2,3,5,7,11,13,17,19,23,29 etc.
So, note that this sequence doesn't have a pattern, it is neither Geometry Progression nor Arithmetic Progression.
Now, let take look at the model given
If n is prime, then 2n-1 is prime
Let take 5 for
n=5 is a prime number
2n-1=2(5)-1=10-1=9
9 is not a prime number so the model doesn't work
A prime number doesn't have sequence so, it cannot be model with sequence.
I hope this help
