Answer:
49
Step-by-step explanation:
Let x be unknown number which should be added to numbers 1, 11, 23 to get geometric progression. Then numbers 1 + x, 11 + x, 23 + x are first three terms of geometric progression.
Hence,
and
Express q:

Answer:
a)
b)
c) Mary's score was 241.25.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
a) Find the z-score of John who scored 190
b) Find the z-score of Bill who scored 270
c) If Mary had a score of 1.25, what was Mary’s score?
Mary's score was 241.25.
Answer:
the actual answer is 0.56338028169 but you can reduce it to 0.563
Step-by-step explanation:
volume = l x w x h
51 x 44 x 8 = 17952 cubic feet
1 cubic foot = 0.0283168 cubic meters
17952 x 0.0283168 = 508.343 cubic meters
1 cubic meter = 1,000,000 cubic centimeters
508.343 x 1000000 = 508,343,000 cubic centimeters
The answer is A. -3 and its a negative result cause that's how it is, like for ex, -15/3 = -5 or 15/-3 = -5 is a negative, and w<span>hen two positive numbers are divided, the answer is a positive number 15/3 = 5.</span>
