Answer:
15.75
Step-by-step explanation:
A = (B + b)×h/2
= (4 + 5)×3.5/2
= 9×3.5/2
= 4.5×3.5
= 15.75
Answer:
3.84% of months would have a maximum temperature of 34 degrees or higher
Step-by-step explanation:
Problems of normally distributed samples are 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:
What percentage of months would have a maximum temperature of 34 degrees or higher?
This is 1 subtracted by the pvalue of Z when X = 34. So
has a pvalue of 0.9616
1 - 0.9616 = 0.0384
3.84% of months would have a maximum temperature of 34 degrees or higher
One week = 3 dolls
two weeks = 3 × 2 dolls
three weeks = 3 × 3 dolls
four weeks = 3 × 4 dolls
five weeks = 3 × 5 dolls
'w' weeks = 3 × w dolls
'w' weeks = 3w dolls
Initial number of dolls = 254 dolls
Number of dolls after 'w' weeks = 254 + 3w
