<u>Answer:</u>
<u>The values of x and y are:</u>
- x = 6
- y = 15
<u>Step-by-step explanation:</u>
<u>We know 6y = 5x + 4y = 90°. Now, let's solve.</u>
- => 6y = 90
- => y = 90/6
- => y = 15
- => 5x + 4(15) = 90
- => 5x + 60 = 90
- => 5x = 30
- => x = 30/5
- => x = 6
<u>Hence, the values of x and y are:</u>
- x = 6
- y = 15

Answer:
95.64% probability that pledges are received within 40 days
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 is the probability that pledges are received within 40 days
This is the pvalue of Z when X = 40. So
has a pvalue of 0.9564
95.64% probability that pledges are received within 40 days
