106% of $x = $7.95
In other words,
of $x = 7.95
Multiplying both sides of the equation by
of x = 7.95 *
=> x =
=> x =
=> x = 7.5

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:
Answer:
100 persons
Step-by-step explanation:
Total amount for marriage = $10000
University charges for wedding ceremony (chairs, tents, red carpet, and flowers) = $2,000 - $150 = $1850
Left amount (after deducting the university charges from total amount)
= $10000 - $1850
= $8150
Now, per person reception cost = $80
Therefore, no. of persons that can attend their wedding = = 101.875 ≈ 100.
