Answer:
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:
Use the information on the right to find the z-score of a 2,500 g baby.
This is Z when X = 2500. So
H(x) would be (x - 3)(x + 10)
= x^2 + 7x - 30
Answer:
1/2 mile.
Step-by-step explanation:
There 4 1/4 hours in 1 hour so
the answer is 4 * 1/8
= 4/8
= 1/2 mile.
Gain percentage made by Mr William by selling the table at Rs. 1050 is 12.30%.
<h3><u>Solution:</u></h3>
Given that
Mr. William bought an old table for RS 850
Mr. William spent 1/10 of the cost price on its repairs.
Mr. William sold the table for Rs 1050.
Need to determine gain or loss percent.
Let’s first calculate total money spent by Mr William on Table
Total money spent by Mr William on Table = Amount at which Mr. William bought an old table + amount spent on repairs
So Total money spent by Mr William on Table = 935
Money generated by selling the table = Rs 1050
As Money generated by selling the table is more that Total money spent by on Table so there is a gain.
Gain by selling the table = Money generated by selling the table - Total money spent by Mr William on Table
= 1050 – 935 = 115
Hence gain percentage made by Mr William by selling the table at 1050 is 12.30%.
