Sum of a geometric sequence for a1=first term and n=which one and r is common ratio is
S_n= \frac{a_1(1-r^n)}{1-r}
so
a1=1 students
r=4
n=5
S_n= \frac{1(1-4^5)}{1-4}
S_n= \frac{(1-1024)}{-3}
S_n= \frac{-1023}{-3}

The selling price for houses in a neighborhood in West Richland, WA have an approximately normal distribution with a mean sellin
Liula [17]

The probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753

First, we need to find the z-score and this is expressed according to the formula;

z=\dfrac{x-\mu}{\sigma}

x is the sample space

\mu is the mean value

\sigma is the standard deviation

Given the following parameters

Mean = $275,000

Standard deviation = $10,500

If the true mean is $273,000, then;

z=\dfrac{273,000-275000}{10,500} \\z = \frac{-2000}{10500}\\z= -0.1905

If the true mean is $277,000

z=\dfrac{277,000-275000}{10,500} \\z = \frac{2000}{10500}\\z= 0.1905

This means that the z-score is between -0.1095 and 0.1095

Pr( -0.1095 ≤ z ≤ 0.1095)

According to the z table, the probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753

A small company's net income for the first six months of the year was 76,500 for the last six months it was 100,000 what is the
Stells [14]

Answer:

The ratio of net income in the first 6 months, to the last six months is $76,500 / $100,000. This simplifies intuitively as follows:

76500/100000

Dividing by 100: 765/1000

Dividing by 5: 153/200

The denominator 200 is only divisible by the prime numbers 2 and 5, and since the numerator 153 is not divisible by either 2 or 5, this means that this is in simplest form, and the final answer is 153/200.
