Astronauts increased in height by an average of approximately 40 mm during the Apollo-Soyuz missions, due to the absence of grav

ity compressing their spines during their time in space. To find out if something similar happens on Earth, a NASA experiment measured the heights of six men immediately before a three day bed rest. By the end of the third day, they had increased in height by an average of 14 mm, with a standard deviation of 0.66 mm. Find the 95% confidence interval for the change in height after 3 days of bed rest. Express your answer as lower bound to higher bound with one decimal place. Do not include units.

Given the sequence in the table below, determine the sigma notation of the sum for term 4 through term 15.
Naya [18.7K]
It's a geometric sequence.

4,-12,36,... \\ \\&#10;a_1=4 \\&#10;r=\frac{a_2}{a_1}=\frac{-12}{4}=-3 \\ \\&#10;a_n=a_1 \times r^{n-1} \\&#10;a_n=4 \times (-3)^{n-1} \\&#10;a_n=4 \times (-3)^{-1} \times (-3)^n \\&#10;a_n=4 \times (-\frac{1}{3}) \times (-3)^n \\&#10;a_n=-\frac{4}{3}(-3)^n

It's the sum for term 4 through term 15.

 \boxed{ \sum\limits_{n=4}^{15} (\frac{4}{3}(-3)^n)}

This is urgent, please answer!!
Serhud [2]
Answer: 23.4

Explanation: make the volumes equal each other with the ? as x. Then solve.
(12)(18)(32.5)=(25)(12)x
Divide both sides by 12
(18)(32.5)=25x
Solve left side
585=25x
Divide by 25
x=23.4
