7.4.7-T Question Help Here is a sample of amounts of weight change (kg) of college students in their freshman year: 14, 3, 1, -7, where - 7 represents a loss of 7 kg and positive values represent weight gained. Here are ten bootstrap samples: 14, 14, 14, 1}, {14, -7, 1, 14}, {14, -7, 3, 1}, {3, -7, 1, 14}, {1, 1, 1, 3}, {3, -7, 3, -7), {14, 3, -7, 1}, {-7,3, -7, 3}, { -7,1, -7,3}, {3, 14, 14, 14). © Complete parts (a) and (b) below. a. Using only the ten given bootstrap samples, construct an 80% confidence interval estimate of the mean weight change for the population. [ kg ​

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
