Explain why it is necessary to rename 4 1/4 if you subtract 3/4 from it

Mathematics

horrorfan [7]3 years ago

You would rename four and one fourth when subtracted from three fourths because when you subtract the fractions you get a different fraction for your answer.
4 \frac{1}{4}- \frac{3}{4}= 3 \frac{1}{2}
so you would said three and one half instead of four and one fourth.
Hope I helped!

Jet001 [13]

Answer:

The mean for the sampling distribution of the sample proportion is 0.29

The standard deviation for the sampling distribution of the sample proportion is 0.01435

Step-by-step explanation:

The mean for the sampling distribution of the sample proportion is always equal to the true population proportion, in this case; p = 0.29

The standard deviation for the sampling distribution of the sample proportion is calculated as;

\sqrt{\frac{p(1-p)}{n} }

Using the given values;

p = 0.29

1 - p = 0.71

n = 1000

The standard deviation becomes;

\sqrt{\frac{(0.29)(1-0.29)}{1000} } \\

The s.d becomes 0.01435

A system of linear equations with fewer equations than unknowns is sometimes called an underdetermined system. Can such a system
elena55 [62]

Answer:

No, it cannot have a unique solution. Because there are more variables than​ equations, there must be at least one free variable. If the linear system is consistent and there is at least one free​ variable, the solution set contains infinitely many solutions. If the linear system is​ inconsistent, there is no solution.

Step-by-step explanation:

the questionnaire options are incomplete, however the given option is correct

We mark this option as correct because in a linear system of equations there can be more than one solution, since the components of the equations, that is, the variables are multiple, leaving free variables which generates more alternative solutions, however when there is no consistency there will be no solution
