Answer:

The number is ;

25/11

Step-by-step explanation:

$Let- the -unknown- number- be ; x\\2\frac{1}{5} \times x =5\\\\\frac{11x}{5} =5\\Cross-Multiply\\11x = 25\\Divide- both-sides-of-the-equation -by ; x\\\frac{11x}{11} =\frac{25}{11} \\x = 25/11\\\\x = 2\frac{3}{11}\\$

If f(x) = 4x - 3, what is (f^-1 o f)(10)?

RSB [31]

F(x)=(4x-3)^-1(10))
(-4x+3(10))
(-4x(30))
i think that's how you would solve it i can't quite remember if you substitute the x with the 10 but if you do it would be
f(x)=4(10)-3
40-3
37
but im pretty sure it's the first way.

According to the National Postsecondary Student Aid Study conducted by the U.S. Department of Education in 2008, 62% of graduate

Ronch [10]

The standard error for the distribution of sampling proportions will be 0.0686.

<h3>What is standard error for the distribution of sampling proportions?</h3>

In mathematics, the difference between a data set and the populace's true average is known as primary data deviation from the mean.

According to the National Postsecondary Student Aid Study conducted by the U.S.

Department of Education in 2008, 62% of graduates from public universities had student loans.

We randomly select 50 students at a time.

Then the standard error for the distribution of sampling proportions will be

$\rm Standard\ error = \sqrt{\dfrac{p(1-p)}{n}}\\\\Standard\ error = \sqrt{\dfrac{0.62(1-0.62)}{50}}\\\\Standard\ error = 0.0686$

More about the standard error for the distribution link is given below.
