3 4/7 minus 2 1/5 by rounding to the nearest half
mylen [45]

Answer:

1 \frac{13}{35}

Step-by-step explanation:

3 \frac{4}{7} -  2 \frac{1}{5}

you can solve for the fractions first, but you have to give them a common denominator

\frac{20}{35}- \frac{7}{35}

= \frac{13}{35} which is in simplest form

then solve for the whole numbers

3-2=1

therefore, the answer is 1 \frac{13}{35}

What is the insverse of the function f(x) =2x+1?
goldenfox [79]
F(x) = 2x + 1

To find the inverse of a function you just need to switch the x by y or vice-versa:

-> y = 2x + 1
-> x = 2y + 1

After that you isolate the y again:

-> 2y = x - 1

-> y = (x-1)/2
-> f^-1 (x) = (x-1)/2

Answer:
f^{ - 1} (x) = (x - 1) \div 2

For a population with a mean of u = 40 and a standarddeviation of o = 8, find the z-score corresponding toeach of the following
ivann1987 [24]

Solution:

Given the mean and standard deviation;

\mu=40,\sigma=8

The z-score formula is;

z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}

(a)

\begin{gathered} x=34,n=1 \\  \\ z=\frac{34-40}{\frac{8}{\sqrt{1}}} \\  \\ z=-0.75 \end{gathered}

(b)

\begin{gathered} x=34,n=4 \\  \\ z=\frac{34-40}{\frac{8}{\sqrt{4}}} \\  \\ z=-1.5 \end{gathered}

(c)

\begin{gathered} x=34,n=16 \\  \\ z=\frac{34-40}{\frac{8}{\sqrt{16}}} \\  \\ z=-3 \end{gathered}
