\text{Hey there!}

-5\frac{3}{4}-3\frac{1}{2}=?

\text{-5}\frac{3}{4}=\text{-5}\times\text{4+3}\rightarrow\text{-5}\times4=-20\rightarrow\text{-20 + 3 = -23}

\text{The denominator stays the same:}-5\frac{3}{4}=-\frac{23}{4}

\text{3}\frac{1}{2}=3\times2+1\rightarrow3\times2=6+1\rightarrow6+1=7

\text{3}\frac{1}{2}=\frac{7}{2}

\frac{-23}{7}-\frac{7}{2}=?

\text{Solve the NEWER question above}\uparrow\text{and you will see your answer}

\boxed{\boxed{\bf{Answer:Improper\ fraction:\frac{-37}{4}\ or\ Mixed\ number:-9\frac{1}{4}}}}\checkmark

Last year, the numbers of skateboards produced per day at a certain factory were normally distributed with a mean of 20,500 skat
alisha [4.7K]

Answer:

This can be solved by using the empirical rule for a normal distribution.

Step-by-step explanation:

A. The number of skateboards given is one standard deviation above the mean. Approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean. Therefore the required percentage is:

68 + 16 = 84%.

B. The given number of skateboards is two standard deviations above the mean. Approximately 95% of the data points lie within the range plus and minus two standard deviations of the mean. Therefore the required percentage is:

5/2 = 2.5%

C.The given number of skateboards is one standard deviations below the mean. Therefore the required percentage is:

16%.

Select the correct answer. In which table does y vary inversely with x?
vladimir2022 [97]

Answer:  C

<u>Step-by-step explanation:</u>

Varies inversely means xy = k

A. 1(-3) = -3

   2(-9) = -18

                     -3 ≠ -18

B. 1(-6) = -6

   2(-12) = -24

                    -6 ≠ -24

C. 1(6) = 6

   2(3) = 6

   3(2) = 6

                6 = 6 = 6      This works!

D. 1(-3) = -3

   2(2) = 4

               -3 ≠ 4

The only table that has the same k-value is option C.
