Solve 3/x^2-8=2 Help pleaseeeee

Answer: x=\sqrt{\frac{3}{10}}=0.54

Step-by-step explanation:

We have the following equation and we have to find x:

\frac{3}{x^{2}}-8=2

Grouping similar terms:

\frac{3}{x^{2}}=2+8

\frac{3}{x^{2}}=10

Isolating x^{2}:

\frac{3}{10}=x^{2}

Applying square root on both sides of the equation:

\sqrt{x^{2}}=\sqrt{\frac{3}{10}}

Finally:

x=\sqrt{\frac{3}{10}}=0.54

Which data set is the farthest from a normal distribution?
Rudik [331]

Answer:

(C)0.9, 1.0, 1.0, 1.1, 1.1, 1.1, 1.2, 1.2, 1.3

Step-by-step explanation:

In (A), (B), (D) and (E) options, all have similar set of numbers and ranges between 2 to 10. Moreover these contains the whole numbers, so when we find mode, median and mean of these data sets, they will follow the same path.

But in (C), the data values involves decimals and are not the part of the other data values and it goes from 0.9-1.3, thus making them farthest from a normal distribution when mean, mode and median are calculated.

Thus, option (C) is correct.

Part 1= You are shopping for a shirt, and you want to get the best deal. You go to two stores, the first of which is JCPenney. W
DedPeter [7]

Answer:

Macy’s

Step-by-step explanation:

let’s find the cost of each shirt

JCPenny’s: 14.99 x 0.80 = $11.99

                   11.99 x 1.06 = $12.70

                   The final cost of the JCPenny shirt is $12.70

Macy’s: 17.99 x 0.65 = $11.69

             11.69 x 1.07 = $12.51

             The final cost of the Macy’s shirt is $12.51

$12.51 is less than $12.70

So, the Macy’s shirt is the better deal :)
