Check Explanation

Step-by-step explanation:

The question isn't complete as each amount to be matched with the expression that represents its situation isn't provided

We obtain a general formula for the expressions and move forward from there.

Cost of one ticket = t dollars

Normal cost of buying n tickets for (n<10) = nt dollars

Normal cost of buying 10 tickets = 10t

But there's a discount of 5%, hence, the discount = 5% × 10t = 0.5t

Cost of buying 10 tickets = 10t - 0.5t = 9.5t dollars

Normal cost of buying n tickets for (10 < n < 20)

= (Cost of buying 10 tickets) + (cost of buying the extra tickets)

= 9.5t + (n - 10)t = nt + 9.5t - 10t = (nt - 0.5t) dollars

Cost of buying 20 tickets

= 20t - (2)(0.5t) = 20t - t = 19t dollars

Cost of buying (20 < n < 30) tickets

= nt - (2)(0.5t) = (nt - t) dollars

So, generally, cost of buying an exact k-multiple of 10 = (10kt) - (k)(0.5t) = 10kt - 0.5kt = (9.5kt) dollars

And the general price of buying n tickets, where n is associated with a k-multiple of 10 = nt - (k)(0.5t) = (nt - 0.5kt) dollars.

Basically, it's a discount of 0.5t dollars for every 10 tickets bought!

With this explanation and general formulas provided, we should be able to match any amount given with the expression that represents its situation. Thank you!

Hope this Helps!!!

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

Which statement is not true about the data shown by the box plot below?

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: $\sqrt{\frac{ {72x}^{16} }{ {50x}^{{{36} }}}} = \frac{ { \sqrt{72}x}^{ {16}^{ (\frac{1}{2}) } } }{ { \sqrt{50} x}^ {{36}^{ (\frac{1}{2}) } }}$ multiply exponents per exponent rules to get: $\frac{ { \sqrt{72}x}^{8} }{ { \sqrt{50}x}^{18} }$ remember you subtract exponents from the denominator and add exponents in the numerator so: $\sqrt{ \frac{72}{ 50}} \times ( {x}^{(8 - 18) } ) = \sqrt{ \frac{36}{25} } \times ( {x}^{ - 10} )$ simplify further: $\frac{6}{5} {x}^{ - 10} = \frac{6}{5 {x}^{10} }$ so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
Plz hurrywhat is the simplified form of ? assume x ≠ 0.
