<h3>Answer: Choice C</h3><h3>16, 22, 22, 25, 26, 26, 26, 34, 35, 39, 42, 42, 50, 72</h3>

==============================================================

Explanation:

The first row has a stem of 1 and a leaf of 6. The stem and leaf combines to 16. For this problem, the stem will always be the tens digit while the leaf values will be the units digit. If there are multiple leaves for a given row, then we use the same stem value.

In row 2, we have "2" as the stem and multiple leaves. The first three leaves for this row are {2, 2, 5}. They pair up with the stem to form the values 22, 22, 25.

So far the data set is 16, 22, 22, 25. Only choice C has this sequence of values at the start of it. Choice B comes close, but it does not have a second copy of 22. So we cross choice B off the list. Choice D is off the list because the first value '5' is not represented on the stem and leaf plot (the stem would be 0 to represent the value 05 which is just 5). Choice A is false for similar reasons.

Convert a markup of 15% on selling price to its equivalent markup on cost.

spayn [35]

Answer:

option: D is correct. ( (D) a markup of 15% on selling price is equivalent to a 85% markup on cost ).

Step-by-step explanation:

" Markup is the percentage difference between a product's cost and its selling price "

Since we are asked to Convert a markup of 15% on selling price to its equivalent markup on cost.

As there is a markup of 15% on selling price. Hence the cost of the product would be (100-15)%=85% of the selling price.

<em>Hence, a markup of 15% on selling price is equivalent to a 85% markup on cost.</em>

<em>Hence, option D is true.</em>

Given g(x)=-x-3, solve for x when g (x) =6

LiRa [457]

Answer:

x = - 9

Step-by-step explanation:

Given g(x) = - x - 3 and g(x) = 6, then equate, that is

- x - 3 = 6 ( add 3 to both sides )

- x = 9 ( multiply both sides by - 1 )

x = - 9

Math hw graded on accuracy pls help!!

lubasha [3.4K]

Answer:

see below

Step-by-step explanation:

Putting n=1 into the formulas eliminates the first two choices, since they evaluate to 3.57 and 0.85, respectively, not 4.2.

Putting n=2 into the formula eliminates the third choice, because you know that 4.2(0.15) < 3.57 without even using a calculator.

The only viable choice (and the correct choice) is the last one.

, find a1 and d. 34, 40, 46, 52, 58, 64

yulyashka [42]

Answer:

a1 = 34, d = 6.

Step-by-step explanation:

a1 = the first term = 34.

To find d subtract: 2nd term - first term , third term - second term and so on.

d = 40 - 34 = 6.

Also 46-40 = 6

WE get the same value 6 for the other given terms.

6 is added to each term to get the next term
