Answer:

(x=6) is less than 18 which would give you the cost of the current plan

Step-by-step explanation:

If you take six, first you must multiply 4.50 by 6, ($27) then add it, to $94, giving you $121. Now we have to find which phone will give us the same cost, for this I choose 18. if you do 18 x 4.50, you get $81, and if you add this to 94, it gives you 175.

Calculus help??????
katen-ka-za [31]
f(x)=\ln x\implies f'(x)=\dfrac1x
g(x)=x^2-1\implies g'(x)=2x

You have 2x^2>1 for all x\ge1, and dividing by x gives 2x>\dfrac1x, or g'(x)>f'(x). By the racetrack principle, then, it follows that g(x)>f(x).

A data set includes the following grades: 98, 94, 93, 82, 61, 80. Suppose that 61 is removed from the data. How is the median af
puteri [66]

Answer:

<u>If we remove 61 from the data set, the median changes from 87.5 to 93.</u>

Step-by-step explanation:

1. Let's calculate the median of the original data set:

Median = (3rd term + 4th term)/2 because the number of terms are even and our median mark is the average of the two middle marks, in this case, 82 and 93.

Median = (82 + 93)/2

Median = 87.5

2. Let's calculate the median of the data set removing 61:

Median = 3rd term because our median mark is the middle mark, in this case, 93. It is the middle mark because there are 2 scores before it (80 and 82) and 2 scores (94 and 98) after it.

Median = 93
