Answer:

k = 23% profit on sale price is needed to ensure 30% profit on cost price

Step-by-step explanation:

Let sale price be = s , Profit = k% of s

Let cost price be = 100 , Profit = 30% of c

Cost price (c) + profit (p)  = Sale price (s)

c + 0.3c = s

1.3c = s

Profit as a percentage of sale = (Profit / Sale) x 100

= (0.3c / 1.3c) x 100

= 23%

Evaluate the expression without using a calculator<br><br> Tan(arccos3/4)

Answer:

  (√7)/3

Step-by-step explanation:

The relationship between tangent and cosine is ...

  tan(α) = √(1/cos(α)² -1)

The cosine of the angle is given as 3/4, so the tangent is ...

  tan(arccos(3/4)) = √(1/(3/4)² -1) = √(16/9 -1) = √(7/9)

  tan(arccos(3/4)) = (√7)/3

Suppose the scores of seven members of a women’s golf team are 68, 62, 60, 64, 70, 66, and 72. Find the mean, median, and midran
grin007 [14]
Mean - add up all of the scores, and divide it by the number of members:

68 + 62 + 60 + 64 + 70 + 66 + 72 = 462
462 / 7 = 66

ANSWER: The mean is 66

Median - write out all the numbers in order, and select the middle value:

60, 62, 64, 66, 68, 70, 72

ANSWER: As you can see, 66 is the middle value.

Midrange - find the mean (average) of the smallest and largest number:

Largest number: 72
Smallest number: 60

Midrange:   72 + 60 = 132
                     132 / 2 = 66

ANSWER: So the midrange is 66
