Using the given information, the average of r and s is 35.5

<h3>Calculating Average</h3>

From the question, we are to determine the average of r and s

From the give information,

The average of p, q and 27 is 28.

That is,  

(p + q + 27)/3 = 28

p + q + 27 = 3×28

p + q + 27 = 84

p + q = 84 - 27

p + q = 57

Also,

The average of p, q, r, s and 27 is 31

That is,

(p + q + r + s + 27)/5 = 31
p + q + r + s + 27 = 5 × 31

p + q + r + s + 27 = 155

Thus,

57 + r + s + 27 = 155

r + s = 155 - 57 - 27

r + s = 71

The average of r and s is (r + s)/2

(r + s)/2 = 71/2

(r + s)/2 = 35.5

Hence, the average of r and s is 35.5

Between x = 2 and x = 3, which function has a greater average rate of change than y = 13 -x ?
Marrrta [24]
For this case what you should know is that the slope of the line can be calculated as:
 Tan x = sin x / cos x
 The lines x = 2 and x = 3 have an angle of 90 degrees with respect to the x axis:
 Tan 90 = sin 90 / cos 90 = 1/0 = inf
 Therefore, both lines have a rate of change that tends to infinity.
 answer
 Both lines have the same slope (infinity) Both are greater than m = -1

Element X is a radioactive isotope such that every 90 years, its mass decreases by half. Given that the initial mass of a sample
steposvetlana [31]

Answer:

approximately 27 grams

Work Shown:

Half life formula

y = A*(0.5)^(x/H)

where,

A = starting amount = 30 grams

H = half life period = 90 years

x = number of years that pass by = 12

y = amount left over after x years

Let's plug the values for x, A and H into the formula to find y

y = A*(0.5)^(x/H)

y = 30*(0.5)^(12/90)

y = 27.3516746567466

y = 27 .... rounding to the nearest whole number
