Answer:
x = 49/23
Step-by-step explanation:
23x=49
Divide each side by 23
23x/23 = 49/23
x = 49/23
Mean is the average number. To find mean, add all the numbers and divide by how many numbers there are.
There are 9 numbers. Divide by 9
Question 6 ⇒ C. 84.44
Median is the middle number when ordered from least to greatest. First order the numbers.
The 2 middle numbers are 10 and 11. Add them together and divide by 2
Question 7 ⇒ D. 10.5
Answer:
35 days
Step-by-step explanation:
We know that L(t) is the tangent to the line A(t) at t = 30
At t = 30:
A (30) ≈ 0.783 →(30, 0.783) = (t, A(t))
A¹ (30) ≈ -0.56
let -0.56 = M
For a linear function, a straight line equation applies which leads to
(y-y₁) = m (x-x₁) ...1
So for this problem we have;
A (t)-0.783 = -0.56 (t - 30)
when there is 0.5 pounds of grass, A (t) - 0.5, then using the equation (1)
(0.5 - 0.783) = -0.56 (t-30)
t = 35.054
≈ 35 days
