Answer:
12
Step-by-step explanation:
Given the data :
X : 10,8,18,17,7
The mean value of scores obtained can be obtained thus :
Mean = ΣX / n
n = sample size = 5
Mean = ΣX / n = (10+8+18+17+7) / 5
Mean = 60 / 5 = 12

Answer:
gradient = 9
Step-by-step explanation:
Note that is a measure of the gradient.
Differentiate y using the power rule
(a) = na
Given
y = x² + 5x - 3, then
= 2x + 5
x = 2 : = 2(2) + 5 = 4 + 5 = 9 ← gradient
