Answer:
The mean score in the maths test for class B was 12.41 points.
Step-by-step explanation:
Given that Class A has 12 pupils and class B has 29 pupils, and both classes sit the same maths test, and the mean score for class A is 52 while the mean score for both classes is 24, to determine what is the mean score in the maths test for class B the following calculation must be performed:
52 x 12 + X x 29 = 24 x (12 + 29)
624 + 29X = 24 x 41
624 + 29X = 984
29X = 984 - 624
X = 360/29
X = 12.41
Therefore, the mean score in the maths test for class B was 12.41 points.
Answer:
Is this two different lines or is that what goes first?
Step-by-step explanation:
Answer:
y = 3/2 x + 9
Step-by-step explanation:
take the two points and find slope :
12 - 3 / 2 - (-4) = 3/2
then use the slope and one of the points to find the y-intercept :
y = 3/2 x + b
3 = 3/2 * (-4) + b (Substitute)
3 = -6 + b (Multiplication)
3 + 6 = -6 + b + 6 (Addition)
b = 9
so, your final slope-intercept equation is :
y = 3/2 x + 9
