Answer:
a) 250
b) 125
Step-by-step explanation:
For a, the answer is 250 because if 2 regions are labelled 6, and there are 6 regions, and the spinner is spun 750 times, then we will multiply 2 by 750 and divide the answer by 6.
2 x 750 = 1500
1500/6 = 250
Now, for b, the answer is 125 because 3 is the only prime number there and only one region is labelled 3. So we multiply 1 by 750 (which is 750) and divide by 6.
750/6 = 125.
a = 250
b = 125
Answer:
Step-by-step explanation:
Given
Required:
Find
Replace f(x) with y
Swap both variables
Make y the subject
Replace y with f-1(x)
6(4x + 5) = 3(x + 8) + 3
= 24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
21x + 30 = 27
21x = -3
21x/21 = -3/21
x = -1/7
Or 0.143 (3 dec)
You multiply them like you would multiply anything, but the answer would be negative because a negative times a positive equals a negative.
