Answer:
31 raffle tickets
Step-by-step explanation:
23.25 divided by 0.75 = 31
1, 2, 4, 8, 16 ...
a = 1
d = 8/4 = 2
Sn = n/2(2a + (n-1)d) = 30(2 + (29×2)) = 30(60) = 1800
Ans = $1,800 ...//
Answer:
0.430
Step-by-step explanation:
Product has four parts :
For proper functioning, each part must function :
Let the 4 parts be:
A, B, C and D
Proper functioning probability :
A and B = 0.79
C and D = 0.83
For proper functioning :
P(A) * P(B) * P(C) * P(D)
0.79 * 0.79 * 0.83 * 0.83
= 0.42994249
= 0.430
Assuming each line goes up by 1. we basically need to find a number that goes by rise/run. to get to the next point we need to go up 1, then to the left by 3. notice the slope is negative so we need to add a negative integer.
answer:
-1/3 (C)
hope this helps! :D
