(x - 4)(x - 3) + (2 - x)(x - 1)
= x² - 3x - 4x + 12 + 2x - 2 - x² + x
= x² - x² -3x - 4x + 2x + x +12 - 2
= 0 -4x +10
Answer: -4x + 10
Naguguluhan ako sa tanong mo po
Answer :
0.2322
Step-by-step explanation:
Proportion, p of those who used e - ticket to get boarding pass = 112 / 280 = 0.4
p = 0.4
1 - p = 1 - 0.4 = 0.6
Number of samples, n = 8
P(x = 4)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 4) = 8C4 * 0.4^4 * 0.6^4
P(x = 4) = 70 * 0.0256 * 0.1296
P(x = 4) = 0.2322432
P(x = 4) = 0.2322
Answer:
1464 Students
Step-by-step explanation:
10% increase of 1000 = 1100 year 1
10% increase of 1100 = 1210 year 2
10% increase of 1210 = 1331 year 3
10% increase of 1331 = 1464 year 4
Answer:
1. slope= 3/4x Y-intercept= 7
2. slope= 5x Y-intercept=8
3. slope= -2x Y-intercept=0
4. slope= 0 Y-intercept=12
