Answer:
Step-by-step explanation:
<u>Given line:</u>
<u>Points on the same line:</u>
- (2a, -4a + 3) and (2b - 3, b)
<u>Substitute x and y values of both points into equation of the line and solve for a and b:</u>
- -4a + 3 = -3(2a) - 2 ⇒ -4a + 3 = -6a - 2 ⇒ 6a - 4a = -2 - 3 ⇒ 2a = -5 ⇒ a = -2.5
- b = -3(2b - 3) - 2 ⇒ b = -6b + 9 - 2 ⇒ b+ 6b = 7 ⇒ 7b = 7 ⇒ b = 1
Hi,thank you for posting your question here at Brainly.
Probability is a numerical value that represents a fraction of a whole. Since there are 4 samples indicated in row X, then there must be 4 probabilities corresponding to each. The sum of all those probabilities must equal to 1. With this information, we could already find the missing probability.
Summation of P = 1 = 0.40 + 0.20 + 0.20 + x
x = 1 - 0.4 - 0.2 - 0.2
x = 0.2 <-- missing probability
Answer:
AC = 10
Step-by-step explanation:
AC+ BC =AB
If C is the midpoint then AC = BC
AC + AC = 20
2 AC = 20
Divide by 2
2AC /2 = 20/2
AC = 10
