Step-by-step explanation:
20a + 158+6c=you will expand the brackets
= so it is 120+60+48
20a+158+6c=120+60+48
20a+ 6c=120+60+48-158
20a+6c=70
20a divide by 20+6c divide by 6 on both side
a + c = 0.58
Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, - 4) and (x₂, y₂ ) = (- 6, - 2)
m = 
= 
= -
The answer is n=40 and that’s because bxndndns
Total Sample space = 10
Probability that 1 number is selected P(any Number) =1/10
Answer D is the only one that generated a probability of 40%
Proof: P(0, OR 1, OR 2, OR 3) = P(0) + P(1) + P(2) + P(3)
P(0) + P(1) + P(2) + P(3) = 1/10 + 1/10 + 1/10 + 1/10 = 4/10 or 40%
