Answer:
slope = 
, point on line = (3, - 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) is a point on the line
y + 4 = (x - 3) ← is in point- slope form
with slope m = and (a, b) = (3, - 4)
Answer:
a.) 0.1685
b.) 0.7922
Step-by-step explanation:
This question is solved by the probability distribution formula for selection which uses the combination formula to derive the answer.
If 7 out of 12 cases Of refrigerators are said to have compressor problem, then the success rate to be used in the probability distribution formula = p = 7/12 = 0.583
Probability of failure = q = 0.417
When choosing r samples from a possible n sample, then probability distribution formula is denoted by :
P(X=r) = nCr × p^n × q^n-r
a.) From possible 6 samples, if P(X=5)
P(X=5) = 6C5 × 0.583^5 × 0.417¹
P(X=5) = 0.1685
b.) P(X≤4) =1 -P(X>4) = 1 - P(X=5) - P(X=6)
P(X=5) as calculated earlier = 0.1685
P(X=6) = 6C6 × 0.583^6 × 0.417^0
P(X=6) = 0.0393.
Hence, P(X≤4) = 1- 0.1685 - 0.0393
P(X≤4) = 0.7922
