Answer:
y + 9 = 1/5(x + 8)
Step-by-step explanation:
Point-slope form: y - y₁ = m(x - x₁)
Substitute the values into the equation.
y - (-9) = 1/5(x - (-8)
y + 9 = 1/5(x + 8)

Answer = 3:1</h3>
==========================================
Work Shown
45 girls : 15 boys
45/15 girls : 15/15 boys .... divide both parts by 15
3 girls : 1 boy
This tells us there are three times as many girls as there are boys.
We write this as the ratio 3 : 1. The order of the terms is important. We cannot say 1:3 since that would imply there are more boys than girls, but it's the other way around.
The correct answer is A ($239,000)
If for one square foot it's $113.81, then for 2100 square feet it'll be:
2100 × $113.81 = $ 239,001.
This wasn't an option but the correct answer would be A ($239,000)
(-6)times 2/ 12/2
(-6) times 1/12
-.5 is the correct answer
Answer: the probability that the tires will fail within three years of the date of purchase is 0.12
Step-by-step explanation:
The average lifetime of a set of tires is 3.4 years. It means that μ = 3.4
Decay parameter, m = 1/3.4 = 0.294
The probability density function is
f(x) = me^-mx
Where x is a continuous random variable representing the time interval of interest(the reliability period that we are testing)
Since x = 3 years,
Therefore, the probability that the tires will fail within three years of the date of purchase is
f(3) = 0.294e^-(0.294 × 3)
f(3) = 0.294e^- 0.882
f(3) = 0.12
