Step-by-step explanation:
You will set up a portion tha put 35% over a 100 and 1270.75 on top of the other portion and cross multiply and divide .
Answer:
<h2>5x - y = 3</h2><h2>5x - y - 3 = 0</h2>
Step-by-step explanation:
y = 5x - 3 <em>it's a slope-intercept form</em>
<em />
y = 5x - 3 <em>subtract 5x from both sides</em>
-5x + y = -3 <em>change the signs</em>
5x - y = 3 <em>it's a standard form</em>
<em />
5x - y = 3 <em>subtract 3 from both sides</em>
5x - y - 3 = 0 <em>it's a general form</em>
Answer:
1.967 × 10⁻¹¹
Step-by-step explanation:
This is a conditional probability problem
Probability that a 12 year old leaf blower works for 5 more years = Probabilty that a leaf blower works for 17 years, given that it has worked for 12 years = P(17|12)
P(17|12) = P(17 n 12)/P(12)
P(17 n 12) = P(17)
Exponential random variable is given as
f(x) = λ e^(-λ.x)
λ = rate parameter = 5 years per blower
x = variable whose probability is required = 17
f(17) = 17 e^(-5×17)
f(17) = 17 e⁻⁸⁵ = 2.067 × 10⁻³⁶
f(12) = 12 e^(-5×12)
f(12) = 12 e⁻⁶⁰ = 1.051 × 10⁻²⁵
P(17|12) = (2.067 × 10⁻³⁶)/(1.051 × 10⁻²⁵)
P(17|12) = 1.967 × 10⁻¹¹
