Answer:
0.5714 is the probability that a randomly selected customer will wait between 1 and 5 minutes at the delicatessen.
Step-by-step explanation:
We are given the following information in the question:
a = 0, b = 7
Then, the uniform distribution function is given by:
a) P( 1 < x < 5)
0.5714 is the probability that a randomly selected customer will wait between 1 and 5 minutes at the delicatessen.
Answer:
x=−4 and y=1
Step-by-step explanation:
Rewrite equations:
y=−2x−7;−3x+4y=16
Step: Solvey=−2x−7for y:
y=−2x−7
Step: Substitute−2x−7foryin−3x+4y=16:
−3x+4y=16
−3x+4(−2x−7)=16
−11x−28=16(Simplify both sides of the equation)
−11x−28+28=16+28(Add 28 to both sides)
−11x=44
-11x/-11=44/-11
x=−4
Step: Substitute−4forxiny=−2x−7:
y=−2x−7
y=(−2)(−4)−7
y=1(Simplify both sides of the equation)
x=−4 and y=1
Answer:
Y= 3.2b + 100
Step-by-step explanation:
That is the equation needed to find the value of b. since Omar bought the cup at the fixed price of 100 we know that no matter what the answer has to be over 100. So that becomes our Y intercept. 3.2 percent is how much the price inflates every year.
