The time that it takes to service a car is an exponential random variable with rate 1. (a) If Lightning McQueen (L.M.) brings hi

s car in at time 0 and Sally Carrera (S.C) brings her car in at time t, what is the probability that S.C.’s car is ready before L.M.’s car? Assume that service times are independent and service begins upon arrival of the car. Be sure to: 1) define all random variables used. 2) explain how independence of service times plays a part in your solution. 3) show all integration steps. (b) If both cars are brought in at time 0, with work starting on S.C.’s car only when L.M.’s car has been completely serviced, what is the probability that S.C.’s car is ready before time 2?

Helppppp please.. How do I do this?!? please and than you
Harman [31]

Answer:

  -7/3

Step-by-step explanation:

When finding slope from a graph, I always look for places where the graph crosses grid intersections. One of these is the y-intercept, (0, 40).

You have to go quite some distance to find another. It looks to me like the next grid crossing is at (30, -30). At this point, you can do either of two things:

  • find the ratio of grid squares
  • use the slope formula

What you want to calculate is the ratio of the change in vertical height (rise) to the change in horizontal distance (run). If you use grid squares, you need to make sure the grid has the same number of units horizontally as vertically. (Here a grid square is 10 units in each direction, so we're OK on that point.)

We have observed that the line falls 7 grid squares vertically for a change of 3 grid squares to the right. So, the slope using grid squares is ...

  m = rise/run = -7/3

Using the slope formula, we calculate the slope to be ...

  m = (y2 -y1)/(x2 -x1)

  m = (-30 -40)/(30 -0) = -70/30 = -7/3

The slope of the line is -7/3.

A right rectangular pyramid is sliced vertically (down) by a plane passing
Anton [14]

A right rectangular pyramid when sliced vertically, the  shape of the cross-section is known as Triangle.

<h3>What is A triangle?</h3>

This is known to be a kind of shape that is said to be in  a closed form and it is also known to be a 2-dimensional shape that has 3 sides, 3 angles, and also 3 vertices.

Note that when the when the right rectangular pyramid is sliced vertically (down) by a plane passing through the  of the pyramid, the new shape of the cross-section is a triangle.

See full question below

Type the missing number in this sequence: 4, , 144, 864, 5,184, 31,104
rosijanka [135]

The missing number in the given series is 24.

<h3>What is missing number in the given sequence?</h3>

Missing numbers are the numbers that have been missed in the given series of a number with similar differences among them. The method of writing the missing numbers is stated as finding similar changes between those numbers and filling the missing terms in the specific series and places.

Given the series,

4, ?, 144, 864, 5184, 31104

Multiplying with 6 in each term in the given sequence.

4×6 = 24

24×6 = 144

144×6 = 864

864×6 = 5184

5184×6 = 31104

Following the above sequence, we get the 2nd term is 24.

Hence the missing number is 24.
