Answer:
if u divide it then slop it u will get your answer
Answer:
Step-by-step explanation:
You will find that this "rule" is a linear function; its graph is a straight line.
The trick here is to determine the slope and y intercept of the str. line that goes through these points (2,3), (4,4) and (6,5), IF such a line exists.
The slope of the line segment connecting (2,3) and (4,4) is
4-3
m = -------- = 1/2
4-2
5-4
The slope of the line connecting (4,4) and (6,5) is m = ------ = 1/2
6-4
Since both slopes are the same, this IS a linear function.
Let's find its equation (rule):
Use the point-slope formula for the str. line:
m = slope = 1/2, and the point could be any of the 3 given points. Let's use (2,3). Then,
y - 3 = (1/2)(x - 2), or 2y - 6 = x - 2, or 2y = x - 2 + 6, or 2y = x + 4.
This could be written in "standard form" as -x + 2y =4, or we could solve for y and end up with
y = (1/2)x + 2 (which, as you can see, has a slope of 1/2).
Answer:
the expected value of this raffle if you buy 1 ticket = -0.65
Step-by-step explanation:
Given that :
Five thousand tickets are sold at $1 each for a charity raffle
Tickets are to be drawn at random and monetary prizes awarded as follows: 1 prize of $500, 3 prizes of $300, 5 prizes of $50, and 20 prizes of $5.
Thus; the amount and the corresponding probability can be computed as:
Amount Probability
$500 -$1 = $499 1/5000
$300 -$1 = $299 3/5000
$50 - $1 = $49 5/5000
$5 - $1 = $4 20/5000
-$1 1- 29/5000 = 4971/5000
The expected value of the raffle if 1 ticket is being bought is as follows:
Thus; the expected value of this raffle if you buy 1 ticket = -0.65
Answer:
The speed of the jet is
Step-by-step explanation:
The speed traveled by the jet can be found using the relationship between distance and time. Because the problem gives the values for distance and time, they must be replaced in the equation and in this way the requested speed will be found.
1. Write the general equation for the speed:
2. Replace the values of distance and time on the general equation for the speed and make the mathematical operations:
Therefore the speed of the jet is
