Answer:
Step-by-step explanation:
a to b represents a quarter of the line segment in order to get to %100 we need to multiply 2in by 4.
2x4=8
You want to get familiar with what the slope-intercept form equation means. even though the discussion board covers some of this... slope-intercept is y = mx + b, and in it, x and y are a point on your graph (x, y), m is the slope, and b is your y-intercept. in word problems, any constant will typically be b.
but, really, to answer this word problem, you don't have to think so hard about y = mx + b. just read the problem and bring your information together:
"the venue will cost $1500 to rent for an evening"
"$25 per person"
so they only gave you two bits of information, and you just have to decide where they fit. if the venue costs $1500 for an evening, that's a fixed cost--the 1500 isn't going to go up or down depending on the number of people at the charity event. it stays. you're paying 1500 regardless, even if 2 people show up. because the discussion board states that b should represent your starting amount, you're automatically $1500 in the hole, because you have to spend that much to get the venue. you will, however, write it as a positive integer, because the question wants you to calculate the total cost, by my understanding--you're adding the cost of the people with the cost of the venue.
$25 is not a fixed amount. if it's $25 per person, then if 2 people come, it costs $50, if 3 people arrive, it costs $75. this cost is dependent upon the number of people, which you can call "x"
with that information, write any other equation you would for a word problem:
y = 25x + 1500
that's your equation, and it just so happens that this equation is in y = mx + b format. the x-value represents the number of people who show up for the charity; the y-value represents the overall cost.
and you need three solutions for this equation--which, luckily, is a quick and easy process!! choose an x-value and solve for y.
y = 25x + 1500
when x = 1...
y = 25(1) + 1500
y = 25 + 1500
y = 1525
ordered pair: (1, 1525)
when x = 2...
y = 25(2) + 1500
y = 50 + 1500
y = 1550
ordered pair: (2, 1550)
when x = 3...
y = 25(3) + 1500
y = 75 + 1500
y = 1575
ordered pair: (3, 1575)
i hope that helped!!
I would estimate around 6 because say it was 6.5 and 3 then it would around the square root of like 31 and that is rounding down a lot so we would bump it up to somewhenre around 35 so the side would be around 5.8-6
I’m guessing you want oh know what x and y are?
If so isolate the variable and do the inverse of the operation
If not please correct me ^^
Answer:
X=1, P = 0.091
X=2, P = 0.124
X=3, P = 0.115
X=4, P = 0.378
X=5, P = 0.264
X=6, P = 0.028
Step-by-step explanation:
To calculate the probability distribution of X, first we have to define the sample space.
In this case X=1,2,3,4,5,6. This are the values that X can take.
The probability is calculated as equal to the relative frequency of each of the values.
For X=1, P = 364/4000 = 0.091
For X=2, P = 496/4000 = 0.124
For X=3, P = 460/4000 = 0.115
For X=4, P = 1512/4000 = 0.378
For X=5, P = 1056/4000 = 0.264
For X=6, P = 112/4000 = 0.028
