Step-by-step explanation:
Still waiting for the server? How does your web browser get a file from the
Internet? Your computer sends a request for the file to a web server, and the web
400 server sends back a response. Let Y = the amount of time (in seconds) after the
start of an hour at which a randomly selected request is received by a particular
web server. The probability distribution of Y can be modeled by a uniform density
curve on the interval from 0 to 3600 seconds. Find the probability that the request
is received by this server within the first 5 minutes (300 seconds) after the hour.
Answer:
Your computer sends a request for the file to a Web server, and the Web server sends back a response.
Step-by-step explanation:
Using the uniform distribution, it is found that there is a 0.0833 = 8.33% probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour.
----------------------------------
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
The probability distribution of Y can be modeled by a uniform density curve on the interval from 0 to 3600 seconds, thus [tex]a = 0, b = 3600[/tex].
Probability in the first 5 minutes(300 seconds) is:
[tex]P(X < 300) = \frac{300 - 0}{3600 - 0} = 0.0833[/tex]
0.0833 = 8.33% probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour.

An online shopping club has 13000 members when it charges $7 per month for membership. For each $ monthly increase in membership fee, the club loses approximately 500 of its existing members. Write and simplify a function R to represent the monthly revenue received by the club when x represents the price increase.
Hint: Monthly revenue = # members•monthly fee
Just a answer with work will do, ill brainliest the best one.
Answer:
The function is: [tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]
Step-by-step explanation:
Total members=13000
Membership charge per month=$7
Increase in Membership charge per month=$1
For each $1 monthly increase in membership fee, the club loses approximately=500 members
For 1 month, 1 dollar decrease is 500 × 1
For x months, the decrease in the members is 500 × [tex]x[/tex] =[tex]500x[/tex]
The increase in membership fee is 7 + [tex]x[/tex]
After that,
Monthly revenue = Number of members × Monthly fee
Monthly revenue = [tex](13000-500x)[/tex] × [tex](7 + x)[/tex]
[tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

Step-by-step explanation:
use the whole part percent to work out answer
so its x/500 = 3/100 cross multiple 500x3= 1500 then you divide 1500 by 100 which equals 15
it looks like this kinda its hard to put on here
x = 3

so thats where u cross multiply the 500*3=1500 then divide 1500/100= 15

Answer: (x,y) -> (x,-y)
Step-by-step explanation:
If you take any point, for example (-1,1) from the blue shape, you have to multiply the y value by -1 to get to (-1,-1) for the red shape. You can test it out with any point on the two figures.
Also, by looking at it, you can see that it is a reflection over the x axis and a reflection over the x axis always just multiplies the y value by -1.

The circle below has a radius of 3 units . Find the area of the circle. Use 3.14 for π.
A=πr2=π×r×r
i well give u 10 points
Answer:
28.26 units
Step-by-step explanation:
We know the radius of the circle is 3 units, so we'll end up plugging that into the formula.
A = π(3^2) or A = π * 3 * 3
When you substitute pi for 3.14, you'll end up getting 28.26 units.

Which triangle is similar to △ABC if sin(A) = One-fourth, cos(A) = StartFraction StartRoot 15 EndRoot Over 4 EndFraction, and tan(A) = StartFraction 1 Over StartRoot 15 EndRoot EndFraction?
Answer:
ΔXYZ
Step-by-step explanation:
Trigonometric identities are equations which are true for right angled triangles. They are:
sin(A) = opposite / hypotenuse, cos(A) = adjacent / hypotenuse, tan(A) = opposite / adjacent.
Given triangle ABC with ∠A with side BC opposite to the angle, ∠B with side AC opposite to the angle, ∠C with side AB opposite to the angle.
sin(A) = opposite / hypotenuse = BC / AC = 1/4
BC = 1, AC = 4
cos(A) = adjacent / hypotenuse = AB / AC = √15 / 4
AB = √15
tan(A) = opposite / adjacent = BC / AB = 1 / √15
Two triangles are said to be similar if the ratio of their corresponding sides are in the same proportion.
ΔXYZ and ΔABC are similar because the ratio of their corresponding sides are in the same proportion.
For adjacent side; XZ / AB = 6√15 / √15 = 6
For opposite side; YZ / BC = 6/1 = 6
For hypotenuse side; XY / AC = 24 / 4 = 6

Answer:
x= .5 (not 100% sure but I think that's right)
Step-by-step explanation:
2x = 1
x= .5
Answer:
x=1.5
Step-by-step explanation:
5x + 2 = 3x + 3
subtract 2 from both sides
5x + 2 - 2 = 3x + 3 - 2
simplify
5x = 3x + 1
subtract 3x from both sides
5x - 3x = 3x + 1 - 3x
2x = 1
divide both sides by 2
[tex]\frac{2x}{2}[/tex]=[tex]\frac{1}{2}[/tex]
simplify
x=[tex]\frac{1}{2}[/tex]
[tex]\frac{1}{2}[/tex]/1.5
