The probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour is 0.0833 or 8.33%.
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 server sends back a response.
For one particular Web server, the time X (in seconds) after the start of an hour at which a randomly selected request is received has the uniform distribution shown in the figure.
The probability of finding value less than the X is,
[tex]P(X < x)=\dfrac{x-a}{b-a}[/tex]
Here, a and b are two bonds of uniform distribution.
The probability distribution of X can be modeled by a uniform density curve on the interval from 0 to 3600 seconds, as shown in the given figure.
The probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour has to be found out. Thus,
[tex]P(X < x)=\dfrac{300-0}{3600-0}\\P(X < x)=0.0833\\P(X < x)=8.33\%[/tex]
Thus, the probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour is 0.0833 or 8.33%.

Find the volume of a cone that has a radius of 8 meters and a height of 9 meters. Use 3.14 for pi
Answer:
Volume of cone = 1/3 Area of base × height
= 1/3× πr² × h
= 1/3×3.14×8²×9
= 602.88 m³
Answer:
602.44 cubic meters[tex] \: [/tex]
Step-by-step explanation:
In the question, it is given that a cone has a radius of 8 meters and a height of 9 meters and we have to find the volume of the cone.
[tex] \: [/tex]
To Find the volume of the cone, we must know this formula :
[tex] \\{\longrightarrow{ \qquad{\underline{\boxed {\pmb{\frak { Volume_{(cone) }= \dfrac{1}{3} \: \pi {r}^{2}h }}}}}}} \\ \\[/tex]
Where,
r refers to the radius of the cone.h refers to the height of the cone.Now, we will substitute the values in the formula :
[tex] \\ {\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times 3.14 \times {(8)}^{2} \times 9 }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times 3.14 \times 64 \times 9 }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times 3.14 \times 576 }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times 1808 .64 }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1808 .64}{3} }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\frak { Volume_{(cone) }= 602.88 }}}}}}} \\ \\[/tex]
Therefore,
The volume of the cone is 602.88 m³On the number line below, the numbers a and b are the same distance from 0. What is a + b? Explain how you know.
If we start at zero and move a units to the right, and then move the same number of units to the left, we will be back at 0. We can also represent this symbolically. Since a and b are the same distance from zero but are on opposite sides of zero, we know that they are opposites, so b = -a
Answer:
If we start at zero and move a units to the right, and then move the same number of units to the left, we will be back at 0. We can also represent this symbolically. Since a and b are the same distance from zero but are on opposite sides of zero, we know that they are opposites, so b = -a.

A college student was offered two different summer jobs. Job A would last 20 weeks and pay $300
per week with weekly raises of $10. Job B would last 5 months and pay $1200 per month, with monthly
raises of 10% of the previous month's salary. How much more would the college student earn by
accepting Job A?
Answer:
600yan lang po thank you
Answer:
$574
Step-by-step explanation:
[tex]\begin{aligned}\text { week } 1=w_{1} &=300 \\w_{2} &=300+10=310 \\w_{3} &=310+10=320=300+2 \times(10)\end{aligned}[/tex]
It’s obvious here that we add 10 each time to get the next week’s payment so we Are dealing an arithmetic sequence where its first term is 300 and its
Common difference is 10
Then In the twentieth week the payment will be :
[tex]\begin{aligned}W_{20} &=w_{1}+(20-1) \times(10) \\&=300+19 \times(10) \\&=490\end{aligned}[/tex]
Now we apply the formula for the sum of Consecutives terms of an arithmetic sequence :
[tex]\begin{aligned}S_{1} &=20 \times\left(\frac{w_{1}+w_{20}}{2}\right) \\&=20 \times\left(\frac{300+490}{2}\right) \\&=7900\end{aligned}[/tex]
Now let move on to Job B:
[tex]\\\\\begin{aligned}\text { month1 }=& m_{1}=1200 \\m_{2} &=1200+1200 \times \frac{10}{100}=1200 \times(1,1)=1320 \\m_{3} &=m_{2} \times(1,1)=\left[m_{1} \times(1,1)\right] \times(1,1)=m_{1} \times(1,1)^{2} \\m_{4} &=m_{1} \times(1,1)^{3} \\m_{5} &=m_{1} \times(1,1)^{4}\end{aligned}[/tex]
It’s obvious here that we multiply by (1.1) each time to get the next month’s payment so we Are dealing a geometric sequence where its first term is 1200 and its Common ratio is 1.1
Now we apply the formula for the sum of Consecutives terms of an geometric sequence :
[tex]\begin{array}{l}S_{2}=m_{1} \times\left(\frac{1-1,1^{5}}{1-1,1}\right) \\\approx 7326\end{array}[/tex]
Finally we can say confidently say that he would earn more :
7900 - 7326 = $574.

-y > -4x - 3
Multiply by -1 remember when multiplying (or dividing) by a negative number you must REVERSE the inequality symbol.
y < 4x + 3
Your line looks great, but make it dashed. And then the shading will be below the dashed line. This creates the solution set in the triangular area in the middle bottom of the graph. The point they are asking for is not the point of intersection, it is any point in the bottom triangle, which is the doubly shaded solution set area. Use (0, -5) for example.
Jerry hiked along a path. From his starting position, he hiked downhill to a valley where the elevation dropped 25 meters below his starting position. Then, he hiked up to a hill that was 40 meters higher than the valley.
The following equation describes this situation.
-25 + 40 = 15
CHOOSE 1 ANSWER
1. Jerry hiked a total of 15 meters
2. the hill was 15 meters higher than the elevation of his starting point
3. None of the above
Answer:
15 represents where Jerry is after the elevation dropped 25 meters and then rose 40 meters.
Step-by-step explanation:
It's given that Jerry hiked downhill to a valley where the elevation dropped 25 meters below his starting position. Then, he hiked up to a hill that was 40 meters higher than the valley
Hiked downhill = 25 meters
Hiked up = 40 meters
The given equation is
Here, hiked downhill represented by negative sign and hiked up resents by positive sign.
So, 15 represents that Jerry hiked up 15 meters from his starting position.
(2, the hill was 15 meters higher than the elevation of his starting point)
Answer:
2.
Step-by-step explanation:
The hill was -25 + 40 = 15 meters highe than starting point.

I need answers with explanations for each one.
Step-by-step explanation:
the sum of all angles around a single point on one side of a line is always 180° (a line can always be seen as the diameter of an imaginary circle, so each side corresponds to 180°).
the angles on one side of a line crossed by a second line are mirrored but otherwise exactly the same as on the other side of the line.
a parallel line crossing a third line must have the exact same angles with this third line as the other parallel line. otherwise they would not be parallel. you can say a parallel line mimics the exact same behavior as the other line it is parallel to.
so,
c = 180 - 35 = 145°
a = c = 145°
b = 35°
d = 180 - 110 = 70°
e = d = 70°
f = 110°
g = 180 - 125 = 55°
i = g = 55°
h = 125°
j = 180 - 130 = 50°
m = j = 50°
o = k = d = e = 70° (as this line crosses 2 levels)
l = f = 110°
n = 180 - m - o = 180 - 50 - 70 = 60°
s = 180 - 23 = 157°
p = 23°
r = 68°
q = 180 - p - r = 180 - 23 - 68 = 89°
t = 180 - 68 = 112°
v = w = z = 132° (as this line crosses 2 levels)
A = 180 - 132 = 48°
y = x = u = A = 48°
B = 180 - 39 - 47 = 94°
D = B = 94°
C = 39 + 47 = 86°
E = 47°
F = B + 39 = 94 + 39 = 133°
A ball is thrown into the air from a height of 4 feet with an initial velocity of 63 ft/sec. The function that models this situation is h(t) = –16t2 + 63t + 4, where t is measured in seconds and h is the height in feet.
(a) What is the height of the ball after 2 seconds?
(b) What is the maximum height of the ball?
(c) When will the ball hit the ground?
(d) What domain makes sense for the function?
#1
h(2)-16(2)²+63(2)+4-16(4)+126+4-64+13066ft#2
Convert to Vertex form of parabola y=a(x-h)²+k
y=-16t²+63t+4We need calculator now
y=-16(t-1.969)²+66.02On comparing
Vertex=(h,k)=(1.969,66.02)As a is negative so parabola is opening downwards hence vertex is maximum
Max height=66.02ft#3
When h(t) is 0 ball hits the ground
-16t²+63t+4=0-16t²-t+64t+4=0On solving we get t=-1/16 or 4
Take it positive
t=4sAt 4s it reach the ground
#4
Domain is set of all t values (Time axis)
Here
ball starts from 0s and hits 0 again at 4s
So domain=[0,4]
Answer:
(a) 66 ft
(b) 66.015625 feet
(c) 4 s
(d) 0 ≤ t ≤ 4
Step-by-step explanation:
[tex]h(t)=-16t^2+63t+4[/tex]
Part (a)
[tex]t=2 \implies h(2)=-16(2)^2+63(2)+4=66[/tex]
Therefore, the height of the ball after 2 seconds is 66 feet
Part (b)
The maximum height will be the turning point of the parabola.
To find the turning point, differentiate the function:
[tex]\implies h'(t)=-32t+63[/tex]
Set it to zero:
[tex]\implies h'(t)=0[/tex]
[tex]\implies-32t+63=0[/tex]
Solve for t:
[tex]\implies 32t=63[/tex]
[tex]\implies t=\dfrac{63}{32}=1.96875[/tex]
Input found value of t into the function and solve for h:
[tex]\implies h(1.96875)=-16(1.96875)^2+63(1.96875)+4=66.015625[/tex]
Therefore, the maximum height of the ball is 66.015625 feet
Part (c)
The ball will hit the ground when h(t) = 0
[tex]\implies -16t^2+63t+4=0[/tex]
[tex]\implies 16t^2-63t-4=0[/tex]
[tex]\implies 16t^2+t-64t-4=0[/tex]
[tex]\implies t(16t+1)-4(16t+1)=0[/tex]
[tex]\implies (t-4)(16t+1)=0[/tex]
[tex]\implies t=4, t=-0.0625[/tex]
As time is positive, t = 4s only
Part (d)
As time is positive, and the ball hits the ground when t = 4 s, the domain should be restricted to: 0 ≤ t ≤ 4

A fruit company delivers its fruit in two types of boxes: large and small. Delivery of 8 large boxes and 4 small boxes has a total weight of 173 kilograms. Delivery of 3 large boxes and 2 small boxes has a total weight of 68 kilograms. How much does each type of box weigh?
Weight of each large Box: ?
Weight of each Small Box: ?
Answer:
x = 18.5 (large) , y = 6.25 (small)
Step-by-step explanation:
Let's start by assigning variables to each type of box.
The large box we will call "x"
The small box we will call "y"
We know that 8x + 4y = 173 (kilograms)
And 3x + 2y = 68 (kilograms)
Since we set up a system of equations, we can now use elimination, by multiplying the entire bottom equation by -2, to get rid of the "y" variable.
8x + 4y = 173
3x(-2) + 2y(-2) = 68(-2)
-6x + -4y = -136 (side note: notice how the "y"'s would cancel each other out because -4y + 4y equals 0)
Add equations together:
2x = 37
x= 18.5
Now that we have x, just substitute it into any of the equations to get y.
You will see that y = 6.25
