For a specific location in a particularly rainy city, the time a new thunderstorm begins to produce rain (first drop time) is uniformly distributed throughout the day and independent of this first drop time for the surrounding days. Given that it will rain during some period on both of the next two days, what is the probability that the first drop of rain will be felt between 9:15 AM and 2:50 PM on both days
Answers
Answer:
The required probability = 0.0541
Step-by-step explanation:
From the given information:
The probability that it will rain throughout the day is uniformly distributed & independent of the surrounding days.
Assuming that (P₁) represents the probability that it will rain between 9:15 am to 2:50 pm on day 1.
The time interval is 5 hours 35 minutes long.
= 5.583333 hours long
Thus;
P₁ = 5.583333/24
P₁ = 0.2326
Assuming that (P₂) represents the probability that it will rain between 9:15 am to 2:50 pm on day 2.
P₂ = P₁ = 0.2326
Therefore, the total probability = P₂ × P₁ (independent events)
= 0.2326 × 0.2326
= 0.05410276

Find all critical points of the given plane autonomous system. (Enter your answers as a comma-separated list.) x′ = x 12 − x − 1 2 y y′ = y(20 − y − x)
Answers
Answer:
the critical points are (0,0) , (0, 20), (12, 0) , (4,16)
Step-by-step explanation:
To consider the autonomous system
[tex]x' =x (12 -x - \dfrac{1}{2})[/tex]
[tex]y' = y( 20 -y - x)[/tex]
The critical points of the above system can be derived by replacing x' = o and y' = 0.
i.e.
[tex]x' =x (12 -x - \dfrac{y}{2}) = 0[/tex]
[tex]\dfrac{x}{2} (24 -2x - y) = 0[/tex]
x = 0 or 24 - 2x - y = 0 ----- (1)
Also
[tex]y' = y( 20-y-x) = 0[/tex]
y( 20 -y - x) = 0
y = 0 or 20 - y - x = 0 ----- (2)
By solving (1) and (2);
we get x = 4 and y = 16
Suppose x = 0 from (2)
y = 20
Also;
if y = 0 from (1)
x = 12
Thus, the critical points are (0,0) , (0, 20), (12, 0) , (4,16)

Use the line tool to graph the equation on the coordinate plane.
y = 3/4x
Answers
Step-by-step explanation:
in the equation y=mx+b, m corresponds to the slope, and b corresponds to the y-intercept. Since b is 0 at this case, we will start at (0,0). From here you can graph the line with the slope. Since it is 3/4, you would move up 3 units, and to the right 4 units to end up with the point (4,3). Now you have the two points (0,0) and (4,3), so all you need to do is connect them to form the line.
Radha is trying to choose between two bike rental companies, Company A and Company B.
Company A charges a $25 initial fee and an additional $5 for each hour rented. Company B charges an initial $18 fee and an additional $6 for each hour rented.
The total cost to rent a bike from Company A can be represented by the equation y = 5h + 25, where h represents the number of hours rented and y represents the cost, in dollars.
The total cost to rent a bike from Company B can be represented by the equation y = 6h + 18.
For how many hours of rental is the amount charged by the two companies the same? What is the cost, in dollars, of renting the bike for this many hours?
Part A:The number of hours when the rental amount charged will be the same is
Part B:The cost of renting the bike for this many hours is
Answers
Answer:
Part A. After 7 hours the amount charged will be the same
Part B. The cost of renting the bike for that many hours (7) will be 60$.
Step-by-step explanation:
5h + 25 = 6h + 18
5h - 6h = 18 - 25
-h = -7
h = -7/-1
h = 7
Company A.
y = 5h + 25
y = (5*7) + 25
y = 35 + 25
y = 60
Company B.
y = 6h + 18
y = (6*7) + 18
y = 42 + 18
y = 60

A painter can paint 180 square feet per hour. He charges $0.35 per square foot. Today he paints for 3.5 hours. How much will he charge?
Answers
Answer:
i think it's 1800
Step-by-step explanation:
if it's wrong i'm so sorry :)
The price charged for 630 square feet is $220.5
If a painter can paint 180 square feet per hour, the amount he will paint in 3.5 hours will be 3.5 * 180 = 630 square feet
If the painter charges $0.35 per square foot, the price for 630 square feet will be expressed as 0.35 * 630 = $220.5
Hence the price charge for 630 square feet is $220.5

There are three customer service operators manning a helpline: Alex, Bobby, Charlie. Charlie is relatively new and takes one third as many calls as Bobby. Alex handles 6 times as many calls as Charlie.
What proportion of calls does Bobby handle?
Answers
Answer:
Bobby answers 30% of all phone calls.
Step-by-step explanation:
To determine the proportion of calls that Bobby answers in the call center, knowing that Charlie handles one third as many calls as him, and that Alex handles six times as many calls as Charlie, the following equivalence must be made:
A = 6 C (1/3B x 6 = 2B)
B = B
C = 1/3 B
2B + B + 1/3 B = 100
3 1/3 B = 100
3.33 B = 100
B = 100 / 3.33
B = 30
Therefore, Bobby answers 30% of calls, Alex answers 60% and Charlie 10%.
How many numbers between 1 and 100 (inclusive) are divisible by 4 or 9?
Answers
Answer:
There are 11 numbers divisible by 9 between 1 and 100, and 25 numbers divisible by 4 between 1 and 100.
Step-by-step explanation:
So there are 11 + 25 = 36, so 36 numbers divisible by one or the other, but this also includes every number which is divisible by both 9 and 4 twice.
So, for example, 36 and 72 is counted once as a number divisible by 9, and then again as a number divisible by 4. Count of such number which are counted twice 2
So answer is 11+25-2 =34

What is the volume, in cubic m, of a rectangular prism with a height of 4m, a width of
1om, and a length of 18m?
Answers
Answer:
72 cubic meters
Step-by-step explanation:
Again to calculate volume you have to take all three measurements given and multiply them like so: x times y times z. In this case x = 4, y = 1 and z = 18. When you multiply all of these terms you get 72 cubic meters.
The volume of the rectangular prism that has height of 4 m, length of 118 m, and width of 10 m is calculated as: 720 m³.
What is the Volume of a Rectangular Prism?Volume of any rectangular prism = length × width × height of the prism.
Given the parameters for the rectangular prism:
Height = 4 mWidth = 10 mLength = 18 mPlug in the values
Volume of the rectangular prism = 18 × 10 × 4 = 720 m³
