Answer:
55%
Step-by-step explanation:
probability of something happening = p
probability of that thing not happening = 1 - P
45%= 45/100= 0.45
therefore, the probability of snow today = 0.45
therefore,
probability there will be no snow=1 - 0.45 = 0.55
probability there will be no snow= 0.55
convert 0.55 back to percentage= 0.55×100= 55%
probability there will be no snow= 55%
Answer:
{x,y} = {1/3,1/9}
Step-by-step explanation:
Solution :
{x,y} = {1/3,1/9}
System of Linear Equations entered :
[1] 4x + 6y = 2
[2] -4x + 3y = -1
Graphic Representation of the Equations :
6y + 4x = 2 3y - 4x = -1
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 3y = 4x - 1
[2] y = 4x/3 - 1/3
// Plug this in for variable y in equation [1]
[1] 4x + 6•(4x/3-1/3) = 2
[1] 12x = 4
// Solve equation [1] for the variable x
[1] 12x = 4
[1] x = 1/3
// By now we know this much :
x = 1/3
y = 4x/3-1/3
// Use the x value to solve for y
y = (4/3)(1/3)-1/3 = 1/9
Solution :
{x,y} = {1/3,1/9}
The answer there is the answer I got after figuring it out
The spread of the disease will take a time 100 days to reach 2,500 <em>infected</em> people.
<h3>How to find the number of infected people at a certain time</h3>
In this problem we have a <em>radical</em> equation that represents the number of <em>infected</em> people as a function of time, we are suppose to find the time when that number will be 2,500 by <em>algebra</em> properties: (N = 2,500)
2,500 = 250 · √t
√t = 2,500 / 250
√t = 10
t = 10²
t = 100
The spread of the disease will take a time 100 days to reach 2,500 <em>infected</em> people.
<h3>Remark </h3>
The statement is poorly formatted and presents typing mistakes, correct form is shown below:
<em>The spread of a disease can be modeled as N(t) = 250 · √t, where N is the number of infected people, and t is time (in days). How long will it take until the number of infected people reaches 2,500?</em>
