6x-3y=3
-2x+6y=14.
First step is multiply the top equation by 2, so you have
12x-6y=6
-2x+6y=14
-6y and +6y cancel each other out, so if you simplify, you have
10x=20, which is then solved by dividing each side by 10, and getting x=2.
Now plug x=2 into one of the equations (I chose the first)
6(2)-3y=3
12-3y=3
-3y=-9, divide each side by -3 and get y=3.
so your point is (2,3)
The answer would be m ≥ 1 or m ≤ 1/3
The probability is 0.0334.
We will first find the probability that none of the 30 people sampled are infected. Since the probability of one person being infected is 0.00114, the probability that someone is not infected is 1-0.00114 = 0.99886. The probability that none of the 30 people are infected would be (0.99886)^30 = 0.966359. We subtract this from one to find the probability that at least one person is infected:
1 - 0.966359 = 0.0334.
Answer:
she can't finish reading the book in 10 days
Step-by-step explanation:
Given that:
Number of pages = 325
Number of pages read per day= 25
Using the linear relation:
y = mx + c
y = number of pages left
m = reading rate ; c = initial number of pages
y = - 25x + 325
Point slope relation :
y - y1 = m(x - x1)
m = slope
We can factorise the equation to the point slope form:
y - 325 = 25(0 - 10)
y - 325 = 0 - 250
y - 325 = - 250
y = - 250 + 325
y = 75
Hence, number of pages left after 10 days = 75, thus she can't finish reading the book in 10 days
B.)greater than five but less than six
