Answer:
y = 4
Step-by-step explanation:
Assuming you require the equation of the line.
A line with a slope of zero is a horizontal line parallel to the x- axis, with equation
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (7, 4 ) with y- coordinate 4, thus
y = 4 ← equation of line
Answer:
78% probability it contains no defects
Step-by-step explanation:
We have that:
10% have defects in shafts only.
8% have defects in bushings only.
4% have the two types of defects.
An assembly is selected arandom, what is the probability it contains no defects
Either it has at least one defect, or it has no defects. The sum of these probabilities is 100%. So
D + ND = 100
Probability that it has a defect
D = 10 + 8 +4 = 22%
No defects:
22 + ND = 100
ND = 78
78% probability it contains no defects
Answer:
1000 represents the amount of trash that was originally present in the landfill before dumping any extra trash.
i.e : It is the amount of trash at day zero
Explanation:
The initial value of a function is defined as the started value of the function independent of any variables present in the function
The given function is:
n = 2000x + 1000
where n is the amount of trash and x is the number of days
To get the initial value, we will set the variable (x) to be equal to zero
Therefore, initially:
n = 2000(0) + 1000 = 1000
This means that the initial value of the trash at day zero is 1000.
Hope this helps :)
Since it's so nicely grouped, we can work with it! For the equation to equal 0, x=0, 3, or -1 (since x-3 and x+1 equal 0 when plugged in with 3 and -1 respectively). All we have to do is plug in numbers before, between, and after these numbers and apply it to the rest of them. Since -1 is the smallest number of the group, we can plug in a number below that (for this example, -5) and plug it in to get -8*-5*-4= something negative since it contains an odd number of negative numbers. Therefore, anything less than 1 is negative. For between -1 and 0, we get x=-0.5 equals -0.5*-3.5*0.5=something positive (since it has an even amount of negative numbers), proving that everything between -1 and 0 here is positive. For something between 0 and 3, we can plug 1 in to get 1*-2*2= something negative. Do you see a pattern here? It's negative, then positive, etc.. Therefore, if the number is greater than 3 it is positive. Reviewing a bit, we can see that (-inf, -1) is negative as well as (0,3), making the interval notation (-inf, -1) U (0, 3) since when you plug -1, 0, and 3 in it is 0, not less than 0!
