Answer:
y + 4 = a(x - 7)^2
Step-by-step explanation:
The standard vertex form of a parabola with vertex at (h, k) is
y - k = a(x - h)^2
and if we start with the simplest case, y = a(x)^2 and translate its graph 7 units to the right and 4 units down, we get y - {-4] = a(x - 7)^2, or
y + 4 = a(x - 7)^2
Y=mx+b
m=(325-180)/(9-4)
m=145/5
m=29
y=29x+b, using point (4,180) we can solve for b
180=29(4)+b
180=116+b
64=b, so the line is:
y=29x+64
Now the standard form of a line is ax+by=c so:
-29x+y=64 (by convention the coefficient of x should be positive so)
29x-y=-64
...
We can use the point-slope form we found earlier...
f(x)=29x+64
...
This is just a line so you can use any two points to graph it.
Connect (1,93) to (2,122) and extend upward and to the right as far as you please. The x-axis should be labeled "days" and the y-axis as "dollars".
Answer:
3/4
Step-by-step explanation:
there is no y intercept but it is 3/4 when you simplify

Subtract 9:30 - 7:15
Using it's concept, it is found that there is a 0.3043 = 30.43% probability of at least one O-ring failing.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, of the 23 flights, 7 had at least one failure, hence the probability is given by:
p = 7/23 = 0.3043.
