MachineA: y=120x
MachineA could pack in 12 min
y=120(12)
y=1440
MachineB could pack in 12 min
y=150(12)
y=1800
MachineB pack than MachineA
1800-1440
=360 candies
Answer:
D. Infinitely many solutions
Step-by-step explanation:
1.Since neither equation contains an isolated. However, we can isolate -y in the first equation by adding to both sides.
Like this:
ending up with
2.Now, we can change y to a positive y. By doing so, we divide -y by the entire equation.
Like this
Ending with
3.Now, we can plug the expression into the second equation as a substitute for y, and solve for x. Then, we can use x to calculate y.
Like this
4. Since -2x+2x would cancel out and leave -30=-30. This is true because we know -30 equals -30 with no variable in sight.
2.
M must be (0,0) since it coincides with the origin
R must be (a+b, √(a²-b²)).
The x-coordinate is b from A translated to the right by a.
The y-coordinate is the same as A.
(I think the square root is there to confuse you).
3.
R(0,0)
C(a,b) (same x as T, same Y as E)
5.
Not sure how to prove that.
Answer:
Step-by-step explanation:
We shall calculate the standard variate factor (Z factor) for each of the two given values
Thus
Similarly
Using the standard tables we get the percentage of area between is
thus 98.75% women are getting the job
b)
No too many women are not denied the opportunity of the job As 98.75% women get the job.
c)
Using the new requirements the area corresponding to the 1% shortest is
The height requirements are height should be greater than 57.78 inches and it should not be more than 68.753 inches corresponding to the tallest 2%. These values are arrived at using the standard normal distribution table values.
