Answer:
the number of hours worked per week
the total amount he earns each week
Step-by-step explanation:
There are 2 salary options.
1. given Jeremiah can work at rate of 9 per hour with weekly bonus $50
here
here x = the total amount he earns each week
2. given Jeremiah can work at rate of $10 with no opening bonus
here x = the number of hours worked per week
You know 1 is not a root because the sum of the coeffcients of the equation is 14, not zero.
It is fairly easy to try 3 by synthetic division (see attachment), which tells you that 3 is a root and the remaining quadratic factor is x²-3x-5. The quadratic formula tells you the roots of that factor are
... x = (-b±√(b²-4ac))/(2a) = (3±√29)/2
The appropriate choices are
... C. (3-√29)/2
... D. (3+√29)/2
... F. 3
_____
The quadratic formula tells you the solution to
... ax²+bx+c=0
is x = (-b±√(b²-4ac))/(2a)
We have a=1, b=-3, c=-5.
Simple addition my dear friend. We know that Tina is 5 years older than John. So however old John is, if you ad 5 to that, you get Tina's age. So, 10 + 5 = 15. Tina is 15 years old.
Answer:
The correct answer is A. Both samples are dependent samples.
Step-by-step explanation:
Both samples are dependent samples, since to verify the effects of one, it is necessary to compare it with the effects and characteristics of the other.
Thus, in the case, it is intended to check the effects of caffeine on taste by using a regular soda sample first, and then comparing it with a decaffeinated soda sample. Therefore, the effects of one sample will be checked and compared with the other sample, so that there is a dependency relationship between the two, since neither could prove the hypothesis on its own.
