In the question it gives you the equation n =
I assume that "t" represents time
Since it asks you for 7 hrs you plug 7 in the place of "t" :
This can also be written as:
so...
n =
Which can be converted into decimal form of:
23.33333
This means that Olivia will sell about 23 boxes in 7 hr
Hope this helped!
Solving these is quite simple; think of "a number" as a value of either n or x (depending on personal preference) then just find the operations being done based on key words;
1. Sum= addition so it is x+5
2. Decrease= subtraction so it is 11-n
3. Quotient= division so it is -9/y
4. Twice= multiply by two, minus= subtract, so it is 2n-13
Answer:
17-2x=-11 ---> 14
Step-by-step explanation:
plug in the "answers"
17-2(14)=-11
This will be a third degree polynomial since we have 3 zeros. We will FOIL them out. They are: (x-2), (x+7i), (x-7i). The product of the second and third factors gives us
. i^2 = -1, so if we simplify, we have
. Now we will multiply that with x-2 to get
. There you go!
Answer:
The t-score is t = 2.457.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 31 - 1 = 30
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 30 degrees of freedom(y-axis) and a one-tailed confidence level of . So we have T = 2.457.
The t-score is t = 2.457.
