Answer:
Option C
+ or - 3
Step-by-step explanation:
A quadratic equation will have equal roots if its Discriminant is equal to zero.
the discriminant in this case is
considering the equation,
a = 9, b= 8k, c=8
Replacing the variables in the original equation with their respective values, we will have:
Note: The values of k are meant to be + or -2.12 as seen from the workings
However, these are not in the options given. the closest choice to it
is + or - 3
Answer:
The principal amont was $35,000
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this problem, we have that:
We want to find P. So
The principal amont was $35,000
Using conversions between odds and probabilities, we have that:
1. A) 4:21
2. 0.952 probability that a bag of flour passes inspection.
3. C) 1:39
4. 41:59.
5. 14:11
Item 1:
16:84, which, simplifying by 4, is 4:21.
Item 2:
0.952 probability that a bag of flour passes inspection.
Item 3:
2.5:97.5, which, simplifying by 2.5, is 1:39.
Item 4:
Item 5:
56:44, which, simplifying by 4, is 14:11.
