Since:
ax(2x + y - 5) = 6x^2 +3xy - 15x,
we should factor X out of the second equation to find out the value of a:
6x^2 + 3xy - 15x =
x(6x + 3y - 15),
Now that we factored X out, to find a, we need to find the other common factor:
(6x + 3y - 15) / (2x + y - 5),
which is 3.
Hence the value of a is 3
Factorize
(3n + 8) (3n - 8) = 0
3n + 8 = 0 and 3n - 8 = 0
Solve both for n
3n + 8 = 0
3n = -8
n = -8/3
3n - 8 = 0
3n = 8
n = 8/3
Therefore n = -8/3 and n = 8/3
Answer:
Option 4: 0.554
Step-by-step explanation:
As we can see that the intervals and their frequencies are given.
We have to calculate the probability of students' score falling between 70 and 89. It will use the frequency of both intervals 70-79 and 80-89.
So, combined scores of both intervals are:
172+105 = 277
Now to find the probability
= 277/500
=0.554
So option no 4 is the correct answer ..
Answer:
68.7%
Step-by-step explanation:
If the cost of 819.73 for full cover insurance for a female and a male is 1192.64 what is the percentage?
The Percentage is calculated as:
819.73/1192.64 × 100
= 0.68732392004293 × 100
= 68.732392004 %
Approximately = 68.7%
Therefore, the percentage is 68.7%
