Step-by-step explanation:
Answer:
b=-19
Step-by-step explanation:
We know that one of the solutions is x=-4/5
That is a solution to x. So if we plug in (-4/5) into the x in the equation, then it should equal 0.
5(-4/5)^2+b(4/5)+12=0
Now, just solve for b.
5(16/25)+b(4/5)+12=0
(16/5)+(4/5)b+12=0
(76/5)+(4/5)b=0
(4/5)b=-(76/5)
b=-19
It will take 4 minutes to rotate 1º because 15 divided by 15 is one (to get 1º) and 60 (1 hour) divided by 15 is 4.
Answer:
30%
Step-by-step explanation:
In this question, we are to calculate the percentage of students who are female and do not play instruments.
We can first infer this from the table;
The number of females who do not play instruments = 64
The percentage of females who do not play instruments = number of females who do not play instruments/total number of students surveyed * 100%
That will be;
64/213 * 100% = 30.04 which is approximately 30%
