Answer:
Percentage profit=40%
Step-by-step explanation:
Cost price=120 Naira
Sold price=168 Naira
Profit=Sold price- cost price
=168-120
=48 Naira
Percentage profit=profit/cost price×100
=48/120×100
=0.4×100
=40%
Percentage profit=40%
So what you do,is you add them together to get 13/10 but then you can also simplify it but you can keep the answer to 13/10
Answer:
B. 0.12
Step-by-step explanation:
To obtain this probability, you need to multiply the two probabilities.. since it's comprised of two events: one that he's in the brass section, one that he plays trombone. The probably of him playing trombone only happens if he's in the brass section.
So, you have the possibility he's in the brass section: 0.50
The possibility he's playing trombone, if he's in the brass section: 0.24
P = 0.5 * 0.24 = 0.12
Answer:
a
Step-by-step explanation:
Recall that the "point-slope" form of a linear equation may be expressed as
y = mx + b,
where m is the gradient.
If m is negative, the gradient is negative.
If m is positive, the gradient is positive.
In our case, if we consider option A,
x + 3y = -2 (rearranging)
3y = -x -2
y = (-1/3) x - (2/3)
if we compare this to the general equation at the top, we can see that
gradient, = m = (-1/3) which is negative.
hence option a has a negative gradient.
Answer:
I think it will be less than 69 because the tozal mean is 41 while of A is 69 mean the values has decreased
