Answer:
0.21 or 21/100
Step-by-step explanation:
the chance of a female student getting a scholarship is 7/10. now that student already has a scholarship so now there are 9 students. the probability of the next female getting a scholarship is 6/9. and then the next is 5/8
7/10 x 6/9 x 5/8 = 21/100 or 0.21
Albert is walking twice ( 8/4) as fast as Kimbelry so Kimberley's speed is 1.5 yards per second.
So when Albert catches up he walks 6 + x yards while Kimberley has walked x yards.
x = 1.5t and 3t = 60 + x
3t = 60 + 1.5t
1.5t = 60
t = 60/1.5 = 40 seconds (answer)
So the time to walk 60 yards
Step-by-step explanation:
y = -4(x+6)(x-8)
= -4[x²-2x-48]
= -4x²+8x+192
Answer:
What table and, whats the question?
Step-by-step explanation:
Answer:
.
Step-by-step explanation:
The direct variation is defined as
where, k is constant of proportionality.
It is given that a direct variation function contains the points (-8,-6) and (12, 9).
Substitute x=-8 and y=-6 in the above equation.
Divide both sides by -8.
The value of constant of proportionality is 
. So, the required equation is
At x=12,
It means, the line passing through (12,9). Hence, the equation is correct.
Therefore, the equation of the function is .
