Answer:
896
Step-by-step explanation:
14 of 20 teens eats breakfast every morning.
The percentage of those who eat breakfast every morning
= 14/20 x 100%
= 0.7 x 100%
= 70%
So, 70% of 20 teens eat breakfast every morning.
The reasonable prediction for the number of teens that eats breakfast every morning from 1280 teens will be 70% of 1280.
70/100 x 1280
0.7 x 1280
896
The prediction would be 896 out of 1280 teens eats breakfast every morning
Answer: 9xy−16.3x−10.2
Step-by-step explanation:
Distribute:
=0.95x+−9+9xy+−18x+(−0.25)(−3x)+(−0.25)(4.8)
=0.95x+−9+9xy+−18x+0.75x+−1.2
Combine Like Terms:
=0.95x+−9+9xy+−18x+0.75x+−1.2
=(9xy)+(0.95x+−18x+0.75x)+(−9+−1.2)
=9xy+−16.3x+−10.2
Answer:
y=-3/16(x-8)^2+12
Step-by-step explanation:
Refer to the vertex form equation for a parabola:
y=a(x-h)^2+k where (h,k) is the vertex.
Therefore, we have y=a(x-8)^2+12 as our equation so far. If we plug in (16,0) we can find a:
0=a(16-8)^2+12
0=64a+12
-12=64a
-12/64=a
-3/16=a
Therefore, your final equation is y=-3/16(x-8)^2+12
