Fourteen out of 20 teens said they eat breakfast every morning what is a reasonable prediction for the number of teens out of 12
Oksi-84 [34.3K]

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
