I don’t think you included the questions but there is a question similar to this on here also so i’ll share what i got for that:
you need to multiply it by 2.5. you determine it by dividing 30 by 12.
1/4 x 2.5 = 5/6
you need 5/6 ounces of yeast
1/3 x 2.5 = 5/6
you need 5/6 cups of powdered milk
6 x 2.5 = 15
you need 15 tablespoons of butter
3 1/2 x 2.5 = 8.75
you need 8.75 cups of bread flour
Answer:
Given that out of 30 planted seeds only 9 of the m sprouted, then:
Experimental probability =(number of occurrence of event)/(total number of trials made)
=9/30
=3/10
thus the number of seeds that will sprout given that 20 seeds we planted will be:
3/10×20
=6 seeds
