The toylot company makes an electric train with a motor that it claims will draw an average of only 0.8 ampere (a) under a normal load. a sample of nine motors was tested, and it was found that the mean current was x = 1.34 a, with a sample standard deviation of s = 0.48 a. do the data indicate that the toylot claim of 0.8 a is too low?
what is the value of the sample test statistic? (round your answer to three decimal places.)find the p-value. (round your answer to four decimal places.)

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the ratio of grapes to blueberries she should use is 12: 3

step-by-step explanation:

if mandie is making 15 cups of fruit salad, the ratio of grapes to blueberries she should use is 12: 3.
