Henrietta surveyed her high school classmates on their favorite subjects. she recorded their gender and favorite subject. she concluded that if she surveyed 500 male and 500 female high school students she would find a higher number of males that preferred history than the number of females that preferred math. was she correct? | male | female english | 4 | 5 history | 7 | 3 math | 10 | 6 science| 8 | 10

No, she was not  correct.

There are less number of males that preferred history(121) than the number of females that preferred math(125)

We are given a table of values as:

Subjects    | Male     |    Female

English      |    4        |      5

History      |    7         |      3

Math          |   10        |      6

Science     |    8         |     10

Total          |   29        |     24

Hence, the probability of male who prefer history is: 7/29

Hence, the number of male who prefer history is:

(7/29)×500=120.6897

which is approx 121.

and the probability of female who prefer math are: 6/24

Hence, the number of female who prefer math is:

(6/24)×500=125

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

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:
