A kilogram of whole- wheat flour cost $6. what is the cost of 400 grams of the flour?

1 answer:

6 0

As you know, 1kq=1000g

To simplify the problem, we should get the amount of money 200g of flour will cost.

So we do 5/6 (5=amount of parts off 200g and 6=the amount of money) which equal to $1.2/200g

1.2*2=$2.4

Hence 400g=$2.4

A sample of students will be selected from all the students at a high school. Which of the following sampling methods is least l

strojnjashka [21]

Answer:

B. Divide the students into the four class years (freshman, sophomore, junior, senior) and randomly select students from each year in proportion to the number of students in each year.

Step-by-step explanation:

The question is missing the options. The options should be:

A. From a list of all student names, randomly select 50 names from the list for the sample.

B. Divide the students into the four class years (freshman, sophomore, junior, senior) and randomly select students from each year in proportion to the number of students in each year.

C. From a randomly chosen home basketball game, choose every tenth student who enters the gymnasium.

D. Randomly choose five classrooms in the school and use all the students in those classrooms for the sample.

E. From a numbered list of all student names, randomly choose a starting point and then choose every tenth student on the list.

From reading the option, the option A and E is pretty similar. It is a simple random sampling from the list of all students. Option C is bad because you random based on the student that watch a basketball game. Option D doing random sampling but randomize classes instead of an individual student.

The best method will be option B since you randomized the number in proportion to the number of the class of the student. This randomization is called cluster sampling.

Answer:

c = 17

Step-by-step explanation:

Since this is a right angle triangle we can use the Pythagoras theorem that states that $c^{2} = a^{2} + b^{2}$ (where c is the Solve for hypotenuse and "a" and "b" are the legs of the right angle triangle). From here we know that the answer to this question is....
