Furstly, multiplying mixed fractions together is chaotic. Convert them into improper fractions first.

(22/3) * (20/3) * (27/10)

Secondly, don't start multiplying all out! Look for common factors. There are two 3's at the denominator, and 27 is 3^3 at the numerator. Cross them out!

22 * 20 * 3 / 10

Hey! There are multiples of 10 too!

22 * 2 * 3

= (11 * 2) * 2 * 3

= 11 * 12

= 132

That leads to option 3!

Answer:

An ANOVA test

Step-by-step explanation:

You will use the ANOVA test, which is a test that compares the means of more than 2 samples. Since the teacher used 3 test groups, she would have to use this test if she wanted to do a hypothesis test to determine if the means are equal.

*This test only tells us if the means are equal, it won't say which is greater than the other. You would have to do 3 individual hypothesis tests comparing 2 means at a time in order to determine that.

If anything is in parentheses do that first, however if there isn’t you always do exponents next so evaluate 6 squared

At the beginning of a basketball season, the panthers won 20 games out of 50 games. At this rate, how many games will they win i

Anton [14]

Answer:

They will win 48 games in a 120 game season.

Step-by-step explanation:

The team won 20 games out of 50; that is a 20:50 ratio, that is equal to x:120. x is the amount of games won in the 120 game season.

Set up the ratios like this:

$\frac{20}{50}$ = $\frac{x}{120}$

cross multiply the numerators and denominators to get this:

20*120 = 50x

solve for x:

2,400 = 50x

x = 48

Answer:

The second option (see attached image)

Step-by-step explanation:

You are looking for a box diagram that represents 9 units, and from those, clearly marked sections that contain 3/2 = 1.5 units.The idea is to count how many 1.5 units you have in 9 units.

The in the second diagram you see 9 boxes subdivided in half. Then outlined in red other smaller boxes of length 1.5 units. We can clearly see from the diagram that there are exactly 6 of these smaller 1.5 units red boxes to produce the total 9 unit object.
