Hence the answers would be

A standardized variable always has a mean of __0_____ and a standard deviation of ___1____. b. The z-score corresponding to an observed value of a variable tells you ____the std normal score.___. c.

Brad the pair of fractions as a pair of fractions with a common denominator 3/10 and 1/2

LuckyWell [14K]

Answer:

2/10 and 3/10

Step-by-step explanation:

Hello!

The best way of finding common denominators is using their factors!

(of denominators)

10 : 1, 2, 5, 10

2 : 1, 2

We also can see that 10 is divisible by 2.

For that reason, 1/2 is equivalent to 2 * 10 ÷ 2.

That's 10.

So 5/10 and 3/10 have a common denominator 10.

Hope this helps!
