Answer:

A. r = -0.93

Step-by-step explanation:

First, if there is a negative correlation, the correlation coefficient will be negative.

This eliminates answer choices C and D, which are positive.

If there is a strong correlation, the correlation coefficient will be closer to 1, or -1 (since the correlation is negative).

Since -0.93 is closer than -0.23 to 1, it has a stronger correlation.

So, the correct answer is A. r = -0.93

Order the fractions from least to greatest: 2/3,5/6,29/36,8/9. Briefly explain your method.
elena-14-01-66 [18.8K]

Answer: 2/3, 29/36, 5/6, 8/9

Step-by-step explanation:

You find the common denominator you could use for all fractions. In this instance, you can use 36 for the common denominator.

2/3: 36/3=12, 2x12=24 therefore 2/3 becomes 24/36.

29/36: you leave this one alone, it has already been simplified.

5/6: 36/6=6, 6x5=30 therefore 5/6 becomes 30/36.

8/9: 36/9=4, 8x4=32 therefore 8/9 becomes 32/26.

Expand the number 1120 into its corresponding exponential form. 25 · 5 · 7 52 · 8 22 · 53 · 7 2 · 5 · 7
Eduardwww [97]

Answer:

(A) 2^{5} * 5 * 7

Step-by-step explanation:

Your question formatting made it very complicated to understand the possible answers.  Please use some notation or the equation editor next time.

So, the exponential form a way to write a number using multiplications and powers.

Let's examine the various options (if I read them correctly)

(A) 2^{5} * 5 * 7 - YES!

2^{5} is 32, so 32 * 5 * 7 = 160 * 7 = 1120

(B) 5² · 8  - NO

= 25 * 8 = 200

(C) 2² * 5³ * 7 - NO

= 4 * 125 * 7 =500 * 7 = 3500

(D) 2 · 5 · 7 - NO

= 10 * 7 = 70
