Answer:
x = 13
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Geometry</u>
Step-by-step explanation:
<u>Step 1: Set up equation</u>
3x = x + 26
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract <em>x</em> on both sides: 2x = 26
- Divide 2 on both sides: x = 13
Answer:
1/2
Step-by-step explanation:
Total number of cards in a deck = 52
Total umber of red cards = 13 + 13 = 26
P(red card)
= 26/52
= 1/2
Answer:
The strong linear relationships are:
r = 0.95
r=-0.83
Step-by-step explanation:
When we have points whit apparent linear tents, we can fit the curve to a line and when the correlation coefficient (r) is equal to 1, we have perfect correlation and when r is equal to 0 we do not have a correlation.
Therefore r = 0.95 suggest strong linear relationships.
Now, we can use the same analysis with a negative value of r, so r = -0.83 is strong too.
I hope it helps you!
