Answer:
Bottom left/ 3rd one
Step-by-step explanation:
The correct answer would be the 3rd one. Since they don't have numbers, it would be the bottom left one. A coin can land on heads or tails so the answer as to be splits to heads or tails which then splits into heads or tails.
Answer:
(1 -2y)(1 +2y)
Step-by-step explanation:
The difference of squares is factored as ...
... a² - b² = (a -b)(a +b) . . . . . . . . a form you should keep handy
Here, you have a=1, b=2y, so your factored form is ...
... 1 -4y² = (1 -2y)(1 +2y)
Answer:
56 different tests
Step-by-step explanation:
Given:
Number of wires available (n) = 8
Number of wires taken at a time for testing (r) = 5
In order to find the number of different tests required for every possible pairing of five wires, we need to find the combination rather than their permutation as order of wires doesn't disturb the testing.
So, finding the combination of 5 pairs of wires from a total of 8 wires is given as:

Plug in the given values and solve. This gives,

Therefore, 56 different tests are required for every possible pairing of five wires.
Using a ratio table to determine the number of miles that Ronney could bike in 6 days as <u>285 miles</u> is as follows:
<h3>Ratio Table:</h3>
Day Miles Biked
Day One 47.5
Day Two 95.0
Day Three 142.5
Day Four 190.0
Day Five 237.5
Day Six 285.0
<h3>What is a ratio table?</h3>
A ratio table is a structured list of equivalent (equal value) ratios that explain the relationship between the ratios and the numbers.
<h3>Data and Calculations:</h3>
Day Miles Biked
Day One 47.5 (190/4)
Day Two 95.0 (190/4 x 2)
Day Three 142.5 (190/4 x 3)
Day Four 190.0 (190/4 x 4)
Day Five 237.5 (190/4 x 5)
Day Six 285.0 (190/4 x 6)
Thus, in six days, Ronney biked <u>285 miles</u> based on the ratio table.

equivalent ratio's to 15:38
15 x 2 = 30
38 x 2 = 76
30:76 is equivalent to 15:38
15:38 x 3
15 x 3 = 45
38 x 3 = 114
45:114 is equivalent to 15:38
15:38 x 4
15 x 4 = 60
38 x 4 = 152
60:152 is equivalent to 15:38
