Number of times;

The mistake in Kevin's calculation is when calculating P(Red or Green).

He considered only one section instead of both sections
<u>The correction is:</u>
<em />
<em>Since, there are 2 green sections and 2 red sections.</em>
The equation becomes


And the number of times is:



Nothing can be said about the percent yield without knowing how much of at least one reactant was present before the reaction occurred.

Explanation:
I'm assuming letters can repeat.
There are 26 letters in the English alphabet.
There are,
- A = 26^4 = 456,976 strings of length four
- B = 26^3 = 17,576 strings of length three
- C = 26^2 = 676 strings of length two
- D = 26 strings of length one
Overall, there are A+B+C+D = 456,976+17,576+676+26 = 475,254 strings of length four or less.
Answer:
x = 10
Step-by-step explanation:
∆RSE ~ ∆FGE
SE/ GE = RE/ FE
45/ 12x-3 = 55/ 143
3/ 3(4x - 1) = 11/ 143
11(4x-1) = 429
44x-11 = 429
44x = 440
x =10
Answer:
A. m =
Step-by-step explanation:
<em><u>The variables "ma" are connected, implying they are together through multiplication. To remove "a" from "m," you must do the opposite, which is division. So, divide both sides by "a," like so:</u></em>
F = ma

= m
