First find the difference in prices...
475 - 275 = 200 so the price went down 200 dollars. No we need to find what percentage of 475 is 200.
475 × x = 200
x = 200/475
x = .4211
Now convert to percentage by multiplying by 100 (move decimal 2 places to the right)
.4211 = 42.11%
It is a 42.11% price reduction.
Answer:
2x + 12 = 64
x = 26 (mark brain if this helps and is correct)
Step-by-step explanation:
to solve equations with one missing variable we must use the order of operations of equality
step 1: use the subtraction property of equality meaning subtract each side of the equation
ex: 2x + 12 - 12 = 64 - 12 (2x = 52)
step 2: use the division property of equality meaning divide each side of the equation by 2
ex: 2x/2 = 52/2 (x = 26)
step 3: check your answer by putting 26 as x because that is our answer
2(26) + 12 = 64 (multiply 2 * 26)
52 + 12 = 64 (add 52 + 12)
64 = 64 (if both sides of the equation are the same number like 64 = 64 then your answer is true meaning that x is equal to 26)
Considering the given probabilities, it is found that the correct option about whether the events are independent is given as follows:
p(x) · p(y) = p(x and y). They are independent because p(x) p(y) = p(x and y).
<h3>What are independent events?</h3>
Two events, A and B are independent, if:
Researching this problem on the internet, the probabilities are given as follows:
Hence:
Hence the events are independent and the correct option is given by:
p(x) · p(y) = p(x and y). They are independent because p(x) p(y) = p(x and y).

The square root of 78 is an irrational number, so the exact number
can't be written down, no matter how long you make the decimal.
If I say it's 8.8318, then my answer is too big, but only by about 0.0004 percent.
