What is the simplified form of the quantity 4 x squared minus 25 over the quantity 2x minus 5 ?
Alenkasestr [34]

Answer:

  B.  2x + 5, with the restriction x ≠ five over 2

Step-by-step explanation:

The given expression is the difference of squares, so factors as ...

  the product of the quantity 2x plus 5 and the quantity 2x minus 5 over the quantity 2x minus 5

You will note that the numerator and denominator have a common factor:

  the quantity 2x minus 5

Factoring that out gives ...

  2x + 5, with the restriction x ≠ five over 2 (x is restricted from being a value that makes the denominator zero.)

<em>Comment on the form of the answer</em>

Since you have written your math expressions using words instead of symbols, we assume you can read them more easily that way. So, we have provided the explanation in the form you can most easily understand. (Personally, I prefer math symbols. They are more compact and tend to be less ambiguous.)

Investing is a game of chance. Suppose there is a 36% chance that a risky stock investment will end up in a total loss of your i
Sergio039 [100]

Answer: P(x ≥ 1) = 0.893

Step-by-step explanation:

We would assume a binomial distribution for the outcome of the investment. The formula is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = (1 - r) represents the probability of failure.

n represents the number of trials or sample.

From the information given,

p = 36% = 36/100 = 0.36

q = 1 - p = 1 - 0.36

q = 0.64

n = 5

Therefore,

P(x ≥ 1) = 1 - P(x = 0)

P(x = 0) = 5C0 × 0.36^0 × 0.64^(5 - 0)

P(x = 0) = 1 × 1 × 0.107

P(x = 0) = 0.107

P(x ≥ 1) = 1 - 0.107 = 0.893
