Answer:

7 times during the first 15 minutes

Step-by-step explanation:

Remember that

$1\ min=60\ sec$

$15\ min=15(60)=900\ sec$

Decompose the numbers 18 and 42 in prime factors

we know that

$18=(2)(3^2)$

$42=(2)(3)(7)$

Find the least common multiple (LCM)

The LCM is

$(2)(3^2)(7)=126\ sec$

we need to find all multiples of 126 that are less than or equal 900.

$126*1=126\ sec\\126*2=252\ sec\\126*3=378\ sec\\126*4=504\ sec\\126*5=630\ sec\\126*6=756\ sec\\126*7=882\ sec$

therefore

7 times during the first 15 minutes

Simplify the following polynomial and write the answer in standard form. (-2x^3+5x^2-4x+8)-(-2x^3+2x-3)

Masja [62]

$(-2x^3+5x^2-4x+8)-(-2x^3+2x-3)\\\\=-2x^3+5x^2-4x+8-(-2x^3)-2x-(-3)\\\\=-2x^3+5x^2-4x+8+2x^3-2x+3\\\\=(-2x^3+2x^3)+5x^2+(-4x-2x)+(8+3)\\\\=5x^2-6x+11$

Assume that there are 2 trials.

vampirchik [111]

Answer: The p(success) = 0.6

Your question is a little unclear, but I believe you are asking about the probability that at least one of the trials in the experiment were successful.

If that is the case, you simply have to add the probability of 1 success with the probability of 2 successes.

That is 0.48 + 0.16 = 0.64

Rounding our answer to one decimal place gives us 0.6.
