**Answer:**

1/2 or 0.5 in decimal

**Step-by-step explanation:**

you would want to make the 3/10 eqale to 20/100 like it has to have the same denominatior which is 10x10 and 3x10. because 10x10 eqal to 100, and what you do to the bottom you have to do the same on the top. and then you add which becomes 30/100+20/100=50/100 and 50/100 =1/2 if you simplfiy.

**Answer:**

B. probability = 0.707

**Step-by-step explanation:**

Find the probability of finding 39 to 51 inclusively student with jobs from a sample of 300, given probability is 0.15.

To do so, we need to use the binomial distribution, which can be calculated with the specified calculator, or using R, available online.

The probability can be found by finding the cumulative probability, from a sample of 300 students

P( <= 51 students with jobs) = binomcdf(300,0.15,51) = 0.8530691

P( <= 38 students with jobs) = binomcdf(300,0.15,51) = 0.1460201

Therefore probability of 39 - 51 students with jobs

= P( <= 51 students with jobs)** - **P( <= 38 students with jobs)

= 0.8530691 - 0.1460201

= **0.707**0491

Divide 75 by 65 which equals 1.15

**Answer:**

7-13= -6

**Step-by-step explanation:**

(I did as much as I could with not knowing what a trinomial is)

A terminating decimal ends a so 2/3 or 0.666666.. is not terminating, it's repeating, another repeating is 0.345345345345345... (a non-repeating, non-terminating decimal would be pi)

a repeeting decimal like 0.666... would also be represented with a vinculum over the 6 (vinculum signifies a repeating group so 0.345345345 would have a vinculum over the 345 group then stop)

so termination decimals do not have vinculums or ...'s so the second choice (832.15902) is crossed out and all of the other choices are correct
