Hello,
1) order the terms:
3x^3+6x^2+5x+10
2) method: grouping 2 to 2 the terms:
=(3x^3+6x^2)+(5x+10)
=3x^2(x+2)+5(x+2)=(x+2)(3x^2+5)
Answer:
I think it’s the first one, A
Answer:
25%

Convert fraction (ratio) 15 / 60 Answer: 25%
In your question where ask to find the Standard Normal Distribution of the following:
give probabilities for 0<Z<infinity.
For these ranges, you can read directly, for example,
P(Z<1.96)=0.975.
So for #1, you read directly on the line 1.3 and column 0.03.
For #2, we note that the distribution is symmetrical about Z=0, so
P(Z<-2.33) is the same as P(Z>2.33)
which again is the same as
1-P(Z<2.33) because we know that the area under a probability distribution function adds up to 1.
For the remaining questions, work is similar to #2.
