If you spin the dial two times there three things that can happen:
1) Dial does not land in the region A
2) Dial lands once in the region A
3) Dial lands twice in the region A
The combined probability of these three events has to be 1. 
Let's calculate probabilities of each event:
1) P=P(1,1)=\frac{2}{3}\cdot\frac{2}{3}=\frac{4}{9}\\
2)P=P(1,2)+P(2,1)=2\cdot \frac{2}{3}\cdot \frac{1}{3}=\frac{4}{9}\\
3)P=P(3,3)=\frac{1}{3}\cdot\frac{1}{3}=\frac{1}{9}
If we summ all those probabilities we get 1. 
The answer would table C (lower left corner).

Someone please help me on both the questions!!!
bonufazy [111]

Step-by-step explanation:

al nth term:

numerator:

=  {n}^{2}

denominator:

= n + 1

so nth term :

=  \frac{ {n}^{2} }{n + 1}

b). 1; 11; 27; 49

first difference: 10; 16; 22

second difference :6

formula for 1st difference:3a+b

formula for 2nd difference:2a

Therefore:

2a=6

a=3

3a+b=10

sub in a

3(3)+b=10

9+b=10

b=1

sub into quadratic formula

{an}^{2}  + bn  + c

(3) {(1)}^{2}  + (1)(1) + c = 1

3(1) + 1 + c = 1

3 + 1 + c = 1

4 + c = 1

c  = - 3

So Tn:

3 {n }^{2}  +  1n - 3

9 is 3% of what number? Which proportion matches this information?
dimulka [17.4K]

Answer:

B

Step-by-step explanation:

3% = 3/100

So we can eliminate the first answer.

The proportions have to match each other so the number nine should be above and thus the x has only the option of being under it.

As a result, we eliminate the third answer and remain with one reasonable answer

Write a phrase as an algebraic expression six less than a number times 11
nadezda [96]

Let the number = x

11x is 11 times the number.  You are to take 6 less than this. Be careful how you read six less. It means the 6 is subtracted from the 11x

11x - 6 This is what you finally get.
