Q2 - Expected and observed frequencies It is beleived that a 6-sided dice is biased so that:

If you roll the dice 360 times, what is the expected frequency for each score?

P(1) = 0.1 P(2) = 0.15 P(3)= 0.05 P(4) = 0.2
P(5) = 0.2 P(6) = 0.3

Score | 1 2 3 4 5 6
expect| ***6 boxes are here**
-ed |
frenqu|
-ency |

—————————

In fact the observed frequencies are as follows:

Score 1. 2. 3. 4. 5. 6
Observed. 39 59. 17. 71. 78. 96
frequency

What does this tell you?
1. the model seems reasonable
2. the model is wrong
3. you need to buy a new dice

20+ ! come and answer quick! triangle mno is reflected over the x-axis and then translated up 4 and right 3. how can the transformation be amended such that the translation can occur before the reflection and have the image remain in the same position? a translate the pre-image down 4 and right 3 and then reflect the figure over the x-axis. b translate the pre-image up 3 and right 4 and then reflect the figure over the x-axis. c translate the pre-image up 4 and left 3 and then reflect the figure over the y-axis. d translate the pre-image down 3 and right 4 and then reflect the figure over the x-axis.

Find the quotient. 50a2 – 98b2 -5a +7b
