Number 8 is 36cm i dont know about the other question
Answer:
-3
Step-by-step explanation:
The general rule can be found by noticing patterns such as the numbers get smaller by 3 from the first term 3 towards the next 0 and towards next one -3
term 1: 3
term 2 : 3 -3 = 0
term 3 : 0 -3 = -3
The general rule of 3;0;-3 is subtract 3
Answer:
1) y=1/2x+12
2)y=-2x+13
3) Parallel lines have same slope, different y intercept and perpendicular lines have opposite reciprocal slopes.
Step-by-step explanation:
Answer:
The second equation does not have the same solution, or -15 = -10 + z
Step-by-step explanation:
Every other equation is = to -2, while the one shown above is -5.
Answer:
the statements given above are true.
Step-by-step explanation:
Given that Frederick designed an experiment in which he spun a spinner 20 times and recorded the results of each spin.
He spun a 4 five times.
The statements true are:
i) For the experimental outcomes to be closer to the predicted outcome, the number of trials should be increased.
iii) If the number of trials is changed, the experimental probability also changes.
iv) If the number of trials is changed, the predicted number of outcomes also changes.
v) If the number of trials is changed, the number of experimental outcomes also changes.
