Answer:
We conclude that a researcher used simple random sample.
Step-by-step explanation:
We know that select a sample of five children from a class of 30, a researcher puts each child’s name on a slip of paper, then shuffles the papers in a hat and randomly picks five names.
We conclude that a researcher used simple random sample.
Because every children has an equal chance of being included in the sample.
15 degrees lower than 7 degrees means that we have to subtract.
So we have 7 degrees and it wants 15 degrees lower, so we would do 7 - 15
And so 7-15 = -8
So 15 degrees lower than 7 degrees would be -8 degrees. :)
You should go up 3.5 on the Y-Axis and then go up .5 and over 1.
Less than or equal to 121 adult tickets.
You would do 1180.10/9.70
Which equals 121
Since we don't know how many children tickets were, sold it could be less than or equal to 121.
