Y=9x+5 theres your answer
Answer:
This statement is false because there are waves and currents which changes because of the moon
Step-by-step explanation:
You flip 3 coins 20 times and record the number of heads. The results are listed below. 2, 1, 0, 2, 2, 0, 2, 2, 3, 2, 1, 2, 1, 2

Answer:
You would expect to get 0 heads and 3 heads about the same number of times
This would be a good experiment to use to find the probability that a family with 3 kids has 1 boy
Step-by-step explanation:
Step 1: Construct a frequency table
Number of heads Tally mark Frequency
0 II 2
1 IIIII II 7
2 IIIII III 8
3 II 2
Step 2 : Check the statements
<em>You would expect to get 0 heads and 3 heads about the same number of times</em>-True because the frequency of 0 heads is 2 and the frequency of 3 heads is also 2.
<em>You would expect to get 1 head and 2 heads about the same number of times</em>-False because the frequency of getting 1 heads is 7 whereas the frequency of getting 2 heads is 8.
<em>This would be a good experiment to use to find the probability that a family has a dog or a cat</em>-False because the experiment done above has 3 objects (3 coins) whereas this experiment has just 2 objects (cat and dog).
<em>This would be a good experiment to use to find the probability that a family with 3 kids has 1 boy</em>-True because both experiments have 3 objects and just like we found the frequency of getting 1 heads, we can find the frequency of getting 1 boy out of 3 kids.
