Answer:
<u>1. The theoretical probability of rolling an even number and flipping heads is 25%.</u>
<u>2. The experimental probability of rolling a 1 and flipping tails is 15%.</u>
<u>3. The experimental probability of flipping heads is 40%.</u>
<u>4. I think around 7%.</u>
<u>5. I would expect to roll 3 and land on heads 8 times.</u>

Answer:
Table A
Step-by-step explanation:
looking at the two tables, we have the observations as follows;
For table B, if we divide x by y; we have a ratio of 2/3
This happens throughout the table
What this means is that x = 2/3 * y
But for table A, we notice a pattern for the first two lines
The pattern here is that x = 2y
But as we move to the next two rows, we notice this fails and thus, we fail to establish a pattern that works for all the rows;
Hence table B has a pattern for all its rows
The correct answer would be Choice B: 4 square units.
When the scale factor is 1/5, that means the lengths of the sides are 1/5 of the original size. So instead of having a base of 20 and height of 10, the new triangle has a base of 4 and a height of 2.
The area of the triangle is: (4 x 2) / 2 = 4
Answer:
1. About 1/5 chance that Mary is chosen
About 1/7 chance John is chosen
2. about 0.0286 chance mary is chosen
about 0.0154 chance john is chosen
same as answer 2
Step-by-step explanation:
1. If you do proportions, a female's chance comes to 1/5 and a male's chance comes to 1/7.
2. for females, do 1/35 and males do 1/65
same as answer 2
