The coin landed on tails 6 out of 15 times.
The experimental probability of landing on tails was 6/15, which reduces to 2/5
Answer:
0.06
Step-by-step explanation:
Total number of marbles:
6 + 10 + 5 + 1 = 22 marbles
Probability of picking 1 red marble:
red marbles / total marbles
6/22
Probability of picking a green marble:
green marbles / total marbles
5/22
Now, multiply the probabilities:
6/22 • 5/22 = 15/242 = 0.06
The required scale model will be 1:6.24 10^9
<h3>Finding scale factors</h3>
A scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure.
Given the following parameters
Distance of sun to Jupiter = 7.8 * 10^8 km
If the distance of sun to Jupiter is 8m on his scale, hence the value of n is calculated as;
n = 8 * 7.8 *10^8
n = 62.4 * 1068
n = 6.24 10^9
Hence the required scale model will be 1:6.24 10^9

This problem could be set up algebraically or you could use trial and error.
a) 9 and 4 (9 + 4 = 13, 9 * 4 = 36 and 36 - 23 = 13)
I won't give you the rest of the answers, but the second and third ones have to add together to equal a negative number and multiply to equal a positive number. I hope this helps some.
