Answer:
P(heads appears on only the last toss) = 
Step-by-step explanation:
A fair coin is tossed 3 times in a row.
When a coin is tossed we get a tail or head T or H
The possible outcomes of 3 coins are
T T T , H H H , T H H, H T H, H H T, H T T , T H T, T T H
So total of 8 possible outcomes
heads appears on only the last toss , first and second toss should be tail
So its T T H. Only one possibility
Probability(any event) = number of outcomes / total outcomes
P(heads appears on only the last toss) =
Number 17 9216 because you take 96*4
Answer:
1. C. Yes, because a sum of cubes can be factored
2a. false
2b. false
2c. true
2d. false (based on what is written in the equation; refer to step-by-step)
Step-by-step explanation:
1. Both 3 and 8 can be cubed, which is why x^3+8 can be factored (x+2)(x^2-2x+4)
2a. a^2-b^2 can be factored by the perfect square rule, so it should be (a-b)^2
2b. both terms are perfect squares, so you can factor, making it (a+b)(a-b)
2c. You can factor using the perfect square rule, making it (a+b)^2
2d. Most of what is in the equation is true, yet the correct solution would be (a-b)(a^2+ab+b^2)
Answer:
- 5
Step-by-step explanation:
Substitute the given values into the expression
ax + by
= (- 2 × 1) + (3 × - 1)
= - 2 + (- 3)
= - 2 - 3
= - 5
