Answer:
<u>The correct answer is B. 3/10.</u>
Step-by-step explanation:
1. Let's calculate the probability of spinning an odd number:
We can spin an odd number (1, 3 or 5) out of 5 events, it means that the probability of spinning an odd number is:
3/5
2. Let's calculate the probability of getting tails on the coin:
We can toss a coin and get tails one out of 2 events, it means that the probability of getting tails on the coin is:
1/2
3. These are independent events because the fact that we spin an odd number does not affect the probability of getting tails on the coin, thus:
Probability of spinning an odd number and getting tails on the coin =
3/5 * 1/2 = 3/10
<u>The correct answer is B. 3/10</u>

pls mark me brainliest
Isn't it already in standard form?
Examples :
2/x < 4 ....multiply both sides by x, cancelling it on the left side
2 < 4x ...now divide by 4
2/4 < x
1/2 < x
5/x + 7 > = 12
5/x > = 12 - 7
5/x > = 5 ....multiply by x, cancelling it on the left
5 > = 5x...divide by 5
5/5 > = x
1 > = x
Step-by-step explanation:
f(x) = x² + 2x - 4
g(x) = 3x + 1
f(g(x)) = f(3x + 1)
f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4
= 9x² + 6x + 1 + 6x + 2 - 4
= 9x² + 12x -1
