45 miles is how far you walked in 9 hours
Step-by-step explanation:
5 miles per hour x 9 hours = 45 miles
Answer: 0.058
Step-by-step explanation:
Number of quarters = 15
Number of dimes = 9
Number of nickels = 10
Number of pennies = 6
Total number of coins = 40
The probability of selecting a quarter first will be 15/40 = 3/8
Since it's not replaced, there'll be 39 coins left and the probability of choosing a penny is 6/39 = 2/13
Therefore, P(quarter, then penny) will be:
= 3/8 × 2/13
= 6/104
= 0.058
Factor
=(2x - 3)(2x + 5)
roots (zero)
2x - 3 = 0
2x = 3
x = 3/2
x = 1.5
2x + 5 = 0
2x = -5
x = -5/2
x = -2.5
The answer is
2.358×10^-3
