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
1st step you subtract 7 from both sides and the 7 get cancelled so you will get
2nd step you divide by 10 from both sides so you will get
3rd step is that you final answer is
Answer:
I think his age is 39.
Step-by-step explanation:
If Cesar's age was 2 times Rosa's 6 years ago, that means their combined ages 6 years ago was 66. 66 dived by 2 is 33 and 33 plus the 6 years is 39.
Use the given conditions to write an equation for each line in point-slope form. Passing through (2, -3) and perpendicular to the line whose equation is y = 1/5 x + 6. Question options:
y + 8 = 5(x - 6)
y - 3 = -5(x + 20)
y + 3 = -5(x - 2)
Answer:
-3/1
Step-by-step explanation:
It's always the x value over the y value, so whatever's in the x
