First of all, we know that Dianna has total 6+5+4=15 coins including: 6 quarters, 5 dimes and 4 nickles in her purse.
P(grabbing the first dimes):
5/15 or 1/3
P(grabbing the second dimes):
5/15 or 1/3
P(grabbing 2 dimes in a row):
1/3*1/3=1/9. As a result,the probability that Diana grabs 2 dimes is 1/9. Hope it help!
Answer:
y = 4/3x - 10
Step-by-step explanation:
Slope: 4/3
y-intercept: -2 - (4/3)(6) = -2 - 8 = -10
x/2 < -1
Solve for x by multiplying both sides by 2:
X <-2
The solution for X is any number less than -2
Four solutions can be:
-3, -4, -5, -6
Hello!
We need to find a denominator that both fractions can be. /63 works perfectly because 7x9 = 63. 3 x 9 = 27, and 4 x 7 = 28. Since 28/63 is bigger than 27/63, ramundus puts more money into car expenses.
