Answer:
14.4444 miles
Step-by-step explanation:
y=4+0.9x
plug in 17.5 for y
then solve
1.
a.) 2q + 5r
2(7) + 5(-2)
14 - 10 = 4
b.) 3(p + 6) + q + r Plug in the numbers
3(5 + 6) + 7 - 2 Solve inside the parentheses first
3(11) + 7 - 2
33 + 5 = 38
2.
a.) m(3m + 4n)
2(3(2) + 4(3))
2(6 + 12)
2(18) = 36
b.) n²(m + p²)
(3)²(2 + (-5)²)
9(2 + 25)
9(27) = 243
c.) 3m(8 + n) + n²
3(2) (8 + 3) + 3²
6(11) + 9
66 + 9 = 75
Answer:
742,380952381 <em>OR</em> 31180/42
Step-by-step explanation:
16/42=0,380952381
742+0,380952381=742,380952381
<em>or</em>
(742*42)/42 + 16/42 = (31164+16) /42 = 31180/42
The tickets aren't replaced, so multiply the probabilities, decreasing the denominator each time.
a) 1/48
b) (1/48)(1/47)
c) (1/48)(1/47)(1/46)(1/45)(1/44)(1/43)
