Answer:
99
Step-by-step explanation:
102-2=100
100-1=99
or
102-3=99
Answer:
three consecutive odd integers: 2n-1 2n+1 2n+3
that the sum of the smaller two is three
times larger increased by seven: 2n-1 + 2n+1 = 3(2n+3) +7
4n = 6n+ 9 +7
4n = 6n+ 16
4n -6n = 16
-2n = 16
n = 16/(-2)
n=-8
a) 2n -1 = 2(-8) -1 = -17
b) 2n+1 = 2(-8)+1 = -15
c) 2n+1 = 2(-8)+3 = -13
Ans. -17 ; -15 ; -13
step One
Find the total number of rocks in the gravel pit
<em>58 + 213 + 522 = 793</em>
Step Two
<em>Set up the probabilities.</em>
<em>P(Sedimentary) = 58 / 793 = 0.0731</em>
<em>P(metamorphic) = 213/ 793 =0.2686</em>
<em>P(igneous) = 522 / 793 = 0.6583</em>
Check
<em>When these are added together the answer should be one.</em>
<em>0.0731 + 0.2686 + 0.6583 = 1 just as it should.</em>
