The answer is no , because there is 0 twice !
Answer:
-7/5
Step-by-step explanation:
3(x + 1) + 2 (x + 2) >0
(3x + 3) + (2x + 2 * 2) >0
(3x + 3) + (2x + 4) >0
= -7/5
Answer:
between 45% and 51%
Step-by-step explanation:
Data provided:
Margin of error = plus or minus 3%
Confidence level = 95%
Number of voters asked = 1,000
Respondents considered themselves independent = 48%
Now,
adjusting the margin of error in the result
we get
the range as:
lowest value of range percentage of independents among voters in Maine
= 48% - 3%
= 45%
and,
Highest value of range percentage of independents among voters in Maine
= 48% + 3%
= 51%
Hence,
the percentage of independents among voters in Maine are between 45% and 51%
Answer:
(x+5)(x-4)(x-3)
Step-by-step explanation:
Divide (e+5) into e³-2e²-23e+60 using polynomial long division (picture attached below). Since it divides in evenly, we can see it is a factor.
So we can say e³-2e²-23e+60 = (e+5)(e²-7e+12)
To complete the factorisation, factorise e²-7e+12.
Note that (x+a)(x+b)=x²+(a+b)x+ab. So find the multiples or 12 which can be added or subtracted to get -7: -4 and -3.
e²-7e+12=(x-4)(x-3)
So e³-2e²-23e+60 = (x+5)(x-4)(x-3)
Answer:
$2.56
Step-by-step explanation:
P(7 or 11) = 8/36 = 2/9
P(winning 20-2 = 18) = 2/9
P(2 or 12) = 2/36 = 1/18
P(winning 2-2 = 0) = 1/18
P(others) = 26/36 = 13/18
P(winning 0-2 = -2) = 13/18
Expected win
= 18(2/9) + 0(1/18) - 2(13/18)
= $23/9 or $2.56
