2(5.9) is 11.8
Hopefully i is right I did this in my head.
only the first statement is true - it is the experimental probability. the rest is incorrect: the ratio is not the number of trials; the theoretical probability should be 0.5 (for unbiased coins); ratio never represents a number of occurences.
Answer:
Step-by-step explanation:
The polynomial is simplified by combining like terms. Like terms are identified more easily if the variables in each term are written in the same order. We usually like to use alphabetical order. Two of the like terms have opposite coefficients, so they cancel. The result is ...
(3 1/2 -2 1/2)xy² +(-2 4/5 +2 4/5)x²y
= xy² . . . . simplified expression
__
For x = 1, y = -2, the value of the expression is ...
(1)(-2)² = 4
Answer:
B.
Step-by-step explanation:
it is obvious, 1/2x is the same as 2. Since your slope is positive, and the format is correct, B would be the answer.
<span>Round 0.30 each (or $1.80 for all 6 of them), the milk is
$1.30. Total of estimates is $11.10
The customer gave you 5 + 6 + 0.25 or $11.25, which is very close
(and slightly higher) than the total of your estimates. I'd guess the
register is correct.
Actual value is $8.04 + 6*0.29 + 1.31 = 8.04 + 1.74 + 1.31 = $11.09. The register is definitely correct. </span>
