Answer:
450,000 codes
Step-by-step explanation:
Number of digits in the access code = 6
Conditions:
- First digit cannot be 2
- Last digit must be odd
Since, there are 10 digits in total from 0 to 9 and first digit cannot be 2, there are 9 ways to fill the place of first digit.
Last digit must be odd. As there are 5 odd digits from 0 to 9, there are 5 ways to fill the last digit.
The central 4 digits can be filled by any of the 10 numbers. So, each of them can be filled in 10 ways.
According to the fundamental rule of counting, the total possible codes would be the product of all the possibilities of individual digits.
Therefore,
Number of possible codes = 9 x 10 x 10 x 10 x 10 x 5 = 450,000 codes
Hence, 450,000 different codes are possible for the lock box
Answer:
54.72
Step-by-step explanation:
- multiply 19% by 0.01
- multiply 0.19 by 288
19·0.01=0.19
0.19·288=54.72
Therefore, 19% of 288 will be 54.72.
Answer:
The zeros are x=0,3,-2
There is a multiplicity of 1 for all of them.

Answer:
B 3x+2
Step-by-step explanation:
perimiter=2L+2W
P=2(L+W)
if x=width then
P=2(L+x)
P=8x+8
hmm
8x+8=2(L+x)
distribute
8x+8=2L+2x
minus 2x both sides
6x+8=2L
divide both sides by 2
3x+4=L
the length is 3x+4
B is answer
Answer:
total population after a year ≅ 452525
Step-by-step explanation:
Population of wild turkey after a year = 1.4 x 121212 = 169696.8
Population of white-tail deer after a year = 181818 + 101010 = 282828
Hence total population after a year = 169696.8 + 282828 = 452524.8 ≅ 452525
