Answer:
A. y=1-2x
Step-by-step explanation:
if to substitute the values of 'x'=1; 2; 3; 4 into the equations, only the 'A' is correct.
Answer:
C≈75.4in
Step-by-step explanation:
C=2πr=2·π·12≈75.39822in
Answer:
Third choice is the correct one
Explanation:
No fraction can have a denominator = 0 because this would make it undefined.
Therefore, the solution would be all the real values except for those that make the denominator = 0
Let's check the terms in the denominator:
i. c-3 = 0 at c = 3
ii. c = 0
iii. c(c-3) = 0 at c = 0 or c = 3
Therefore 0 and 3 are the values that would make the denominator zero.
Based on the above, the solution is all real numbers except 0 and 3
Hope this helps :)
Answer:
a. 67600000
b. 0.0001396
c. 0.001479
Step-by-step explanation:
a. Since it is a permutation with repetition the formula is:
Where 
is the number of optionss, here you will use 
and 
, one for the numbers and the other for the letters. The exponent 
corresponds to how many times you have to choose a number (5 times) or a letter (two times because the first letter is always the same), then:
b. The probability of getting that exactly serial number is 1 divided by the total of possibilities:
C. The probability is the number of serials ending with AA divided by the total. The serial ending with AA can have any numbers then 
and 
The equation of that line is [ <em>y = -3/4 x - 2</em> ].
