Answer:
4⋅(a⋅2)
2⋅(4⋅a)
8a
Step-by-step explanation:
(4⋅a)⋅2
4⋅(a⋅2) This is the same by the associative property of multiplication
2⋅(4⋅a) This is the same by the associative property of multiplication and the communicative property of multiplication
4⋅2⋅a⋅2 This brings in an extra 2 so it is not the same.
8a 4*2 = 8 so this is the same
4⋅2+a⋅2 This is the not the same 8+2a is not the same as 8a
M = miles Marcos drove
c = miles Candice drove
m = 2c
m + c = 66
Plug m=2c into the second equation :
m + c = 66
(2c) + c = 66
3c = 66
Choice A
Answer:
Test statistic = 2.8965
Step-by-step explanation:
The test statistic is given by the formula
z = (x - μ)/σₓ
μ = mean = 0.799
x = proportion of literate people in Tamil Nadu = (983/1185) = 0.8295
σₓ = standard error of this calculated proportion = √[p(1-p)/n]
= √(0.8295 × 0.1705/1185) = 0.01093
z = (x - μ)/σₓ
z = (0.8295 - 0.799)/0.01093 = 2.8965
z = 2.8965

Answer:
A) The indicated values of F(x) for x=-3 and x=5 are 
and 
B) The domain of f is the set of all real numbers
Step-by-step explanation:
Given that the function F is defined by
for x=-3,5
A) To find F(x) for the indicated values of x :
Given for x=-3,5
- Put x=-3 in the given function
Therefore
- Put x=5 in the given function
Therefore
The indicated values of F(x) for x=-3 and x=5 are and
B) To find the domain of f :
The domain of the f in the given expression is the set of all real numbers except where the expression 
is undefined. In this case, there is no real number that makes the expression undefined.
The domain of f is the set of all real numbers
