Given that after a discount of 40% a furniture was bought for $438. The original price of the furniture will be calculated as follows:
discount=40%
new percentage price=100-40=60%
Original percentage price=100%
New buying price=$438
therefore, the original price was:
100/60×438
=$730
The original price was $730
Answer:
B.
Step-by-step explanation:
There are two 1/4's, five 1/2's, and three 3/4's.
So this means,
There will be two x's above 1/4,
Five x's above 1/2,
And three x's above 3/4,
Line plot B is the only line plot that matches this.
Therefore option B is the answer.
Answer: -2.10
Step-by-step explanation:
Given : 
Sample size : n= 50, since the sample size is greater than 30 , so we apply z-test.
Sample mean : 
Standard deviation : 
The test statistic for population mean :-
i.e. 
Hence, the value of the test statistic = -2.10
Answer:
the two expressions are equivalent.
Step-by-step explanation:
We know that f(x)= 3x-7 and g(x)= -2x+5, therefore:
f(x) - (-g(x)) = 3x-7 - ( +2x-5) = 3x - 7 - 2x + 5 = x -2
f(x) + g(x) = 3x-7 -2x + 5 = x - 2
Therefore, f(x) - (-g(x)) is equivalent to f(x) + g(x).
Another way to check that the two expressions are equivalent is by solving the parenthesis:
f(x) - (-g(x)) → f(x) + g(x)
Therefore, the two expressions are equivalent.
