Answer:
how do you do this math ?
Step-by-step explanation:
Answer:
x = 4 or x = 3/2
Step-by-step explanation:
You want the solution to the equation 3(x - 4)(2x - 3) = 0 ?
ok then.
it looks like either x - 4 = 0
or 2x - 3 = 0
so...
x = 4 or x = 3/2
Answer:
The top 30% is defined with a score greater than or equal to 431.44 so she will not be admitted (D)
Step-by-step explanation:
Mean m = 400
Standard deviation S = 60
Firstly, we have to determine the cut off mark,
Since Only students who score in the top 30% are accepted, the cut off mark can be determined from 70% of the mark.
P(cut off mark = X) = Z[( X -m)/S) <x]
=¢(X-400/60) = 0.7
From Normal distribution table,
X-400/60 = 0.524
X = 431.44
Therefore, the cut off mark is 431.44
Since Amy scores 425 on the test.
Therefore, The top 30% is defined with a score greater than or equal to 431.44 so she will not be admitted (D)
Answer: 5x^(-1) or 5/x.
Step-by-step explanation: The equation given is (5*x^2)/x^3 and we are supposed to solve it for x = 2. First. we simplify the equation. Since we have x^2 in the numerator and x^3 in the denominator, using the equation a^x/a^y = a^(x - y) we find that we get 5*x^(-1) we can leave it like this or simplify it to 5/x, since negative exponents mean fractions.
Answer:
Rate for 100 miles = $ 6 / miles
Rate for 250 miles = $ 3.3 / miles
Step-by-step explanation:
Given that cost for covering 100 miles by flight is $600.
As rate is the cost of covering unit distance (in miles).
So, the rate to cover 100 miles by flight = $ 600/ 100 miles = $ 6 /miles.
Similarly, the cost of covering 250 miles by flight is $825.
So, the rate to cover 250 miles by flight = $ 825/ 250 miles = $ 3.3 /miles.
