Answer:
29 sq in
Step-by-step explanation:
Area of the figure = Area of square + Area of parallelogram + Area of rectangle
Answer:
Step-by-step explanation:
L'Hopital's rule says that, if both numerator and denominator diverge, then we can look at the limit of the derivates.
Here we have:
The numerator is ln(5x) and when x tends to infinity, this goes to infinity
the denominator is 5x, and when x tends to infinity, this goes to inifinity
So both numerator and denominator diverge to infinity when x tends to infinity.
Then we can use L'Hopithal's rule.
The numerator is:
f(x) = Ln(5x)
then:
f'(x) = df(x)/dx = 1/x
and the denominator is:
g(x) = 5*x
then:
g'(x) = 5
So, if we use L'Hopithal's rule we get:
Answer:
C. 3.4
Step-by-step explanation:
We need to find expected value, which is essentially the value that we expect to get based on the amount of each "thing" at hand.
Here, we have 4 multiple-choice questions worth 3 points each and 2 true/false questions worth 1 point each. Each multiple-choice question has 5 possible answers, so the probability that you get that multiple-choice question correct is 1/5. Similarly, each true/false question has 2 possible answers, so the probability that you get that question right is 1/2.
Expected value, denoted by E(x), has the formula:
E(x) = ∑ xp(x), where x is the number of points you get per problem here and p(x) is the probability of getting the problem correct
E(x) = 4 * 3 * (1/5) + 2 * 1 * (1/2) = 12/5 + 1 = 17/5 = 3.4.
The answer is thus C.
Answer:
y - 50
Step-by-step explanation:
Not sure if that's what you are looking for, but 50 less than a number is the number minus 50
