In a recent year, a hospital had 4588 births. Find the mean number of births per day, then use that result and the Poisson distribution to find the probability that in a day there are 16 births.
Answer:
4221 birhs
Step-by-step explanation:
. Find the mean number of births per day, then use that result to find the probability that in a day, there are 15 births.
Solve the quadratic equation by using either a numeric or a graphic approach. x squared minus 16 x minus 64 = 0 a. x = -11.1 or x = -12.4 c. x = 16.3 or x = -2.9 b. x = 19.3 or x = -3.3 d. x = 1.3 or x = -3.4
Answer:
B.
Step-by-step explanation:
\(x^2 - 16x - 64 = 0\)
\((x-8)^2 = 128\)
\(x = 8 + \sqrt{128}\)
or
\(x=8-\sqrt{128}\)
so x = 19.3
or x = 3.3

hw to solve 6x-12/3+4=18/x
The two solutions of the equation:
(6x - 12)/3 + 4 = 18/x
Are x = 3 and x = -3
How to solve the equation?Here we have the following equation:
(6x - 12)/3 + 4 = 18/x
Notice that in the right side we have x on a denominator, then x can not be zero, so x ≠ 0.
Now, let's start by simplifying the left side:
(6x - 12)/3+ 4 = 18/x
2x - 4 + 4 = 18/x
2x = 18/x
Now we can multiply both sides by x so we get:
2x^2 = 18
Now divide both sides by 2:
x^2 = 18/2
x^2 = 9
Finally, apply the square root in both sides:
√x^2 = ±√9
x = ±3
The two solutions are x = 3 and x = -3

A block pulled to the left with 15 N and to the right with 5 N at the same time experiences a net force of
A. 20 N.
B. [10 N.]
C. 15 N.
D. 5 N
Answer:
A. 20 N.
Step-by-step explanation:
The net force acting on an object is the sum of all the individual forces acting on it. In this case, the block is being pulled to the left with a force of 15 N and to the right with a force of 5 N at the same time.
The net force acting on the block is the sum of these two forces, which is 15 N + 5 N = 20 N.
Therefore, the correct answer is (A) 20 N.

What is the range of function g if g(x)=-2f(x)+1
The range of g is bounded between 1 - 2M and 1, but it may not include all values in that interval, depending on the range of f.
The range of function g depends on the range of the function f.
Let's start by assuming that we know the range of f.
If the range of f is Rf, then the range of -2f is the set {-2y | y ∈ Rf}, which is just the set of all numbers that can be obtained by multiplying an element of Rf by -2.
Finally, we add 1 to each of these values to get the range of g. Therefore, the range of g is:
Rg = {1 - 2y | y ∈ Rf}
In other words, the range of g is obtained by taking the range of f, multiplying each element by -2, and adding 1 to each result.
If we don't know the range of f, we can still say something about the range of g. Specifically, we know that g(x) can never be greater than 1 (since the largest value that -2f(x) can take is 0, and adding 1 to 0 gives us 1), and g(x) can never be less than 1 - 2M, where M is the largest possible value that f(x) can take on. In other words, the range of g is bounded between 1 - 2M and 1, but it may not include all values in that interval, depending on the range of f.

At the local bookstore, 4 pape back books cost 20$. The table below represents the amount of books compared to the cost.
The relationship between the two variables can be determined as the slope, which is;
\(\begin{gathered} m=\frac{y2-y1}{x2-x1} \\ \text{Where;} \\ x1=3,x2=4,y1=15,y2=20 \\ m=\frac{20-15}{4-3} \\ m=\frac{5}{1} \\ m=5 \end{gathered}\)This means for every ordered pair in the table, the books multiplied by 5 gives the cost.
Therefore the ordered pair that would be included in the table is (10, 50) which is option number 4.

(A) = 2400 - kps
(B) = k (2400 – P)
(C) = k 1/p (2400 – P)
(D) = XP (2400 - P)
The differential equation that best models the growth rate of the rabbit population with respect to time t, where k is a constant is option D) \(\frac{dP}{dT}=KP(2400-P)\).
A differential equation is an equation that relates a function and its derivatives to some independent variables. The solution to a differential equation is a function that satisfies the equation and is often used to model physical processes.
Differential equations come in many forms, including ordinary differential equations (ODEs) and partial differential equations (PDEs).
For the population in function of the time, is:
\(\frac{dP}{dT}\)
The population P of rabbits on a small island grows at a rate that is jointly proportional to the size of the rabbit population and the difference between the rabbit population and the carrying capacity of the population
Carrying capacity is 2400.
This means that the differential equation is kP(size of the population multiplied by the constant) multiplied by 2400 - P(difference between the population and the carrying capacity).
=> \(\frac{dP}{dT}=KP(2400-P)\)
Therefore, The differential equation that best models the growth rate of the rabbit population with respect to time t, where k is a constant is option D) \(\frac{dP}{dT}=KP(2400-P)\).

Hayden has three number cards. The
minimum of his three cards is 36, the
range is 41 and the median is 46.
What is the mean of Hayden's three
cards?
Answer:
Mean = 53.
Step-by-step explanation:
The median is the middle value so the 3 cards are
36, 46, x where x is to be found.
The range is 41, so:
x - 36 = 41
x = 41 + 36
x = 77.
Therefore, the mean is
(36+46+77) / 3
= 159/3
= 53.

58. 37. 45, 52, 81, 75, 78, 72, 68, 59,

The mean age of the subjects who like the new health drink is (type your answer...)
and the median age of the subjects is (type your answer..)
Answer:
Mean = 59.1, Median = 61
(there might have been a mistake in calculation (a lot of numbers!))
Step-by-step explanation:
The sample size is 40,
Now, the formula for the mean is,
Mean = (sum of the sample values)/(sample size)
so we get,
\(Mean = (49+63+78+22+41+39+75+61+63+65+58+37+45+52+81+75+78+72+68+59+72+85+63+61+75+39+41+48+59+55+61+25+61+52+58+71+75+82+49+51)/40\\Mean = 2364/40\\Mean = 59.1\)
To find the median, we have to sort the list in ascending (or descending)order,
we get the list,
22,25,37,39,39,41,41,45,48,49,
49,51,52, 52,55,58, 58, 59, 59, 61,
61, 61, 61, 63, 63, 63, 65, 68, 71, 72,
72, 75, 75, 75, 75, 78, 78, 81, 82, 85
Now, we have to find the median,
since there are 40 values, we divide by 2 to get, 40/2 = 20
now, to find the median, we takethe average of the values above and below this value,
\(Median = ((n/2+1)th \ value + (n/2)th \ value )/2\\where, \ the\ (n/2)th \ value \ is,\\n/2 = (total \ number \ of \ samples) /2\\n/2=40/2\\(n/2)th = 20\\Hence\ the (n/2)th \ value \ is \ the \ 20th \ value\)
And the (n+1)th value is the 21st value
Now,
The ((n/2)+1)th value is 61 and the nth value is 61, so the median is,
Median = (61+61)/2
Median = 61
