apllo traveld 48 leauges in 3 day then he tripled his rate how long would it take him to travel 336 leagues at this new speed
Answers
48 leagues / 3 days = 16 leagues per day
Next, we know that Apollo tripled his rate, which means his new speed is:
16 leagues per day x 3 = 48 leagues per day
To find out how long it will take him to travel 336 leagues at this new speed, we can use the formula:
time = distance / speed
In this case, the distance is 336 leagues, and the speed is 48 leagues per day. So we have:
time = 336 leagues / 48 leagues per day = 7 days
Therefore, it would take Apollo 7 days to travel 336 leagues at his new speed.

A realtor sells houses in three different neighborhoods in the city-A, B and
C. He sells ranch style homes and two-story homes. Last year, 60% of his
sales were in neighborhood A, while neighborhood B made up 25% and
neighborhood C was 15% of the sales. Only 10% of the houses in
neighborhood A were ranches, compared with 40% for neighborhood B and
50% for neighborhood C. Suppose we randomly select
one of the homes he
sold in one of these three neighborhoods.
Draw a tree diagram of this chance process?

The probability tree will have three branches at start and then, each branch will have two more branches for ranch and two story houses.
Given information:
There are three cities A, B, and C.
The homes are of two types; two story and ranch.
The sales in A, B, and C is 60%, 25%, and 15%, respectively.
The ranch houses in A, B, and C are 10%, 40%, and 50% respectively.
So, the probability tree will have three branches at first. These three branches will have probability of 0.6, 0.25, and 0.15, for A, B, and C, respectively.
See the attached image.
Therefore, the probability tree will have three branches at start and then, each branch will have two more branches for ranch and two story houses.

Answers
The (A ∪ B) ∩ (A ∪ C) ∩ (B ∪ C) ∩ (B ∩ C) ∩ C is an empty set {}.To find the sets A ∪ B, A ∩ B, A ∪ C, A ∩ C, B ∪ C, and B ∩ C, we can perform the following operations:
A ∪ B: The union of sets A and B includes all unique elements from both sets, resulting in {10, 11, 12, 13, 14, 16}.
A ∩ B: The intersection of sets A and B includes only the common elements between the two sets, which are {10, 12}.
A ∪ C: The union of sets A and C combines all unique elements, resulting in {7, 8, 9, 10, 11, 12, 13}.
A ∩ C: The intersection of sets A and C includes only the common elements, which is {10, 11}.
B ∪ C: The union of sets B and C combines all unique elements, resulting in {7, 8, 9, 10, 11, 12, 14, 16}.
B ∩ C: The intersection of sets B and C includes only the common elements, which is an empty set {} since there are no common elements.
Finally, performing the remaining operations:
(A ∪ B) ∩ (A ∪ C): This is the intersection of the union of sets A and B with the union of sets A and C. The result is {10, 11, 12, 13} since these elements are common to both unions.
(B ∪ C) ∩ (B ∩ C): This is the intersection of the union of sets B and C with the intersection of sets B and C. Since the intersection of B and C is an empty set {}, the result is also an empty set {}.

Working on summer vacation. Suppose in a school it is found that 30% of adults do not work at all while on sum- mer vacation. In a random sample of 8 adults, let x repre sent the number who do not work during summer vacation.
a. For this experiment, define the event that represents a "success
b. Explain why x is (approximately) a binomial random variable.
c. Give the value of p for this binomial experiment.
d. Find P(x-3) e. Find the probability that 2 or fewer of the 8 adults do not work during summer vacation.
Answers
Answer:
(a) The event that represents success here is the percentage of adults who do not work at all while on summer vacation.
(b) X is a binomial random variable.
(c) The value of p for this binomial experiment is 0.30 or 30%.
(d) P(X = 3) = 0.2541.
(e) The probability that 2 or fewer of the 8 adults do not work during summer vacation is 0.5518.
Step-by-step explanation:
We are given that in a school it is found that 30% of adults do not work at all while on summer vacation. In a random sample of 8 adults, let X represent the number who do not work during summer vacation.
Let X = the number of adults who do not work during summer vacation
(a) The event that represents success here is the percentage of adults who do not work at all while on summer vacation.
(b) The conditions required for any variable to be considered as a random variable is given by;
The experiment consists of identical trials.Each trial must have only two possibilities: success or failure.The trials must be independent of each other.So, in our question; all these conditions are satisfied which means X is a binomial random variable.
(c) The value of p for this binomial experiment is 0.30 or 30%.
(d) The above situation can be represented through binomial distribution;
\(P(X = r) = \binom{n}{r}\times p^{r} \times (1-p)^{n-r}; x = 0,1,2,......\)
where, n = number of trials (samples) taken = 8 adults
r = number of success = exactly three
p = probability of success which in our question is % of adults who
do not work at all while on summer vacation, i.e; p = 0.25
SO, X ~ Binom(n = 8, p = 0.30)
Now, the probability that exactly 3 adults do not work at all while on summer vacation is given by = P(X = 3)
P(X = 3) = \(\binom{8}{3}\times 0.30^{3} \times (1-0.30)^{8-3}\)
= \(56 \times 0.30^{3} \times 0.70^{5}\)
= 0.2541
(e) The probability that 2 or fewer of the 8 adults do not work during summer vacation is given by = P(X \(\leq\) 2)
P(X \(\leq\) 2) = P(X = 0) + P(X = 1) + P(X = 2)
= \(\binom{8}{0}\times 0.30^{0} \times (1-0.30)^{8-0}+\binom{8}{1}\times 0.30^{1} \times (1-0.30)^{8-1}+\binom{8}{2}\times 0.30^{2} \times (1-0.30)^{8-2}\)
= \(1 \times 0.30^{0} \times 0.70^{8}+8 \times 0.30^{1} \times 0.70^{7}+28\times 0.30^{2} \times 0.70^{6}\)

(Give your answer rounded to one decimal place.)
Answers
The ideal congressional district size (Standard Divisor) in 1790 was 34437.33.
What is Standard divisor?The number of persons each House of Representatives seat represents is known as the "Standard Divisor" (SD). By dividing the total population of all the states by the total number of seats available for voting, the SD is determined. SD is calculated as Total U.S. Population / Total Number of Voting Seats.
The ratio of the entire population to the available seats (or other allocations) is known as the standard divisor. • The Hamilton system divides up any extra seats among the states with the largest fractional parts after allocating each state its lower quota initially.
Given,
population in 1790 was 3,615,920,
number of objects = 105
⇒ Standard divisor = total population / number of objects
⇒ Standard divisor = 3,615,920 / 105
⇒ Standard Divisor = 34437.33

The point (–3, –5) is on the graph of a function. Which equation must be true regarding the function?
a. f(–3) = –5
b. f(–3, –5) = –8
c. f(–5) = –3
d. f(–5, –3) = –2
Answers
Answer:
a. f(–3) = –5
Step-by-step explanation:
On a graph, point (x, y) can be also represented as function f (x) = y
it means that if f(x) has input value as x then its output value will be y.
Now given that in the problem that
The point (–3, –5) lies on the graph
it means that for function input value of of -3 has the out put value of -5
which can also be written as
f(-3) = -5
Hence the correct choice is a. f(–3) = –5.
there was 506 tickets sold for the school play they were either student tickets or adult tickets there was 56 more student tickets sold than adult tickets sold how many adult tickets were sold
Answers
Answer:
A = 228 tickets
Step-by-step explanation:
We need to set up a system of equation to find the number of adult tickets sold, where A represents the adult tickets and S represents the student tickets.
Because the number of adult and student tickets together equals 506, we have A + S = 506.
Because there are 56 more student tickets than adult tickets we have A + 56 = S
And the way the system is already set up allows us to use substitution.
Thus, we have:
\(A + S=506\\A+56 = S\\\\A+A+56 =506\\2A+56=506\\2A=456\\\\A=228\\228+56=S\\278=S\)
The number of student tickets was not necessary to find in this problem, but I found anyway just in case you wanted check the work or wanted to prove the validity of the values.

Find a unit vector with the direction of PQ
Answers
Answer:
The length of the vector is of \(\sqrt{194}\)
The unit vector with the direction of PQ is \((\frac{8}{\sqrt{194}}, \frac{9}{\sqrt{194}}, \frac{7}{\sqrt{194}}\)
Step-by-step explanation:
Vector from point P(3,-5,2) to Q(-5,4,9)
The vector is:
\(PQ = Q - P = (-5-3, 4-(-5), 9-2) = (8,9,7)\)
The length is:
\(\sqrt{8^2+9^2+7^2} = \sqrt{194}\)
The length of the vector is of \(\sqrt{194}\)
Find a unit vector with the direction of PQ
We divide each component of vector PQ by its length. So
\((\frac{8}{\sqrt{194}}, \frac{9}{\sqrt{194}}, \frac{7}{\sqrt{194}}\)
The unit vector with the direction of PQ is \((\frac{8}{\sqrt{194}}, \frac{9}{\sqrt{194}}, \frac{7}{\sqrt{194}}\)

The intersection point of the circle and the line is at-(2.68, 7.36).
What is defined as the equation of circle?A circle is a confined curve drawn from a fixed point known as the centre, with all points on the curve sharing the same distance as from centre point. (x-h)² + (y-k)² = r² is the equation for a circle with (h, k) centre and r radius.For the given question;
The equation of the line is; y = 2x + 2 ......eq 1
The centre of the circle (h,k) = (0,2)
The radius of the circle = 6 units.
This is the equation's standard form.
(x - h)² + (y - k)² = r²
Put the values in the formula;
(x - 0)² + (y - 2)² = r²
(x)² + (y - 2)² = r²
Put the value of y from eq 1.
(x)² + (2x + 2 - 2)² = 6²
(x)² + (2x)² = 36
Simplifying;
x = ±6/√5
But the intersection must be in first quadrant.
x = 6/√5 = 2.68
Put the value of x in eq 1.
y = 2x + 2
y = 2×2.68 + 2
y = 7.36
Thus, the coordinates of the intersection of the line and the circle are (2.68, 7.36).
