Answer:
The moment when Minerva disguises Ulysses as an old beggar.
Explanation:
Which of the following is an example of chemical control of nonnative species? a. mowing b. herbicides c. net barriers d. inspections Please select the best answer from the choices provided A B C D
Answer:
B. Herbicides
Explanation:
Nonnative species are species that are found outside their natural habitat. They are also called foreign species. They are introduced through the activities of man either deliberately or in-deliberately . They can be controlled by chemical, biological and mechanical means.
Mowing, net barriers and inspections are mechanical controls.
Biological control is the deliberate introduction of natural enemies of these nonnative/foreign species.
The use of herbicides is a chemical control of plants that grow where they are not wanted.
Answer:
Example of Chemical Control of Non-native species.
B) Herbicides
Explanation:
In the given options, all of them are can be used to remove or control non-native species. but among them only Herbicides is the chemical solution to control non-native species.
Herbicides are chemicals that are used to kill unwanted plants, which can be taken as non-native species.
Some of the herbicides kill the unwanted plants while leaving the desired crops unharmed, some interfere with the growth of such species while some kill all the plant material with which they come in contact with

The number of tickets purchased by an individual for Beckham College’s holiday music festival is a uniformly distributed random variable ranging from 2 to 10. Find the mean and standard deviation of this random variable. (Round your answers to 2 decimal places.)
Answer:
The mean of the distribution is 4.00 and the standard deviation is 2.31
Explanation:
Given
Range = 2 to 10
Type of distribution = uniform distribution
Required
1. Mean
2. Standard Deviation
The mean of uniform distribution is calculated as thus;
[tex]Mean = \frac{1}{2}(a + b)[/tex]
Where b and a are the intervals of the distribution
b = upper bound = 10
a = lower bound = 2
So,
[tex]Mean = \frac{1}{2}(a + b)[/tex]
Substitute 10 for b and 2 for a
[tex]Mean = \frac{1}{2}(2 + 10)[/tex]
[tex]Mean = \frac{1}{2}(12)[/tex]
[tex]Mean = \frac{1}{2} * 12[/tex]
[tex]Mean = 6[/tex]
[tex]Mean = 6.00[/tex] (Approximated to 2 decimal places)
The standard deviation of uniform distribution is calculated as thus;
σ = √σ²
Where σ represents the standard deviation and σ² represents the variance.
Calculate variance
σ² = Var
[tex]Var = \frac{(b-a)^2}{12}[/tex]
Substitute 10 for b and 2 for a
[tex]Var = \frac{(10 - 2)^2}{12}[/tex]
[tex]Var = \frac{8^2}{12}[/tex]
[tex]Var = \frac{64}{12}[/tex]
[tex]Var = 5.33[/tex]
Recall that
σ = √σ² = √Var
Substitute 5.33 for Var
σ = √5.33
σ = 2.309401076758503
σ = 2.31 (Approximated)
Hence, the mean of the distribution is 4.00 and the standard deviation is 2.31

Complete question reads;
3. It's most accurate to say that hand-tied arrangements
A. are especially popular for weddings.
B. include only one or two floral materials.
C. are difficult to carry.
D. require a concealed water supply.
Answer:
B. include only one or two floral materials.
Explanation:
Remember, when flowers are been arranged by a florist consideration is made to allow for efficient handling. This involves using a few flower stems and constructing them using one’s hand to form the arrangement. The stems therefore would form a handle which could be held, thus only one or two floral materials are used.
