what is the relative humidity of the parcel at sea level on the leeward side? (fill in only the letter: a, b, c, or d, all caps) a) 25%, b) 33%, c) 100%, or d) 58%
The relative humidity of the parcel at sea level on the leeward side is 58% that is option D
The amount of water vapour in an air-water mixture relative to the maximum amount is known as relative humidity (RH). RH is a comparison between the humidity of a specific water-air mixture and the saturation humidity ratio at a particular temperature (dry-bulb)
By deducting the temperature on the wet-bulb thermometer from the temperature on the dry-bulb thermometer and utilizing a relative humidity chart, one may determine the relative humidity.
The relative humidity of the parcel at sea level on the leeward side is 58%

A lake fishing map is laid out on a coordinate plane with each unit equal to 1 mile. The boat is launched from the point (-5, 0) and goes to point (-5, 5) to fish. From
there, the boat travels to (0, 0) to fish and then goes back to the launch point
Determine the total number of miles traveled. Round to the nearest whole number.
05 miles
07 miles
O17 miles
O50 miles
The total number of miles traveled is given by the following option:
17 miles.
How to obtain the total distance?The total distance is divided into three parts, obtained as follows:
First part: From point (-5,0) to point (-5,5).Second part: From point (-5,5) to point (0,0).Third part: From point (0,0) back to the launch point of (-5,0).The generic notation of two points is given as follows:
[tex](x_1,y_1), (x_2,y_2)[/tex]
The distance between two points is then given by the equation presented as follows:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Hence each distance in this problem is given as follows:
First part: 5 miles.Second part: 7 miles.Third part: 5 miles.The total distance is the sum of each distance, hence it is given as follows:
5 miles + 7 miles + 5 miles = 17 miles.

Each bag of cereal should contain 350 grams. a box was selected at ramdon and weighed 342 grams. what is the percent error?
The percentage error in selecting the random box is 2.285 %
Let the total amount of bag of cereal be = 350 grams
The box selected at random had a weight of = 342 grams
We know the formula of percentage error.
The percentage error is calculated by the formula
Percentage Error =
( ( Original Value - Observed Value ) / Original Value ) x 100
Plug the values in above formula:
Percentage Error = ( ( 350 - 342 ) / 350 ) x 100
= ( 8 / 350 ) x 100
= 0.02285 x 100
= 2.285 %

What is permutation and combination?
The process of placing all the components of a set into a certain sequence or order is known as permutation in mathematics. In other terms, the process of permuting is the reordering of the components of a set if the set is already ordered. Nearly all areas of mathematics involve permutations in some form or another. They frequently appear when various orderings on particular finite sets are taken into account.The combination is a way of selecting items from a collection, such that (unlike permutations) the order of selection does not matter. In smaller cases, it is possible to count the number of combinations. Combination refers to the combination of n things taken k at a time without repetition. To refer to combinations in which repetition is allowed, the terms k-selection or k-combination with repetition are often used.[tex]$11xy,\qquad 1x1y,\qquad1xy1$[/tex]
Because the number must have exactly two identical number digits,[tex]$x\neq y$[/tex], [tex]$x\neq1$, and $y\neq1$[/tex]. Hence, there are [tex]$3\cdot9\cdot8=216$[/tex] number of this form.
Now suppose that the two identical digits are not 1. Reasoning similarly to before, we have the following possible combination:

Again,,[tex]$x\neq y$[/tex], [tex]$x\neq1$, and $y\neq1$[/tex]. There are [tex]$3\cdot9\cdot8=216$[/tex] numbers of this form.

Answer:

Step-by-step explanation:
Horizontal lines are parallel so as suggested in:
1. Vertical angles are congruent, so 5a = 115.
2. Alternate interior angles are congruent, so b - 12 = 65.
3. Corresponding angles are congruent and linear angle pairs sum up to 180, so (b-12) + 65 = 180.
However, alternate interior angles are congruent,
as stated in 2nd suggestion too, so the sum is not 180 but 130.
Therefore 4th suggestion is not correct.
how many four-digit numbers greater than 2999 can be formed such that the product of the middle two digits exceeds 5?
The 3360 possible four-digit numbers are greater than 2999.
What is the combination?
A combination in mathematics is a choice made from a group of separate elements where the order of the selection is irrelevant.
We know it has to be a four-digit number,
The first digit has to be between 3 and 9 (inclusive) so there are 7 options.
The unit digit can be any number so there are 10 options.
The answer will be 7 * (# of possible middle digit combos) * 10.
There are 7*48*10 = 3360 possible four-digit numbers.

What is a scrum?
Scrum is a project management framework that was initially focused on software development, while it has now been applied to other areas such as research, sales, marketing, and cutting-edge technology.
It is intended for groups with ten or fewer members who divide their work into tasks that can be finished in sprints, which are time-boxed iterations that can be done in as little as one month and most frequently two weeks.
If the frequency was reduced to every two or three days, there would be three issues.
(A) The chances to review and modify the Sprint Backlog may be missed.
(B) The Sprint plan becomes imprecise; obstacles are raised and removed more slowly.
(C) Too much time is spent before meetings updating the scrum board.

g(x) = 2x² - 1
f(g(x)) means that x is first processed by g, and then the result of that is processed by f.
