1. If A, then B: True. 2. If B, then A: False. 3. A if and only if B: True.  A and B must both be true for the third statement to be true.

In this scenario, we are presented with a pair of statements A and B. For each pair, we must determine if the following three sentences are true or false: 1. If A, then B. 2. If B, then A. 3. A if and only if B. The first statement is true if statement A is true and statement B is true. The second statement is false if statement A is true and statement B is false. The third statement is true if both statements A and B are true. To determine this, we must consider both statements A and B to see if they are both true or false. If both are true, then statement 3 is also true. If either statement A or B is false, then statement 3 is false. Therefore, if both statements A and B are true, then the third statement is true, otherwise, it is false.

There are 284 adults who ate pizza.

The way that sets are represented by a person is always the same: as a group of clearly defined objects or elements. A capital letter designates a set. The cardinal number of a set is the number of elements in the finite set.

Given  A survey of 518 adults,

let  T denote TV, H for out with friends, and P for pizza

and given, n(T ∪ H ∪ P) = 518

n(T) = 175, n(H) = 181

n(P) = to find

TP = 39, TH = 26

FP = 39, n(TPH) = 42

n(TP) = 39 + 42 = 81

n(TH) = 26 + 42 = 68

n(HP) = 39 + 42 = 81

using the formula of triple intersection,

 n(T U H U P) = n(T) + n(H) + n(P) - n(TH)   - n(TP)   - n(HP)   + n(TPH).

518 - 66 = 175 + 181 + n(P) - 81 - 68 - 81 + 42

n(P) = 452 - 168

n(P) = 284

Answer:

Sn for an arithmetic series can be found using the formula: Sn = (n/2) * (a1 + an). In this case, we have:

a1 = 3, an = 42, n = 14

Sn = (14/2) * (3 + 42) = (14/2) * 45 = 315

Sn for an arithmetic series can be found using the formula: Sn = (n/2) * (a1 + an). In this case, we have:

a1 = -20, an = 148, n = 25

Sn = (25/2) * (-20 + 148) = (25/2) * 64 = 800

Sn for an arithmetic series can be found using the formula: Sn = n/2 * (2a1 + (n-1)d) where d is the common difference. In this case, we have:

a1 = 5, n = 13, d = 1/2

Sn = 13/2 * (2 * 5 + (13 - 1) * 1/2) = 13/2 * (10 + 12/2) = 13/2 * (10 + 6) = 13/2 * 16 = 104

So for the series with the given parameters, Sn = 104.

A path between two classrooms that takes no longer than 15 minutes and maximizes the amount of shade cover.

This problem can be solved using a Shortest Path Algorithm, which is a type of algorithm that finds the shortest path between two nodes in a graph. To solve this problem, reasonable assumptions to make include: the walking speed is constant, the walking path is a straight line, and the amount of shade cover is quantifiable.

The algorithm can be modeled using a weighted graph, where the nodes are the university classrooms, and the edges are the paths between them. The weights of the edges represent the length of the path in terms of time, and the amount of shade cover. The algorithm will then search through the graph, finding a path between the two nodes that optimizes the amount of shade cover while still maintaining a total path length of no more than 15 minutes.

The algorithm can then be implemented using two loops. The outer loop will iterate through each of the nodes and the inner loop will iterate through each of the edges connecting the nodes. For each iteration, the algorithm will check if the total path length is less than 15 minutes and if the amount of shade cover is greater than the current best path. If both conditions are met, the algorithm will save the path as the best path and update the current best path length and shade cover

By using this algorithm, we can find a path between two classrooms that takes no longer than 15 minutes and maximizes the amount of shade cover.

The arithmetic sequence is A = 14 , 11 , 8 , 5 , ...

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the arithmetic sequence be represented as A

Now , the equation will be

The first term of the AP is a₁ = 14

The common difference of the AP is d = -3

So , the second term of the AP is a₂ = a + d

a₂ = 14 - 3 = 11

The third term of the AP is a₃ = a + 2d

a₃ = 14 - ( 6 ) = 8

The fourth term of the AP is a₄ = a + 3d

a₄ = 14 - ( 9 ) = 5

The ratio (fraction or proportion) of the number of times a data value occurs in the set of all outcomes to the total number of outcomes is referred to as the relative frequency.

If we are given the curve of a normal distribution data, then the relative frequency of an endpoint  is equal to the area to the left of that point. Therefore, we can conclude:

a) The relative frequency of scores between A and B is 13% or 0.13

b) C is the mean of the data. Hence, the relative frequency of scores between A and C is 50% or 0.5

c) The relative frequency between scores B and C is  50% - 13% = 37% or 0.37.

Step-by-step explanation:

If we want to make a row of three triangles, we need to use 7 stirrers, so each triangle uses 7 stirrers / 3 triangles = 2 stirrers/triangle.

If we have 780 biodegradable stirrers in the box, we could make 780 stirrers / 2 stirrers/triangle = 390 triangles.

So we could make a row of 390 triangles / 3 triangles/row = 130 rows of three triangles.

Add the area of each face together

Don't forget the units!

Let's start by finding the right face (12 by 3). From your picture, we can tell its 12m long, and 3m tall. To find the aria of any face, we multiply the length, times the width.
12 x 3 = 36.
Now let's look at where it says 8m. Since that face is just as tall as the first one, we can tell its 3m tall.
8 x 3 = 24.

We can continue this for the top face.
Since the width of the second face we did is 8m, and the width of the first one is 12m, we can tell that the top one is 8 x 12. (96).

We can do this again for the other 3 sides.
A shortcut i like to take, is to do 3 of the sides, (Like the ones we did) and add them together, then double the sum.

36+24+96=156.

156x2=312.

This shortcut should work, because by adding the aria of half the sides together, we get exactly half the answer.

When doing this, it only works to do 3 different sides. it will not work if you do the same side twice, or a parallel side.

I encourage you to let me know if this method works for you! I hope this helps!

The linear equation Maya solves, 5·x + 7 = -5·x + 7, indicates that we get x = 0. The correct option is therefore;

A linear equation is an equation of the form; y = m·x + c, where, m is the slope and c is the y-value of the intercept of the graph of the equation with y-axis, known as the y-intercept.

The specified equation can be presented as follows;

5·x + 7 = -5·x + 7

Adding 5·x to both sides of the equation, we get;

5·x + 5·x + 7 = -5·x + 5·x + 7

Collecting and adding like terms, is obtained as follows;

10·x + 7 = 0 + 7

Adding 7 to both sides of the equation, we get;

10·x + 7 - 7 = 0 + 7 - 7

10·x + 0 = 0 + 0 = 0

Suppose that you observe that when the price of cigarettes rises by 10%, the quantity of cigarettes purchased falls by 8.7%. this implies that cigarettes are price inelastic in demand and that the price elasticity of demand is equal to 0.87.

The degree to which use of a product changes in response to changes in its price is known as price elasticity of demand. If a product's price elasticity of demand were extremely low, or even zero, then demand would only barely increase or decrease in reaction to price changes.

If price elasticity of demand for a good were about 1.0, then demand for that good would fall by 1% for every 1% increase in price. For every 10% price increase, demand would decrease by 10%, by 20% for a 20% price increase, by 100% for a 100% price increase, and so on.
