some values of exponental functions A and B are shown in the table and graph below.which of the following deacribes the y intercept of the two functions.

No, there are x values which map to more than 1 y-value.

Given that Matthew examines the relation as shown in the below.

{(4, -11), (3,1), (0,1), (2,6), (3, -1)}

We need to check whether the relation is a function or not,

So, we know that,

A relation can map inputs to multiple outputs. It is a function when it maps each input to exactly one output. The set of all functions is a subset of the set of all relations.

If any x values are repeated, and the corresponding y values are different, then we have a relation and not a function.

Here we can see that the y values are repeated, so it is not a function.

Answer:

Step-by-step explanation:

Answer:

1. Square

A square has 4 side of equal lengths, and all right angles.

2. Triangle

A triangle has 3 sides and 3 angles. It could either be an isosceles, equilateral or obtuse triangle.

3. Rectangle

A rectangle has 4 sides. 2 are parallel and the other 2 are parallel. All angles are 90 degrees.

4. Trapezoid

This shape has 4 sides. Only 1 pair of sides is parallel. The other 2 sides are not parallel

5. Parallelogram

It has 4 sides, and both pair of opposite sides are parallel.

The solution to the simultaneous equations is x = 2 and y = -4. To obtain these values,  18 = 7x - y  is rearranged to y = 7x - 18, and then substituted into 3x + y = 2  to obtain the value of x and y.

Rearranging equation (1) to make y the subject

18 = 7x - y

Add y to both sides

18 + y = 7x

Subtract 18 from both sides

y = 7x - 18

Using the answer to part a) to solve the simultaneous equations

Substitute the expression for y from equation (1) into equation (2)

3x + (7x - 18) = 2

Simplify

10x - 18 = 2

Add 18 to both sides

10x = 20

Divide both sides by 10

x = 2

Substitute x = 2 into equation (1) to find y

18 = 7(2) - y

18 = 14 - y

Subtract 14 from both sides

4 = -y

Multiply both sides by -1

-4 = y

Therefore, the solution to the simultaneous equations is x = 2 and y = -4.

Answer:

∠ BDC = 29°

Step-by-step explanation:

the sides of a rhombus are congruent, so CD = ED and Δ EDC is therefore isosceles with base angles congruent , then

∠ BCD = ∠ BED = 61°

• the diagonals are perpendicular bisectors of each other , then

∠ CBD = 90°

the sum of the 3 angles in Δ BCD = 180°

∠ BDC + ∠ CBD + ∠ BCD = 180°

∠ BDC + 90° + 61° = 180°

∠ BDC + 151° = 180° ( subtract 151° from both sides )

∠ BDC = 29°

The statement (p and (p => q)) => q) is not a contingency because of it evaluating to only true while a contingency statement includes both true values and some false values.

Contingency is a statement in which there are some true and some false values for every value of its propositional variables.

The statement given is (p and (p => q)) => q), or in more symbolic way, it is: ((p ∧ (p → q)) → q)

Now, let we evaluate it for p = False, and q = False.

Then we get:

(p → q) = T (as False implied False)

Now, (p ∧ (p → q))  is F and T which is F

Then, ((p ∧ (p → q)) → q)  is F  → F which is True, or T.

Thus, p = F,and q = F makes  ((p ∧ (p → q)) → q)  = T

Similarly, the truth table for the statement (p and (p => q)) => q) or simply  ((p ∧ (p → q)) → q) is:

p q ((p ∧ (p → q)) → q)

F F T

F T T

T F T

T T T

Since all the values are true, thus, this isn't a contingency.

Thus, the statement (p and (p => q)) => q) is not a contingency because of it evaluating to only true while a contingency statement includes both true  values and some false values.

The probability of winning this game is 0.003

Let us name p to be the probability of winning the game.

We have the expected value to be 100

100 = probability of winning + 1-p x loss

win = 100000 - 200

We then input in the formula

100 = p*99800 +(1-p) x -200

100 = 99800p - 200 + 200p

Collect like terms

100 + 200 = 99800 + 200p

300 = 100000p

Divide through by 100000

This give the

Answer:

4.125 or 4 1/8 or 33/8

Step-by-step explanation:

Find the LCD and then combine.

a) Approximately 77.94% of possums have heads less than 95.4 mm.

b) Approximately 96.93% of possums have heads more than 85.8 mm.

c) Approximately 74.93% of possums have heads between 85.8 and 95.4 mm.

d) The maximum head length of the shortest 10% of possum heads is approximately 87.68 mm.

a) We can use the normal distribution to answer this question. Let X be the head length of a brushtail possum. Then X has a normal distribution with mean μ = 92.6 mm and standard deviation σ = 3.6 mm. We want to find P(X < 95.4 mm).

Using the standard normal distribution table or a calculator, we can find the z-score corresponding to a head length of 95.4 mm:

\(z = \frac{(95.4 - 92.6)}{3.6} = 0.78\)

Then, using the standard normal distribution table, we can find the probability that a standard normal variable is less than 0.78:

P(Z < 0.78) = 0.7794

Therefore, approximately 77.94% of possums have heads less than 95.4 mm.

b) Again, using the normal distribution with mean μ = 92.6 mm and standard deviation σ = 3.6 mm, we want to find P(X > 85.8 mm).

Finding the corresponding z-score:

\(z = \frac{(85.8 - 92.6)}{3.6} = -1.89\)

Using the standard normal distribution table, we find:

P(Z > -1.89) = P(Z < 1.89) = 0.9693

Therefore, approximately 96.93% of possums have heads more than 85.8 mm.

c) To find the percentage of possums with heads between 85.8 and 95.4 mm, we can subtract the probability of heads less than 85.8 mm from the probability of heads less than 95.4 mm:

P(85.8 < X < 95.4) = P(X < 95.4) - P(X < 85.8)

Using the same calculations as in parts (a) and (b), we get:

P(85.8 < X < 95.4) = 0.7794 - 0.0301 = 0.7493

Therefore, approximately 74.93% of possums have heads between 85.8 and 95.4 mm.

d) We want to find the maximum head length of the shortest 10% of possum heads. This is equivalent to finding the 10th percentile of the distribution. Using the normal distribution with mean μ = 92.6 mm and standard deviation σ = 3.6 mm, we want to find the head length x such that P(X < x) = 0.1.

Using the standard normal distribution table or a calculator, we can find the z-score corresponding to the 10th percentile:

P(Z < z) = 0.1

z = -1.28

Then, we can find the corresponding head length x:

x = μ + zσ = 92.6 + (-1.28)(3.6) = 87.68

Therefore, the maximum head length of the shortest 10% of possum heads is approximately 87.68 mm.

The marginal frequency of students who chose dancing is 37.

The correct answer to the given question is option 3.

The marginal frequency of students who chose dancing can be calculated by adding up the number of students who chose dancing in each row or column. In this case, we need to add up the number of art students who chose dancing (22) and the number of music students who chose dancing (15), which gives us a total of 37. This is the marginal frequency of students who chose dancing.

Based on the survey results, it appears that a slightly higher percentage of art students prefer dancing (41.5%) compared to music students (31.9%). However, both groups of students seem to be fairly evenly split between dancing and playing sports, with a slight preference for playing sports overall.

It's worth noting that cardiovascular activity is important for overall health and well-being, and both dancing and playing sports can provide great opportunities for exercise and physical activity. Additionally, both activities can also be enjoyable and provide a sense of community and social connection, which is important for middle school students who are still developing their social skills and relationships. Ultimately, the choice between dancing and playing sports will depend on individual interests, preferences, and abilities.
