Step-by-step explanation:

Answer: -27

Step-by-step explanation: Use inductive reasoning to predict the most probable next number in the list.

3, 9, -3, 3, -9, -3, -15, -9, -21, ?

We can start by looking at the differences between consecutive terms in the list:

9 - 3 = 6 -3 - 9 = -12 3 - (-3) = 6 -9 - 3 = -12 -3 - (-9) = 6 -15 - (-3) = -12 -9 - (-15) = 6 -21 - (-9) = -12

Notice that the differences alternate between positive 6 and negative 12. This suggests that the pattern involves adding 6, then subtracting 12, and then adding 6 again. Applying this pattern to the last term in the list (-21), we get:

-21 + 6 = -15 -15 - 12 = -27 -27 + 6 = -21

Therefore, we predict that the most probable next number in the list is -27.

Answer:A.The triangles are similar but not congruent

Step-by-step explanation:

In a congruent traingle:

the both triangles are same in shape and size

There are five theorems to see if the triangles are congruent

and neither particularly applies here

sss: the sides are not equal

as none of the sides are equal, then despite the angles, congruence is not possible

However it is evident that one of the triangles is proportionally bigger than the other but similar. Hence A is correct.

Step-by-step explanation:

We will have that the function will be:

And since we know that the function follows:

We will have that m is the slope and b is the y-intercept.

From this, we have that the domain goes from (-infinity, infinity) and the range, goes from (infinity, -infinity).

We graph the function by replacing values for x and then solving for y, then we will have a point corresponding for each value of x, and then we link them. In our case since it is a line we will get a line with an slope of -5 and a y-intercept of 4.

3/13

The probability of being dealt a picture card is 3/13

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

The value of probability lies between 0 and 1

Given data ,

Let the total number of cards in the deck be = 52 cards

Let the number of picture cards be = A

Now , the picture cards include 4 colors of Jacks , 4 colors of Queens and 4 colors of Kings

So , total number of picture cards = 4 + 4 + 4

                                                        = 12 picture cards

And the probability of drawing a picture cards is P =
number of picture cards / total number of cards in the deck

The probability of drawing a picture cards is P = 12 / 52

                                                                               = 3 / 13

Therefore , the value of P is 3/13

Hence , The probability of being dealt a picture card is 3/13

3.1.3 The basic property of operations used is the associative property of addition.

3.1.1 The basic property of operations used in this calculation is the commutative property of multiplication. It states that the order of the factors in a multiplication problem can be rearranged without changing the product. In this case, the numbers 25 and 4 were swapped, resulting in the same product of 100.

3.1.2 The basic property of operations used in this calculation is the additive inverse property. It states that for any number, there exists an additive inverse such that when the number and its additive inverse are added together, the result is zero. In this case, adding 412 and its additive inverse (-412) results in zero.

3.1.3 The basic property of operations used in this calculation is the associative property of addition. It states that the grouping of numbers being added does not affect the sum. In this case, the numbers 25, 37, 20, 5, 30, and 7 were regrouped to facilitate easier mental addition. By grouping 25 and 37, and then grouping 20, 5, 30, and 7, the final sum of 62 is obtained, which is the same as adding all the numbers together in the original order.

1 Lecture 15: Rates of change

1.1 Outline

• Rates of change, velocity, acceleration.

• Marginal rates

• Equation of motion for objects falling under constant gravity

• Interpreting position and velocity graphs

1.2 Rates of change

If f(t) is a function depending on time, then we can write down the average rate of

change on an interval [t1, t2],

f(t2) − f(t1)

t2 − t1

.

We have defined the instantaneous rate of change at a time t as the limit

f

0

(t) = limr→t

f(r) − f(t)

r − t

.

This is also called the derivative. Thus, instantaneous rate of change is another name

for the derivative. In applications the name rate of change is more descriptive.

If s(t) gives the position of a particle as it moves along a line, then

v(t) = limk→0

s(t + k) − s(t)

k

gives the instantaneous velocity. If position is measured in meters and time in seconds,

the velocity v is measured in meters/second. We will abbreviate meters by m and

seconds by s so that the units for velocity are m/s.

As a second example, let v(t) be a function which gives the v

The probability that the first card drawn without replacement is a diamond and the second card drawn is red is approximately 0.12

The probability for an event without replacement implies that once an item is drawn, then we do not replace it back to the sample space before drawing another item.

In a standard deck of cards, there is a total of 52 cards with 13 diamonds and 26 reds (including diamonds)

probability that the first card drawn is diamond = 13/52

probability that the first card drawn is red = 25/51 {because diamond is also a red and was drawn first without replacement}

So;

probability that the first card is a diamond and the second card is red = (13/52) × (25/51)

probability that the first card is a diamond and the second card is red = 325/2652

probability that the first card is a diamond and the second card is red = 0.1225

Therefore, the proprobability that the first card drawn without replacement a diamond and the second card is red is approximately 0.12

The given table does not represent a function. The correct answer is D. No, because one x-value corresponds to two different y-values.

To determine if the table represents a function, we need to check if every x-value corresponds to exactly one y-value. Let's analyze the given table:

x | y

-------

O | 1

X | 4

2 | 3

3 | 2

3 | 5

4 |

5 |

From the table, we can see that the x-values are not unique. Both the values 3 and 4 appear twice in the x-column, but they have different corresponding y-values.

This violates the definition of a function, which states that each input (x-value) should have only one output (y-value).

Therefore, the given table does not represent a function.

The correct answer is D. No, because one x-value corresponds to two different y-values.

Answer:

189 cm³

Step-by-step explanation:

Volume of the object equals the volume of water increased. To find the volume of the water that increased, subtract the volume of water after increasing from the volume of water before increasing.

           l = 9 cm ; w = 6 cm ; h = 7 cm

          \(\boxed{\text{\bf Volume of rectangular prism = l*w*h}}\)

                                                             V₁ = 9 * 6 * 7

                                                                 =   378 cm³

         l = 9 cm ; w = 6 cm ; h = 7 + 3.5 = 10.5 cm

            V₂ = 9 * 6 * 10.5

                 = 567 cm³

Volume of the water that increased = V₂ - V₁

                                                           = 567 - 378

                                                            = 189 cm³

Volume of the object = 189 cm³

The height of the candle after 14 hours given the linear function of the amount of time in hours it has been burning is 23.6 centimeters.

Let

Height is a linear function of time

Y = mx + b

where,

We can calculate the slope from the given values

(5, 24.5) and (18, 23.2)

Slope = (y2 - y1) / (x2 - x1)

= (23.2 - 24.5) / (18 - 5)

= -1.3 / 13

= -0.1

y = mx + b

24.5 = -0.1(5) + b

24.5 = -0.5 + b

24.5 + 0.5 = b

25 = b

y = mx + b

23.2 = -0.1(18) + b

23.2 = -1.8 + b

23.2 + 1.8 = b

25 = b

So therefore,

The height of a candle after 14 hours can be calculated by substituting all the unknown values.

y = mx + b

y = -0.1(14) + 25

y = -1.4 + 25

y = 23.6 centimeters

The cost per ounce of the premium walnut is $0. 23

To determine the value of the cost, we need to note that proportion is simply described as the comparison of numbers such  that they are made equal to another.

From the information given, we have that;

54 ounces of premium walnuts costs $12.95

This is represented as;

54 ounces = $12. 95

Then 1 = x

cross multiply the values, we get;

x = $12.95/54

Divide the values, we get;

x = $0. 23
