STEP 2: Complete the table

Hence, the table for the equation will be:

Answer:

The answer is -4 as the correct slope for Find the slope:

(-1, 5), (2, -7)

Step-by-step explanation:

The average rate of change over the interval x = 3 and x = 7 is 30

The average rate of change of a function, graph, table or ordered pair is simply the slope of the relation

The equation is given as

g(x) = 2ˣ - 1

The interval is given as:

x = 3 and x = 7

Start by calculating g(3) and g(7)

So, we have

g(3) = 2³ - 1 = 7

g(7) = 2⁷ - 1 = 127

So, the average rate over these intervals is calculated as:

Average rate = [g(b) - g(a)]/[b - a]

This gives

Average rate = [g(7) - g(3)]/[7 - 3]

Substitute known values

Average rate = [127 - 7]/[7 - 3]

Simplify

Average rate = 120/4

Average rate = 30

Hence, the average rate of change is 30

A)The actual distance between towns K and L is 10 cm .

B) The bearing of town L from town k is 117 degree

The length of the line segment connecting the two sites is used to measure distance between them. The shortest line segment between a point and a line will have a length equal to the distance between them.

The following list includes four distance metrics that are maybe the most often employed in machine learning: the Hamming Distance. Distance in Euclid. New York City distance

The distance a number is from 0 on the number line is its absolute value. Because -7 is 7 units away from 0, its absolute value is 7. Because it is 5 units away from 0, the number 5 has an absolute value of 5. Any number that is less than zero is considered to be negative.

The given information is:

- They surveied 164 pet owners

- 61 own a dog

- 66 own a cat

- 11 own both a dog and a cat

We have to find how many owned neither a cat nor a dog.

We can represent this survey in the following diagram:

The people who own neither a dog nor a cat are 26.

Since f is the number of female cousins and the number of male cousins is 4 less than the number of female cousins, we can write the following expression to represent the number of male cousins:

For example, if the number of female cousins is 7, we can use this value (f = 7) in the expression above to find the number of male cousins:

So if the number of female cousins is 7, the number of male cousins is 3.

Therefore the expression for the number of boy cousins is f - 4.

Explanation:

Surface area of square pyramid = base area of square + area of 4 triangular faces

Area of square base = l^2

where

l is the length of each side of the square base

From the information given,

l = 8

Area of square base = 8^2 = 64

Area of each triangular face = 1/2 x base x height

We would find the height of each face by applying Pythagorean theorem to the right triangle formed below. It is ex[ressed as

hypotenuse^2 = one leg^2 + other leg^2

hypotenuse = 10

one leg = 4

other leg = h

4^2 + h^2 = 10^2

36 + h^2 = 100

h^2 = 100 - 36 = 64

h = √64

h = 8

base = 8

Area of 4 triangular faces 4 x 1/2 x 8 x 8 = 128

Surface area of square base pyramid = 128 + 64 = 192 in^2

We would convert 192 in^2 cm^2

Recall,

1 inch^2 = 6,4516 cm^2

192 inch^2 = 192 x 6.4516

= 1239 cm^2

She will need 1239 cm^3 of foil

You have to calculate the probability of obtaining an odd number after rolling the die and obtaining tail after tossing a coin, symbolically:

Where

"O" represents the event " rolling an odd number"

"T" represents the event "tossing a coin and obtaining tail"

The events are independent, which means that the intersection between both events is equal to the product of the individual probability of each event:

So, first, we have to calculate the probabilities of "rolling an odd number" P(O) and "tossing a coin and obtaining tail" P(T)

-The die is six-sided and numbered from 1 to 6, assuming that each possible outcome has the same probability, we can calculate the probability of rolling one number (N) as follows:

The possible outcomes when you roll a die are {1, 2, 3, 4, 5, 6}

Out of these six numbers, three are odd numbers {1, 3, 5}, this is the number of favorable outcomes of the event "O", and the probability can be calculated as follows:

So, the probability of rolling an odd number is P(O)=1/2

-When you toss a coin, there are two possible outcomes: "Head" and "Tail", assuming that both outcomes are equally possible.

For the event "toss a coin and obtain tail" there is only one favorable outcome out of the two possible ones, so the probability can be calculated as:

The probability of tossing a coin and obtaining a tail is P(T)=1/2

Once calculated the individual probabilities you can determine the asked probability:
