Let's calculate the products and check if they indeed have the same value:

Product of 32 and 46:

32 * 46 = 1,472

Reverse the digits of 23 and 64:

23 * 64 = 1,472

As you mentioned, the products are the same. This phenomenon is not unique to this particular pair of numbers. In fact, it occurs with any pair of two-digit numbers whose digits, when reversed, are the same as the product of the original numbers.

To find two other pairs of two-digit numbers that have this property, we can explore a few examples:

Product of 13 and 62:

13 * 62 = 806

Reversed digits: 31 * 26 = 806

Product of 17 and 83:

17 * 83 = 1,411

Reversed digits: 71 * 38 = 1,411

As for determining if a given pair of two-digit numbers will have this property without actually performing the multiplication, there is a simple rule. For any pair of two-digit numbers (AB and CD), if the sum of A and D equals the sum of B and C, then the products of the original and reversed digits will be the same.

For example, let's consider the pair 25 and 79:

A = 2, B = 5, C = 7, D = 9

The sum of A and D is 2 + 9 = 11, and the sum of B and C is 5 + 7 = 12. Since the sums are not equal (11 ≠ 12), we can determine that the products of the original and reversed digits will not be the same for this pair.

Therefore, by checking the sums of the digits in the two-digit numbers, we can determine whether they will have the property of the products being the same when digits are reversed.

The value of the question mark in the function is machine is 3

From the question, we are to calculate the value of the unknown number is the given image.

In the given image, we have a function machine and the unknown number is denoted by a question mark.

The given function is

-2 × ? × -3 = -18

Let the unknown number be x

Then, we can write that

-2 × x × -3 = -18

Multiply the numbers on the left hand side of the equation, we get

-6 × x = -18

Divide both sides by -6

(-6 × x) / -6 = -18 / -6

x = 3

Hence, the value is 3

Each student's clay pyramid should have a height of 5 inches in order to have the same volume.

To ensure that each student's clay pyramid has the same volume, we can calculate the required height for each pyramid.

Given that the length and width of the base are both 3 inches and the desired volume is the same for all pyramids, we can use the formula for the volume of a pyramid:

[V = rac {1}{3} times text{Base Area} times text{Height}]

Let's calculate the volume of the pyramid with the given dimensions:

V = frac{1}{3} times (3 times 3) times 5 = 15 text {cubic inches}

Since we want each student's pyramid to have the same volume, each student's pyramid should also have a volume of 15 cubic inches.

Now, let's calculate the required height for each student's pyramid. We can rearrange the volume formula to solve for the height:

[15 =frac{1}{3} times (3 times 3) times text{Height}

Simplifying the equation:

[15 = 3 times text{Height}]

Dividing both sides by 3:

[5 = text{Height}]

Therefore, each student's clay pyramid should have a height of 5 inches in order to have the same volume.

The solution to the compound inequality 2X - 18 ≥ 122 or 5X + 15 ≤ 250 is X ≤ 47 or X ≥ 70.  The mile marker X that will determine the conclusion of the research is any value of X greater than or equal to 70 or any value of X less than 47.

The insurance data scientist is trying to determine a conclusion about a certain stretch of a rural highway. To do this, they are investigating two conditions that could impact the safety of drivers on that highway.

These conditions are represented by two inequalities:

2X - 18 ≥ 122

5X + 15 ≤ 250

To determine the conclusion of their research, the data scientist needs to find the values of X that satisfy at least one of these inequalities.

Let's start by solving the first inequality:

2X - 18 ≥ 122

2X ≥ 140

X ≥ 70

This means that if the mile marker is greater than or equal to 70, then the condition represented by the first inequality is satisfied. Specifically, if the mile marker is at or beyond mile marker 70, then the insurance data scientist concludes that the condition represented by the first inequality is a concern for drivers on the highway.

Next, let's solve the second inequality:

5X + 15 ≤ 250

5X ≤ 235

X ≤ 47

This means that if the mile marker is less than or equal to 47, then the condition represented by the second inequality is satisfied. Specifically, if the mile marker is at or before mile marker 47, then the insurance data scientist concludes that the condition represented by the second inequality is a concern for drivers on the highway.

To summarize, the insurance data scientist needs to investigate the mile markers between 47 and 70 to determine if either condition is a concern for drivers on the highway. If the mile marker is at or before mile marker 47 or at or beyond mile marker 70, then the data scientist concludes that at least one of the conditions is a concern for drivers on the highway.

In conclusion, the solution to the compound inequality 2X - 18 ≥ 122 or 5X + 15 ≤ 250 is X ≤ 47 or X ≥ 70. The insurance data scientist needs to investigate the mile markers between 47 and 70 to determine if the conditions represented by either inequality are a concern for drivers on the highway.

Answer:

0.9168

Step-by-step explanation:

From the data given:

Mean = 110

standard deviation = 5

Let consider a random sample n =49 which have a mean between 109 and 112.

The test statistics can be computed as:

\(Z_1 = \dfrac{x- \bar x}{\dfrac{\sigma}{\sqrt{n}}}\)

\(Z_1 = \dfrac{109- 110}{\dfrac{5}{\sqrt{49}}}\)

\(Z_1= \dfrac{-1}{\dfrac{5}{7}}\)

\(Z_1\)  = -1.4

\(Z_2= \dfrac{x- \bar x}{\dfrac{\sigma}{\sqrt{n}}}\)

\(Z_2 = \dfrac{112- 110}{\dfrac{5}{\sqrt{49}}}\)

\(Z_2 = \dfrac{2}{\dfrac{5}{7}}\)

\(Z_2 =2.8\)

Thus; P(109  <  \(\overline x\)  <  112) = P( - 1.4 < Z < 2.8)

= P(Z < 2.8) - P( Z < -1.4)

= 0.9974 - 0.0806

The value of both domain and range of this exponential function is (−∞,∞).

y = 2x-9

The domain of the function can be defined as all real numbers except the ones where the expression is undefined. In the case of 2x-9, there is no real number for which this expression is undefined. Therefore, a domain of this exponential function is (−∞,∞).

The range of the function is defined as the set of all valid y values. In this case, all real numbers are valid values of y. Therefore, the range of this exponential function is (−∞,∞).

Therefore, domain of y = 2x-9 is (−∞,∞) and range is also (−∞,∞).

To find the values on the interval [0, 2π) where the two fish will be at the same height above the water, we need to find the values of x that satisfy the equation f(x) = g(x).

Given:

f(x) = 2sin(2x - 1)

g(x) = cos(x)

We can solve this by plotting the two equations and the point of intersections denotes the points of equal height

Answer:

1) y = 3/5x + 8

2) Slope: 10

   y-intercept: -1/3

3) y = -1/2x - 1

Step-by-step explanation:

1) The equation you need to refer to for this problem is y = mx+b

m = slope (3/5 for this problem)

b = y-intercept(which is 8)

plug those numbers in and you get y = 3/5x + 8

2) look back at this equation: y = mx+b

10 is the slope and -1/3 is the y-intercept

3) This one is a bit more difficult as you need two other formulas to solve:

the slope formula, y1 - y2/x1 - x2, and the point-slope formula,

y - y1 = m(x - x1)

For this problem, you have the coordinates (4, -3) and (6, -4) which you would plug into the slope formula, like this:

-3 -(-4)/4 - 6 = -1/2

the numbers 1 and 2 in this formula refer to the first (x,y) value and the second. You subtract the two y values and the two x values, simplify, and you get your answer.

-1/2 is going to be the m, or slope, that you will use in the second formula, the point slope formula, y - y1 = m(x - x1)

To solve this you choose one of the original coordinates that you were given to plug into the y1 and x1, and plug -1/2, your slope, in for m:

(keep in mind, for this, I used (4,-3) but you can use either one)

y -(-3) = -1/2(x - 4)

To solve this you, first, distribute -1/2 to x and -4 inside the parentheses:

y -(-3) = -1/2x + 2

Then, on the other side, add the to negatives to get a positive 3:

y + 3 = -1/2x + 2

and subtract 3 from both sides:

y = -1/2x - 1

The required probability that the total number of spots showing is less than 7 is 9.26%

The probability of an event is found by considering all possibilities that follow the given condition. The probability value cannot exceed the interval [0,1].

Three six-sided dice are rolled at the same time.

It is asked to calculate the probability that the total number of spots showing is less than 7.

If the die is rolled, possible outcomes are as given below.

S: {1, 2, 3, 4, 5, 6}

Number of elements in sample space, n(S) = 6.

Probability of any specific outcome from S = 1/6

If the three dice are rolled together, the total number of elements in the sample space will be \((6^3)\)

Then, the probability of getting any of any specific outcome from this sample will be given by: \(\frac{1}{6^3} =\frac{1}{216}\)

Find the total possibilities for which the total of outcomes of all three dice is less than 7. It is possible when we get the following outcomes.

The minimum total that we get is 3 with outcomes (1,1,1) on three dice.

For a total of 3:

Possible outcomes: [1, 1, 1]

The number of possibilities \(A_1=1\)

For total 4:

Possible outcomes: [1,1,2], [1,2,1], [2, 1, 1]

Number of possibilities \(A_2=3\)

For a total of 5:

Possible outcomes:  [1,1,3], [1,3,1], [3, 1, 1],  [1,2,2], [2,2,1], [2, 1, 2]

The number of possibilities \(A_3=6\)

For a total of 6:

Possible outcomes :  [1,1,4], [1,4,1], [4, 1, 1],[1, 2, 3] ,[1,3,2],[2, 3, 1], [3,2,1], [3, 1, 2],[2,1,3], [2, ,2 ,2]

The number of possibilities : \(A_4=10\)

The number of possibilities for which the total number of spots showing is less than 7 is given by,

\(A_1+A_2+A_3+A_4\)

=> 1+ 3+ 6+ 10
