Answer:

-5 =x

Step-by-step explanation:

15/x = -3

Multiply each side by x.

15 = -3x

Divide each side by -3.

15/-3 = x

-5 =x

Answer:

x = -5

Step-by-step explanation:

\(\sf \frac{15}{x} =-3\)

Multiply both sides by x.

15 = -3x

Answer:

15:2

Step-by-step explanation:

If you take 45 / 6 you will end up with 7.5

You can't have a ratio with a fraction. So to get a whole number you multiply 7.5 by 2 to get a full number. Therefore 15:2

One consequence of the popularity of the internet is that it is throughout to reduce television watching. Suppose that a random sample of 55 individuals who consider themselves to be avid Internet users results in a mean time of 2.10 hours watching television on a weekday. The  standard deviation  is  \(\sigma = 1.93\)

Required:

Determine the likelihood of obtaining a sample mean of 2.10 hours or less from a population whose mean is presumed to be 2.45 hours.

Answer:

The  likelihood is  \(P(X \le 2.10 ) = 0.08931\)

Step-by-step explanation:

From the question we are told that  

    The sample size is  \(n = 55\)

    The population mean is  \(\mu = 2.45 \ hours\)

    The random mean considered \(\= x = 2.10 \ hours\)

Generally the standard error of  mean is mathematically represented as

              \(\sigma _{\= x } = \frac{\sigma }{ \sqrt{n} }\)

=>           \(\sigma _{\= x } = \frac{1.93 }{ \sqrt{55} }\)

=>           \(\sigma _{\= x } = 0.2602\)

The  likelihood of obtaining a sample mean of 2.10 hours or less from a population whose mean is presumed to be 2.45 hours is mathematically represented as

               \(P(X \le 2.10 ) = 1 - P(X > 2.10 ) = 1 - P( \frac{X - \mu }{\sigma_{\= x }} > \frac{ 2.10 - 2.45}{ 0.2602} )\)

Generally    \(\frac{X - \mu }{\sigma_{\= x }} = Z(The \ standardized \ value \ of \ X )\)

               \(P(X \le 2.10 ) = 1 - P(X > 2.10 ) = 1 - P( Z > -1.345 )\)

From the z-table the value of

           \(P( Z > -1.345 ) = 0.91069\)

  So

        \(P(X \le 2.10 ) = 1 - P(X > 2.10 ) = 1 - 0.91069\)

         \(P(X \le 2.10 ) = 1 - P(X > 2.10 ) = 0.08931\)

        \(P(X \le 2.10 ) = 0.08931\)

Answer:

the answer is $153.69

After answering the presented question, we can conclude that So, the domain best answer from the choices provided is d. {1, 3, 5}.

A function's domain is the range of potential values that it can accept. These numbers indicate the x-values of a function like f. (x). The range of potential values that can be utilised with a function is known as its domain. The value that the method returns after inserting the x value belongs to this set. The formula for a function with y as the dependent variable and x as the independent variable is y = f. (x). When a single value of y can be successfully produced from a value of x, that value of x is said to be in the domain of the function.

The domain of a relation is the set of all first elements (or inputs) of the ordered pairs in the relation.

For the given relation {(3, 4), (1, 3), (1, 4), (5, 2)}, the first elements (or inputs) are 3, 1, 1, and 5. Therefore, the domain is {3, 1, 5}.

The fraction 13/7 lies between the fractions 6/6 and 6/7.

We have,

Between the fractions 6/6 and 6/7, there are infinitely many fractions.

To find a fraction that lies between these two fractions, we can take their average.

The fraction 6/6 simplifies to 1, and the fraction 6/7 cannot be simplified further.

To find the average, we add the two fractions and divide the sum by 2:

(6/6 + 6/7) / 2

To add the fractions, we need a common denominator, which is the least common multiple (LCM) of 6 and 7, which is 42.

Converting the fractions to have a common denominator:

(6/6) x (7/7) + (6/7) x (6/6) / 2

Simplifying the expression:

(42/42 + 36/42) / 2

Combining the numerators:

(78/42) / 2

Dividing:

78/42 = 13/7

Answer:

Step-by-step explanation:

To check whether the given credit card number is valid or not, we need to apply the Luhn algorithm or the mod-10 algorithm. The Luhn algorithm works by adding up all the digits in the credit card number and checking if the sum is divisible by 10 or not. If it is, then the credit card number is considered valid, otherwise, it is invalid.

Let's apply the Luhn algorithm to the given credit card number:

Step 1: Starting from the rightmost digit, double every second digit

| 5 | 4 | 2 | 4 | 9 | 8 | 1 | 3 | 2 | 7 | 2 | 0 | 0 | 0 | 8 | 5 |

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

| | 8 | | 8 | | 16| | 6 | | 14| | 0 | | 0 | | 10|

Step 2: If the doubled value is greater than 9, add the digits of the result

| 5 | 4 | 2 | 4 | 9 | 8 | 1 | 3 | 2 | 7 | 2 | 0 | 0 | 0 | 8 | 5 |

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

| | 8 | | 8 | | 7 | | 6 | | 5 | | 0 | | 0 | | 1 |

Step 3: Add up all the digits in the credit card number, including the check digit

5 + 4 + 2 + 4 + 9 + 8 + 1 + 3 + 2 + 7 + 2 + 0 + 0 + 0 + 8 + 5 + 1 = 61

Step 4: If the sum is divisible by 10, then the credit card number is valid, otherwise, it is invalid.

61 is not divisible by 10, therefore the given credit card number is invalid.

Hence, it can be concluded that 5424 9813 2720 0085 is an invalid MASTERCARD credit card number.

d) Adjacent angles share a side, typically between the two angles. A linear pair of angles will be adjacent angles.

  ∠BAD and ∠CAD are adjacent angles

e) In order to properly name a pair of vertical angles, we need to be able to name two sets of opposite rays that share end points. Opposite rays emanate from points C and D, but no named points are seen outboard of those intersections. If we use 'm' as the name of a point on line m, then we can say a pair of vertical angles is ...

  CDm and BDA are two vertically opposite angles

Answer:

A. 8

Step-by-step explanation:

32 divided by 4 = 8

The answer is a. 8 in.

Since the width of the rectangle is 4 inches (in) and the area of the rectangle is 32 in², we need to find the length of the rectangle.

We know that the area of a rectangle with length, L and width, W is A = LW.

Since we need to find the length of the rectangle, we make the length, L subject of the formula.

Since A = LW,

L = A/W

Given that A = 32 in² and W = 4 in

Substituting the values of the variables into the equation, we have

L = 32 in²/4 in

L = 8 in

So, the length of the rectangle is 8 in

The only information of h(x) that we have is the given graph.

To find the value of x, we need to go to the vertical axis and find y = 4, then we move horizontally to the left until we meet the curve.

That intersection will give the value of x for which h(x) = 4.

Doing that, we conclude that h(x) = 4 when x = 0 (on the vertical axis).

Now we want to find h(-2), and we can do that using the graph.

The Expression x^2 - 6x + 9 when x = 2 + i   is -2i

To evaluate the expression x^2 - 6x + 9 when x = 2 + i, we substitute the value of x into the expression:

(2 + i)^2 - 6(2 + i) + 9

Simplifying the first term, we get:

(2 + i)^2 = 2^2 + 2(2)(i) + i^2 = 4 + 4i + i^2

Since i^2 = -1, we can substitute that in and simplify further:

(2 + i)^2 = 4 + 4i - 1 = 3 + 4i

Now we substitute this into the original expression:

(2 + i)^2 - 6(2 + i) + 9 = (3 + 4i) - 6(2 + i) + 9

Simplifying further, we get:

= 3 + 4i - 12 - 6i + 9

= 0 - 2i

= -2i

Therefore, the value of x^2 - 6x + 9 when x = 2 + i is -2i.
