The amount that you have to pay for the time is $300.

From the information, the person is buying some television time and the station tells you that they reach 120,000 people and they quote you $2.50 CPM

The cost will be:

= Total people × Cost per thousand

= 120000/1000 × $2.50

= 120 × $2.50

= $300

The value of the first angle is 18

The value of the second angle is 9

The value of the third angle is 153

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Let the second angle be = x ____(1)

The measure of the first angle of this triangle is double the measure of the second angle.

This means,

First angle = 2x _____(1)

The measure of the third angle is 117​° greater than double the measure of the first angle.

This means,

Third angle = 117 + 2(2x) = 117 + 4x _____(3)

From (1) (2) and (3) we get,

x + 2x + 117 + 4x = 180

7x + 117 = 180

7x = 180 - 117

7x = 63

x = 9

The value of first angle is 2x = 2 x 9 = 18

The value of the second angle is x = 9

The value of third angle is 117 + 4x = 117 + 4 x 9 = 117 + 36 = 153

Thus,

The value of the first angle is 18

The value of the second angle is 9

The value of the third angle is 153

The two points that could be used to plot the graph of the function (0, -0.4) and (-0.874, 0)

In this question, we have been given a function f(x) = (3x³ + 2)/(x^2-5).

We need to plot the graph of the function.

We find some coordinates of point on the graph of function.

For x = 0,

f(0) =  (30³ + 2)/(0^2-5)

f(0) = 2/(-5)

f(0) = -0.4

For f(x) = 0,

0 = (3x³ + 2)/(x^2-5)

(3x³ + 2) = 0

3x³ = -2

x = -0.874

for x = 1,

f(1) = (3(1)³ + 2)/(1^2-5)

f(1) = 5/(1 - 5)

f(1) = 5/(-4)

f(1) = -1.25

The graph of function f(x) = (3x³ + 2)/(x2-5) is as shown below.

The domain of the function is real numbers.. The value is x-1 = is a real number

The domain of a function is the set of values that we are allowed to enter into our function. This set consists of the x values for a function like f. (x). The set of values that a function can accept as input is known as its range. Once we enter an x value, the function returns this list of values.

Think about the equation y = f(x), where x and y are the independent and dependent variables. If a value for x successfully enables the creation of a single value y using another value for x, it is said to be in the domain of the function f.

Answer:

The correct answer is: C

The measure of angle A is 53.6° if angle A and angle B are supplementary angles.

According to the question,

We have the following information:

Angles A and B are supplementary.

Measure of angle B = 126.4°

We know that when two angles are supplementary then it means that the sum of these angles will be 180°.

So, we have the following expression:

Angle A + angle B = 180

Angle A+126.4 = 180

Subtracting 126.4 from both the sides of the equation:

Angle A = 180-126.4

Angle A = 53.6°

Hence, the measure of angle A is 53.6° if angle A and angle B are supplementary.

Step-by-step explanation:

secx - 2=0

secx= 2

x= π/3

that's it

The x-values that satisfy the equation Sec(x) - 2 = 0 are x = π/3 and x = 5π/3.

To verify the given equation, we need to find the value(s) of x that satisfy the equation Sec(x) - 2 = 0.

Sec(x) represents the secant function, which is the reciprocal of the cosine function.

The equation can be rewritten as follows:

Sec(x) = 2

To find the solutions, we can take the reciprocal of both sides:

1 / Cos(x) = 2

Next, we can invert the equation to get the cosine function alone:

Cos(x) = 1/2

The cosine function has a value of 1/2 at two specific angles in the interval [0, 2π]: π/3 and 5π/3.

These angles correspond to the inverse cosine function (arccos), so we have:

x = arccos(1/2) = π/3 or x = arccos(1/2) + 2π = 5π/3

Therefore, the x-values that satisfy the equation Sec(x) - 2 = 0 are x = π/3 and x = 5π/3.

For the 95% confidence interval for the number of toys that are from China in a random sample of 210 toys, using the z-distribution, we have that:

a) The critical value would be of z = 1.96.

b) The standard error is of: 0.0316

c) The margin of error is of: 6%.

d) The expected number of toys in the sample is of: 147.

e) The lower limit of the interval is of: 64%.

f) The upper limit of the interval is of: 76%.

A confidence interval of proportions has the bounds obtained by the rule presented below as follows:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

The variables used to calculated these bounds are listed as follows:

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The estimate and the sample size for this problem are given as follows:

[tex]\pi = 0.7, n = 210[/tex]

Hence the expected number of toys in random sample of 210 toys is of:

0.7 x 210 = 147.

The standard error is calculated as follows:

[tex]s = \sqrt{\frac{\pi(1-\pi)}{n}} = \sqrt{\frac{0.7(0.3)}{210}} = 0.0316[/tex]

The margin of error is the multiplication of the critical value and of the standard error, hence:

M = 1.96 x 0.0316 = 0.06 = 6%.

The bounds of the interval are the estimate plus/minus the margin of error, hence they are given as follows:

a) The piece of information not required to compute the bill after tax and tip is the cost of the item purchased by the customer.

b) The total bill paid by the restaurant customer is $22.97.

The total bill the restaurant customer paid represents 100% of $1.30 plus the tip.

Proportionately, the amount can be computed using the percentage of the tip to equate the dollar amount.

The result is the cost of the item plus tax.  Then, the total bill includes the cost, tax, and tip.

Tip left by customer = $1.30

Sales tax = 6%

Cost + tax = x

Tip = 6% of x

x = $21.67 ($1.30 ÷ 6%)

The total bill paid is $22.97 ($21.67 + $1.30).

Median is the middle number of a data set.

You need to first start off with listing the shoe sizes in numerical order:

5, 5.5, 6, 6.5, 6.5, 7, 7.5, 8, 8, 8.5, 9.5

You have a total of 11 numbers in the set, so you can choose the sixth number in the set, which is 7.

So, 7 is the median number.

The median of current data is 6.5 while by adding 9.5 to the data group the median changes to 6.75.

Mode is the highest frequency number while the median is the middle value of a data set after writing in either an increasing or decreasing manner.

For example;

Set { 1,2,2,3,4,5,6} here mode is 2 and median is 3.

As per the given data,

5.5, 6, 7, 8.5 6.5,6.5, 8, 7.5, 8 5

Write the above data in increasing order,

5,5.5,6,6.5,6.5,7,7.5,8,8.5

The median is the middle value thus, 6.5 will be the median.

Now let's add 9.5 to the data group,

5,5.5,6,6.5,6.5,7,7.5,8,8.5,9.5

Now we have two middle values 6.5 and 7

Median = (6.5 + 7)/2 = 6.75

Hence "The median of current data is 6.5 while by adding 9.5 to the data group the median changes to 6.75".
