The amount that the cell phone owner will pay for the overages is $14.91.

The overage is the difference between the actual usage in minutes and the estimated usage.

For instance, if the plan estimates that the phone usage per year would be 4,000 minutes, but the plan holder uses 4,010 minutes, the extra 10 minutes are regarded as overages.

The opposite of overages is underages.  If underages are part of the phone plan, the plan holder will be refunded accordingly.

Usually, overages attract a variable plan rate per minute.

Fixed charge per month = $35.98

Utilities tax APR = 6.5%

Overages = 40 minutes

Rate per overage minute = $0.35

The total charge for overage = $14 ($0.35 x 40)

Interest on the overages = $0.91 ($14 x 6.5%)

Total payment for the overages = $14.91 ($14 + $0.91)

Thus, for going over the plan by 40 minutes at $0.35 plus an APR of 6.5%, you will pay $14.91 for the overages.

The number of pounds eaten by each cow each day = 12 pounds.

Therefore if one cow eat 12 pounds a day then 24 cows=

12 × 24 = 288 pounds a day

Therefore if,

The larger angle in the straight line is 101°.

What is straight line angle?

   A straight angle in mathematics is one with a sine angle of 180 degrees. Due to the fact that it resembles a straight line, it is called straight. Those angles that make a straight line are known as straight angle pairs. Each angle in this pair adds up to 180 degrees, regardless of how many angles make up the pair. A straight angle in geometry is one that is equal to 180 degrees. It looks like a straight line, hence the name "straight angle." It is an angle, then, whose sides are in the same straight line but opposite to the vertex.

We know that , In straight line angle at any point is 180°.

Here,

=> (14x+3)°+(11x+2)°=180°

=>14x+3+11x+2=180

=>25x+5=150

=>25x=180-5=175

=> x = 175/25 = 7.

Then , 14(7)+3=101° and 11(7)+2=79°.

Hence the larger angle is 101°.

The binomial distribution is used when there is a fixed number n of trials, with each trial having only two possible outcomes, success or failure, and trials are independent, that is, the probability of success on any trial is the same.

For item b, the parameter p is obtained as follows:

The sum of all the probabilities is of one, hence:

3.5p = 1.

p = 1/3.5

p = 0.2857.

For item i, the probability is obtained as follows:

Hence:

p = (1 - 0.2857)^5 x 0.2857 = 0.0531 = 5.31%.

Step-by-step explanation:

The domain of given graph is [-8,8].

The domain of a function is a set of all x values i.e. the numbers for which function is defined. All of a function's x-values, or inputs, make up the domain, and all of a function's y-values, or outputs, make up the range. When viewing a graph, the whole range of numbers from left to right comprise the domain.

As seen from the graph graph is limited from -8 to +8 that means the domain of the graph is [-8,8].

Step-by-step explanation:

Given various triangle descriptions, you want to know which one describes more than one triangle.

The angles and sides of a triangle satisfy a few different relations:

A. Two sides and the included angle can be used with the Law of Cosines to find the length of the third side. That is, a single triangle is created by these measurements.

B. Sides measuring 4, 8, and 15 do not satisfy the triangle inequality, so no triangle is created by these measurements.

C. Sides measuring 6, 8, and 10 satisfy the triangle inequality, so will create a single triangle. (That triangle is a right triangle.)

D. The given angles total 180°, so could be the angle measures of any number of triangles. At least one side length must be specified in order to completely define a single triangle. These measures create more than one triangle.

The width of the rectangle should be 8 units.

Calculation of the width:

Since The width of a rectangle is 1 units less than the length. The area of the rectangle is 72 units.

Here we know that

The values of the vertical motion modelled by the quadratic function, h(t) = -16·t² + 54·t + 3 of the object are;

The maximum height reached is approximately 48.6 units

The time of flight is approximately 3.4 seconds

A quadratic function is a polynomial of the form y = a·x² + b·x + c, where the value of a is larger than or lesser than 0

First part;

The function, for the vertical motion, h(t) = -16·t² + 54·t + 3, is a quadratic function;

The maximum height is found by using the equation that gives the value of x at the maximum value, which is presented as follows;

At the maximum point, [tex]x = \dfrac{-b}{2\cdot a}[/tex]

From the equation, a = -16, b = 54, c = 3, and x = t, which gives;

[tex]t = \dfrac{-54}{2\times (-16)} = 1.6875[/tex]

The maximum height is therefore;

h(1.6875) = -16 × 1.6875² + 54 × 1.6875 + 3 = 48.6

The time the object is in the air is found using the equation;

h(t) = 0 = -16·t² + 54·t + 3

Using the quadratic formula, [tex]x= \dfrac{-b\pm \sqrt{b^2 - 4\cdot a \cdot c} }{2 \cdot a}[/tex], we have;

[tex]t= \dfrac{-54\pm \sqrt{54^2 - 4\times (-16)\times 3} }{2 \times (-16)}=\dfrac{27\pm \sqrt{777} }{16}[/tex]

The time of flight is therefore;

[tex]t=\dfrac{27+ \sqrt{777} }{16}\approx 3.4[/tex]

By finding all the probabilities we will see that the event that is least likely to occur is the one in option D.

A) The probability is computed as the quotient between the outcomes that meet the conditions for the event and the total number of outcomes.

Here the outcomes are {1, 2, 3, 4, 5, 6, 7, 8}

The outcomes that meet the condition (less than or equal to 6) are:

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

So 6 outcomes out of 8 meet the condition, the probability here is:

a = 6/8 = 3/4 = 0.75

B) The probability here is 1, as all the outcomes meet the condition of "landing in some color"

The probability of observing an 85°F temperature or higher in Los Angeles during a randomly chosen day in June is 0.266.

We are given information about the temperatures in Los Angeles for the month of June. The average daily high temperature in June in LA is 80°F. The standard deviation in the temperature values is 8°F. The temperatures in June closely followed a normal distribution. We need to find the probability of observing an 85°F temperature or higher in Los Angeles during a randomly chosen day in June. Let the mean, standard deviation, value, z-score, and probability be represented by the variables M, S, X, Z, and P. First of all, we will find the z-score for the given temperature value.

Z = (X - M)/S = (85 - 80)/8 = 5/8 = 0.625

An explicit formula of the form an = bn + c to model this situation.

When n = 10,

= 41,900 + 1100n
