The probability that a tire of this brand will last longer than 58,000 miles is  0.8413 or 84.13%.

Given in the question that the tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000 miles and a standard deviation of 2000 miles.

We have to calculate the probability that a particular tire of this brand which will last longer than 58,000 miles.

The standard normal variable corresponding to the given tire's tread life being longer than 58,000 miles can be calculated using the z-score formula:

The formula for computing a z-score is =(DataValue-Mean)/StDev

Therefore , we can write z = (58,000 - 60,000) / 2000

Hence, z = -1

Next, we can use a standard normal table to find the probability that a standard normal variable will be less than -1:

P(Z < -1) = 0.1587

Hence P = 1 - 0.1587

            P = 0.8413

The volume of one carton of strawberries is 200 in³.

The volume of all of the cartons of strawberries is 6,000 in³.

The volume of each carton can be determined by multiplying the length, width and height together.

Volume = length x width x height

10 x 4 x 5 = 200 in³

The volume of all the boxes of strawberries can be determined by multiplying the number of cartons by the volume of one carton.

Volume of the 30 cartons of strawberries = 200 in³ x 30 = 6,000 in³

Answer: 900

Step-by-step explanation:

The Interior Angle formula is (n-2)x180. So you take 7 minus 2 times 180 and that gives you 900

The value of the trigonometric function is -

sin(θ) = 21 / 29,

cos(θ) = 20/29,

csc(θ) = 29/21,

sec(θ) = 29/20,

cot(θ) = 20/21.

In a nutshell, trigonometric functions, also referred to as circular functions, are the functions of a triangle's angle. This suggests that these trig functions provide the relationship between a triangle's angles and sides. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.

Given that,

tan (θ) = - 21 / 20

We can infer from the value that the triangle's two legs are 21 and 20, respectively.

Using the Pythagorean theorem, we can:

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex](21)^{2} + (20)^{2} = c^{2}[/tex]

441 + 400 =[tex]c^{2}[/tex]

c = 29

The value of :

sin(θ) = 21 / 29

cos(θ) = 20/29

csc(θ) = 29/21

sec(θ) = 29/20

cot(θ) = 20/21

Hence, the value of the trigonometric function is

sin(θ) = 21 / 29,

cos(θ) = 20/29,

csc(θ) = 29/21,

sec(θ) = 29/20,

cot(θ) = 20/21.

Answer:  Richard is 22 and Teo is 9

Step-by-step explanation:

The cost when the two options are the same is equal to $60.

Based on the information provided above, Rhianna's Tees charges a $20 setup fee and then to buy the shirts for $8 each. The total cost, y, can be represented by this equation:

y = 8x + 20    ....equation 1.

where:

x represents the number of shirts.

For the second option, the total cost of the shirt can be represented by this equation:

y = 6x + 30        ....equation 2.

By equating equation 1 and equation 2, we have the following:

8x + 20 = 6x + 30

8x - 6x = 30 - 20

2x = 10

x = 5

Now, we can determine the cost as follows;

y = 8x + 20

y = 8(5) + 20

y = 40 + 20

y = $60.

In a residual plot, the residuals are plotted against the predictor variable. Ideally, the residuals should be randomly scattered around zero, without any patterns or trends.

If there is a pattern, it suggests that the linear model is not an adequate representation of the data and a more complex model may be necessary.

In this case, the residual scatter plot shows that the residuals are randomly scattered around zero, which suggests that a linear model is appropriate for summarizing the relationship between the predictor and response variables. This means that a straight line can be used to approximate the relationship and make predictions based on the data.

According to this information, investments with 4.2, 1.3 and 2.8 interest have a profit of more than $100. On the other hand, investments with interest of 0.75 and 5.2 have a profit of less than $100.

To calculate the profit of these investments we must carry out the following procedure:

1. We must divide the interest in 100

2. We must multiply the interest by the total value of the investment ($1500).

3. We must multiply the result by the number of years of the investment.

4. We must classify the result as less than or greater than $100.

According to the above, investments with 4.2, 1.3 and 2.8 interest have a profit of more than $100. On the other hand, investments with interest of 0.75 and 5.2 have a profit of less than $100.

An arithmetic sequence is a sequence of numbers where the difference between any two consecutive terms is always the same. In this case, the common difference is 3, so every term is 3 more than the previous term.

The [tex]$n^{th}$[/tex] term in the arithmetic sequence can be found using

[tex]$a_n = a_1 + (n - 1)d$[/tex]

where $a_1$ is the first term (2 in this case), $d$ is the common difference (3 in this case), and $n$ is the term number.

To find the page number that $11{,}111$ appears on, we need to find the term number that corresponds to this value:

[tex]$11{,}111 = 2 + (n - 1) \cdot 3$[/tex]

Solving for $n$, we have:

$11{,}109 = 3n - 1$

$3n = 11{,}110$

$n = 37{,}037$

The water's height at 8:30 PM is approximately 0.69 feet.

As per the data given in the question,

We have the equation,

depth = 4 * sin (0.5 * t)

where t is the number of hours after midnight.

As we need to find the depth of the water at 8:30 PM,

For finding the value of the depth at 8:30 PM we need to first convert 8:30 PM to the number of hours after midnight.

8:30 PM = 20.5 hours after midnight

So, substituting t = 20.5 into the equation,

we will get it as:

depth = 4 * sin (0.5 * 20.5)

depth = 4 * sin (10.25)

depth = 4 * 0.1736481776669303

The solution to the given inequality  [tex]-5f + 6 > 10f - 10[/tex] is [tex]f < 16/15[/tex].

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The inequality is given in the question, as follows:

[tex]-5f + 6 > 10f - 10[/tex]

To solve the inequality [tex]-5f + 6 > 10f - 10[/tex], we need to isolate the variable [tex]f[/tex] on one side of the inequality.

We will first subtract 6 from both sides to isolate the [tex]-5f[/tex] term:

[tex]-5f + 6 - 6 > 10f - 10 - 6[/tex]

Simplifying the left side:

[tex]-5f > 10f - 16[/tex]

Next, we will subtract [tex]4f[/tex] from both sides to isolate the [tex]-5f[/tex] term on the left side:

[tex]-5f - 10f > 10f - 10f - 16\\-15f > -16[/tex]

The probability that candidate B is going to win the election is 2.

The probability of candidate A winning the election is 0.5, the probability of candidate B winning the election is 2, the probability of candidate C winning the election is 1/3 and the probability of candidate D winning the election is 2/3.

Therefore, the candidate most likely to win the election is candidate B, and the probability that they are going to win is 2. This can be calculated using the formula for probability, which states that the probability of an event occurring is the number of favourable outcomes divided by the total number of outcomes. In this case, the number of favourable outcomes is 1 and the total number of outcomes is 3, so the probability of candidate B winning is 1/3.
