On a trip from Louisiana to Florida, your family wants to travel at least 420 miles in 8 hours of driving. Write and solve an inequality to find what your average speed must be.
The required the average speed must be at least 52.5 mph to travel 420 miles in 8 hours.
What is inequality?A difference between two values indicates whether one is smaller, larger, or simply not equal to the other. A B indicates that a and b are not equal. When a b, an is said to be less than b. A > B indicates that an is superior to b. These two constitute tight inequity.
According to question:Let the average speed of the trip "x" in miles per hour. To find out what the average speed must be, we need to write an inequality based on the given information and then solve it.
The formula for distance, speed, and time is:
distance = speed * time
So, the distance traveled can be written as:
distance = x * 8 hours
And the inequality based on the given information that the distance must be at least 420 miles is:
x * 8 ≥ 420
To solve for x, we need to divide both sides of the inequality by 8:
x ≥ 420 / 8
x ≥ 52.5
So, the average speed must be at least 52.5 mph to travel 420 miles in 8 hours.

What is an angle ?An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Interior angles:- The inner angle made by the intersection of two polygonal sides.
Exterior angles:- The outer angle made by the intersection of two polygonal sides.
The evidence in the proof that supports the statement that m/AOW = 45° is:
Statement 3: ZZOB ZXOA. This means that ZOB and ZOA are vertical angles, which means they are congruent.
Statement 4: m/XOA = 45°. This is the measure of ZOA, which is congruent to ZOB.
Statement 7: m/XOA + m/AOW = m/XOW. This is the angle addition postulate, which states that the sum of the measures of the angles in a triangle is 180°.
So, combining these pieces of evidence, we have:
m/XOA = 45° and m/XOA + m/AOW = m/XOW,
therefore m/AOW = m/XOW - m/XOA
= 90° - 45°
= 45°.

What is Rectangle?A plane shape, as opposed to a square, with four straight sides and four right angles, particularly one with uneven neighbouring sides.
The measurement of three-dimensional solids' surfaces the surfaces of three-dimensional solids, such as cubes, spheres, prisms, and pyramids, in
square or meter units, is known as Surface area.
Surface area of Square = side²
Surface area of Rectangle = Length x Breadth
Surface area of triangle = 1/2 × Base x Height
So,
Surface area of Square=
= 10² = 100m²
Surface area of Rectangle 1 =
= 11 x 9 = 99m²
Surface area of Rectangle 2 =
11 x 13.45 = 147.95m²
Surface area of Triangle =
= 1/2 x 10 x 9 = 45m²
So, Surface area of box = Surface area of Square + Surface area of
Rectangle 1+ Surface area of Rectangle 2 + Surface area of Triangle + Surface area of Triangle
= 100 + 99 + 147.95 + 45+ 45

Tangents to circles are lines that cross the circle at a single point. Point of tangency refers to the location where a tangent and a circle converge. The circle's radius, where the tangent crosses it, is perpendicular to the tangent. Any curved form can be considered a tangent. Tangent has an equation since it is a line. A line that touches a circle just once is said to be tangent to it. A point to circle can only have one tangent. The intersection of the tangent and the circle is known as the point of tangency.

You are going to use an incline plane to lift a heavy object to the top of a shelving unit with a height of 7 ft. The base of the incline plane is 11 ft from the shelving unit. What is the length of the incline plane?
Answer:
We can use the Pythagorean theorem to solve this problem. Let's call the length of the incline plane "L". We know that the height of the shelving unit is 7 ft and the base of the incline plane is 11 ft. The hypotenuse of the right triangle formed by the incline plane, the floor, and the shelving unit will be the length of the incline plane. Using the Pythagorean theorem:
L^2 = 11^2 + 7^2
L^2 = 121 + 49
L^2 = 170
L = sqrt(170)
So the length of the incline plane is approximately 13.04 feet.

How to calculate coefficient of variation?
Answer:
Step-by-step explanation:
The coefficient of variation (CV) is a measure of the relative variability of a set of data. It is calculated as the ratio of the standard deviation to the mean, expressed as a percentage. The formula for calculating the CV is as follows:
CV = (Standard Deviation / Mean) * 100%
Here's how to calculate the CV step by step:
Calculate the mean: To find the mean, add up all the data points and divide by the number of data points. This will give you the average value of the data set.
Calculate the standard deviation: The standard deviation is a measure of the variability of a set of data. To calculate it, subtract each data point from the mean and square the result. Then add up the squared deviations and divide by the number of data points minus one. Finally, take the square root of the result to obtain the standard deviation.
Calculate the CV: Finally, divide the standard deviation by the mean and multiply by 100% to obtain the CV.
The CV is a useful measure when comparing data sets with different units of measurement or when comparing the variability of data sets with different means. It gives an indication of the degree of variation in the data set relative to the mean, with higher CV values indicating a higher degree of variability.
It is important to note that the CV should not be used to compare data sets with very different means, as it can be misleading in such cases. In those cases, it is better to use the standard deviation or other measures of variability.

The standard deviation of the given data is 8.
Option B is the correct answer.
What is the standard deviation?To calculate the standard deviation of the given data, we can use the following formula:
σ = √ [Σ(xi - μ)² / N
where σ is the standard deviation, xi is each data point, μ is the mean of the data, and N is the total number of data points.
We have,
The mean of the data:
μ = (24 + 28 + 32 + 36 + 40 + 44 + 48) / 7
= 36
Now,
We can calculate the sum of squared differences from the mean.
Σ(xi - μ)²
= (24 - 36)² + (28 - 36)² + (32 - 36)² + (36 - 36)² + (40 - 36)² + (44 - 36)²
+ (48 - 36)²
= 144 + 64 + 16 + 0 + 16 + 64 + 144
= 448
And,
We can substitute these values into the formula for the standard deviation.
So,
σ = √ [Σ(xi - μ)² / N]
= √[448 / 7]
= 8.13

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given, A cubic polynomial f(x) = 2x³ - 11x² - 20x - 7.

Round your answer to the nearest thousandth.
Suggested: Needed in Decimal form (Regular outcome)
The probability that the Yankees scored fewer than 5 runs is 0.805.
What is probability?It is the chance of an event occurring from a total number of outcomes.
The formula for probability is:
Probability = Number of required events / Total number of outcomes.
We have,
We will use conditional probability.
P(A/B) = P(A∩B) / P(B)
The probability that the Yankees won a game.
= 0.59
This means,
The probability that the Yankees lost a game.
P(A) = 1 - 0.59 = 0.41
The probability that the Yankees scored 5 or more runs.
= 0.45
P(B) = The probability that the Yankees scored fewer than 5 runs.
So,
The probability that the Yankees lose and score fewer than 5 runs.
P(A ∩ B) = 0.33
Now,
The probability that the Yankees scored fewer than 5 runs.
P(B/A) =P(A∩B) / P(A)
So,
