Choose the equation that represents the graph below:



A) Y= -2x-6

B) Y= 2/3x+6

C) Y= -2/3x+6

D) Y= 2x+6

Answer:

1/2 or 50% or 3/6

Step-by-step explanation:

There are 6 numbers on a die.

If the die is rolled 1 time and you want a number 4 or greater that leaves 4, 5, and 6.

6 - 3 = 3

3 + 3 = 6

therefore, 1/2 a chance of getting one of those numbers.

Answer:

it's 3/6

Step-by-step explanation:

because there are 3 numbers greater, equal than 4(4,5,6) and there in total are 6 sides in a die so the probability is 3/6

Answer:

6/1 is equal to 6.

Step-by-step explanation:

Any number divided by 1 results in the same number. So, 6/1 = 6.

Value of other fractions:
1/6 = 0.166
6/6 = 1
6/10 = 0.6
6/60 = 0.1

Step-by-step explanation:

The interpretation states that if Jimmy rolls the die multiple times, he has a 67% chance of obtaining a result that falls into the set of numbers:

2, 4, 5, or 6. B.

The accurate interpretation of the given probability, which is approximately 67%, is as follows:

"He has a 67% chance of getting a 2, 4, 5, or 6."

This interpretation aligns with the probability calculation provided in the question.

The probability of rolling a die and getting a number greater than or equal to five (5 or 6) or getting an even number (2, 4, or 6) is 2/3 or approximately 67%.

This means that in the long run, out of many rolls, approximately 67% of the outcomes would be one of these four numbers.

The other options provided do not accurately represent the probability calculation or its interpretation.

They introduce specific numbers of rolls or limited outcomes that are not consistent with the given probability.

The accurate interpretation reflects the inclusive nature of the probability and correctly identifies the set of numbers that Jimmy has a 67% chance of obtaining.

Option (A) difference of the means is significant because the rerandomizations show that it is within the range of what likely happens by chance is the correct option.

"A dot plot is used to represent any data in the form of dots or small circles. It is similar to a simplified histogram or a bar graph as the height of the bar formed with dots represents the numerical value of each variable. Dot plots are used to represent small amounts of data".

For the given situation,

A randomized study shows the comparison of two drugs that are designed to lower a person's triglyceride level.

Drug A decreased their triglyceride level by a mean of 69.

Drug B decreased their triglyceride level by a mean of 45.

Mean difference = \(69-45\)

On Julie's door, the images will span 210 square inches.

As Julie printed six images, the total space that the images cover is:

6 x 35 square inches = 210 square inches

Inches are measured as 1/36 of a yard in both British Imperial and American Customary measurement systems. According to some sources, the term "inch" comes from the Old English "ince" or "ynce," which in turn is said to have originated from the Roman "uncia" unit.

The name of another English unit, the ounce, is derived from the Roman word uncia. According to legend, King David I of Scotland defined the old English word "ynce" as the width of a man's thumb at the base of the nail in the year or thereabouts 1150 AD.

From the question:

Six images total, each measuring 5 by 7 inches, were printed by Julie. We must first calculate the area of each image in order to add up the overall area that these photographs cover.

One image's area is as follows:

5 inches x 7 inches = 35 square inches

As Julie printed six images, the total space that the images cover is:

6 x 35 square inches = 210 square inches

Consequently, 210 square inches of Julie's door will be covered by the images.

Answer:

\(Range = 85\)

\(\sigma = 28.71\)

\(Interval = [666.78, 781.62]\)

Step-by-step explanation:

Given

The data for 25 undergraduates

Solving (a): Range and Standard deviation

The range is:

\(Range = Highest - Least\)

From the dataset:

\(Highest = 772\)

\(Least = 687\)

So:

\(Range = Highest - Least\)

\(Range = 772-687\)

\(Range = 85\)

The standard deviation is:

\(\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}\)

First, calculate the mean

\(\bar x = \frac{769 +691 +............+715}{25}\)

\(\bar x = \frac{18105}{25}\)

\(\bar x = 724.2\)

So, the standard deviation is:

\(\sigma = \sqrt{\frac{(769-724.2)^2 +(691-724.2)^2 +(699-724.2)^2 +(730-724.2)^2 +............+(715-724.2)^2}{25}}\)

\(\sigma = \sqrt{\frac{20604}{25}}\)

\(\sigma = \sqrt{824.16}\)

\(\sigma = 28.71\)

Solving (b): The interval of the 95% of the observation.

Using the emperical rule, we have:

\(Interval = [\bar x - 2*\sigma, \bar x+ 2*\sigma]\)

\(Interval = [724.2 - 2*28.71, 724.2 + 2*28.71]\)

\(Interval = [666.78, 781.62]\)

Option B is correct.

64x³ + 27 = (4x + 3) (16x² - 12x + 9)

Explanation

We are told to factorize

64x³ + 27

To do this, we use the factorization of (x³ + y³) as a guide. First of,

(x + y)³ = (x + y) (x + y)² = (x + y) (x² + 2xy + y²)

(x + y)³ = x³ + y³ + 3x²y + 3xy²

So, we can write

x³ + y³ = (x + y)³ - 3x²y - 3xy² = (x + y)³ - 3xy(x + y)

= (x + y) [(x + y)² - 3xy]

= (x + y) (x² + y² + 2xy - 3xy)

= (x + y) (x² - xy + y²)

So, comparing (64x³ + 27) with (x³ + y³), we can see that

64x³ = (4x)³

27 = (3)³

(64x³ + 27) = (4x)³ + 3³

x³ + y³ = (x + y) (x² - xy + y²)

(4x)³ + 3³ = (4x + 3) [(4x)² - (4x × 3) + 3²]

= (4x + 3) (16x² - 12x + 9)

Answer: 2a < 2b

Step-by-step explanation:

We are given a statement:

a < b and b < c, then 2a ____ 2b

We can use simple numbers that make the statement true.

Where,

a = 2

b = 3

c = 4

Now lets plug it in.

2 < 3 and 3 < 4, then 2(2) ____ 2(3)

and lets simplify:

2 < 3 and 3 < 4, then 4 ____ 6

We can see that 4 is less than 6,

so as a is less than b, 2a is less than 2b.

The only thing changing is the coefficient being multiplied by the variables a and b.

Option (b) is the correct answer: Perpendicular segments.

Perpendicular rays, perpendicular segments, perpendicular lines, and parallel lines are important concepts in geometry that describe the relationship between lines and line segments.

1. Perpendicular Rays: Perpendicular rays are two rays that intersect at point and form a right angle (90 degrees) at the point of intersection. The rays extend indefinitely in opposite directions from the point of intersection.

2. Perpendicular Segments: Perpendicular segments are line segments that intersect at a right angle. They share a common endpoint but do not extend indefinitely like rays. The right angle is formed at the point of intersection.

3. Perpendicular Lines: Perpendicular lines are lines that intersect at a right angle. They continue indefinitely in opposite directions and form four right angles at the point of intersection. Perpendicular lines are often denoted by a symbol ⊥.

4. Parallel Lines: Parallel lines are lines that never intersect. They remain equidistant from each other at all points. Parallel lines have the same slope and do not converge or diverge. In Euclidean geometry, parallel lines are denoted by a double vertical line symbol (||).

Understanding these concepts is fundamental in geometry as they help define angles, shapes, and spatial relationships. The properties of perpendicular and parallel lines play a crucial role in various geometric theorems and applications.

Solution :

The Boolean expression A >= B is equivalent to  !(A < B) (option A)

To simplify a Boolean expression, use De Morgan's Law.

De Morgan's Law is used to simplify or find the equivalent of a negation of compound expressions.

The principle is:

NOT (A AND B) is equivalent to (NOT A) OR (NOT B)

NOT (A OR B) is equivalent to (NOT A) AND (NOT B)

When the expression involves >, <, = signs, then to simplify the expression, move the not and flip the sign.

! is the symbol of negation or NOT.

Hence,

! (>) becomes <=

! (<) becomes >=

Here are some examples:

!(A > B) is equivalent to (A <= B)

!(A <= B) is equivalent to (A > B)

!(A >= B) is equivalent to (A < B)

!(A == B) is equivalent to (A != B)

!(A != B) is equivalent to (A == B)

!(A < B) is equivalent to (A >= B)

From the above list we can conclude that A >= B is equivalent to !(A < B) (option A)

Answer:

The warranty the company should use is of 57,520 mile.

Step-by-step explanation:

Let X denote the tread life of a particular brand of tire.

It is provided that,  \(X\sim N(60,000, 1600^{2})\).

Also provided that the company wants 94% of the tires to outlast the warranty.

Let x denote the warranty .

That is, P (X > x) = 0.94.

⇒ P (X < x) = 0.06

⇒ P (Z < z) = 0.06

The corresponding value of z is -1.55.

*Use a z-table.

Compute the value of x as follows:

\(z=\frac{X-\mu}{\sigma}\\\\-1.55=\frac{x-60000}{1600}\\\\x=60000-(1.55\times 1600)\\\\x=57520\)

Thus, the warranty the company should use is of 57,520 mile.
