Answer:

2  2/3

Step-by-step explanation:

I'm going to change it to a multiplication problem by flipping the fraction after the division sign: 4/6  *    12/3

I'm going to reduce the fractions:  2/3   *  4

I'm going to write 4 as 4/1           : 2/3   * 4/1

Multiply straight across on top and straight across on bottom:   8/3

How many times does 3 go into 8:    2

The remainder of that is 2

So 8/3 can be written as    2  2/3  which really just means 2+2/3

Answer:

[tex] 2 \frac{2}{3} [/tex]

Step-by-step explanation:

To divide by a fraction multiply by the reciprocal of that fraction (flip the fraction you are dividing by and multiply)

[tex] \frac{4}{6} \times \frac{12}{3} [/tex]

Reduce the fractions and multiply:

[tex] \frac{4}{1} \times \frac{2}{3} = \frac{4 \times 2}{1 \times 3} = \frac{8}{3} [/tex]

8/3 equals 2 2/3.

Konichiwa~! My name is Zalgo and I am here to be of assistance to you today. The answer to your question would be Answer Choice 1/A;5/2>3/2. The reason it is the 1st answer choice is because 5/2 turned into a decimal is 2.5, but 3/2 turned into a decimal is 1.5, so since 2.5 is greater than 1.5, that would be the evidence that the 1st answer choice is correct!

Answer:

x-axis only.

Step-by-step explanation:

2x = 5y2 - 3

Convert to vertex form:

x = 5/2 y^2 - 3/2

This is a parabola  with axis of symmetry  y = 0. The vertex is at (-3/2, 0) and it opens to the right.

The axis of symmetry is the x-axis ( y = 0).

The equation 2x = 5y2 - 3 is only symmetric with respect to the x-axis but not the y-axis or the origin.

To test an equation for symmetry with respect to the x-axis, you would replace 'y' with '-y' and see if the equation remains the same. For symmetry with respect to the y-axis, you'd replace 'x' with '-x'. For origin symmetry, you would replace 'x' with '-x' and 'y' with '-y'

Applying this to your equation, 2x = 5y2 - 3:

The ten-thousandths place is the fifth digit to the left of the decimal point, which is a 7 in this case.

The next number to the right of the 7 is a 4, which is 4 or less, so you don't need to round up the 7.  This means we can just replace the 4 and everything to the right of it with 0s.

If the 4 were 5 or more instead, you would turn the 7 into an 8 and then turn everything after it into 0s.

Answer:

c. and second one is B

Step-by-step explanation:

Answer:

Events D and C are mutually exclusive.

Step-by-step explanation:

Two events D and C are mutually exclusive if

[tex]Pr(D\cup C)=Pr(D)+Pr(C)[/tex]

Find these probabilities. In a standard deck of 52 playing cards there are 13 diamond cards and 13 club cards.

The probabilty of chosing diamond is

[tex]Pr(D)=\dfrac{13}{52}=\dfrac{1}{4}[/tex]

The probabilty of chosing club is

[tex]Pr(C)=\dfrac{13}{52}=\dfrac{1}{4}[/tex]

The probabilty of chosing diamond or club is

[tex]Pr(D\cup C)=\dfrac{13+13}{52}=\dfrac{1}{2}[/tex]

Since

[tex]\dfrac{1}{2}=\dfrac{1}{4}+\dfrac{1}{4},[/tex]

events D and C are mutually exclusive.

Final answer:

In the context of a standard deck of 52 playing cards, the events representing diamonds (D) and clubs (C) are mutually exclusive events because a single card cannot be both a diamond and a club at the same time.

Explanation:

The question asks about the concept of mutually exclusive events in probability, using the context of a standard deck of playing cards. In a standard deck, there are four suits: spades, hearts, diamonds, and clubs. Diamonds (D) and clubs (C) are two different suits of cards, and so they are mutually exclusive events because the same card cannot be both a diamond and a club at the same time.

In reference to a standard deck of 52 cards which contains clubs, diamonds, hearts, and spades, each suit has 13 cards - A (ace), 2 through 10, J (jack), Q (queen), and K (king). Therefore, seeing as how a card from a deck cannot belong to two different suits, D and C are mutually exclusive events; there is no overlap between these two groups of cards.

In a normal distribution, 99.7% of the data falls within three standard deviations from the mean. Given the mean of 68 and standard deviation of 4, 99.7% of the heights would range from 56 to 80 inches. Therefore, the answer is option A.

The question is about the normal distribution, a key concept in statistics. In a normal distribution, about 68% of the values fall within one standard deviation around the mean, 95% fall within two standard deviations, and 99.7% fall within three standard deviations. Since the mean height of the population is 68 inches and the standard deviation is 4 inches, three standard deviations from the mean would be 12 inches above and below the mean. Hence, 99.7% of the population's height would fall within the range of 68 inches - 12 = 56 inches and 68 inches + 12 = 80 inches.

So, the correct answer to this question is option A: 56 inches to 80 inches.

The range within which 99.7% of the population will have a height can be found using z-scores. The correct answer is option A. 56 inches to 80 inches

To find the range within which 99.7% of the population will have a height, we need to use the concept of z-scores.

The range is usually defined as the mean plus or minus a certain number of standard deviations.

In this case, 99.7% of the population would fall within three standard deviations of the mean.

So, the range would be 68 - (3 * 4) = 56 inches to 68 + (3 * 4) = 80 inches.

Therefore, the correct answer is A. 56 inches to 80 inches.

Answer:

She should cut each diagonal piece 10 ft long.

Step-by-step explanation:

The bottom face of the box is a rectangle 8 ft by 6 ft.

A diagonal of a rectangle divides the rectangle into two congruent right triangles. With a right triangle you can use the Pythagorean theorem.

a = length of rectangle = leg of right triangle

b = width of rectangle = other leg of right triangle

c = diagonal of rectangle = hypotenuse of right triangle

a^2 + b^2 = c^2

(8 ft)^2 + (6 ft)^2 = c^2

64 ft^2 + 36 ft^2 = c^2

c^2 = 100 ft^2

Take the square root of each side.

c = 10 ft

Answer: She should cut each diagonal piece 10 ft long.

Answer:

Sara is 4 ft tall

Step-by-step explanation:

Let

x ----> the height of Sarah

using proportion

[tex]\frac{50}{75}=\frac{x}{6} \\ \\x=6*50/75\\ \\x= 4\ ft[/tex]

Final answer:

Using the properties of similar triangles, the height of Sarah is found to be 4 feet tall, given the proportions between the building's height and shadow and Sarah's shadow.

Explanation:

The question requires us to use the properties of similar triangles to find the height of Sarah given that a building 50ft high casts a 75ft shadow and Sarah casts a 6ft shadow. Since the triangles are similar, their sides are in proportion.

To find Sarah's height, we can set up a proportion using the corresponding sides of the similar triangles:

Building's height / Building's shadow = Sarah's height / Sarah's shadow

50ft / 75ft = Sarah's height / 6ft

To solve for Sarah's height, we can cross-multiply and divide:

(50ft × 6ft) / 75ft = Sarah's height

300ft² / 75ft = 4ft

Therefore, Sarah is 4 feet tall.

[tex](4 + 9i)(7 - 4i) = 4(7 - 4i) + 9i(7 - 4i)[/tex]

[tex](4 + 9i)(7 - 4i) = 28- 16i + 63i - 36 {i}^{2} [/tex]

Recall that,

[tex] {i}^{2} = - 1[/tex]

Our expression now simplifies to:

[tex](4 + 9i)(7 - 4i) = 28 + 47i + 36 [/tex]

[tex](4 + 9i)(7 - 4i) = 64 + 47i [/tex]

Answer: [tex]64+47i[/tex]

Step-by-step explanation:

Given the Complex numbers multiplication:

[tex](4+9i)(7-4i)[/tex]

You need to follow these steps:

1. Apply Distributive property:

[tex](4+9i)(7-4i)=(4)(7)+(4)(-4i)+(9i)(7)+(9i)(-4i)=28-16i+63i-36i^2[/tex]

2. You need to remember that:

[tex]i=\sqrt{-1}\\\\i^2=-1[/tex]

Then, you need to substitute [tex]i^2=-1[/tex]:

 [tex]28-16i+63i-36(-1)=28-16i+63i+36[/tex]

3. Finally, add the like terms:

By factorising a function, you can find the value of x-intercepts by substituting f(x)=0

By plotting a graph, you can check the values of x-intercepts

A function graph can be used to verify if a function is factored correctly by comparing the x-intercepts on the graph to the solutions of the factored function.

A function graph can be used to help verify that a function is factored correctly by examining its x-intercepts. When a function is factored correctly, the x-intercepts represent the values of x for which the function equals zero. In other words, they are the solutions to the equation f(x) = 0. By plotting the function and identifying the x-intercepts on the graph, we can compare them to the solutions of the factored function to determine if they match.

For example, let's say we have a function f(x) = (x+2)(x-3). The factored form suggests that the x-intercepts should occur at x = -2 and x = 3. By graphing the function and observing where it crosses the x-axis, we can confirm if these values are indeed the x-intercepts.

If the x-intercepts on the graph match the solutions of the factored function, it indicates that the function is correctly factored. However, if they do not match, it suggests an error in the factoring process.
