Step-by-step explanation:

if 32 was originally there now some left and 21 are left we can pit it into a subtraction equation.

32-?=21

we can also make an addition equation

21+?=32

we know that ?= 11 because of commen scene.

Answer: 32-(__)=21

Step-by-step explanation:

I like to think of what I'm given to be the left side, and what's after to be the right side. If there are 32 originally, then you take some away (since 21 is fewer than 32), that's subtracting by some number. Then, we have 21 left so put 21 on the right side. To solve, subtract the 21 from the 32 and add the unknown over to get (__)=9

The slope of CD = 0.6.

The slope of DE = -1/3.

The slope of EC = 0.5.

The length of CD = √136 units.

The length of DE = √40 units.

The length of EC = √80 units.

Triangle CDE is a scalene triangle.

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) CD = (5 + 1)/(4 + 6)

Slope (m) CD = 6/10

Slope (m) CD = 0.6.

Slope (m) DE = (3 - 5)/(2 + 4)

Slope (m) DE = -2/6

Slope (m) DE = -1/3.

Slope (m) EC = (3 + 1)/(2 + 6)

Slope (m) EC = 4/8

Slope (m) EC = 0.5.

Next, we would determine the length of each sides of triangle CDE as follows;

Distance CD = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance CD = √[(4 + 6)² + (5 + 1)²]

Distance CD = √136 units.

Distance DE = √[(2 + 4)² + (3 - 5)²]

Distance DE = √40 units.

Distance EC = √[(2 + 6)² + (3 + 1)²]

Distance EC = √80 units.

The approximate population density of the city is 1,005 people/mi²

The correct answer choice is option D.

Population density can be defined as the number of people in a geographic location at a particular time. It is calculated by dividing the total area of a region by the total number of people that live in that area.

Number of square grids = 107

Land mass = 0.75 miles

Number of people = 60, 500

One square grid = 0.75 × 0.75

= 0.5625 square miles

Total area = Area × Number of square grids

= 0.5625 square miles × 107

= 60.1875 square miles

Population density = Number of people / Total area

= 60,500 /60.1875 square miles

= 1005.192107995846

Approximately,

1,005 people/mi²

It's important to note that this calculation assumes that the items in each category are distinct and that Soo Jin can select any item from each category without any restrictions or dependencies.

To determine the number of different possible characters Soo Jin can create for the video game, we need to consider the combinations of items from each category.

Let's assume there are n1 items in Category 1, n2 items in Category 2, n3 items in Category 3, and n4 items in Category 4. To find the total number of possible characters, we multiply the number of options in each category:

Total number of characters = n1 * n2 * n3 * n4

For example, if Category 1 has 5 items, Category 2 has 3 items, Category 3 has 2 items, and Category 4 has 4 items, the total number of possible characters would be:

Total number of characters = 5 * 3 * 2 * 4 = 120

There are 720 different completed answer sheets possible, where no blanks are allowed.

In this problem, we have 6 questions and 6 different answers to match with each question. We need to determine how many different completed answer sheets are possible, where no blanks are allowed. To solve this, we'll use combinatorics and permutations.

To find the number of different completed answer sheets, we can consider each question as a distinct entity. Let's label the questions as Q1, Q2, Q3, Q4, Q5, and Q6. Similarly, let's label the answers as A1, A2, A3, A4, A5, and A6.

Since each question needs to be matched with a different answer, we can think of this as a one-to-one mapping between the questions and answers. In other words, we want to find the number of permutations of the answers that satisfy the matching condition.

The first question (Q1) can be matched with any of the 6 answers (A1, A2, A3, A4, A5, or A6). Once Q1 is matched, the second question (Q2) can be matched with any of the remaining 5 answers. Similarly, the third question (Q3) can be matched with any of the remaining 4 answers, and so on.

Using the fundamental principle of counting, we can multiply the number of choices available for each question.

The number of possible completed answer sheets is given by:

Number of completed answer sheets = 6 * 5 * 4 * 3 * 2 * 1 = 720.

So, there are 720 different completed answer sheets possible, where no blanks are allowed.

There are 792 different ways the teams can be formed from a group of 12 people when selecting 5 people for each team.

To determine the number of different ways the teams can be formed, we can use the concept of combinations. In this case, we need to select 5 people out of a total of 12.

The number of ways to choose a team of 5 out of 12 people can be calculated using the formula for combinations, which is denoted as "nCr" or "C(n, r)".

The formula for combinations is:

nCr = n! / (r!(n - r)!)

Where:

n is the total number of people (12 in this case)

r is the number of people to be selected for the team (5 in this case)

! denotes the factorial function

Now let's calculate the number of different ways the teams can be formed:

12C5 = 12! / (5!(12 - 5)!)

= 12! / (5! * 7!)

= (12 * 11 * 10 * 9 * 8) / (5 * 4 * 3 * 2 * 1)

= 792

The total number of carrots and cauliflower is 27, and the number of tomatoes is 19.

Explanation:

Let the number of carrots be c and the number of cauliflower be f.

From the given information, we know that:

c + f = 27 ----(1) (total number of carrots and cauliflower)

19 = tomatoes

We are asked to find the values of c and f. To do this, we can use the equation (1) and substitute 19 for f:

c + 19 = 27

c = 27 - 19

c = 8

Therefore, the number of carrots is 8. To find the number of cauliflower, we can use the equation (1) and substitute the value of c:

8 + f = 27

f = 27 - 8

f = 19

Therefore, the number of cauliflower is 19. Hence, the total number of carrots and cauliflower is:

c + f = 8 + 19 = 27

And the number of tomatoes is:

tomatoes = 19

So, the given information can be summarized as 8 carrots, 19 cauliflower, and 19 tomatoes.

Answer: It means Undo

Step-by-step explanation:

Step-by-step explanation:

In a parallelogram, opposite sides are equal in length. Therefore, we can set AD equal to CB and DC equal to AB to get two equations:

AD = CB

84 = 5x + 24

DC = AB

28 = 3x - 8

Solving the first equation for x, we get:

84 = 5x + 24

60 = 5x

x = 12

Solving the second equation for x, we get:

28 = 3x - 8

36 = 3x

x = 12

Since both equations give us x = 12, we can conclude that the value of x that makes ADCB a parallelogram is x = 12.

To verify, we can check that the opposite sides are equal in length:

AD = 84 cm

CB = 5x + 24 = 5(12) + 24 = 84 cm

DC = 28 cm

AB = 3x - 8 = 3(12) - 8 = 28 cm

Both pairs of opposite sides have the same length, so ADCB is a parallelogram when x = 12.

Answer:

x = 3.0

Step-by-step explanation:

This makes ADCB a parallelogram, with AD as its base and AB and CB as its two parallel sides.

The point estimate of the population mean is 2.02 liters, and the 95% margin of error for this estimate is 0.0197 liters. To reduce this margin of error to 1/3 of its current size, a sample size of at least 121 bottles would be required.

The point estimate of the population mean is simply the sample mean, which is 2.02 liters.
To calculate the margin of error, we need to use the formula: margin of error = z * (standard deviation / sqrt(sample size)), where z is the critical value for a 95% confidence interval (which is 1.96), and sqrt stands for square root. Plugging in the given values, we get: margin of error = 1.96 * (0.07 / sqrt(50)) = 0.0197 liters.
To make the margin of error 1/3 as large as it is in part (b), we need to divide the margin of error by 3, and then solve for the required sample size in the margin of error formula. That is: 0.0197 / 3 = z * (0.07 / sqrt(sample size)), where z is still 1.96. Solving for the sample size, we get: sample size = (z * standard deviation / margin of error)^2 = (1.96 * 0.07 / 0.0197)^2 = 120.79. Therefore, we would need a sample size of at least 121 bottles to achieve the desired margin of error.
In conclusion, the point estimate of the population mean is 2.02 liters, and the 95% margin of error for this estimate is 0.0197 liters. To reduce this margin of error to 1/3 of its current size, a sample size of at least 121 bottles would be required.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

The statement, "two non-zero vectors "a" and "b" satisfy a×b = 0 then "a" and "b" are parallel" is True, because the cross-product of two vectors is always 0.

The "Cross-Product" of "two-vectors" is zero only when the vectors are parallel or when one (or both) of the vectors is the zero vector. Since a × b = 0 and both "a" and "b" are non-zero, it implies that "a" and "b" are parallel. This is because the cross product of parallel vectors is always zero.

Therefore, the condition a × b = 0 serves as a test for parallelism between non-zero vectors, so the statement is True.

The probability that a student who passed the test did not complete the homework is 4/15.

We can use conditional probability to solve this problem. Let A be the event that a student passed the test, and let B be the event that a student completed the assignment. Then we want to find the probability of A given not B, denoted as P(A | not B).

From the given information, we know that:

- P(A) = 18/27 = 2/3 (since 18 out of 27 students passed the test)

- P(B) = 17/27 (since 17 out of 27 students completed the assignment)

- P(A and B) = 15/27 (since 15 out of 27 students passed the test and completed the assignment)

To find P(A | not B), we first need to calculate P(not B), the probability that a student did not complete the assignment. This can be found using the complement rule:

P(not B) = 1 - P(B) = 1 - 17/27 = 10/27

Now we can use Bayes' theorem to find P(A | not B):

P(A | not B) = P(not B | A) * P(A) / P(not B)

We can find P(not B | A) using the formula:

P(not B | A) = P(A and not B) / P(A)

We know that P(A and B) = 15/27, so P(A and not B) = P(A) - P(A and B) = 2/3 - 15/27 = 4/27. Substituting into the formula:

P(not B | A) = (4/27) / (2/3) = 2/9

Substituting this value, along with the values we previously calculated, into Bayes' theorem:

P(A | not B) = (2/9) * (2/3) / (10/27) = 4/15

1. To round $5/11 = 0.\overline{45}$ to the nearest whole number, we look at the digit in the ones place, which is 5. Since 5 is greater than or equal to 5, we round up to the next whole number, which is 1. Therefore, rounded to the nearest whole number, $5/11$ is equal to 1.

2. To round $5/11 = 0.\overline{45}$ to the nearest tenth, we look at the digit in the hundredth place, which is 5. Since 5 is greater than or equal to 5, we round up to the next tenth, which is 0.5. Therefore, rounded to the nearest tenth, $5/11$ is equal to 0.5.

3. To round $5/11 = 0.\overline{45}$ to the nearest hundredth, we look at the digit in the thousandth place, which is also 5. Since 5 is greater than or equal to 5, we round up to the next hundredth, which is 0.46. Therefore, rounded to the nearest hundredth, $5/11$ is equal to 0.46.

4. To round $5/11 = 0.\overline{45}$ to the nearest thousandth, we look at the digit in the ten thousandth place, which is 4. Since 4 is less than 5, we round down to 0.455. Therefore, rounded to the nearest thousandth, $5/11$ is equal to 0.455.

5. To round $5/11 = 0.\overline{45}$ to the nearest ten thousandth, we look at the digit in the hundred thousandth place, which is 5. Since 5 is equal to 5, we round up if the digit in the ten thousandth place is odd, and round down if it is even. In this case, the digit in the ten thousandth place is 4, which is even, so we round down to 0.4550. Therefore, rounded to the nearest ten thousandth, $5/11$ is equal to 0.4550.

6. To round $5/11 = 0.\overline{45}$ to the nearest hundred thousandth, we look at the digit in the millionth place, which is also 5. Since 5 is equal to 5, we round up if the digit in the hundred thousandth place is odd, and round down if it is even. In this case, the digit in the hundred thousandth place is even, so we round down to 0.45499. Therefore, rounded to the nearest hundred thousandth, $5/11$ is equal to 0.45499.

When Tony rounds $0.\overline{45}$ to the nearest hundred thousandth, he gets 0.45499, which he then rounds to 0.4550, and so on, following the same steps we did above. His final answer for question 1 will be 0, since rounding 0.5 to the nearest whole number gives 0. Therefore, Tony's final answers will be:
