Step-by-step explanation:
000,000 the underlined number is the tens place. In order for the tens place to round up the ones place must be 5 or above. If the ones place is lower than 5 you round down to the nearest tens.
In Example:
333,389 you would round up to 333,390 because of the 9 in the ones place.
Now, 333,333 you would round down to 333,330 because of the 3 in the ones place

A. Minor arc
B. Semicircle C. Major arc
Answers
Answer:
B. Semicircle
Step-by-step explanation:
Semicircle means "half of a circle"
A minor arc is when the arc has a degree of less than 180°
A major arc is when the arc has a degree of more than 180°
If the degree is exactly 180°, then it's a semicircle. And it tells you the degree, which is 180°

what is a compound inequality that represents all real numbers that are greater than -8 but less than 8
Answers
Answer:
The inequality is "-8 < x < 8" that can also be expressed as x > - 8 and x < 8
Step-by-step explanation:
In this case there are two inequalities. The first one is for all real numbers that are greater than -8. In this case we will represent the real numbers as "x" and this inequality can be represented as:
x > - 8
The second inequality is for all real numbers that are less than 8, this can be represented as:
x < 8
To create the compound inequality we have two use both of the inqualities above:
-8 < x < 8
x > - 8 and x < 8
In this case we use and because the real number must satisfy both inequalities at the same time.
Find the sum -6/3 - (-7/15)
Answers
Answer:
-1 [tex]\frac{8}{15}[/tex]
Step-by-step explanation:
That's the answer I think
Answer:
- 23/15 or - 1 8/15
Step-by-step explanation:
When you want to subtract fractions, you first want to see if they have the same denominator. In this case, there isn't a common denominator so we need to make it so there is. Since 15 is the larger one and a multiple of 3, we can change -6/3 to -30/15 by multiplying the top and bottom by 5. Now the double negatives cancel each other out so instead of -30/15 - (-7/15), it will be -30/15 + 7/15. Add them together and you get -23/15.
What is the volume of a 3 foot tall cylindrical trash can with a 1 foot radius
Answers
The volume of the cylindrical trash can with a 1 foot radius and 3 foot height is 9.426 cubic feet.
Explanation:The volume of a 3-foot tall cylindrical trash can with a 1-foot radius can be calculated using the formula V = πr²h, where r is the radius and h is the height.
Given that the radius is 1 foot and the height is 3 feet, we can substitute these values into the formula:
V = 3.142 × (1 foot)² × 3 feet = 9.426 cubic feet
Therefore, the volume of the trash can is 9.426 cubic feet.

A population has a standard deviation of 5.5. What is the standard error of
the sampling distribution if the sample size is 49? Round your answer to two
decimal places.
Answers
Answer:
The standard error of the sampling distribution is [tex]\sigma_x = .79[/tex].
Step-by-step explanation:
We can find the standard error of the sampling distribution using this formula:
The standard deviation of the sampling distribution, also known as the standard error, can be found by taking the population standard deviation and dividing it by the square root of the sample size, both of which we are given in the problem.
[tex]\displaystyle \sigma_x = \frac{5.5}{\sqrt{49 }} = .7857[/tex]Rounded to two decimal places: [tex]\sigma_x = .79[/tex]
The standard error of the sampling distribution if the sample size n = 49 and the population standard deviation σ = 5.5 is .79.

Answers:
A: mean=mode
B: mode=median
C: mean < median
D: mode > mean
Answers
Answer:
b
Step-by-step explanation:
Because there are two sixes so that is the mode and the middle is 6 so that would be the middle and both of them are six so the answer would be B
The mode and the median have the same value which is 6. Therefore, option B is the correct answer.
The given data set is 4, 5, 6, 6, 7, 9, 12.
What is the mode?The mode is the value that appears most frequently in a data set. A set of data may have one mode, more than one mode, or no mode at all.
The mode of the given data is 6.
Median: The median is the middle number in a sorted, ascending or descending list of numbers and can be more descriptive of that data set than the average.
The median of the given data is 6.
Mean = (4+5+6+6+7+9+12)/7
=49/7 = 7
Here, the mode and the median have the same value which is 6. Therefore, option B is the correct answer.

Answers
Answer:86 tends to increase
Step-by-step explanation:
just did this
After 5 hours of studying, expected score will be 86.
As the number of hours studying increases, the corresponding test scores also tends to increase.
What is Scatterplots?Scatterplots are the plotting of set of points on a vertical axis and an horizontal axis. The shows the correlation extent between the numbers of the observed quantities.
Given is a table containing the hours studied, x and the corresponding test scores, y of five students.
x : 1 2 4 7 8
t : 76 81 89 87 91
The trend line is drawn below.
The trend line passes through (2, 81) and (8, 91).
Slope of the line = (91 - 81) / (8 - 2) = 10/6 = 5/3
Equation is of the form y = 5/3 x + c
Substituting the point (2, 81),
81 = 10/3 + c
c = 233/3
Equation of the line is y = 5/3 x + 233/3
When x = 5, y = (5/3 × 5) + 233 / 3 = 86
Hence after 5 hours of studying, there will be a score of 86.
As the number of hours studying increases, the corresponding test scores also tends to increase.
Hence the trend line is given below.

In the Three-Dimensional Figures and Cross Sections section, what is the difference between a prism and a pyramid? *
Answers
Answer:
A prism has two identical bases that are parallel. A pyramid has one base. A prism or pyramid is named for the shape of its base.
Final answer:
The primary difference between a prism and a pyramid is their base shapes, the number of vertices, edges, and faces, with prisms having parallel and congruent bases while pyramids have triangular faces that meet at an apex.
Explanation:
The main difference between a prism and a pyramid lies in the shapes of their bases and the number of faces, edges, and vertices. A prism is a polyhedron that has two parallel and congruent faces called bases that are polygons of the same shape and size, and the other faces, known as lateral faces, are parallelograms resulting from connecting the corresponding vertices of the two bases. In contrast, a pyramid has a polygonal base and triangular faces that connect the base to a single point called the apex. A prism has as many lateral faces as the sides of its base, while a pyramid has as many triangular faces as the sides of the base polygon. Another way to distinguish them is by their vertices and edges; a prism will always have twice as many vertices and edges in the sides of the bases than a pyramid with the same shaped base.

Write an expression and solve it with the given values of the letters: b There are x candies in a bag. 4/9 of all the candies are chocolates. How many candies which are not chocolates are in the bag? (x=36)
Answers
Answer:
There are 20 candies which are not chocolates are in the bag.
Step-by-step explanation:
We are given the following in the question:
Number of candies in bag = [tex]x[/tex]
Number of candies that are chocolate =
[tex]\dfrac{4}{9}\text{ of the total candies}[/tex]
Number of chocolate candies in the bag =
[tex]=\dfrac{4}{9}\times x=\dfrac{4x}{9}[/tex]
We are given that x = 36.
We have to find the number of candies which are not chocolates are in the bag.
Number of chocolate candies in the bag =
[tex]=\dfrac{4}{9}\times 36 = 16[/tex]
There are 16 chocolate candies in the bag.
Number of candies that are not chocolate =
[tex]= 36-16\\=20[/tex]
Thus, there are 20 candies which are not chocolates are in the bag.
