A box contains several copies of Mrs. Spencer's new pamphlet. The box weighs 2,000 grams. This chart

Answers

Answer:

This example represents discrete data.

Step-by-step explanation:

Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.

In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.

Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

This is an example of discrete data

What is the expanded form of this number?

902.604


(9×100)+(2×10)+(6×110)+(4×1100)


(9×100)+(2×1)+(6×110)+(4×1100)


(9×100)+(2×1)+(6×110)+(4×11000)


(9×100)+(2×10)+(6×110)+(4×11000)

Answers

Answer:

(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

Step-by-step explanation:

(9 × 100) + (2 × 10) + (6 × 110) + (4 × 1100) = 900 + 20 + 660 + 4400

900 + 20 + 660 + 4400 = 5980

(9 × 100) + (2 × 1) + (6 × 110) + (4 × 1100) = 900 + 2 + 660 + 4400

900 + 2 + 660 + 4400 = 5962

(9 × 100) + (2 × 1) + (6 × 110) + (4 × 11000) = 900 + 2 + 660 + 44000 = 45562

(9 × 100) + (2 × 10) + (6 × 110) + (4 × 11000) = 900 + 20 + 660 + 44000

900 + 20 + 660 + 44000 = 45580

None of your options work. The answer would be:

(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

900 + 2 + 0.6 + 0.004

902.604

The solution is: the expanded form of this number 902.604 is:

(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

What is  multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here, we have,

(9 × 100) + (2 × 10) + (6 × 110) + (4 × 1100) = 900 + 20 + 660 + 4400

900 + 20 + 660 + 4400 = 5980

(9 × 100) + (2 × 1) + (6 × 110) + (4 × 1100) = 900 + 2 + 660 + 4400

900 + 2 + 660 + 4400 = 5962

(9 × 100) + (2 × 1) + (6 × 110) + (4 × 11000) = 900 + 2 + 660 + 44000 = 45562

(9 × 100) + (2 × 10) + (6 × 110) + (4 × 11000) = 900 + 20 + 660 + 44000

900 + 20 + 660 + 44000 = 45580

None of your options work.

The answer would be:

(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

900 + 2 + 0.6 + 0.004

902.604

Hence, The solution is: the expanded form of this number 902.604 is:

(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

answer: 1/7

the formula for slope is rise over run, or y1-y2 divided by x1-x2. we can choose either number as y1 or y2 but it needs to stay consistent with x

so let’s plug in from your table.

0-1 divided by -7 -0
(you could also do 1-0 divided by 0-(-7))

-1/-7 which equals 1/7

so, your slope is 1/7

A circular fountain has a radius of 6.1 feet. Find its diameter and circumference to the nearest hundredth. Use 3.14 for π.

Answers

Answer:

d= 12.2 C= 38.3

Step-by-step explanation:

The radius of a circle is half of the diameter so multiply 6.1 by 2

6.1 x 2 = 12.2 ft

To find the circumference:

C = 2πr

C = 2(3.14)(6.1)

C= 2(19.154)

C= 38.3

andre is traveling from jeffersonville to springfield. he plans to stop for a break when the distance he has traveled and the distance he has left to travel have a ratio of 3:7. where should andre stop for his break? jeffersonville, J (-15, 2). springfield, S (25, 17)

Answers

Answer:

Andre should stop at (-3 , 6.5)

Step-by-step explanation:

The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3

The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.

she should stop at (-3, 6.5 )
