Jan buys 3 bags of beads. Each bag contains 7 beads. Draw a bar diagram and write an addition equation and a multiplication equa

-Dominant- [34]

Answer:

- The diagram bar is attached.

- Addition equation: $7+7+7=21$

- Multiplication equation: $(3)(7)=21$

- How are the equation related? Each equation shows 3 groups of 7.

Step-by-step explanation:

We know that Jan buys 3 bags of beads and each bag contains 7 beads, then, you can draw the bar diagram shown attached.

Observe that the diagram has 3 blocks (each block represents a bag of bead) and there is a number 7 inside of each block (which is the number of beads contained in a bag).

Therefore:

- Add the numbers inside the blocks in order to get the addition equation that shows the number of beads Jan buys. This is:

$7+7+7=21$

- Multiply 3 blocks by 7 in order to get multiplication equation that show the number of beads Jan buys:

$(3)(7)=21$

The equations are related. Each one shows 3 groups of 7.

My brother is in 6th grade and needs help with his math. I tried to help but I can't find any answers on it.

In-s [12.5K]

Answer:

Question 1) 17.4

Question 2) 1.7

Question 3) 2.8

Question 4) 8.6

Step-by-step explanation:

Mean absolute deviation is the average distance between the data points from the set to the mean point of the data set. It shows the variability in data or how much the data points are spread.

method to calculate Mean absolute deviation:

a. calculate mean

b. calculate absolute deviation of each data point

c. add all the deviations

d. divide absolute deviation by number of points

mean absolute deviation = ∑l $x_{i}$ -xl / n

The given problem has four sub-parts

Solution 1:

Mean= (78+99+90+80+55+56+102+88+60+42)/10

= 750/10

= 75

Mean absolute deviation= ( I 78-75 I + I 99-75 I+I 90-75 I + I 80-75 I +

I 55-75 I + I 56-75 I + I 102-75 I + I 88- 75 I +

I 60-75 I + I 42-75 I) /10

= (174)/10

= 17.4

Solution 2:

Mean = (10+13+7+12+9+8+12+10+11+13)/10

= (105)/10

= 10.5

Mean absolute deviation = ( I 10-10.5 I + I 13-10.5 I + I 7-10.5 I + I 12-10.5 I +

I 9-10.5 I + I 8-10.5 I + I 12-10.5 I + I 10-10.5 I +

I 11-10.5 I + I 3-10.5 I) /10

= 17/10

= 1.7

Solution 3:

Mean= (1+7+10+5+3+3+6+12+9+4)/10

= 60/10

= 6

Mean absolute deviation = ( I 1-6 I + I 7-6 I + I 10-6 I + I 5-6 I + I 3-6 I +

I 3-6 I + I 6-6 I + I 12- 6 I + I 9-6 I + I 4-6 I) /10

= (28)/10

= 2.8

Solution 4:

Mean= (30+46+25+45+18+25+15+32+40+24)/10

= 300/10

= 30

Mean absolute deviation = ( I 30-30 I + I 46-30 I + I 25-30 I + I 45-30 I +

I 18-30 I + I 25-30 I + I 15-30 I + I 32-30 I +

I 40-30 I + I 24-30 I) /10

= (86)/10

= 8.6

alexandr402 [8]

Answer:

Step-by-step explanation:

As per the given question,

In a manufacturing operation, a part is produced by machining, polishing, and painting.

Number of machine tools = 3

Number of polishing tools = 4

Number of painting tools = 3

Now,

For finding the different routing consisting of machining, followed by polishing, and followed by painting, we have to simply multiply the number of machine tools, polishing tools and painting tools.

Therefore,

The different routing (consisting of machining, followed by polishing, and followed by painting) for a part are possible = 3 × 4 × 3 = 36.

Hence, the required answer is 36.
