Answer:
The missing data value is 147
Step-by-step explanation:
If a point lies 3 standard deviations away from the mean, then the data point can be determined by simplifying the expression; μ±3σ. Where μ is the mean and σ the standard deviation. In this case this would be; 120±3(9)
Answer:
136 m²: 188 m²
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo
My answer:
Given the information:
- The height: 4m
- The lenght: 13m
- The width 4m
The lateral area:
As we know, the lateral area can be calculated by the following formula:
= the perimeter of the base* the height
= (13 + 4 + 13 + 4)*4
= 136 m²
The surface area:
As we know, the lateral area can be calculated by the following formula:
= The lateral area + thhe base area + the top area
= 136 + 13*4 + 13*4
= 136 + 52 + 52
= 240 m2
Answer:
528 cm²
Step-by-step explanation:
First I would calculate the area of the side rectangles:
20 x 9 = 180 cm²
There are two identical rectangles on both sides so i would x2
180 x 2 = 360 cm²
The area of the middle rectangle:
6 x 20 = 120 cm²
The area of the triangles:
Area of a triangle = (Base x Height)/2
8 x 6 = 48
48 ÷ 2 = 24
There are two identical triangles on the bottom and the top so x2
24 x 2 = 48
Now add all the values up:
360 + 120 + 48 = 528 cm²
I hope this helps!
So the pencils all together would be $6 so divide that by 3 and you get D as your answer each pencil costs $2
