Answer:
17.1
Step-by-step explanation:
1. Find the Mean
(25+40+35+25+40+60+75)/7 = 42.9
2.For each number, subtract the Mean and square the result.
(25-42.86)^2=319
(40-42.86)^2=8.2
(35-42.86)^2=61.8
(25-42.86)^2=319
(40-42.86)^2=8.2
(60-42.86)^2=293.8
(75-42.86)^2=1033
3. Find the Mean of those squared differences.
(319+8.2+61.8+319+8.2+293.8+1033)/7=291.9
4.Take the square root of that and this is what you want.
square root of 291.9 = 17.1
Hi!
We will find the monthly budget using proportions, like this:
15% = 0,15___________600$
100% = 1_____________x$
__________________________
x = (600*1)/0,15
x = 600/0,15
x = 4000
Their monthly budget is 4000$.
Hope this helps!
Answer:
46.24 mm²
Step-by-step explanation:
Given:
s = 6.8 mm
To find the area of the <u>square</u>, simply square the measure of the <u>side length.</u>
⇒ Area of polygon = s²
<u>Substitute the measure of the side length:</u>
⇒ Area of polygon = (6.8)² [s = 6.8 mm]
<u>Simplify the area:</u>
⇒ Area of polygon = (6.8)(6.8)
⇒ Area of polygon = 46.24 mm²
Answer:
The size of the scale model is 60 centimeters.
Step-by-step explanation:
Given that the length of a boat is 10.8 m, and Boris buys a scale model of the boat whose ratio is 1 to 18, to determine the length of the scale model of the boat in centimeters the following calculation must be performed:
1m = 100cm
10.8 m = (10.8 x 100) = 1080 cm
1080/18 = X
60 = X
Therefore, the size of the scale model is 60 centimeters.
