Step-by-step explanation:
Selected theme park admission prices has the lower standard deviation.
Specific home stereo system's distribution is more spread out since the ratio between the standard deviation and the mean is greater compared to that of selected theme park admission prices.
specific home stereo system: 3.99/59=0.0676.
selected theme park admission prices: 4/1499=0.002668
0.0676>0.002668
Answer:
8 meters.
Step-by-step explanation:
Let the 2 radii be x and 2x, then
π x^2 + π (2x)^2 = 80π
π x^2 + π 4x^2= 80π
x^2 + 4x^2= 80
5x^2 = 80
x^2 = 16
x = 4.
So the radius of the larger circle = 2*4 = 8 m.
Answer:
4

Answer:
Area = 370 m²
Cost to paint = £105
Step-by-step explanation:
Area of the wall of a cinema hall = Area of a trapezoid (1)+ Area of a rectangle (2) + Area of a trapezoid (3)
Area of a trapezoid =
where
and
are the parallel sides and h is the distance between these sides.
Area of trapezoid (1) = ![\frac{1}{2}(11+12)\times 6](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%2811%2B12%29%5Ctimes%206)
= 69 m²
Area of the rectangle (2) = Length × Width
= 12 × 15
= 180 m²
Area of the trapezoid (3) = ![\frac{1}{2}(12+10)\times 11](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%2812%2B10%29%5Ctimes%2011)
= 121 m²
Now area of the wall = 69 + 180 + 121
= 370 m²
One tin covers the area = 25 m²
Number of tins required to paint the wall = ![\frac{\text{Total area}}{\text{Area covered by one tin}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BTotal%20area%7D%7D%7B%5Ctext%7BArea%20covered%20by%20one%20tin%7D%7D)
= ![\frac{370}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B370%7D%7B25%7D)
= 14.8
Therefore, number of tins to be purchased = 15
Cost to paint the complete wall = 15 × £7
= £105
