<span>For the normal distribution:
one standard deviation from the mean accounts for about 68.2% of the set

</span><span>two standard deviations from the mean account for about 95.4%
and three standard deviations from the mean account for about 99.7%.
Important to Understand z -values as they relate to the Standard Normal curve:
Below: z = 0, z = ± 1, z= ±2 , z= ±3 are plotted.
Note: z = 0 (x value the mean) 50% of the area under the curve is to the left and 50% to the right</span>

Answer:

16/24 and 12/18, in simplest form 2/3

Step-by-step explanation:

8 parts juice

fruit and crushed ice = 3 + 9 = 12

ratio of juice to fruit and crushed ice is 8:12 or 8/12

8/12 (2/2) = 16/24

8/12 (1.5/1.5) = 12/18

in simplest form

8/12 (1/4 / 1/4) = 2/3

A rectangle has an area of 120 square cm. Its length and width are whole numbers. List the possible dimensions of the rectangle.
Nadusha1986 [10]

Answer: kindly check explanation

Step-by-step explanation:

Given that:

Area of rectangle = 120 cm²

Assume ; Length and width are whole numbers

Possible dimension of the rectangle will be :

Area of a rectangle = Length × width

Area = 120cm²

Possible dimensions :

80cm by 1 cm

40cm by 2cm

20cm by 4cm

10cm by 8cm

5cm by 16cm

Possibility which gives the smallest perimeter :

Dimension = 10cm by 8cm

Perimeter of Rectangle = 2(length + width)

Perimeter of Rectangle :

= 2(10 + 8)cm

= 2(18)cm

= 36cm
