The mean: 157 cm

The mode: 157 cm

The median: 157 cm

The range: 10 cm

Step-by-step explanation:

To calculate the mean add all the heights and divide them by the number of heights.

(159 + 155 + 153 + 154 + 157 + 162 + 152 + 160 + 161 + 157) ÷ 10 =  157 cm

The mode is 157 cm because that is the most frequent number.

The median height is the middle number, so first place them in order.

152, 153, 154, 155, 157, 157, 159, 160, 161, 162

The median height is 157 cm

The range is the difference between the highest and lowest number.

162 - 152 = 10

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

(a + b) (a^2 - a b + b^2)

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
