Answer: 142.58\text{squared kg}[

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given : A random sample of 10 subjects have weights with a standard deviation of 11.9407 kg

i.e. \sigma = 11.9407

Since we know that the value of variance is the square of standard deviation.

i.e. \text{Variance}=\sigma^2

Therefore, to find the value of variance, we need to find the square of the given standard deviation.

i.e. \text{Variance}=(11.9407)^2=142.58031649\approx142.58\text{squared kg}

Thus, the variance of their​ weights =142.58\text{squared kg}[

variables y and x have a proportional relationship and y = 15 when x = 6. what is the value if x when y = 35
Ira Lisetskai [31]

Answer:

x = 14

Step-by-step explanation:

y and x have a proportional relationship. That means that I can multiply them both or divide them both by the same thing and still stay proportional.

when y = 15, x = 6

when y = 5, x = 2 (divided by 3)

when y = 35, x = 14 (multiplied by 7)

A rectangle is 4 times longer than it is wide. The perimeter of the rectangle is 30 cm. Find the dimension of the rectangle.
kenny6666 [7]

Width is 3 cm and length is 12 cm

Step-by-step explanation:

  • Step 1: Let the width of the rectangle be x. Then the length = 4x. Find the dimensions if perimeter = 30 cm

Perimeter of the rectangle = 2 (length + breadth)

30 = 2(x + 4x)

30 = 10x

⇒ x = 30/10 = 3

⇒ 4x = 12
