Answer:

2.42

Step-by-step explanation:

We are asked to consider a sample of blades for a circular saw, and their diameters were measured.

We are told they have a sample of variance, S²= 2.42

We are told to give a point estimate for the population variance in diameters of blades for the circular saw.

The sample variance, S² can be said to be a point estimate of the population variance.

Therefore, it can be said that the sample variance, S² is a point estimate for the population variance, b².

Which can also be written as:

b² = S²

b² = S² = 2.42

• The point estimate for the population variance is 2.42

The volume of box B is (A) 864 cubic meters.

<h3>What is volume?</h3>
  • The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity.
  • For example, the space occupied or contained by a substance or 3D object.
  • Volume is frequently mathematically quantified using the SI-derived unit, the cubic meter.

To find the volume of box B:

  • We have been assigned a volume of 32 cubic meters.
  • The cubic root of 32 yields the box's dimensions, which are 3.1748 x 3.1748 x 3.1748 meters.
  • Meters when the dimensions are tripled: 9.5244 x 9.5244 x 9.5244

= 864 cubic meters.

Therefore, the volume of box B is (A) 864 cubic meters.

Find the value of x for which allb <br> A. 35<br> B. 145<br> C. 140<br> D. 47
Paha777 [63]

Answer:

A. 35

Step-by-step explanation:

a || b .....(given)

line c is their transversal.

-> x° + (3x + 40)° = 180° (Interior angles on the same side of transversal)

-> (3x + 40 + x)° = 180°

-> (4x + 40)° = 180°

-> 4x + 40 = 180

-> 4x = 180 - 40

-> 4x = 140

-> x = 140/4

-> x = 35
