Caleb is participating in a walk-a-thon. His goal is to walk as far as possible over an 8-hour period.
luda_lava [24]

Caleb is participating in a walk-a-thon. His goal is to walk as far as possible over an 8-hour period.

For the first 3 hours, he keeps a steady pace of 2 miles per hour.

He then stops walking while he takes a 1-hour break for lunch.

It's too short. Write at least 20 characters to explain it well.

An investigative bureau uses a laboratory method to match the lead in a bullet found at a crime scene with unexpended lead cartr
Basile [38]

Answer / Step-by-step explanation:

In this exercise, we know that the agency collected 1,829 bullets which according to the agency, all came from different source.

The number of pair of bullet is :

         (1,829) = 1, 829 ! / 2! ( 1,829 - 2 ) = 1, 829 x 1,828 x 1827 ! / 2 x 1 x 1,827

          (   2   )

                   = 6, 108,413,724 / 3654

                   = 1671,706.

Also, we know that the agency found 658 matches. According to this, the chance of false positive ( that is, the agencies find a match but the bullets are from two different source ) is

   P (False positive ) = 658 / 671,706

                                   = 0.000979.

The probability is small to an extent, therefore, we should have confidence in the agency forensic report and evidence

<u>Trigonometry</u>

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

Leg <em>a</em> = <em>a</em>

Leg <em>b</em> = 12

Hypotenuse <em>c</em> = 20

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Substitute in variables [Pythagorean Theorem]:                                            a² + 12² = 20²
  2. Evaluate exponents:                                                                                         a² + 144 = 400
  3. [Subtraction Property of Equality] Isolate <em>a</em> term:                                           a² = 256
  4. [Equality Property] Square root both sides:                                                    a = 16

The lengths of the sides of the triangle are 3, 8, and 10. Is the triangle a right triangle, acute triangle, or an obtuse triang
weqwewe [10]

Answer:

Obtuse

Step-by-step explanation:

  1. You have to make sure it is a triangle by adding the smallest and the medium sides, if the result is greater than the bigger side then it is a triangle.
  2. you then use the Pythagorean theorem to check if the triangle is a right triangle, acute, or obtuse. If c^{2} = a^{2} +b^{2} then it is a right triangle. If c^{2} >a^{2} + b^{2} then it is an obtuse triangle. if c^{2} < a^{2} +b^{2} then it is an acute triangle.
  1. 10^{2} _ 3^{2} + 8^{2}
  2. 9+64_100
  3. 70_100
  4. 70<100

in this case c^{2} is greater than a^{2} +b^{2} therefore, is it an obtuse triangle.
