One way is to find common factors

example

8/6=4/3 because 8/6, 8 and 6 have common factor of 2 so divide that out to get 4/3
basically divide the LCM from each

so factor

we can combine 36m-48m into -12m
we have
-12m/6m

common factor is 6m
-12m/6m=(-2)/1 times (6m)/(6m)=-2 times 1=-2

answer is -2

<h3>Answer:  34%</h3>

This result is approximate.

=========================================================

Explanation:

mu = 750 = mean

sigma = 75 = standard deviation

The raw scores or x values are x = 750 and x = 825

Let's compute the z score for each x value

z = (x - mu)/sigma

z = (750 - 750)/75

z = 0

and

z = (x - mu)/sigma

z = (825 - 750)/75

z = 1

Therefore P(750 ≤ x ≤ 825) is equivalent to P(0 ≤ z ≤ 1) in this context.

Use a z score table to determine that

P(z ≤ 0) = 0.5

P(z ≤ 1) = 0.84314 approximately

So,

P(a ≤ z ≤ b) = P(z ≤ b) - P(z ≤ a)

P(0 ≤ z ≤ 1) = P(z ≤ 1) - P(z ≤ 0)

P(0 ≤ z ≤ 1) = 0.84314 - 0.5

P(0 ≤ z ≤ 1) = 0.34314 approximately

The value 0.34314 then converts to 34.314% which rounds to <u>34%</u>

Or you could use the empirical rule as shown below. The pink section on the right is marked <u>34%</u> which is approximate. This pink section is between z = 0 and z = 1.

A 45 kg skydiver has a speed of 25 m/s at an altitude of 950 meters above the ground. Determine the
Montano1993 [528]

The kinetic energy possessed by the skydiver is 14, 062. 5 Joules

<h3>What is kinetic energy?</h3>

Kinetic energy of an object is defined as the energy possessed by an object due to its motion.

It is also described as the work that is required to accelerate a body of mass from rest to its given velocity.

The formula for calculating kinetic energy is expressed as;

Kinetic energy = 1/2 mv²

Where;

  • m is the mass of the object
  • v is the velocity of the object

Now, substitute the values

Kinetic energy = 1/2 (45)(25)²

Find the square

Kinetic energy = 1/2 (45)(625)

Find the product

Kinetic energy = 1/2(28125)

Find the quotient

Kinetic energy = 14, 062. 5 Joules

Hence, the value is  14, 062. 5 Joules

You have 16 digs for your current volleyball season. There are 3 games left in the season. You want to break your previous recor
g100num [7]

Answer:

we must get more than 4 digs in the remaining 3 games break record of 20

Step-by-step explanation:

given data

current volleyball season = 16 digs

games left in the season = 3

previous record = 20 digs

solution

we consider here the number of digs  x that must get in the remaining 3 games to break your record

so for break  previous record of 20 digs, we have to get more than 20  

so 16 digs must add to x to greater than 20

x + 16  ≥ 20   ...............................1

so x will be

x ≥ 20 - 16

x ≥ 4  

so that we must get more than 4 digs in the remaining 3 games break record of 20
