Answer:

It is not valid since there is more than one variable being changed at one.

Step-by-step explanation:

The probability of a middle school student owning a skateboard is 0.58, of owning a bicycle is 0.48 and of owning both is 0.45.
Vera_Pavlovna [14]

Answer:

The probability that the middle school student owns a skateboard or a bicycle is 0.61.

Step-by-step explanation:

We are given that the probability of a middle school student owning a skateboard is 0.58, of owning a bicycle is 0.48, and owning both is 0.45.

A middle school student is chosen at random.

Let the probability of student owning a skateboard = P(S) = 0.58

The probability of student owning a bicycle = P(B) = 0.48

The probability of student owning both = P(S \bigcap B) = 0.45

Now, the probability that the middle school student owns a skateboard or a bicycle is given by = P(S \bigcup B)

        P(S \bigcup B) = P(S) + P(B) - P(S \bigcap B)

                      = 0.58 + 0.48 - 0.45

                      = 0.61

Hence, the probability that the middle school student owns a skateboard or a bicycle is 0.61.

What is the correct order of steps to change 4x+2y=14 from standard to slope intercept form
inn [45]

Slope intercept form is y = -2x + 14

Step-by-step explanation:

  • Step 1: The original equation is 4x + 2y = 14.
  • Step 2: Rearrange so that x is first in the right hand side of the equation.

⇒ 2y = - 4x + 14

  • Step 3: Subtract 4x from both sides of the equation.

⇒ 2y = 14 - 4x

  • Step 4: Divide both sides of the equation by 2 so that coefficient of y is 1.

⇒ y = - 2x + 7

This is the slope intercept form y = mx + b

Jonita determined that the distance between her apartment and the nearest hospital was more than 1,600 meters but less than 1,90
Bess [88]

Answer: 1.8 x 103 meters

Step-by-step explanation:

The average of the two extremes is 1,700 meters.  This would be 1.7x10^3 in scientific notation.  None of the four options include this number.  But three stand out as total losers.  We can convert the answer options to see the difference:

O 1.7 x 102 meters  =    170 meters      [Loser]

O 1.8 x 103 meters  =  1800 meters

O 1.7 x 10-3 meters =  0.0017 meters   [Loser]

O 1.8 x 10-2 meters =  0.018 meters     [Loser]
