Answer:

PArt 1: 4/40 (not simplified) 1/10 (simplified)

Part 2: 8/40 (not simplified) 2/10 (simplified)

Step-by-step explanation:

add all the marbles together and you get 40. there are 4 colors in the jar but with different amounts, you will divide 40 into each amount of marbles (example: 40/4 = 10 = there are 4 10s in 40).

A sample of 1500 people from a certain industrial community showed that 800 people suffered from a lung disease. A sample of 100
ss7ja [257]

Answer:

The probability that the difference of the proportions (industrial - rural) is greater than 0.2 is 0.7054

Step-by-step explanation:

Solution

Given that:

n₁ = 1500

x₁ = 800

p₁ =800/1500 =0.533

q₁ = 1- 0.533 = 0.467

Thus,

n₂ =1000

x₂ = 300

p₂ = 300/1000 = 0.3

q₂ = 1-0.3 =0.7

So,

p₁ - p₂ = 0.533 - 0.3

=0.233

Now,

SE (p₁ - p₂ ) =√0.533 * 0467/150 + 0.3 * 0.7/1000

=0.0613

So,

p ( p₁ - p₂  > 0.2

= p ( Ƶ > 0.2 - 0.233/0.0613

p = ( Ƶ > - 0.54)

= 0.7054

A firm makes bulldozers (B), cranes (C) and tractors (T) at two locations, New York City (NYC) and Los Angeles (LA). The matrice
iragen [17]

Answer:

The expression is  

.\ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ B \   \ \ \ \ \ C \ \ \ \ \ T\\M = \left \  NYC} \atop {LA}} \right.  \left[\begin{array}{ccc}{284}&{483}&{410}\\{597}&{551}&{233}{2}}\\\end{array}\right]

Step-by-step explanation:

From the question we are told that

    The  number of each items made in the month of January[J] is  

   .\ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ B \  \ \ \ \ C \ \ \ \ \ \ T\\J = \left \  NYC} \atop {LA}} \right.  \left[\begin{array}{ccc}{144}&{474 }&{274}\\{598}&{572}&{302}\\\end{array}\right]

The  number of each items made in the month of February[F] is  

 .\ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ B \  \ \ \ \ C \ \ \ \ \ \ T\\J = \left \  NYC} \atop {LA}} \right.  \left[\begin{array}{ccc}{ 424}&{492}&{546}\\{596 }&{530}&{164}\\\end{array}\right]

Generally given that the production for March of all products at all locations was the average of the January and February production then the number of each items made in the month of March[M] is

    .\ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ B \  \ \ \ \ \ \ \ \ \ \ \ \ C \ \ \ \ \ \ \ \ \ \ \ T\\M = \left \  NYC} \atop {LA}} \right.  \left[\begin{array}{ccc}{\frac{144 +424}{2}}&{\frac{474 +492}{2}}&{\frac{274 +546}{2}}\\{\frac{598 +596}{2}}&{\frac{572 +530}{2}}&{\frac{302+164}{2}}\\\end{array}\right]

=> .\ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ B \   \ \ \ \ \ C \ \ \ \ \ T\\M = \left \  NYC} \atop {LA}} \right.  \left[\begin{array}{ccc}{284}&{483}&{410}\\{597}&{551}&{233}{2}}\\\end{array}\right]
