<u>Answer: </u>

Temperature was 19 degree warmer in New York compare to temperature in Montreal.  

<u> Solution: </u>

Given information is as follows  

Temperature in Montreal = -8  

Temperature in New York = 11

Need to find by how much degree the temperature was warmer in New York.

degree by which temperature was warmer in New York compared to Temperature of Montreal is equal to (Temperature in New York) – (Temperature in Montreal)

= 11 – (-8)  = 11 + 8 = 19

Hence temperature was 19 degree warmer in New York compare to temperature in Montreal.

Hello ya'll. I have a quick question to ask ya'll.
stepladder [879]

Answer:

3n

Step-by-step explanation:

If the initial number is n, one less than n is n - 1, and one more than n is n + 1. so we have:

n - 1 + n + n + 1=3n

At first I thought this answer was too easy, so I tried for n is 6.

3*6=18\\5+6+7=18

This is really cool! Hope this helps!

the sum of three numbers is 2100. the first number x is equal to the sum of the other two (y and z) which are equal to each othe
max2010maxim [7]
We will have a system of equations, and we are going to solve it by using substitution.
Let's make the equations.
x+y+z=2100
z+y=x
Since y and z are equal, I think it is easier for us to have them as one variable for now. Let the value of z and y be a.
These are the equations now.
x+2a=2100
2a=x
Since the second equation is giving the value of x, let it replace the value of x also in the first equation.
2a+2a=2100
4a=2100
2100÷4= 525
so, x and y equal 525. Let's put this in our original equation.
x+525+525=2100
x+ 1,050= 2,100
x= 1,050
So, x=1,050, y= 525 =z.

Answer:

a. The Venn diagram is explained in the attached word file.

0.61                                    

b. Not independent

Step-by-step explanation:

a. The hypothetical 1000 table for given situation is

                                          Adult(A)        Not Adult (not A)        Total

Travel outside (T)                 610                170                               780

Not Travel outside (not T) 110                110                               220

Total                                 720                280                               1000

P(Adult and travel outside)=P(A and T)=610/1000=0.61

b. Multiplication rule for independent events is

P(A and B)=P(A)*P(B)

P(A and T)=0.61

P(A)*P(T)=0.72*0.78=0.56

As P(A and T) is not equal to P(A)*P(T), so event "being an adult" and "travel outside" are not independent.

You can find the area of the rectangle and the triangle separately and then add them together which would result in 330in. I personally do not think you should use the trapezoid formula even though they said it is a trapezoid (a trapezoid is usually not shaped like that) but if you want to it would result in 270in.
