9 trains headed north
5+4+9 = 18 trains total
P(north) = (# of north)/(# total) = 9/18 = 1/2
Find the mean absolute deviation (mad) for this data. (remember to show your 4 steps) 88, 72, 85, 76
Answer:
Step-by-step explanation:
mean=(88+72+85+76)/4=321/4=80.25
x |x-mean|
88 7.75 (88-80.25)
72 8.25 (80.25-72)
85 4.75 (85-80.25)
76 4.25 (80.25-76)

What is the congruence correspondence, if any, that will prove the given triangles congruent ?
Answer:
none.
Step-by-step explanation:
because FTP=ATJ,
P=A
J=F
The two triangles are not congruent. The correct answer is option A.
What is congruency?If two triangles are congruent, this means they are the same shape and the same size. By definition, all corresponding angles of two congruent triangles are congruent. Additionally, all corresponding sides of two congruent triangles are congruent.
In the image two triangles, ETP and ATJ are given. Angle F and angle J are equal due to the opposite angle property. Similarly, angle P and angle A are also equal by alternate angle property. But all the angles are not congruent.
Hence, the triangle FTP and ATJ are not congruent with each other.

Answer:
6. Not so clear
7. 72 degrees
8. 5x + 60 = 180
9. 15 degrees
10. C
Step-by-step explanation:
7. 4x + 12 + 3x + 4 = 121 So this is the equation for the whole angle ADC.
7x + 16 = 121 Collect like terms
7x + 16 - 16 = 121 - 16 Bring 16 to the other side of the equation
7x / 7= 105 / 7
x = 15
After finding the value of x substitute it into the equation for angle ADB thus:
4 ( 15 ) + 12 = 72 DEGREES
8. When those two angles meet they form an angle in a straight line thus they sum to 180 degrees.
9. So we already know of all angles except for 1 which is the one you need to find and what you simply do is:
Add 120 + 30 + 15 = 165
Then subtract 165 from 180 because they are angles in a straight line:
180 - 165 = 15 degrees
10. The answer is C because they are adjacent and they form a perpendicular.

Answer:
hope it helps u
Step-by-step explanation:
7y + 4x - 10 + 5y - 5 + x
= 7y+5y+4x+x–10–5
= 12y+5x–15
Answer:
12y + 5x - 15
Step-by-step explanation:

[tex]7y + 5y = (7 + 5)y = 12y[/tex]
[tex]12y + 4x - 10 - 5 + x[/tex]

The solution for 3.5 divided by 7 is,
⇒ 70
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The expression is,
⇒ 3.5 divided by 7
Now, We can write as;
⇒ 3.5 divided by 7
⇒ 3.5 ÷ 7
⇒ 35 / 70

Why is the absolute value of a positive integer a negative integer?
Answer:
Distance from zero.
Step-by-step explanation:
a good example would be this:
the absolute value of -8 is +8 because -8 is 8 units from zero on the number line.
with everything else, whenever you have a negative number and it's a negative integer, it'll always be negative, and whenever you're trying to switch from positive it'll always be plus.
I hope that makes sense!
Positive integer ( + 5, + 7, + 9 )
negative integers ( - 5, - 7, and - 9 )

14 - 10x = x+36
Answer:
Step-by-step explanation:
re arange the order
-10+14=x+36
then subtract 14 from both sides of the equation
−-10x+14-14=x+36-14
then simplify it
-10x=x+22
subtract x from both sides of the equation
-10x-x=x+22-x
simplify
-11x=22
subtract the 11 from both sides and simplify
x=-2

Answer:

Step-by-step explanation:
Divide the expression by two parts: the first one with all positive integer (the integer which can't be divided by two), 1+3+5+...2013 and the rest -2-4-6-...-2012
If you notice both parts are arithmetical sequences
Explore the first one 1+3+5...+2013
a1=1 d=3-1=2 an=2013
a1+d(n-1)=an
1+2(n-1)=2013
2(n-1)=2012
n-1=1006
n=1007
Sn=( 1/2)*(a1+an)*n= 0.5*2014*1007=1007*1007=1014049
-2+(-4)-...-2012
a1=-2
d=a2-a1= -4-(-2)=-2
a1+d(n-1)=an
-2+(-2)(n-1)=-2012
n=1006
Sn= (a1+an)/2*n=(-2-2012)/2*1006=-1007*1006
-1007*1006+1007*1007= 1007- the answer
The second mean
1-2=-1
3-4=-1
5-6=-1
There are 2012/2=1006 couples and every of them has sum -1
-1*1006=-1006
-1006+2013=1007

How do you identify the leading term and coefficient of a polynomial expression
Answer:
We can find the degree of a polynomial by identifying the highest power of the variable that occurs in the polynomial. The term with the highest degree is called the leading term because it is usually written first. The coefficient of the leading term is called the leading coefficient.
