Answer:
the median will be 200.
the mode will be 402 n 398.
the mean will be 400.
Answer:
Step-by-step explanation:
Let the consecutive even numbers be 2n , (2n + 2) , (2n +4), (2n + 6)
2n + 2n+2 + 2n+4 + 2n+6 = 180
Add like terms
<u>2n + 2n + 2n + 2n</u> + <u>2 + 4 + 6</u> = 180
8n + 12 = 180
Subtract 12 from both sides
8n + 12 - 12 = 180 - 12
8n = 168
Divide both sides by 8
8n/8 = 168/8
n = 21
2n = 2*21 = 42
2n + 2= 2*21 +2 = 42 +2 = 44
2n +4 = 2*21 + 4 = 42 + 4 = 46
2n +6 = 2*21 + 6 = 42 + 6 = 48
The 4 consecutive even integers: 42, 44 , 46 , 48
Answer: 20 feet.
Step-by-step explanation:
Observe the right triangle attached.
You need to find the value of "x".
Then, you can use the Pythagorean Theorem:
Where "a" is the hypotenuse of the triangle, and "b" and "c" are the legs.
In this case, you can identify that:
Substitute these values into :
Now, you need to solve for x to find how far up the wall the top of the ladder reaches. Then you get:
Answer:

Answer:
Step-by-step explanation:
Algebraic expression: 4x - 2y
Algebraic equation: 4x - 2y = 15
Term(s): 4x, -2y
Coefficient(s); 4, -2
Constant(s); no constants
Variable(s): x, y
expressions don't have an equal sign, equations do
terms are separated by operational signs (multiplication, division, addition, subtraction)
Coefficients are the numbers before variables
Constants aren't variables
Variables are letters
