Answer:
I think there should be a picture for this, but since I don't see any, I will just explain visually.
On a number line, you would go 4 steps or bars to the left (since it is negative) and then since it is minus, minus, it would be the OPPOSITE of negative, which is positive. so you go from -4 to 6 steps to the right.
Step-by-step explanation:
Did you know that there is a easy way to know this?
If you see -(-, it looks like a plus (+), right?
Well, it is!! This is how I remember it, and it is the easiest and fun way to remember it. Remember, -(- is +.
So, the equation would be
-4 + 6.
To solve the answer, you can do 6 - 4. Since 6 is a positive and has a greater value, you would subtract 4 from it to get a positive number. 6 minus 4 is 2, so on the number line, you should end at positive 2.
Answer:
Standardized z score = 2.06
His house rent is not an outlier
Step-by-step explanation:
The mean monthly rent of students at Oxnard university is 970 with a standard deviation of 204. John`s rent is 1390. What is his standardized z-score? Is john`s rent an outlier? How high would the rent have to be to qualify as an outlier
We solve using z score formula
= z = (x-μ)/σ, where
x is the raw score = 1390
μ is the population mean = 970
σ is the population standard deviation = 204
His z score is calculated as:
z = 1390 - 970/204
z = 2.06
No his house rent is not an outlier
Step-by-step explanation:
given :
2x - 3y = 11
-6x + 8y = 34
find : the solutions of the system by using Cramers Rule.
solutions:
in the matrix 2x2 form =>
[ 2 -3] [x] [11]
=
[-6 8] [ y] [34]
D =
| 2 -3 |
|-6 8 |
= 8×2 - (-3) (-6)
= 16-18 = -2
Dx = | 11 -3 |
| 34 8 |
= 11×8 - (-3) (34)
= 88 + 102
= 190
Dy = | 2 11 |
|-6 34 |
= 2×34 - (-6) (11)
= 68 + 66
= 134
x = Dx/D = 190/-2 = -95
y = Dy/D = 134/-2 = -67
the solutions = {-95, -67}
