Answer:
X= 12
Step-by-step explanation:
Simplifying
4x + -2 = 46
Reorder the terms:
-2 + 4x = 46
Solving
-2 + 4x = 46
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + 4x = 46 + 2
Combine like terms: -2 + 2 = 0
0 + 4x = 46 + 2
4x = 46 + 2
Combine like terms: 46 + 2 = 48
4x = 48
Divide each side by '4'.
x = 12
Simplifying
x = 12
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Number of colors that the arrow can land on = 8
We need to find the degrees of freedom for a goodness of fit test of the fairness of this spinner.
As we know that degree of freedom is 1 less than the size of sample.
So, Mathematically, it is expressed as below:
So, Degree of freedom would be

Hence, Option 'c' is correct.
Answer:
-21
Step-by-step explanation:
3t-7=5t
-7=5t-3t
-7=2t
t= -7/2
6t=?
6(-7/2)= -21
1.1x=17.85
x=16.227272727272727...
Round to $16.23
