Answer:
Step-by-step explanation:
First, you need to divide everything by 6.
Then you put everything in a radical to get this:
I think it’s 4.308 when u multiply
Number 1: (-1+2i)+(6-9i)
Number 2: (3-3i)-(4+7i)
Number 3: (-5+2i)+(-2+8i)
Answer:
Option C and D are false
Step-by-step explanation:
All the mentioned option are correct in the given scenario except option C and D.
The reason is that dose is categorized as nil, low and high so, dose is categorical variable. Also, number of tumors is quantitative variable because it can be meaningfully interpreted in numerical form. The number if tumors is discrete quantitative variable.
Now consider all options
A) Gender is categorical ; dose is ordinal
This option is true because gender can be categorized into male and female and also dose is ordinal because it has order i.e. nil,low and high.
B) Gender is discrete; weight is continuous
This option is false because gender can be a discrete variable and weight is continuous variable because it is measurable. So, the statement is true.
Option C and D are already discussed an option E is discussed in option B.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -15 ± √((15)^2 - 4(2)(4)) ] / ( 2(2) )
x = [-15 ± √(225 - (32) ) ] / ( 4 )
x = [-15 ± √(193) ] / ( 4)
x = [-15 ± sqrt(193) ] / ( 4 )
x = -15/4 ± sqrt(193)/4
The answers are -15/4 + sqrt(193)/4 and -15/4 - sqrt(193)/4.
