Answer:
2
Step-by-step explanation:
(-2 , 1) ; (1, 2.5)
Slope = 
![\frac{2.5-1}{1-[-2]}\\\\= \frac{1.5}{1+2}\\\\=\frac{1.5}{3}\\\\= 0.5](https://tex.z-dn.net/?f=%5Cfrac%7B2.5-1%7D%7B1-%5B-2%5D%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B1.5%7D%7B1%2B2%7D%5C%5C%5C%5C%3D%5Cfrac%7B1.5%7D%7B3%7D%5C%5C%5C%5C%3D%200.5)
m =0.5
y -y1 =m(x -x1)
y - 1 = 0.5(x - [-2])
y - 1 = 0.5(x + 2)
y -1 = 0.5x + 0.5*2
y - 1 =0.5x + 1
y = 0.5x + 1 + 1
y = 0.5x + 2
y-intercept = 2
Choice d because solid dot means or equal to and greater means to the right
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.
The most reasonable answer would be H.
Answer:
The answer to your question is:
1) x = 4
2) x = -2
Step-by-step explanation:
a) (x-3)² = x^{2} - 10x +25
x² - 6x + 9 = x² - 10x + 25
10x - 6x = 25 - 9
4x = 16
x = 4
b)
(x+4)³ = x³ + 12x² - 16x
x³ + 3(x²)4 + 3x(16) + 4³= x³ + 12x² - 16x
x³ + 12x² + 48x + 64 = x³ + 12x² - 16x
48x + 64 = 16x
48x - 16x = -64
32 x = -64
x = -64/2
x = -2
