Nothing random about 19, he's generating the terms with a sequence
20.) 12, actually lcm (4,3)=12
21.) 35, 7*5=35
22.) all multiples of 28
=1*28 (1 box of 28/ 28 boxes of 1)
=2*14 (14 boxes of 2/ 2 boxes of 14)
=4*7
actually 28=2^2 * 7 by Fundamental Thm of Arithmetic
2*2*7
2*14
4*7
28*1
so there are 4 ways depending on how you arrange boxes and crayones, excluding 1,28

Hypothesis: Family centered care is a significant predictor of children's health-related quality of life, independent of illness
Nostrana [21]

Answer:

This hypothesis is a Directional Hypothesis.

Step-by-step explanation:

Family centered care is a significant predictor of children's health-related quality of life, independent of illness severity.

This hypothesis is a Directional Hypothesis.

Directional hypothesis predicts the way in which the independent variable will affect the dependent variable.

Here, independent variable is - family centered care

Dependent variable is - health related quality of life

We can see that when family centered care is of great quality, there is no severe illness for children.

Write the equation using function notation f(x). then find f(0)<br><br> 2x^2 - 3y = 6
Grace [21]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \: f(0) = -2

____________________________________

\large \tt Solution  \: :

\qquad \tt \rightarrow \: 2 {x}^{2}  - 3y = 6

\qquad \tt \rightarrow \: 3y + 6 = 2 {x}^{2}

\qquad \tt \rightarrow \: 3y = 2 {x}^{2}  - 6

\qquad \tt \rightarrow \: y =  \cfrac{2 {x}^{2} - 6 }{3}

\qquad \tt \rightarrow \: y =  \cfrac{2 {}^{} }{3}  {x}^{2}  - 2

[ here, y can be replaced with f(x) because y is a function of x ]

\qquad \tt \rightarrow \: f(x) =  \cfrac{2 {}^{} }{3}  {x}^{2}  - 2

\large\textsf{Find f(0):}

\qquad \tt \rightarrow \: f(0) =  \cfrac{2 {}^{} }{3}  {(0)}^{2}  - 2

\qquad \tt \rightarrow \: f(0) =  0  - 2

\qquad \tt \rightarrow \: f(0) =   - 2
