T is equal to 21, because 1/3 of 21 is equal to 7. To get this answer all you have to do is multiply 7 by 3 to get 21.
Answer:
1.)
P(E) = 0.5
P(A) = 0.2
P(N) = 0.3
Conditional probability ;
0.47
Step-by-step explanation:
Let :
E = Excellent ; A = Average ; N = not up to standard
P(E) = 0.5
P(A) = 0.2
P(N) = 0.3
If Leo shows up ; this type of probability is called a conditional probability. It is the likelihood of an event based on a certain or already satisfied condition.
The probability that Leo is coming :
Leo ; Excellent = 0.7
Leo ; Average = 0.3
Leo; Not up to standard = 0.2
Hence, probability they Leo is coming :
(0.5 * 0.7) + (0.2 * 0.3) + (0.3 * 0.2)
0.35 + 0.06 + 0.06
= 0.47
Answer:

Explanation:
The figure is a right triangle with:
- hypotenuse = segment AC
- vertical leg = 7 units
- horizontal leg = 4 units
Hence, you must use Pythagora's theorem, which is valid for all right triangles:

Substituting the data:

Square root both sides:

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.
