1. 42 cards
2. 3/5 of his cards
Answer:
X = 4√3
Step-by-step explanation:
Using tangent-secant theorem
So,
X² = (4)(4+8)
X² = (4)(12)
X² = (48)
Taking sqrt on both sides
X = 4√3
Answer:
d) This is a completely randomized design with two explanatory variables (factors).
Step-by-step explanation:
Explanatory variables are independent variables.
In this case, I prepared two explanatory variables, which are : (i)30-second ad
(ii) 60-second ad,
Then, the explanatory variables were assigned to 4 treatment groups, and each variable is done once or thrice.
All subjects are assigned randomly to all treatment groups, with each treatment group seeing one. We can conclude that this is a completely randomized design with two explanatory variables.
Outcome - <span>one of the mutually exclusive results of an activity
probability - </span><span>a measure of likelihood of a given result
compound events - </span><span>events involving two or more activities
event - </span><span>a combination of one or more outcomes
independent events - </span>compound events whose outcomes do not affect each other
conditional probability - <span>probability of one event given that another has occurred</span>
Answer:
4 units.
Step-by-step explanation:
As its a tangent to the y axis the radius is 0 - (-4) = 4 units.
