Answer:
the anwser is 95 dollars I know because i did this
<span>So we have a cube with sides numbered form 1 to six and we want to know what is the experimental probability of rolling either a 3 or a 6. So the probability of rolling any number from 1 to six is 1/6 because a cube can fall only on one side. But we need either 3 or a 6 so the probability of the cube falling on a side we want is double of 1/6 and that is 2/6=1/3.</span>
Answer: a) Required minimum sample size= 219
b) Required minimum sample size= 271
Step-by-step explanation:
As per given , we have
Margin of error : E= 5% =0.05
Critical z-value for 90% confidence interval :
a) Prior estimate of true proportion: p=28%=0.28
Formula to find the sample size :-
Required minimum sample size= 219
b) If no estimate of true proportion is given , then we assume p= 0.5
Formula to find the sample size :-
Required minimum sample size= 271
Answer:
The greatest possible value of xy is 165.
Step-by-step explanation:
Answer:
The answer to your question is below
Step-by-step explanation:
sin Ф = Opposite side / hypotenuse
cosФ = Adjacent side / hypotenuse
tan Ф = Opposite side / Adjacent side
For this right triangle
Opposite side = 5
Adjacent side = 12
Hypotenuse = 13
Then,
sin Ф = 5/13
cos Ф = 12/13
tan Ф = 5/12
