Answer:
The second graph in the upper line.
Step-by-step explanation:
We have been given an inequality . We are asked to find the graph of the given inequality.
Since our inequality has a greater than or equal to sign, so the boundary line of inequality would be solid line.
The boundary line would be vertical line passing through the x-axis at point .
Now, we will test point (0,0) to find the shaded area.
Since point (0,0) doesn't satisfy the given inequality, so shaded area of the given inequality would be area excluding point (0,0).
Therefore, option B is the correct choice.
Step-by-step explanation:
☄ The ratio of new houses to antique houses in a village is 4 : 5 . If there are 12 new houses , how many antique houses are there ?
☄
✏ Let , the number of antique houses in a village be ' x ' .
Then , According to the question :

Answer:
a) 0.0523 = 5.23% probability that at least two of the four selected will turn to be no-shows.
b) 0 is the most likely value for X.
Step-by-step explanation:
For each traveler who made a reservation, there are only two possible outcomes. Either they show up, or they do not. The probability of a traveler showing up is independent of other travelers. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
No-show rate of 10%.
This means that
Four travelers who have made hotel reservations in this study.
This means that
a) What is the probability that at least two of the four selected will turn to be no-shows?
This is
In which
0.0523 = 5.23% probability that at least two of the four selected will turn to be no-shows.
b) What is the most likely value for X?
X = 0 has the highest probability, which means that 0 is the most likely value for X.
Answer:
D2=21/24 mile
Step-by-step explanation:
Her it is not specified if it is base or height, it only talks about dimensions, so let's work with dimensions
A=1/12
D1=4/21mile, D2=?
Area of a triangle
A=((D1*D2)/2) → 2A=D1*D2 → D2=2A/D1 so D2=(2*1/12)/(4/21) =(1/6)/(4/21) = (1*21)/(6*4)=21/24 mile
