Answer:
0.525 = 52.5% probability that the two are from different families.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, the order in which the two participants are selected is not important, so we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
1 from the Harfield family(from a set of 7).
1 from the McCoy family(from a set of 9). So
Total outcomes:
2 from a set of 16. So
Probability:
0.525 = 52.5% probability that the two are from different families.

Answer:
The number for the given statement is 4
Step-by-step explanation:
Given as :
The statement is written as
<u>A number to the 11th power divided by the same number to the 8th power equals 64.</u>
Let the number = n
So, As per statement
= 64
Now, from the indices method
I.e if the base of the indices are same then the power are subtracted
So, Here the base is n and the power is 11 , 8
So, this can be written as
= 64
Or, n³ = 64
I.e n = ∛64
So, The cube root of 64 is 4
So, number = n = 4
Hence The number for the given statement is 4 Answer
To find the value of the angle we start with tan(theta)= o/a now fill in variables tan(theta)= 39.05/18 then we have to move tan to the other side so we get theta = tan^-1(39.05/18) this will give us theta = 65
90/100=0,9
0,9x100= 90% in favor
