Answer:
Step-by-step explanation:
well, by using definition of tan of an angle
let the distance between Earth and shooting star is 
.
since 
,
then 
Given, a = -65 and b = 8.
We have to find multiplication of them.
a is negative and b is positive. When we multiply them, we know that the multiplication of positive and negative is negative. That means 
.
So 
= 
= 
= 
So we have got the required product.
Multiplication of a and b = -520.
The correct option is option C.
Answer:
55
Step-by-step explanation:
20% is the same as 1/5, so we can multiply 11 by 5:
11*5=55
Answer:
If the committee must consist at least one student, the probability is 99.96%
Step-by-step explanation:
Given;
number of teachers = 5
number of students = 20
Total number of committee members = 25
Possible outcome of all the members in the 4 committee = 25C₄ ways
= 12650
If the committee must consist at least one student, then the possible outcome;
= Total possible outcome - committee with no student
= 25C₄ ways - 5C₄ ways (all committee members are teachers)
= 12650 - 5
= 12645
The probability that the committee will consist at least one student;
= 12645 / 12650
= 0.9996
= 99.96%
Therefore, if the committee must consist at least one student, the probability is 99.96%
5400*0.04(rate)=216
Because it's simple interest for 7 years, 216*7 should be the answer
So $1512
