Answer:
72/97
Step-by-step explanation:
take angle c as reference angle
to find sin c
sin c = opposite / hypotenuse
sin c = 72 / 97
Answer:
37°
Step-by-step explanation:
As we know the sum of angles of a triangle is 180 degrees.
Therefore,
angle A + angle B + angle C = 180°
In the given picture two angles are given and we have to find out the third angle.
x° + 45° + 98° = 180°
x° + 143° = 180°
x° = 180° - 143°
x° = 37°
The value of x in the triangle shown is 37°.
Answer:
Real part = 3 & imaginary part = 1
2) 4 + 7i - 8 = 4 -8 + 7i
= -4 + 7i
Real part = -4 & imaginary part = 7
Real part = -2 & imaginary part = -5
b) 1) 6 + 4i
2) -12+ 5i
3) 5-14i
Answer:
Step-by-step explanation:
Hello!
The variable of interest is:
X: Number of people in Casperville that own a landline out of 100 people.
There is a fixed number of surveys made (trials) n=100, for each trial there are two possible answers, "success": the person owns a landline, and "failure": the person doesn't own a landline. Assuming each person is independent of the others and that the probability of success is the same for all trials, we can say that this variable has a binomial distribution: X~Bi(n;p)
To estimate the proportion/ percentage of people in Casperville that owns a landline you have to calculate the sample proportion:
^p=
6% of the people surveyed owns a landline.
I hope this helps!
