Answer:
120
Step-by-step explanation:
Here, we want to get the possible value of A
Now, we should understand that the value of an angle in triangle cannot be more than 180
Also, cosine can only be negative in the second and the 3rd quadrant
So,
arc cos (-0.5) = 120 , 300 , 60
But 60 is not correct as it will give a negative value
300 is not correct also as it is more than the angles present in a triangle
Thus, our answer is 120
Answer: Population
In statistics, a population is the entire group of people you want to determine some fact about (eg: average height). A sample is a subset of the population that should ideally represent the population.
Answer:
1)Add 19
2)Multiply by 5
Step-by-step explanation:
Adding 19 to both sides.
Multiplying 5 to both sides.
∴
Try 18 and then multiply the sum of 2 and 18 to 7
You can find the x and y intercepts by plugging 0 in for each of the variables
(0)=-7x-1
1=-7x
x=-1/7
your x- intercept is (-1/7,0)
y=-7(0)-1
y=-1
your y-intercept is (0,-1)
