Answer: D. This variable is a discrete numerical variable that is ratio-scaled.
Step-by-step explanation:
A Discrete variables are variables which are countable in a finite amount of time. For example, you can count the amount of money in your bank wallet, but same can’t be said for the money you have deposited in eveyones bank account as this is infinite.
So the number of times an individual changes job in a five years period is a perfect example of a discrete numerical variable that is ratio scaled because it can be counted.
Answer:
1. Because a right angle is 90 degrees, the answer to this is 90 - 65 = 25.
2. This question is similar to the last one, but this time the angle is 180 degrees total, so the answer is 180 - 55 = 125.
3. I'm fairly certain the lines here indicate that all three angles are the same. If all three angles make 180 degrees, the answer would be 180 / 3 = 60.
4. This is the same as in question 2. 180 - 135 = 45.
5. Again, because all three angles need to make up 180 degrees, we can just simply do 180 - (65 + 45) = 70.
6. With a quadrilateral, the angles add up to 360 degrees. We can do the same thing as in question 5 here. 360 - (70 + 95 + 55) = 140.
7. I don't remember exactly how to solve this but 55 degrees is correct because 55 + 55 + 70 = 180 which is the only possible value.
I haven't done this kind of stuff in a looooong time so I hope this suffices! :)
To calculate this you need to imagine triangle which points are:
boat
Top of lighthouse
Bottom of lighthouse
That triangle has 90 degrees angle at bottom of lighthouse. That means that we can use trigonometry to determine length between boat and bottom of lighthouse
tan(25) = 89/x
x = 89/tan(25)
x = 190.86
after rounding, the answer is D, 191 feet
Step-by-step explanation:
Any positive number can. be a side length. It cannot pass 7 because a square with 49 sqr lnches as a area has side lengths with the measures of 7.

Answer:
x + 3y = 21
Step-by-step explanation:

Equation of the line: y =mx+ b

Multiply the equation by 3
3y = -x + 21
x + 3y = 21
