Answer:
x = 6
Step-by-step explanation:
15 more represents “+15”
3 times a number represents “3*x” which is written as “3x”
So fifteen more than 3 times a number is 33 would be written as;
3x + 15 = 33
Now solve for x using algebra;
3x = 33 - 15
3x = 18
x = 18 / 3
<u>x = 6</u>

Answer:
D) AB = AB
Step-by-step explanation:
The reflexive property states that a value is equal to itself: x = x.
The reflexive property of length states that a length is equal to itself:
AB = AB
A) and C) are wrong. They represent the reflexive property of angles.
B) is wrong. It represents the symmetric property of length.
Answer:
The angle measures are 53.5° and 36.5°.
Step-by-step explanation:
We can create a systems of equations, assuming x and y are the angle measures.
Since the two angles are complementary, their angle measures will add up to 90.
x + y = 90
x - y = 17
We can now use the process of elimination, and end up with:
2x = 107
Dividing both sides by two gets us
x = 53.5
Substituting this value into an equation will get us y
53.5 + y = 90
y = 36.5

Answer:
Sample relative risk is 10.
Step-by-step explanation:
We are given the following in the question:
Group 1 of coal miners: 30 out of 150 get lung cancer.
Group 2 of non-coal miners: 5 out of 250 get lung cancer
Sample relative risk:
- It is the ratio of probability of an outcome in an exposed group to the probability of an outcome in an unexposed group.
Sample relative risk =
Thus, sample relative risk is 10.
