Fifteen more than 3 times a number is 33. What is the equation and solve
kati45 [8]

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>

Hope this helps!

Which of the following represents the reflexive property of length? Question 6 options: A) m∠A = m∠A B) If AB = CD, then CD = AB
poizon [28]

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.

The difference of two complementary angles is 17 degrees. find the measures of the angles
ryzh [129]

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

Hope this helped!

Someone has conducted a study to see if there is increased risk of getting lung cancer if you work in a coal mine. In group 1, 3
AleksandrR [38]

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.

\text{P(Lung cancer for coal miner)} = \dfrac{30}{150} = \dfrac{1}{5}

Group 2 of non-coal miners: 5 out of 250 get lung cancer

\text{P(Lung cancer for non-coal miner)} = \dfrac{5}{250} = \dfrac{1}{50}

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 =

\dfrac{\text{P(lung cancer for coal miner)}}{\text{P(lung cancer for non coal miner)}}\\\\=\dfrac{\frac{1}{5}}{\frac{1}{50}} = \dfrac{50}{5} = 10

Thus, sample relative risk is 10.
