<span>an observational study because it involves the pre-existing condition of the subjects</span>
Nikitich [7]3 years ago
3 0

Answer:

An observational study

Step-by-step explanation:

When an observational study is done, the individuals are observed but there aren't any attempts to modify their conduct or to manipulate a variable.  There is no treatment given but the simply observation of the subjects who are selected because of certain characteristics.

In this case, an observational study should be helpful because the people have already a pre-existing condition of being exposed to radiation and therefore, the effects on their health can be studied without any new treatments or scenarios.

What is the probability of getting an odd number on a fair die and a tail on a coin flip?
Leokris [45]
Odd number on a fair die:
50%, as 1,3,5 are all odd and there are 6 sides on a die
tails: 50% as 2 sides.
But if you are asking together: for each possible side on the die, there is a possibility of heads or tails
1: H T
2: H T
3: H T
4: H T
5: H T 
6: H T
so 12 possibilities.
to roll an odd number and have a coin land on tails
1: T
3: T
5: T
3 different possibilities satisfy that
so then the answer becomes: 3/12
so 25%

A right triangle has a hypotenuse of 10 mi. and a leg of 6 mi., what is the length of the other leg?
slava [35]

Answer:

8mi

Step-by-step explanation:

Using Pythagoras theorem

Hypotenuse square = opposite square + adjacent square.

Let the other leg be x

10 square = 6 square + x square

100 = 36 + x square

Collect like terms

X square = 100 -36

X square = 64

Find square root of both sides

X = square root of 64

X =8mi

Solve for x. Round to the nearest tenth, if necessary....pleaseeeee help me with this lol.
insens350 [35]

Based on the information given, it has been calculated that they value of x will be 0.9646.

<h3>Solving triangles</h3>

Based on the information given, it should be noted that the sine formula will be used.

Therefore, the equation to solve the question will be:

Sin 16° = x/3.5

x = Sin 16° × 3.5

x = 0.2756 × 3.5

x = 0.9646

What is the difference between 5/6 and 1/5
Slav-nsk [51]

Hey there!

The answer is \frac{19}{30}

To solve this we use subtraction, because "the difference" represents subtraction, so:

\frac{5}{6} - \frac{1}{5}

Now, we must find a common denominator, and we can see that 6 and 5 both go into 30. To get to 30, we multiplied the first fraction by 5 and the second by 6, so we now have:

\frac{25}{30} - \frac{6}{30}

This is equal to \frac{19}{30}

Hope it helps and have a great day!
