The average atomic mass is 6.92X
How do we compute the average atomic mass?
In a bid to calculate the average atomic mass, we multiply the fraction of each isotope by the mass number , then add them together.
This is more like weighted average, as shown below:
average atomic mass=(mass number of first isotope*fraction)+(mass number of second isotope*fraction)
average atomic mass=(6X*7.59%)+(7X*92.41%)
average atomic mass= 6.92X

Since the intersection is - by definition - common to both sets, we can work out the number of people that use only the fitness suite or the swimming pool.
We know that 57 people use the fitness suite, but 36 of those are already counted in the intersection. So, 57-36=21 people use only the fitness suite.
The same goes for the swimming pool: 49-36=13 people use only the swimming pool.
So, we have:
- 21 people using fitness suite only
- 13 people using swimmng pool only
- 36 people using both
This sums to 21+13+36=70 people. We deduce that 30 people don't use any of the features.
The first step is to add 5.2 to both sides.
Step-by-step explanation:
There should be an option that says, “From the origin, move 0.5 unit to the right along the x-axis and 1 unit down, and place the point.”
To form the <u>converse</u> of the <u>conditional statement</u>, interchange the <u>hypothesis</u> and the <u>conclusion</u>.
Given conditional statement: "if two angles are both obtuse, the two angles are equal".
Here,
- hypotesis is: two angles are both obtuse,
- conclusion is: two angles are equal.
Then the converse statement will be: "If two angles are equal, then two angles are both obtuse".
