You answer is 12 because that is where on the graph it is the most constant
Answer:
to do this we have to divide 43 by 83
0.51807228915
so the frequency is about 51.8%
The best way to solve this problem is with a simple equation: part = percent (in decimal form) x whole
In this problem, we're trying to solve for the <em>whole </em>amount that the camera can hold, so we'll assign that the variable w.
We can use the information they gave us - 96 is the <em>part</em>, and 24% is the percent. We'll convert that to decimal form - 0.24
Then, we just plug these values back into the above equation:
96 = 0.24w
Divide both sides by 0.24 to get w on it's own, and you have your answer!
400 = w
Therefore, the memory card can hold up to 400 pictures.
Note: this equation is <em>super </em>helpful. It's good to have on hand for any problem involving percents, because you can solve for the part, percent, or whole depending on the problem.
Answer: The oldest one is Vredfort Crater.
Step-by-step explanation:
The data is:
Chicxulub was formed 6.5x10^7 years ago.
Vredfort was formed 2x10^9 years ago.
Sudbury basin was formed 1.8x10^9 years ago.
Acraman crater was formed 5.8x10^8 years ago.
We want to find the oldest, so we need to find the larger number of the 4 we have.
For this, we need to see at the exponents, the larger the exponent the larger the number.
We have two with a 9 in the exponent:
Vredfort and Sudbury.
Now we look at the number, Vredfort has 2x10^9 and Sudbury has 1.8x10^9.
Both have the same exponent, but the scalar of Vredfort is larger (2 is greater than 1.8) so we have that Vredfort is older.
