First off, let's find out the growth rate per century in millimeters.
Since there are are one hundred days in a century, we just have to multiply 0.35 by 100. We just have to move the decimal point two places to the right to receive a rate of 35 mm per century. We can use a mm to ft conversion calculator to convert 35 mm to feet- getting 0.1 (rounded to the nearest tenth.
So this growth rate is 0.1 feet per century. Hope that helped!
Answer:
If the soccer coach wants to know how many students made 15 or more goals then she should use the histogram because it is split in to different ranges so it’s easy for her to know how many students made 15 or more goals. If the soccer coach wants to know the least number of goals made she should use the dot plot because that shows the specific number of goals each student made while the histogram only gives an range.
Using a calculator, inserting the values of x and y, the correlation coefficient for the given data-set is of -0.9422.
<h3>How to find the correlation coefficient of a data-set?</h3>
Using a calculator, the correlation coefficient is found inserting the ordered pairs (x,y) in the calculator.
In this problem, we have that:
- The values of x are: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5.
- The values of y are: 112.5, 110.875, 106.8, 100.275, 91.3, 79.875, 70.083, 59.83, 30.65, 0.
Hence, using a calculator, the correlation coefficient is of -0.9422.

144+64= 178
a^2+b^2= c^2
Whenever finding a missing length use the formula up above :
a^2+b^2= c^2
a^2-b^2= c^2
144-64= 80

Answer:
The equation that describes the amount of mass left after a time t of a radioactive isotope is the following:
where
is the mass of the sample at t = 0
is the half-life of the sample
For the element X in this problem,
We want to find the time t at which
So we need to re-arrange the equation making t the subject:
Step-by-step explanation:
