H(m ) = 3 + 10m
H(m ) = 2 + 12m
H(m ) = 10 + 3m
H(m ) = 12 + 2m
H(m ) = 3 + 10m
H(m ) = 12 + 2m
H(m ) = 10 + 3m
Answers
Answer:
The equations for the growth of two type of species are
H(m) = 12 + 2m
H(m) = 10 + 3m
Step-by-step explanation:
As given
The growth rate of two species of plants.
Species A is 12 cm tall and grows 2 cm per month.
The height of each species is represented by H(m) as a function of months m.
Than the equation becomes
H(m) = 12 + 2m
As given
Species B is 10 cm tall and grows 3 cm per month.
Than the equation becomes
H(m) = 10 + 3m
Than the equations for the growth of two type of species are
H(m) = 12 + 2m
H(m) = 10 + 3m
H(m) = 10 + 3m

1. You find, that the number 9.2 is 100% - because it's the output value of the task.
2. You need to find out what x is.
3. If 100% equals 9.2, you can write it down as 100%=9.2.
4. Now you know, that x% equals 43.7 of the output value, so we can write it down as x%=43.7.
5. Now you have two simple equations:
1) 100%=9.2
2) x%=43.7
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=9.2/43.7
7. Solution for 43.7 is what percent of 9.2
100%/x%=9.2/43.7
(100/x)*x=(9.2/43.7)*x - you multiply both sides of the equation by x
100=0.210526315789*x - you divide both sides of the equation by (0.210526315789) to get x
100/0.210526315789=x
475=x
x=475
So the answer is 475%! Hope it works!

Answer:
To solve for the variable "k" in the equation "k + 31 = 72," you need to isolate "k" on one side of the equation. Here's how you can do it using friendly words and reasons:
1. Start with the original equation: "k + 31 = 72."
2. To isolate "k," you want to get rid of the "31" on the left side of the equation. You can do this by subtracting 31 from both sides to keep the equation balanced.
3. Subtract 31 from both sides:
"k + 31 - 31 = 72 - 31."
4. Simplify both sides:
"k = 41."
Step-by-step explanation:
So, the correct equation to solve for the variable "k" is: "k = 72 - 31," and this will give you the value of k, which is 41.

Sample mean x bar = 1511.4 pages
Std deviation =s= 35.7 pages
Sample size n = 40
By assuming random samples since only sample std dev is know we can say that sample mean x bar follows a t distribution with
mean =1511.4 and std error =
Test statistic t = Mean diff/STd error = 1.613

A fraction is a short way to write a division problem.
Whenever you see a fraction, it means
(the top number) divided by (the bottom number).
When you pick up your pencil or your calculator and actually do the
division, the answer to the division is the decimal form of the fraction.
To change that fraction 1/5 to a decimal, divide 1 by 5 .
Then, to change the decimal to a percent, move the
decimal point 2 places that way ==>.
