Answer:
y= 12x^3-5x
y=2x^2+x+6
Step-by-step explanation:
To build an equation system, make both sides of the given equation equal to the same variable.
Let y be the variable. The equation 12x^3 - 5x = 2x^2 + x + 6 thus becomes 12x^3 - 5x = y = 2x^2 + x + 6.
As a result, the equation system becomes
Answer:
Step-by-step explanation:
This is a permutation problem. There are 5 swimmers in the race, and any combination of 3 will finish in the first 3 places. The formula will look like this:
₅P₃ = 
which will expand to
₅P₃ = 
and when the 2 * 1 cancels out between the numerator and the denominator, you're left with simply:
₅P₃ = 5 * 4 * 3
which is 60

Answer: There are 198 different combinations.
Step-by-step explanation:
To solve this type of problem, first, we need to identify the selections.
We have 3 selections.
Baby doll, Jigsaw puzzle, and a stuffed dog.
Now, we need to count the numbers of options for each case:
Baby doll: 11 options.
Jigsaw Puzzle: 6 options.
Stuffed dog: 3 options.
To find the total number of different combinations, we need to multiply all the numbers of options together, this is:
Combinations = 11*6*3 = 198
There are 198 different combinations.
Standard Normal Distribution. As discussed in the introductory section, normal distributions do not necessarily have the same means and standard deviations. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution.
