Answer:
Option C is correct. Option f is the same as option C
Step-by-step explanation:
From the question, There are three high schools in the district, each with grades between nine to twelve. The school board decided to pool all of the students together and randomly samples 250 students in the whole district that has schools between the grade of nine to twelve.
In order to test for high school students in the district for Attention Deficit disorder(ADD), they could have chosen any 250 students from any school with grades betweem nine to twelve throughout the district.
The equation for density is:
To help you remember - my teacher told us to remember "We <span>♡ density," and the heart stands for </span>
, or
. Cheesy, but it works!<span>
</span>
Back to the problem:We know the mass if 49g and the volume is 7
, so plug these values into the equation for density:
Answer: The density is 7 g/
Suppose U= {1, 2, 3, 4, 5, 6, 7, 8} is the universal set and P= {1, 2, 3, 4}. What is P?
Digiron [165]
Did you mean P' ? The letter P with a tick mark after it. If so, then start with set U and erase any number you find in set P
We start with
{1,2,3,4,5,6,7,8}
and we erase the following: 1,2,3,4
since those numbers are in set P
P = {1,2,3,4}
P ' = {5, 6, 7, 8}
<span>The set P' is the complement of set P. It is, in a sense, the opposite of set P. It contains everything that P doesn't have.</span>
Answer:
B
Step-by-step explanation:
Just make sure that the x value is not being repeated twice. because one of the given points is (4,9) you cannot have the point (4,0). X value cannot repeat in a valid function.
Answer: B: (1-5x²)³, all real numbers
Step-by-step explanation:
The notation 
is called function composition, which is where you pass one function in as the value of another function. In other words, 
.
Since we have the values for f(x) and g(x), let's plug them in.
Hence, the best answer choice is B, as all real numbers would work and it is the cube of 1 - 5x².
