Answer:
Continues variables
Step-by-step explanation:
A continuous variable is the one that takes an exact value in a continuous range. Always between 2 observable values, there are going to exit a third intermedium value that the variable can take.
Answer:
a)There are 14 teachers in Ryan's sample, and 362 teachers in the population.
Step-by-step explanation:
<u> Population:-</u>
<em>The totality of observations with which we are concerned, whether this number be finite or infinite is called population.</em>
<em>Given data population is 376 teachers at a university were female'</em>
<u><em>Sample:-</em></u>
A sample is a subset of a Population
sample of given data = 14teachers
The percentage of 376 teachers at a university were female, Ryan randomly selected 14 teachers.
<em />
<em> = 3.72%</em>
Answer:
36 erasers
Step-by-step explanation:
Let number of erasers be e
let number of rulers be r
We can write:
e + r = 70
and
After giving away, he has
Erasers: 2/3e
Rulers: r - 10
These two are equal, so we can write and solve:
2/3e = r - 10
2/3e + 10 = r
Putting this in initial equation, we have:
e + (2/3e + 10) = 70
5/3e + 10 = 70
5/3 e = 60
e = 36
And rulers is:
r = 2/3(36) + 10 = 34
Hence, he had 36 erasers in the beginning
Answer:
n = 4
Step-by-step explanation:
3 + 4n + n = 2n +15
3 + 5n = 2n + 15
5n - 2n = 15 - 3
3n = 12
n = 12 / 3
= <u>4</u>
Answer:
A) y=5x+9 B) -5x+y=9
Step-by-step explanation:
y-y1=m(x-x1)
y-(-1)=5(x-(-2))
y+1=5(x+2)
y=5x+10-1
y=5x+9
y-5x=9
-5x+y=9
