Step-by-step explanation
- Let x be the number of adults and y the number of kids
We can then write this two equations :
x+y= 33
15x+7y= 311
- let's solve the two eaquations
to do that we should combine them both in a way that help us get rid of one of the variables.
Let's multiply the first equation by -7 to get rid of y by adding it to thr second equation
-7x-7y= -231
now add both equations .
15x+7y-7x-7y=311-231
we get : 8x = 80
as you notice y is gone and we get a classic easy equation to solve
x= 80/8
= 10
so the number of adults is 10
let's go back to the first equation ( x+y= 33) and replace x with 10
10+y= 33
y= 33-10
=23
let's check using the second equation :
(10*15)+(23*7) = 311
that is true
so :
- the number of adults is 10
- the number of kids is 23
Answer:
18.75%
Step-by-step explanation:
Hello,
3 students are both female and senior
the total number of students is 7+10+8+5=30
so the probability to select one female senior is 3/30=1/10=0.10
probability to select one female is 16/30=16/30
probability that the student is a senior given that it's female is
=P(female and senior)/P(female)
=1/10*30/16=3/16
hope this helps
The given polynomial has a degree of 4, the leading coefficient is 3, and the constant is 4.4.
<h3>What is a polynomial?</h3>
A polynomial is an algebraic expression with terms that are the combination of variables, coefficients, and constants.
- The highest power of the variable is said to be the degree of the polynomial.
- The coefficient of the highest power variable is said to be the leading coefficient.
<h3>Calculation:</h3>
The given polynomial is
g(x) = 13.2x³ + 3x⁴ - x - 4.4
The highest power of the variable x is 4. So, the degree of the variable is 4.
Then, the leading coefficient is 3.
The constant on the given polynomial is 4.4.
