Okay let's write this out. 3z+a=10, where Zoey and Ayden are z and a respectively. a=2z

We can further simplify by substtitition.

3z+2z=10

5z=10

3(2) + a = 10

6+a=10

a=4

There are 21 students in a class. The median age of the students is 23. The oldest student is 29.

Varvara68 [4.7K]

Answer:

1) At least one (the 11th) student is 23 (years old), Must be true

2) Some students are younger than 15 Could be true

Step-by-step explanation:

1) The given parameters are;

The number of student in the class = 21

The median age of the student = 23

The age of the oldest student = 29

Therefore, given that the median age = The age of the (n + 1)/2 th student

Where;

n = The number of student in the class = 21

∴ The median age = The age of the (21 + 1)/2 th = 11 th student, when the age of the students are arranged in increasing order, therefore, we have;

At least one (the 11th) student is 23 (years old), Must be true

2) Given that there are 10 students with ages equal to or lower than the median age, and the difference between the median age and the age of the oldest student = 29 - 23 = 6 years, we have;

Some students are younger than 15 Could be true

Francisco has a savings account balance of 2,033.88. The interest rate on the account is 2.9% compounded monthly. If he opened t

inna [77]

Let P = the value of the initial deposit.

Given:
A = 2,033.88, the current amount
r = 2.9% = 0.029, interest rate
n = 12, compounding interval
t = 9 years

Then
$A=P(1+ \frac{r}{n})^{nt}$

That is,
P(1 + 0.029/12)¹⁰⁸ = 2203.88
1.2978P = 2203.88
P = $1,698.17

Answer: $1,698.17

Answer:

Hi! I can't really see the graphs on the picture but i can tell you what it should looks like, The graph opens up which means it makes a U shape and The vertex is (- $\frac{9}{4}$ , - $\frac{185}{4}$ ) the Axis of Symmetry is x = - $\frac{9}{4}$ and, if you can find all those points in your graph then you'll get 100% i'm sorry that i can't see the picture but i can see the shape but i also need to see the Units.
