1. If tn =3n - 2, the value of S5 is:
(a) 35
(b) 40
(c) 45
(d) 30
If tn = 2n? + 3n, the value of Sais:
(a) 90
(b) 70
(C) 80
(d) None of these
Answer:
1) if tₙ = 3*n - 2, we want to find the value of S(5), which is the sum of the first 5 terms.
We can simply compute the sum directly, it is:
S(5) = t₁ + t₂ + t₃ + t₄ + t₅
S(5) = (3*1 - 2) + (3*2 - 2) + (3*3 - 2) + (3*4 - 2) + (3*5 - 2)
S(5) = 35
Then the correct option here is a).
2) This is not correctly written.
I will assume that we the n-th term is:
tₙ = n^2 + 3*n
And we want S(5) again
Then:
S(5) = t₁ + t₂ + t₃ + t₄ + t₅
S(5) = (1^2 + 3*1) + (2^2 + 3*2) + (3^2 + 3*3) + (4^2 + 3*4) + (5^2 + 3*5)
S(5) = 100
So the correct option is (d)
(Notice that if we had chosen any other S(n), the answer is still option (d) )

Answer:
Step-by-step explanation:
The average rate of change in the value of the account for the first 3 years
is $1.58.
What is an exponential function?When the independent variable is in the power of some function we call them an exponential function, For example, [tex]e^x[/tex] is an exponential function.
Given, The value of the account, in dollars, can be modeled as
[tex]V(t) = 30(1.05)^t[/tex].
Now at t = 3 or after 3 years, it is [tex]V(t) = 30(1.05)^3[/tex].
V(3) = $34.73 and he initially deposited $30.
So, The average rate of change is $(34.73 - 30)/3 = $(4.73)/3 = $1.58.

Panthers' distribution is symmetric.
O B. Both distributions are symmetric.
C. Both distributions are negatively skewed.
D. The Wolverines' distribution is positively skewed, but the Panthers'
distribution is symmetric.
Answer: Its A
Step-by-step explanation:
have a great day!
The Wolverines' distribution is negatively skewed, but the Panthers' distribution is symmetric , Option A is the correct answer.
What is a Box Plot ?Box plot is a systematic way of distribution of data in a five number summary , minimum, first quartile , median, third quartile , and maximum .
The box plot is said positive skewed when the mean of the plot is greater than the median and the mean is more towards the lower quartile.
The box plot is said positive skewed when the mean of the plot is less than the median and median is towards the upper quartile.
In the box plot given it can be seen that the Panther's have a symmetrical box plot while , The Wolverines' distribution is negatively skewed .
Therefore , Option A is the correct answer.

Find the HIGHEST Common
and lowest common multple
of 36 and 48 using
prime factors
Answer:
Step-by-step explanation:
Least common multiple can be found by multiplying the highest exponent prime factors of 36 and 48. First we will calculate the prime factors of 36 and 48.
Prime Factorization of 36
Prime factors of 36 are 2, 3. Prime factorization of 36 in exponential form is:
36 = 22 × 32
Prime Factorization of 48
Prime factors of 48 are 2, 3. Prime factorization of 48 in exponential form is:
48 = 24 × 31
Now multiplying the highest exponent prime factors to calculate the LCM of 36 and 48.
LCM(36,48) = 24 × 32
LCM(36,48) = 144

1. Los estudiantes de primer grado de la IE Miguel Grau son 184, si la relación entre los que usan anteojos y los que no usan es de 3/5. ¿Cuántos estudiantes usan anteojos?
Answer:
69 estudiantes.
Step-by-step explanation:
Sabemos que el número total de estudiantes en primer grado es 184.
También sabemos que la relación entre los que usan anteojos y los que no es 3/5.
Esta relación es igual al cociente entre el número de estudiantes que usan anteojos y el número de estudiantes que no usan anteojos.
Si definimos las variables:
A = número de estudiantes que usa anteojos
B = número de estudiantes que no usa anteojos.
Tenemos la relación:
A/B = 3/5
podemos reescribir como:
A = (3/5)*B
Y también sabemos que el número total de estudiantes es 184, entonces tendríamos que:
A + B = 184.
Podemos aislar B en esta segunda ecuación para luego reemplazarlo en la primera.
Aislando B obtenemos:
B = 184 - A
Si reemplazamos esto en la otra ecuación obtenemos:
A = (3/5)*B
A = (3/5)*(184 - A)
Ahora podemos resolver esto para A.
A = (3/5)*184 - (3/5)*A
A + (3/5)*A = (3/5)*184
A*(1 + 3/5) = (3/5)*184
A*(5/5 + 3/5) = (3/5)*184
A*(8/5) = (3/5)*184
A = (5/8)*(3/5)*184
A = 69
Podemos concluir que 69 estudiantes usan anteojos.

Mr.Chamberlain is planning a field trip for his math classes to visit a museum.It costs $300 to rent the bus, then $7.50 per student for entry to the museum Mr. Chamberlain only has a budget of $1,000 from the school. Which equality below represents the number of students he can bring on the trip?
Answer:
Equation - $1000=$300+$7.50x
Answer - Mr. Chamberlain can included 93 Student Entries
Step-by-step explanation:
$1000 (budget)
$300 (cost to rent bus)
$7.50 (cost of each student entry)
$1000-$300= $700
Now we have found out that Mr. Chamberlain has $700 left to spend on student entries.
$700/$7.50 = 93.333
Round 93.333 down to 93 because you can't have 1/3 of a student (obviously)
93 = the max number of student entries that Mr. Chamberlain can have for the museum field trip
