Answer:

1/4

Step-by-step explanation:

There are 12 possible outcomes

The ones that have a head and an even number are H2 H4 H6

P( head and even number) = head and even number/ total outcomes

= 3/ 12

=1/4

Using compound interest and a graphing calculator, it is found that it will take about 15 years for the loan to be paid off.

<h3>What is compound interest?</h3>

The amount of money earned, in compound interest, after t years, is given by:

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

In which:

A(t) is the amount of money after t years.

P is the principal(the initial sum of money).

r is the interest rate(as a decimal value).

n is the number of times that interest is compounded per year.

For this problem, the parameters are given as follows:

A(0) = 95000, r = 0.06, n = 12.

Hence the value of the loan after t years is:

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

$A(t) = 95000\left(1 + \frac{0.06}{12}\right)^{12t}$

$A(t) = 95000(1.005)^{12t}$

You have monthly payments of $1,200, hence the amount paid after t years is:

P(t) = 12 x 1,200t = 14400t

Then we have to solve for:

A(t) = P(t)

$14400t = 95000(1.005)^{12t}$

Which is solved in the graph below, meaning that it will take about 15 years for the loan to be paid off.

5. Se hizo una encuesta a estudiantes, de una carrera de un total de 6000 estudiantes encuestados el 75% le gusta leer. ¿Cuántos

Nataly_w [17]

La encuesta indica que de entre todos los estudiantes de una carrera, 4500 les gusta leer.

<h3 /><h3>Percentage</h3>

The percentage is the given definition for a fraction whose denominator is equal to 100. It is represented by %. See the example: $\frac{30}{100} =\frac{3}{10}=0.3*100=30 \%$ .

The question gives:

6000 students
75% of students like to read

Then, you will have:

$6000\cdot \frac{75}{100}\\ \\ 6000\cdot \frac{3}{4}\\ \\ \frac{18000}{4} =4500$

La edad de 4 miembros de una familia suman 70. Mamá es 6 veces más grande que su hijo y 10 veces más grande que su hija. Papá es

3241004551 [841]

Answer:

3 5 30 32

Step-by-step explanation:

The question in English is

The age of 4 members of a family adds up to 70. Mom is 6 times bigger than her son and 10 times bigger than her daughter. Dad is 2 years older than Mom. How old are each of the family members? Write the result in ascending order and separated by spaces

Let

x----> Mon's age

y----> Son's age

z----> Daughter's age

w---> Dad's age

we know that

x+y+z+w=70 -----> equation A

x=6y ----> y=x/6 -----> equation B

x=10z ----> z=x/10 -----> equation C

w=2+x -----> equation D

substitute equation B, C and D in equation A and solve for x

x+(x/6)+(x/10)+(2+x)=70

Multiply by 60 both sides

60x+10x+6x+120+60x=4,200

136x=4,200-120

x=4,080/136

x=30 years

Find the value of y

y=x/6 -----> y=30/6=5 years

Find the value of z

z=x/10 ----> z=30/10=3 years

Find the value of w

w=2+x ----> w=2+30=32 years

Write the result in ascending order and separated by spaces
