C. None of the above

Step-by-step explanation:

we know that

The number of students who signed up for different after school activities are

Cooking------------> 9 students

Chess---------------> 4 students

Photography-----> 8 students

Robotics-----------> 11 students

Total of students -----> (9+4+8+11)=32

<u><em>Verify each statement</em></u>

case A) The ratio of photography students to all is 4:1

The statement is false

Because the ratio of photography students to all is 8:32

Simplify

1:4

case B) For every 1 chess student there are a total of 16 students

The statement is false

Complete the recursive formula of the geometric sequence -0.3, 0.9, -2.7, 8.1. ....
SSSSS [86.1K]

Answer:

(-1)ⁿ(3)ⁿ/10

Step-by-step explanation:

The first term a = 0.3, the second term, ar = 0.9. The common ratio r = ar/a = 0.9/-0.3 = -3.

From the general term of a geometric series,

U = arⁿ⁻¹

= (0.3)(-3)ⁿ⁻¹

= (3/10)(-3)ⁿ⁻¹

= (-1)ⁿ⁻¹(3)(3)ⁿ⁻¹/10

= (-1)ⁿ(3)ⁿ/10

Nutka1998 [239]
Assume x are Erica's classes & y are Bo's classes.

x=2y-13
Replacing the value of x into the first equation
2y-13+y=35
3y=35+13
y=16 classes
x=2*16-13=19 classes

write and solve this equation: Samantha is one year less than twice her brother Jack’s age. If the sum of their ages is 41, how
Rufina [12.5K]

Answer:

Samantha's age = 27 years

Step-by-step explanation:

  • Let Jack's age be = x

As Samantha is one year less than twice her brother Jack’s age.

  • So Samantha's age = 2x-1

As the sum of their ages is 41.

Thus, the equation become

x+2x-1 = 41

3x-1 = 41

3x = 42

Dividing both sides by 3

x = 14

It indicates that Jack's age = 14 years

Therefore,

Samantha's age = 2x-1 = 2(14)-1 = 27 years
