Answer 1

Answer:

Step-by-step explanation:

[tex]r=\frac{-28}{56}=-\frac{1}{2}\\a_{n}=\frac{-1}{2}a_{n-1}[/tex]

Answer 2

The recursive formula for the sequence is aₙ = (-1/2) * aₙ₋₁

What is a Geometric Series?

A sequence of numbers such that the consecutive term is increasing or decreasing by a fixed ratio is called a geometric series.

The standard equation for geometric series is

Tₙ = a₁ rⁿ⁻¹

The formula above represents the explicit formula to determine the nth term of the sequence.

The recursive formula is used to determine the nth term when (n-1) th term is given.

The geometric sequence is,

56, -28, 14, -7,.................

The first term of the sequence is 56

The common ratio is determined by taking the ratio of the second term to the first term.

r = -28/56 = -1/2

The recursive formula is represented by,

aₙ = r * aₙ₋₁

aₙ = (-1/2) * aₙ₋₁

Brianna is playing darts. So far, she has hit the bullseye 6 times and missed the bullseye 27
times. Considering this data, how many bullseyes would you expect Brianna to get during her
next 88 tosses?

Answers

At 111 tosses (33 + 88) she will hit the bullseye every 3.3 tosses approximately. So she would have hit the bullseye about 33.6 times. You can also rounded up to 34 times.

7/8 + (-3/4) + (-7/-8)+ 3/4

Answers

Answer:

1.75 or  1  3/4

Step-by-step explanation:

7/8 + (-3/4) + (-7/ -8)+ 3/4

Simplify

7/8 -3/4 -7/-8 +3/4

We can get rid of -3/4 + 3/4, because together they = 0.

7/8 - 7/-8

So then we divide and subtract and get

1). Use the same ratio as 16 people in 25 square feet to estimate the size of a
crowd that is 10 feet deep on both sides of the street standing along a 1-mile
section of a parade route.

Answers

Answer:

33,792 people

Step-by-step explanation:

The parade route is rectangular in nature. The area of the parade route will be expressed as:

Area = Length × Breadth

If the route is 10feet deep, the length of the route = 10feet

Is the section of the route is 1 mile, the width of the parade route = 1mile × 5280ft = 5280ft

Area of the parade route = 10×5280 = 52,800ft²

If 16 people in 25 square feet is used to estimate the size of a crowd, the number of a crowd in a 52800ft² parade route is expressed as;

25ft² = 16

52800ft² = x

Cross multiply

25×x = 16×52800

25x = 844,800

x = 844,800/25

x = 33,792

Hence there are 33,792 people on 1-mile section of a parade route that is 10ft deep.
