Step-by-step explanation:
Answer:
-0.329
Step-by-step explanation:
The formula for Geometric ratio is
an = ar^n - 1
Where
a = First term = 18
r = Common ratio = ?
n = Number of term= 6
Hence
a6 = 18 × r^6-1
From the question
a6 = -2/29
Hence:
-2/29 = 18 × r^6-1
-2/29 = 18 × r⁵
Divide both sides by 18
-2/29 ÷ 18 = 18 × r⁵/18
-2/29 × 1/18 = r⁵
r⁵ = -1/261
Take the fifth root of both sides
⁵√(r⁵) = ⁵√(-1/261)
r = -0.3286032834
Approximately = -0.329
Therefore, Common ratio = -0.329

Answer :
<h3>The average of a distribution is equal to the summation of x divided by the number of observations is called <u>Mean</u></h3>
Step-by-step explanation:
<h3>The average of a distribution is equal to the summation of x divided by the number of observations is called <u>Mean</u></h3><h3>For :</h3>
- We know that
where N is the number of observations
<h3>Therefore the average of a distribution is known as Mean.</h3>
Original shape will contract when scale factor is less than 1 , expand when scale factor is greater than 1 and it doesn't change when scale factor is 1
A scale factor is a number that can be used to change the size of any geometrical figure or shape in relation to its original size. It is the ratio of the sizes of the original and dilated figures.
It is denoted by "k"
The magnitude of the scale factor is taken into account, and it cannot be zero. The scale factor has the ability to either increase or decrease the size of an object.
The basic formula for calculating the scale factor of a dilated figure is as follows:
Scale = dimension of preimage / dimension of image
According to the question,
(a) If scale factor is less than 1 , k < 1 then the original shape will contract means It's size will decrease
(b) If scale factor is greater than 1 , then image will enlarge and it would expand
(c) If scale factor is equal to 1 , then No change in shape nor in size
