1st let's calculate r the common ratio:
r = (-20)/4 = (100/-20) = -5
Value of nth term = a₁.rⁿ⁻¹, where a₁= 1st term and n, the rank
Value of nth term = 4r⁽⁷⁻¹⁾ = 4.(-5)⁶
Value of nth term = 62,500
Answer:
21.4m
Step-by-step explanation:
Circumference : x diameter
is approximately 3.142
3.142 x 6.8 = 21.3656
Nearest tenth = 21.4m
Given:
year 0 - 2005 : 90,000
year 1 - 2006 : 91,200
91,200 - 90,000 = 1,200
1,200 / 90,000 = 0.013
90,000 (1+0.013)^1 ⇒ 90,000 (1.013)^1 = 91,170 OR 91,200
The best representation of the relationship between x and f(x) is choice 2.
f(x) = 90(1.013)x
Answer:
We need a sample size of at least 383.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
85% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 85% confidence level with an error of at most 0.03
We need a sample size of at least n.
n is found with 
Then
Rounding up
We need a sample size of at least 383.
One of two form of joint ownership is one form of holding property. There are two forms of joint ownership, which are the joint tenants and tenants by entirely. The joint tenants form is one form of holding property which commonly used by married couples for minimizing their estate taxes, where they share the property ownership.
