Using a t-distribution calculator, it is found that the critical value of the test statistic t is 
.
<h3>How to find the critical value of a t-test?</h3>
- The critical value is found using a calculator.
The inputs are:
- The amount of degrees of freedom, which is one less than the sample size.
In this problem, we have a<u> lower(left-tailed) test, with 10 - 1 = 9 df and a level of significance of 0.1</u>, hence the critical value is .

Answer:
its c or d
Step-by-step explanation:
Adding 14.52 and -14.52 cancels it out
The answer is 6.89

Answer:
The linear equation that represents each function is y=mx+b. While The m represent the slop so instead of writing you write the slope provided. Then multiply by the X + b which is your Y-intercept.
Here is an example,
The slope is 2/3 and the y intercept is 6, write a linear equation for this sequence.
y= (2/3). X +6

Answer: the total rent expense be for the entire 7-year lease is $713476
Step-by-step explanation:
The rate at which the rent increases each year is in geometric progression. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as
Sn = (ar^n - 1)/(r - 1)
Where
n represents the number of term(years) in the sequence.
a represents the first term in the sequence.
r represents the common ratio.
From the information given,
a = $85000
r = 1 + 6/100 = 1.06
n = 7
Therefore, the sum of the first 7 terms(7 year lease), S7 is
S7 = (85000 × 1.06^(7) - 1)/1.06 - 1
S7 = (85000 × 1.06^(7) - 1)/0.06
S7 = 42808.57/0.06
S7 = $713476
