What is the slope of a line that contains the points (8-,4) and (10,-2)

erastova [34]

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{-2 - (-4)}{10 - 8} = \frac{-2 + 4}{2} = \frac{2}{2} = 1$

   y - y₁ = m(x - x₁)
y - (-4) = 1(x - 8)
   y + 4 = 1(x) - 1(8)
   y + 4 = x - 8
       - 4    - 4
   y = x - 12

The lengths, in inches, of adult corn snakes are normally distributed with a population standard deviation of 6 inches and an un

liubo4ka [24]

Answer: 2.460

Step-by-step explanation:

The formula of Margin of Error for (n<30):-

$ME=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

Given : Sample size : n= 18

Level of confidence = 0.90

Significance level : $\alpha=1-0.90=0.1$

Using the t-distribution table ,

Critical value : $t_{n-1, \alpha/2}=t_{17,0.05}= 1.7396$

Standard deviation: $\sigma=\text{ 6 inches }$

Then, we have

$ME=( 1.7396)\dfrac{6}{\sqrt{18}}\approx2.460$

Hence, the margin of error (ME) of the confidence interval with a 90% confidence level = 2.460

What is the present value of an investment that will pay you $97,000 in four years. assume the appropriate discount rate is 7.75

frutty [35]

Total = Principal * (1 + (rate/n))^n*years
where "n" is the number of compounding periods per year (in this case it is 365)
Total = 97,000 * (1.0002123288)^365*4
Total = 97,000 * (1.0002123288)^1,460
 =132,247.89
