Answer:A
Step-by-step explanation:
0=-2x^2+x+3
-2x^2+x+3=0
a=-2 b=1 c=3
Answer:
true
Step-by-step explanation:
because the variable terms are in the left side of the equation and everything else in right side.
Answer:
For a sample size of 10, the t-value is about 3.25 (from tables) at a 99% confidence interval.
Explanation:
When the standard deviation for the population is not known, the confidence interval estimate for the population mean is performed with the Student's t-distribution.
The confidence interval for the mean is calculated as

where

= sample mean,
s = sample standard deviation,
t = t-value (provided in tables),
n = sample size.
When reading the t-value, (n-1) is called the df or degrees of freedom.
Y – y1 = m(x – x1)
y-(-1)=-5(x-2)
Y+1=-5(x-2)
Answer:
non of these choices I guess
