Answer:
C. -3, 6, -9, -1
Step-by-step explanation:
A coefficient is a number used to multiply a variable.
Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.
Variables with no number have a coefficient of 1.
Example: -x is really -1x.
Answer:
2.897
Step-by-step explanation:
Let us find the mean and variance for the sample first.
105 104 110 112
114 106 108 109
Mean = sum/8 = 108.5
Variance = 12
Std dev = sq rt of variance = 3.464
Std error = std dev/ sq rt n
since n =8, we get std error = 1.225
Since sample size is small, df =8-1 =7
For 95% confidence intervals, t critical value for two tailed=2.365
Margin of error = std error x t critical = 1.225(2.365)
=2.897
<span>A jeweler buys a ring from an artisan for 85$. He sells the ring at his store at 135% increase in price. What is the retail price? PLEASE SHOW UR WORK!!!
