Answer: 20 dallors
Step-by-step explanation:
To obtain an estimate of a parameter of a population, we use confidence intervals.
Confidence intervals:
The larger the sample size, the closest the parameter estimate is to the value of the population, as the margin of error of confidence intervals is inversely proportional to the sample size, that is, a greater sample leads to a smaller margin of error.
Thus, you should select the highest sample size in the options.

Answer:
x > - 5
x < 10
Step-by-step explanation:
Divide 7x>-35 by 7
Divide - 5x>-50 by - 5
Since we divide by a negative whe change the inequality sign.
The standard deviation is the square root of the variance...so that means the variance is the standard deviation squared.
2.3^2 = 5.29 <===
Drawing a diagonal will create two right triangles. So you can use a^2+ b2 =c^2
So approximately 106.47 feet or the square root of 11336
