The solution to show the absolute value inequality is (-3,-2)
<h3>What is absolute inequality?</h3>An absolute value inequality is an expression with absolute functions as well as inequality signs
Interval = -3 to 2
The intervals are represented with open parenthesis, which shows that -3 and 2 are excluded values of the inequality.
So, we have:
-3 < x < 2
As an interval notation,
(-3,-2)
Hence, the solution to the absolute value inequality is (-3,-2)

Answer:
Confidence interval: (0.04649,0.04913)
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 100,000
Number of people who donated, x = 4781
95% Confidence interval:
Putting the values, we get:
is the required 95% confidence interval for the true proportion of their entire mailing list who may donate.
Here we know that Margie is standing on a bridge looking at the river. She throws a rock over the bridge with an initial velocity of 60 ft/sec. The height, h, of the rock at the rime t seconds after it was thrown can be modeled by the equation:
To calculate how long will it take for the rock to reach the surface of the water, we need to set . So:
Given that time can't be negative, we just choose the positive value. Therefore, <em>it will take 4.70 seconds for the rock to reach the surface water.</em>
