Answer:
<h3>Option A) Estimates a likely interval for a population mean is correct</h3><h3>Hence a confidence interval for a population mean is used to <u>
Estimates a likely interval for a population mean</u></h3>
Step-by-step explanation:
Given that a confidence interval for a population mean <u>Estimates a likely interval for a population mean</u>
For :
A confidence interval is a range of values that’s likely to include a population value with a certain degree of confidence.
It can be expressed as a the (percentage value)
where by a population mean lies between an upper and lower interval.
Therefore a confidence interval for a population mean is used to <u>Estimates a likely interval for a population mean</u>
Option A) Estimates a likely interval for a population mean is correct
<h3>Hence a confidence interval for a population mean is used to <u>
Estimates a likely interval for a population mean</u></h3>
Answer: <em><u>4.</u></em> This is because 1 and 1/5 = 1.2 and 3/10 = 0.3 and 1.2 divided by 0.3 = 4. That's because 1.2 can be split into 4 equal groups and each group has 0.3.
Find the length of the line from A to C, which would be the radius using the distance formula:
Distance = √(-5 +1)^2 + 1+2)^2)
Distance = √(4^2 + 3^2)
Distance = √25
Distance = 5
The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^2, where h and k is the center point X and y values and r is the radius.
The center of the circle is located at A ( -1,-2) and the radius is 5.
Replace h, k and r with those values:
(x - (-1))^2 + (y- (-2))^2 = 5^2
Simplify to get:
(x+1)^2 + (y+2)^2 = 25
Answer:
61
Step-by-step explanation:
Let's write out what we know:
Noon temp: 54
Over the day, the temperature:
increased 8, decreased 3, increased 14, decreased 2, and decreased 10.
54+8-3+14-2-10 = 61
