Answer:
4/3
Explanation:
For xy-plane coordinates, points are written as (x, y).
This question gives us two points and two line equations to solve this. Let's start with the first one.
Since p is the x value of the point and r is the y value of the point, we can place these values in our equation y = x + b as follows:
r = p + b
Now we do the same with our second point and line equation. We will substitute 2p for x and 5r for y in the equation y = 2x + b. So we get this:
5r = 2(2p) + b
5r = 4p + b
Since we have this two equations with the same two variables, now we can solve them using the elimination method.
In this case I eliminated b as it is constant in both equations. To do this I subtract the equations in order to cancel the b variable.
5r = 4p + b
r = p + b
_______ -
5r - r = 4p + b - p - b
4r = 3p
4/3 = p/r
What the sample suggests is that; the mean body temperature couldvery possibly bevery possibly be 98.6 °F.
<h3>What is the Confidence Interval?</h3>
For a 99% Confidence Interval and DF = 103 - 1 = 102, the value of z = 2.33.
The formula for confidence interval is;
CI = x⁻ ± z(σ/√n))
We are given;
Sample mean; x⁻ = 98.9
standard deviation; σ = 0.67
sample size; n = 103
Thus the confidence Interval is;
CI = [98.9 - 2.33(0.67/√103)], [98.9 + 2.33(0.67/√103)]
CI = (98.9 - 0.154, 98.5 + 0.154)
CI = (98.36, 98.64)
Thus, 98.6 is contained within the 99% CI,and so we can conclude that the the mean body temperature could very possibly bevery possibly be 98.6 °F.
