Answer:
slope is 2
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
Well I would think the answer would be about 220
Answer:
The temperature difference in 5 minutes will be 12.38ºC
Step-by-step explanation:
The difference in temperature after t minutes is given by the following equation:
In which T(0) is the initial temperature and r is the decrease rate, as a decimal.
Decreases by 5% every minute.
This means that
What will the temperature difference be in 5 minutes if it is currently 16°C
This is T(5) when
So
The temperature difference in 5 minutes will be 12.38ºC
The confidence interval is
.
This means that if we take repeated samples, 99% of the intervals would contain the population proportion.
To construct this interval, we use
,
where
Since 590/1016 said they had a cat and a dog, p=0.581 and N=1016:
We need the z-score associated with this confidence level:
Convert 99% to a decimal: 99/100 = 0.99
Subtract from 1: 1-0.95 = 0.01
Divide by 2: 0.01/2 = 0.005
Subtract from 1: 1-0.005 = 0.995
Using a z-table, we see that this value is equally distant from z=2.57 and z=2.58, so we will use z=2.575:
Answer:<em> </em><em>p=</em><em>-</em><em>4</em>
<em> </em><em> </em><em>Since,</em><em> </em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>></em><em> </em><em>p-4=</em><em>-</em><em>8</em>
