Answer:
- temperature is decreasing as time passes
- x-axis
- hot drink temperature (°C)
Step-by-step explanation:
1. Each value of temperature is lower than the one previous, so we can say the temperature is decreasing. We also notice that the rate of decrease is getting smaller, possibly because the temperature is approaching a horizontal asymptote.
__
2. The horizontal axis, where temperature is plotted, is conventionally called the x-axis.
__
3. The label on the vertical axis is "temperature" and the graph title is "cooling a hot drink ...", so we presume the dependent variable is the temperature of a hot drink.
The probability of rolling a 6 on the 1st roll is
, since there is only 1 out of 6 sides of the dice that has six pips.
The probability of rolling an odd number is
, since there are 3 out of 6 sides of the dice that has an odd number of pips.
Then the probablity of both events happening one after another is
. You have to multiply both probabilities of the events:
The answer is B.
The mean is the average so, in this case, the average age of the voters. To get the average the person must take 100 random people who voted, as taking any others will not give them the average age.
42.5° supplement equals 137.5°, you do 180-42.5=137.5, supplementary angles add up to 180°
