Answer:
B
Step-by-step explanation:
Hotter = Temperature goes up
Colder = Temperature goes down
Since it's getting cooler outside, temperature drops
20°C - 22°C= -2°C
Answer:89%
Step-by-step explanation: its the probability that they will get anything other than an arm tattoo. So you subtract 43 from 389 and it gives you 346,
346/389 x 100% = 88.9%
9514 1404 393
Answer:
x = -6
Step-by-step explanation:
A plot of the points tells you one is above the other on the same vertical line. The equation for a vertical line is ...
x = constant
In order for the line to go through points that have x-coordinates of -6, the constant must be -6. The equation of the line is ...
x = -6
Answer:
C. Slope and
Step-by-step explanation:
We're missing the graph itself, but I can make an educated guess:
- Assuming x = volume and y = mass:
density = mass/volume
x = volume = run
y = mass = rise
mass/volume = rise/run = slope
The slope of the line (assuming the graph is purely linear) represents mass/volume, which is the formula for density.
I had to Google the density of silver itself. Do the math from the graph for a more appropriate answer, as the graph may be less scientifically precise.
Answer:
The frequency does not change with more trials
Step-by-step explanation:
To predict: the probability of the coin landing heads up
Solution:
Probability refers to the chances that an event will occur in an experiment. The value of probability lies between 0 and 1. 0 indicates impossible event and 1 indicates a sure event. The probability of an event can not be greater than 1.
When a coin is tossed, there are two possible outcomes: heads (H), tails (T).
In case of the probability of the coin landing heads up, the frequency does not change with more trials.
