Answer: option C. Emily got 12 text messages, adn 5 were from Jasmine. The probability a text message is from Jasmine is 5/12.
Explanation:
All the other options are theoretical probabilities because they were determined using the equation:
probablity = number of positive events / total number of possible events.
While, experimental probabilities are determined from actual results of an experiment (test). That is what the option C. describes. It compares the number of times that she actually got a message (5) with the number of trials (12). It is not determined theoretically.
The answers A and D can be true for some people but are not true generally: they depend on the people's natural organization skills.
Answer B is wrong: one needs to also consider their income, spending, savings, etc...
the correct answer is the following one: <span>C. frequently discovers the complexity of his or her financial situation. </span>
Answer:
D. y = 2x² + 1
E. y = x²
Step-by-step explanation:
Linear function:
A linear function has the following format:
In which a is the slope and b is the y-intercept. A constant function is linear, as it is the special case in which a = 0.
In this question:
In options D and E, the highest exponent of x is 2, which means that they are not linear functions, and so these options are the answer.
Count the number of cubes in the first layer.
There is 16 cubes in the first layer.
Now divide the total number of cubes by the cubes per layer:
48 cubes / 16 cubes per layer = 3 layers.
Answer:
A = 50°
B = 60°
C = 70°
Step-by-step explanation:
If we draw a line from each vertex through the center of the circle, we perpendicularly bisect the line joining the adjacent tangent points.
We then know the original angle is halved and the remaining angle of each right triangle is complementary to half the original.
Now we can subtract the known angles along each line of the original side to find the remaining angle
