The probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60 is 157/456.
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
Given is table showing the results of a survey on the number of text messages per month for people of different ages.
we need to find the probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60,
P(E) = favorable outcomes / total outcomes
Favorable outcomes = 157
Total outcomes = 456
Hence the required probability = 157 / 456
Hence the probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60 is 157/456.

One train is traveling 120 m with a velocity of 52 km/h and a
second train is traveling in the opposite direction with a
velocity of 20 km/h. How long will it take for them to
completely pass one another?
Answers
Answer: It took the train 11 s to completely pass the other.
11 seconds it takes for them to completely pass one another if one train is travelling 120 m with a velocity of 52 km/h.
What is distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
One train is travelling 120 m with a velocity of 52 km/h.
A second train is travelling in the opposite direction with a velocity of 20 km/h.
Here, the length of the second train is not given:
We are assuming the length is 100 m
Relative velocity = 52+20 = 72 km/h = 20 meter/seconds
Total distance: = 120 + 100 = 220 m
The time = 220/20 = 11 seconds
Thus, 11 seconds it takes for them to completely pass one another if one train is travelling 120 m with a velocity of 52 km/h.

Answers
Answer:
A
Step-by-step explanation:
Answer:
A. 72
Step-by-step explanation:
There are two ways to solve this problem. First of all, this quadrilateral is a trapezoid because the top two angles are congruent and there is one pair of parallel lines. One way to solve the problem is to remember all trapezoids have a measure of 360. So, mD=360-(108+108+72); this equals 72. Additionally, in a trapezoid, the bottom two angles are always congruent; therefore, angle D must equal 72 degrees.

The probability that a randomly selected student is a girl is 0.52, and the probability that a student is a girl and in an art class is 0.20. Giver that a student is a girl, what is the probability she is in an art class?
0.20
0.32
0.38
0.52
Answers
Answer: The answer is 0.38
Step-by-step explanation:
Well, everything is given, as stated in the question "the probability that a student is a girl and in an art class is 0.20."
It's given that the probability that a student is a girl is 0.52.
However, in the question, it said that it's given a student is a girl.
You have the probability that a student is a girl and in art class, so you need to find what 0.52 was multiplied by which would be the probability of someone being in art class. Knowing this you can do 0.20 / 0.52 to get 0.38.

From conditions 1, 4 the triangles can be formed and from conditions 2,3 the no triangles can be formed.
What is a triangle?A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.
For the given situation,
The table shows the set of measures, we need to determine which condition can make triangles.
Condition 1:
AB = 15 cm, BC = 20 cm, ∠B = 40°
By SAS criteria, this condition can form a triangle.
Condition 2:
AB = 20 cm, BC = 15 cm, ∠C = 40°
Here the condition is Side-Side-Angle. There is no such criteria, so no triangle can be formed.
Condition 3:
BC = 10 cm, BC = 5 cm, ∠A = 20°
Here side length of BC alone is given. With one side and one angle, no triangle can be formed.
Condition 4:
AC = 5 cm, BC = 10 cm, AB = 14 cm
Here three sides are given, so we can form a triangle.
Hence we can conclude that from conditions 1, 4 the triangles can be formed and from conditions 2,3 the no triangles can be formed.

Answers
Answer:
0.0337 = 3.37% probability that a particular death is due to an automobile accident
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
What is the probability that a particular death is due to an automobile accident?
Total of 1008 deaths.
34 resulted from an automobile accident. So
[tex]p = \frac{34}{1008} = 0.0337[/tex]

y = [?]x +
Answers
Answer:
y(x) = 3x + 5
Step-by-step explanation:
Since the rosemary grows by the same number of centimeters each year, this situation is modeled by a linear function.
Height starts at 5 meters and grows 3 centimeters per year.
This means that the height after a certain number of years, represented by x, is given by:
y(x) = 3x + 5
