Read the passage from the Houston Chronicle about air quality in Houston in 2019. “I’m surprised and disturbed that Houston’s air quality worsened in this year’s [American Lung Association ‘State of the Air’] report,” said Luke Metzger, director of Environment Texas. “The trend since 1999 had been one of steady progress and instead now it seems we are backtracking and that’s bad news particularly for the hundreds of thousands of people who have asthma or other vulnerable populations like senior citizens. . . .” Current models estimate that more than 60 percent of ozone pollution is from cars, according to Raun, and to address that, the city is trying to encourage practices such as the use of mass transit and transitioning to fuel-efficient or low-emission vehicles. Which statement best describes air quality in Houston since 1999? Air pollution has been steadily increasing in Houston since 1999. Air pollution has been steadily decreasing in Houston since 1999. Air pollution has varied depending on climate conditions since 1999. Air pollution has steadily decreased since 1999, before suddenly increasin
Answer:
D.) Air pollution has steadily decreased since 1999, before suddenly increasing.
Step-by-step explanation:
right on edge
Air pollution has steadily decreased since 1999, before suddenly increasing. Therefore, option D is the correct answer.
What is low-emission?A car with low emissions produces very little pollution. A low-emission zone is an area where polluting cars are either not allowed or must pay to enter. They've developed a new kind of low-emission buses.
Vehicles that are either designated as Zero emission Vehicles or as Low Emission Vehicles are considered low-emitting and fuel efficient.
Air pollution has steadily decreased since 1999, before suddenly increasing is the statement best describes air quality in Houston since 1999. As the use of mass transit and transitioning to fuel-efficient or low-emission vehicles.

Answer:C
Step-by-step explanation:I took the test got a
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?
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.

An engineer traveled 150 mi by car and then an additional 630 mi by plane. The rate of the plane was three times the rate of the car. The total trip took 8 h. Find the rate of the car.
Answer:
Step-by-step explanation:
150 mile by car x mph
630 mile by plane 3x mph
Total travel time equal 8 hours
150 / x mile / (mile / hour) = hour
630 / 3x mile / (mile / hour) = hour
150/x + 630/3x = 8 hours
450/3x + 630/3x = 8 hours
450 + 630 = 8(3x) = 24x
1080 = 24x
45 = x the rate of the car is 45 mph

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.

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

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
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.
