find the larger angle given the following: the angles are complementary. the smaller angle is equal to 1⁄3 of the larger angle.
The larger angle is 67.5°.
When two angles add up to 90 degrees, they are complimentary.
Let L be the larger angle and S be the smaller angle
Given, smaller angle is 1/3 of larger angle
Thus, S = L/3
But, L + S =90
L + (L/3) =90
4L/3 = 90
4L = 270° .Therefore, L = 270 / 4 = 67.5°.
Thus the larger angle is 67.5°.
Which angle is wider?
Right angles (90 degrees), acute angles (smaller than a right angle), and obtuse angles are the three types of angles that we can recognize (larger than a right angle).
The vertex of an angle is the position where two factors come contact. The Latin word "angulus," which means "corner," is where the term "angle" originates.

in a large population, 71% of the people have been vaccinated. if 5 people are randomly selected, what is the probability that at least one of them has been vaccinated?
The probability that AT LEAST ONE of them has been vaccinated is 0.9979.
Vaccination rate among the population: p = 0.71
Sample size = 5
Assume that X people have received vaccinations.
P(atleast one) = 1 - P (none)
By the binomial distribution, now,
P(none)= (⁵₀) 0.71° (1-0.71)⁵⁻⁰
= 1 × 1 (0.29)⁵
= 0.0021
So,
P(at least one) therefore equals 1 - P (none)
= 1 - 0.0021
= 0.9979
Therefore, the probability that AT LEAST ONE of them has been vaccinated is 0.9979

Matthew scored −33 points in his turn at a video game. In Genevieve's turn, she scored fewer points than Matthew.
Use absolute value to describe Genevieve's score as a loss.
Genevieve lost more than 33 points in her turn at a video game.
Absolute value describes a number's distance from zero on the number line without taking direction into account. A number's absolute value is never negative.
Given that Matthew's score is −33 points.
In Genevieve’s turn, she scored lesser points than Matthew in her turn at a video game.
Let y be the points scored by Genevieve.
Then we have y < -33
⇒ | y | > | -33 | (Using absolute value on both sides)
⇒ | y | > 33
The absolute value of y can be any number greater than or equal to 34, while Genevieve's point in her video game turn is less than or equal to -34.

a. how far is the delivery from the starting point in miles
b. which vehicle would take longer to finish the delivery, the car or the truck
and how much longer would the faster vehicle be than the slower one.
Please explain why
Part A
Answer: 360 milesReason:
The graph shows the highest point occurs when y = 360. After this point, the truck turns around to go back to the starting point (the warehouse perhaps).
In other words, the truck starts at y = 0 when it's at the warehouse. It travels 360 miles to reach the customer, which is represented as the highest point of the V shaped curve. This process takes 6 hours.
Then another 6 hours elapses when the truck drives back to the warehouse. We assume the same route is used, and similar traffic conditions occur for each leg of the trip.
============================================================
Part B
Answer: The truckReason:
The graph shows that the truck takes 12 hours to get back to the warehouse. We look at the x intercept because this is when the distance from the start is back to y = 0 again.
Now we need to find out how long the car takes on its trip.
We'll plug in y = 0 into the car's equation and solve for x.
y = -72|x-5| + 360
0 = -72|x-5| + 360
72|x-5| = 360
|x-5| = 360/72
|x-5| = 5
x-5 = ± 5
x-5 = 5 or x-5 = -5
x = 5+5 or x = -5+5
x = 10 or x = 0
x = 0 or x = 10
This tells us that the car is at the warehouse when x = 0 and when x = 10.
Therefore, the car takes 10 hours to do a round trip, and it's the faster vehicle.

Approximately 33 comma 200 citizens of a country died in automobile accidents in 2015. Express this toll in deaths per day
The toll of death per day in 2015 is 91.
We are given the approximate number of people who died in year 2015, which is 33,200. Now, as per the known fact, the year 2015 has 365 days. So, we can easily calculate the toll in deaths per day by performing division.
Number of deaths in 365 days = 33,200
Number of deaths each day = 33,200 ÷ 365
Performing division to find the number of deaths per day
Number of deaths each day = 90.96
Rounding off the digits to find number of deaths each day
Number of deaths each day = 91
Hence, this toll in deaths per day is 91.

The difference in the x-coordinates of two points is 3, and the difference in the y-coordinates of the two points is 6. What is the slope of the line that passes through the points? 2 3 6 9
Solution :
the differences in the X coordinates and Y coordinates:
The x-coordinate tells you how many steps you have to take to the right (positive) or left (negative) on the x-axis. And the y-coordinate tells you have many steps to move up (positive) or down (negative) on the y-axis.
Given : difference in the x-coordinates of two points is 3
the difference in the y-coordinates of the two points is 6
The slope of the line :
In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.
The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.
Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,
m = change in y/change in x = Δy/Δx
Where “m” is the slope of a line.
Tan θ = Δy/Δx can also represent the slope of the line
So, tan θ to be the slope of a line.
Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The letter ‘ m’ usually represents the slope.
If P(x1,y1) and Q(x2,y2) are the two points on a straight line, then the slope formula is given by:
Slope,
m = Change in y-coordinates/Change in x-coordinates
m = (y2 – y1)/(x2 – x1)
Therefore, based on the above formula, we can easily calculate the slope of a line between two points.
In other terms, the slope of a line between two points is also said to be the rise of the line from one point to another (along the y-axis) over the run (along the x-axis). Therefore,
Slope, m = Rise/Run
Use the slope formula.
the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or
the change in the y values over the change in the x values.
The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2. It does not matter which point you label as the first point and which you label as the second. Don't forget to include the correct sign of each value. Simplify to get the value of the slope. Check the your answer by graphing the points and verifying that the vertical distance between the two points and the horizontal distance between the two points is captured by the numerator and denominator of the slope

D. 15
A box can hold up to 15 items ensuring that every box contains the same quantity of items.
Given there are 10 rulers and 25 packages of tape.
Only one type of item may be present in each box.
Simply put, probability is the likelihood that something will occur.We can discuss the chance or likelihood of various outcomes when we don't know how an event will turn out. Statistics is the study of events that follow a probability distribution.The chance of an event happening is equal to 1 if there is no doubt about its likelihood. In other words, there is a 1 in the chance of an event. An event's probability is zero if there are no chances that it will occur.
In the event when 25 packages of tape and 10 rulers have to be placed in a box, the answer is 25 - 10 = 15.
then only 15 items that can be placed in a box so that each box has the same number of items.
