A ball is thrown straight up from the top of a building that is 280 feet high with an initial velocity of 48 ft/s. The height of the object can be modeled by the equation s(t)=−16t2+48t+280.
In two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation. Then, determine the time.
Answer:
i hope it helpful
thank you
Answer:
Answer in interval notation is (3, 5.94].
Step-by-step explanation:
First find the time that the ball is level with the top of the building on its descent. You can do this by solving 280 = -16^2 + 48t + 280 for t. This gives t = 3 seconds .
Then when the ball reaches the ground the time t is obtained by solving 0 = -16t^2 + 48t + 280 This gives t = 5.94
seconds.
Answer in interval notation is (3, 5.94].

Answer:
I think they are all always.
Step-by-step explanation:
They are called rational because they are the ratio, or quotient, of two integers
numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end and does not repeat a pattern.

The number of termites in a colony starts out with 125 insects and increases by 75% each week. Which graph best models the situation?
the first three photos are to this question
Answer:
See attached image.
Step-by-step explanation:
Since the number of termites in a colony starts out with 125 insects and increases by 75% each week we are looking for a graph where the line crosses the y-axis (vertical axis) at 125 and continues to increases by 75%.
From the screenshots given only one graph has a line that intersects at 125 on the y axis and continues upward (see attached image). The other graphs depict a beginning number of termites of 875, 0, and 250.

MARKING BRAINLIEST! A machine pumps 4 1/2 gallons of water every hour. How many gallons of water does it pump after 2 2/3 hours?
Answer:
12 gallons
Step-by-step explanation:
You just multiply both of the numbers.
Answer:
12 Gallons of Water!
___________________________________________________
4.5= 1 hour
9= 2 hours
4.5/3=1.5
So every 1/3 hour equal 1.5 gallons of water!
9+1.5*2= 12
if a bag has 22 orange, 18 red, 12 green and 8 blue marbles what is the probability, that I draw blue marble, keep it, then draw another blue marble?
Answer:
14/885 or 1.58%
Step-by-step explanation:
In total, there are 60 marbles. The probability of drawing a blue marble the first time is 8/60. If you keep the one blue marble that was drawn, the total number of marbles in the bag is 59, and there are now 7 blue marbles. The probability of drawing a blue marble now is 7/59.
In order to find out the total probability of drawing two blue marbles in a row, you need to multiply these two fractions.
(8/60) x (7/59) = 56/3540 = 14/885 (approx. 1.58%)

40+[3{18÷(9-3)-11-9}+4]
Step-by-step explanation:
= 40 + [ 3 { 18 ÷ ( 9 - 3 ) - 11 - 9 } + 4 ]
= 40 + [ 3 { 18 ÷ 6 - 11 - 9 } + 4
= 40 + [ 3 { 3 - 20 } + 4
= 40 + [ 3 {- 17 } + 4
= 40 + ( - 51 ) + 4
= 40 + 4 - 51

A charity organization had to sell a few tickets to their fundraiser just to cover necessary production costs. After selling 101010 tickets, they were still at a net loss of \$800$800dollar sign, 800 (due to the production costs). They sold each ticket for \$70$70dollar sign, 70. Let yyy represent the net profit (in dollars) when they have sold xxx tickets.
Answer:
Price of each ticket = $70
The revenue generated from sales of 10 tickets = 70 x 10 = $700
After selling the 10 tickets, organization was still at loss of $800. This means total product cost of tickets = $800 + $700 = $ 1500
Net Profit = Revenue - Cost
Revenue from n tickets will be = 70n
Cost = $1500
So, net profit as a function of number of tickets sold = P(n) = 70n - 1500

The point G(1,1) is rotated 90° clockwise around the origin. What are the coordinates of the resulting point, G'?
The resulting point's coordinates, G', are rotated 90° clockwise around in the origin are (-1 , -1 ).
What is the coordinate plane's location?A coordinate plane is a two-dimensional plane created by the intersection of the y-axis, a vertical line, and the x-axis, a horizontal line. These really are perpendicular lines that cross at zero, which is known as the origin.
What are a plane's quadrants?Quadrant one (QI) is the upper right fourth of a coordinate plane, where all coordinates are positive. Quadrant two (QII) is the coordinate plane's upper left fourth. Quadrant three (QIII) is the fourth from the bottom left. Quadrant four (QIV) is the fourth from the bottom right.
According to the given data:Point G(1,1)
X= 1 ,Y = 1
We can see that the point lies in the first quadrant because the value of X and Y are the positive.
the coordinates of the resulting point, G' is rotated 90° clockwise around the origin.
As we know that the quadrant plane is divided into 4 part but if the point G rotates at 90 clockwise the the point will shift to the 4 quadrant and in the 4 quadrant the value of X and Y change And it became negative.
So
The resulting point's coordinates, G', are rotated 90° clockwise around in the origin are (-1 , -1 ).

A study concluded that among people with a certain virus, 99.2% of tests conducted were (correctly) positive, while for people without the virus, 97.9% of the tests were (correctly) negative. If 32% of patients actually carry the virus, what's the probability that a patient testing negative is truly free of the virus?
Answer:
Following are the solution to the question:
Step-by-step explanation:
The probability of virus P(V) =0.32
No virus P(NV) =0.66
Patient testing of negative P(TN) = virus, and negative testing+no virus and negative testing
[tex]=0.32(1-0.992)+0.66 \times 0.979 \\\\=0.00256+0.64614\\\\=0.6487[/tex]
This is why the likelihood of a patient being free of the virus is negative.
[tex]= \frac{P(NV) \times\ tested \ negative }{P(TN)}[/tex]
[tex]= \frac{0.66 \times 0.979}{0.6487}\\\\= \frac{0.64614}{0.6487} \\\\=0.996053646[/tex]
Enter a positive common factor (other than 1) of the fractions numerator and denominator 15/25
Which number line represents the solution set for the inequality -1/2x>4
Answer: D
Step-by-step explanation: D because if your turn 1/2 into a decimal point it 0.5 (don't forgot to add the negative) and so i then divided -0.5 from x and just got x then you have to do the same for the other side. So i took 4 and divided it by -0.5 and got -8 to the expression would be x is greater then or equal to -8. you plot the dot at -8 and the line goes in front of it because it is lesser or equal to x (remember you reverse the problem if you say it back words so don't get confused), but after my long explanation just pick D

Step-by-step explanation:
statistical studies are not concerned with understanding the sources of variability in data, only with describing the variability in the data
False.
Variability in statistics is the degree to which data in a set varies, or how much difference there is in a single set of data. The variability definition also refers to the consistency of the pattern in a set of data.
There are many measures of variability to help researchers determine how much variability is contained within a set of data. A simple measure of variability is the range, the difference between the highest and lowest scores in a set.
A concern when using a simple range measure is the existence of outliers, individual scores that are not grouped with the rest of the scores.
Current statistical studies are modern and have a wealth of analysis tools and software to understand the data. Statistics has a wide range of objectives, which aim not only to understand the variability of the data, but also its origin and motivation. For example, if an election poll shows a variation from a previous poll, statisticians will seek to understand the causes of these variability and not just present the variation in the data.
