O Yes; AB has an endpoint and continues in one direction forever.
O Yes; AB is one-dimensional.
O No; AB continues forever in both directions.
O No; AB has two endpoints.
Answer:
O No; AB has two endpoints.Step-by-step explanation:
Ray - a continuous line therefore, do not have two endpoints.[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]
AB is not a ray. It has two endpoints.
What is ray?"It is a part of a line that has a fixed starting point but no end point."
For given example,
We have been given a part of a line AB.
The starting point is A and the end point is B.
We know, one of the end of the ray is denoted by arrow.
Since both the ends of given figure are fixed, it is not ray.
AB is called as line segment.
Therefore, AB is not a ray. It has two endpoints.

if 5 is a root of the quadratic equation x²+4x-45=0 find the other root of the equation
Answer:
-9
Step-by-step explanation:
x² + 4x - 45
x² + (9x - 5x) - 45
x² + 9x - 5x - 45
x(x + 9) - 5(x + 9)
(x + 9)(x - 5)
x + 9 = 0
x = -9
Answer: -9
Step-by-step explanation:
If 5 is a root of the quadric equation, then
x²+4x-45=0
x²-5x+9x-45=0
x(x-5)+9(x-5)=0
(x-5)(x+9)=0
The other root is -9

The sum of a number and it's absolute value is negative.
Answer:
False; the scenario is not possible.
Step-by-step explanation:
This scenario is not possible. I will demonstrate it by representing a number by [tex]x[/tex]. There are two possibilities: [tex]x[/tex] and [tex]-x[/tex]. Let's try both:
[tex]x + |x|[/tex]
[tex]x + x[/tex]
[tex]2x[/tex]
The sum for positive [tex]x[/tex] and its absolute value is not negative. Let's try with the negative value of [tex]x[/tex] now:
[tex]-x +|-x|[/tex]
[tex]-x + x[/tex]
[tex]0[/tex]
The sum for negative [tex]x[/tex] and its absolute value is not negative either, it is zero which is neither negative or positive. Therefor, we can safely say that the scenario described is not possible.

A bag has 6 watermelon, 5 grape and 1 green apple jolly rancher. . What is the probability of picking a
watermelon, put it back then green apple?
Answer:
1/24
Step-by-step explanation:
We want to find the probability of picking a watermelon AND picking a green apple right after. These events are completely independent of each other as the watermelon is put back, and picking a watermelon/green apple does not affect the chances of getting the other the next/previous time. The formula for this is P(A) * P(B), with P(A) being the probability of event A happening and P(B) being the probability of event B happening. It does not matter which event is which.
Let's say picking a watermelon is event A and picking a green apple is event B. There are 6 watermelons and 6+5+1 = 12 jolly ranchers, so there is a 6/12 = 1/2 chance of picking a watermelon. There is 1 green apple and still 12 jolly ranchers, so there is a 1/12 chance of picking a green apple jolly rancher.
Multiplying these two, we get (1/2) * (1/12) = 1/24
HELP ILL GIVE BRAINLIEST QUICK!!
Answer:
Dan is correct
Step-by-step explanation:
First, I calculated the amount of hours that the graph shows in total, coming up with a total of 3,085 hours. I do this by multiplying the number of adults surveyed by the number of hours they spent. So for the first column, (80+70)*1, second column, (90+80)*2, third column, (135+130)*3, fourth column, (140+135)*4, and fifth column, (65+75)*5 if you get what I mean. Then I add up all values. Knowing that there were two sets of 500 American adults interviewed already, I came to the conclusion that 1,000 total adults were surveyed. Finally, I divided the total number of hours(3,085) by the total number of adults interviewed (1,000) to get a mean of 3.085 hours, rounding it to 3 hours and proving that Dan is correct.

Step-by-step explanation:
Convert 1.05 to a fraction
Answer:
21/20
Step-by-step explanation:
One way to look at it:
Convert 1.05 to a percentage so it's easier to see it as fraction out of 100
fraction x 100 = %
1.05 x 100 = 105%
105% means 105/100, and reducing the fraction gives 21/20.
21/20 = 1.05

(Last one is point W)PLEASEEE HELP DUE SOON
Part 1
Answers: point Q, point R, point S
-----------------
Explanation:
All three points mentioned are on the same straight line; hence they are collinear.
=======================================================
Part 2
Answer: Point T or point W
Pick one of those answers only
-----------------
Explanation:
Notice how point W is not on the line shared by points Q, R, and S. The same can be said about point T with that line.
So we would say that the set {T, Q,R,S} is not a collinear set of points. We could also say {W, Q,R,S} is also not collinear.
Mike won 59 super bouncy balls playing
hoops at his school's game night. Later,
he gave four to each of his friends. He
only has 7 remaining. How many friends
does he have?
Answer:
13 friends
59-7=52(to find the number of balls that Mike gave to his friends if he gave them only one ball each)
52/4 =13(if 52 is the number of balls that he gave them if he gave them one each, if he gives them four balls each all you have to do is to divide it by 4)
Nicole had the exact amount of money to buy 9 pens.
Instead she bought only 5 pens.
She used the rest of the money to buy 7 notebooks at $1.20 each.
How much money did Nicole have at first?
Answer:
18.90$
Step-by-step explanation:
Pen = p
Notes = n
n = 1.20
5p + 7n = 9p
-9p + 5p + 7n = 0
-4p + 7n = 0
-4p + (7*1.2) = 0
-4p + 8.4 = 0
8.4/4 = p
2.1 = p
9p = 9*2.1
9p = 18.90$

Which of the following is equal to 1/2 or -1/2? Check all that apply.
Sin (7π/6)
Sin (4π/3)
Cos (5π/3)
Cos (π/6)
Cos (5π/6)
Sin (5π/6)
Answer:
Cos (5π/3)
Cos (π/6)I think this one
Answer:
Below in bold.
Step-by-step explanation:
The sine is positive in the first and second quadrants and negative in other 2.
The cosine is positive in the first and 4th quadrants and negative in other 2.
Note that sin(pi/6) = 1/2 and cos(pi/3 = 1/2).
sin(7pi/6) = 1/2
cos(5pi/3) = 1/2
sin(5pi/6) = 1/2
