Answer:
(a) unique triangle(b) more than one triangle(c) no triangle possibleStep-by-step explanation:
1. Three sides lengths uniquely specify a triangle.
__
2. Three angle measures specify the shape of a triangle, but not its size. More than one triangle is possible with any given set of angle measures.
__
3. If the lengths do not satisfy 3 + 7 > 10, which they do not, then no triangle can be formed.

Describe these points with a double inequality
Answer:
-2<x[tex]\leq[/tex]11
Step-by-step explanation:
The line spans from -2 to 11 so we know that those are the values that will be in our expression. -2 has an open circle, therefore, we do not include that value. So any value greater than -2 but not equal to -2 is included. -11 has a closed circle that ends the line segment. This means that any value less than 11 or greater than 11 is included. Therefore the expression would be x is greater than -2 and less than or equal to 11.
Points on the number will be defined by the inequality → -2 < x ≤ 11.
Symbols to describe an inequality on a number line: A hollow circle describes the value where the hollow circle is
located will not be included and the inequality will be denoted by
(< or >).
Solid circle describes the value to be included and denoted by(≤ or ≥).
Dark line between two numbers denotes the values of 'x'between the numbers,
From the number line given in the picture,
Dark line starts with a hollow circle from x = -2
Dark line ends with a dark circle at x = 11.
Inequality for this situation will be → -2 < x ≤ 11
Therefore, points on the number will be defined by the inequality → -2 < x ≤ 11.

Someone help me with this question!!
9514 1404 393
Answer:
∠Y = 45°
Step-by-step explanation:
The sum of complementary angles is 90°.
∠Y + ∠S = 90°
∠Y + (3(∠y) -90°) = 90°
4∠Y = 180° . . . . . . . . . . . . add 90°, collect terms

Traffic on Rosedale Road in Princeton, NJ, follows a Poisson process with rate6cars per minute. Adeer runs out of the woods and tries to cross the road. It takes the deer a random time (independentof everything else), uniformly distributed between2and5seconds, to cross the road. If there is acar passing while the deer is on the road, it will hit the deer with portability2/3(independent ofeverything else). Find the probability of a collision.
Answer:
Step-by-step explanation:
From the given information:
6 cars pass on the road per minute. This implies that per minute, we will have:
6/60 passes = 0.1 car passing the road per second
Thus, for 5 sec; we have:
5 × 0.1 = 0.5
Let assume X signifies to be a random variable which denote the no of cars in the next 5 minutes and which follows a Poisson distribution.
i.e.
[tex]X \sim Poisson (0.5)[/tex]
[tex]\text{P(collision occurs) = 1 - P(no car coming in the following 5 seconds)} \\ \\ =1 - P(X=0)[/tex]
[tex]= 1- \dfrac{[e^{-0.5\times 0.5^0}]}{0!}[/tex]
[tex]= 1 - e^{-0.5}[/tex]
[tex]= 1 - 0.6065[/tex]
[tex]= 0.3935[/tex]
However, the possibility of collision supposes the deer requires 2 seconds to cross the road can be computed as follows:
Suppose Y denote the arbitrary variable that addresses the no. of cars passing the road in 2 secs, then;
[tex]Y \sim Poisson (0.2)[/tex]
[tex]\text{P(collision occurs) = 1 - P(no car coming in the following 2 seconds)} \\ \\ =1 - P(Y=0)[/tex]
[tex]= 1- \dfrac{[e^{-0.2\times 0.2^0}]}{0!}[/tex]
[tex]= 1 - e^{-0.2}[/tex]
[tex]= 1 - 0.8187[/tex]
[tex]= 0.1813[/tex]

60 / 12 = 5
Answer:
15
Step-by-step explanation:
9.30am-10.30am is 1h
1h=60min
60min/12min= 5
he has done 5 pots until his break,
after his break,
10.30am +20min = 10.50am
10.50am-12.50pm is 2h
2h=120min
120min/12min=10
10+5=15
He has done 15 pots

To find:
The correct application of the quadratic formula.
Solution:
If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
We have,
[tex]y=6x^2-9x+22[/tex]
Putting [tex]y=0[/tex], we get
[tex]6x^2-9x+22=0[/tex]
Here, [tex]a=6,b=-9,c=22[/tex]. Using the quadratic formula, we get
[tex]x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(6)(22)}}{2(6)}[/tex]
The correct application of the quadratic formula is [tex]x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(6)(22)}}{2(6)}[/tex].

find the measure of each given angle
9514 1404 393
Answer:
∠2 = 19°
Step-by-step explanation:
Angles that are equal to 161° are vertical and corresponding angles: 1, 4, 5.
Angles that are equal to the supplement of 161° are the remaining angles: 2, 3, 6, 7.
Angle 2 is the supplement of 161°:
∠2 = 180° -161°
∠2 = 19°
