Answer:
6/12 or 1/2 or 50% or 0.5
Step-by-step explanation:
You have two 6-sided dice, and there are 3 odd numbers on each.
So, you put 6 on top, (the total number of odd outcomes) and 12 on the bottom. (12 total outcomes for both dice.) This simplifies to 1/2 or 50% or .5.
how many nonisomorphic spanning trees does each of these simple graphs have
The characteristics of a nonisomorphic spanning tree are:
One would have 3 vertices of degree 2 and 2 of degree 1, Another spanning tree would have one vertex of degree three, The third spanning tree would have one vertex of degree four.4What is Nonisomorphic?This refers to the quality of a group of things not having the same form and is popularly used in mathematics to show and make identifications of maths objects that are structurally well-defined.

5. ΔPQS ≅ ΔQRT [ASA congruence theorem]
What is the ASA Congruence Theorem?When two pairs of corresponding angles and one pair of included sides of two triangles are congruent, they are congruent triangles based on the ASA congruence theorem.
We are given the following:
QT ≅ PS [a pair of congruent sides]
∠T ≅ ∠S [a pair of congruent angles]
Thus, since QT is parallel to PS, therefore:
∠SPQ ≅ ∠TQR [alternate interior angles theorem]

389m²
74m²
5 m
18 m
6 m
Answer: 379 meters squared
Step-by-step explanation:
Hello!
So, to calculate this area, we need to split it into 3 squares.
You can see that there is a big square, and on top of the big square, there are 2 smaller ones: one to the left and the other to the right.
Area of a square (in this case rectangle) = Lenght multiplied by width
We got 3 squares, if we calculate the area of each one's, we can add them together and get the total area of the irregular shape.
The first square will be the big one:
To get the length of the big square, we need to subtract 5 from 23.
Length of big square = 18 meters
And the width is also 18 meters
Area of the big square = 18 * 18 = 324 meters squared
Now, let's calculate the top left square's area.
That will be 5 meters * 5 meters.
Area of top left square = 25 meters squared.
Top right square's area = 6 meters * 5 meters.
Area of top right square = 30 meters squared
Now, we just gotta add them all up:
324 + 25 + 30 meters squared = 379 meters squared

Z° = 90° - 30° = 60°
Y° = 30°
• Find y.
y/sin(Y) = z/sin(Z)
y/sin(30°) = 4√3/sin(60°)
y/(1/2) = 4√3/(1/2 √3)
y . 1/2 √3 = 4√3 . 1/2

Jocelyn is training for a race by running several miles each day. she tracks her progress by recording her average speed in minutes per mile for each day since she started training. based on the information given, what could jocelyn expect to have for her average speed on the 9th day?
Finding the regression equation, her average speed on the 9th day should be expected to be of 6.92 minutes per mile.
How to find the equation of linear regression using a calculator?To find the equation, we need to insert the points (x,y) in the calculator.
Researching the problem on the internet, the values of x and y are given as follows:
Values of x: 1, 2, 3, 4, 5, 6.Values of y: 8.2, 8.1, 7.5, 7.8, 7.4, 7.5.Hence, using a calculator, the equation for the average minutes per mile after t days is given by:
V(t) = -0.15143t + 8.28
Hence, for the 9th day, t = 9, hence the estimate is:
V(9) = -0.15143(9) + 8.28 = 6.92 minutes per mile.

Find the area of the following region.
The region common to the circles r=-2sin(theta) and r=1
The area of the region common to both circles is -6.67 square units
How to find the area common to both circles?Since r = -2sinθ and r = 1, we find their points of intersection.
So, r = r
-2sinθ = 1
sinθ = -1/2
θ = sin⁻¹(-1/2)
θ = 7π/6
So, the circles intersect at (1, 7π/6)
To find the area of the region common to both circles, we integrate from r = 0 to r = 1 and θ = 0 to θ = 7π/6
[tex]A = \int\limits^1 _0 \int\limits^\frac{7\pi }{6} _0( {r - r}) \, dr \,d\alpha \\A = \int\limits^1 _0 \int\limits^\frac{7\pi }{6} _0( {-2sin\alpha - 1}) \, dr \,d\alpha \\A = -\int\limits^1 _0 \int\limits^\frac{7\pi }{6} _0 {2sin\alpha \, dr \,d\alpha - \int\limits^1 _0 \int\limits^\frac{7\pi }{6} _01} \, dr \,d\alpha \\A = 2[cos\alpha]_{0} ^{\frac{7\pi }{6} } [r]_{0} ^{1} r - [r]_{0} ^{1}} [\alpha ]_{0} ^{\frac{7\pi }{6}}} \\[/tex]
[tex]A = 2[cos{\frac{7\pi }{6} - cos0] [1 - 0] - ([1 - 0][\frac{7\pi }{6} - 0]\\[/tex]
A = 2(-¹/₂ - 1) - (1 × 7π/6)
A = 2(-3/2) - 7π/6
A = -3 - 7π/6
A = (-18 - 7π)/6
A = (-18 - 21.99)/6
A = -39.99/6
A = -6.67 square units

How do you find what exponents of i are? like I know i^2 is -1, but how are you supposed to figure out i^26? do you have to write it all out?
THANK YOU
Answer:
-1
Step-by-step explanation:
so "i" is the square root of -1 (√-1). We know that i² = (√-1)², and that when we square a square root we end back up with whatever is inside of the square root.
This is why i² = -1
We can find a pattern from writing out a few exponents:
i¹ = i
i² = -1
i³ = -i [(-1)(i)]
i⁴ = 1 [-1 · -1]
------
i⁵ = i [(1)(i)]
i⁶ = -1 [(i)(i)]
i⁷ = -i [(-1)(i)]
i⁸ = 1 [(-i)(i)= -(i²)= -(-1) = 1]
------
i⁹ = i [1 · i]
we can see that the pattern of i repeats every 4 numbers, so by dividing 26 by 4 (and finding the remainder), we can figure out which step of the pattern we are on
26 / 4 = 6 [remainder of 2]
we know that there is a remainder of 2, meaning that we are on the "second step" in the pattern: -1
you can do the same thing for any number
hope this helps!!
Answer:
-1
Step-by-step explanation:
4 goes into 26 6 times, and then there's 2 remainder, so it's the same thing as i², which is -1

The center of a circle is at the origin on a coordinate grid. A line with a positive slope intersects the circle at (0, 7). Which statement must be true?
The true statement is the circle has the radius equal to 7.
What is Equation of circle?The general equation for a circle is (x-h)² + (y-k)² = r², where ( h, k ) is the center and r is the radius.
As, standard form of equation of circle is
(x-h)² + (y-k)² = r²
At origin, equation of circle will be
(0-h)² + (0-k)² = r²
r² = x² + y²
Now, The line intersects the circle at (0,7)
r² = 0² + 7²
r² =49
r=7.
