27.36/75*100 = 36.48A red die and a blue die are thrown. What is the probability that the numbers on the two dice are different?.
Answer:
5/6
Step-by-step explanation:
The probability of both dice to roll the same number would be 5/6
The probability that the numbers on the two dice are different is 5/6.
Given that, a red die and a blue die are thrown.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
There are six different possible outcomes for a dice, the set (S) of all the outcomes can be listed as follows:
(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
Total number of outcomes = 36
Number of favorable outcomes = 30
Now, probability = 30/36
= 5/6
Therefore, the probability that the numbers on the two dice are different is 5/6.

If Triangle PQR ~ Triangle VST with a scale factor of 2:5, find the value of x.
Answer:
x = 11.2 unitsStep-by-step explanation:
QR is the corresponding side to ST since ΔPQR ~ ΔVST, considering the order of vertices.
Since the scale factor is 2/5, the ratio of corresponding sides is:
QR/TS = 2/5x/28 = 2/5x = 28*2/5x = 56/5x = 11.2Find the roots of the quadratic equation:
[tex]2x^{2} - x - 10 = 0[/tex]
2x^2 - x = 10
=> 2x^2 - x - 10 = 0
=> 2x^2 - (5 - 4)x - 10 = 0
=> 2x^2 - 5x + 4x - 10 = 0
=> x(2x - 5) + 2(2x - 5) = 0
=> (2x - 5)(x + 2) = 0
Either, Or,
2x - 5 = 0 x + 2 = 0
=> 2x = 5 => x = - 2
=> x = 5/2
Answer:
[tex]x1 = \frac{5}{2} \: \: and \: x2 = - 2[/tex]
Step-by-step explanation:
So, our equation is:
2x² - x - 10 = 0
The numbers before x are a, b, and c
We must first find the discriminant which is equal to b² - 4*a*c
D = b² - 4 * a * c
Be careful here, b is -1 because we have minus before x and c is -10
D = (-1)² - 4*2*-10
D = 1 + 80
D = 81
Now we need to find the roots of the equation, since D is greater than 0, the roots are equal to (-b ± sqrt(D)) / 2*a
[tex]x1 = \frac{ -( - 1) + \sqrt{81} }{2 \times 2} = \frac{1 + 9}{4} = \frac{10}{4} = \frac{5}{2} [/tex]
and for x2 we will put minus:
[tex]x2 = \frac{ - ( - 1) - \sqrt{81} }{2 \times 2} = \frac{1 - 9}{4} = \frac{ - 8}{4} = -2 [/tex]

what kind of quadrilateral is PQRS? EXPLAIN YOUR REASONING.
1.) What is the length of side PS? = 9
2.) What is the length of side SR? = 9
3.) What is the length of side PQ? = 29
4.) What is the length of side QR? = 29
since i already found the lengths for these angles, what kind of quadrilateral is PQRS?
Answer:
PS = 3SR = 3PQ = √29QR = √29kiteStep-by-step explanation:
A quadrilateral with perpendicular diagonals, one of which is a line of symmetry, is a kite.
Perhaps a more conventional definition of a kite is that it is a quadrilateral with two pairs of congruent adjacent sides.
1, 2)The lengths PS and SR can be found by counting grid squares along the line segments. Each has a length of 3. They constitute one pair of congruent adjacent sides.
PS = SR = 3
__
3, 4)The lengths of PQ an QR can be found using the distance formula. Essentially, it uses the Pythagorean theorem to compute the hypotenuse of a right triangle whose legs are the differences in x- and y-coordinates. For PQ and QR, those differences are 2 and 5, so the lengths of those segments are √(2² +5²) = √29.
PQ = QR = √29
__
5)The figure has two pairs of congruent adjacent sides, so is a kite.
So i figured out the first but I don't know the rest please help?

If the two consecutive numbers is 23 , find them
Step-by-step explanation:
Let the two consecutive natural numbers be x and x+1
Now, according to the problem
x+(x+1)=23
⇒ 2x+1=23
⇒ 2x=23−1
⇒ 2x=22
⇒ x=22÷2=11
The one number is 11
The next number is x+1=11+1=12
Hence the numbers are 11 and 12.

O x=5+2 5
Ox=5+ 35
O x= 10+2.5
X= 10+ 35
Answer:
x = 5 + 35
Step-by-step explanation:
This is correct if you mean x2 as in x^2
The value of x in the equation x² - 10x+ 25 = 35 is x=5±√35
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given equation is x² - 10x+ 25 = 35
Now we to solve for x by changing the equation to quadratic equation.
Subtract 35 from both sides
x² - 10x+ 25 - 35 = 0
x² - 10x -10 =0
By complete square method.
(x-5)² -10 -5² = 0
(x-5)²=10+5²
(x-5)²=10+25
(x-5)²=35
Take square root on both sides
(x-5)=±√35
x=5±√35
Hence, the value of x in the equation x² - 10x+ 25 = 35 is x=5±√35

Express the terms of the following sequence by glving an explicit formula
2, -2, -6, -10, –14,...
Answer:
[tex]a_{n}[/tex] = - 4n + 6
Step-by-step explanation:
There is a common difference between consecutive terms of the sequence
- 2 - 2 = - 6 - (- 2) = - 10 - (- 6) = - 14 - (- 10) = - 4
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 2 and d = - 4 , then
[tex]a_{n}[/tex] = 2 - 4(n - 1) = 2 - 4n + 4 = - 4n + 6
