Answer: уравнение имеет 2 решения:
x₁ = - 4; x₂ = - 2.
Step-by-step explanation:
Ix + 3I = 1
1) x + 3 = 1
x + 3 - 3 = 1 - 3
x = -2
2) - (x + 3) = 1
x + 3 = - 1
x + 3 - 3 = - 1 - 3
x = - 4
fair die was rolled 10 times with the following results: 5 5 1 3 2 1 5 6 5 1 Which of the following is a correct statement about the next 10 rolls of the same die? There will be three 1’s because there were three 1’s in the first 10 rolls. There were zero 4’s in the first 10 rolls; therefore, there will be zero 4’s in the next 10 rolls. The probability of getting a 5 is greater than the probability of anything else. Each value (1 to 6) has exactly the same probability of being rolled.
Answer:
Each value (1 to 6) has exactly the same probability of being rolled.
Step-by-step explanation:
Given
Rolls: 10
Outcome: 5 5 1 3 2 1 5 6 5 1
Required
Which is true about the next 10 rolls
In the roll of a fair die (as stated in the question), each face has equal probability of being the outcome of individual rolls.
This implies that options (a), (b) and (c) are not true because they do not support the above statement,
Hence, (d) is correct

Answer:
7/2 = 35/10 & 3/5 = 6/10
Step-by-step explanation:
This is very hard to be explained, sorry.
Answer:
The first one: 35/10
Second: 6/10
Step-by-step explanation:
These are the answers because since you are trying to solve to get a denominator of 10, you must multiply both the to and bottom numbers by whatever you need to get the denominator to 10. For example, for 3/5 you would multiply both the top and bottom numbers by 2, because you nned to multiply the denominator by 2 to get 10.

Choose 5 cards from a full deck of 52 cards with 13values (2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A) and 4 kinds(spade, diamond, heart, and club). Count how many possible ways to geta(a)Two-pairs: Two pairs plus another card of a different value, for example:(b)Flush: five cards of the same suitbutdifferent values, for example: (c)Full house: A three of a kind and a pair, for example: (d)Four of a kind: Four cards of the same value, for example:
Answer:
a) 182 possible ways.
b) 5148 possible ways.
c) 1378 possible ways.
d) 2899 possible ways.
Step-by-step explanation:
The order in which the cards are chosen is not important, which means that we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question, we have that:
There are 52 total cards, of which:
13 are spades.
13 are diamonds.
13 are hearts.
13 are clubs.
(a)Two-pairs: Two pairs plus another card of a different value, for example:
2 pairs of 2 from sets os 13.
1 other card, from a set of 26(whichever two cards were not chosen above). So
[tex]T = 2C_{13,2} + C_{26,1} = 2*\frac{13!}{2!11!} + \frac{26!}{1!25!} = 182[/tex]
So 182 possible ways.
(b)Flush: five cards of the same suit but different values, for example:
4 combinations of 5 from a set of 13(can be all spades, all diamonds, and hearts or all clubs). So
[tex]T = 4*C_{13,5} = 4*\frac{13!}{5!8!} = 5148[/tex]
So 5148 possible ways.
(c)Full house: A three of a kind and a pair, for example:
4 combinations of 3 from a set of 13(three of a kind ,c an be all possible kinds).
3 combinations of 2 from a set of 13(the pair, cant be the kind chosen for the trio, so 3 combinations). So
[tex]T = 4*C_{13,3} + 3*C_{13.2} = 4*\frac{13!}{3!10!} + 3*\frac{13!}{2!11!} = 1378[/tex]
So 1378 possible ways.
(d)Four of a kind: Four cards of the same value, for example:
4 combinations of 4 from a set of 13(four of a kind, can be all spades, all diamonds, and hearts or all clubs).
1 from the remaining 39(do not involve the kind chosen above). So
[tex]T = 4*C_{13,4} + C_{39,1} = 4*\frac{13!}{4!9!} + \frac{39!}{1!38!} = 2899[/tex]
So 2899 possible ways.

Ana, Profesora de Psicología de una escuela, planeo realizar un estudio sobre las
respuestas de los espectadores a ciertos aspectos de las peliculas A By Después
de encuestar su clase de 55 estudiantes, determinó la siguiente información: 17
han visto A. 17 han visto B. 23 han visto c. 6 han visto A y B. & han visto A y C 10
han visto By C 2 han visto las tres peliculas.
a. ¿Quántos estudiantes han visto exactamente dos de estas peliculas?
b. ¿Cuántos estudiantes han visto exactamente una de estas peliculas?
C. ¿Cuántos estudiantes no han visto estas películas?
d. ¿Cuántos estudiantes han visto A. pero ninguna de las otras?
Answer:
The answer is below
Step-by-step explanation:
El número de personas que vieron solo A = n (A) = 17
El número de personas que vieron solo B = n (B) = 17
El número de personas que vieron solo C = n (C) = 23
El número de personas que vieron A y B = n (A ∩ B) = 6
El número de personas que vieron A y C = n (A ∩ C) = 8
El número de personas que vieron B y C = n (B ∩ C) = 10
El número de personas que vieron las tres películas = n (A ∩ B ∩ C) = 2
1) Número de estudiantes que han visto dos películas = n (A ∩ B) + n (A ∩ C) + n (B ∩ C) = 6 + 8 + 10 = 24
2)
n (A∩ B '∩ C') = n (A) -n (A ∩ B) -n (A ∩ C) -n (A ∩ B ∩ C) = 17-8-6-2 = 1
n (A'∩ B ∩ C ') = n (B) -n (A ∩ B) -n (B ∩ C) -n (A ∩ B ∩ C) = 17-6-10-2 = 1
n (A'∩ B '∩ C) = norte (C) -n (UNA ∩ C) -n (B ∩ C) -n (UNA ∩ B ∩ C) = 23-8-10-2 = 3
estudiantes que no han visto = 55 - n (A∩ B '∩ C') -n (A'∩ B ∩ C ') - n (A'∩ B ∩ C') - n (A ∩ B) -n ( B ∩ C) -n (UNA ∩ C) -n (A∩ B ∩ C) = 55-1-1-3-6-8-10-2 = 24
3)
número de alumnos que no han visto =
4)
número de estudiantes que vieron solo A = n (A∩ B '∩ C') = 1

Step-by-step explanation:
Noah has dd dimes and qq quarters. He has no less than 17 coins altogether. Write this situation as an inequality.
Answer:
(dd + qq) ≥ 17
Step-by-step explanation:
We know that the number of coins that we have should be greater than or equal to 17, because it can be no less than 17. So we add dd and qq together, and we say that that sum must be greater than or equal to 17.
A rectangle and 2 congruent quarter circles were used to make the figure shown. Which measurement is closest to the area of the figure in square centimeters?
Answer:
109.3
Step-by-step explanation:
The area of the figure in square centimeters is 89.6 cm².
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
Given:
We have the figure consist of rectangle and 2 quadrants.
Then to calculate area of figure
= Area of 2 quadrant + area of rectangle
So, Area of 2 quadrant = 2 x πr²/4 = πr²/2
= 3.14 x 5² /2
= 19.625 cm²
and, area of rectangle= l x w= 7 x 10 = 70 cm²
Thus, area of figure
= Area of 2 quadrant + area of rectangle
= 19.625 + 70
= 89.625 cm²

Answer:
132
Step-by-step explanation:
a straight line is 180% , so if the other triangle has a 48% we would subtract 180% by 48%.
Answer:
132
Step-by-step explanation:
Since those two angles are linear, they would form to make 180 degrees. So 180-48 is 132.

2/6 blue socks 2/6 green socks and the rest are white socks what would the answer be
Answer:
I think ita would be 2/6 as well
Step-by-step explanation:
simplify it down to 1/3 and the blue take up one third and so does the green socks
Answer:
2/6 socks are white.
Step-by-step explanation:
The denominator (6) is the amount of socks you have.
If 2/6 are blue and 2/6 are green. 4/6 are Blue & Green.
To find the remaining amount of socks you would simply subtract 6/6 by 4/6
That would leave you with 2/6 of the socks being WHITE.
