Answer: less likely
Step-by-step explanation:
Given
The probability of an event is 0.5
The value of probability always lies between 0 and 1. 0 represents that event will not while 1 represents the certainty of the event.
When 0.5 is compared with 1, it is less likely to happen i.e. chances of this event to occur are less compared to the a event with probability of 1.

Solve the rational inequality x-2/x + x+2/x+3 < 3/2 represent your answer using a number line and using interval notation
Answer and explanation:
To solve the inequality x-2/x + x+2/x+3 < 3/2 we have to first simplify the expressions on the left side of the inequality sign. And so we multiply x by the expressions on the left side to eliminate fractions:
=x(x-2/x)+x(x+2/x)+x(3)< 3/2
=x-2+x+2+3x < 3/2
=5x < 3/2
x < 3/2/5
x < 3/2×5/1
x < 15/2
x < 7 1/2 or 7. 5
easy algebra question below first correct answer gets brainliest
Answer:
x ≈ ± 3.87
Step-by-step explanation:
Given
x² - 3 = 12 ( add 3 to both sides )
x² = 15 ( take the square root of both sides )
x = ± [tex]\sqrt{15}[/tex]
Then x ≈ 3.87 or x ≈ - 3.87 ( to 2 dec. places )

Answer:
59°
Step-by-step explanation:
116-57=59
the outside angle is the 2 inner angles added together
Answer:
59 degrees
Step-by-step explanation:
you can use angle DAB to find out angle BAC by subtracting 180 and 116 to get 64
add 57 and 64 to get 121
subtract 180 and 121 to get 59 degrees.
Jay has an album that holds 500 hockey cards. Each page of the album holds 5 hockey cards. If 17% of the album is empty, how many pages are filled with hockey cards?
Answer: 83
Step-by-step explanation: 17% of 500 is 85. If 17% is empty, that means that you'd take away that 15%. 500 - 85 = 415. If each page holds 5 cards, we need to split those cards up between the pages. 415/5 = 83, so 83 pages will be used.
A bag has 6 red rocks, 1 orange rock, 4 blue rocks, 1 white rock, and 7 yellow rocks. You randomly pull a rock from the bag, keep it out and then pull out another one. What is the probability of not getting a orange and then not getting a orange?
Answer: 17/19
Step-by-step explanation:
Number of red rocks = 6
Number of orange rock = 1
Number of blue rocks = 4
Number of white rock = 1
Number of yellow rocks = 7
Total number of rocks = 19
Probability of not getting a orange the first time will be (1 - 1/19) = 18/19.
Probability of not getting an orange the second time will be: (1 - 1/18) = 17/18
Probability of not getting an orange on both occasion will be:
= 18/19 × 17/18
= 17/19

Answer:
x = 55, because if you look the whole entire bar is 180° in total but you dont have to worry about that because that's not what the question is wanting you to look at, If you look really close there is a half and half on both sides so that means there is a 90° angle so you would have to take 90-35 and that is what gives you your missing angle which is 55.

A normal distribution of 10 and a standard of 1. What is the probability of selecting a number that is at most 9?
Answer:
0.15866
Step-by-step explanation:
The term at most 9 means = less than or equal to 9
This represented as x ≤ 9
We solve using the z score formula
z = (x-μ)/σ, where
x is the raw score = ≤ 9
μ is the population mean = 10
σ is the population standard deviation = 1
z = 9 - 10/1
z = -1
Probability value from Z-Table:
P(x ≤ 9) = 0.15866
Therefore, the probability of selecting a number that is at most 9 is 0.15866

Step-by-step explanation:
can i get brainly
Answer:
- 6, - 21, 12
Step-by-step explanation:
(1)
2x - 7 = - 19 ( add 7 to both sides )
2x = - 12 ( divide both sides by 2 )
x = - 6
(2)
[tex]\frac{x}{-3}[/tex] + 5 = 12 ( subtract 5 from both sides )
[tex]\frac{x}{-3}[/tex] = 7 ( multiply both sides by - 3 to clear the fraction )
x = - 21
(3)
[tex]\frac{3}{4}[/tex] x - 5 = 4 ( add 5 to both sides )
[tex]\frac{3}{4}[/tex] x = 9 ( multiply both sides by 4 to clear the fraction )
3x = 36 ( divide both sides by 3 )
x = 12

If Westville has 15,200 households, predict the number of households that will have exactly 3 computers? Please answer I need help
Answer:
1140 households
Step-by-step explanation:
The results of a computer survey of 80 households in Westville are shown in the table.
So from the table we can see that 6 households have 3 numbers of computers.
So the probability is [tex]$\frac{6}{80}$[/tex]
Therefore, the probability of number of houses from a total of 15,200 houses to have exactly three computers is = [tex]$\frac{6}{80} \times 15200$[/tex]

Mila and samuel had an equal amount of money for shopping. Mila spent $42 and Samuel spent $36. After that, Mila had 1/2 of what Samuel has left. How much money Milla had initially?
Answer:
Mila had $48 initially
Step-by-step explanation:
Let the amount of money they had be x
Mila spent $42; what is left would be x-42
Samuel spent $36: what is left would be x-36
So, what Mila had left is half of what Samuel has; that would be;
x-42 = 1/2(x-36)
2(x-42) = x -36
2x-84 = x -36
2x - x = 84 -36
x = $48
