The probability of a chance event is 0.8, it is __________ to happen when compared to a chance event with a probability of 0.9. Select one: equally likely less likely more likely both more and less likely
Answer:
less likely
Step-by-step explanation:
In the question, we are to choose which of the options best fit into blank space.
Talking about probabilities, the probability of events ranges from 0 to 1. With 1 being the highest value the probability of an event can take while 0 is the lowest value the probability of an event can take. The probability of an event can neither be negative, nor greater than 1. It lies between 0 and 1
Now, the closer a probability is to 1, the greater the likelihood of that particular event happening. Events having probabilities closer to 1 are more likely to occur than those farther away from 1 or closer to zero.
In this question, 0.9 is a greater value compared to 0.8. Thus, an event of probability 0.9 is more likely to happen compared with an event with probability of 0.8
In other words, an event with probability 0.8 is less likely to occur compared with an event with a probability value of 0.9

A stone fell from the top of a cliff into the ocean.
In the air, it had an average speed of 16. In the water, it had an average speed of 3 before hitting the seabed. The total distance from the top of the cliff to the seabed is 127 meters, and the stone's entire fall took 12 seconds.
How long did the stone fall in the air and how long did it fall in the water?
Answer:
5 seconds.
Step-by-step explanation:
Make an equation.
Time in air = x
Time in water = 12 - x
16x + 36 - 3x = 127
13x = 91
x = 7
12 - 7 = 5

how can you determine the x value whether it is in the domain of h
Answer:
Well, because this is a khan academy question i guess ill be safe to answer it.
0 is in the domain
4 is in the domain
5 is NOT in the domain.
Step-by-step explanation:
If you plug in 5, you are left with
[tex]\frac{4}{5 - 5}[/tex] = [tex]\frac{4}{0}[/tex] = undefined
However, if you plug in any other value in that list, you are left with a number.
Remember, it isn't in the domain if the number is imaginary (like square root of a negative number) or the answer results in an undefined :)

country.
Which of the following statements best describes the data on the scatter plot?
a) The data on the scatterplot suggests a linear association that could be modeled by the function L(t) - 39.67t +0.37.
b) The data on the scatterplot suggests a linear association that could be modeled by the function L(t) = -0.24t+74.33
c) The data on the scatterplot suggests a linear association that could be modeled by the function L(t) -0.37t +39.67.
d) The data on the scatter plot does not suggest a linear association, so it cannot be modeled by a linear function.
Answer:
L (t) = 0.37t + 39.67

list the intergers that satisfy both these inequalities 2x+9<0 and x>-12
Answer:
-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1
(would really, reallly appreciate the brainliest)
Step-by-step explanation:
2x+9 < 9
can be rewritten as
2x < 0
and therefore
x < 0
the other inequality states that x hat to be bigger then -12
so all integers that satisfy -12 < x < 0 are in the set we search, but be aware that -12 and 0 don't fall into this set, bc -12 for example isn't bigger than -12
Answer:
The integers that satisfy both inequalities are -5, -6, -7, -8, -9, -10 and -11.
Step-by-step explanation:
Firstly, you have to solve the inequality :
[tex]2x + 9 < 0 [/tex]
[tex]2x < - 9[/tex]
[tex]x < - \frac{9}{2} [/tex]
[tex]x < - 4.5[/tex]
Next, given that x is greater than -12 but smaller than -4.5 so the inequality for x is :
[tex] - 12 < x < - 4.5[/tex]
Integer is a positive or a negative number but 'cannot be written in the form of decimal'. So the integers that satisfy both inequalities are :
[tex] - 12 < x < - 4.5[/tex]
[tex]x = - 11, - 10, - 9, - 8, - 7, - 6, - 5[/tex]

A pet store owner, Brooklyn, needs to determine how much food she needs to feed the animals. Brooklyn knows that she needs to order the same amount of bird food as hamster food. She needs four times as much dog food as bird food and needs half the amount of cat food as dog food. If Brooklyn orders 600 packages of animal food, how much dog food does she buy? Let b represent the number of packages of bird food Brooklyn purchased for the pet store.
Answer:
She ordered 85.7 packages as dog food
Step-by-step explanation:
Let b represent bird food, d represent dog food and c represent cat food.
The bird food is 4 times as much dog food. This can be represented as b = 4d
Also, the dog food is half the amount of cat food, it can be represented as d = 1/2c. Therefore, c = 2d
The total feed is 600.
Therefore dog feed + cat feed + bird feed = 600
d + 2d + 4d = 600
7d = 600
d = 600/7 = 85,7
She ordered 85.7 packages as dog food.

Answer:
y = - [tex]\frac{1}{2}[/tex] x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = [tex]\frac{0-2}{4-0}[/tex] = [tex]\frac{-2}{4}[/tex] = - [tex]\frac{1}{2}[/tex]
note the line crosses the y- axis at (0, 2) ⇒ c = 2

Chris achieved these scores in his exams. What was his best result?
a) 34 of 60 for history
b) 29 of 50 for science
c) 39 of 70 for Music
d) 44 of 80 for Math
Answer:
b) 29 of 50 for science
Step-by-step explanation:
We would be finding out his best results by calculating the percentage of his scores in the various exams he took.
a) 34 of 60 for history

39/70 × 100 = 55.7%
d) 44 of 80 for Math
44/80 × 100 = 55%
Looking at the percentage of his scores in various subject in his exams, the subject with the highest percentage is the subject where he had the best result.
That subject with 58% = 29/50 for science.
Therefore, his best results is option b) 29 of 50 for science.

2.20%
.045%
2.25%
4.5%
Answer:
D. 4.5%.
Step-by-step explanation:
Interest earned in 6 months = 572.6 - 560 = $12.60.
As a percentage this is (12.60 * 100) / 560
= $ 2.25%.
So the annual interest is 2 * 2.25
= 4.5%.

A Web music store offers two versions of a popular song. The size of the standard version is 2.8 megabytes (MB). The size of the high-quality version is 4.4 MB. Yesterday, there were 950 downloads of the song, for a total download size of 3284 MB. How many downloads of the standard version were there?
Number of standard version downloads: ?
Answer:
560 downloads of standard version downloads.
Step-by-step explanation:
Let there were number of standard version of downloads = x
and number of high quality version of downloads = y
There were total 950 downloads of the both type of songs.
x + y = 950 -----(1)
Size of the standard version songs = 2.8 MB
and the size of the high quality version songs = 4.4 MB
Total download size = 3284 MB
2.8x + 4.4y = 3284
7x + 11y = 8210 -----(2)
Multiply equation (1) by 11 (-) equation (2)
(11x + 11y) - (7x + 11y) = 10450 - 8210
4x = 2240
x = 560
There were 560 downloads of the standard version downloads.
