Need Help What is l9l
Answer:
the absolute value of l9l is 9
Step-by-step explanation:
because if you look on a number line when you are calculating the absolute value it is how many numbers away from zero so it is always positive.
Answer: +9
Step-by-step explanation: When an integer is written with vertical bars on either side, it means that we take the absolute value of that integer.
The absolute value of an integer is its
distance from zero on a number line.
|9| is +9 because it's 9 units from zero on the number line.

£ represents a group of 30 people that visited paris for a weekend break. 13 of the group visited the eiffel tower (ET) 16 of the group visited the no tre-dame cathedral (NDC) 7 of the group did not visit either of these places a person is chosen at random from the group. what is the probability that this person only visited one of the two places?
Answer:
Step-by-step explanation:
The probability that a person chosen at random from a group of 30 people only visited one of the two landmarks, the Eiffel Tower or the Notre-Dame Cathedral in Paris, is 17/30.
To calculate the probability that a person in a group of 30 people who visited Paris only visited one of the two landmarks - the Eiffel Tower (ET) or the Notre-Dame Cathedral (NDC), we need to apply the principles of set theory and probability.
Firstly, we know that:
13 visited the ET
16 visited the NDC
7 did not visit either place
Adding the numbers of visitors to both places gives us a total of 29 (13 ET + 16 NDC). However, the total number of people is 30, and 7 did not visit either, which implies that 23 people (30 - 7) visited at least one site. Therefore, 29 - 23 gives us 6 people who have visited both places.
To find the number who visited only one place, we subtract those who visited both from the total who visited each:
For ET only: 13 (visited ET) - 6 (visited both) = 7
For NDC only: 16 (visited NDC) - 6 (visited both) = 10
Adding these gives us 17 (7 ET only + 10 NDC only) who visited just one site. Hence, the probability that a person chosen at random visited only one of the two places is:
P(visited only one site) = Number who visited only one site / Total number of people
P(visited only one site) = 17 / 30
Therefore, the probability is 17/30.

suppose 7,330 dollars is invested at 14.8% per annum for 10 years compounded monthly, how many dollars will be earned in interest during those 10 years, to the nearest cent
Answer:
$24,580.12
Step-by-step explanation:
Lets use the compound interest formula to solve:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
P = initial balance
r = interest rate (decimal)
n = number of times compounded annually
t = time
First, change 14.8% into a decimal:
14.8% -> [tex]\frac{14.8}{100}[/tex] -> 0.148
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:
[tex]A=7,330(1+\frac{0.148}{12})^{12(10)}[/tex]
[tex]A=31,910.12[/tex]
Now subtract that number from our original amount invested:
[tex]31,910.12-7,330=24,580.12[/tex]
The dollars earned in interest is $24,580.12
Bob's Burgers surveyed a random sample of 70 Sunset Park Food Festival
attendees about their favorite type of burger. Of the attendees surveyed,
32 said that bacon cheeseburgers were their favorite type of burgers.
There are 1400 Sunset Park Food Festival attendees. Based on the data,
what is the most reasonable estimate for the number of Sunset Park Food
Festival attendees whose favorite type of burger is a sausage bacon
cheeseburger? *
Answer:
The most reasonable estimate for the number of Sunset Park Food Festival attendees whose favorite type of burger is a sausage bacon cheeseburger is 760.
Step-by-step explanation:
Assume that Bob's Burgers provides two types of burgers:
Bacon cheeseburgers (B)Sausage bacon cheeseburger (S)Of the random sample of N = 70 attendees, the number of people who said that bacon cheeseburgers were their favorite type of burgers is 32.
Then the number of people who said that sausage bacon cheeseburgers were their favorite type of burgers is, n (S) = 70 - 32 = 38.
Compute the probability that a randomly selected attendee like sausage bacon cheeseburger as follows:
[tex]P(S) = \frac{n(S)}{N}=\farc{38}{70}=0.543[/tex]
It is provided that there are 1400 Sunset Park Food Festival attendees.
Let the random variable X be defined as the number of attendee who likes sausage bacon cheeseburgers.
Then the random variable X will follows a Binomial distribution with parameter n = 1400 and p = 0.543.
This is because, there are a fixed number of trial in the experiment, each trial has the same number of outcomes, i.e. a person either likes bacon cheeseburgers or sausage bacon cheeseburgers and each trial has the same probability of success, i.e. P (S).
The expected value of a Binomial random variable is:
[tex]E(X)=n\times p[/tex]
Compute the expected number of attendees whose favorite type of burger is a sausage bacon cheeseburger as follows:
[tex]E(X)=n\times p[/tex]
[tex]=1400\times 0.543\\=760.2\\\approx 760[/tex]
Thus, the most reasonable estimate for the number of Sunset Park Food Festival attendees whose favorite type of burger is a sausage bacon cheeseburger is 760.

Simplify. Rewrite the expression in the form 5n.
5(2) x 5(5) =
To simplify the expression 5(2) x 5(5), we first calculate the result as 250. To rewrite this in the form 5n, we find a number n such that 5 times n equals 250, which is 50. Thus, the original expression can be written as 5(50).
Explanation:The question asks to simplify the given mathematical expression. The expression is 5(2) x 5(5). When we multiply the numbers in each parenthesis with 5, it simplifies to 10 x 25, which equals 250 when multiplied together. This answer, however, is not in the form of 5n.
To rewrite the answer in form of 5n, we need to find a number that, multiplied by 5, equals to our answer, 250. This number is 50, because 5 times 50 equals 250.
Therefore, the expression 5(2) x 5(5) equals 250 and can be rewritten in the form of 5n as 5(50).

Find how many six-digit numbers can be formed from the digits 2, 3, 4, 5, 6 and 7 (with repetitions), if:
the numbers formed must be divisible by 25
or
the odd digits must occupy even positions (i.e. 2nd, 4th, and 6th) and the even digits must occupy odd positions (i.e. 1st, 3rd and 5th)
Answer:
case 1 = 2592
case 2 = 729
case 1 + case 2 = 2916
(this is not a direct adition, because case 1 and case 2 have some shared elements)
Step-by-step explanation:
Case 1)
6 digits numbers that can be divided by 25.
For the first four positions, we can use any of the 6 given numbers.
For the last two positions, we have that the only numbers that can be divided by 25 are numbers that end in 25, 50, 75 or 100.
The only two that we can create with the numbers given are 25 and 75.
So for the fifth position we have 2 options, 2 or 7,
and for the last position we have only one option, 5.
Then the total number of combinations is:
C = 6*6*6*6*2*1 = 2592
case 2)
The even numbers are 2,4 and 6
the odd numbers are 3, 5 and 7.
For the even positions we can only use odd numbers, we have 3 even positions and 3 odd numbers, so the combinations are:
3*3*3
For the odd positions we can only use even numbers, we have 3 even numbers, so the number of combinations is:
3*3*3
we can put those two togheter and get that the total number of combinations is:
C = 3*3*3*3*3*3 = 3^6 = 729
If we want to calculate the combinations togheter, we need to discard the cases where we use 2 in the fourth position and 5 in the sixt position (because those numbers are already counted in case 1) so we have 2 numbers for the fifth position and 2 numbers for the sixt position
Then the number of combinations is
C = 3*3*3*3*2*2 = 324
Case 1 + case 2 = 324 + 2592 = 2916

The values of [tex]\( \sin \theta \)[/tex] are [tex]\( \frac{\sqrt{35}}{6} \)[/tex] and [tex]\( -\frac{\sqrt{35}}{6} \)[/tex], and the value of [tex]\( \tan \theta \)[/tex] is [tex]\( \sqrt{35} \)[/tex].
Given that [tex]\( \cos \theta = \frac{1}{6} \)[/tex], we need to find [tex]\( \sin \theta \)[/tex] and [tex]\( \tan \theta \)[/tex].
First, we can find [tex]\( \sin \theta \)[/tex] using the Pythagorean identity:
[tex]\[\sin^2 \theta + \cos^2 \theta = 1\][/tex]
Substitute [tex]\( \cos \theta = \frac{1}{6} \)[/tex]:
[tex]\[\sin^2 \theta + \left(\frac{1}{6}\right)^2 = 1\][/tex]
[tex]\[\sin^2 \theta + \frac{1}{36} = 1\][/tex]
[tex]\[\sin^2 \theta = 1 - \frac{1}{36} = \frac{36}{36} - \frac{1}{36} = \frac{35}{36}\][/tex]
[tex]\[\sin \theta = \pm \sqrt{\frac{35}{36}} = \pm \frac{\sqrt{35}}{6}\][/tex]
So, [tex]\( \sin \theta \)[/tex] could be [tex]\( \frac{\sqrt{35}}{6} \)[/tex] or [tex]\( -\frac{\sqrt{35}}{6} \)[/tex].
Next, to find [tex]\( \tan \theta \)[/tex], we use the definition:
[tex]\[\tan \theta = \frac{\sin \theta}{\cos \theta}\][/tex]
Substitute [tex]\( \sin \theta = \pm \frac{\sqrt{35}}{6} \) and \( \cos \theta = \frac{1}{6} \)[/tex]:
[tex]\[\tan \theta = \frac{\frac{\sqrt{35}}{6}}{\frac{1}{6}} = \sqrt{35}\][/tex]

Answer:

Step-by-step explanation:
Angles are named with the vertex listed in the middle of the three letters. For example, ∠AFB is formed by rays FA and FB. Point F is the vertex of the angle, where the rays meet.
Adjacent angles share a ray. Generally the shared ray will be the only ray between the other two rays identifying the angles. For example, ∠AFB and ∠BFC (or ∠CFB) are considered to be adjacent because shared ray FB is between rays FA and FC.
Given the names of two angles, you can look to see if any of the rays are shared.
Looking at the next answer choice, ∠AFB and ∠CFD we see that the rays involved in the first angle are FA and FB; in the second angle they are FC and FD. There are no common rays here, so these angles are not adjacent.
∠BFC and ∠CFD share ray FC. They are adjacent.
∠BFC and ∠DFE have no shared rays.
∠CFD and ∠DFE share ray FD. They are adjacent.

Which of the following shows the correct order of the numbers?
..0.8
The correct answer is: A. -1.3, -1.2, 0.8, 0.9. Hence the correct option is a.
Start by comparing the negative numbers:
Since -1.3 is a smaller number than -1.2, we know -1.3 comes first.
Compare the negative numbers with the positive numbers:
All negative numbers are less than any positive number. Therefore, both -1.3 and -1.2 come before 0.8 and 0.9.
Compare the positive numbers:
Finally, compare 0.8 and 0.9. Since 0.9 is larger, it comes last.
Therefore, the order from least to greatest is: -1.3, -1.2, 0.8, 0.9. This corresponds to option A.
