Answer:
x= 1/27
Step-by-step explanation:
the correct answer is : X = 1/27
Answer:
- 1/2
Step-by-step explanation:
To solve for x in the equation 3^2x = 1/3, we can start by taking the logarithm of both sides with base 3:
log3 (3^2x) = log3 (1/3)
Using the logarithmic property logb (a^n) = n * logb (a), we can simplify the left side:
2x * log3 (3) = log3 (1/3)
Since log3 (3) = 1, we can simplify further:
2x = log3 (1/3)
To find the value of the logarithm on the right side, we can use the definition of logarithms: logb (a) = c if and only if b^c = a. Since 1/3 = 3^-1, we have:
2x = log3 (3^-1) = -1
Finally, to solve for x, we divide both sides of the equation by 2:
x = -1/2
So the solution to the equation 3^2x = 1/3 is x = -1/2.
Your school is going to start offering afterschool clubs they will be nine clubs to choose from to have clubs at least 23 students we will need to sign up for each one what is the least number of students that must sign up to have all nine clubs
At least number of students who must have signed up to have all nine clubs is equal to 207.
Number of clubs school going to start after school = 9 clubs
At least number of students need to sign up in each one of the club is equal to 23 students.
At least number of students need to sign up to have all in nine clubs is equal to :
At least number of student in 1 club > 23
⇒ At least number of student in 9 club > 23 × 9
At least number of student in 9 club > 207
Therefore, at least number of students need to signed up to have in all nine given clubs are 207 students.

10% of the next 10 people Liz sees would be expected to be wearing sandals.
Liz is recording what kinds of shoes people are wearing at the mall. sandals 2 sneakers 12 high heels 6 Considering this data.
We have to determine how many of the next 10 people Liz sees would you expect to be wearing sandals.
Since 12 out of the 20 people Liz has seen were wearing sneakers, and 6 were wearing high heels, then 2 must have been wearing sandals.
Then, Expect to be wearing sandals = Number of people wearing sandals/Total number of records
Expect to be wearing sandals = 2/20 × 100
Expect to be wearing sandals = 1/10 × 100
Expect to be wearing sandals = 10%,
So 10% of the next 10 people Liz sees would be expected to be wearing sandals.

find the lower quartile and the upper quartile of the data set
Answer:
Lower Quartile = 13 min; Upper Quartile = 27 min
Step-by-step explanation:
Since we have the median, we now separate the data equally to the left and right of the median.
Thus, on the left (lower) portion we have 10, 11, 13, 18, and 19. We see 13 is the middle term of these 5 values so 13 is the lower quartile (Q1).
Similarly, one the right (upper) portion, we have 22, 25, 27, 30, and 32. We see 27 is the middle term of these 5 values so 27 is the upper quartile (Q3)

Answer:
The flagpole is 15 ft tall.
Step-by-step explanation:
In this problem, we are asked to create a proportion of similar triangles to solve for the height of a flagpole.
1) Setting up the ProportionWe are given an equation with the proportion:
[tex]\dfrac{h}{6\text{ft}}=\dfrac{\square}{\square}[/tex]
We can fill in the blanks as follows:
[tex]\dfrac{h}{6\text{ft}}=\dfrac{25 \text{ft}}{10 \text{ft}}[/tex]
Notice that the heights of the triangles compared are both in the numerator, and the lengths of both triangles are in the denominator.
2) Solving the ProportionThen, to solve for the height of the flagpole, we can isolate the variable h in the proportion.
[tex]\dfrac{h}{6}=\dfrac{25}{10}[/tex]
↓ multiply both sides by 6
[tex]h = \dfrac{150}{10}[/tex]
↓ simplify the fraction
[tex]h = 15 \text{ ft}[/tex]
So, the flagpole is 15 ft tall.

What is area of a square?The quantity of square units required to completely cover a square is known as the area of a square. The territory that lies inside the confines of a flat item or a two-dimensional figure is generally referred to as the area. The measurement is made using square units, with square meters serving as the standard unit.
The Taj Mahal has an area of 9092.16 square meters (97,890.56 square feet). We utilise the formula for calculating the area of a square, which is length x width. The Taj Mahal's length and width are both 95.4 metres, therefore we just multiply these two values together. 9092.16 square meters = 95.4 × 95.4 square meters (97,890.56 square feet).

The Son has got his Crown On The pharaoh’s outfitters, ‘Cloaks and Crowns’, sell Cloaks and Crowns in 3 sizes – prince, king and emperor (in increasing size order). He wants to kit out his three sons for the forthcoming festival of Ra. Ahmose chooses a bigger cloak than Kamose, but a smaller crown than Thutmose. Both Thutmose’s cloak and crown are larger than Kamose’s, but the size of Thutmose’s crown matches the size of Kamose’s cloak. Which sizes did the pharaoh’s sons each get?
The only possible solution for system is A = 2, B = 1, and C = 3, which means Thutmose got the emperor size crown and cloak, Kamose got the prince size cloak and king size crown, and Ahmose got the king size cloak and prince size crown.
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
Let's us consider the sizes of the cloaks by C (prince), B (king), and A (emperor)
The sizes of the crowns by 1 (prince), 2 (king), and 3 (emperor).
Now let us write the following system of inequalities:
B > C
A > B
3 = C (Thutmose's crown matches Kamose's cloak)
2 > C
A > 3
A > 2 (Thutmose's crown is larger than the king size crown)
From the fifth inequality, we know that Thutmose's cloak is the largest of all three cloaks, so A must equal C.
Therefore, we can simplify the system of inequalities to:
B > C, A > B, C = 3, 2 > C, A > 3 and A > 2
Hence, the only possible solution for system is A = 2, B = 1, and C = 3, which means Thutmose got the emperor size crown and cloak, Kamose got the prince size cloak and king size crown, and Ahmose got the king size cloak and prince size crown.

−2x+y = 0 - −7x+3y = 2
To solve this system of linear equations, we need to find the values of x and y that make both equations true at the same time. One method to solve this is to use elimination or substitution.
First, let's rearrange the first equation:
y = 2x
Next, we can substitute y = 2x into the second equation:
-7x + 3y = 2
-7x + 3(2x) = 2
-7x + 6x = 2
-x = -2
So, x = 2.
Finally, we can use the first equation to find y:
y = 2x
y = 2 * 2
y = 4
So, the solution to the system of equations is (x, y) = (2, 4).
in a shipment of 66 vials, only 14 do not have hairline cracks. if you randomly select 4 vials from the shipment, what is the probability that all 4 of the selected vials have hairline cracks?
that the probability of selecting 4 vials with hairline cracks is approximately 0.0375, or 3.75%
We can solve this problem using the hypergeometric distribution, which is used when sampling without replacement from a finite population. In this case, we have a population of 66 vials, out of which 14 are good (do not have hairline cracks) and 52 are bad (have hairline cracks). The probability of selecting all 4 bad vials (with hairline cracks) can be calculated as follows: P(4 bad vials) = (number of ways to choose 4 bad vials) / (total number of ways to choose 4 vials)
The number of ways to choose 4 bad vials from 52 is: C(52,4) = 52! / (4! × (52-4)!) = 270725
The total number of ways to choose 4 vials from 66 is: C(66,4) = 66! / (4! × (66-4)!) = 7219420
Therefore, the probability of selecting all 4 bad vials is: P(4 bad vials) = 270725 / 7219420 = 0.0375
This means that the probability of selecting 4 vials with hairline cracks is approximately 0.0375, or 3.75%

Find the 43rd term.
The given sequence appears to be an arithmetic sequence, as the difference between consecutive terms is 9. To find the 43rd term, we can use the formula for the nth term of an arithmetic sequence:
a_n = a_1 + (n - 1)d
where a_n is the nth term, a_1 is the first term (11 in this case), n is the term number (43 in this case), and d is the common difference (9 in this case).
Plugging in the values, we get:
a_43 = 11 + (43 - 1) * 9
a_43 = 11 + 42 * 9
a_43 = 11 + 378
a_43 = 389
So the 43rd term of the sequence is 389.
