Answer:

1,600 seats in the theater

Step-by-step explanation:

well it seems like each row is being increased by 8 seats each time.

we start with 4 seats in the 1st row. 12 in the 2nd. and 20 in the 3rd. I will make a chart showing you how many seats are in each row.

4th row - 28  5th row - 36   6th row - 44   7th row - 52   8th row - 60   9th - 68   10th - 76   11th - 84    12th - 92   13th - 100    14th - 108   15th - 116   16th- 124    17th - 132   18th - 140    19th - 148    20th - 156

if we add these all together you will get 1,600

Answer:

1600 seats

Explanation:

1st row = 4 seats, 2nd row = 12 seats, 3rd row = 20 seats

This is arithmetic progression with first term (a) being 4 and common difference (d) of 8 and total term (n) of 20.

Sum of arithmetic series:

\(\sf S_n = \dfrac{n}{2} ( 2a + (n-1)d)\)

insert values

\(\sf S_{20} = \dfrac{20}{2} ( 2(4) + (20-1)8)\)

\(\sf S_{20} = 1600\)

Answer:

x = -3 y = -8 (-3,-8)

Step-by-step explanation:

first you would subsitute the y with (2x-2) in -3x+4y=-23 as y=2x-2

giving you-3x+4(2x-2)=-23

next you distribute the 4 to (2x-2) leaving you with -3x+8x-8=-23

then add -3x+8x to get 5x, having 5x-8=-23

add 8 to both sides canceling out 8 on one side and adding 8 to the other leaving you with 5x=-15 then you divide 5 from 5x to both sides leaving you with x = -3

next is y since you have x you would substitute the x in y=2x-2 with -3 getting y=2(-3)-2 then you multiply the 2 and -3 so you have y=-6-2 then you subtract those getting y = -8

Ellen can make a maximum of 6 batches of Cardamom cookies with her 2 fluid ounces of cardamom.

Ellen has 2 fluid ounces of cardamom in a jar. Her recipe requires 3/10 of a fluid ounce of cardamom for each batch of cardamom cookies.

We can use division to find the number of batches of cardamom cookies that Ellen can make with all of her cardamom:

2 fluid ounces ÷ (3/10 fluid ounce per batch) = (2/1) ÷ (3/10)

= (2/1) x (10/3)

= 20/3

= 6 2/3

Therefore, Ellen can make 6 batches of cardamom cookies with her 2 fluid ounces of cardamom, with 2/3 of a batch remaining.

Since she cannot make a fraction of a batch, Ellen can make a maximum of 6 batches of cardamom cookies with her 2 fluid ounces of cardamom.

The rule for the reflection is that when reflecting over the x-axis, the x-coordinate remains the same but the y-coordinate changes to the opposite sign.

The x-coordinate must remain constant when reflecting across the x-axis, but the y-coordinate must change to the opposite sign. When reflecting over the y-axis, the y-coordinate remains the same but the x-coordinate changes to the opposite sign.

A figure is transformed into a reflection by a transformational process. In a point, a line, or a plane, figures can be reflected. The image and preimage coincide when reflecting a figure in a line or a point.

Every point of a figure is translated to an image across a fixed line via a reflection. The fixed line is referred to as the reflection line.

The given equation is f(t) = 222(1.49)t. We are supposed to convert this equation to the form  Here, the base is 1.49 and the value of a is 222.

To convert this equation to the form f(t) = aet, we use the formulae for exponential functions:

f(t) = ae^(kt)

When k is a constant, then the formula becomes:

f(t) = ae^(kt) + cmain answer:

f(t) = 222(1.49)t can be written in the form

f(t) = aet.

The value of a and e are given by:

:So, we can write

f(t) = 222e^(kt)

Here, a = 222, which means that a is equal to the initial amount of substance.

e = 1.49,

which is the base of the exponential function. The value of e is fixed at 1.49.k is the exponential growth rate of the substance. In this case, k is equal to ln(1.49).

f(t) = 222(1.49)t

can be written as

f(t) = 222e^(kt),

where k = ln(1.49).Therefore,

f(t) = 222(1.49)t

can be written in the form f(t) = aet as

f(t) = 222e^(kt)

= 222e^(ln(1.49)t

)= 222(1.49

We can use a priority queue to keep track of the k most frequent strings. The priority queue should be sorted by the frequency of the strings, and in case of ties, we should sort by lexicographical order.

Here's the step-by-step algorithm to solve the problem:

1. Create a hash map to count the frequency of each string in the array.
2. Create a priority queue and define a custom comparator function that compares strings based on their frequency and lexicographical order.
3. Iterate over the keys of the hash map and add each string to the priority queue.
4. Pop the top k strings from the priority queue and add them to the result array.
5. Return the result array sorted in descending order of frequency.

Here's the Python code that implements this algorithm:

```
import heapq
from collections import defaultdict

def topKFrequent(words, k):
   freq = defaultdict(int)
   for word in words:
       freq[word] += 1
   
   pq = []
   for word, count in freq.items():
       heapq.heappush(pq, (-count, word))
   
   res = []
   for i in range(k):
       res.append(heapq.heappop(pq)[1])
   
   return sorted(res, key=lambda x: (-freq[x], x))
```

In this code, we use a defaultdict from the collections module to count the frequency of each string. We then use a heap (implemented as a list) to keep track of the k most frequent strings. The -count value is used as the first element of each tuple in the heap, so that we can sort the strings by frequency in descending order. The second element of each tuple is the string itself, which is used to break ties in case of equal frequency. Finally, we sort the result array based on the frequency and lexicographical order using the sorted function and a lambda function.

The mean of the probability distribution for the number of 5's obtained in this experiment is 5.

To find the mean of the probability distribution for the number of 5's obtained in rolling a fair die 30 times, we'll use the terms probability, binomial distribution, and expected value.

A fair die has 6 sides, so the probability of rolling a 5 is 1/6. The experiment involves rolling the die 30 times, making it a binomial distribution problem. In a binomial distribution, the expected value (mean) can be calculated using the formula:

Mean = n * p

where n is the number of trials (30 rolls in this case), and p is the probability of success (rolling a 5, which has a probability of 1/6).

Mean = 30 * (1/6) = 5

So, the mean of the probability distribution for the number of 5's obtained in this experiment is 5.

If  a random variable T is Exponential with u = 102 then the probability that T is less than or equal to 153 is 0.632

If T is an exponential random variable with parameter u, then the probability density function of T is given by:

\(f(t) = (1/u) \times e^(^-^t^/^u^)\) for t ≥ 0

The cumulative distribution function (CDF) of T is given by:

F(t) = P(T ≤ t)

= ∫[0, t] f(x) dx

\(= 1 - e^(^-^t^/^u^)\) for t ≥ 0

In this case, we are given that T is Exponential with u = 102.

To find P(T ≤ 153), we can use the CDF formula with t = 153:

P(T ≤ 153) = F(153)

= \(1 - e^(^-^1^5^3^/^1^0^2^)\)

P(T ≤ 153) = 0.632

Therefore, the probability that T is less than or equal to 153 is 0.632.

the form of a right rectangular prism, which means it has a rectangular base and all its sides are perpendicular to each other. the height of the water tank is approximately  \(1.5\) feet when rounded to the nearest tenth.

The volume of a right rectangular prism is given by the formula:

Volume = Length x Width x Height

We know that the tank can hold 136 cubic feet of water when it is full, and we are given the values of the length and width of the tank. So, we can solve for the height of the tank as follows:

\(136 = 10.5 \times 9.2 \times\) Height

Dividing both sides by  \((10.5 \times 9.2)\) , we get:

Height \(= \frac{136}{(10.5 \times 9.2)} = 1.526 ft\) (rounded to three decimal places)
