Answer:
$33.81
Step-by-step explanation:
Strawberries = $2.49 Per Pound (Bought 3)
Blueberries = $3.19 Per Pound (Bought 2)
Pineapples = $4.99 Per Pound (Bought 4)
So we have to multiply each price with the number of fruits bought.
So, For Example, Strawberries: $2.49 × 3 = $7.47
After you did all three individually, add them all up.
Strawberries : $7.47
Blueberries : $6.38
Pineapple : $19.96

Let us suppose Christmas lights have a total of 120 bulbs in a set, each with a 99.9% reliability rating. What is the probability that a set all works?
The probability that a set of all bulbs work is 0.88.
What is called as the total probability?The total probability rule (also known as the Law of Total Probability) divides probability calculations into discrete steps.
It's used to calculate the probability of an event, A, once you don't know enough about A's probabilities to do so directly. Instead, you use a related event, B, to calculate the probability of A.Two events are considered independent if a occurrence of one does not affect the likelihood of occurrence of the other.Now, as per the question;
The total number of bulbs be 120 and each bulb is working as independent event.
The reliability of each bulb is 99.9% = 0.999
Let 'p' the probability the bulb will work.
The probability that all will work = p¹²⁰
The probability that all will work = (0.999)¹²⁰ = 0.886
Thus, the probability that all bulb will work is 88.6%.

Waim want to buy weet to ditribute on hi birthday. He want to give 3 weet to each of
hi 28 friend and have 10 weet extra. How hould he calculate the number of weet to
buy?
The number of weet to buy is 84.
We have amount given to one friend and we need to find number of weet given to all of his friends. We use unitary methods to calculate the number of weets.
Let total number of weet be X
Number of weet given to 1 friend = 3
Number of weet given to 28 friend = 28 X 3
= 84
Therefore X = 84
84 weet will be distributed among 28 friend.
Wasim wants 10 weet extra
So, total number of wee he will purchase =
Total weet given to his 28 friends + total extra weet
= 84 + 10
= 94

let f(x)=10(3)2x−2. evaluate f(0) without using a calculator. do not include f(0) in your answer.
If function f(x)=10(3)2x−2, then f(0) = 10/9.
Explanation:
Step 1: To evaluate f(0), we can substitute x with 0 in the given function f(x) = 10(3)^(2x-2).
f(0) = 10(3)^(2(0)-2) = 10(3)^(-2)
Step 2: Now we know that a^(-n) = 1/a^n. So, we can rewrite 3^(-2) as 1/3^2.
f(0) = 10 * (1/3^2) = 10 * (1/9)

A room is 3 times longer than its breadth and its perimeter is 32 m .Find the cost of carpeting its floor with carpet 80cm wide at Rs.12 per metre
Answer:
At Rs of 12/m this would cost approx 12*60 = Rs 720
Step-by-step explanation:
2* (Length + breadth) = perimeter = 32
Length + breadth = 3* breadth + 1* breadth = 4* breadth
Substituting gives the equation
2*(4*breadth) = 8*breadth = 32
Therefore breadth = 32/8 = 4 metres
If breadth is 4 metres then length = 4 * 3 = 12 metres
So the room is 4m x 12m, which gives an area of 48m2
If the carpet is 0.8m wide and you are laying it lengthwise then you will need, 4/0.8 = 5 strips and as each strip is the length of the room (12m) the total length of 0.8m wide carpet required is 5 strips * 12m length = 60m
At Rs of 12/m this would cost approx 12*60 = Rs 720

b can be written as a linear combination of a1 and a2 with weights x1 = 3 and x2 = 3.
Thus, (b) x1 = 3, x2 = 3 is the right response.
To determine whether b can be written as a linear combination of a1 and a2, we need to find weights x1 and x2 such that x1a1 + x2a2 = b.
Here a1 = [2 6 -4], a2 = [-2 6 6], and b = [0 36 6], we have the following system of equations:
2x1 - 2x2 = 0
6x1 + 6x2 = 36
-4x1 + 6x2 = 6
Solving for x1 and x2, we have:
From the first equation, we can write x1 = x2.
Substituting x1 = x2 in the second equation, we get:
6x1 + 6x1 = 36
12x1 = 36
x1 = 3
Since x1 = x2, we have x2 = 3 as well.
Now, substituting the values of x1 and x2 in the third equation, we get:
-4(3) + 6(3) = 6
-12 + 18 = 6
6 = 6
Since the system is consistent, there is a solution. Therefore, b can be written as a linear combination of a1 and a2 with weights x1 = 3 and x2 = 3.

Dion's study suffers from selection bias as his sample of individuals on the beach in Miami may not be representative of the entire population's affinity for warm weather.
This is because he is only sampling residents of Miami, Florida, who are on the beach.

Mali spent exactly 2 hours at home doing her favorite things : reading and playing her guitar . Each chapter took her 30 minutes to read and each song took her 5 minutes to play.
What mathematical things can you say about how she spent her two hours?
If Mali read 2 chapters, how many songs did she play?
How many songs can Mali play in the time it takes her to read one chapter?
If Mali read more chapters than she played songs, how many chapters did she read?
Write and answer one more question about Malis activities.
When Mali spent 5 minutes playing each song, she played a total of 12 songs.
How to calculate the valueMali spent 2 hours at home, which is equivalent to 120 minutes. She spent 30 minutes reading each chapter, so she read a total of 120 / 30 = 4 chapters. She spent 5 minutes playing each song, so the number of songs she played can be found by subtracting the time she spent reading from the total time spent:
120 - (4 chapters x 30 minutes per chapter)
= 120 - 120
= 0 minutes
So, Mali did not play any songs during the 2 hours she spent at home.
If Mali read 2 chapters, then the total time she spent reading is 2 chapters x 30 minutes per chapter = 60 minutes. The remaining time she spent playing her guitar can be found by subtracting the time spent reading from the total time:
120 - 60 = 60 minutes
Since Mali spent 5 minutes playing each song, she played a total of 60 / 5 = 12 songs.

x-y=7
x² + y = 149
Answer
x = 12, y = 5
x = -13, y = -20
Step by step explanation:
You have two equations, and you have to find a way to merge them.
x - y = 7 —— {1}
From {1}, y = x - 7 —— {2}
x² + y = 149 —— {3}
Rep {2} in {3}
x² + y = 149
x² + (x-7) = 149
x² + x - 156 = 0
(x-12) (x+13) = 0
x = 12 and x = - 13
When x = 12, y = 12 - 7 = 5
(12, 5)
When x = - 13, y = - 13 - 7 = - 20

Find the exact length of the shadow cast by a 15 ft. lamp post when the angle of elevation of the sun is 60º. "We have a tan of 60º and the lamp post is 15 ft., so we are trying to find the length of the shadow as x."
The exact length of the shadow cast by the lamp post is 15√3 feet.
We can use the tangent function to solve this problem.
Let's call the length of the shadow x.
We have the angle of elevation of the sun as 60º and the height of the lamp post as 15 ft.
From trigonometry, we know that:
tan 60º = opposite / adjacent
In this case, the opposite side is the length of the shadow (x), and the adjacent side is the height of the lamp post (15 ft).
So we can write:
tan 60º = x / 15
We can simplify the equation using the value of tangent for 60º, which is √3. So we have:
√3 = x / 15
Multiplying both sides by 15, we get:
x = 15 ×√3
Therefore, the exact length of the shadow cast by the lamp post is 15√3 feet.

The manager of Lawn and Garden Services would like to estimate the proportion of her employees' time spent performing various gardening and lawn care activities. She has made 400 random observations of a typical worker, with the following results: Activity Time Observed Mowing 200 Trimming 80 Raking 40 Miscellaneous 80 If the manager wants to be 95. 44 percent confident that the true proportion of time spent mowing is within. 02 (plus or minus) of the sample proportion, what should be her sample size?
a. 400
b. 1,000
c. 1,600
d. 2,000
e. 2,500
The sample size should be e) 2,500.
To calculate the sample size needed for the manager's confidence interval, we need to use the formula for the margin of error:
Margin of error = z * (standard deviation of the sample proportion) / sqrt(sample size)
Given the sample data, the sample proportion of time spent mowing is 200 / 400 = 0.5.
Plugging in the values, we get:
Margin of error = 1.96 * sqrt(0.5 * 0.5 / 400) = 0.02
Rearranging the formula and solving for the sample size, we get:
Sample size = (z / margin of error)^2 * (sample proportion * (1 - sample proportion))
= (1.96 / 0.02)^2 * (0.5 * 0.5)
= 2500
So, the sample size needed for a 95.44 percent confidence interval with a margin of error of 0.02 is 2,500. The answer is option (e).

To find median of the following sequence (18, 26, 29, 18, 44) we will arrange them in ascending order
18 , 18 , 26 , 29 , 44 . . . . . . . . . .(1)
