a safety inspector found flaws in 3 out of 540 lamps built in a factory what is the probability that the next lamp she expects is flawed.
Answers
The probability that the next lamp safety inspector expects will be defective is 1/180.
What is probability?Probability is a branch of mathematics that deals with numerical descriptions of how likely an event is to occur or how likely a proposition is to be true. The probability of an event is a number between 0 and 1, where 0 indicates the event's impossibility and 1 indicates certainty.Formula: P = favourable events/Total events
Put the values in the formula and solve as follows:
P = favourable events/Total eventsP = 3/540P = 1/180Therefore, the probability that the next lamp safety inspector expects will be defective is 1/180.

The longest high-voltage line in the world, NorNed, connecting the Netherlands and Norway, is 580 km long. The length of the pipeline, which costs 600 million euros, 47 thousand tons, is also gigantic. Imagine a wire going around the Earth along the equator. By how many meters should this pipeline be extended if we want to run it 10 kilometers higher at each point? During the solution, you can calculate that the Earth is a sphere with a radius of 6371 kilometers. Round your answer to a whole value!
Answers
the pipeline needs to be extended by approximately 40,020 km.
What are Distance?
The distance an object travels in athe predetermined period of time. Here is a word equation that illustrates the connection between space, speed, and time: velocity is calculated by dividing the total Distance traveled by the journey time.
To find the additional length of the pipeline needed to raise it by 10 km at each point, we need to calculate the length of the new circle formed by the pipeline.
The radius of the Earth is 6371 km, and we want to raise the pipeline by 10 km at each point. This means that the new radius of the Earth will be 6371+10 = 6381 km.
The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. So the circumference of the new circle formed by the pipeline will be:
C = 2π(6381) = 40,075 km
The original length of NorNed is 580 km. To find out how many times longer the new pipeline needs to be, we divide the new circumference by the original length:
40,075 km / 580 km ≈ 69.2
So the pipeline needs to be extended by approximately 69 times its original length.
To find the additional length of the pipeline needed, we subtract the original length of 580 km:
69 × 580 km = 40,020 km
Therefore, the pipeline needs to be extended by approximately 40,020 km.

Customer pays $0.035 per minute for local calls, if the customer made 60 local calls that all lasted 3 minutes, how much will the customer pay?
Answers
The customer will pay $6.30 for the 60 local calls that all lasted 3 minutes.
To find out how much the customer will pay, we need to calculate the total cost for all the local calls.
Step 1: Calculate the total number of minutes for all the calls
Since the customer made 60 local calls and each call lasted 3 minutes, we can multiply 60 by 3 to get the total number of minutes.
60 calls * 3 minutes/call = 180 minutes
Step 2: Calculate the total cost for all the minutes
The customer pays $0.035 per minute for local calls. To find the total cost, we can multiply the total number of minutes by the cost per minute.
180 minutes * $0.035/minute = $6.30

Hey there!
The formula for feet to inches is to simply multiply the length value by 12.
So, multiply 140 by 12.
I believe your answer would be 1680 inches.

Answer:
140 feet is 1680 inches. Don't forget to put your units in; your teacher may dock off points for forgetting to put in the unit.
Step-by-step explanation:
A foot is 12 inches, so you must multiply 140 by 12.

Find the time, in seconds, it takes from the moment the soccer ball is kicked until it returns to the ground.
2. The height of a soccer ball that is kicked from the ground can be approximated by the function:
y = -16x^2 + 64x
where y is the height of the soccer ball in feet x seconds after it is kicked. What is the soccer ball's maximum height in feet?
Answers
Answer:
2. \(\displaystyle 64\:feet\)
1. \(\displaystyle 5\:seconds\)
Step-by-step explanation:
2. Sinse we do not have a y-intercept [C-value in this case], we have to use a part of the quadratic formula to solve for x, and rewrite this equation in Vertex Form, with \(\displaystyle [h, k]\) as the vertex point. Observe:
\(\displaystyle -\frac{b}{2a} = x \\ \\ -\frac{64}{2[-16]} = \frac{-64}{-32} = 2\)
Now, keep in mind that \(\displaystyle -h\) in the vertex formula, \(\displaystyle y = a[x - h]^2 + k,\) gives you the OPPOSITE TERMS OF WHAT THEY REALLY ARE, so in this case, sinse 2 is already positive, you do not need to alter its operation sign. With this being stated, you should already have this:
\(\displaystyle y = -16[x - 2]^2\)
Now, to find k, all you have to do is plug 2 into the TOP equation to get your maximum height:
\(\displaystyle -16[2]^2 + 64[2] = -16[4] + 128 = -64 + 128 = 64 \\ \\ \\ y = -16[x - 2]^2 + 64\)
Therefore, sinse 64 is your k-value, 64 feet is indeed your maximum height.
1. Simply factour the quadratic equation:
\(\displaystyle y = -18x^2 + 90x \\ 0 = -18x[x - 5] \\ \\ 5, 0 = x\)
In this case, from a height of sixty-four feet, it is IMPOSSIBLE for the football to hit the ground in zero seconds, therefore the ball will reach the ground in 5 seconds, which makes alot more sence.
I am joyous to assist you at any time.

a dilation has center (0,0). Find the image of the point L(-4,0) for the scale factor 7.
Answers
The image of the point L(-4,0) after a dilation with a center of (0,0) and a scale factor of 7 is the point L'(-28,0).
A dilation with a center of (0,0) and a scale factor of 7 means that every point in the plane will be multiplied by a factor of 7 from the origin.
To find the image of the point L(-4,0) after a dilation with a center of (0,0) and a scale factor of 7, we can simply multiply the coordinates of L by the scale factor.
The coordinates of the image point L' will be:
L' = (-4 × 7, 0 × 7) = (-28, 0)
Therefore, the image of the point L(-4,0) after a dilation with a center of (0,0) and a scale factor of 7 is the point L'(-28,0).

James wants to have earned $6,180 amount of interest in 28 years. Currently he finds
that his annual interest rate is 6.12%. Calculate how much money James needs to invest
as his principal in order to achieve this goal.
Answers
Answer:
$3606.44
Step-by-step explanation:
The question asks us to calculate the principal amount that needs to be invested in order to earn an interest of $6180 in 28 years at an annual interest rate of 6.12%.
To do this, we need to use the formula for simple interest:
\(\boxed{I = \frac{P \times R \times T}{100}}\),
where:
I = interest earned
P = principal invested
R = annual interest rate
T = time
By substituting the known values into the formula above and then solving for P, we can calculate the amount that James needs to invest:
\(6180 = \frac{P \times 6.12 \times 28}{100}\)
⇒ \(6180 \times 100 = P \times 171.36\) [Multiplying both sides by 100]
⇒ \(P = \frac{6180 \times 100}{171.36}\) [Dividing both sides of the equation by 171.36]
⇒ \(P = \bf 3606.44\)
Therefore, James needs to invest $3606.44.
