The average distance from Earth to the Moon is approximately 384,400,000 kilometers.
What is the average distance, in kilometers, from Earth to the Moon written in scientific notation?
A 3.844 x 10^4 kilometers
B 3.844 x 10^5 kilometers
C 3.844 x 10^7 kilometers
D 3.844 x 10^8 kilometers
9514 1404 393
Answer:
D. 3.844 × 10^8 kilometers
Step-by-step explanation:
To write the number in scientific notation, put a decimal point after the most significant digits and write the rest of the significant digits after that. Multiply the number by the power of 10 that tells how many digits are between the most significant digit and the decimal point.
Here, the number has 8 digits between the most-significant digit (3) and the decimal point. Any trailing zeros are assumed to be not significant when the number is written without a decimal point. So, the number is written ...

Paralelas
b.
Semirectas
c.
Secantes
d.
Perpendiculares
Las dos rectas que se cortan formando un ángulo de 135° son secantes. (Opción: C)
Las dos rectas en cuestión no pueden ser paralelas pues sus pendientes son distintas y, por consiguiente, se intersecan en algún lugar del plano.
Tampoco pueden ser semirrectas pues el enunciado indica que existen dos rectas y las rectas no tienen principio ni fin.
Mucho menos pueden ser perpendiculares, pues el ángulo es distinto a 90°.
En consecuencia, las dos rectas que se cortan formando un ángulo de 135° son secantes. (Opción: C)

A manufacturing process is designed to produce bolts with a 0.75-inch diameter. Once each day, a random sample of 36 bolts is selected and the bolt diameters recorded. If the resulting sample mean is less than 0.730 inches or greater than 0.770 inches, the process is shut down for adjustment. The standard deviation for diameter is 0.04 inches. What is the probability that the manufacturing line will be shut down unnecessarily
Using the normal distribution and the central limit theorem, it is found that there is a 0.0028 = 0.28% probability that the manufacturing line will be shut down unnecessarily.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n have standard deviation given by [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
Mean of 0.75 inches, thus [tex]\mu = 0.75[/tex].Standard deviation of 0.04 inches, thus [tex]\sigma = 0.04[/tex]Sample of 36, thus [tex]n = 36, s = \frac{0.04}{\sqrt{36}} = 0.0067[/tex].The probability of being shutdown is the probability of a sample mean less than 0.73 inches or more than 0.77 inches. They are the same distance to the mean(0.02), thus, considering the Central Limit Theorem:
[tex]z = \frac{0.02}{s}[/tex]
[tex]z = \frac{0.02}{0.0067}[/tex]
[tex]z = 2.99[/tex]
The probability is P(|z| > 2.99), which is 2 multiplied by the p-value of z = -2.99.
z = -2.99 has a p-value of 0.0014.
2(0.0014) = 0.0028
0.0028 = 0.28% probability that the manufacturing line will be shut down unnecessarily.

What is the equation of the line -3 x - 2 y= 30 in slope intercept form
Answer:
[tex]y=-\frac{3}{2}x-15[/tex]
Step-by-step explanation:
The slope intercept form is y=mx+b, where m is the slope and b is the y intercept.
So, all we have to do is make y the subject.
[tex]-3x-2y=30\\-2y=3x+30\\y=\frac{3x+30}{-2} \\y=-\frac{3}{2}x-15\\\\[/tex]
Answer:
y = (3/2)x - 15
Step-by-step explanation:
For it to be in slope intercept form, y has to be the subject of the equation, so it's a simple matter of rearranging the equation.
Original:
-3x - 2y = 30
and we want y to be the subject, so we start moving terms:
-3x = 30 + 2y
-3x - 30 = 2y
now it's just a matter of dividing both sides by 2 to give y as the subject
(-3/2)x - 15 = y
y = (-3/2)x - 15

A normal conversation is about 10^7 times the threshold of hearing. Compute the intensity level (in decibels) for a normal conversation.
Answer:
70
Step-by-step explanation:
The sound of a normal conversation 3 is times intense than the sound of a computer.
What is sound intensity?It is the energy flow per unit area. It refers to the product of pressure and velocity of particles in a fluid medium, which is equivalent to the power received per unit area.
Let us say the sound intensity of the quietest noise a person can hear is 60 decibels. So the sound intensity of computer is 20 decibels.
Sound intensity of a normal conversation/ computer sound, will be:
[tex]SI=\frac{60}{20} =3[/tex]
Therefore, the sound of a normal conversation 3 is times intense than the sound of a computer.
