The probability that it will rain at least one day is 0.375.
What is binomial probability?The binomial distribution model allows us to calculate the likelihood of observing a specified number of "successes" when the process is repeated a certain number of times.
Let :
Sunny = S
Rainy = R
The probability that it rains on at least one day can be get using the binomial probability relation :
[tex]P=nCx*p^x*q^{n-x}[/tex]
[tex]P_{x=1}=3C1*0.5^1*0.5^2[/tex]
[tex]P_{x=1}=0.375[/tex]
Thus, the probability here is 0.375.

Read this passage about the invention of the modern seismograph.
Using knowledge of earthquake waves and motion, John Milne invented the modern seismograph in 1880. This device records the movements of different waves created by an earthquake as they move through Earth's interior and across its surface. This data allowed scientists to discover more about Earth's interior such as the fact that the core is solid.
Question
What did the invention of the seismograph allow scientists to discover?
Responses
1. There are different types of earthquake waves.
2. Earthquakes can be predicted.
3. Earth's core is solid.
4. Earthquake damage is due to waves of energy.
The invention of the seismograph allow scientists to predict the earthquake. The correct option is 2.
What is seismograph?Seismographs are devices that record the movement of the ground during an earthquake. They are installed in the ground all over the world as part of a seismographic network.
Sensitive seismographs, which magnify ground motions, can detect strong earthquakes from anywhere on the planet.
Seismograph stations' data can be used to determine the time, location, and magnitude of an earthquake.
The seismologist can tell how far away the earthquake was and how powerful it was by studying the seismogram.
This record does not tell the seismologist where the epicenter was, only that the earthquake occurred a certain number of miles or kilometers away from that seismograph.
Thus, the correct option is 2.

What is the positive difference between the circumference of circle B and the circumference of circle A?
The positive difference between the circumference of circle B and the circumference of circle A is 1. Thus, the correct option for this question is A.
What is the circumference of the circle?The circumference of the circle may be defined as the total stretch of the boundary of the circle. The formula for calculating the circumference of the circle is as follows:
C = 2πr.where, C = circumference of the circle.
π = the constant pie.
r = radius of the circle.
According to the question,
The circumference of the circle A = 2π (r+1).
The circumference of the circle B = 2π (r+2).
∴The positive difference between the circumference of circle B and the circumference of circle A is as follows:
2π (r+2) - 2π (r+1) = 1.
Therefore, the positive difference between the circumference of circle B and the circumference of circle A is 1. Thus, the correct option for this question is A.

If the expression n² - 2n - 8 represents the net profit
on the sale of n units of a product, which of the
following values represents the number of units
sold for which the net profit equals 0 dollars?
A) 2
B) 4
C) 6
D) 8
Option B) 4 is the number of units of product sold to get a profit of 0 dollars when the algebraic expression for profit is given.
the expression for net profit is [tex]n^{2}[/tex] -2n - 8 for the sale of n units of a product
If net profit equals 0 then
[tex]n^{2}[/tex] - 2n -8 =0
⇒[tex]n^{2}[/tex] - 4n + 2n - 8= 0
⇒ n ( n - 4) + 2(n - 4) = 0
⇒(n + 2)(n - 4) = 0
∴ n+ 2 = 0
⇒ n = -2
OR
n - 4 = 0
⇒ n = 4
As the number of units of product sold cannot be negative, thus n cannot have a value of -2
The only remaining value is n = 4
Thus, 4 units of the product are sold for 0 dollars profit. Option B) 4 is the correct answer.

An even number is a number that can be divided into two equal groups. An odd number is a number that cannot be divided into two equal groups.
Hope this helps!
The even numbers in the above wide variety sequence are 2, 4, 6, 8, 10, 12, 14, sixteen, 18, and 20.
These integers are divisible by way of 2, and their department by using 2 does not result in a remainder.
Even numbers have an ending digit this is both 0, 2, 4, 6, or 8. They can be divided into two same halves and are distinguished by being equally divisible by way of 2.
The sequence's abnormal numbers, however, are 1, three, five, 7, 9, 11, 13, 15, and 19.
These integers always bring about a remainder of one, even when divided by 2, due to the fact they can't be divided through two calmly. Odd numbers can be diagnosed by using their ending digit, that is both 1, three, 5, 7, or 9.
Thus, even numbers are divisible with the aid of 2 and have an ending digit of zero, 2, four, 6, or 8, even as odd numbers can not be divided frivolously through 2 and feature an finishing digit of 1, 3, 5, 7, or 9.

What is the length of BD?
In the given figure, the length of BD is 14. The correct option is A.
What is the length?Length is the measurement of the extent of something from one end to another, end. The SI unit of length is a meter (m).
Given, that AB is twice the length of BC
BC = CD
DE is a triple of CD
The length of AE is 19
Let's assume BC and CD = x
We have to calculate the length of the CD.
AB = 2x
DE = 3x
Putting the values:
2x + 3x = 49
7x = 49
x = 49 / 7
x = 7
BC and CD = x
7x + 7x = 14x

Because it aids in comprehending measurements when the data is scattered, standard deviation is significant. The standard deviation of the data will be higher the more evenly dispersed the data is.
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. The best measure of dispersion is standard deviation since it most closely resembles the ideal measure of dispersion. 1. The Standard Deviation is the main tenet of statistical theory. Comparing the variability of two or more sets of data is useful.
