the probability that a student selected in our class will pass mathematics test is 2/3 how many students are likely to feel mathematics in the art class with 69 students
Answers
Out of 69 students in the art class, around 23 are expected to fail the mathematics test, assuming the probability of passing given is 2/3.
To determine how many students are likely to fail mathematics in the art class, we need to use the given probability of passing the mathematics test, which is 2/3.
First, let's find the probability of failing the mathematics test. Since passing and failing are complementary events (i.e., if the probability of passing is p, then the probability of failing is 1 - p), we can calculate the probability of failing as 1 - 2/3, which simplifies to 1/3.
Now, let's consider the art class, which has a total of 69 students. If the probability of failing mathematics is 1/3, then approximately 1/3 of the students in the art class are likely to fail the mathematics test.
To find the number of students likely to fail, we multiply the probability of failing (1/3) by the total number of students in the art class (69).
(1/3) * 69 ≈ 23
Therefore, approximately 23 students are likely to fail mathematics in the art class of 69 students based on the given probability of passing the mathematics test.

Answers
The answer is earthquakes: open up large cracks in Earth’s crust tsunamis: erosion of beaches.
What is tsunamis?
Giant waves that are brought on by ocean floor movement are known as tsunamis. Landslides, underwater volcanic eruptions, earthquakes, and even meteorite collisions can cause the ocean floor to tremble. These are often referred to as seismic sea waves, albeit they are sometimes misidentified as tidal waves. A tsunami is a set of waves that are caused by a disturbance in the ocean or another body of water, such as an earthquake, landslide, volcanic eruption, or meteorite strike.
The water above shifts up or down as a result of undersea earthquakes, which often take place along tectonic plate borders. Earth’s crust tsunamis: erosion of beaches.
Hence, earthquakes: open up large cracks in the Earth’s crust tsunamis: and erosion of beaches.

Newly purchased automobile tires of a certain type are supposed to be filled to a pressure of 30 psi. Let μ denote the true average pressure. Find the P-value associated with each of the following given z statistic values for testing H0: μ = 30 versus Ha: μ 30 when σ is known. (Give the answers to four decimal places.)
calculate for each
(a) z = 2.30
(b) z = -1.7
Answer:
a
\(p-value = 0.021448\)
b
\(p-value = 0.08913\)
Step-by-step explanation:
From the question we are told that
The population mean is \(\mu = 30 \ psi\)
The null hypothesis \(H_o : \mu = 30\)
The alternative hypothesis is \(H_a : \mu \ne 30\)
Considering question a
Here the test statistics is (a) z = 2.30
From the z table the probability of (Z > 2.30) is
\(P(Z > 2.30 ) = 0.010724\)
Generally the p-value is mathematically represented as
\(p-value = 2 * P(Z > 2.30 )\)
=> \(p-value = 2 * 0.010724\)
=> \(p-value = 0.021448\)
Considering question b
Here the test statistics is (a) z = -1.7
From the z table the probability of (Z < -1.7) is
\(P(Z < -1.7 ) = 0.044565\)
Generally the p-value is mathematically represented as
\(p-value = 2 * P(Z < -1.70 )\)
=> \(p-value = 2 * 0.044565\)
=> \(p-value = 0.08913\)

show that f(x) is riemann integrable over [0, 1] if and only if f(x) is continuous almost everywhere
Answers
The statement that "f(x) is Riemann integrable over [0, 1] if and only if f(x) is continuous almost everywhere" is not entirely correct. While continuity almost everywhere is a sufficient condition for Riemann's integrability, it is not a necessary one.
A function is Riemann integrable over an interval if and only if it is bounded and has a finite number of discontinuities in that interval, which are called "jump discontinuities". So, if a function is continuous almost everywhere, it is certainly Riemann integrable.
On the other hand, there are functions that are Riemann integrable but not continuous almost everywhere. For example, the function f(x) = x on [0, 1] is Riemann integrable, but it is not continuous at x = 0 and x = 1, so it is not continuous almost everywhere.
Therefore, we can conclude that continuity almost everywhere is a sufficient condition for Riemann's integrability, but not a necessary one.

Formula
Answers
The roots of the quadratic equation are (3 ± √(-19) / 2. Hence, the polynomial has no real roots.
What are the roots of the equation :The roots of an equation are the values of the variable that make the equation equal to zero. In a quadratic equation of the form ax²+bx+c=0, the roots can be found by using the quadratic formula:
x = (-b ± √(b²-4ac)) / 2a
Here we have
The quadratic equation x²- 3x+7
To find the roots of the quadratic equation x²-3x+7, we can use the quadratic formula, which states that the roots are given by:
x = (-b ± √(b²-4ac) / 2a
where a, b, and c are the coefficients of the quadratic equation.
In this case, we have a = 1, b = -3, and c = 7.
Substituting these values into the formula, we get:
x = (-(-3) ± √[ (-3)² - 4(1)(7) ] / 2(1)
x = (3 ± √(9 - 28)) / 2
x = (3 ± √(-19) / 2

7. Are the two triangles similar? How do you know? I need this answered quick plz
Answers
Answer:
Yes, by the angle angle rule.
Step-by-step explanation:
In the first triangle,
m<C=60 degrees, and m< D=53 degrees. You know that the sum of angles in a triangle add up to 180 degrees, so solve for E. m<E= 67 degrees.
In the second triangle,
m<F=60 degrees and m<H=67 degrees.
Since both triangle have two congruent angles, you can say that the two triangles are similiar by the AA rule.
Both triangle CDE and triangle FGH are similar to each other.
Similar figures
Two figures are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion. All the corresponding angles of similar figures are congruent.
∠C + ∠D + ∠E = 180° (angles in a triangle)
60 + 53 + ∠E = 180
∠E = 67°
∠C = ∠F, ∠D = ∠G, ∠E = ∠H, hence both triangles are similar.

Given:
\(3^{x+4}=243\)First, we need to express 243 as a number with base 3 raised to a certain exponent.
From this, if we take 3 to the fifth power, we will get the value of 243
\(3^5=243\)Now, we can rewrite the given equation as
\(3^{x+4}=3^5\)Now that we have the same base for both sides of the equation, we can now focus on solving the exponents for the value of x.
\(x+4=5\)*Solve for x
\(x=5-4\)\(x=1\)Therefore, the value of x = 1.
