The correct calculation to find the probability that x is less than 2 is:

d. P [z < (2 - 2.3 / (1.3/√40))]

We know that the distribution of monthly bonuses earned by all employees last year has mean 2.3 and standard deviation 1.3.

Since we have a sample of size 40, we can use the central limit theorem to approximate the distribution of the sample mean x with a normal distribution with mean 2.3 and standard deviation 1.3/√40.

To find the probability that x is less than 2, we need to find the z-score corresponding to x = 2, given the distribution of x. We can do this using the formula:

z = (x - μ) / σ

where μ is the mean of the distribution of x (which is 2.3) and σ is the standard deviation of the distribution of x (which is 1.3/√40).

Plugging in the values, we get:

z = (2 - 2.3) / (1.3/√40)

z = -1.63

So, the probability that x is less than 2 is equal to the probability that z is less than -1.63, which is given by the standard normal distribution table as:

P [z < -1.63]

Therefore, the correct calculation to find the probability that x is less than 2 is:

d. P [z < (2 - 2.3 / (1.3/√40))]

Answer:

\(y = 1.4\)

Step-by-step explanation:

Given

\(y = width\)

\(x = length\)

\(y = 3;\ when\ x = 14\)

Required

Find y when x = 30

Being an inverse variation, we have:

\(y\ \alpha\ \frac{1}{x}\)

Convert the variation to an equation

\(y = \frac{k}{x}\)

First, we solve for k

Make k the subject to solve for k

\(k = xy\)

\(y = 3;\ when\ x = 14\)

So, the value of k is:

\(k = 14 * 3\)

\(k = 42\)

To solve for y when x = 30

Substitute 30 for x and 42 for k in \(k = xy\)

\(42 = 30 * y\)

Make y the subject

\(y = \frac{42}{30}\)

\(y = 1.4\)

The width of the rectangle would be as follows:

\(1.4\)  inches

Inverse proportion occurs when one value increases and the other decreases.

The width, \(y\), of a rectangle with a fixed area varies inversely with its length, \(x\).

So, \(y=\frac{k}{x}\) where \(k\) is the constant.

The width is \(3\) inches when the length is \(14\) inches.

So,

\(3=\frac{k}{14} \\k=42y=\frac{42}{x}\\Put x=30\)

Therefore, \(y=\frac{42}{30}=1.4\) inches

Thus, Width is \(\boldsymbol{1.4}\) inches when the length is \(30\) inches.

Answer:

p^3 - 7p^2q^2 + 2pq

Step-by-step explanation:

3pq +5p^2q^2 + p^3 = p^3 + 5p^2q^2 + 3pq

Let the number be x.

x + p^3 + 5p^2q^2 + 3pq + p^3 - pq

= 3p^3 - 2p^2q^2 + 4pq

x + p^3 + p^3 + 5p^2q^2 + 3pq - pq

= 3p^3 - 2p^2q^2 + 4pq

x + 2p^3 + 5p^2a^2 + 2pq

= 3p^3 - 2p^2q^2 + 4pq

x

= 3p^3 - 2p^2q^2 + 4pq - (2p^3 + 5p^2q^2 + 2pq)

= 3p^3 - 2p^2q^2 + 4pq - 2p^3 - 5p^2q^2 - 2pq

= 3p^3 - 2p^3 - 2p^2q^2 - 5p^2q^2 + 4pq - 2pq

= p^3 - 7p^2q^2 + 2pq

Therefore,

p^3 - 7p^2q^2 + 2pq should be added.

Step-by-step explanation:

There are 120 different combinations when selecting Christmas presents.

There are 10 available presents in all under a Christmas tree, and

The number of presents chosen to be placed beneath a Christmas tree is 3.

We must determine how many possible combinations there are.

There are a total of three methods by which the 10 gifts can be chosen \(10C_{3}\).

that is

\(nC_{r}=\frac{n!}{r!(n-r)!}\)

\(10C_{r} =\frac{10!}{3!(10-3)!}\)

=120

In order to choose three gifts from a total of ten, there are 120 possible different combinations.

The term "probability" is most commonly used to refer to the likelihood that a specific event (or group of events) will occur, either as a linear scale from 0 (impossibility) to 1 (certainty) or as a percentage between 0 and 100%. Statistics is the study of events subject to probability.

The simplified form of the expression \((-7a^3b^{-3})\) / (21ab) is \((-a^2) / (3b^3),\) removing negative exponents and canceling out common factors.

To simplify the given expression, let's break it down step by step.

The expression is:

\((-7a^3b^{-3}) / (21ab)\)

First, we can simplify the numerator by applying the exponent rules.

The negative exponent in the numerator can be rewritten as a positive exponent in the denominator:

\((-7a^3) / (21ab^3)\)

Next, we can simplify the fraction by canceling out common factors in the numerator and denominator. In this case, we can cancel out the common factor of 7:

\((-a^3) / (3ab^3)\)

Now, we can simplify the remaining terms by canceling out the common factor of 'a':

\((-a^2) / (3b^3)\)

Finally, we have simplified the expression to \((-a^2) / (3b^3)\).

In this simplified form, the expression no longer contains negative exponents or common factors in the numerator and denominator.

To summarize, the simplified form of the expression \((-7a^3b^{-3}) / (21ab)\) is \((-a^2) / (3b^3).\)
