The number of ways jokes can be delivered if a man told the jokes first is; 120 ways

The six jokes are;

1. Little boy's joke about books.

2. Little girl's joke about books.

3. Teenage girl's joke about books

4. Teenage boy's joke about books.

5. Man's joke about books.

6. Woman's joke about books.

Now, we are told that the mans joke must be first.

Thus;

Number of ways to tell first joke = 1 way

Number of ways to tell second joke = 5 ways

Number of ways to tell third joke = 4 ways

Number of ways to tell fourth joke = 3 ways

Number of ways to tell fifth joke = 2 ways

Number of ways to tell sixth joke = 1 way

Thus;

Number of ways jokes can be delivered in this manner =

1 * 5 * 4 * 3 * 2 * 1 = 120 ways.

There is not sufficient evidence at the 0.02 level of significance to say that the percentage is less than 59%.

The correct option is (b)

Now, According to the question:

In this problem, we have the following hypothesis:

[tex]H_0[/tex] : μ [tex]\geq[/tex] 0.59

[tex]H_\alpha[/tex] : μ < 0.59

The null hypothesis is the prevailing claim which the study is testing, and the alternative hypothesis is what the study is trying to prove. The null hypothesis can either be rejected or not rejected by a sample study. A sample study cannot say that the claim is absolutely correct. Only a count of the whole population can do that, and that could change at any time. In this study, the null was not rejected. The study did not have enough evidence to reject the null.

Hence, There is not sufficient evidence at the 0.02 level of significance to say that the percentage is less than 59%.

The perimeter of the quadrilateral is 10 + 6√2 units.

What is a quadrilateral?

A quadrilateral is a four-sided polygon with four edges and four corners that is used in geometry. The Latin words quadri, a variation of four, and latus, meaning "side," are the source of the name.

The coordinate of the vertices of the quadrilateral are A(-5,1), B(-1,4), C(2,1), D(-2,-2).

The length of AB arm is √[(-5-(-1))² + (1 - 4)²] = √25 = 5 units

The length of BC arm is √[(-1-2)² + (4 - 1)²] = √18 = 3√2 units

The length of CD arm is √[(2-(-2))² + (1 - (-2))²] = √25 = 5 units

The length of AD arm is √[(-5- (-2))² + (1 - (-2))²] = √18 = 3√2 units

The perimeter of a quadrilateral is the sum of length of all arms.

The perimeter of the quadrilateral is

AB + BC + CD + AD

= 5 + 3√2 + 5 + 3√2

Using system of linear equations he will require 20kg of 15% copper and 30kg of 70% copper to produce an alloy of 48% in 50kg

The system of linear equations is the set of two or more linear equations involving the same variables. Here, linear equations can be defined as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables.

To solve this problem, we need to write a system of linear equations and find the equivalent amount of the metal required to make the desired amount of the alloy.

0.15x + 0.7y = 0.48(50) ..eq(i)

0.15x + 0.7y = 24 ...eq(i)

x + y = 50 ...eq(ii)

solving equation (i) and (ii)

x = 20, y = 30

He needs 20kg of 15% copper and 30kg of 70% copper to get 48% of 50kg of alloy.

The function lim x-->a [sin(x) + a₀ + a₁x + ...+ aₙxⁿ ] has lim x-->a [sin(a) + a₀ + a₁a + ...+ aₙaⁿ] as the limit of the function as x approaches a.

Generally, To evaluate the limit of a function as x approaches a certain value, we need to substitute the value of x with the limit value and see what the function evaluates to.

In this case, we have:

lim x-->a [sin(x) + a₀ + a₁x + ...+ aₙxⁿ]

Substituting x with a, we get:

lim x-->a [sin(a) + a₀ + a₁a + ...+ aₙaⁿ]

This is the limit of the function as x approaches a.

Note that the terms a₀, a₁x, etc. are constants and will not affect the limit of the function. Therefore, the limit of the function as x approaches a is simply sin(a).

we can use the equation 14+3x=8+5x to determine when they will be they same height. X I'd

The probability that thickness of coin A will exceed thickness of coin B is 0.3905

Here, we are given that the distribution of x1 is n(1, 0.0004) and the distribution of x2 is n(1.01, 0.0009), that is-

X1 ~ N (1,0.0004) and X1 ~ N(1.01,0.0009)

Now, if a coin battery is selected at random,

The probability that the thickness of coin battery a will exceed the thickness of coin battery b = P(X1 > X2 )

It can be rewritten as follows,

P(X1-X2 > 0)

Let Y = X1-X2

The Y ~ N (1-1.01, 0.0004 + 0.0009)

i.e Y ~ N (-0.01, 0.0013)

= P(Z > 0.278)

= 0.3905

Thus, the probability that thickness of coin A will exceed thickness of coin B is 0.3905

A definite integral whose limits are functions of the differential variable can be differentiated using Newton Leibniz Theorem's formula. Differentiation under the integral sign is another name for this. When limits are functions of the differential variable, the Newton Leibniz Theorem makes it simple to handle problems involving the differentiation of a definite integral.

Suppose that F(x) is a function whose derivative is f(x). Consequently, abf(x) dx = F(b) - F (a).

The Newton Leibniz Theorem can be used to determine the derivative of a definite integral when the limits of a definite integral are functions of t and the integrands are functions of x or vice versa.

For the given function the zeroes will be 0,-11/2, and 11 while the degree of the function is 5.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

T(h)=h(2h+1)²(h-11)²

The function is simplified as,

T(h)=h((2h)²+1²+2(2h)(1))(h²+121-22h)

T(h)=h[4h²+1+4h](h²+121-22h)

T(h)=(h³+121h-22h²)(h²+121-22h)

From the above function, it is observed that the degree of the given function is 5.

The zeroes of the given function are obtained as,

T(h)=h(2h+1)²(h-11)²

T(h)=0

h = 0

(2h+1)²=0

2h+1=0

h= -1/2

(h-11)²=0

Step-by-step explanation:

5x - 12 = -2  Add 12 to both sides

5x - 12 + 12 = -2 + 12

5x = 10  Divide both sides by 5

[tex]\frac{5x}{5}[/tex] = [tex]\frac{10}{5}[/tex]

x = 2

Answer:

[tex] \sf \: (a) \: 2[/tex]

Step-by-step explanation:

Given equation,

→ 5x - 12 = -2

Now the value of x will be,

→ 5x - 12 = -2

→ 5x = -2 + 12

→ 5x = 10

→ x = 10/5

→ [ x = 2 ]

Hence, the value of x is 2.

The scatter chart indicates that there is a positive relationship between profits and market capitalization. This means that as profits increase, market capitalization also tends to increase.

The covariance between two variables is a measure of how much the variables tend to change together. A positive covariance indicates that the variables are positively related, which means that as one variable increases, the other tends to increase as well. In this case, a positive covariance between profits and market capitalization indicates that the two variables are positively related.

The correlation coefficient is a measure of the strength of the relationship between two variables. A correlation coefficient of 1 indicates a perfect positive relationship, while a coefficient of -1 indicates a perfect negative relationship. A coefficient of 0 indicates that there is no relationship between the variables. In this case, the correlation coefficient of 0.8229 indicates that there is a strong positive linear relationship between profits and market capitalization.

Multiply numerator and denominator of (4 i)/(i + 3) by 3 - i:

(3 + i) (3 - i) = 3×3 + 3 (-i) + i×3 + i (-i) = 9 - 3 i + 3 i + 1 = 10:
