Answer:

The surface area of the pyramid is 0.6625 inches²

Step-by-step explanation:

* Lets explain how to find the surface area of the square pyramid

- The square pyramid has 5 faces

- A square base

- Four triangular faces

- Its surface area is the sum of the areas of the five faces

- Area of the square = L × L , where L is the length of its sides

- Area of the triangle = 1/2 × b × h , where b is the length of its base

 and h is the length of its height

∵ The length of the side of the square is 0.25 inches

∴ Area of the base = 0.25 × 0.25 = 0.0625 inches²

∵ The length of the base of the triangle is 0.25 inches and the length

  of its height is 1.2 inches

∴ The area of its triangular face = 1/2 × 0.25 × 1.2 = 0.15 inches²

∵ The surface area of the pyramid = the sum of the areas of the 5 faces

∵ The area of the four triangular faces are equal

∴ The surface area = 0.0625 + (4 × 0.15) = 0.0625 + 0.6

∴ The surface area = 0.6625 inches²

* The surface area of the pyramid is 0.6625 inches²

Answer:

x=4/7

Step-by-step explanation:

6 - 2/3(x+5) = 4x

First I want to clear the fraction so I will multiply everything by 3

3*6 -3* 2/3(x+5) = 3*4x

18 - 2(x+5) =12x

Distribute

18 - 2x-10 =12x

Combine like terms

8 -2x = 12x

Add 2x to each side

8 -2x+2x =12x+2x

8 = 14x

Divide each side by 14

8/14 =14x/14

8/14=x

Divide top and bottom by 2

4/7=x

Answer:

Jagdish is 27 years old

Step-by-step explanation:

Jagdish=x

Resham=x+3

Rajesh=x+5

(x+3)(x+5) = 960

x²+8x+15=960

x²+8x=945

x²+8x-945=0

now factor this to solve

(x-27)=0 (x+35)=0

which means

x=27 and x=-35

obviously, we cannot have negative ages so we use x=27

so, Jagdish=27

Resham=30

Rajesh=32

and we can check this by doing 30x32 which does equal 960 so it is correct

The age of Jagdish for the condition is 27 years.

The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations. The quadratic equation has the following generic form:

ax² + bx + c = 0

Given Jagdish is 3 years younger than Resham

and  Rajesh is 5 years older than Jagdish

let age of Jagdish be x

Resham = x + 3

Rajesh = x + 5

according to conditions,

(x + 3)(x + 5) = 960

x² + 8x + 15 = 960

x² + 8x = 945

x² + 8x- 945=0

now factor this to solve

(x - 27)(x + 35) = 0

(x - 27) = 0, (x + 35) = 0

which means

x=27 and x=-35

obviously, we cannot have negative ages so we use x = 27

Therefore, the age of Jagdish is 27 years.

Answer:

14

Step-by-step explanation:

Assuming the die is 6 sided, there are only 6 possible rolls she can get. And assuming that this is a perfect world where probability is perfect, she will roll each number 14 times, because 84/6 is 14.

Final answer:

Kayla can expect to roll a number 3 approximately 14 times out of 84 rolls of a fair six-sided die, since each roll has a 1 in 6 chance of landing on any given number.

Explanation:

When Kayla rolls a die 84 times, she can expect to roll a 3 in a proportion equal to the probability of rolling a 3 on a single die. A fair six-sided die has a 1 in 6 chance of landing on any given number, including the number 3. Since each roll of the die is independent, we can calculate the expected frequency of rolling a 3 by multiplying the total number of rolls by the probability of rolling a 3.

The calculation is straightforward:

Therefore, Kayla can expect to roll a 3 approximately 14 times in 84 rolls.

The given equation is:

[tex] {x}^{ - 2} + 4 {x}^{ - 1} + 3 = 0[/tex]

Recall that:

[tex] {a}^{ - m} = \frac{1}{ {a}^{m} } [/tex]

[tex] \frac{1}{ {x}^{2} } + \frac{4}{x} + 3 = 0[/tex]

Or

[tex] {( \frac{1}{x} )}^{2} + 4( \frac{1}{x} ) + 3 = 0[/tex]

Let

[tex]u = \frac{1}{x} [/tex]

Our equation then becomes:

Answer:

D

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ 2, 4 ]

From the table

f(b) = f(4) = 16

f(a) = f(2) = 4, hence

average rate of change = [tex]\frac{16-4}{4-2}[/tex] = [tex]\frac{12}{2}[/tex] = 6

The average rate of change for a function is calculated using the change in y-values divided by the change in x-values.

The average rate of change for a function is the change in the y-values (output) divided by the change in the x-values (input) over a given interval. To calculate the average rate of change for the function from x = 2 to x = 4, we need to find the change in y-values and the change in x-values for this interval.

Let's assume the function is f(x). We can calculate the average rate of change using the formula:

Average Rate of Change = (f(4) - f(2)) / (4 - 2)

Replace f(4) and f(2) with the corresponding y-values for x = 4 and x = 2, respectively, to get the final result.

Step-by-step explanation:

Let's call "v" the speed of the commercial airplane and call "t" at the travel time of the commercial plane

The distance in kilometers of the trip is: 1730 km

Then we know that:

[tex]vt=1730[/tex]

Then for the jet we have that the speed is:

[tex]2v[/tex]

The flight time for the jet is:

Answer:

Step-by-step explanation:

The number of grains of wheat on the n(th) square is 2^(n-1), or 2 to  

the power of n-1.  This is because the first square has 2^0 = 1 grain,  

the second has 2^1 = 2, and the n(th) square has twice as many as the  

previous. Thus the total number of grains of wheat is

    S = 1 + 2 + 4 + 8 + ... + 2^63.

Since this is a geometric sequence with common ratio 2, the sum is

        2^64 - 1

    S = -------- = 2^64 - 1 = 18446744073709551615.

Mode: 3 because it appears the most

Answer:

A. Mean = $41900

B. Median = $37000

C. Mode = $37000

Step-by-step explanation:

A. Mean

Here

n=40

Mean = Sum of values/n

[tex]Mean = \frac{(3)(18000)+(3)(22000)+(3)(25000)+(5)(34000)+(17)(37000)+(2)(45000)+52000+(5)(80000)+140000}{40}\\=\frac{54000+66000+75000+170000+629000+90000+52000+400000+140000}{40} \\=\frac{1676000}{40}\\=41900[/tex]

Mean = $41900

B. Median:

As the number of salaries is even,

the median will be mean of middle two terms

[tex]Median= \frac{1}{2}(\frac{n}{2}th\ term+ \frac{n+2}{2}th\ term)\\=  \frac{1}{2}(\frac{40}{2}th\ term+ \frac{40+2}{2}th\ term)\\=\frac{1}{2} (20th + 21st)}\\[/tex]

The 20th and 21st term will be 37000

So their mean will be same

So,

Median = $37000

C. Mode

Mode is the value which occurs most of the time in data.

the occurrence of 37000 is highest in the given data.

So,

Use foil.

First: i(i)=i^2=-1

Outer: i(7)=7i

Inner: 7(i)=7i

Last: 7(7)=49

____________Add the terms.

48+14i

After solving the expression, the result of squaring value of a will be equal to 14i + 48.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the data provided by the question,

i² = -1

a = (i + 7)

Squaring the value of a,

a = (i + 7)(i + 7)

a = i² + 7i + 7i +49

a = -1 + 14i + 49

a = 14i +48

Step-by-step answer:

The coefficients of terms of (p+q)^n can be found by the Pascal's triangle for small values of n.  Pascal's triangle will start with (1,1)  = coefficients of (p,q)^n =1.  For n=2, we add successive terms of the previous value of n.  Thus for n-2, we have (, 1+1,11=(1,2,1), for n=3, we have (1,3,3,1), giving the following pattern:

(1,1)

(1,2,1)

(1,3,3,1)

(1,4,6,4,1)

(1,5,10,10,5,1)

meaning for n=5, the binomial expansion for (P+Q)^5 is

P^5+5P^4Q+10P^3Q^2+10P^2Q^3+5PQ^4+Q^5

Setting P=2x, Q=y in the term 10P^3Q^2, we get a term

10(2x)^3(y)^2

=10(8x^3)(y^2)

=80x^3y^2

So the required coefficient is K=80.

We can also find the coefficient 10 by binomial expansion of

n=5, x=3 in

C(n,x) = n! / (x! (n-x)!) = 5! / (2!3!) = 5*4*3/(1*2*3) = 10

Answer:

Step-by-step explanation:

Direction variation is of the form y = kx.

This is not direct variation.

The equation 3y = 5x + 4 does not represent a direct variation because it includes a constant term '+4'. A direct variation would only have the form y = kx without any added or subtracted constants.

The equation 3y=5x+4 represents a direct variation, and if so, to find the constant of variation. A direct variation is when one variable is a constant multiple of another, expressed in the form y = kx, where k is the constant of variation. In this case, the equation 3y = 5x + 4 is not a direct variation because of the additional constant term '+4'. For it to be a direct variation, y must be alone on one side of the equation, and there should be no constant term added or subtracted with the term that is a multiple of x.

To be a direct variation, the equation needs to have the form y = kx. In the practice equation y + 7 = 3x, if we solve for y, we get y = 3x - 7 which still would not be a direct variation because of the -7. The other example equation 4y = 8 is not in the form of direct variation either since it has no variable x in it; it represents a horizontal line where y is a constant.

Final answer:

The five number summary for the ages of best actress Oscar winners is composed of the minimum (21), first quartile (Q1 - 30), median (Q2 - 33), third quartile (Q3 - 41), and maximum (81) values.

Explanation:

The first step to finding the five number summary is to identify the minimum, first quartile (Q1), median (second quartile Q2), third quartile (Q3), and the maximum from the sorted dataset of best actress Oscar winners.

Minimum: The smallest number in the dataset is 21.

Q1: The first quartile is the median of the first half of the data. Since we have an odd number of data points (91), we split the data into two parts of 45 values each. The first quartile is the median of the first 45 ages, which is the 23rd data point in the sorted list when counting from the smallest age. In our case, Q1 is 30.

Median (Q2): The median is the middle value, which is the 46th data point for our 91 data points. The median is also the age of 33.

Q3: The third quartile is the median of the second half of the data. The third quartile is the 68th data point, which is the age of 41.

Maximum: The largest age in the dataset is 81.

Therefore, the five number summary of the ages of best actress Oscar winners is 21, 30, 33, 41, and 81.

Answer:

second option

Step-by-step explanation:

We are going to use the acronym:

"Soh Cah Toa".

Why? It tells us the right-triangle definitions of sine, cosine, and tangent.

sine is opposite over hypotenuse.

cosine is adjacent over hypotenuse.

tangent is opposite over adjacent.

So looking at our triangle with respect to B tells us that 3 is the opposite measurement and 6 is the adjacent.  No matter what angle we are looking for in this triangle, the hypotenuse is constantly going to by [tex]3\sqrt{5}[/tex].

So let's look at cos(B).

[tex]\cos(B)=\frac{6}{3\sqrt{5}}[/tex]

We need to rationalize the denominator by multiplying top and bottom by sqrt(5):

[tex]\cos(B)=\frac{6\sqrt{5}}{3(5)}=\frac{2\sqrt{5}}{5}[/tex]

So now looking at sin(B).

[tex]\sin(B)=\frac{3}{3\sqrt{5}}[/tex]

We have to rationalize again by multiplying top and bottom by sqrt(5):

[tex]\sin(B)=\frac{3\sqrt{5}}{3(5)}=\frac{\sqrt{5}}{5}[/tex].

So looking at our triangle with respect to A tells us that 3 is the adjacent measurement and 6 is the opposite.  No matter what angle we are looking for in this triangle, the hypotenuse is constantly going to by [tex]3\sqrt{5}[/tex].

We don't have to use any trigonometric ratios with A.
