Step-by-step explanation:

the maximum volume is

⅓×18³= 972 cm³

Answer:

a

  The null hypothesis is  \(H_o : p = 0.67\)

   The alternative hypothesis is  \(H_a : p \ne 0.67\)

b

 The sample proportion is \(\^ p = 0.65\)

Step-by-step explanation:

From the question we are told that

     The sample size is  n =  546  

      The number of people that use a laptop overnight is  \(k = 355\)

    The population proportion is  \(p = \frac{2}{3} = 0.67\)

   Generally

  The null hypothesis is  \(H_o : p = 0.67\)

   The alternative hypothesis is  \(H_a : p \ne 0.67\)

Gnerally the sample proportion is mathematically represented as

        \(\^ p = \frac{ k}{n}\)

=>     \(\^ p = \frac{ 355}{546}\)

=>     \(\^ p = 0.65\)

Steps to solve:

3(3x - 6) = 18

~Distribute left side

9x - 18 = 18

~Add 18 to both sides

9x = 36

~Divide 9 to both sides

x = 4

Best of Luck!

Answer:

x = 4

Step-by-step explanation:

Let's work on isolating (3x - 6).  Start by dividing both sides of 3(3x - 6) = 18 by 3, obtaining:

3x - 6 = 6.

Next, add 6 to both sides:

3x = 12

Finally, divide both sides by 3:

x = 4

Answer:

Answer is 7.

Step-by-step explanation:

(a + 2)^4- 20(a + 2)^2+ 64 = 0

2a^4- 20(2a)^2+ 64 = 0

16a-20(4a)+64=0  

-4a    -64  -4a          -64

12a-84=0

    +84 +84

12a=84

The mean of the given data is 12.4

The mean can be calculated only for numeric variables, no matter if they are discrete or continuous. It's obtained by simply dividing the sum of all values in a data set by the number of values.

Given that, a data, 10, 12, 11, 13, 14, 12, 13, 14, 13, and 12

Arranging the data in ascending order, 10, 11, 12, 12, 12, 13, 13, 13 14, 14

The sum is = 10+12+11+13+14+12+13+14+13+12 = 124

Total number of data = 10

Mean = sum of the numbers/ total numbers of data

Mean = 124/10

Mean = 12.4

Hence, the required mean is 12.4

We substitute -1+1/6y for x in the second equation (bottom equation) in order to solve the system by the substitution method.

The given system of equations are 2x-1/3y = -2...(1)

3x+y=1...(2)

We solve this system of equations by using substitution method.

Let us solve for x in equation to substitute it in equation (2).

2x=-2+1/3y

Divide both sides of equation by 2.

x=-1+1/6y

Now plug in the value of x in equation 2.

Hence, we substitute -1+1/6y for x in the second equation (bottom equation) in order to solve the system by the substitution method.

The equivalent value of the equation A = 1 + 1 = 2

Given data ,

Let the equation be represented as A

Now , the value of A is

A = one plus one

On writing the expression in numerical form , we get

A = 1 + 1

On simplifying , we get:

And , the number line representation of the equation is

The "=" sign and terms on both sides must always be present when writing an equation.

A = 1 + 1 = 2

Therefore , the value of A is 2

where the value of A can be calculated from the distributive property as

A = 2 x 1

On simplifying the expression , we get

A = 2

Therefore , the value of A = 2

Hence , the equation is A = 2

Answer:

Step-by-step explanation:

Since the question is not complete, I will be solving for probability of 3 9s

To solve this, we would be using the principle of combination, and thus

A deck of 52 hours has 4 nines, the probability that it contains at least 3 9s is mathematically represented by the equation.

P ( x ≥ 3 ) = ( 48 C 10 · 4 C 3 ) / ( 52 C 13 ) + ( 48 C 9 · 4 C 4 ) / ( 52 C 13 )

Remember I told us were going to be using the principle of combination. Well then

nCr = n!/r!(n - r)!

Now, applying the above stated formula to the equation, we have

48C10 = 48!/10!(38!)

4C3 = 4!/3!(1!)

52C13 = 52!/13!(39!)

48C9 = 48!/9!(39!)

4C4 = 4!/4!(0!)

Solving for each independently, we find that

= 0.0412 + 0.588 = 0.1

The maximum and minimum set of dimension for the rectangular field are-

A rectangle is a four-sided configuration with 90-degree angles at all four corners. A rectangle's sides are same length than the one opposite it.

The perimeter of the rectangular field is given in the form of equation;

4x + 3y = 100

Where the total area is given as;

y(x+x) = 374

2xy = 374

Solving the equation;

(4 x+3 y)² = 16x² + 12×2 x y + 9 y² = 10000

2 x y = 374,12.

2 x y = 12 × 374

2 x y = 4488

16x² + 9 y² = 10000 - 4488

16x² + 9 y² = 5512

Now, solve for the other set of value;

(4 x-3 y)² =  16x² - 12×2 x y + 9 y²

Put the value of 16x² + 9 y² = 5512.

(4 x-3 y)² =  5512 - 12×2 x y

Put 2xy = 374

(4 x-3 y)² =  5512 - 4488

(4 x-3 y)² = 1024

Case1: 4 x-3 y = √{1024}

4 x-3 y = 32

And, 4 x + 3 y = 100

Solving both;

8x = 132

x = 16.5

and y = (100 - 32)/6

y = 11.33

Case 2: 4 x - 3 y = -32

4 x + 3 y = 100

Solving both by elimination method.

x = 8.5 and y = 22

Thus, the minimum and maximum dimension for the rectangular garden are-

Maximum (x, y) = (8.50, 22)

Minimum (x, y) = (16.50, 11.33)

The domain is determined by the set of x values covered by the graph, and the range is determined by the set of y values covered by the graph.

In the given question we have to find the domain and range of a dot graph.

A function's domain and range are really the collection of all possible outputs and inputs respectively. The range includes all of the function's output values, while the domain contains all possible input data from the set of real numbers.

If the graph of a function is known or available, it is fairly simple to determine its domain and range. The domain is determined by the set of x values covered by the graph, and the range is determined by the set of y values covered by the graph.

Answer: y=3x-2

Step-by-step explanation:

3y-9x=-6

First you will need to add 9x to the other side so your equation will look like 3y=9x-6. Then you need to divide all the numbers by 3. So 3y divided by 3 and 9 divided by 3 and -6 divided by 3. Your final answer should be y=3x-2.

Answer:

This equation in slope intercept form would be y = 3x - 2

Step-by-step explanation:

The following is how to solve this equation:
3y - 9x = -6
+9x +9x
----------------------
3y = 9x - 6
divide each of the numbers by 3

So the answer is y = 3x - 2

Answer:

Step-by-step explanation:

Trigonometric ratio in option (c) tan C will not have the same value as sin A.

Trigonometric functions are defined as the periodic functions which relate an angle in a right angled triangle to the ratios of the length of two sides.

Given a right angled triangle ABC given below.

ABC angle is 90° and angle ACB is 45°.

Then angle BAC = 180° - (90° + 45°) = 45°

Since two angles are equal, it is an isosceles triangles.

So opposite sides to the equal angles are equal.

AB = BC

AC is the hypotenuse.

Sin A = Opposite side / Hypotenuse = BC / AC

(a) Cos A = Adjacent side / Hypotenuse = AB / AC = BC / AC

(b) Sin C = AB / AC = BC / AC

(c) Tan C = Opposite side / Adjacent side = AB / BC = BC / BC = 1, not equal to Sin A

(d) Cos C = BC / AC

Hence the option (c) is not equal to sin A.
