Answer: try -2

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

If we use PEMDAS, we know that we need to do the multiplication and division first. (1/2)^4 is equal to 1^4/2^4, which is 1/16. Next, 1/16 * 32 is equal to 2. Finally, we do 6 divided by 3, which is 2. 2 - 2 is equal to 0, so the answer is 0.

Answer:

option d 11 .......substitute 2 inplace of x

Step-by-step explanation:

a^2 + b^2 = c^2

a = 6

b = x

c = 11

6^2 + b^2 = 11^2

36 + b^2 = 121

b^2 = 121 - 36

b^2 = 85

Find the square root of both sides.

b = 9.22

Answer:

a) 2/3

b) 1/9

c) 52/99

d) 2/11

e) 743/999

f) 29/111

Step-by-step explanation:

Take the recurring numbers (numbers after the decimal). If there is one recurring number place it over 9, if there are two then place them over 99, if there are three then place them over 999 etc.

Then simplify (if possible).

a) 6/9 = 2/3

b) 1/9

c) 52/99

d) 18/99=2/11

e) 743/999

f) 261/999=29/111

The factors of given quadratic equation

  [tex]x = \frac{9}{15} and x = -2[/tex]

Step-by-step explanation:

Explanation:-

Given quadratic equation 15x² +39 x -18 =0

The factors of 270 = 30 × 9

The quadratic equation 15x² +39 x -18 =0

                                   ⇒ 15 x² +30 x-9x -18=0

                                ⇒ 15x(x+2) -9( x+2) =0

                               ⇒( 15x -9)(x+2) = 0

                      15x - 9=0    and  x+2 =0

                      15 x =9   and  x = -2

                      [tex]x = \frac{9}{15} and x = -2[/tex]

Answer:

Step-by-step explanation:

2880° per ride doesn't make sense, because it is not a whole number.

Do you mean 2880° per ride?

r = 8 feet

circumference = 2πr = 16π feet

2880° × (16π feet)/(360°) = 128π feet ≅ 402 feet

A rider seated 8 feet from the merry-go-center round would travel 392.2 feet during the ride.

The circumference is the distance that surrounds a circle. We can measure the circumference of the earth by measuring the distance that we will have to walk all the way around the world.

Given, A merry go round rotates 2808 degrees per ride. A rider is seated 8 feet from the center.

Thus r = 8 feet

Circumference = 2πr

Circumference = 2π*8

Circumference = 16π

Distance traveled by that man = 2808* 16π/360

Distance traveled by that man = 392.22 feet

therefore, a rider seated 8 feet from the center of the merry-go travel during the ride would travel 392.2 feet.

Answer:

the amount received from the credit card company is $19.16

Step-by-step explanation:

The computation of the amount received from the credit card company is shown below:

= Purchase made by the customer × received percentage

= $20 × 95.8%

= $19.16

Hence, the amount received from the credit card company is $19.16

Answer:

discrete, the class boundaries are;

16 - 25

26 - 35

36 - 45

46 - 55

56 - 65

66 = 75

continuous, the class boundaries are;

16 to less than 26

26 to less than 36

36 to less than 46

46 to less than 56

56 to less than 66

66 to less than 76

Step-by-step explanation:

Given that;

Range of the dataset = maximum value - minimum value = 74 - 16 = 58

total number of data set n = 50

Rule : [tex]2^{k}[/tex] ≥ n

substitute value of n

[tex]2^{k}[/tex] ≥ 50

k × log(2) = log( 50 )

k × 0.3010 = 1.69897

k = 1.69897 / 0.3010

k = 5.64

Hence, we have a total of 6 number of classes needed to be constructed.

so,

class width = 74 - 16 / 6 = 58 / 6 = 9.67

If the Data is discrete, the class boundaries are;

16 - 25

26 - 35

36 - 45

46 - 55

56 - 65

66 = 75

If the Data is continuous, the class boundaries are;

16 to less than 26

26 to less than 36

36 to less than 46

46 to less than 56

56 to less than 66

66 to less than 76

The game is formed such that a duck is either winning duck or a non winning duck .

there is no other result for any duck present in the game .

Also choosing a duck is a fair game it is independent of any prior situation .

here we would be using a basic probability formula , that is

Probability of a result = number of items in favour of that result divide by total number of items present in the game .

Answer: C (x=1)

Step-by-step explanation:

f(x)=0 at points of intersection of the graph of the function with x-axis.

The graph of the function intersects x-axis at three points:

somewhere between -3 and -2;

somewhere between -1 and 0;

at x=1.

Since x=1 is the value of x from the domain, then correct choice is option C.

Answer:

a) The margin of error associated with a 95% confidence interval is of $4.73.

b) $26.49 to $35.95

Step-by-step explanation:

Question a:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]

Now, find the margin of error M as such

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.96*\frac{19}{\sqrt{62}} = 4.73[/tex]

The margin of error associated with a 95% confidence interval is of $4.73.

Question b:

The lower end of the interval is the sample mean subtracted by M. So it is 31.22 - 4.73 = $26.49

The upper end of the interval is the sample mean added to M. So it is 31.22 + 4.73 = $35.95

So $26.49 to $35.95

D. Move the decimal point in 132.9 three places to the left.

Step-by-step explanation:

Multiplication of a decimal by the nth power of 10:

We move the decimal point n places to the right.

Division of a decimal by the nth power of 10:

We move the decimal point n places to the left.

In this question:

There is a division by 1000, which is the 3rd power of 10, because [tex]10^3 = 1000[/tex]

So, we should move the decimal point three places to the left, and the correct answer is given by option D.
