Answer:

10.5

Step-by-step explanation:

63,5,0,0,45,2,23,16

order from smallest to greatest

0, 0, 2, 5, 16, 23, 45, 63

median = center number

(5 + 16) / 2 =10.5

Answer: n = 4

Step-by-step explanation:

     We will first write a mathematical equation to represent the situation. Then, we will solve it.

The sum of n → Sum means addition, so "n +"

product of 5 times n → Product and times means multiplication, so "5n"

is 24 → Is represents equals, so "= 24"

     The sum of N and the product 5 times n is 24 → n + 5n = 24

Now that we have our equation, we can solve. We will do this by adding n and 5n, then dividing both sides of the equation by 6.

     n + 5n = 24

     6n = 24

     n = 4

Answer:

A sample of 153 is needed.

Step-by-step explanation:

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 - 0.9}{2} = 0.05[/tex]

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

That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.645.

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.

Standard deviation is 15 for the population of all adults.

This means that [tex]\sigma = 15[/tex]

We wish to find the sample size necessary to estimate the mean IQ score of statistics students. Suppose we want to be 90% confident that our sample mean is within 2 IQ points of the true mean.

This means that a sample of n is needed.

n is found when M = 2. So

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

[tex]2 = 1.645\frac{15}{\sqrt{n}}[/tex]

[tex]2\sqrt{n} = 1.645*15[/tex]

Simplifying both sides by 2

[tex]\sqrt{n} = 1.645*7.5[/tex]

[tex](\sqrt{n})^2 = (1.645*7.5)^2[/tex]

[tex]n = 152.2[/tex]

Rounding up:

A sample of 153 is needed.

Step-by-step explanation:

The quotient of the division of 145413 by 321 is 453.

Division is one of the operation in mathematics where number is divideD into equal parts as that of a definite number.

We are using long division method here.

For that dividend is 145413 and divisor is 321.

First take the first some digits of dividend which is greater than 321.

That is the first four digits, 1454.

The multiple of 321 closest to 1454 is 1284 which is equal to 4 × 321

So the first digit of quotient is 4.

1454 - 1284 = 170

Now 170 is less than 321.

Add the next digit of the dividend to 170.

It becomes 1701.

Multiple of 321 closest to 1701 is 1605 which is equal to 5 × 321.

The next digit of the quotient is 5.

1701 - 1605 = 96

Again since 96 less than 321, take the next digit of the dividend and the number becomes 963.

Now 963 is a multiple of 321, where 963 = 3 × 321

So the next digit of the  quotient is 3.

Quotient = 453

Hence the quotient of the given division is 453.

Answer:

a) True

     [tex]\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha =0[/tex]

Step-by-step explanation:

Step(i):-

Given that the definite integration

           [tex]\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha[/tex]

we know that the trigonometric formula

sin²∝+cos²∝ = 1

           cos²∝ = 1-sin²∝

step(ii):-

Now the  integration

        [tex]\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha = \int\limits^\pi _0 {(\sqrt{cos^{2} \alpha } } \, )d\alpha[/tex]

                                     = [tex]\int\limits^\pi _0 {cos\alpha } \, dx[/tex]

Now, Integrating

                                 [tex]= ( sin\alpha )_{0} ^{\pi }[/tex]

                               = sin π - sin 0

                              = 0-0

                             = 0

Final answer:-

     [tex]\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha =0[/tex]

Answer:

$1400

Step-by-step explanation:

Answer:

$1,400.00

Step-by-step explanation:

You have to multiply $8.75 by the 20 hours to get $175, then you multiply that by 8 weeks to get $1,400

Answer:

B. 658 Hours

Step-by-step explanation:

All you do is divide.

$19 for every hour, it's 2 persons so,

$38 for every hour.

so,

25,000/38

= 657.894736842 which is about 658 so,

= 658 Hours

It would take 658 hours for the robot to pay for itself in labor savings

An equation is an expression that shows the relationship between two or more numbers and variables.

The robot can replace two people doing assembly work that are paid $19 per hour.

Let us assume it would take x hours for the robot to pay for itself in labor savings

(19 + 19)x = 25000

38x = 25000

x = 657.9

It would take 658 hours for the robot to pay for itself in labor savings

Answer:

$1439.16

Step-by-step explanation:

1.) 15% of 1575

1575 x 0.15 = 236.25

1575 - 236.25 = 1338.75

So 15% of $1575 = $1338.75

2.) $1338.75 with sales tax if 7.5%

1338.75 x 0.075 = 100.40625 rounded to the nearest hundredths place is 100.41

1338.75 + 100.41 = 1439.16
