Answer:

$0.71

Step-by-step explanation:

9.99 + (3% of 9.99) = 10.2897

11 - 10.2897 = 0.7103, so $0.7103 is our answer. However, this isn't a real amount of money that can be handed from a clerk to a customer. So, we will round it to the nearest cent, bringing us to $0.71, our final answer.

Step-by-step explanation:

Answer:

121 degrees

Step-by-step explanation:

Given

Radius r = 18ft

Length of the arc = 38ft

Required

angle of rotation

Using the formula

Length of an arc = theta/360 * 2πr

Substitute the given data

38 = theta/360 * 2π(18)

38 = theta/360 * 113.04

theta/360 = 38/113.04

theta/360 = 0.33616

theta = 0.33616 * 360

theta = 121.02

Hence the angle of rotation to the nearest degree is 121 degrees

Answer:

The sample mean year is 1261 A.D.

The standard standard deviation is of 46 A.D.

Step-by-step explanation:

Sample mean:

Sum of all values divided by the number of values. So

[tex]x = \frac{1271+1187+1194+1250+1268+1316+1275+1317+1275}{9} = 1261.4[/tex]

Rounding to the nearest whole number, the sample mean year is 1261 A.D.

Sample standard deviation:

Square root of the sum of the difference squared between each value and the mean, divided by one less than the sample size. So

[tex]s = \sqrt{\frac{(1271-1261.4)^2+(1187-1261.4)^2+(1194-1261.4)^2+(1250-1261.4)^2+(1268-1261.4)^2+(1316-1261.4)^2+(1275-1261.4)^2+(1317-1261.4)^2+(1275-1261.4)^2}{8}} = 45.8[/tex]

Rounding to the nearest whole number, the standard standard deviation year is of 46 A.D.

Answer:

Sin 2 (30)°=  [tex]\frac{\sqrt{3} }{2}[/tex]

Step-by-step explanation:

Explanation:-

Given that   Sin 2 (30)°

we know that the formula  sin2θ = 2sinθ cosθ

   Given that θ = 30°

   Now  

         sin2(30)° = 2sin30° cos30°

                                             [tex]= 2 ( \frac{1}{2} X \frac{\sqrt{3} }{2} )[/tex]

       After cancellation, we get

                           Sin 2 (30)° = [tex]\frac{\sqrt{3} }{2}[/tex]

Final answer:-

          Sin 2 (30)° = [tex]\frac{\sqrt{3} }{2}[/tex]

Answer:

5.66

Step-by-step explanation:

This is a 45 – 45 – 90 triangle. What this means is that the two legs are both congruent and the hypotenuse is the length of the legs times [tex]\sqrt{2}[/tex].

So in order to find this, we have to divide 8 by the square root of 2.

Putting this in to a calculator, we get 5.6568542. When rounded to the nearest hundredth, it is 5.66, which is the first answer.

Answer:

8904 People

Step-by-step explanation:

We start by the equation L = 12E, where L represents the population of Linton and E represents the population of Ellmore. We then set L + E = 9646, but since L = 12E, we then get 12E + E = 9636, or 13E = 9646. Therefore, E = 742. L = 12E, so L = 8904.

Answer:

1/35

Step-by-step explanation:

P= 6 *13! / 15! = 1/35

The probability of two east high school swimmers to come first and second is 1/35.

How to calculate probability?

First, let us calculate the number of desired outcomes:

The first position has 3 possibilities and 2nd position has 2 possibilities and 3rd position has 13 possibilities (leaving people of 1st and 2nd position).

Total=2.3.13

Now, calculate the total outcome:

1st position has 15 possibilities, 2nd has 14 and 3rd has 13.

Total=15.14.13

Probability=desired outcome/total outcome

                 =2.3.13/15.14.13

                 =1/35

Therefore, probability of the given situation is 1/35.
