Vlada [557]3 years ago

Answer:

5981.25 m²

Step-by-step explanation:

1. Divide the court into two sections. One section being the semicircle, the other being the rectangle.

2. Multiply 100 by 50 to get the area of the rectangle, which is 5000.

3. Divide 50 by 2 to get the radius of the semicircle, which is 25.

4. Find the formula used for area of a semicircle A = \frac{1}{2}\pir²

5. Insert 25 into where the "r" is in the equation: A = \frac{1}{2}\pi(25²), resulting in about 981.25. (I replaced \pi with 3.14)

6. Add the area of the rectangle with the area of the semicircle, 5000 + 981.25 = 5981.25.

7. The final answer is 5981.25 m².

Answer:

The  confidence interval is  64.86

Step-by-step explanation:

From the question we are given the following data

   The following heights are

66, 65, 67, 62, 62, 65, 61, 70, 66, 66, 71, 63, 69, 65, 71, 66, 66, 69, 68, 62, 65, 67, 65, 71, 65, 70, 62, 62, 63, 64, 67, 67      

 The  sample size is n  =32

  The confidence level is k  = 95% = 0.95

The mean is evaluated as

          \= x = 66+ 65+ 67+ 62+ 62+ 65+ 61+ 70+ 66+ 66+ 71+63+ 69+ 65+ 71+ 66+ 66+ 69+ 68+ 62+ 65+ 67,+\\65+ 71+ 65+ 70+ 62+ 62+ 63+ 64+ 67+ 67 / 32

=>   \= x = \frac{2108}{32}

=>     \= x = 65.875

The standard deviation is evaluated as

           \sigma =  \sqrt{ v}

Now  

   v = ( 66-65.875 )^2+(65-65.875)^2+( 67-65.875)^2+ (62-65.875)^2+ (62-65.875)^2+ (65-65.875)^2+( 61-65.875)^2+ (70-65.875)^2+ (66-65.875)^2+ (66-65.875)^2+ (71+63-65.875)^2+ (69-65.875)^2+ (65-65.875)^2+ (71-65.875)^2+( 66-65.875)^2+ (66-65.875)^2+ (69-65.875)^2+ (68-65.875)^2+ (62-65.875)^2+ (65-65.875)^2+ (67-65.875)^2,+\\(65-65.875)^2+ (71-65.875)^2+ (65-65.875)^2+ (70-65.875)^2+( 62-65.875)^2+( 62-65.875)^2+ (63-65.875)^2+ (64-65.875)^2+ (67-65.875)^2+ (67-65.875)^2 / 32

=>v=  8.567329

=>   \sigma  =  \sqrt{8.567329}

=>   \sigma  =  2.927

The level of significance is evaluated as

        \alpha  =  1 - 0.95

        \alpha  =  0.05

The degree of freedom is  evaluated as

    Df =  n- 1 \equiv  Df  =  32 -1 = 31

The critical values for the level of significance is obtained from the z -table as

      t_c = t_{\alpha/2 } , Df =  t _{0.05/2}, 31 =\pm 1.96

The confidence interval is evaluated as

       \mu  = \= x \pm t_c *  \frac{\sigma }{\sqrt{n} }

substituting values

        \mu =65.875 \pm 1.96* \frac{2.927}{\sqrt{32} }

       \mu =65.875 \pm 1.01415

=>    64.86

A container has 20 12 cups of pancake mix. A serving uses exactly 2 ) cups.
just olya [345]

Answer:

10 full servings and \frac{1}{4} cups leftover

Step-by-step explanation:

Our container has a total of 20 and a half cups. And each full serving is 2 cups.

So, we divide \frac{20\frac{1}{2} }{2}.

To do this manually, we convert the numerator into an improper fraction: \frac{\frac{41}{2} }{2}.

Now, we multiply the denominators: \frac{41}{4}.

This will give us 10\frac{1}{4} servings. So we only have 10 full servings.

There are \frac{1}{4} cups leftover.
