Answer:

[tex]r = 35cm[/tex]

Step-by-step explanation:

Given

[tex]C = 220cm[/tex]

[tex]\pi = \frac{22}{7}[/tex]

Required

Determine the radius

Circumference (C) is calculated as:

[tex]C = 2\pi r[/tex]

Where r represents radius

Substitute values for C and [tex]\pi[/tex]

[tex]220cm = 2 * \frac{22}{7} * r[/tex]

[tex]220cm = \frac{44}{7} * r[/tex]

Multiply through by 7/44

[tex]\frac{7}{44} * 220cm = \frac{7}{44} * \frac{44}{7} * r[/tex]

[tex]r = \frac{7}{44} * 220cm =[/tex]

[tex]r = \frac{7 * 220cm }{44} =[/tex]

[tex]r = \frac{1540\ cm}{44}[/tex]

[tex]r = 35cm[/tex]

Hence, the radius is 35cm

Answer:

50 + 25 + (8*5) - (7 + 4)

Step-by-step explanation:

50 + 25 + (8*5) - 7 + 4 = 50 + 25 + 40 -  7  + 4

                                      = 115 - 7 + 4

                                      = 108 + 4

    The decision rule is  

Fail to reject the null hypothesis

Step-by-step explanation:

From the question we are told that

  The value given is  

S/N

1       7 5

2      4 3

3      8 7

4      8 8

5      7 9

6      7 5

7      6 5

Generally the sample mean for the first sample  is  mathematically represented as

        [tex]\= x _1 = \frac{\sum x_i }{n}[/tex]

=>     [tex]\= x _1 = \frac{7 +4 + \cdots + 6}{7}[/tex]

=>     [tex]\= x _1 = 6.714[/tex]

Generally the sample mean for the second sample is mathematically represented as

        [tex]\= x _2 = \frac{\sum x_i }{n}[/tex]

=>     [tex]\= x _2 = \frac{5 + 3+ \cdots + 5}{7}[/tex]

=>     [tex]\= x _2 = 6[/tex]

Generally the sample standard deviation  for the first sample  is  mathematically represented as

           [tex]s_1 = \sqrt{\frac{\sum (x_i - \= x_1)^2 }{n-1 } }[/tex]

=>       [tex]s_1 = \sqrt{\frac{ (7 - 6.714 )^2 +(4 - 6.714 )^2 + \cdots + (6 - 6.714 )^2 }{7-1 } }[/tex]

=>       [tex]s_1 = 1.905[/tex]

Generally the sample standard deviation  for the second  sample  is  mathematically represented as

           [tex]s_2 = \sqrt{\frac{\sum (x_i - \= x_2)^2 }{n-1 } }[/tex]

=>       [tex]s_2 = \sqrt{\frac{ (5 - 6.714 )^2 +(3 - 6.714 )^2 + \cdots + (5 - 6.714 )^2 }{7-1 } }[/tex]

=>       [tex]s_1 = 4.33[/tex]

Generally the pooled standard deviation is  

      [tex]s = \sqrt{\frac{(n_1 - 1 )s_1^2 + (n_2 - 1 )s_2^2}{n_1 + n_2 -2 } }[/tex]

=>    [tex]s = \sqrt{\frac{(7 - 1 )1.905^2 + (7 - 1 )4.333^2}{7 + 7 -2 } }[/tex]

=>    [tex]s = 1.766[/tex]

The null hypothesis is  [tex]H_o : \mu_1 = \mu_2[/tex]

The alternative hypothesis  [tex]H_a : \mu_1 > \mu_2[/tex]

Generally the test statistics is mathematically represented as

      [tex]t = \frac{\= x _1 - \= x_2 }{s * \sqrt{\frac{1}{n_1} + \frac{1}{n_2}} }[/tex]

=>   [tex]t = \frac{6.714 - 6 }{1.766 * \sqrt{\frac{1}{7} + \frac{1}{7}} }[/tex]

=>   [tex]t = 0.757[/tex]

Generally the degree of freedom is mathematically represented as

     [tex]df = n_1 + n_2 - 2[/tex]

=>   [tex]df = 7 + 7 - 2[/tex]

=>   [tex]df = 12[/tex]

From the t distribution table the probability of  [tex]t = 0.757[/tex] at a degree of freedom of [tex]df = 12[/tex] is  

     [tex]t_{ 0.757 , 12} = 0.232[/tex]

Generally the p-value is  

      [tex]p-value = t_{ 0.757 , 12} = 0.232[/tex]

From the values  obtained we see that [tex]p-value > \alpha[/tex]  hence  

   The decision rule is

Using the normal distribution, it is found that 66.9% of filled boxes of rice have a weight between 28 and 29 ounces.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given, respectively, by: [tex]\mu = 28.2, \sigma = 0.4[/tex].

The proportion of filled boxes of rice have a weight between 28 and 29 ounces is the p-value of Z when X = 29 subtracted by the p-value of Z when X = 28, hence:

X = 29:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{29 - 28.2}{0.4}[/tex]

Z = 2

Z = 2 has a p-value of 0.977.

X = 28:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{28 - 28.2}{0.4}[/tex]

Z = -0.5

Z = -0.5 has a p-value of 0.308.

0.977 - 0.308 = 0.669 = 66.9%.

Answer:

Substitution property of equality

Step-by-step explanation:

Given

[tex]3x + 4y = 6[/tex]

[tex]x = 5[/tex]

[tex]3(5) + 4y = 6[/tex]

Required

Name the property used

From the question, we have that: [tex]x = 5[/tex]

This implies that 5 can be substituted for x in the given equation [tex]3x + 4y = 6[/tex]

So, when 5 is substituted for x, we have that:

[tex]3(5) + 4y = 6[/tex]

Conclusively, the property that was applies is the Substitution property of equality

Answer:

39.30 [tex]cm^{2}[/tex]

Step-by-step explanation:

The area of the top surface of the wedge is the same as the area of a sector.

Area of a sector = (θ/[tex]360^{o}[/tex])[tex]\pi[/tex][tex]r^{2}[/tex]

where: θ is the central angle, and r is the radius.

Given that: central angle = [tex]45^{o}[/tex], radius = 10 centimetre.

Area of the top surface = Area of a sector = (θ/[tex]360^{o}[/tex])[tex]\pi[/tex][tex]r^{2}[/tex]

                                      = [tex]\frac{45^{o} }{360^{o} }[/tex] x [tex]\frac{22}{7}[/tex] x [tex](10)^{2}[/tex]

                                      = [tex]\frac{1}{8}[/tex] x [tex]\frac{22}{7}[/tex] x 100

                                      = 39.2857

                                     = 39.30 [tex]cm^{2}[/tex]

The area of the top surface of the wedge is 39.30 [tex]cm^{2}[/tex].

The area of the top surface of wedge shaped cheeses bought by Mai is 39.3 cm².

The area of a circular sector is the total space occupied by it. The sector area is half of the product of the square of radius of the circle and the central angle.

It can be calculated if theta is measure in radian as,

[tex]A_{sector}=\dfrac{r^2\theta}{2}[/tex]

It can be calculated if theta is measure in degrees as,

[tex]A_{sector}=\dfrac{\pi r^2\theta}{360}[/tex]

Here, (r) is the radius of the circle and (θ) is the central angle.

Several different cheeses are for sale. The cheese comes in wedges shaped like sectors of a circle. All of the wedges are the same height.

Mai bought a wedge with a central angle of 45 degrees and radius 10 centimeters. Thus, the area of the top surface of this wedge is,

[tex]A_{sector}=\dfrac{\pi (10)^2(45)}{360}\\A_{sector}\approx 39.3\rm\; cm^2[/tex]

Thus, the area of the top surface of wedge shaped cheeses bought by Mai is 39.3 cm².

Step-by-step explanation:

Did the quiz

Let the amount Nick gets = x

Angad gets 3x ( 3 times as much as Nick)

Peter gets 6x (Twice as much as Angad)

Add together to equal the total amount:

x + 3x + 6x = 200

Simplify:

10x = 200

Divide both sides by 10:

x = 20

Angad gets 3x = 3(20) = 60
