Answer:

Simple random sampling survey method

Step-by-step explanation:

A simple random sampling is an unbiased survey technique Hence it will represent all the parts of the city's population.

In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process

Answer:

hope i helped :)

Step-by-step explanation:

some survey methods that could produce a representative sample of the city's population could be as follows:

o panel sampling

o online surveys

o mail-in surveys

Answer:

Yes

Answer:

z-method: (66.26, 75.18)

Step-by-step explanation:

We have the standard deviation for the population, which means that we use the z-distribution to solve this question.

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].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

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{16.25}{\sqrt{51}} = 4.46[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 70.72 - 4.46 = 66.26

The upper end of the interval is the sample mean added to M. So it is 70.72 + 4.46 = 75.18

The correct answer is z-method: (66.26, 75.18)

I remember it by:

acute: a cute little angle that is smaller than 90 degrees

Answer:

cos(33) = 6/X

cos(33)*6= X

X= 5.03202340767254

rounded to the nearest tenth it is 5

therefore X= 5

The value of x in the given digram using trigonometry to the nearest tenth is 7.15.

The given image is a right triangle. A right triangle is a triangle that has three sides with one of the angles measuring 90 degrees.

Given an angle and the length of the adjacent side, we are to determine the value of the hypotenuse using cos.

Cos = adjacent / hypotenuse

cos 33 = 6 /h

h = 6 / cos 33

h = 6 / 0.83867

h = 7.15

Answer:35in.

Step-by-step explanation:

I reccomend splitting it into sections when given problems like this.

The smaller two rectangles would be 5in * 2in which is 10in then just add them together.

For the bigger one, you'd do 5-2 in order to get the missing inches which will be 3+2 once added 5in*3in is 15in.

Finally, add 15+10+10 (15=The middle rectangle and 10=the sides)

Answer:

Break it up into pieces. The answer is 35in^2

Step-by-step explanation:

I took the first rectangle you see which is 5in by 2. Multiply that and you get 10

I then took the second one and is the 5 in by 3in. Multiply those and you get 15

The last one is the exact same as the first one

Add the areas all together and you get the area of the whole shape

Answer:

16.4 m²

Step-by-step explanation:

length = 4.6 m

breadth = 360 cm = 360 ÷ 100 = 3.6 m

Perimeter = 2*(l + b)

                 = 2 * ( 4.6 + 3.6)

                 = 2 * 8.2

                  = 16.4 m²
