Systematic random sampling involves a selection technique in which samples are selected at fixed intervals. Hence, the true statement is "Systematic random sampling can be used, even if knowledge of the entire population is not known."
Systematic random sampling would fail to catch all patterns because the samples are selected at periodically at fixed intervals, hence, the possibility of missing pattern is very possible. Starting point could be at any point and hence, might not be the first sample in the population.However, without knowing the entire population size, systematic random samples could be selected from the population.

Mila bought slippers worth PHP240.00 with a discount of 25% how much money will she pay
A.PHP 180.00
B.PHP 200.00
C.PHP 220.00
Answer:
A.PHP 180.00
Step-by-step explanation:
Given the following data;
Selling price = PHP240.00
Discount = 25% = 25/100 = 0.25
To find the amount she paid;
Discount price = 240 * 0.25
Discount price = PHP60
Amount paid = Selling price - discount price
Amount paid = 240 - 60
Amount paid = PHP180
Therefore, Mia would pay PHP180 for the slippers.

65,823 - b=41,000 what is the value of b
Answer:
24,823
Step-by-step explanation:
Since we know the answer and the what we're subtracting from we can make an equation like this 65,823 - b = 41,000. Now you solve it by subtracting 65,823 - 41,000 = b. 24,823 = b because if we were to add the smaller numbers like this: 41,000 + 24,823 we would get 65,823 making our answer correct.

What is the area, in square feet, of the rectangle shown below?
Answer:
D
Step-by-step explanation:
= 34/5 × 19/4
= 646/20
= [tex]32 \frac{6}{20} [/tex]
The area of the given rectangle is [tex]32\frac{6}{20}[/tex] square feet
For better understanding check the calcualtion here .
Calcualtion :
Area of the rectangle is the space inside the given triangle .
Formula : Formula to find the area of the triangle is length times width
Length and width are given as mixed fractions
Lets convert mixed fractions into improper fractions
[tex]Length =6\frac{4}{5}=\frac{6 \cdot 5+4}{5}=\frac{34}{5} \\Width=4\frac{3}{4}=\frac{4 \cdot 4+3}{4}=\frac{19}{4}[/tex]
Now we find out the area
[tex]Area= length \cdot width \\Area=\frac{34}{5} \cdot \frac{19}{4} \\Area= \frac{646}{20}[/tex]
Now we divide the number and find out the quotient and remainder
[tex]Area= \frac{646}{4} \\Quotient = 32 \\remainder =6\\Area= 32\frac{6}{20}[/tex]
The area of the given rectangle is [tex]32\frac{6}{20}[/tex] square feet

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 7.5 parts/million (ppm). A researcher believes that the current ozone level is not at a normal level. The mean of 24 samples is 7.8 ppm with a standard deviation of 0.7. Assume the population is normally distributed. A level of significance of 0.02 will be used. Find the value of the test statistic. Round your answer to three decimal places.
Answer:
The value of the test statistic is [tex]t = 2.1[/tex]
Step-by-step explanation:
Our test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the expected value, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
The level of ozone normally found is 7.5 parts/million (ppm).
This means that [tex]\mu = 7.5[/tex]
The mean of 24 samples is 7.8 ppm with a standard deviation of 0.7.
This means that [tex]X = 7.8, \sigma = 0.7, n = 24[/tex]
Test Statistic:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]t = \frac{7.8 - 7.5}{\frac{0.7}{\sqrt{24}}}[/tex]
[tex]t = 2.1[/tex]
The value of the test statistic is [tex]t = 2.1[/tex]

The cost of shipping a package is $2.75 per pound. Jeremy wants to ship a package that has a mass of 15 kg. How much will it cost Jeremy to ship this package? Use 1 kg = 2.2 lbs.
Answer:
$90.75
Step-by-step explanation:
First we convert kilograms to pounds.
1 kg = 2.2 lb
15 kg = 15 * 2.2 lb = 33 lb
Cost of shipping: $2.75/lb
Cost of shipping 33 lb: 33 lb * 2.75/lb = $90.75
Answer: $90.75

As a salesperson for an electronic parts distributor, you are given two options for your salary structure. The first option has a base salary of $300 a week plus 4% of all sales made. The second option has a base salary of $100 plus 7.5% commission on all sales. Find the sales amount that will result in the two options having the same weekly salary.
Answer:
The amount of sale is approximately 5714.
Step-by-step explanation:
Let x be the sales made that will result to the same salary and let y be the same weekly salary.
We can represent both salaries as follows:
300 + 0.04x = y
100 + 0.075x = y
Subtracting the second equation from the first, we have:
200 – 0.035x = 0
0.035x= 200
x = 200/0.035
x ≈ 5714.
Therefore, the amount of sale is approximately 5714.
The diameter of a circle is 55 inches.
Find the length of its radius.
Answer:
inches
Answer:
27.5 inches
Step-by-step explanation:
The circle's "radius" refers to the distance from the center towards the circumference. Once the diameter of a circle is given, it is easy to get the radius. In order to get the length of the circle's radius, all you have to do is to divide the diameter (55 inches) into two.
55 inches ÷ 2 = 27.5 inchesTherefore, the circle's distance from the center towards the circumference is 27.5 inches. This is the radius.
