A salesperson obtained a systematic sample of size 30 from a list of 750 clients. To do so, he randomly selected a number from 1
n200080 [17]

Answer:

B. 17,42, ..., 742

Step-by-step explanation:

In the systematic sampling after choosing the first entry every kth entry is selected according to given procedure

starting entry, starting entry+k, starting entry+2k,..., starting entry+(n-1)k.

Where n denotes the sample size.

we are given that starting entry is 17, sample size is 30 and k=25.

Then the number corresponds to selected clients are

17, 17+25, ..., 17+(30-1)25

17, 42, ..., 742

An experiment repeated 5 times is more reliable than an experimment repeated 20 times
shutvik [7]

Answer:

The given statement is false

Step-by-step explanation:

Given that an experiment repeated 5 times is more reliable than an experiment repeated 20 times.

The statement is false.

Any result found by way of experiment will be more reliable if more number of trials are done.  

For example, consider toss of a coin.  If we try for 2 times, we may get prob for head as 0 sometimes 1/2 or sometimes 1. This is because 2 is very short number of trials to decide.  But when you increase to 10, you may get more reliable.  SO if number of repititions increase, the more reliable the results would be.

In Lucille’s class, 35% of the students have blond hair. There are 20 students in the class. How many students have blond hair.
MrRissso [65]

Answer:

7 the answer is 7

Step-by-step explanation:

1. We assume, that the number 20 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 20 is 100%, so we can write it down as 20=100%.

4. We know, that x is 35% of the output value, so we can write it down as x=35%.

5. Now we have two simple equations:

1) 20=100%

2) x=35%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

20/x=100%/35%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 35% of 20

20/x=100/35

(20/x)*x=(100/35)*x       -

20=2.85714285714*x       -

20/2.85714285714=x

7=x

x=7

now we have:

35% of 20=7

we multiply both sides by x

then we divide both sides by 2.85714285714 to get x
