Answer:

This statement is false.

Step-by-step explanation:

You will use the mid point formula 15 times as there are 15 divisions needed to break it up into 16 intervals.

If you use the method 16 times, it will divide the line segment in 17 times.

The formula is given by:

$(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )$

The first sampling method is Convenient Sampling. It is biased sampling and it is not representative of a random sample.

The second sampling method is Systematic Sampling. If this method of sampling is drawn from the population, it is an efficiently randomized sampling method.

Let us review the given answers.

1. Both samples should be exactly the same.
INCORRECT

2. Neither sample will be representative.
Because the second sampling method can be random, this answer is
INCORRECT.

3. The first sampling method, ..., is the most representative,
INCORRECT

4. The second sampling method, ..., is the most representative.
CORRECT

Answer:

We would advise her to choose Country Route because in this route time consistent between 15 and 18 minutes.

Step-by-step explanation:

We are given that Jean lives about 10 miles from the college where she plans to attend a 10-week summer class. There are two main routes she can take to the school, one through the city and one through the countryside.

Jean sets up a randomized experiment where each day she tosses a coin to decide which route to take that day. She records the following data for 5 days of travel on each route.

Country Route - 17, 15, 17, 16, 18 (in minutes)

City Route - 18, 13, 20, 10, 16 (in minutes)

Now, we have to decide which route is better for Jean to go to college.

As we can see from the data that the Country route timings is consistent between 15 to 18 minutes which means most of the times she will reach college between these minutes only.

While on the other hand, we can observe that City route timings are very much consistent as it has a low value of 10 minutes and high value of 20 minutes which means Jean can't be sure that at which time she will reach college.

Hence, we would advise her to choose Country route.

Jerry makes $40,000 a year working at a nearby factory. He gets two weeks paid vacation per year, plus five other paid holidays.

JulijaS [17]

Answer:

Vacation pays are not included in salaries. Therefore, Jerry's calculation is wrong.

Step-by-step explanation:

Given is :

Jerry makes $40,000 a year working at a nearby factory.

He gets two weeks paid vacation per year, plus five other paid holidays.

So total paid holidays become = $14+5=19$ days

Subtracting 19 from 365 days and assuming that Jerry works for 365 days a year.

We get = $365-19=346$ days

So, his per day salary will be = $\frac{40000}{346}= 115.60$

Vacation pays are not included in salaries. Therefore, Jerry's calculation is wrong.

Find the quotient of 2,300 and (0.4 · 10^-8). In your final answer, include all of your calculations.

Alex777 [14]

Answer:

5.75x10^11

Step-by-step explanation:

quotient of 2,300 and (0.4x10^-8) is

2,300 ÷ (0.4x10^-8)

2300 = 2.3x10^3

We now have

2.3x10^3 / 0.4x10^-8

= (2.3/0.4) x ( 10^(3 - (-8))

= 5.75 x (10^(3+8))

= 5.75 x (10^11)

= 5.75x10^11
