Answer:

b)the results of the survey cannot reliably be extended and generalized.

Step-by-step explanation:

Voluntary sampling is a type of convenience sample; it is convenient for the researcher to perform.

However, voluntary sampling can lead to bias; usually only people who feel strongly one way or the other about the survey will volunteer to be members of a sample.

Since there is a possibility of bias, the results of the survey cannot reliably be extended and generalized.

laila [671]

Step-by-step explanation:

The greatest common factor (GCF) is the largest common factor that the numbers share. Here, 8 is the largest common factor of 16 and 24. So the GCF of 16 and 24 is 8.

Answer:

Parallelograms I, II, and IV

Step-by-step:

Area of parallelograms:

I. A=3*5=15 units squared

II. A=5*3=15 units squared

III. A=4*4=16 units squared

IV. A=5*3=15 units squared

So, parallelograms I, II, and IV have the same area of 15 units squared.

Answer:

A and C

Step-by-step explanation:

Both angles j and m share one common side and vertex with angle k. Angle n only shares a vertex and not a side with angle k, so it is not adjacent.

Look at the picture ASAP

goldenfox [79]

Using the Laws of Cosine, we obtain $C^2 = 55^2+108^2-2(108)(55)*cos(59)$ , which c approximately equals 153.44. So Line AB ≈ 153.44 meters.

A train leaves boston and travels toward its destination at a speed of 60 mph. One hour later, an express train leaves Boston an

Margarita [4]

Taking into account the supplied speeds, Boston is from the destination to:

240 miles

<h3>Calculation of the distance between Boston and Place of Destination</h3>

To identify the distance between Boston and the destination of the trains, it must be remembered that the <u>speed</u> mentioned for each one is a reference to the distance traveled per hour, therefore, after each hour, each train will travel :

Regular train: 60 miles
Express train: 80 miles

According to the information given, when the express train leaves, the regular train has a 60-mile lead, which is getting shorter hour by hour because the express train travels 20 miles per hour more than the normal train.

Therefore, in <u>three hours</u>, the express train would catch up with the regular train, calculating the distance thanks to the speed formula:

$Speed =\frac{Distance}{Time}$

And clearing the distance:

$Distance=Speed*Time$

$Distance=80\frac{miles}{hour}*3hours$

$Distance=240miles$

Therefore, the destination would be <u>240 miles</u> from Boston, which would take four hours by regular train and three hours by express train.
