In this question, it is necessary to first check all the details that are already provided in the question. Then after they are noted down the final thing required is to find the answer to the question by correct calculations.
Distance for which the truck traveled = 280 kilometers
Time taken to travel the given distance = 4 hours.
Then
Speed of the truck = Distance traveled/Time taken
= 280/4 km/hr
= 70 km/hr
So the truck was traveling at a speed of 70 kilometers per hour. This is the answer to both the questions that have been put up. So there is no need for any kind of second calculation.
Step-by-step explanation:
A voluntary response sample is defined as a type of sample made up of self-chosen participants. These participants volunteer to take part in different research studies to share their opinions on topics that interest them. A voluntary response sample is made up of persons who volunteer to take research surveys.
So we have:
xk = v + w solve for x
divide both sides by k to isolate the variable x:
x = (v+w)/k
^^This is your answer!
Hope I helped!
Answer:

Step-by-step explanation:
As per the given question
As we know that
f(x) and x are related by following equation

where
b is the common ratio
Now first we have to compute the value for b which are as follows


Like if we take the ratio by this method than it comes 1.25
Therefore the common ratio, b = 1.25
So,
a = 5,120
Hence, the equation which model the relationship between the number of weeks and the number of viewers is

Answer: 6
Step-by-step explanation: Gets x by itself.
