There is 3600 seconds per hour.
Multiply the speed per second by 3600 to get the speed in miles per hour then convert to kilometer/hour.
4.9 * 3600 = 17,640 miles per hour
17,640 x 1.6 = 28,224 kilometers per hour
Options :
(A.) y=558-273x (B.) y=264+142x (C.) y = 55.8 +2.79x (D.) y= -26.4-1.42x
Answer:
C.) ŷ = 2.79X + 55.8
Step-by-step explanation:
Given the data:
cost (x): 9 2 3 4 2 5 9 10
Number of products sold: 85 52 55 68 57 86 83 73
Using the online regression calculator to generate a linear regression plot of the given data: the model obtained is given below
ŷ = 2.79X + 55.8
With y being the predicted or dependent variable
Slope or gradient of the line = 2.79
X = the independent variable
55.8 = the intercept.
By applying Exponential laws, option no. c which is, 
stands correct.
What are exponents?
- A number's exponent indicates how many times that number has been multiplied by itself.
- However many times multiplying a given number is indicated by its exponent. Powers and indices are other names for exponents.
- An indication of the action of elevating to a power that is printed above and on the side of a mathematical form
- Exponent-related problems are solved using the rules of exponents or the properties of exponents. These characteristics are regarded as fundamental exponents rules that must be adhered to when solving exponents.
Given that,
Applying the law of exponents to the given expression,
Putting the given value in the above expression, we get,
Hence, by applying Exponential laws, option no. c which is, stands correct.

<u>Answer:</u>
The data sets can be same.
<u>Step-by-step explanation:</u>
If there are two sets of data having the same measures of central tendency, then there is a possibility that the data sets the same
The two data sets could be the same but its not necessary. It is possible for data sets to be different in term of their spread but still have the same measures of center.
The measures of spread for the two data sets could be different.
