The answer is 41 (Option A)


Expalanation

Given,
a = <7, 4>
b = <3, 5>

<span>We are told to find a ⋅ b (which is a scaler product)</span>


Taken that,

a = <x₁, y₁> 

b = <x₂, y₂>


a ⋅ b = x₁x₂ + y₁y₂

<span>a ⋅ b = (7 * 3) + (4 * 5)</span>

a ⋅ b = 21 + 20

a ⋅ b = 41 (OPTION A)

What is the median please help please help
Paladinen [302]

Answer:

54.5

Step-by-step explanation:

To find the median, first we have to put the numbers in ascending/increasing order.

43, 60, 50, 36, 58, 50, 73, 59, 69, 51 is your set

36, 43, 50, 50, 51, 58, 59, 60, 69, 73 is your set in order.

The median is the middle number of the data set. Your set has an even number of entries, so we have to average the 2 middle numbers, which are 51 and 58.

36, 43, 50, 50,     51, 58,         59, 60, 69, 73

51 + 58 = 109

109/2 = 54.5
