Answer:
A = 70 units²
Step-by-step explanation:
Since all 4 sides are congruent then figure is a rhombus
The area (A) of a rhombus is calculated as
A = × d₁ × d₂ ( d₁ and d₂ are the diagonals )
Here d₁ = 7 + 7 = 14 and d₂ = 5 + 5 = 10 , then
A = × 14 × 10 = 7 × 10 = 70 units²
Answer:
a.) Expected value on earning points= 21
b.) Expected value on earnings for composites = -1
Step-by-step explanation:
Expected value = [(6*1 + 6*2 + 6*3 + 6*4 + 6*5 + 6*6 ) ]* (1/6) = 6*(7)/2 = 21
b.) how many composite numbers from 1 to 6
4 and 6
so...
Expected Value of earning = [(-6*1 - 6*2 - 6*3 + 6*4 - 6*5 + 6*6 ) ]* (1/6) =
-1 - 2 - 3 + 4 - 5 + 6 = -1
Answer: it would be D)
Step-by-step explanation:
the answer is D) because if you multiply 12 by 2 its 12 and she adds one more so it is 25 tickets in 12 days.
Make sure that the line passes through -13 when it hits the y axis also make sure the line is going upwards, it is hard to explain, can you post the other questions?
Answer:
4x^2-81y^2 is NOT a perfect square trinomial, factored. You know this because if you factor this to (2x+9y)(2x-9y) then you will see that the signs between terms in the parenthesis are DIFFERENT.

Taking notes as you go through the course will help you retain and process the information much better than getting "help" from a site that is probably badly named.
