Answer:
A. 10 cm
Step-by-step explanation:
In a right angled triangle, a² + b² = c² where c is the diagonal or hypotenuse. If you split a rectangle diagonally into two right angle triangles, the a and b of both triangles would be the same length. Therefore, the c or diagonals would also be the same length - 10 cm.
Hope this helps!
Answer:
B
Step-by-step explanation:
The probability of obtaining a 3 is
P(3) = 
Then after 30 spins the predicted number of times it should land on 3 is
30 ×
= 5
It’s 55, plug in the numbers and the equation is 5(3)^2 + 4(2.5) then
5(9)+10 lastly
45+10=55
x ≤ -2
