First you plug everything in to get
2a=-5 (1)^2+9 you do the powers and multiply
2a=-5 (1)+9
2a=-5+9
2a=4
a=2

Answer:
0.125 is the probability of getting a heads on each of the three coins on the one toss of the three coins.
Step-by-step explanation:
We are given the following in the question:
Event: flipping three coins at the same time
We can write the sample space as:
S:{TTT, THH, HTH, HHT, TTH, HTT, THT, HHH}
We define probability as
We have to evaluate the probability of getting a heads on each of the three coins on the one toss of the three coins

0.125 is the probability of getting a heads on each of the three coins on the one toss of the three coins.
Answer:
Division and multiplication are inverse operations. This means they "undo" each other. You can check your answer by multiplying the quotient by the divisor. You should get the dividend.
have a great day :)
Answer:
15
Step-by-step explanation:
The base would be 3*3, as it's a square. There are 4 triangles, and the area of each triangle is 1*3/2=1.5. 1.5*4+9=15.
