-2+1/2 (6) I'd 1 so A is correct
Answer:
X1=-4+4i
X2=-4-4i
Step-by-step explanation:
X^2+8x+32=0
Δ=b^2-4ac=8^2-4(32)=-64<0
X1=(-b-i√Δ) /2a=(-8-8i)/2=-4-4i
X2=(-b+i√Δ) /2a=(-8+8i)/2=-4+4i
Tess and Jack are both correct with their claims
<h3>How to determine who is correct?</h3>
The attached image completes the question
From the complete question, we have the following highlights
- The shape has equal side lengths
- The angles at the vertices of the shape are right angles
The above properties represent a square
A rhombus can also have the above properties when the vertices are at 90 degrees
Hence, Tess and Jack are both correct with their claims

Answer: The required probability is 0.414.
Step-by-step explanation:
Since we have given that
Probability of taxis in a certain city by Blue Cab P(B)= 15%
Probability of taxis by Green Cab P(G) = 85%
Let A be the event that eyewitness said that vehicle was blue.
P(A|B)=0.80
P(A|G)=0.80
P(A'|B)=0.20=P(A'|G)
Using the "Bayes theorem":
Probability that the taxi at fault was blue is given by

Hence, the required probability is 0.414.
