Answer:
R2 = 6.44
T2 = 8.82
Whole = 30.42
Step-by-step explanation:
R1 = 2.8 X 3.1
T1 = (1/2) X (2.4) X (5.4)
R2 = (5.4-3.1) X (2.8) = 6.44
T2 = (1/2) X (11.7-5.4) X (2.8) = 8.82
Whole = (1/2) X (11.7) X (2.4+2.8) = 30.42
Answer:
( -1 , 26)
Step-by-step explanation:
So since you need to find the other endpoint, you would follow these steps:
1.)
2.) 8 = 9 + x ( you just multiplied the 2 to the 4 to get 8)
3.) -1 = x (just solve it like a regular equation, so just subtract 9 on both sides to get rid of it and that leaves you with -1 = x)
You took the x values of both points and put them in the equation.
And its the same for y
1.)
2.) 16 = -10 + y
3.) 26 = y (you added the 10 on both sides because the 10 was negative and that took the 10 out and so it left you with 26 = y)
Answer:
755 gram lighter
Step-by-step explanation:
Convert 1.1kg into gram by multiplying it with 1000
1.1 x 1000= 1100 and we take this amount and subtract it with 345g
1100-345= 755g
Answer:
Example:
A bag contains 3 black balls and 5 white balls. Paul picks a ball at random from the bag and replaces it back in the bag. He mixes the balls in the bag and then picks another ball at random from the bag.
a) Construct a probability tree of the problem.
b) Calculate the probability that Paul picks:
i) two black balls
ii) a black ball in his second draw
Solution:
tree diagram
a) Check that the probabilities in the last column add up to 1.
b) i) To find the probability of getting two black balls, first locate the B branch and then follow the second B branch. Since these are independent events we can multiply the probability of each branch.
ii) There are two outcomes where the second ball can be black.
Either (B, B) or (W, B)
From the probability tree diagram, we get:
P(second ball black)
= P(B, B) or P(W, B)
= P(B, B) + P(W, B)
