Answer: x=3/4 x=-4
Step-by-step explanation:
(4x-3)(x+4)=0
4x-3=0
4x-3+3=0+3
4x=3
Divide both parts of the equation by 4:
x+4=0
x+4-4=0-4
x=-4

Answer:
Y = 3 And x = 3
Step-by-step explanation:
Because this is a 45 to 45 degree triangle, the 3 * (square root of 2 )/2 is y as well. Because this is a 45-45 triangle, x should be y (Square root of 2). Therefore, replacing y with 3 * (square root of 2 )/2 and multiply the square root of 2, the answer for x is 3. If I got something wrong please tell me, thanks.
Given:
Three coins are tossed.
Let the event H represents all Heads and the event K represents at least one Heads.
To find:
a. The probability that the outcome is all heads if at least one coin shows a heads.
b. P(K) = ?
c. P(H∩K) = ?
Solution:
If three coins are tossed, then the total possible outcomes are:
{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
Total outcomes = 8
Possible outcomes for all Heads = 1
Possible outcomes for at least one Heads = 7
Let the following events:
H = all Heads
K = at least one Heads.
Then,
Now,
a. The probability that the outcome is all heads if at least one coin shows a heads is:
Therefore, the probability that the outcome is all heads if at least one coin shows a heads is .
b.
c.
