Answer:
The probability that neither person is left-handed is 88.36%, that only one is left-handed is 5.64%, and that both are left-handed is 0.36%.
Step-by-step explanation:
Supposing that 6% of people are left handed and supposing two people are picked at random, to find the probability that 0, 1 or 2 people are left-handed, the following calculation must be performed:
100 - 6 = 94
0 left-handed people = 0.94 x 0.94 = 0.8836 = 88.36%
1 left-handed person = 0.94 x 0.06 = 0.0564 = 5.64%
2 left-handed people = 0.06 x 0.06 = 0.0036 = 0.36%
Therefore, the probability that neither person is left-handed is 88.36%, that only one is left-handed is 5.64%, and that both are left-handed is 0.36%.
A pendulum that swings fully once in 1.9 seconds has a length of 2.93 feet.
<h3>What is the length of a pendulum?</h3>
A basic pendulum is a machine in which the point mass is hung from a fixed support by a light, inextensible string.
Length of pendulum is defined as the distance between the point of suspension to the center of the bob and is denoted by " 1 ".
Given the equation:
![$$T=2 \Pi \sqrt{\frac{L}{32}}$$](https://tex.z-dn.net/?f=%24%24T%3D2%20%5CPi%20%5Csqrt%7B%5Cfrac%7BL%7D%7B32%7D%7D%24%24)
where L is the length in feet and T is the time in seconds.
Given that T = 1.9sec,
Hence:
![$$T=2 \Pi \sqrt{\frac{L}{32}}$$](https://tex.z-dn.net/?f=%24%24T%3D2%20%5CPi%20%5Csqrt%7B%5Cfrac%7BL%7D%7B32%7D%7D%24%24)
L = 2.93 feet
A pendulum that swings fully once in 1.9 sec has a length of 2.93 feet.

Answer:y=4 x=3
Step-by-step explanation:9(-9+3y)-4y=11
-81+27y-4y=11 23y=92 y=4 x=3
Answer:That is not the solution explanation: because if you put the 0 in place of the x in the equation, y would have to equal 6. If you put the -2 in place of the y then x would have to equal 8.
Simpler explanation: 0 + -2 = -2 not 6
