<h2>
Question:</h2>
Write an expression that can be used to find the sum of the most common and least common lengths of alien fingers.
<h2>
Answer:</h2>
5 + 1 = 6
<h2>
Step-by-step explanation:</h2>
(MCL) Most Common Length = 5
(LCL) Least Common Length = 1
MCL + LCL =
5 + 1 = 6
If the person did not vote it can be:
30/100 (30%) people in the city are conservatives, and only 65/100 voted - so 45/100 did not voted.
Liberals are 50% of the city population (1/2), and 82/100 of them voted, so 100/100-82/100=8/100 did not voted!
So let’s make 2 probability events:
1) A person did not voted
2) a person is liberal
Probability that the person is a liberal: 1/2
Person didn’t voted and it’s a liberal:
1/2*8/100= 8/200=4/100 [*]
[*] To count the probability of two probability events you need to multiply them.
67.50? i think... maybe double check though.
Answer:
0.6848
Step-by-step explanation:
Mean of \hat{p} = 0.453
Answer = 0.453
Standard deviation of \hat{p} :
= \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} = \sqrt{\frac{0.453(1-0.453)}{100}} = 0.0498
Answer = 0.0498
P(0.0453 - 0.05 < p < 0.0453 + 0.05)
On standardising,
= P(\frac{0.0453-0.05-0.0453}{0.0498} <Z<\frac{0.0453+0.05-0.0453}{0.0498})
= P(-1.0044 < Z < 1.0044) = 0.6848
Answer = 0.6848
