80 m is distance traveled
Step-by-step explanation:
if object moves at 20m/s, then in 4 seconds the expression 20 x 4 is used to get 80. 80 m traveled
The total number of people in the city surveyed by Annette= 480 people.
Step-by-step explanation:
Let 'X' be the Total Number of people Annette surveyed.
Out of Total people in the city, only <u>180 people are not interested</u> in a new shopping mall.
Therefore, it is given in the question that <u>180 is 37.5% of Total number of people surveyed (X).</u>
step 1: 180= (37.5/100)*(X)
step 2: X= (180*100)/37.5
step 3: X= 18000/37.5
step 4: X= 480
Answer:
0.0433
Step-by-step explanation:
Since we have a fixed number of trials (N = 25) and the probability of getting heads is always p = 0.05, we are going to treat this as a binomial distribution.
Using a binomial probability calculator, we find that the probability of obtaining heads from 8 to 17 times is 0.9567 given that the con is fair. The probability of obtaining any other value given that the coin is fair is going to be:
1 - 0.9567 = 0.0433
Since we are going to conclude that the coin is baised if either x<8 or x>17, the probability of judging the coin to be baised when it is actually fair is 4.33%
