Sample size is given as 1910 people
<em>4.confidence interval </em>
Confidence interval is given ±3 around the point of estimate
Answer:
x=4 cm
Step-by-step explanation:
x=smallest side
4x=hypotenuse
4√15=third side
use the Pythagorean Theorem
(4x)^2=x^2+(4√15)^2
16x^2=x^2+240
16x^2-x^2=240
15x^2=240
x^2=240/15
x^2=16
x=√16
x=4 cm is the smallest side
the hypotenuse is 16 cm
the third side is 4√15 cm
If you mean you get them by diving them by 100 or something over 100(as in a fraction) that's the answer, I'm incredibly sorry if it is not what you meant!
The answer is D because the median is 4, the mean is 4, and the range is 4

my hands hurt, pls give brainilist and hope this helps
Step-by-step explanation:
Before leaving for work, Victor checks the weather report in order to decide whether to carry an umbrella. The forecast is “rain" with probability 20% and “no rain" with probability 80%. If the forecast is “rain", the probability of actually having rain on that day is 80%. On the other hand, if the forecast is “no rain", the probability of actually raining is 10%.
1. One day, Victor missed the forecast and it rained. What is the probability that the forecast was “rain"?
2. Victor misses the morning forecast with probability 0.2 on any day in the year. If he misses the forecast, Victor will flip a fair coin to decide whether to carry an umbrella. (We assume that the result of the coin flip is independent from the forecast and the weather.) On any day he sees the forecast, if it says “rain" he will always carry an umbrella, and if it says “no rain" he will not carry an umbrella. Let U be the event that “Victor is carrying an umbrella", and let N be the event that the forecast is “no rain". Are events U and N independent?
3. Victor is carrying an umbrella and it is not raining. What is the probability that he saw the forecast?
