Answer:
Divide the standard deviation of the sample measures by 8
Step-by-step explanation:
Given
measurements in data set=500
measurements in sample=64
Standard error of sample=?
As per the formula of standard error
Standard error= standard deviation/ square root of the number of measurements
= σ/√n
Here as we need to find standard error of the sample hence n=64
therefore √64= 8
The above equation will become:
standard error of the sample= σ/8 i.e. Divide the standard deviation of the sample measures by 8!
Answer:y=3x+2
Step-by-step explanation:
y=mx+c
m=slope=3
c=y-intercept=2
Our equation would be y=3x+2
3 1/5 = y - 12/25
Make 3 1/5 an improper fraction.
16/5 = y - 12/25
Add 12/25 to both sides.
16/5 + 12/25 = y
Make a common denominator.
80/25 + 12 / 25 = y
92 / 25 = y
3 17/25 = y
Hope this helps!
By using the trial method we get a total number of trials taken by Charlie to see both sides of both the coins is 4.
<h3>What is probability?</h3>
Probability is the name of the area of mathematics that deals with the examination of random events. The ratio of favorable occurrences to the total number of events is used to calculate an event's probability.
P(E) = F(E)/T (E)P(E)
It stands for the probability that an event will occur.
F(E) = Amount of favorable occurrences
Total number of trials (T(E))
Given that Charlie has 2 fair coins.
If he tosses the pair of coins simultaneously, then the number of samples can be HH, HT, TH, TT.
So to see both sides of both the coins he should toss the coin four times.
