Answer: 110 -10x
Step-by-step explanation:
You do pemdas
So 11•10 = 110
Then -10•x = -10x
And then you get
110-10x
Hello! To find the unit rate in miles per gallon, all you have to do is divide the amount of miles by the amount of gallons. 2½ is 2.5 in decimal form. 50/2.5 is 20. There. The unit rate is 20 miles per gallon.
Answer:
Category Relative Frequency
male survivors 17.3%
males who died 63.7 %
Female survivors 15.1 %
Females who died 3.8%
Step-by-step explanation:
- The relative frequency is the proportion of the number of times the event occurs to the total number of trials.
Given : Total people on ship = 2274
Number of male survivors = 394
⇒ Relative Frequency of male survivors =
In percent ,
Number of males who died =1449
⇒ Relative Frequency of male who died =
In percent ,
Number of female survivors =344
⇒ Relative Frequency of female survivors =
In percent ,
Number of females who died = 87
⇒ Relative Frequency of females who died =
In percent ,
Hence, the complete table would be :
Category Relative Frequency
male survivors 17.3%
males who died 63.7 %
Female survivors 15.1 %
Females who died 3.8%
Answer :
That’s it, the probability of getting tail on a single coin toss times the number of observations.
In this case, 1/2 * 72 = 36
However, there’s something called chance error. How much do you expect the result to differ from the expected value? It can be calculated as follows:
The Standard Deviation of this experiment is √(0.5)(0.5) =0.5
The Standard Error is √72 (0.5) ≈ 4.18330 round to the nearst tenth is 4
So, the expected value is 36, give or take 4.
And since the number of tails in a toss coin experiment is normally distributed, then you can expect the number of tails to be between -2 and +2 SEs from the expected value 95% of the time.
In other words, if you repeat this experiment a large number of times, you can expect to obtain between 27 and 43 tails 95% of the time.
Hope this helps
