79+82+85+91+97+73+88+87+85+92+90+85+86+91+94+85+92=1482 divided by 17 ( the amount of numbers) = 87.17
Answer:
The value of 27, because it’s greater than 26.7 and less than 29.3.
Step-by-step explanation:
You should find the confidence Interval at 95%
The formula to apply is;
C.I= x±z*δ/√n
where C.I is the confidence interval, x is the mean of the sample, z is the z* value from the standard normal distribution for 95% confidence interval, δ is the standard deviation and n is the sample size
Substitute values in the formula
Find δ/√n
Calculate z*δ/√n
C.I= 28±1.2652
Upper limit is = 28+1.2652=29.2625
Lower limit is =28-1.2652=26.7348
Solution
The value 27 is within 95% confidence interval because it is greater than 26.7 and less than 29.3
Both are functions. Try not to get tripped up on notation of functions. They are they same, just written differently.
f(x) = 3x-10 is the same as 0=3x-10
2x+7y=28 is the same as 2x+7y-28=0
Just one will give you a line and the other will give you a circle. If you are ever unsure, plug them into a graphing calculator and see what you get back.
To answer this item, we are to convert one of the unit to
the other. The approach to answering is to convert the 34 degrees Celsius to
kelvin by the equation,
T = C + 273.15
Substituting the known value,
<span> T = (34) + 273.15
= 307.15 K</span>
Since 307.15K is greater than 300K then, the greater value
is 34 degrees C.
ANSWER: 34 degrees C
