Answer: 92
Step-by-step explanation:
Answer:
x > 10
Step-by-step explanation:
Add 3 to both sides.
I believe B. is your answer. If you use the ac method, you will multiply 8 and 3 which is 24. So now, what factors of 24 will give you 10?6 and 4
Now substitute

Now do factorization by grouping.

Therefore, your answer is (4x+3)2x+1)
Answer:
Step-by-step explanation:
Hello!
X: number of absences per tutorial per student over the past 5 years(percentage)
X≈N(μ;σ²)
You have to construct a 90% to estimate the population mean of the percentage of absences per tutorial of the students over the past 5 years.
The formula for the CI is:
X[bar] ±
* 
⇒ The population standard deviation is unknown and since the distribution is approximate, I'll use the estimation of the standard deviation in place of the population parameter.
Number of Absences 13.9 16.4 12.3 13.2 8.4 4.4 10.3 8.8 4.8 10.9 15.9 9.7 4.5 11.5 5.7 10.8 9.7 8.2 10.3 12.2 10.6 16.2 15.2 1.7 11.7 11.9 10.0 12.4
X[bar]= 10.41
S= 3.71

[10.41±1.645*
]
[9.26; 11.56]
Using a confidence level of 90% you'd expect that the interval [9.26; 11.56]% contains the value of the population mean of the percentage of absences per tutorial of the students over the past 5 years.
I hope this helps!
Answer:
Ok time to get math on
So this would be D
A non-filled in dot means < or > (depending where arrow is pointing)
A filled in dot means ≤ or ≥ (depending where arrow is pointing)
if an arrow points right, then it would be greater than, if arrow points left.. Then its less than
So the graph line is showing that it cannot be equal to AND it is lesser than so the only answer choice that would make the most sense is D
A is greater than which is not the answer
B is only equal to which is way off
C is less than but it is equal which is wrong
D is the only right answer
Hope this helps! :)
