You would just break each one into 2 separate equations and solve for x/r. Then write the answer in between the two inequality signs- so the answers for 9 and 11 would look like this, just fill in the blanks with the answer you got: 3<span>≤____<5, 2>___>-2.
</span>
0<span>≤x-2<3
1</span><span>≤x-2 and x-2<3
</span><span>-1>2r-5>-9
-1>2r-5 and 2r-5>-9
this one just solve each one for z.
2z-1</span>≤5 or 3z-5>10
<span>z≤3 or x>5</span>
Answer:
d = 0.4
Step-by-step explanation:
Given
- 10(d + 1) = - 14 (divide both sides by - 10 )
d + 1 = 1.4 ( subtract 1 from both sides )
d = 0.4
<2 and <3 are supplementary angles...therefore they must equal 180°
since <2 = 125
you can find the measure of <3 by subtracting the measure of <2 from 180°
180 - 125 = 55° < answer
hope this helps :)

Answer:
2.35 calls
Step-by-step explanation:
The presented scenario can be modeled by a Poisson distribution with an average number of calls (μ) of 5.5 during the noon hour on Mondays.
Therefore, the standard deviation for the number of calls received, X, is given by:
The standard deviation of X is 2.35 calls.
