Answer:
X=10
Step-by-step explanation:
You can subtract 180 by 110 to get 70. Then you can do 8x+30+70=180
Add 30+70 to get 100
Subtract 100 to 180 to get 80.
8x=80
You divide 8 from both sides which leaves you with x=10.
Answer:
Individuals with calcium level 8.7 mg/dL or low are considered with low calcium level and above that are not considered low.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 9.5 mg/dL
Standard Deviation, σ = 0.5 mg/dL
We are given that the distribution of calcium levels is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.05
Calculation the value from standard normal z table, we have,
![\displaystyle\frac{x - 9.5}{0.5} = -1.645\\\\x =8.6775\\x \approx 8.7](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7Bx%20-%209.5%7D%7B0.5%7D%20%3D%20-1.645%5C%5C%5C%5Cx%20%3D8.6775%5C%5Cx%20%5Capprox%208.7)
Thus, individuals with calcium level 8.7 mg/dL or low are considered with low calcium level and above that are not considered low.
Answer:
1
Step-by-step explanation:
For the top, you can write it as (2-b)^2 = (-1(b-2))^2 = (-1)^2(b-2)^2 = 1(b-2)^2 = (b-2)^2. Putting that back in, we get: ((b-2)^2)/((b-2)^2) = 1 because the top and bottom cancel.
I hope this helps! :)
Answer:
7π/6.
Step-by-step explanation:
The range in the third quadrant is π to 3π/2 ( or π to 1.5π) so its not π/3 or 3π/4.
5π/3 = 1.67π so it's not this one.
7π/6 = 1.167π so it's this one.
