Step-by-step explanation:
Let X be the average speed of a car driving down freeway
Given that X is normal with mean as 70mph with a standard deviation of 5mph.
To convert to Z score we do

a) the probability that a randomly selected car is driving more than 77mph

b) probability that a randomly selected car is driving between 65 and 69 mph
= 
c) the probability that a randonly selected car is driving between 67 and 77mph
=
d) the probability that a randomly selected car is driving less than 77mph

Answer:
Step-by-step explanation:
hello :
g√ 108 =√ 3/g means : g² = √ 3/√ 108
g² = √(3/108)
g² = √(1/36)
g² = √(1/6)²
g² = 1/6
g = 1/√6 or g = - 1/√6
The equivalent expression is 
<h3>How to determine the equivalent expression?</h3>
The expression is given as:
rootindex 5 startroot 1,215 endroot superscript x
Rewrite properly as:
![\sqrt[5]{1215^x}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B1215%5Ex%7D)
Apply the law of indices

Hence, the equivalent expression is

Equality Properties
Step-by-step explanation:
<u>Step 1: Define</u>
4x - 12 ≤ 16 + 8x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4x on both sides: -12 ≤ 16 + 4x
- Subtract 16 on both sides: -28 ≤ 4x
- Divide 4 on both sides: -7 ≤ x
- Rewrite: x ≥ -7
Here we see that any value <em>x</em> greater than or equal to -7 would work as a solution to the inequality.
∴ our answer is -7.
