Answer: option d.

Step-by-step explanation:

Given the inequality:

6y - 8 > 4y + 26

The procedure you can use to solve it is:

1. Subtract 4y from both sides:

6y - 8-(4y) > 4y + 26-(4y)\\\\2y-8>26

2. Add 8 to both sides:

2y-8+(8)>26+(8)\\\\2y>34

3. Divide both sides by 2:

\frac{2y}{2}>\frac{34}{2}\\\\y>17

 Therefore, the solution in Set Notation is:

{y |\ y > 17}

Answer:

d)  

{y | y > 17}

Step-by-step explanation:

6y – 8 > 4y + 26

=>6y-4y-8 > 4y+26-4y

=>2y-8>26

=>2y-8+8>26+8

=>2y>34

=>y>17

The number of bacteria in culture grows 80% each hour. Suppose. There are 250 bacteria in the original culture.
Flauer [41]

Answer:  (a) y = 250(1.8)ˣ     (b) 89,262 bacteria

<u>Step-by-step explanation:</u>

Use the exponential growth formula   y = a(b)ˣ     where

  • a = Initial Value
  • b = 1 + r  (for growth) or 1 - r for decay
  • r = rate (convert percent to a decimal)

a)    Given: a = 250,    r = 80% (.80) → b = 1.8

       y = 250(1.8)ˣ

b)  Given: x = 10

     y = 250(1.8)¹⁰

     y = 89,261.68   =  89,262 (rounded to the nearest whole number)

A mechanic sells a brand of automobile tire that has a life expectancy that is normally​ distributed, with a mean life of 27 com
Harrizon [31]

Answer:

Tires that wear out by approximately 24307.8 miles will be replaces free of charge.        

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 27,000 miles

Standard Deviation, σ = 2100  miles

We are given that the distribution of life expectancy is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.10

P( X < x) = P( z < \displaystyle\frac{x - 27000}{2100})=0.10  

Calculation the value from standard normal z table, we have,  

\displaystyle\frac{x - 27000}{2100} = -1.282\\\\x = 24307.8

Tires that wear out by approximately 24307.8 miles will be replaces free of charge.
