Answer:

<u>Option 4:</u> 10d + 5

Step-by-step explanation:

Given the algebraic expression, 5(2<em>d</em> + 1), which represents the fines per day, <em>d</em>, for overdue books.

In order to determine the equivalent algebraic expression of 5(2<em>d</em> + 1), we must distribute 5 into the terms inside the parenthesis:

5(2d<em> </em>+ 1)

= 5(2d) + 5(1)

\fbox{\textsf{= 10d + 5 }}

Therefore, the equivalent expression is: 10d + 5.

the mean household income for a certain state is $71,000 with a standard deviation of $10,000 assuming a normal distribution abo
Vesnalui [34]

Answer:

About 95% of households have an income over $54,550

Step-by-step explanation:

95% is a probability of around 0.95

So we start by calculating the z-score with a probability of 0.95

We can use the standard normal distribution table for this

the z-score is -1.645

Mathematically;

z-score = (x-mean)/SD

-1.645 = (x-71,000)/10,000

10,000 * -1.645 = x-71,000

-16450 = x - 71000

x = 71,000 - 16450

x = 54,550
