Answer: discrete.

Step-by-step explanation:

Discrete variable

It is a variable whose value is evaluated by counting.

Example: Number of books published in a month.

Continuous variable

It is a variable whose value is evaluated by measuring ( not countable).

Example: Distance: 1.52 m

Since the number of dental visits a randomly chosen person had for the past 5 years is a countable.

here, Variable: Let X =number of dental visits a randomly chosen person had for the past 5 years

So, the random variable described is discrete.

Linda and Rob open an online savings account that has a 2.89% annual interest rate, compounded
sp2606 [1]

Answer:

FV= $34,222.33

Step-by-step explanation:

<u>First, we need to calculate the weekly interest rate:</u>

Weekly interest rate= 0.0289/52= 0.00056

<u>To calculate the future value (FV), we need to use the following formula:</u>

FV= {A*[(1+i)^n-1]}/i

A= weekly deposit

n= 15*52= 780

A= $35

FV= {35*[(1.00056^780) - 1]} / 0.00056

FV= $34,222.33

Solve:<br> -8(x - 3) + 5x &lt; 9(x + 12)<br> This is Algebra 1
Flauer [41]

Answer:

x>−7

Step-by-step explanation:

left side:

-8(x-3)+5x

distribute -8 into (x-3)

-8x+24+5x

combine like terms

-3x+24

right side:

9(x+12)

distribute 9 into (x+12)

9x+108

-3x+24<9x+108

Subtract 24 on both sides

-3x< 9x+108-24

combine like terms

-3x<9x+84

Subtract 9x on both sides

-3x-9x<+84

combine like terms again

-12x<84

Multiply both sides by -1 (reverse the inequality)

(-12x)(-1)>84(-1)

12x>-84

divide both sides with 12

\frac{12x}{12}>\frac{-84}{12}

x>−7

hope this helps

Look at the picture.....
tresset_1 [31]

Answer:

Step-by-step explanation:

y = a|x-h| + k

(h,k) is the vertex

There's no standard formula for absolute values. I just made it up as an example, pretty much.

Since a is negative, the function opens downward.

h = -2, k = 0, so the vertex is at (-2,0)
