Answer:
y ≤ 3x- 1
Step-by-step explanation:
The line is solid, so your answer must have a ≤ or ≥ symbol. And the area below the line is shaded so you would also know you answer must have a ≤ or < symbol.

The factored expression ofx^3 - 7x^2 -5x +35 is (x^2 - 5)(x - 7)
<h3>What is an expression?</h3>
An expression is an algebraic term used for a mathematical statement that includes addition subtraction multiplication and division
x^3 – 7x^2 – 5x + 35
factor the given equation
x^2(x – 7) – 5(x - 7)
Factor out x - 7
(x^2 - 5)(x - 7)
Therefore, the factored expression is (x^2 - 5)(x - 7)

Answer:
68.268%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = $1900
σ is the population standard deviation = $200
For x = $1700
z = $1700 - $1900/$200
z = -1
Probability value from Z-Table:
P(x= 1700) = 0.15866
For x = $2100
z = $2100 - $1900/$200
= 1
Probability value from Z-Table:
P(x = 2100) = 0.84134
The probabilty of the population that has a rent price between $1700 and $2100
P(x = 2100) - P(x = 1700)
0.84134 - 0.15866
= 0.68268
Converting to percentage
= 0.68268 × 100%
= 68.268%
The percentage of the population that has a rent price between $1700 and $2100 is 68.268%
So Deborah found 1/4 of the students had a cell phone and so what is left I think it will be this 4:1
