Answer:

0.24315

Step-by-step explanation:

Using the z score formula to solve this question

z = (x - μ) / σ,

Such that:

x = raw score

μ = population mean

σ = population standard deviation.

From the question:

x = 3000

μ = 3550

σ = 870

z = (3000 - 3550) / 870

z = -550/870

z = -0.6962

Using the z score table as well as probability calculator(as requested in the question to find the z score)

The probability of having less than 3000 is obtained as:

P(x<3000) = 0.24315

Which expression correctly represents “nine less than the quotient of a number and four, increased by three

Natasha2012 [34]

The required expression is $\frac{x}{4}-9+3$

Step-by-step explanation:

We need to identify the expression correctly represents “nine less than the quotient of a number and four, increased by three"

Solving:

Let the number is x

The quotient of number and four: $\frac{x}{4}$

nine less than the quotient of a number and four: $\frac{x}{4}-9$

Increased by 3 : $\frac{x}{4}-9+3$

So, nine less than the quotient of a number and four, increased by three is:

$\frac{x}{4}-9+3$

So, The required expression is $\frac{x}{4}-9+3$
