Answer:

C) 7:2

Step-by-step explanation:

To simplify a ratio, you just need to divide both sides by a common factor. In this case, the largest factor we can use is 6. So, let's divide both sides by 6:

(42/6):(12/6) = 7:2

Annette [7]

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
