Liz earns a salary of $2,000 per month, plus a commission of 8% of her sales. She wants to earn at least $2,500 this month. Ente

andrezito [222]

Answer: $2000 + 0.08s ≥ $2500

Step-by-step explanation:

The expression that will be used to calculate the earnings of Liz will be:

= b + (c × s)

Where:

b = base salary = $2,000

c = commission rate = 8% = 8/100 = 0.08

s = the sales that the commission rate will be applied against.

The inequality to find amounts of sales that will meet Liz goal will be:

= b + (c × s)

= $2000 + (0.08 × s) ≥ $2500

= $2000 + 0.08s ≥ $2500

On a six-question multiple-choice test there are five possible answers for each question, of which one is correct and four are i

gizmo_the_mogwai [7]

Answer:

Step-by-step explanation:

given that on a six-question multiple-choice test there are five possible answers for each question, of which one is correct and four are incorrect

By mere guessing probability for choosing correct answer = p = 0.2

also each question is independent of the other

Hence if X is the number of correct questions then

X is binomial with p = 0.2 and n = 6

a) being correct on three questions,

= $P(X=3) = 0.08192$

(b) being correct on four questions,

= $P(X=4) = 0.01536$

= $P(x=6) = 0.000064$
