Jerry earns a base salary of 350 per week plus an 8% commission on all sales at his job. Which inequality shows the minimum amou

inysia [295]

Answer:

Step-by-step explanation:

8% in decimal form is written out as 0.08, so right away the answer is either C or D.

Then if you have "s" = 1875, you would get:

350 + (0.08 × 1875) = 500

That would mean any number greater than 1875 will give you a total more than 500.

Therefore the answer is D.

A jar contains 38 red marbles numbered 1 to 38 and 38 blue marbles numbered 1 to 38 a marble is drawn at random from the jar

liq [111]

Answer:

$P(Red) = 0.50$ '

$P(Odd) = 0.50\\$

Step-by-step explanation:

Given

$Red = 38$

$Blue = 38$

Required (Missing part of the question)

(a) The marble is red. (b) The marble is odd-numbered

Solving (a): Probability of Red.

This is calculated as:

$P(Red) = \frac{Red}{Total}$

$P(Red) = \frac{38}{38+38}$

$P(Red) = \frac{38}{76}$

$P(Red) = 0.50$

Solving (b): Probability of Odd

Since each marble type is numbered 1 to 38, then half of it are odd.

i.e. 19 odd numbered red marbles and 19 odd numbered blue marbles.

So, the probability of odd is:

$P(Odd) = \frac{Odd}{Total}$

$P(Odd) = \frac{19+19}{38+38}$

$P(Odd) = \frac{38}{76}$

$P(Odd) = 0.50\\$
