Carlos is half as old as Andre Andre is 15 years older than Carlos how old is Andre
Leokris [45]

Answer:

30 years old

Step-by-step explanation:

Let the two ages be A and C.

Then C = (1/2)A, and A = C + 15.

Substitute C + 15 for A in C = (1/2)A:

C = (1/2)(C + 15), or   2C = C + 15.

Then C = 15, and A = C + 15 becomes  A = 15 + 15, or  A = 30.

PLZ HELP! Use technology or a z-score table to answer the question.
Rashid [163]

Answer:

the answer would be A, or 5.3%

Step-by-step explanation:

you start by finding the z-score of 200, so 200-144.05 = 55.95/34.52 = 1.62 (rounded to the nearest ) Then you use a z-score table to find the probability that a customer will spend less than 200 dollars and subtract the decimal probability from one. then you convert the decimal probability to a percent and get 5.3%.

If it's possible to tell, decide if a and b are positive or negative: a-3&gt;b-3 and b&gt;4
Svetllana [295]

Answer:

a and b are positive

Step-by-step explanation:

We are given that

a-3>b-3

b>4

We have to find that a and b are positive or negative.

We have

b>4

It means b is positive and greater than 4.

a-3>b-3

Adding 3 on both sides

a-3+3>b-3+3

a>b>4

\implies a>4

Hence, a is positive and greater than 4.

Therefore, a and b are positive
