Mathematics

10(z-3) = 3*8

10z-30 = 24

add 30 to both sides

10z = 54

divide both sides by 10

z = 5.4

but, if you meant z-  3/8, then

z = 27/40

Caroline's coffee shop sells a refill mug for $8.95. Each refill cost $1.50. Last month Sean spent $26.95 on a mug and refills.
Talja [164]
Alright! First you'd have to subtract the flat fee of the mug which is $8.95, then you'd have to divide by the rate which is $1.50. Your equation would be:
 (26.95 - 8.95) ÷ 1.50 = r 

Then you solve using your head.. lol.
(26.95 - 8.95) = 18.
(18 ÷ 1.50) = 12.
R = 12.

Hope this helps :).

Answer:

  • 35
  • 60
  • 91.7

Step-by-step explanation:

Horizontally the table values total the number in the first column.

  first row missing table value = 700 -665 = 35

  second row missing table values = 300 -240 = 60

__

The conditional probability formula applies.

  P(contains | positive) = P(contains & positive)/P(positive)

The probability associated with each table entry is that value divided by 1000. Then the numbers in the formula are ...

  P(contains | positive) = .665/(.665+.060) = .665/.725 ≈ 91.7%
