Answer:n = 209

Step-by-step explanation:

6/11 = 114/n

Find the LCM of the expression

LCM = 11n

Multiply both sides of the equation by the LCM

11n x 6/11 = 11n x 114/n

6n = 1254

n = 1254/6

n = 209

The probability that a car has a certain factory defect is 825. The probability that a car has a certain factory defect and need

ipn [44]

Answer:

90.91% probability that a car needs an oil change given that it has a certain factory defect

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem, we have that:

Event A: having a factory defect.

Event B: needing an oil change.

The probability that a car has a certain factory defect is 825.

So $P(A) = 0.825$

The probability that a car has a certain factory defect and needs an oil change is 750.

So $P(A \cap B) = 0.75$

What is the probability that a car needs an oil change given that it has a certain factory defect

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.75}{0.825} = 0.9091$

90.91% probability that a car needs an oil change given that it has a certain factory defect

here's the equation: x+x+(x+12)+ 1/2(x+12) =81

combine like terms

(x+x+x+1/2x) + (12+6) = 81

simplify

7/2x +18=

subtract 18 from both sides.

7/2x=63

multiply by reciprocal (aka 2/7)

x=18

18+12=30 so celia gave 30.

Hope this helps!

A baker’s dozen includes 13 rolls for the price of a dozen rolls. How much money is saved by buying a baker’s dozen instead of 1

KatRina [158]

Answer:

$0.60

Step-by-step explanation:

If you purchase 6 rolls, you pay $3.60

Each roll is $0.60.

If you purchase 13 individual rolls, you pay

13 x 0.6 = $7.80

But if you purchase the Baker's dozen, you pay only $7.20, so you save $0.60

7.80 - 7.20 = 0.60

Hope this helps! :)
