If 5 hotdogs and 15 hamburgers cost 29.50 and 10 hot dogs and 15 hamburgers cost 56.25. how much are the hot dogs and how much a
Orlov [11]

Answer:

Hotdog costs $5.35 each and hamburger costs $0.18 each

Step-by-step explanation:

The difference in price between the two is the cost of 5 hotdogs.

So, $56.25 - $29.50 = $26.50

I hotdog would cost $26.50/5 = $5.35

Substituting the cost of one hotdog,

10($5.35) + 15ham = $56.25

$53.50 + 15 ham = $56.25

15 ham = $56.25 - $53.50

15 ham = $2.75

So, 1 ham = $2.75/15

= $0.18

Two factories I and II produce phones for brand ABC. Factory I produces 60% of all ABC phones, and factory II produces 40%. 10%
denpristay [2]

Answer:

0.3721 or 37.21%

Step-by-step explanation:

P(I) = 0.60; P(II) = 0.40;

P(not defective I) = 0.90; P(not defective II) = 0.80

The probability that the phone came from factory II, given that is not defective, is determined by the probability of a phone from factory II not being defective divided by the probability of a phone not being defective.

P(II|not) = \frac{P(II)*P(not_{II})}{P(II)*P(not_{II})+P(I)*P(not_{I})}\\P(II|not) = \frac{0.40*0.80}{0.40*0.80+0.60*0.90}\\ P(II|not) =0.3721 = 37.21\%

The probability is 0.3721 or 37.21%.
