r. Yi buys vegetables at a market. He purchases 6 pounds of potatoes, p, and 3 pounds of onions, n, for $18. Onions cost twice a
ad-work [718]

Answer:

  • The equation 2n = p should be 2p = n.
  • The actual cost of the onions is $3.00 per pound.
  • Potatoes cost $1.50 per pound.

Step-by-step explanation:

The wording "onions cost twice as much as potatoes" is understood to mean the cost per pound of onions (n) is equal to two times the cost per pound of potatoes (2p). Then the appropriate equation would be ...

  2p = n

Then the solution is ...

  6p +3(2p) = 18

  12p = 18

  p = 18/12 = 1.50

  n = 2p = 2(1.50) = 3.00

__

The equation should be 2p = n; onions cost $3.00 per pound; potatoes cost $1.50 per pound.

A health statistics agency in a certain country tracks the number of adults who have health insurance. Suppose according to the
Fynjy0 [20]

Answer:

a) 15.4% probability that a randomly selected person in this country is 65 or older

b) 0.023 = 2.3% probability that the person is 65 or older

Step-by-step explanation:

To solve b), i will use the Bayes Theorem.

Bayes Theorem:

Two events, A and B.

P(B|A) = \frac{P(B)*P(A|B)}{P(A)}

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

(a) What is the probability that a randomly selected person in this country is 65 or older?

22.7% of people in the county are under age 18

61.9% are ages 18–64

p% are 65 or older.

The sum of those is 100%. So

22.7 + 61.9 + p = 100

p = 100 - (22.7+61.9)

p = 15.4

15.4% probability that a randomly selected person in this country is 65 or older.

(b) Given that a person in this country is uninsured, what is the probability that the person is 65 or older?

Event A: Uninsured

Event B: 65 or older.

15.4% probability that a randomly selected person in this country is 65 or older.

This means that P(B) = 0.154

1.4% of those 65 and older do not have health insurance.

This means that P(A|B) = 0.014

Probability of not having insurance.

22.7% are under 18. Of those, 5.4% do not have insurance.

61.9% are aged 18-64. Of those, 12.8% do not have insurance.

15.4% are 65 or over. Of those, 1.4% do not have health insurance. So

P(A) = 0.227*0.054 + 0.619*0.128 + 0.154*0.014 = 0.093646

Then

P(B|A) = \frac{0.154*0.014}{0.093646} = 0.023

0.023 = 2.3% probability that the person is 65 or older

What is the batting average of 34 out of 99
Gekata [30.6K]
<span>Safarina has 34 out of 99 hits.
Find her battling average.
=>  34 hits
=> 99 hits in all
x = value of percentage
=> 34 = x * 99
=> 34 = 99x
Now, let’s divide both sides with 99
=> 34 / 99 = 99x / 99
=> 0.3434343 = x (0.343434… is a repeating decimals, so need to round off to the nearest hundreds)
=> 0.34 = 34/100
Thus, the percentage of Sarafina’s hit is 34%</span>
