Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were all

Sergio039 [100]

Let events
A=Nathan has allergy
~A=Nathan does not have allergy
T=Nathan tests positive
~T=Nathan does not test positive

We are given
P(A)=0.75 [ probability that Nathan is allergic ]
P(T|A)=0.98 [probability of testing positive given Nathan is allergic to Penicillin]

We want to calculate probability that Nathan is allergic AND tests positive
P(T n A)

From definition of conditional probability,
P(T|A)=P(T n A)/P(A)
substitute known values,
0.98 = P(T n A) / 0.75
solving for P(T n A)
P(T n A) = 0.75*0.98 = 0.735

Hope this helps!!

a person bought 8 items at a market and received $8 in change. if each item was priced at $4, how much did the person give the v

mariarad [96]

If a person bought 8 items and each item was priced at $4, that means the total amount spent was $32.

$(8)(4)=32$

The person received 8 dollars in change. This means that the person payed 8 dollars more than what they spent. Well, we just found out how much they spent, so we can find out how much money the person gave the vendor.

Let p = amount of money paid by the person.

$32+8=p$

$p=40$

The person gave the vendor $40.

If the marked price of an article is Rs.x, discount amount is

bezimeni [28]

Answer:

The marked price of an article is Rs. x, and selling price is Rs. y

Price difference = Rs. (x−y)

Now, on Rs. x, there is a discount of Rs. (x−y)

Thus, on Rs. 100, there will be a discount of Rs.

(x−y)

×100%.

Nostrana [21]

Answer:

<h2>$ 22200 in higher yielding bank and $ 44400 in lower yielding bank</h2>

Step-by-step explanation:

Jolene invests in two bank accounts. The first account gives a 4% interest per year and the second bank gives a 10% interest rate per year.

She puts twice as much in the lower yielding bank account. Let us denote the amount put in high yielding bank account by $x$ . Lower yielding bank account will have $2x$ .
