Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic to penicillin, Nathan had a 75% chance of having the same allergy. The doctor performed a skin test to see whether Nathan would react to it. The test is 98% accurate. What is the probability that Nathan is allergic to penicillin and the test predicts it?0.005

Probability that Nathan is allergic to pennicillin and the test predicts it
=Prob (Nathan is allergic)*P(test predicts it correct)
= 0.75(0.98)
=0.245

Answer:
10,070 and 10,047 pieces respectively
Step-by-step explanation:
In this question, we have 2 questions to answer.
Firstly, we are told that Jimmy has 530 pieces of paper and kit comes along to give him 18 times as much, we need to know how much he has now.
Since he was given 18 times as much, the amount given would be 18 * 530 = 9,540
The amount he has now would be 9,540 + 530 = 10,070 paper pieces
Secondly, Kim comes along to take 23 pieces away, we need to know how much pieces he has now. What to do is simply to
Subtract 23 from the previous pieces = 10,070 - 23 = 10,047 pieces of paper

Answer:
No he was not correct
Step-by-step explanation:
The Equation is 15 x + 6 = 14 x + 5
now By the steps brandon used let us solve the question
Step 1 : Add 14 negative x tile to both sides
which will make the equation
15x + 6 - 14x = 14x + 5 - 14 x
x + 6 = 5 .......(ii)
Step 2: Add 5 negative unit tiles to both sides of equation (ii)
which will make the equation
x +6 - 5 = 5 - 5
x + 1 = 0 .........(iii)
Step 3: x =1 is the answer
but from equation (iii) we see that
x + 1 =0
by adding -1 on both sides
x + 1 -1 = 0-1
x = -1
So the step three done by Brandon is wrong which explains he was not correct
Answer:
D.) Brandon is not correct because he should have added 6 negative unit tiles to isolate the variable in step 2.
