Answer:
Option 3 is correct.
Step-by-step explanation:
Given that Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic to penicillin, Nathan has 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.
we have to find the probability that Nathan is not allergic to penicillin and the test predicts it.
As, Nathan has a 75% chance of having the same allergy.
Hence, (100-75)%=25% chance of not having the same allergy.
Also the test predicts given
∴ Probability that Nathan is not allergic to penicillin and the test predicts it is =
=
Hence, Option 3 is correct.
A. 1/8
B. 1/2
C. 3/4
D. 1/4
I have more questions, so if you are willing to help with more than this then let me know and I will tell you the other questions!!
account, how much did Jane have in the account before she took out any money?
Step 1: If x represents the variable in the word problem above, explain what the variable should
represent.
Step 2: Write an equation to model the situation.
Step 3: Solve the equation and write your answer in sentence form. Show your work.
Answer:
x = the amount of money Jane had before she took out any
x - 135 = 650
x = 785
Step-by-step explanation:
Let x = the amount of money Jane had before she took out any
Set up the equation
x - 135 = 650
To solve the equation, we must add 135 on both sides to cancel the -135 on the left side of the equal sign.
x - 135 = 650
x = 785

15 is 2 1/2 of a number 6.
We need to find that 15 is 2 1/2 of what number.
In math, 'of' is also considered one of the arithmeticoperations which means multiplication within the brackets.
Let the unknown number be y.
Now, 2 1/2 of y=15
⇒5/2 ×y=15
⇒y=6
Therefore, 15 is 2 1/2 of 6.

▪ Answer:
n = 6
▪ Step-by-step explanation:
n × 2 1/2 = 15
n × 5/2 = 15
n × 5 = 30
n = 30 ÷ 5
n = 6
Answer:
a. C(x(h)) = 600h + 500
b. C(8) = 5,300
c. See below.
Step-by-step explanation:
a. C(x(h)) = C(30h) = 20(30h) + 500 = 600h + 500
b. C(8) = 600(8) + 500 = 5,300
c. 5,300 is the cost of making the number of shovels that can be made in 8 hours.
