Answer:
The proportion of disks which are defective is 0.16.
Step-by-step explanation:
The proportion of defective disks is the number of defective disks in the sample divided by the size of the sample.
In this question:
2346 disks.
1971 not defective, so 2346 - 1971 = 375 defective.
[tex]p = \frac{375}{2346} = 0.16[/tex]
The proportion of disks which are defective is 0.16.

Trever invested $10,000 in an account that earns 8.5%
interest that is compounded monthly.
(a) Write an exponential model for the balance of the
account.
(b) Determine the amount of money in the account
after 15 years.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Trever invested $10,000 in an account that earns 8.5% interest that is compounded monthly.
First, we need to calculate the monthly interest rate:
i= 0.085 / 12= 0.00708
Now, to calculate the future value of the investment, we need to use the following formula:
FV= PV*(1+i)^n
PV= initial investment
i= interest rate
n= number of periods
In this case:
FV= 10,000*(1.00708^n)
Finally, for 15 years:
n= 15*12= 180 months
FV= 10,000*(1.00708^180)
FV= $35,605.31

Wayne plans to make a nut mixture in the weight ratio 1:2:5, containing cashows, almonds, and pecans, respectively. Which situation represents the function f() = 2p?
O the number of pounds of almonds Wayne needs, if he plans to use p pounds of cashews
O the number of pounds of cashews Wayne needs, if he plans to use p pounds of almonds
O the number of pounds of almonds Wayne needs, if he plans to use p pounds of pecans
O the number of pounds of pecans Wayne needs, if he plans to use p pounds of almonds
Answer:
the number of pounds of cashews Wayne needs, if he plans to use p pounds of almonds
Step-by-step explanation:
Ration of Almonds:cashows = 1:2
Almonds/cashows = 1/2
2Almonds = cashows
f() = 2p <--> cashows = 2Almonds
As a result, the function represents the number of pounds of cashews Wayne needs, if he plans to use p pounds of almonds
3(6x)-8x = -2+5 (2x+1)
Answer:
x = 3
Step-by-step explanation:
So you will distribute the number beside the ( )
so the equation be looking like :
18x - 8x = 10x + 5 - 2
now combine like terms
18x - 8x = 10x
5 - 2 = 3
10x = 10x +3
now subtract 10x to the other side they cross off
leaving x = 3
and so that's your answer
hope this helps

If f(x)=3x-1 and g(x)=x2+2 what is f[g(x)]
Answer:
Value of f[g(x)] = 3x² + 5
Step-by-step explanation:
Given:
f(x) = 3x - 1
g(x) = x² + 2
Find:
Value of f[g(x)]
Computation:
f(x) = 3x - 1
g(x) = x² + 2
So,
f[g(x)] = 3(x² + 2) - 1
f[g(x)] = 3x² + 6 - 1
Value of f[g(x)] = 3x² + 5

How was Franklin D. Roosevelt a lasting impact even on today's society
Answer:
Franklin Delano Roosevelt, often referred to by his initials FDR, was an American politician who served as the 32nd president of the United States from 1933 until his death in 1945. A member of the Democratic Party, he won a record four presidential elections and became a central figure in world events during the first half of the 20th century. Roosevelt directed the federal government during most of the Great Depression, implementing his New Deal domestic agenda in response to the worst economic crisis in U.S. history. As a dominant leader of his party, he built the New Deal Coalition, which defined modern liberalism in the United States throughout the middle third of the 20th century. His third and fourth terms were dominated by World War II, which ended shortly after he died in office.
Step-by-step explanation:
to this ‘Great Man Theory’ it can be said that Franklin Delano Roosevelt upheld his victorious and highly regarded government through means of social, economic and political reforms, as well as ambitious personal and strategic decisions that have successfully remained influential to American society today and maintained his image as a prominent historic leader.

order the numbers from least to greatest
0.222
0.18
0.1
0.24
0.21
Answer:
0.1, 0.18, 0.21, 0.222, 0.24
Explanation:
look at the first number:
between 0.1 and 0.18, 0.1 is smaller therfore it is the least
next to that would be 0.18
next, 0.21, 0.222, and 0.24 all has the same first number so take a look at the second number:
0.21 would be the third number since the second number is 1, which is the smaller number out of 3
the 4th number would be 0.222 because 0.22 is less than 0.24
lastly, the greatest or largest number would 0.24

Functions:
In image 1: Evaluate the functions
In image 2: Given the functions, find their inverse, if possible and if not possible, redefine Domain or Range
Answer:
Image 11. x = 4
f(4) = (- 3*4 + 1) / 6 = -11/62. x = -2/3
f(-2/3) = -3*(-2/3) + 10 = 2 + 10 = 123. x = -5
f(-5) = [tex]\sqrt{-(-5)/20}[/tex] = [tex]\sqrt{5/20}[/tex] = [tex]\sqrt{1/4}[/tex] = 1/2Image 2To work out the inverse, substitute f(x) with x and x with y, then solve for y. The new function is the inverse of the given.1. f(x) = 5x + 3
x = 5y + 3 ⇒ 5y = x - 3 ⇒ y = (x - 3)/5f⁻¹(x) = (x - 3)/52. f(x) = 4/5x
x = 4/5y ⇒ y = 5/4xf⁻¹(x) = 5/4x3. f(x) = (2x + 7)/4
x = (2y + 7)/4 ⇒ 2y + 7 = 4x ⇒ 2y = 4x - 7 ⇒ y = 2x - 3.5f⁻¹(x) = 2x - 3.54. f(x) = (2x + 7) /(x + 3) = 2 + 1/(x + 3)
x = 2 + 1/(y + 3) ⇒ x - 2 = 1/(y + 3) ⇒ y + 3 = 1/(x - 2) ⇒ y = (1 - 3x + 6)/(x - 2) ⇒ y = (7 - 3x)/(x - 2)f⁻¹(x) = (7 - 3x)/(x - 2)5. f(x) = [tex]\sqrt{x - 4}[/tex]
x = [tex]\sqrt{y - 4}[/tex] ⇒ x² = y - 4 ⇒ y = x² + 4f⁻¹(x) = x² + 4A baker uses 24 cups of flour and 28 cups of water for a recipe. The flour-to-water ratio 24:28 How much water does the baker need if he uses only 6 cups of flour?
Answer: 7
Step-by-step explanation: So 24:28 is equal to 6:? so if we divide 24 by 6 we get 4. So 28 divided by 4 is 7. 6:7 is equal to 24:28.

PLEASE HELP AGAIN!! Max deposited $4,008 in a savings account with simple interest. Four years later, he had earned $641.28 in interest. What was the interest rate?
Answer:
4%
Step-by-step explanation:
For simple interest, the equation is I = PRT, where I is the interest, P is the principal/amount invested, R is the rate as a decimal, not percentage, and T is time in years.
641.28 = (4008)(r)(4)
641.28 = 16,032r
r = 0.04 = 4%
