In an examination, 40% of the candidates failed. The number candidates who failed was 160. How many candidates passed the examination?
Answers
Answer:
240 candidates
Step-by-step explanation:
40% candidates failed, i. e. out of every 100 candidates 40 failed.
40 failed ----------------------------- 100 total students
1 failed --------------------------------100/40 total students, given 160 failed therefore
160 failed ----------------------------(100/40) x 160 total students
Total students = (100/40) x 160 = 400
Number of candidates passed = (total candidates) - (total candidates failed)
= 400 - 160 = 240 candidates

What is annual interest rate?
An annual percentage rate is expressed as an interest rate. It calculates what percentage of the principal you'll pay each year by taking things such as monthly payments into account.
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Formula:
a(t) = p*2^(t/8)
given, t=24 , p =5000
a(24) = 5000*2^(24/8)
a(24) = 5000*2^3
a(24) = 5000*8
a(24) = $40,000
Thus, after 24 years, the amount will be $40,000

Solve for y.
3x + y = 3
y = [? ]x +
Answers
To solve for y, we need to isolate y on one side of the equation. We can do this by subtracting 3x from both sides of the equation:
3x + y - 3x = 3 - 3x
Simplifying the left side gives:
y = 3 - 3x
So the solution for y is:
y = -3x + 3
Therefore, y is equal to negative 3 times x plus 3.
-3x -3x
y = 3 - 3x

My checking account balance was $443 on February 1st and $872 on February 7th. Show the rate of change
Answers
Answer:
$61.29 per day.
Step-by-step explanation:
Checking account balance on February 1st: $443
Checking account balance on February 7th: $872
Difference in balances: $872 - $443 = $429
Number of days between February 1st and February 7th: 7 days
Rate of change = Difference in balances / Number of days
Rate of change = $429 / 7 days
To find the rate of change per day, divide the difference in balances by the number of days:
Rate of change = $429 / 7 days ≈ $61.29 per day
Therefore, the rate of change in your checking account balance during that period was approximately $61.29 per day.

If the sales tax is 7%, the price of the sunglasses is $61.6962
How to find the original price of the sunglasses before tax?She has $70 gift card for a department store.
She buys a new glasses with her gift card.
The gift card had a remaining balance of $3.66.
Therefore,
amount she bought the sunglasses with tax = 70 - 3.66 = $66.34
Hence,
Sales tax = 7 / 100 × 66.34 = $4.6438
Therefore,
The original price before tax = 66.34 - 4.6438 = $61.6962

Simplify (4^-2)^5 I have no clue what the answer is
Answers
Answer:
1/ 4^10
(ONE on top of a fraction. Four to the tenth power on the bottom of the fraction)
Step-by-step explanation:
When you have a power to a power the short cut (exponent rule) says to multiply the powers.
(4^-2)^5
Keep the same base, the 4
times -2 × 5, you get -10
so far after one step, you have
4^-10
Now usually, you would not leave an exponent negative. So to "fix" the negative exponent, you change it to positive by "pushing it" across the fraction bar.
4^-10
becomes:
1/ 4^10
This is a ONE on top of a fraction and FOUR to the tenth power on the bottom of the fraction.
The answer is:
1/4¹⁰
Work/explanation:
For this problem, I'm going to use the following exponent law:
\(\boxed{\!\!\boxed{\quad\sf{(x^m)^n=x^{mn}}\quad}\!\!}\)
So if we have "a power to a power", we multiply the powers.
And now that we're familiar with this property let's apply it.
\(\sf{(4^{-2})^5=4^{-2\times5}=4^{-10}}\)
Here the next exponent law comes into play.
______________________
\(\boxed{\!\!\boxed{\quad\sf{x^{-m}\:\:=\:\:\dfrac{1}{x^m}\quad}}\!\!}\)
So if we have a number raised to a negative power, we flop it over.
Let's apply the law to our problem now.
Our problem is:
\(\sf{4^{-10}\)
According to the law above, we should do the following:
\(\sf{4^{-10}=\dfrac{1}{4^{10}}}\)
It's better to leave the answer as it is.
Hence, the answer is 1/4¹⁰

What is the M.A.D. (mean absolute deviation) of the following data set?
8 9 9 7 8 6 9 8
Answers
The mean absolute deviation is 0.75
How to determine the mean absolute deviationTo calculate the mean absolute deviation (M.A.D.), you need to find the average of the absolute differences between each data point and the mean of the data set
From the information given, we have that the data set is;
8 9 9 7 8 6 9 8
Let's calculate the mean, we get;
Mean = (8 + 9 + 9 + 7 + 8 + 6 + 9 + 8) / 8
Mean = 64 / 8
Divide the values
Mean = 8
Let's determine the absolute difference, we get;
Absolute differences=
|8 - 8| = 0
|9 - 8| = 1
|9 - 8| = 1
|7 - 8| = 1
|8 - 8| = 0
|6 - 8| = 2
|9 - 8| = 1
|8 - 8| = 0
Find the mean of the absolute differences:
Average of absolute differences = (0 + 1 + 1 + 1 + 0 + 2 + 1 + 0) / 8
Absolute difference = 6 / 8 = 0.75
