Answer:
2.576
Step-by-step explanation:
Given :
Confidence level (α) = 99%
Z(1 - α)/2 = Z(1 - 99%)/2
Z1%/2 = Z1%/ 2
Z0.5% = Z0.005
Z(0.99 + 0.005) = Z0.995
Using the Z distribution table ; locate the z value for the proportion 0.995 ; this corresponds to approximately 2.57
Similarly, using the Invnorm calculator function :
Invnorm(0.995) gives a Zscore of :
2.576
Answer:
30
Step-by-step explanation:
Ratio of two numbers = 2 : 5
The numbers are 2x , 5x
Larger number = 75
5x = 75
x = 75 ÷ 5
x = 15
Smaller number = 2x
= 2*15
= 30
Answer:
Hey there!
Your answer would be y=-2/3x+2
We are given 2x+3y=6, and want to turn that into a slope-intercept equation (y=mx+b, where m is the slope and b is the y intercept)
Start by subtracting 2x on both sides: 3y=6-2x
Rearrange to get the x term before the 6: 3y=-2x+6
Divide by 3 to get your answer: y=-2/3x+2
Y^24 isn't a cube, the closest number is 27
Answer:
17.5% per annum
Step-by-step explanation:
<u>Given:</u>
Money invested = $20,000 at the age of 20 years.
Money expected to be $500,000 at the age of 40.
Time = 40 - 20 = 20 years
<em>Interest is compounded annually.</em>
<u>To find:</u>
Rate of growth = ?
<u>Solution:</u>
First of all, let us have a look at the formula for compound interest.
Where A is the amount after T years compounding at a rate of R% per annum. P is the principal amount.
Here, We are given:
P = $20,000
A = $500,000
T = 20 years
R = ?
Putting all the values in the formula:
So, the correct answer is <em>17.5% </em>per annum and compounding annually.
