Answer:
And the value for n rounded up would be n = 174
Step-by-step explanation:
We have the following info given:
previous estimation for the deviation
the margin of error desired
represent the confidence
The Margin of error is given by:
If we solve for the value of n we got:
For this problem we know that the confidence is 98% so then the significance level would be 
and the critical value would be:
And replacing we got:
And the value for n rounded up would be n = 174
The probability of getting a gym sock is 1/5
ANSWER:
7 / 80
8 3/4% expressed as a fraction is 7 / 80.
STEP-BY-STEP EXPLANATION:
Write 8 3/4% as a percentage with a decimal:
= 8.75%
Convert 8.75% to a fraction:
= 8.75% ÷ 100
= 8.75 / 100
Make the numerator a whole number by multiplying both the numerator and denominator by a 100:
= ( 8.75 × 100 ) / ( 100 × 100 )
= 875 / 10000
Divide the numerator and denominator in the fraction by their highest common factor ( HCF ):
HCF = 125
THEREFORE:
= ( 875 ÷ 125 ) / ( 10000 ÷ 125 )
= 7 / 80
On week 1, we started with a deposit of $200. Every week from that point on, we place a deposit of $55.
We know y is total amount of money (deposits) in the bank account.
We also know x represents the number of weeks.
On week 1, we would have $200 in the back account.
On week 2, we would have $200 + $55 or $255 in the bank account.
So, we could build an expression of 55(x - 1) + 200 which is equal to y.
So, y = 55(x - 1) + 200 is the answer.
The entire expression represents how many packages of pencils and pads of paper bought.
