Answer:
im confused on that question too but here is the a pic for u
Step-by-step explanation:
Answer: 
Step-by-step explanation:
It is important to remember that:
- Integers contains the positive numbers (+), negative numbers (-) and zero.
- The numbers greater than zero are Positive Integers.
- The numbers less than zero are Negative integers.
- An integer and its opposite have the same distance from zero, but they are located on opposite sides of the number line.
In this case we know that 
is a Positive Integer, therefore, based on the information mentioned before, we can say that its negative (or its opposite) is:
Answer:
73
Step-by-step explanation:
647 - 574
1.) subtract 7 -4 and you get 3 in the ones place.
2.) next you have to do 4 -7 and you can't do that so you take one from the hundreds place and turn the 6 into a 5.
3. make the 4 a 14 and then subtract 14-7 and you get 7 in the tens place
4.) you are then left with 5-5 in the hundreds place which is 0 so your answer is 73
Answer:
10m
Step-by-step explanation:
You use Work done=Force × Distance
So therefore 1000=100×D
Therefore D=10m
Answer: 90% confidence interval is; ( - 0.0516, 0.3752 )
Step-by-step explanation:
Given the data in the question;
n1 = 72, n2 = 17
P1 = 54 / 72 = 0.75
P2 = 10 / 17 = 0.5882
so
P_good = 0.75
P_bad = 0.5882
standard ERRROR will be;
SE = √[(0.75×(1-0.75)/72) + (0.5882×(1-0.5882)/17)]
SE = √( 0.002604 + 0.01424)
SE = 0.12978
given confidence interval = 90%
significance level a = (1 - 90/100) = 0.1, |Z( 0.1/2=0.05)| = 1.645 { from standard normal table}
so
93% CI is;
(0.75 - 0.5882) - 1.645×0.12978 <P_good - P_bad< (0.75 - 0.5882) + 1.645×0.12978
⇒0.1618 - 0.2134 <P_good - P_bad< 0.1618 + 0.2134
⇒ - 0.0516 <P_good - P_bad< 0.3752
Therefore 90% confidence interval is; ( - 0.0516, 0.3752 )
