Answer:
The total amount of sugar used=2/3 of a cup
Step-by-step explanation:
The expression for the total amount of sugar used for the cake is;
T=S+O
where;
T=total amount of sugar
S=amount initially added
O=amount sprinkled over the top
This expression can also be written as;
Total amount of sugar=amount initially added+amount sprinkled over the top
In our case;
S=3/6 cup
O=1/6
replacing;
T=(3/6)+(1/6)=4/6 in its lowest form=2/3
The total amount of sugar used=2/3 of a cup
Answer:
1000
Step-by-step explanation:
Answer:
4 + 10i
Step-by-step explanation:
Expanding the bracket we have;
(7+3i)-(3-7i) = 7+3i-3+7i
(7+3i)-(3-7i) = 7+3i-3+7i = 7-3 + 3i + 7i= 4 + 10i
The answer is 11:100 and 11%
Answer: a) 453 b) 1537
Step-by-step explanation:
As per given , we have
Margin of error : E= 0.025
Critical value for 95% confidence interval :
a) The prior estimate of population proportion : p=0.08
Required sample size :-
The minimum sample size is 453 U.S. adults.
b) Since the prior estimate of population proportion is not available , so we take p= 0.5
Required sample size :-
The minimum sample size is 1537 U.S. adults.
