Answer:
399 minutes a month
Step-by-step explanation:
As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.
The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).
The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.
Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.
Answer:
y=-3/2x-7
Step-by-step explanation:
I am going to assume that the question is asking how many buttons are in each of the 8 groups.
To find out how many buttons are in each of the 8 groups, we simply need to divide the amount of groups by the total amount of buttons.
3250 / 8 = 406.25
That is unlikely the answer, since buttons are hard to divide into quarters.
**************
This is the more likely solution. There are 8 groups of buttons, with 3250 buttons in each group. To find the total amount of buttons, we just need to multiply the number of groups of buttons there are by the amount of buttons there are in each group.
8 * 3250 = 26000
There are 26,000 buttons total.
Hope that helped =)

As per given , we have
p= 0.457
n= 1033
Margin of error for 99% confidence : E= 4%=0.04
Confidence interval : 
i.e. 
99% confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt. = (0.417, 0.497)
Interpretation : We are 99% sure that the true population proportion of registered voters who are in favor of raising income taxes to pay down the national debt lies in interval (0.417, 0.497).
