The reason is because a negative * positive will always give a negative answer. Negative * negative and positive * positive will always have a positive answer.</span>
The answer is $1,170. The hospital bill is $1,500 less the $200 deductible which is $1,300. Sheldon will then pay for 10% of his portion so multiply $1,300 by 10% with is $130 and deduct it to $1,300 which gives you $1,170.
Answer:
The minimum sample size must be 1118 to have margin of error within one percentage point.
Step-by-step explanation:
We are given the following in the question:
Germination rate = 97% = 0.97
Margin of error = 1% = 0.01
We have to find the minimum sample size for a 95% confidence interval.
Formula for margin of error:
Putting values, we get,
Rounding off to integer,
Thus, the minimum sample size must be 1118 to have margin of error within one percentage point.
Step-by-step explanation:
We have
87+86+x
T is the total scores
n is number of tests done = 3
T/n is greater than or equal to 90
To get minimum test
T/n = 90
T = 90*n
= 90n
We solve for x
Remember n = 3
90x3 = 270
270 = 87+86+x
270 = 173+x
X = 270-173
X = 97
1.
X = 97
2.
You didn't add a value in your part b question. I used 80 though.
T/n < 80
T<80n
80x3= 240
T<240
87+86+x<240
X<240-173
X<67
X has to be less than 67 so we conclude that if x <=67 b grade will be lost.
form an idea of the amount, number, or value of; assess.
