Answer:When you multiply a negative number to a positive number, your answer is a negative number. It doesn't matter which order the positive and negative numbers are in that you are multiplying, the answer is always a negative number.
Step-by-step explanation:
It would be 7.80 , just add 6.10 +1.7 hope this helps
Answer:
A
Step-by-step explanation:
The margin of error of a given statistic is an amount that is allowed for in case of miscalculation or change of circumstances.
It is usually the radius or half of the width of the confidence interval of that statistic.
Given that a<span>
survey of the students in Lance’s school found that 58% of the
respondents want the school year lengthened, while 42% think it should
remain the same. The margin of error of the survey is ±10%.
This means that 58% </span><span>± 10% of the </span>respondents want the school year lengthened, while 42% <span><span>± 10% think it should
remain the same.</span>
Thus, from 48% to 68% </span><span><span>of the respondents want the school year lengthened, while from 32% to 52% <span>think it should
remain the same.</span> </span>
Therefore, according to
the survey data, at least 32% of students want the duration of the school
year to remain unchanged, and at least 48% want the school year to be
lengthened.</span>
<span>every number is divisible by 1 (Identity property)
A number is divisible by 2 if it is even (ends in 0,2,4,6,or 8)
A number is divisible by 3 if the sum of the digits in the number is divisible by 3.
A number is divisible by 4 if the last two digits are divisible by 4
A number is divisible by 5 if it ends in a 5 or a 0.
A number is divisible by 6 if it is divisible by 2 and 3 (use both those rules.)
A number is divisible by 9 if the sum of its digits is divisible by 9.
A number is divisible by 10 if it ends in a 0.
So by these rules
The sum of the digits are 8 + 0 = 8 so it is not divisible by 3 or 9.
1, 80
2, 20
4, 20
5, 16
10, 8
have a great day!
