Answer:
m>3 or m<-5
Step-by-step explanation:
First simplify -3m-1 < -10:
-3m < -9
m > 3 (switch direction of sign when dividing by negative number)
Then simplify -4+2m<-14:
2m<-10
m<-5
m>3 or m<-5
560+ 147= 707
14(40)= 560
14+ 14(1/2)=21
21(7)= 147
(179.3)/(61.5) *10 time both sides by 10 to get rid of the decimal
1793/615
615*2= 1230 615 goes two times into 1793 before exceeding
1793-1230=563 remainder which is less than 615 hence will give a decimal when divided by 615
563/615= 0.9
2+0.9 = 2.9 is the answer
for a longer decimal you can easily use a calculator
Answer:

Step-by-step explanation:

Formula for standard deviation sample calculation is:
SD = sqrt (( ∑( x - m)²) / ( n - 1 )),
where x stays for each value in the data set, m stays for mean of all values in the data set, and n stays for the number of values in the data set.
For example: Find the sample standard deviation for the set of numbers: 10, 11, 11, 12, 12.
First we will find mean of all avlues: m = ( 10 + 11 + 11 + 12 +12 ) / 5 = 11.2
SD = sqrt (( 1.2² + 0.2² + 0.2² + 0.8² + 0.8² ) / ( 5 - 1 ))=
= sqrt ( 2.8 / 4 ) = √0.7 = 0.837
