Answer:
-30
Step-by-step explanation:
-|-30-(10-20)|-|5-(10-15)|=-|-30-(-10)|-|5-(-5)|
=-|-30+10|-|5+5|
=-|-20|-|10|
=-(20)-(10)
= -20-10
= -30
Let w = washer and d = dryer:
w + d = $770,
but w = d + 70, replace w with d+70
(d+70) + d = 770
2d + 70 =770
2d = 770 -70 = 700
and d=$350, then w=350+70 = 420
-5 because the denominator can’t equal zero
its actually 10 points
x^4 + 9x^3 + 15x^2 + 9x + 14
Split 15x^2 into 14x^2 + x^2
x^4 + 9x^3 + 14x^2 + x^2 + 9x + 14 factor as
x^2 [x^2 + 9x + 14 ] + 1 [ x^2 + 9x + 14 ] take out GCF
[ x^2 + 1 ] [ x^2 + 9x + 14 ]
[ x^2 + 1 ] [ x + 7 ] [ x + 2 ]

Answer:
(A) the specific number of siblings for each randomly selected student
Step-by-step explanation:
First Timothy wants to estimate the mean number of siblings for each student in his school
So he selected a random sample of 75 students, then recorded the number of siblings they have
He later find the mean.
You can see the mean was obtained from the selected group not all students in the school hence option D and E are not correct.
Option A clearly indicates a mean was obtained for the siblings that were from the randomly selected students.
