Answer:
170.72
Step-by-step explanation:
to find the mean, we must add al the numbers and divide it by n
that is,
164,175,178,166,167,145,176,150,174,162,180,156,173,158,182,184,160,172,186,168,195,169,171,187,170 we have to add al these numbers and divide it by 25
sum- 4628 divided by 25
=170.72
Note that
and
Then their LCM is .
x = 52
y = 38
Angle x is supplementary to a 128º angle.
Supplementary angles add to 180
x+128 = 180
Subtract 128 from each side
x+128-128 = 180-128
x =52
Angle x and y are complementary.
Complementary angles add to 90
x+y =90
52+y =90
Subtract 52 from each side
52-52 +y = 90-52
Answer: domain is all real numbers and range is all real numbers greater than or equal to -2
Answer: 1.1%
To get a percentage you want to divide the ending number by the base number
73 / 68 = 1.07
It says to round to the neartest tenth, when rounding if the number is 5 or above you round up, if under 5 your number stays the same
7 is higher than 5 so we round up
1.1%
