1/6 x 5 is 5/6. You can do 1 x 5 which is 5. You don't need to multiply anything else. The answer is 5/6
Answer:
1. draw the parallelogram with side 20cm and 25cm respectively and also the diagonal as well.
2.Clearly it forms a triangle in the parallelogram with three known lengths of side.
3.Using the cosine rule : c^2=b^2+c^2 -2bc cos c to find the obtuse angle.
Step-by-step explanation:
Answer:
x3 + x2 - 1 = ( x 2 + 1) ( x + 1)
Step-by-step explanation:
Answer:
x-30
Step-by-step explanation:
Firstly, you do the first step, which is, 3x-18+4x+12-6x, then you continue simplifying it: 7x-18+12-6x.
Keep it on and on, the next step: x-18+12, add 18 and 12 together you get 30.
So the final answer is x-30
Answer:
mean = 254.6
median = 120
mode = 60
midrange = 958
For average data sets i prefer by finding the mean
Step-by-step explanation:
mean :
(98+120+493+206+73+102+183+870+76+60+60+112+147+1018+201) ÷ 15 = 254.6
median : 60 60 73 76 98 102 112 120 147 183 201 206 493 870 1018
find the middle number
= 120
mode :
number that is more than one
= 60
midrange :
highest number - smallest number
= 1018 - 60
= 958
