The mean is the average of the numbers. To obtain it, you add all the numbers together and divide by the number of numbers. So:
8+3+3+7+4= 25
25:5= 5
So the answer is: the mean is 5.
Answer:yes
Step-by-step explanation:
Answer:
4x-7
Step-by-step explanation:
Solve for x:
180 = 44 + 3x - 11 + 4x - 7
Combine like terms: 180 = 26 + 7x
Simplify: 154 = 7x
Simplify: 22 = x
Substitute: 3(22) - 11 = 55 and 4(22) - 7 = 81
Create inequality: 44 < 55 < 81
Lineare means it is in a straight line aka highest exponent on any placeholder is 1
y=2^2-4
y^1=2^2-4
yep
answer is this is linear
If angle BCD measures 70° then so does angle DBC (because you have formed an isoceles triangle inside the larger ΔABC and the two legs are equal so the two angles have to be equal. So we have a two 70° angles which leaves 40° for the 3rd angle, which is ∠BDC.
Since ∠BDC and ∠ADB are supplementary (180°) - that leaves 140° for ∠ADB and is our answer
