Total mass = 8 kg
Mass of tool 1 = 4 kg
Mass of tool 2 = 2 kg
So,
Total mass = Mass of tool 1 + Mass of tool 2 + Mass of tool 3
=> 8 kg = 4 kg + 2 kg + Mass of tool 3
=> 8 kg = 6 kg + Mass of tool 3
=> 8 kg - 6 kg = Mass of tool 3
=> 2 kg = Mass of tool 3
Answer:
The answer is 166
Step-by-step explanation:
How you find the answer is easy, you just divide 3,000 by 18. So it will look like this: 3,000/18. Then, once you have that, put the equation into a calculator and you get 166.
Answer:
first question: c. x = 1
6. B. y = -2x - 8
Step-by-step explanation:
first question:
perpendicular means that when it intersects, it makes a right angle.
the equation y = 5 would be parallel to any of the answers with y = ___ because all of those would result in horizontal lines
either of the x = ___ would be perpendicular to y = 5
since it has to pass through the point (1,3) that means that the equation must be x = 1
the equation x = 1 passes through any point beginning with (1 , _)
6.
parallel means that the equations have the same slope. therefore, we can eliminate both A and C
using the given point (-2 , -4),we can plug into the y = mx + b format to solve
m = -2 x = -2 y = -4
-4 = (-2)(-2) + b --> -4 = 4 + b --> b = -8
finally, our equation comes out to be y = -2x - 8
D, 7-7 = 0
1-1 = 0
0 x 0 = 0
Answer:
Step-by-step explanation:
Pooled proportion
The hypothesis null would be
Alternate can be either not equal to or < or > according to need
Std error for difference of proportions
Hence test statistic = p difference/std error
= 
where p is given as above as combined proportion.
