Answer:
45) Option A
- This is because every option has different modes and 70 is the mode and only one option has the mode as 70.
Hence, option A is correct.
46) Option B
- In all the options, the mode and medians are same hence we only have to find the mean which will help us to reach our correct option. The mean will be 40/17 = 2.35
Hence, option B is correct.
Answer: -8 degrees C.
Step-by-step explanation:
if you hear the what is the difference then you know you'll subtract:)
-20 - -12 = -8 degrees C.
Answer:
m = 
, b = - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Given
2x - 3y = 6 ( subtract 2x from both sides )
- 3y = - 2x + 6 ( divide all terms by - 3 )
y = x - 2 ← in slope- intercept form
with slope m = and y- intercept b = - 2
25% 6 divided by 24 will give you the percentage of copper in the bar
