3 out of 12 because all together it equals 12 marbles
Answer:
c. neither significantly low nor significantly high.
Step-by-step explanation:
We have been given that 1700 births are randomly selected and 857 of the births are girls. We are asked to choose the correct option about number of girls using subjective judgement.
We could expect that there would be 850 boys and 850 girls on average among 1700 births.
In our given scenario there are 857 girls, so there would be 843 boys. 857 girls compared to 850 girls are close.
Now probability of choosing 857 girls or more from 1700 births is approximately 0.5041 or 50%, therefore, the outcome is neither significantly low nor significantly high.
Find the surface area of a cube by squaring the length of one side and multiplying the result by 6.
Example: The surface area of a cube with side length 3 is "6 x (3 x 3) = 54".

Answer:
A. y=x-3
B.y=x-3
Step-by-step explanation:
Okay so essentially, the first thing you need to do is find the slope and y intercept for each equation. To find the slope, I like to look at the two points and divide the rise (How much it goes up or down) by the run (How much it moves left or right). For A the rise is 6 and the run is 4, so the slope is 6/4 or 3/2. To find the equation for A, you also need the y-intercept which is just the y value (how high up or down) it is when it crosses the y axis. In graph a, this is at -3. Because the equation of a line is y=mx+b (m being slope and b being y intercept), we know the equation for a is y=x-3. We can do the same thing for B. The rise is -3 and the run is 4, so the slope is -3/4. The y value when x is equal to zero is 2, so that is the y intercept. The equation is y=x-3
