We have been given that red, green, and white jellybeans are combined in a ratio of 5:4:3 respectively. We are asked to find out the ratio of green jelly beans to the total number of jelly beans.
In order to find out the ratio of green jelly beans to the total number of jelly beans we have to find out the total number of jelly beans.

Now we can find out out our desirable ratio by substituting our finding in the ratio.

Therefore, ratio of green jelly beans with respect to all jelly beans is 1:3.
Answer:
Point B is 4 units to the right and 2 units down
Step-by-step explanation:
Since our <em>x</em> is positive, we are going to the right of the x-axis (where positive values lay).
Since our <em>y</em> is negative, we are going down in the y-axis (where negative values lay).
Answer:
864.36 boxes
Step-by-step explanation:
In the question above, we are given the following values,
Confidence interval 95%
Since we know the confidence interval, we can find the score.
Z score = 1.96
σ , Standards deviation = 15mm
Margin of error = 1 mm
The formula to use to solve the above question is given as:
No of boxes =[ (z score × standard deviation)/ margin of error]²
No of boxes = [(1.96 × 15)/1]²
= 864.36 boxes
Based on the options above, we can round it up to 97 boxes.
