Given:
Total number of marbles in the bag = 150
There are 21 blue marbles for every 4 white marbles.
To find:
The number of blue marbles in the bag.
Solution:
Since, there are 21 blue marbles for every 4 white marbles, therefore the ratio of blue marble to white marbles is 21:4.
Let the number of blue marbles be 21x and white marbles be 4x.
Total number of marbles in the bag = 150
Divide both sides by 25.
Now,
Therefore, the number of blue marbles is 126.
9.89%
You can get this number by multiplying the two together.
Box-and-whisker plot
We are given the box-and-whisker plot that summarizes the magnitude of earthquakes.
The minimum value of the dataset is 2,5
The maximum value of the dataset is 8.5
The range is the difference:
Range = 8.5 - 2.5 = 6
Range = 6
Answer:y=15/4
Step-by-step explanation:
start with general form y = kx. substitute in the pair of values you know for x and y.
75/8 = k(5) multiply both sides by 1/5 to solve for k, getting
15/8 = k
So your equation is y = (15/8)x substitute 2 for x to find your new y.
y = (15/8)2
y = 15/4
Answer:
im not sure what is supposed to go into the first two boxes, but the correct y intercept is 48
Step-by-step explanation:
first you subtract 288x on both sides, leaving the equation at -4y= -288x-192. then you want to get y by itself so you divide both sides by -4. -288/-4=72; -192/4=48. so the equation you are left with is y= 72x+48. since the equation is now in slope intercept form, you can now identify the y intercept as 48. hope this helps :)
