Can someone please answer this!
Rus_ich [418]

Answer:

Answer is 49

Step-by-step explanation:

Add all the ratios up you get 21 so then you divide 147 by 21 thus giving you 1 ratio = 7 respectively, and we know the ratio of the red is 7 because it's stated red, blue, and green -> 7,6,8. So then 7 * 7 = 49. And to confirm you can do (7*7)+(6*7)+(8*7) which should equal 147

The two-way table is attached.

We know that 63 people took the survey, and 22 of them were left-handed.  This means that 63-22=41 of them are right handed.

Out of the 63 total, 37 are left brain dominant; this means that 63-37=26 are right brain dominant.

Of the 26 that are right brain dominant, 21 are right handed; this means 26-21=5 are left handed.

Of the 22 left-handed people, 5 are right brain dominant; this means 22-5 = 17 are left brain dominant.

Of the 37 left brain dominant people, 17 are left handed; this means 37-17=20 are right handed.

How can you show that two objects are proportional with an equation
masha68 [24]
For an equation to be proportional, it must have no y intercept, and it must have a slope. So, 
<span>y=4x+4  This equation isn't proportional because it has a y-intercept (+4)
y=4x+2  </span>This equation isn't proportional because it has a y-intercept (+2)
y=4x      This equation is proportional because it has no y-intercept, and a                     slope.
