Step-by-step explanation:
from the word Bi "meaning two"
Bivariate data are two different variables obtained from the same population element. Bivariate data are used if the sampled data cannot be graphically displayed using a single variable.
To form a bivariate data, there are three combinations of variable
1. Both variables are qualitative i.e attribute in nature
2. Both variables are quantitative i.e numerical
3. One of them is qualitative whilee the other is quantitative
Qualitative data are data that are measure of type which could represent a name, colour,symbol. traits or characteristics
Quantitative data are data that can be counted, measured and expressed using numbers/
Answer:
-3
Step-by-step explanation:
Since the - in -7 and the subtraction sign - are the same, you have to group them so now it is + (positive). -10 + 7 = -3
☆Open the brackets by multiplying out
120 - 84 + 9g = 2g + 5g + 36
☆Collect like terms
9g - 2g - 5g = 36 -120 +84
2g = 0
☆Divide by 2 to find x
g = 0
Answer: im on this one too
Step-by-step explanation:
Answer:13.5 inches
Step-by-step explanation:
Here, the volume of a right circular cone varies jointly as the altitude and the square of the radius of the base
So our equation for volume becomes
V = c*h*r^2
where 'h' is altitude and 'r' is radius of base and 'c' is constant
Putting the value of V,h,r,
we get,
154 = c*12*3.5*3.5
c = 22/21
Now we have volume = 77 cu and radius of the base =7/3, so putting the values we get,
77 = 22/21*h*7/3*7/3
or, h= 13.5
Hope it helps!!!
