Answer:
x + y = 83
Step-by-step explanation:
When it says opposite angles are supplementary and yo use A as a reference point it means
supplementary means they add to 180
so
A + C = 180
so
2x + 4 + 2y + 10 = 180
now simplify
2x + 2y + 14 = 180
- 14 -14
2x + 2y = 166
/2 /2
x + y = 83
The first 2 represents 200,000
The second 2 represents 20,000
The third 2 represents 2,000
The fourth 2 represents 200
The fifth 2 represents 20
The last 2 represents 2
Answer:
C- Total pens produced that week
D- 13000
Step-by-step explanation:
C- If 3/4 of the pens are red. 3/4 of the pens is equall to 39,000 therfore 3/4(pens)=39,000
D- 3/4 of the pens are red and there are 39,000 pens, you divide these pens by 3 and the answer you get is the green pens. 39,000/3=13,000
Not a function pretty sure
For normal distribution 95% lie in the range mean-2*standard deviation for lower bound and mean+2*standard deviation for upper bound.
Upper bound is 78+2*6=78+12=90
Lower bound is 78-2*6=78-12=66
B. 66 and 90
