Answer:
A general line can be represented as , y= m x + c
And general equation of circle is , ax²+by²+2 g x +2 f y +c=0
Now there are following possibilities
1. A line and circle have no common point of intersection, that is no solution.
2. A line may be a tangent to a circle, that is one common point, one solution.
3. A line may intersect a circle maximum at two points, that is 2 solution.

Answer:
H. 552
Step-by-step explanation:
Circle graph information:
- Milk and eggs = x%
- Fruits and vegetables = 38%
- Cereals = 10%
- Meat and fish = 10%
- Sugar = 8%
- Fats and oils = 4%
Total consumption = 1840 pounds per person
First, calculate the percentage of milk and eggs (the value of x).
Total percentages = 100%
⇒ x + 38 + 10 + 10 + 8 + 4 = 100
⇒ x + 70 = 100
⇒ x = 30
Therefore, 30% of food consumption is milk and eggs.
To calculate the number of pounds of milk and eggs the average American consumes each year, simply find 30% of the total consumption:
= 30% of 1840
= 30% × 1840

= 552
Therefore, the average American consumes 552 pounds of milk and eggs each year.
The second survey is more believable because there is randomness in the second rather than the first survey. Since the second company surveyed in all interest levels while the first company only surveyed their best customers. Random sampling like what the second company did helps produce representative samples by removing voluntary response bias and undercover age bias.
Answer:
4
Step-by-step explanation:
4 is way off of the other numbers.
Answer:
keiko- x
imelda- x+ 36
Sarah- x- 38
Step-by-step explanation:
- keiko is x since we have not been given his number of boxes.
- because imelda's number of boxes was 36 <em>more </em><em>than </em>keiko's, you will add the x which is for keiko and 36 for imelda(x+36).
- and sarah's number of boxes will be x-36 because we have been told her number of boxes is 38 <em>fewer </em><em>than </em> keiko's.
