Answer with explanation:
A x% confidence interval interprets the percentage of certainty that a person can believe that the true population parameter.
It is also represented as Point estimate ± Margin of error
Confidence level is proportional to the Margin of error.
- As confidence level increases the error bound increases that makes the confidence interval broader.
- As confidence level decreases the error bound decreases , making the confidence interval narrower.
12 is the answer all u have to do is divide 2
Answer:
The inverse is 1/3x -2
Step-by-step explanation:
f (x) = 3x + 6
y = 3x+6
Exchange x and y
x = 3y+6
Subtract 6 from each side
x-6 = 3y+6-6
x-6 = 3y
Divide by 3
1/3x - 6/3 = y
1/3x -2 = y
The inverse is 1/3x -2
The number of squares of whole pita bread Min will have to cut up is;
<u><em>21 squares of whole pita bread</em></u>
- Since the triangle is isosceles, and has base of 4 cm with 2 equal sides of 6 cm, it means the height is 5.7 cm.
- Thus, area of triangle is;
A = ¹/₂ × 4 × 5.7
A = 11.4 cm²
- She will cut 3 pita triangles for every guest. This means that;
Area for each guest = 3 × 11.4 = 33.2 cm²
- There are 250 guests and so the total needed for the 250 guests is;
Total area = 250 × 33.2
Total area of pita bread = 8300 cm²
- The bread comes in 20 cm sides of a square shape.
Area of square = 20 × 20 = 400 cm²
- Number of squares of whole pita bread she will have to cut = 8300/400
⇒ 20.75 ≈ 21 squares of whole pita bread
