Hi it is 7n I hope I was right
Answer:
D
Step-by-step explanation:
If 2 tangents are drawn to a circle from the same external point then they are congruent.
AG and AE are tangents to the circle from the same external point, thus
AG is congruent to AE
The probability of picking a red marble three times in a row with replacement is:
number of red marbles divided by total number of marbles cubed...
(6/10)^3=27/125
The above is the theoretical probability...
From the chart we see that three reds in a row happened twice in twenty-five trials so the experimental probability is:
2/25
The experimental probability about 0.14 less than theoretically expected...
C)
With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.
<h3>What is the surface area of a truncated prism?</h3>
The <em>surface</em> area of the <em>truncated</em> prism is the sum of the areas of its six faces, which are combinations of the areas of rectangles and <em>right</em> triangles. Then, we proceed to determine the <em>surface</em> area:
A = (12 cm) · (4 cm) + 2 · (3 cm) · (4 cm) + 2 · (12 cm) · (3 cm) + 2 · 0.5 · (12 cm) · (5 cm) + (5 cm) · (4 cm) + (13 cm) · (4 cm)
A = 48 cm² + 24 cm² + 72 cm² + 60 cm² + 20 cm² + 52 cm²
A = 276 cm²
With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.
