● Answer:
8.995 cm
● Step-by-step explanation:
P = d + L/2
d = 3.5 cm
L/2 = 2pi×r/2
= pi×d/2
= 3.14×3.5/2
= 5.495 cm
P = 3.5cm + 5.495
= 8.995 cm
Step-by-step explanation:
the three rows above you may draw as the ratio table
1. C
2. A
3. A
i’m pretty sure for 1,2. 3 i’m a little iffy but i think it’s A bc “homogenizing”
B) The probability that both marbles are purple is 2.22%.
C) The probability that you pick at least one purple marble is 98%.
<h3><u>Probability</u></h3>
The question is incomplete, since the number of marbles of each color in the bag is missing: 3 blue, 5 green, and 2 purple marbles.
Now, to answer the questions, the following calculations must be done:
- B) 2/10 x 1/9 = X
- 0.2 x 0.11111 = X
- 0.022222 = X
- X x 100 = 2.22
- C) 100 - (2/9x9) = X
- 100 - 2 = X
- 98 = X
