Answer:
2102.13 mm^2
Attached is a completed image of the question
Step-by-step explanation:
Given;
Radius of the circle r = KL = 27.1 mm
Angle of unshaded region = 32°
The total angle in a circle is 360°
Angle of shaded region θ = 360° - angle of unshaded region.
θ = 360° - 32° = 328°
The Area of a circle = πr^2
Area of shaded region A = (θ/360)πr^2
Substituting the given values;
A = (328/360)×π × 27.1^2
Area of shaded region A = 2102.13 mm^2
The numbers 7, 11, 12, 13, 14, 18, 21, 23, 27, and 29 are written on separate cards, and the cards are placed on a table with th

Answer:
3/10
Step-by-step explanation:
<em>Step 1 : Write the formula of calculating probability</em>
Probability = Number of favourable outcomes/Number of total outcomes
<em>Step 2 : Identify the favourable (requires) outcomes and the total outcomes</em>
- Total outcomes are the total cards that are placed on the table = 10 cards
- The favourable outcomes are the number of cards that have an even number on them.
12, 14, 18 = 3 cards
<em>Step 3 : Substitute the values in the formula</em>
Probability = Number of favourable outcomes/Number of total outcomes
Probability = 3/10
Therefore, the probability of picking a card with and even number is 3/10.

We are given with
random samples = 300 batteries
defective samples = 9 batteries
level of significance = 0.1
Using the P-table values and using the given values, we see that the number of defective batteries are really less than 5%
Answer:
least = 315 grams
great = 324 grams
Step-by-step explanation:
31.5 grams nearest gram is 32 grams
so 31.5 x 10 packets is 315 grams
also, 32.4 grams nearest gram is 32 grams
so 32.4 x 10 packets is 324 grams
hope it helps :D
