Given:
Number of sides = 7
Apothem = 8 meters
Side length = 7.7 meters
To find:
The area of the regular polygon.
Solution:
We know that,
Area of a regular polygon is
[tex]A=\dfrac{1}{2}pa[/tex] ...(i)
where, p is perimeter and a is apothem.
Perimeter of a regular polygon is the product of number of sides and side length.
[tex]p=7\times 7.7[/tex]
[tex]p=53.9[/tex]
Substituting p=53.9 and a=8 in (i), we get
[tex]A=\dfrac{1}{2}(53.9)(8)[/tex]
[tex]A=(53.9)(4)[/tex]
[tex]A=215.6[/tex]
Therefore, the area of the regular polygon is 215.6 m².
A certain manufacturing plant produces electric fuses of which 20% are defective. Find the probability that in a sample of 8 fuses selected at random there will be atleast one defective and not more than one defective.
Answers
Answer:
0.419
Step-by-step explanation:
To calculate this, we shall make use of Bernoulli approximation of Binomial distribution
if 20% are defective, then 80% are not defective
Probability of selecting a defective fuse is 20/100 = 0.2
Probability of selecting a non defective one is 0.8
Probability of at least 1 being defective is = 1 - Probability of none being defective
Mathematically that will be;
0.8^8 = 0.168
The above is probability of none defective
So the probability of at least one will be
1 - 0.168 = 0.832
Probability of not more than 1 means;
Probability of none + probability of 1 being defective
We already have probability of none above
Probability of 1 being defective means 8 will be non defective
The probability in this case is;
8 C 1 0.2^1 0.8^7
= 8 * 0.2 * 0.8^7 = 0.336
Add this to the probability of none = 0.336 + 0.168 = 0.504
So the probability that we want to calculate from the question will be;
Probability of at least one defective * probability of not more than one defective
= 0.832 * 0.504 = 0.419

Answer:
Step-by-step explanation:
those are 2 lines, and to graph them find 2 points for each to draw a line trough them
line 1
y-2x=0 so y=2x
pick any value for x

Draw a line trough points (1,2) and (3,6)
line 2
y=4x+3
(x=1, y=4*1+3=7), (x= -1, y= 4(-1)+3= -1)

Given : last 10 run scores Colin got in cricket: 1, 16, 5, 25, 26, 32, 5, 7, 1, 7
Colin plays cricket again on Sunday. He gets 29 runs.
To find : a) Work out Colin's mean score.
b) What is his new mean score
Solution:
last 10 run scores Colin got in cricket
1, 16, 5, 25, 26, 32, 5, 7, 1, 7
Total Score = 1 + 16 + 5 + 25 + 26 + 32 + 5 + 7 + 1 + 7 = 125
Total Innings = 10
Mean Score = 125/10 = 12.5
Colin plays cricket again on Sunday. He gets 29 runs.
=> New Total Score = 125 + 29 = 154
New Total Innings = 10 + 1 = 11
New Mean Score = 154/11 = 14
Mean Score = 12.5
New Mean Score = 14
Hope this helps! ;)

A. 20 miles
B. 15 miles
C. 12 miles
D. 25 miles
Answers
Step-by-step explanation:
2/3 of diatance = 10 miles
3/3 of distance = 10 * (3/2) = 15 miles.
The distance between the houses is 15 miles. (B)
Let the total distance covered= x
Distance covered= 10 miles
According to the question,
2/3 of x= 10
=> 2/3 × x= 10
=> 2x/3= 10
=> 2x= 10× 3
=> 2x= 30
=> x= 30/2
=> x= 15
Bob's house is 15 miles away from Henry's house.

Sapphire and Abe are shelving books at a public library. Sapphire shelves 12 books at a time, whereas Abe shelves 18 at a time. If they end up shelving the same number of books, what is the smallest number of books each could have shelved.
Answers
Answer: 36
Step-by-step explanation:
Given: Sapphire shelves 12 books at a time, whereas Abe shelves 18 at a time.
If they end up shelving the same number of books, what is the smallest number of books each could have shelved = LCM (12,18)
12 = 2 x 2 x 3
18 = 2 x 3 x 3
LCM (12, 18) = 2 x 2 x 3 x 3 = 36
Hence, the smallest number of books each could have shelved = 36

36
