Answer:
0.2657
Step-by-step explanation:
Given that:
Probability of Error (p) = 1/ 1000 = 0.001
Number of trials (n) = 10000
μ = (n * p) = 10000 * 0.001 = 10
Using the binomial distribution :
P(x, μ) = e^-μ (μ^x) / x!
for x = 6
P(6, 10) = e^-10 (10^6) / 6!
P(6, 10) = 0.0000453999 (1388.8888) = 0.06305541263112
for x = 7
P(7, 10) = e^-10 (10^7) / 7!
P(7, 10) = 0.0000453999 (1984.1269) = 0.09007916284731
for x = 8
P(8, 10) = e^-10 (10^8) / 8!
P(8, 10) = 0.0000453999 (2480.1587) = 0.11259895696413
P(6) + P(7) + P(8)
0.06305541263112 + 0.09007916284731+ 0.11259895696413
= 0.26573353244256
= 0.2657
The town of Springville is mapped on a coordinate grid with
the origin being at City Hall. John's house is located at the
point (-5, 7) and Bill's house is located at (-2,3). How far is it
from John's house to Billy's house?
Answer:
The distance from John's house to Bill's house is 5 units
Step-by-step explanation:
John's house is located at the point (-5,7) and Bill's house is located at (-2,3) in a map of the town of Springville.
We need to find the distance from John's house to Bill's house. We use the formula of the distance between two points:
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(w-x)^2+(z-y)^2}[/tex]
Applying the formula:
[tex]d=\sqrt{(-2+5)^2+(3-7)^2}[/tex]
[tex]d=\sqrt{3^2+4^2}[/tex]
[tex]d=\sqrt{9+16}=\sqrt{25}[/tex]
d=5
The distance from John's house to Bill's house is 5 units

62 is half of one lesss than the cube of a whole number. What is the number
Answer:
The answer is 5.
62 is half of 124
124 is one less than 125
The cube root of 125 is 5.
That is... 5 times 5 times 5 equals 125, since, 5 times 5 equals 25; and, 25 times 5 equals 125.

Convert 26.7% to an
equivalent decimal.
Answer: 26.7
First, you must remove the percentage sign, then you will get a equivalent decimal.
When we remove the % sign, we get 26.7.
The answer is 26.7. Hope this helps!
It is found that 26.7% as an equivalent decimal is 0.267.
LEt the value of which a thing is expressed in percentage is "a' so the percent that considered thing is of "a" is b%
However percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
To convert 26.7% to an equivalent decimal, we simply divide it by 100:
26.7% ÷ 100
26.7/ 100 x 100 = 0.267
Therefore, WE can conclude that 26.7% as an equivalent decimal is 0.267.

solve the following problem.
1. A leaking faucet waste about 3 liters of water a day. How many liters of water can be saved daily if 500 leaking faucets are repaired?
2. The quotient is 25 and the divisor is 14. the dividend is 353. I am the remainder what number am I?
3. Isaiah had 63 apples. He divided all apples evenly among his 9 friends. How many apples did Isaiah give to each of his friends?
4. Nancy needs 5 oranges to make a glass of orange juice. If Nancy 250 oranges, how many glasses of orange juice can she make?
Answer:
1) 1500 litres
2)Remainder = 3
3)7 apples
4)50 glasses
Step-by-step explanation:
1) We are told that a leaking faucet wastes about 3 liters of water per day.
Now, if 500 faucets are repaired, it means total number of litres saved per day = 500 × 3 = 1500 litres
2) We are told that the quotient is 25 and the divisor is 14. the dividend is 353.
Now, the quotient multiplied by the divisor should give us the dividend. Otherwise, we subtract the value we get from the dividend to get the remainder.
Thus:
Quotient × divisor = 25 × 14 = 350
This is not equal to the dividend.
Thus the remainder is;
353 - 350 = 3
Remainder = 3
3) We are told Isaiah had 63 apples.
If he divided the 63 apples among his 9 friends evenly, it means the number of apples received by each of his friends is gotten by Dividing the total number of apples by the number of friends. This gives; 63/9 = 7 apples
4) We are told Nancy needs 5 oranges to make a glass of orange juice.
Now, Nancy has 250 oranges. This means that the number of glasses of orange juice she can make is; 250/5 = 50 glasses

parallelogram ABCD has the following vertices A(0,8) B(8,4) C(2,-8) D(-6,-4) is parallelogram ABCD a rectangle, and why
Answer:
Yes, because BC is perpendicular to AB, and ABCD is a parallelgram.
Yes the parallelogram is a rectangle.
What is distance formula?The distance between coordinate P(x1 , y1) and coordinate Q(x2 , y2) is calculated using the distance formula: d = √[(x2 - x1)² + (y2 - y1)²]
Given:
ABCD is parallelogram, so its opposite sides are equal in length.
i.e., AB= CD and AD= BC
Now,
d=√(8−0)²+(4−8)
d=√(8)²+(−4)²
d=√64+16
d=√80
d=√(−6−2)²+(−4−(−8))²
d=√(−8)²+(4)²
d=√64+16
d=√80
so, AB = CD
Similarly, AD= BC = √180
Hence, a quadrilateral whose opposite side are equal called as rectangle.

The Australian sheep dog is a breed renowned for its intelligence and work ethic. It is estimated that 4 0% of adult Australian sheep dogs weigh 65 pounds or more. A sample of 1 4 adult dogs is studied. What is the standard deviation of the number of dogs who weigh 65 lb or more?
Answer:
The standard deviation of the number of dogs who weigh 65 lbs or more is 1.83.
Step-by-step explanation:
Let X represent the number of adult Australian sheep dogs weighing 65 pounds or more.
It is provided that the probability of occurrence of X is, p = 0.40.
A sample of n = 14 adult dogs is studied.
Each dog's weight is independent of the others.
The random variable X follows a Binomial distribution.
The standard deviation of a Binomial distribution is:
[tex]\sigma=\sqrt{np(1-p)}[/tex]
Compute the standard deviation of the number of dogs who weigh 65 lbs or more as follows:
[tex]\sigma=\sqrt{np(1-p)}[/tex]
[tex]=\sqrt{14\times 0.40(1-0.40)}\\\\=\sqrt{3.36}\\\\=1.83303\\\\\approx 1.83[/tex]
Thus, the standard deviation of the number of dogs who weigh 65 lbs or more is 1.83.
