How much egg she has

Mathematics
1 answer:
Nataly [62]3 years ago
3 0

We know no eggs were left over in the groups of 7, so the total x is a multiple of 7.   We know it's an odd multiple because it's not even.  We know it ends in 1 or 6 because of the remainder of 1 with 5 but it can't end in the even 6.

So we make a list of odd multiples of 7 that end in 1.

21, 91, 161, 231, 301, ...

21 is a multiple of 3, nope

91 has a remainder of 3 when divided by 4

161 has a remainder of 2 when divided by 3

231 is a multiple of 3

301 has remainder 1 mod 2, 1 mod 3, 1 mod 4, 1 mod 5, 1 mod 6 and 0 mod 7.  It's our answer; there are bigger answers as well.

Answer: 301

Multiple simultaneous congruences may be solved by the Chinese Remainder Theorem.

Scott is on his school's academic team. On average, it takes Scott 4 minutes, with a standard deviation of 0.25 minutes, to solv
uysha [10]

Answer:

15.87% is the chance that Scott takes more than 4.25 minutes to solve a problem at an academic bowl.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 4 minutes

Standard Deviation, σ = 0.25 minutes

We standardize the given data.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(more than 4.25 minutes to solve a problem)

P( x > 4.25) = P( z > \displaystyle\frac{4.25 - 4}{0.25}) = P(z > 1)

= 1 - P(z \leq 1)

Calculation the value from standard normal z table, we have,  

P(x > 4.25) = 1 - 0.8413 = 0.1587 = 15.87\%

Thus,15.87% is the chance that Scott takes more than 4.25 minutes to solve a problem at an academic bowl.

My math teacher told me that circumstance was pie I dont know what pie is ;(
agasfer [191]

Answer:

Pie= 3.14

Step-by-step explanation:

The enclosing boundary of a curved geometric figure, especially a circle.The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!
