Answer:
And the z score for 0.4 is
And then the probability desired would be:
Step-by-step explanation:
The normal approximation for this case is satisfied since the value for p is near to 0.5 and the sample size is large enough, and we have:
For this case we can assume that the population proportion have the following distribution
Where:
And we want to find this probability:
And we can use the z score formula given by:
And the z score for 0.4 is
And then the probability desired would be:
The answer to this is 4/3
Answer:
The width w of the rectangular park = 1/2
Step-by-step explanation:
Given
The length of the rectangular park l = 2/3 miles
The area of the park A = 3/9 square miles
To determine
The width of the rectangular park w = ?
Using the formula of the Area of the rectangle
∵ Fraction rule: 
Therefore, the width w of the rectangular park = 1/2
As to what I know you can’t use the same measurements if you want to do an isosceles triangle and a equilateral one too. Isn’t there another option? Sry Imao

Demonstration, with Cuisenaire rods, that the number 7 is prime, being divisible only by 1 and 7
A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 5 is prime because 1 and 5 are its only positive integer factors, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6. The fundamental theorem of arithmetic establishes the central role of primes in number theory: any integer greater than 1 is either a prime itself or can be expressed as a product of primes that is unique up to ordering. The uniqueness in this theorem requires excluding 1 as a prime because one can include arbitrarily many instances of 1 in any factorization, e.g., 3, 1 · 3, 1 · 1 · 3, etc. are all valid factorizations of 3.</span>
