Answer:
The number of words that Hugo wrote in the test of Wednesday (74) is at a distance of 1.4545 standard deviations (11) to the right of his mean (58)
Step-by-step explanation:
A normal random variable with mean Mu = 58 and standard deviation sd = 11 is standardized with the transformation (z-score):
Z = (X - Mu) / sd = (X - 58) / 11
For a value of 74 for X, Z = (74 - 58) / 11 = 1.4545 > 0.
The z-score when X = 74 is 1.4545 > 0
This means that the number of words that Hugo wrote in the test of Wednesday (74) is at a distance of 1.4545 standard deviations (11) to the right of his average (58)
Answer:
The value of c in the equation c =6.
Step-by-step explanation:
In mathematics, a perfect square or a square number is an integer that is the square of an integer. In different words, it is the product of an integer with itself. For example, 9 is a square number because it can be written in 3 × 3.
The normal notation for the square of a number n is not the product n × n, but the equivalent exponentiation n2, which is generally pronounced as "n square". The square number of the name results from the name of the form. The unit area is defined as the area of a unit square (1 × 1). Consequently, a square of lateral length n has the area n2.
Square numbers are not negative. Another way to say that an integer (not negative) is a square is to make its square root an integer again.
For example, √9 = 3, so, 9 is a quadratic number.
A positive integer that has no perfect square divisors other than one is called without a square.
24.2² = 24.2 × 24.2 =585.64=abac.
From above equation, a=5,b=8,c=6.
50+55x=y 200+45x=y
We have a system of equations.
