The function g(n) = n2 − 16n + 69 represents a parabola.

miss Akunina [59]

Hello :
g(n) = n2 − 16n + 69
=( n²-16n+64)-64 +69.....( completing the square)
g(n) = (n-8)² +5...... (the vertex form)
the vertex is : (8,5)
the axis of symmetry is the line : n = 1

Over [174]

Answer:

The price of pretzels in 1975 = $1.80

Step-by-step explanation:

To answer this question we are assuming the steady rate means linear.Let x be the year and y be the price.

We need to find the slope

m = (y2-y1)/(x2-x1)

= (4.80-4.05)/(2015-2005)

=.75/10

= .075

The slope is .075

We can use the point slope form of the equation

y-y1 = m(x-x1)

y-4.80 = .075(x-2015)

Distribute

y - 4.80 = .075x -151.125

Add 4.80 to each side

y - 4.80+4.80 = .075x -151.125+4.80

y = .075 x - 146.325

We want to find out how much pretzels were in 1975. Put in x=1975

y = .075(1975) -146.325

y = 148.125-146.325

y=1.80

Goryan [66]

Answer: (a) P(no A) = 0.935

(b) P(A and B and C) = 0.0005

(d) P(A or B) = 0.31

Step-by-step explanation: Pareto Chart demonstrates a relationship between two quantities, in a way that a relative change in one results in a change in the other.

The Pareto chart below shows the number of people and which category they qualified each public school.

(a) The probability of a person not giving an A is the difference between total probability (1) and probability of giving an A:

P(no A) = $1-\frac{68}{1052}$
