The graph below shows two polynomial functions, f(x) and g(x):
neonofarm [45]
The answer is '<span>f(x) is an odd degree polynomial with a positive leading coefficient'.

An odd degree polynomial with a positive leading coefficient will have the graph go towards negative infinity as x goes towards negative infinity, and go towards infinity as x goes towards infinity.

An even degree polynomial with a negative leading coefficient will have the graph go towards infinity as x goes toward negative infinity, and go towards negative infinity as x goes toward infinity.

g(x) would have a a positive leading coefficient with an even degree, as the graph goes towards infinity as x goes towards either negative or positive infinity.

Statisticians use ______ scores to divide the ______ under a curve the way people use a knife to cut pizza. Just as the pizza is
solong [7]

Answer:

Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.

Step-by-step explanation:

Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.

z-score:

  • A z-score is a numerical measurement which is measured in terms of standard deviations from the mean.
  • Formula:

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

  • If a z-score is 0, it tells that the data point is same as the mean.
  • Area under the normal curve is 1.

A major car dealership has several stores in a big city. The owner wants to determine if there is a difference in the proportion
Gemiola [76]

Answer:

confidence interval = ( -0.38 , 0.08 )

Step-by-step explanation:

Given data :

n1 = 55 , n2 = 60 ,

Let P1 ( proportion of SUV sales at store A ) = 30 / 55 = 0.55

P2 ( sample proportion of SUV sales at store B ) = 42/60 = 0.70

The Z-value at 99% confidence Interval = 2.58

<u>Determine the 99% confidence interval for difference in proportion</u>

applying the formula below

( P1 - P2 ) ± Z ( \sqrt{p1( 1-p1)/n1  +  p2(1-p2)/n2}

Input values above into equation

confidence interval = ( -0.38 , 0.08 )
