Answer:

Table 3 and 4

Step-by-step explanation:

Let us understand the coordinates symmetry of the graphs of quadratic equations.

In a quadratic equation, we have a polynomial in x with degree 2. Hence the result in y or P(x) do get repeated as polynomial contains $x^2$ in it.

Thus by analysing the tables we see that in table 3 , y= -10 gets repeated and in table 4 , y =4 and y=-4 repeated. Hence they are the graph of a quadratic polynomial

Super Bowl XLVI was played between the New York Giants and the New England Patriots in Indianapolis. Due to a decade-long rivalr

Diano4ka-milaya [45]

Answer:

Probability that from a sample of 200 Indianapolis residents, fewer than 170 were rooting for the Giants in Super Bowl XLVI is 0.02385.

Step-by-step explanation:

We are given that Due to a decade-long rivalry between the Patriots and the city's own team, the Colts, most Indianapolis residents were rooting heartily for the Giants. Suppose that 90% of Indianapolis residents wanted the Giants to beat the Patriots.

Let p = % of Indianapolis residents wanted the Giants to beat the Patriots = 90%

The z-score probability distribution for proportion is given by;

Z = $\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ ~ N(0,1)

where, $\hat p$ = % of Indianapolis residents who were rooting for the Giants in Super Bowl XLVI in a sample of 200 residents = $\frac{170}{200}$ = 0.85

n = sample of residents = 200

So, probability that from a sample of 200 Indianapolis residents, fewer than 170 were rooting for the Giants in Super Bowl XLVI is given by = P( $\hat p$ < 0.85)

P( $\hat p$ < 0.85) = P( $\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ < $\frac{0.85-0.90}{\sqrt{\frac{0.85(1-0.85)}{200} } }$ ) = P(Z < -1.98) = 1 - P(Z $\leq$ 1.98)

= 1 - 0.97615 = 0.02385

The above probability is calculated using z table by looking at value of x = 01.98 in the z table which have an area of 0.97615.

Therefore, probability that fewer than 170 were rooting for the Giants in Super Bowl XLVI is 0.02385.

A central angle of a circle is 90 degrees. If the diameter of the circle is 12 cm, what is the area of the segment created by co

Yanka [14]

<h3>The area of the segment created by connecting the two points on the circle created by the angle described is 28.26 square centimeter</h3>

Solution:

Given that,

A central angle of a circle is 90 degrees

diameter of the circle is 12 cm

radius = 12/2 = 6 cm

To find: Area of segment

The area of sector when angle is in degrees is:

$Area\ of\ sector = \frac{\theta}{360} \times \pi r^2$

Where,

r is radius

$\theta$ is angle in degrees

Therefore,

$Area\ of\ sector = \frac{90}{360} \times 3.14 \times 6^2\\\\Area\ of\ sector = 0.25 \times 3.14 \times 36\\\\Area\ of\ sector = 28.26$

Thus area of the segment created by connecting the two points on the circle created by the angle described is 28.26 square centimeter
