What is a quadratic function? (Brief explanation)

tino4ka555 [31]

The quadratic function has the form:

F(x) = y = a + bx + cx2

where a, b, and c are numerical constants and c is not equal to zero.

Note that if c were zero, the function would be linear.

An advantage of this notation is that it can easily be generalized by adding more terms. We could for example write equations such as

y = a + bx + cx2 + dx3

y = a + bx + cx2 + dx3 + ex4

Answer:

Equation: y = 65x

Randomly pick a x and y value and plug into above equation, if they don't equal then the x and y you've picked cannot be on this table.

Step-by-step explanation:

Pick any two points to find slope, let's got with (3, 195) and (4, 260):

slope m = (y₂- y₁) / (x₂ - x₁)

= (260 - 195) / (4 - 3)

= 65 / 1

m = 65

Find y-intercept by using m from above and another point from your table, let's go with (5, 325):

y = mx + b

325 = 65(5) + b

325 = 325 + b

b = 0

Use m and b to form equation of line:

y = mx + b

y = 65x + 0

y = 65x

Check:

point (3, 195): 195 = 65(3) ====> 195 = 195

point (4, 260): 260 = 65(4) ====> 260 = 260

point (5, 325): 325 = 65(5) ====> 325 = 325

point (6, 390): 390 = 65(6) ====> 390 = 390

Example of a point that doesn't belong on table:

point (8, 500): 500 = 65(8) ====> 500 ≠ 520

In a study of the accuracy of fast food drive-through orders, one restaurant had 40 orders that were not accurate among 307 ord

klemol [59]

Answer:

We conclude that the rate of inaccurate orders is greater than 10%.

Step-by-step explanation:

We are given that in a study of the accuracy of fast food drive-through orders, one restaurant had 40 orders that were not accurate among 307 orders observed.

Let p = population proportion rate of inaccurate orders

So, Null Hypothesis, $H_0$ : p $\leq$ 10% {means that the rate of inaccurate orders is less than or equal to 10%}

Alternate Hypothesis, $H_A$ : p > 10% {means that the rate of inaccurate orders is greater than 10%}

The test statistics that will be used here is One-sample z-test for proportions;

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

where, $\hat p$ = sample proportion of inaccurate orders = $\frac{40}{307}$ = 0.13

n = sample of orders = 307

So, the test statistics = $\frac{0.13-0.10}{\sqrt{\frac{0.10(1-0.10)}{307} } }$

= 1.75

The value of z-test statistics is 1.75.

Also, the P-value of the test statistics is given by;

P-value = P(Z > 1.75) = 1 - P(Z $\leq$ 1.75)

= 1 - 0.95994 = 0.04006

Now, at 0.05 level of significance, the z table gives a critical value of 1.645 for the right-tailed test.

Since the value of our test statistics is more than the critical value of z as 1.75 > 1.645, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region.

Therefore, we conclude that the rate of inaccurate orders is greater than 10%.
