The degree of the polynomial p(y) =(y-4)^3-y^3 is<br><br>Plz urgent

Scilla [17]

Answer:

The degree of polynomial is 2

Step-by-step explanation:

Given

$p(y) = (y -4)^3 - y^3$

Required

The degree

When expanded, $p(y) = (y -4)^3 - y^3$ is:

$p(y) =y^3-12y^2+48y-64-y^3$

Collect like terms

$p(y) =-12y^2+48y-64-y^3+y^3$

$p(y) =-12y^2+48y-64$

<em>The degree of freedom is 2</em>

The gradient of A(6,2) B(3,-3)

Anestetic [448]

Answer:

$\sf gradient: \dfrac{5}{3}$

Explanation:

$\sf slope/gradient: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

Given points: A(6,2), B(3,-3)

$\rightarrow \sf slope: \dfrac{-3-2}{3-6}$

$\rightarrow \sf slope: \dfrac{-5}{-3}$

$\rightarrow \sf slope: \dfrac{5}{3}$

1. The number of pizzas consumed per month by university students is normally distributed with a mean of 12 and a standard devia

9966 [12]

Answer:

0.00621

Step-by-step explanation:

To solve for this question: we would be making use of the z score formula.

z = (x - μ)/σ

where

x is the raw score

μ is the population mean

σ is the population standard deviation

Step 1

Find the Standard Error

From the above question, we are given number of samples, hence, the standard deviation we would use for our z score is Standard error.

Standard error = Standard deviation/√n

Where n = number of samples = 25

Standard deviation = 4

Standard error = 4/√25

= 4/5

= 0.8

Step 2

Calculate the z score

Since we are given number of samples in the question,

z score = z = (x - μ)/σ

where

x is the raw score = 14

μ is the population mean = 12

σ is the standard error = 0.8

z score = 14 - 12/0.8

z score = 2.5

Step 3

We find the Probability.

The probability that a randomly selected sample of 25 students will consume on average more than 14 pizzas per month is calculated as:

We find the Probability of the Z score 2.5 using a Z table.

P(z = 2.5) = P(x ≤ 14) = 0.99379

P(x > 14) = 1 - P(x<14)

= 1 - 0.99379

= 0.0062097

Approximately ≈ 0.00621

Therefore, the probability that a randomly selected sample of 25 students will consume on average more than 14 pizzas per month is

0.00621
