Which of the following best describes the relationship shown in the equation below?

viva [34]

Answer:

C. this is not a functional relationship.

Step-by-step explanation:

In other words, for each x-value, there is only one corresponding y-value.

For the equation x2 + y2 = 10, find the y-value for a given x-value.

Let x = 1.

Since (-3) · (-3) = 9 and 3 · 3 = 9, there are two y-values for x = 1.

Step-by-step explanation:

Step 1: Define

Identify.

y = x² + 8x

Step 2: Find Roots

[Quadratic] Factor: y = x(x + 8)
[Quadratic] Set up [Solve]: 0 = x(x + 8)
[Quadratic] Define: x = 0, -8

∴ the roots of the quadratic equation y = x² + 8x is equal to 0 and -8.

A spinner is divided into six equal-sized sectors labeled 1 through 6. Dwayne spins this spinner 12 times. Let X

slavikrds [6]

Answer:

b) μ = 2 and σ = 1.29

Step-by-step explanation:

Step(i):-

Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6

Given that the probability of labelled '1'

$p = \frac{1}{6}$ =0.16

q = 1-p = 1- 0.16 = 0.84

Let 'X' be a random variable in binomial distribution

The mean of the binomial distribution

μ = n p

μ = $12 (\frac{1}{6} ) = 2$

The mean of the binomial distribution = 2

Step(ii):-

The standard deviation of X

σ $= \sqrt{npq}$

σ = $\sqrt{12(0.16)(0.84}$

σ = $1.269$

The standard deviation of the binomial distribution

σ = $1.269$
