Reptile [31]

Answer:

The probability is $P(|p-\^{p}| > 0.03) = 0.0040$

Step-by-step explanation:

From the question we are told that

The population proportion is $p = 0.07$

The mean of the sampling distribution is $\mu_p = 0.07$

The sample size is n = 600

Generally the standard deviation is mathematically represented as

$\sigma_p = \sqrt{\frac{p (1 -p)}{n} }$

=> $\sigma_p = \sqrt{\frac{0.07(1 -0.07)}{600} }$

=> $\sigma_p = 0.010416$

Generally the probability that the proportion of airborne viruses in a sample of 600 viruses would differ from the population proportion by greater than 3% is mathematically represented as

$P(|p-\^{p}| > 0.03) = 1 - P(|p -\^{p}| \le 0.03)$

=> $P(|p-\^{p}| > 0.03) = 1 - P(-0.03 \le p -\^{p} \le 0.03 )$

Now add p to both side of the inequality

=> $P(|p-\^{p}| > 0.03) = 1 - P( 0.07-0.03 \le \^{p} \le 0.03+ 0.07 )$

=> $P(|p-\^{p}| > 0.03) = 1 - P(0.04 \le \^{p} \le 0.10 )$

Now converting the probabilities to their respective standardized score

=> $P(|p-\^{p}| > 0.03) = 1 - P(\frac{0.04 - 0.07}{0.010416} \le Z \le \frac{0.10 -0.07}{0.010416} )$

=> $P(|p-\^{p}| > 0.03) = 1 - P(-2.88 \le Z \le 2.88 )$

=> $P(|p-\^{p}| > 0.03) = 1 - [P(Z \le 2.88) - P(Z \le -2.88)]$

From the z-table

$P(Z \le 2.88) = 0.9980$

and

$P(Z \le -2.88) = 0.0020$

So

$P(|p-\^{p}| > 0.03) = 1 - [0.9980 - 0.0020]$

=> $P(|p-\^{p}| > 0.03) = 0.0040$

Expand and simplify 2(5x+4)+3(2x-1)

stepladder [879]

2(5x+4)+3(2x-1)

Use the distributive property for both sets of parenthesis:

2(5x+4) = 2*5x + 2*4 = 10x+8

3(2x-1) = 3*2x - 3*1 = 6x-3

Now you have:

10x+8 + 6x-3

Now combine like terms:

10x + 6x = 16x

8-3 = 5

The final answer is 16x+5

Which relation is a function? {(–4, –6), (–3, –2), (1, –2), (1, 0)} {(–2, –12), (–2, 0), (–2, 4), (–2, 11)} {(0,1), (0, 2), (1,

Blababa [14]

Answer:

$\{(8, 1), (4, 1), (0,1), (-15, 1)\}$

Step-by-step explanation:

Given

$\{(-4, -6), (-3, -2), (1, -2), (1, 0)\}$

$\{(-2, -12), (-2, 0), (-2, 4), (-2, 11)\}$

$\{(0,1), (0, 2), (1, 2), (1, 3)\}$

$\{(8, 1), (4, 1), (0,1), (-15, 1)\}$

Required

Determine which is a function

A relation is divided into 2; (x,y)

Where x represents the range and y stands for the domain

For a relation to be a function, the x column must be unique; in other words, there must be only one occurrence of x

Testing each of the given options

A. $\{(-4, -6), (-3, -2), (1, -2), (1, 0)\}$

Start by splitting the relation into x and y columns

$(x,y)$

$(-4, -6)$

$(-3, -2)$

$(1, -2)$

$(1, 0)$

Notice that the third and fourth relation has the same x value of 1;

<em>Hence, this is not a function</em>

B. $\{(-2, -12), (-2, 0), (-2, 4), (-2, 11)\}$

Start by splitting the relation into x and y columns

$(x,y)$

$(-2, -12)$

$(-2, 0)$

$(-2, 4)$

$(-2, 11)$

Notice that all relations has the same x value of -2;

<em>Hence, this is also not a function</em>

C. $\{(0,1), (0, 2), (1, 2), (1, 3)\}$

Start by splitting the relation into x and y columns

$(x,y)$

$(0, 1)$

$(0, 2)$

$(1, 2)$

$(1, 3)$

Notice that the first and second relation has the same x value of 0 and the third and fourth relation has the same x value of 1;

<em>Hence, this is also not a function</em>

D. $\{(8, 1), (4, 1), (0,1), (-15, 1)\}$

Start by splitting the relation into x and y columns

$(x,y)$

$(8, 1)$

$(4, 1)$

$(0, 1)$

$(-15, 1)$

Notice that relation has the unique x values of 8, 4, 0 and -15

<em>Hence, this relation is a function</em>
