Solve for x<br> X/8 - 3/4 = 5/8

igomit [66]

X= 11
When you add 3/4 to 5/8, you get 11/8. Then you have to multiply each side with (8/1). You get (88/8). That equals 11.

Answer:

e. m = 16.2; s = 1.27

Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Let X the random variable of interest, on this case we can assume that the distribution for X is given by:

$X \sim Binom(n=18, p=0.9)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

Normal approximation

We need to check the condition in order to use the normal approximation.

$np=18*0.9=16.2 \geq 10$

So we see that we satisfy the condition and then we can apply the approximation.

If we appply the approximation the new mean and standard deviation are:

$E(X)=np=18*0.9=16.2$

$\sigma=\sqrt{np(1-p)}=\sqrt{18*0.9(1-0.9)}=1.273$

The best answer would be:

e. m = 16.2; s = 1.27

Step-by-step explanation:

5)2

6) -5

7) -4/3

If it asks x intercept, then y will be 0.

If it asks y intercept, then x will be 0.

Slope is attained by forming an equation like this:

y=mx+c, where m is the slope, and c is the y intercept.

A recent survey found that 80.5% of households has Internet access and 82% of households had cable television. Also, it was repo

kirill115 [55]

Answer: 0.878

Step-by-step explanation:

Given : P( Internet access) = 80.5%= 0.805

P(cable television) = 82% = 0.82

P( Internet access and cable television) = 74.7% =0.747

Formula: P(A or B)= P(A ) + P(B) - P(A and B)

So, P( Internet access or cable television) = P( Internet access) + P(cable television) -P( Internet access and cable television)

= 0.805+0.82-0.747

= 0.878

The probability that a randomly selected household in the survey had either Internet access or cable = 0.878
