Answer:

Mean would increase

Median would stay the same

Step-by-step explanation:

The mean would increase because the lowest number would not make the mean lower

The median would stay the same because there are three numbers with the value of 48, which is the median, and if 45 is gone, it would stay the same

Answer:

Kindly check explanation

Step-by-step explanation:

A.) Rearranged data (ascending order)

174, 175, 178, 184, 185, 185, 185, 185, 188, 190, 200, 203, 205, 206, 210, 211, 211, 212, 212, 215, 215, 220, 223, 228, 230, 232, 241, 241, 242, 245, 247, 250, 250, 259, 260, 260, 265, 265, 270, 272, 273, 275, 276, 278, 280, 280, 285, 285, 286, 290, 290, 295, 302

Size of data, n = 53

B.) median :

1/2*(n+1)th term

1/2 * (53 + 1)

1/2 *54th term = 27 th term

= 241

C.) first quartile (Q1) :

1/4*(n+1)th term

1/4 * (53 + 1)

1/4 *54th term = 13.5

(13 + 14)th term / 2

(205 + 206) /2

= 205.5

D.) third quartile (Q3) :

3/4*(n+1)th term

3/4 * (53 + 1)

3/4 *54th term = 40.5

(40 + 41)th term / 2

(272 + 273) /2

= 272.5

Answer:

Subtract 4 from both sides

Step-by-step explanation:

Subtracting 4 from both sides isolates the variable and is the fastest way to solve the equation, which results in x > -12.

In a manufacturing plant that produces new computers, a 0.15 probability exists that a computer will be defective. if five compu

Sindrei [870]

The probability that all of them will be defective is 0.0000759375

Explanation

The general Binomial Probability formula is....

$P= ^nC_{r}*p^r*(1-p)^n^-^r$ , where p is the probability of success, n is the total number of trials and r is the desired numbers of trials.

Given, the probability that a computer will be defective is 0.15 , so p = 0.15

Five computers are manufactured and we need to find the probability that all of them will be defective. That means, n = 5 and r = 5

Now according to the above formula....

$P= ^5C_{5}*(0.15)^5*(1-0.15)^5^-^5 \\ \\ P= 1*(0.15)^5* (0.85)^0\\ \\ P=(0.15)^5 =0.0000759375$

So, the probability that all of them will be defective is 0.0000759375
