The answer is: [C]: standard deviation ..
___________________________________
Explanation:
___________________________________
However, note that the mean of a sample from a normal population (that is, a type of "standard deviation" known as "standard deviation from a sample mean", is an "unbiased estimator" of the "population mean".

We shall represent the "sample mean" as:  x̅<span>  ; 
               (pronounced: "x-bar"; that is; "ex-bar"); this is the usual symbol                                                                                                              used; 
</span>
We shall represent the sample size as "n" ;
                                                 (This is the usual variable used; note that
                                                                                "n" is a numeric value).
__________________________________________________________
The standard deviant from the sample mean:

(n *  x̅)  / (n + 1) is a "biased estimator of the mean" that becomes "unbiased" as the sample size increases; since as "n" increases in values; the value of the entire entire expression becomes smaller (i.e the standard deviation becomes smaller.

The cost for an order of 100 kilograms of steel bars is $230. The cost for an order of 150 kilograms of steel bars is $320. Writ
luda_lava [24]

Answer:

y = 9x/5 + 50

Step-by-step explanation:

We are represent the information as coordinate (x,y)

If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)

Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;

(150, 320)

Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c

m is the slope

c is the intercept

Get the slope;

m = y2-y1/x2-x1

m = 320-230/150-100

m = 90/50

m = 9/5

Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c

230 = 9/5(100)+c

230 = 9(20)+c

230 = 180 + c

c = 230-180

c = 50

Get the required equation

y = mx+c

y = 9/5 x + 50

Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50

Suppose you have the following information. 12% of all drivers do not have a valid driver’s license, 6% of all drivers have no i
lubasha [3.4K]

Answer:

e) 0.14

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a driver does not have a valid driver's license.

B is the probability that a driver does not have insurance.

We have that:

A = a + (A \cap B)

In which a is the probability that a driver does not have a valid driver's license but has insurance and A \cap B is the probability that a driver does not have any of these things.

By the same logic, we have that:

B = b + (A \cap B)

We start finding these values from the intersection.

4% have neither

This means that (A \cap B) = 0.04

6% of all drivers have no insurance

This means that B = 0.06. So

B = b + (A \cap B)

0.06 = b + 0.04

b = 0.02

12% of all drivers do not have a valid driver’s license

This means that A = 0.12

So

A = a + (A \cap B)

0.12 = a + 0.04

a = 0.08

The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about

P = a + b + (A \cap B) = 0.08 + 0.02 + 0.04 = 0.14

So the correct answer is:

e) 0.14
