This question is incomplete, the complete question is;

Radio frequency identification (RFID) is an electronic scanning technology that can be used to identify items in a number of ways. One advantage of RFID is that it can eliminate the need to manually count inventory, which can help improve inventory management. The technology is not infallible, however, and sometimes errors occur when items are scanned. The probability that a scanning error occurs is 0.0062.

- find the probability that the number of items scanned incorrectly is between 14 and 25​, ​inclusive, from the next 4600 items scanned.

Answer:

the probability that the number of items scanned incorrectly is between 14 and 25​, ​inclusive, from the next 4600 items scanned is 0.2819

Step-by-step explanation:

Given that;

n = 4600

p = 0.0062

now mean of distribution μ  = n × p = (4600 × 0.0062) = 28.52

standard deviation σ = √(np(1-p)) =  √(4600 × 0.0062(1 - 0.0062 ))  = 5.3238

for normal distribution z-score = (X-μ) / σx    

therefore from the normal approximation of continuity correction and binomial distribution;

probability = P(13.5 < X < 25.5)

= P( -2.82 < Z < -0.57 )

= 0.2853 - 0.0024

= 0.2819

therefore the probability that the number of items scanned incorrectly is between 14 and 25​, ​inclusive, from the next 4600 items scanned is 0.2819

The p-value for the test statistic: [tex]Z_o=-1.96[/tex] is 0.025.

In statistics, the p-value is a measure that quantifies the strength of evidence against a null hypothesis. It represents the probability of observing a result as extreme as, or more extreme than, the one obtained in a statistical test, assuming that the null hypothesis is true.

The null hypothesis, denoted as H₀, represents the default or initial assumption that there is no significant difference or relationship between variables or no effect of a treatment. The alternative hypothesis, denoted as H₁, suggests the existence of a significant difference or relationship.

The p-value for the test statistic: [tex]Z_o=-1.96[/tex]:

p-value = P{[tex]Z_o < -1.96[/tex]}

             = 0.025.

So, the required p-value is 0.025.

Answer:

$29.01

Step-by-step explanation:

According to my calculations, an item with an original price tag of $82.88 that is marked down by 35% will have a sales price of $53.87 -- a savings of $29.01.

(1 - (30 / 100)) * $30.00

Sale Price = (1 - 0.30) * $30.00

Sale Price = 0.70 * $30.00

Sale Price = $21.00

Answer:

12000

Step-by-step explanation:

If you mean one side of the stepping stone is 20 inches then you would multiply 20 by 20 to get the area of one, since that would be multiplying length times width (the area formula). The area of one would result in 400 and you would then multiply this by the thirty tiles (400 times 30) to get 12000.

Answer:

Step-by-step explanation:

The answer would be 80 because 252+x/4 =83 x=80

The lowest score that Gil can earn on the fourth and final test of the term if he wants to have an average of at least 80.

What is average?
The ratio of total sum in a given set to all the values in the data set is the mean value, which is the definition of the average. In mathematics, the central value of the a set of data is expressed as the average of a list of data. It is defined mathematically as the ratio of the total number of data points to a number of units in the list. In terms of statistics, the term "mean" also refers to the average of a particular set of numerical data. The average of 2, 3, and 4 is, for instance, (2+3+4)/3 = 9/3 = 3. The central value of 2, 3, and 4 in this instance is 3, so. Finding the mean value of the a group of numbers is the definition of average.

According to question,
[tex]\frac{86+88+78+x}{4} = 83[/tex]⇒ [tex]x = 80[/tex]
Hence, Gill can score 80.

Step-by-step explanation:

Answer: y=-5x+2

Step-by-step explanation: Luckily for you, they already pretty much gave you all the information you need for this problem. Keep in mind that the standard form for linear equations is y=mx+b, where m is slope and b is figure 0, or the y-intercept. So, all you have to do is substitute the values for the given information. You know that -5 is the slope, m, and (0,2) is the y-intercept, or b (you know that this is the y-intercept because x is at zero). So, you'd be left with y=-5x+2.

Answer:

  40 units²

Step-by-step explanation:

You can figure the side lengths using the distance formula, or you can use a formula for finding area from coordinates. The latter looks like ...

  [tex]\displaystyle A=\dfrac{1}{2}\left|\sum\limits_{k=1}^n{x_k(y_{k-1}-y_{k+1})}\right|\qquad\text{where $y_0=y_n$ and $y_{n+1}=y_1$}[/tex]

So, the area is ...

  A = (1/2)|(-6(-5-1) +2(-1-7) +2(1-3) +3(7+3) +3(3+5) -5(-3+1)|

  = (1/2)|36 -16 -4 +30 +24 +10| = (1/2)(80)

 A = 40

The area of the figure is 40 units².

Rate of change = [tex] \frac{9}{2} = 4.5 [/tex].

Step-by-step explanation:

Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex].

Use the coordinates of two points on the graph. (Any point can be chosen. We will still arrive at the same rate of change).

Using (2, 9) and (4, 18),

Let,

[tex] (2, 9) = (x_1, y_1) [/tex]

[tex] (4, 18) = (x_2, y_2) [/tex]

Complete Question

Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal places

           x        1        2         3           4          5

         P(x)      0     0.31     0.12     0.23       0.4

Answer:

The value is  [tex]\sigma = 0.89[/tex]

Step-by-step explanation:

From the question we are told that

  The probability distribution is  

           x        1        2         3           4          5

         P(x)      0     0.31     0.12     0.23       0.4

So

           [tex]x^2[/tex]     1           4         9          16           25  

Generally the mean is mathematically represented as

            [tex]E(X) = \sum [x * P(x)][/tex]

=>         [tex]E(X) = (1 * 0) + (2 * 0.31 ) + (3 * 0.12 ) + (4 * 0.23) + (5 * 0.4 )[/tex]

=>         [tex]E(X) = 3.9[/tex]

Generally  

      [tex]E(X^2) = \sum [X^2 * P(x)][/tex]

=>   [tex]E(X^2) = (1 * 0) + (4 * 0.31 ) + (9 * 0.12) + (16 * 0.23) + (25 * 0.4)[/tex]

=>   [tex]E(X^2) =16[/tex]

Generally the variance of this probability distribution is

      [tex]V(X) = E(X^2) - [E(X)]^2[/tex]

     [tex]V(X) = 16 - 3.9^2[/tex]

    [tex]V(X) = 0.79[/tex]

Generally the standard deviation of this probability distribution is  

       [tex]\sigma = \sqrt{V(x)}[/tex]

=>    [tex]\sigma = \sqrt{0.79}[/tex]

=>    [tex]\sigma = 0.889[/tex]

Answer:

2. m∠1 = 129°

3. m∠1 = 37°

Step-by-step explanation:

We know that the sum of all interior angles in a triangle adds up to 180°.

2. To find measure 1 for problem 2, we can see that ∠1 is a supplementary angle with the interior angle in side

180°-(67°+62°)

180°-129°

51°

Now that we found the missing interior angle, we can find ∠1

180°-51° = 129°

m∠1 = 129°

3. Same thing as well for this problem except we're going to be going reverse we need to find the supplementary angle first, then we can find m∠1.

180°-152° = 28°

Now that we found the interior angle, we can find m∠1

180° - (115°+28°)

180°-(143°)

37°

m∠1 = 37°

Answer:

7 large boxes and 2 small boxes

Step-by-step explanation:

if you take 350 and times it by 7 you get 2450 then add 2 small boxes which are 50 each and you have 2550 and 5 more large boxes then small

The contractor purchased 2 no. of small boxes and 7 large boxes.

A linear equation is an algebraic equation of highest degree 1.

According to the given question A contractor needs to buy nails to build a house.

The nails come in small boxes and large boxes. Each small box has 50 nails and each large box has 350 nails.

The contractor bought 5 more large boxes than small boxes,So assuming he bought x no. of small boxes.

∴ He bought (x+5) nos. of large boxes.

So, 50(x) + 350(x+5) = 2550.

50x + 350x + 1750 = 2550.

400x = 2550 - 1750.

400x = 800.

x = 2.

∴ Large no. of boxes he purchased is 7.

Step-by-step explanation:

The speed on the zip line is 22 feet per second.

let's use the conversion rate below

1 miles  = 5280 foot

1 hour = 3600 seconds

The  rate is measured in miles per hour. Let's convert it to feet per seconds. Therefore,

Let convert the distance first

1 miles  = 5280 foot

15 miles = ?

cross multiply

distance in miles = 5280 × 15 = 79200 foots

let convert the hours to seconds

3600 seconds = 1 hour

Therefore,

speed in foot per seconds = 79200 / 3600 = 22 ft/secs
