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

Find the angle 1 in this photos
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°

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, which altogether had 2550 nails. Determine the number of small boxes purchased and the number of large boxes purchased.
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.
What is a linear equation ?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.

Find the rate of change demonstrated in the graph below.
Answer:
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]
What is the equation of a line that has a slope of -5 and passes through the point (0, 2)?
A.y = -5x
B.y = 2x - 5
C.y = -5x + 2
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.

a concrete stepping stone measures 20 square inches. what is the area of 30 such stones?
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.

units²
Coordinate plane with axes labeled x and y. A closed figure is formed by a parallelogram and rectangle. The vertices are negative 6 comma negative 1, 2 comma 1, 2 comma 7, 3 comma 3, 3 comma negative 3, and negative 5 comma negative 5.
9514 1404 393
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

You are riding on a zip line. Your speed is 15 miles per hour. What is your speed in feet per second?
Answer:
22 feet per second
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

For the hypothesis test against and variance known, calculate the P-value for the following test statistic: . Round your answer to three decimal places (e.g. 98.765). P-value
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.

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]
