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
Brain weights are normally distibuted with mean 1400.48 grams and standard deviation 106.33 grams. Find the 80th percentile of this distribution.
Answer:
The 80th percentile of the distribution is 1,490.01 grams
Step-by-step explanation:
Here, we want to find the 80% of the distribution
80% means 80/100 = 0.8
We need to get the z-score equivalent to 80th percentile;
This is equal to 0.842
Mathematically;
z-score = (x - mean)/SD
we want to calculate x here;
0.842 = (x - 1400.48)/(106.33)
106.33(0.842) + 1400.48 = x
x = 1,490.00986 which is 1,490.01 grams to 2 decimal places
Find a radical expressions for the perimeter of the shaded triangle Simplify the expression.
Answer:20+4√17
Step-by-step explanation:
2 of 3 sides are 16 and 4 units . The angle between them is 90 degrees.
So we can find the length of the third side using Pitagor theorem.
c= SQRT( 16²+4²)= sqrt (256+16)= sqrt (272)
So the perimeter of the shaded triangle is equal to
P= 4+16+sqrt(272)=20+4√17
The radical expressions for the perimeter of the shaded triangle is 20 + 4√17
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a rectangle shown in the picture with dimensions.
Using Pythagoras theorem;
The inclined length = √(4²+16²) = √272 = 4√17
The perimeter of the shaded region = 16 + 4 + 4√17
Perimeter = 20 + 4√17
Thus, the radical expressions for the perimeter of the shaded triangle is 20 + 4√17

If (Triangle)ABC is similar to (Triangle)EDC, what is the value of x?
Answer:
37.5 (G)
Step-by-step explanation:
Set up a proportion:
[tex] \frac{40}{100} = \frac{15}{x} [/tex]
Next cross multiply
[tex](15)(100) = (40)(x)[/tex]
[tex]1500 = 40x[/tex]
Lastly solve for x by dividing both sides by 40
[tex]\frac{1500}{40} = \frac{40x}{40} [/tex]
[tex]x = 37.5[/tex]

Your friend has a mold that holds 3/4 of a cup of root beer if she has six cups of root beer how many popsicles can she make
Answer:
8
Step-by-step explanation:
If you turn 8 into a fraction you'll get 24 / 4
then you divide 24/4 by 3/4 you'll get 8
Answer:
Your friend can make 8 popsicles
Explanation:
Convert any mixed numbers to fractions. Then your initial equation becomes:
6/1 ÷ 3/4 = ?
Applying the fractions formula for division (flip the second fraction and multiply):
6/1 x 4/3 = 24/3
Simplify 24/3, the answer is:
8 popsicles

my recipe for apple cider punch calls for 2 quarts of apple cider, three teaspoons of cinnamon, and one pint of lemon-lime soda. This will make enough for 8 people. in my neighborhood, there are 40 people. how much do I need of each ingredient for my neighborhood to share
✨Answer:✨
10 quarts of apple cider, 15 teaspoons of cinnamon, 5 pints of lemon lime soda.
✨Step-by-step explanation:✨
40 people in your neighborhood ÷ 8 people (how much 1 recipe can feed) = 5 punches so you can feed 40 people
2 quarts of apple cider x 5 = 10 quarts of apple cider
3 teaspoons of cinnamon x 5 = 15 teaspoons of cinnamon
1 pint of lemon-lime soda x 5 = 5 pints of lemon-lime soda

g Find two positive numbers whose sum is 380 and whose product is a maximum. You MUST use optimization methods to solve this.
Answer:
The first number is 190 and the second number is also 190
Step-by-step explanation:
let the first number = x
let the second number = y
The sum of the numbers is given by;
x + y = 380
y = 380 - x
The objective function is given by;
F = xy
F = x(380 -x)
F = 380x - x²
Take the derivative of the function;
F' = 380 - 2x
Find the critical points;
380 - 2x = 0
2x = 380
x = 380 / 2
x = 190
Determine the second number, y;
y = 380 - x
y = 380 - 190
y = 190

To rent a certain meeting room, a college charges a reservation fee of $39 and an additional fee of $5.70 per hour. The film club
wants to spend less than $67.50 on renting the meeting room.
What are the possible amounts of time for which they could rent the meeting room?
Use t for the number of hours the meeting room is rented, and solve your inequality for t.
t<5
39 + 5.7t < 67.5
-39
5.7t < 28.5
divide by 5.7
t < 5

(1 1/2,1) (4,6) (18,12) (0,0) (2 1/2. 3 3/4 )
Answer:
[tex]2.\ \ (4,6)[/tex]
[tex]4.\ \ (0,0)[/tex]
[tex]5.\ \ (2\frac{1}{2},3\frac{3}{4})[/tex]
Step-by-step explanation:
Given
[tex]y = 1\frac{1}{2}x[/tex]
Required
Determine if the given points is on the graph
First,, we rewrite [tex]y = 1\frac{1}{2}x[/tex] as
[tex]y = \frac{3}{2}x[/tex]
[tex]1.\ \ (1\frac{1}{2},1)[/tex]
This can be interpreted as:
[tex]x = 1\frac{1}{2}[/tex]
[tex]y = 1[/tex]
Substitute [tex]x = 1\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * 1\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * \frac{3}{2}[/tex]
[tex]y = \frac{9}{4}[/tex]
This isn't equal to the given value of y.
Hence: [tex](1\frac{1}{2},1)[/tex] is not a point on the graph
[tex]2.\ \ (4,6)[/tex]
Here,
[tex]x = 4[/tex]
[tex]y = 6[/tex]
Substitute [tex]x = 4[/tex]
[tex]y = \frac{3}{2} * 4[/tex]
[tex]y = \frac{3 * 4}{2}[/tex]
[tex]y = \frac{12}{2}[/tex]
[tex]y = 6[/tex]
This point is on the graph
[tex]3.\ \ (18,12)[/tex]
Here,
[tex]x = 18[/tex]
[tex]y = 12[/tex]
Substitute [tex]x = 18[/tex]
[tex]y = \frac{3}{2} * 18[/tex]
[tex]y = \frac{3 * 18}{2}[/tex]
[tex]y = \frac{54}{2}[/tex]
[tex]y = 27[/tex]
This isn't equal to the given value of y.
Hence: [tex](18,12)[/tex] is not a point on the graph
[tex]4.\ \ (0,0)[/tex]
Here, we have
[tex]x = 0[/tex]
[tex]y = 0[/tex]
Substitute [tex]x = 0[/tex]
[tex]y = \frac{3}{2} * 0[/tex]
[tex]y = 0[/tex]
Hence:
This point is on the graph
[tex]5.\ \ (2\frac{1}{2},3\frac{3}{4})[/tex]
Here
[tex]x =2\frac{1}{2}[/tex]
[tex]y = 3\frac{3}{4}[/tex]
Substitute [tex]x =2\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * 2\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * \frac{5}{2}[/tex]
[tex]y = \frac{15}{4}[/tex]
[tex]y = 3\frac{3}{4}[/tex]
Hence:
This point is on the graph

A medical school claims that more than 28% of its students plan to go into general practice. To test this claim, a random sample of 130 of the school's students is selected. Of these, 32% of them plan to go into general practice. Find the P-value for this test of the school's claim.
Answer:
The p-value of the test is 0.1314.
Step-by-step explanation:
In this case we need to test the claim made by a medical school that more than 28% of its students plan to go into general practice.
The hypothesis can be defined as follows:
H₀: The proportion of students planning to go to general practice is 28%, i.e. p = 0.28.
Hₐ: The proportion of students planning to go to general practice is more than 28%, i.e. p > 0.28.
The information provided is:
n = 130
[tex]\hat p=0.32[/tex]
Compute the test statistic value as follows:
[tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]=\frac{0.32-0.28}{\sqrt{\frac{0.28(1-0.28)}{130}}}\\\\=1.12[/tex]
The test statistic value is 1.12.
Compute the p-value as follows:
[tex]p-value=P(Z>1.12)\\[/tex]
[tex]=1-P(Z<1.12)\\\\=1-0.86864\\\\=0.13136\\\\\approx 0.1314[/tex]
The p-value of the test is 0.1314.

[tex]f( - 4) = 3( - 4) - 8[/tex]
[tex]f( - 4) = - 20[/tex]
Answer:
Step-by-step explanation:
f(x) = 3x - 8
f(-4) = 3*(-4) - 8
f(-4) = -12 - 8
f(-4) = - 20
-20 is what goes in the box.

Answer:
circumference = 150.72cm
area = 1808.64cm²
Step-by-step explanation:
the formula for circumference = 2πr
the formula for area = πr²
24cm is the radius (r)
so therefore
circumference = 2(3.14)(24)
= 150.72cm
area = (3.14)(24)²
= 1808.64cm
im not too great at math- but I think this is correct ^^
