Answer:
No mode
Step-by-step explanation:
There are no any numbers which are repeated. So there is no mode.
Answer:
The answer is C.no mode because the mode of a data set is the number that occurs most frequently in the set. To easily find the mode, but the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!
The number of booker borrowed from a library each week follows a normal distribution. When sample is taken for several weeks, the mean is found to be 190 and the standard deviation is 30
Answer:
2.5%
Step-by-step explanation:
Given :
Mean, μ = 190
Standard deviation, σ = 30
Probability that more than 250 books are borrowed ;
x = 250
P(Z > z)
Z = (x - μ) / σ
P[Z > (x - μ) / σ] = P[Z > (250 - 190) / 30]
P(Z > z) = P(Z > 2)
P(Z > 2) = 1 - P(Z < 2) = 1 - 0.97725
P(Z > 2) = 1 - P(Z < 2) = 0.02275
(0.02275 * 100)% = 2.275%
2.5% is closest to 2.275%

Step-by-step explanation:
With one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the entire batch is rejected if there is at least one defective unit. The ABCD Electronics Company has just manufactured 4500 write-rewrite CDs, and 150 are defective. If 4 of these CDs are randomly selected and tested, what is the probability that the entire batch will be rejected
Answer:
0.1269 = 12.69% probability that the entire batch will be rejected.
Step-by-step explanation:
CD's are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
4500 CDs, which means that [tex]N = 5000[/tex]
150 defective, which means that [tex]k = 150[/tex]
4 are selected, which means that [tex]n = 4[/tex]
What is the probability that the entire batch will be rejected?
At least 1 defective, which is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,4500,4,150) = \frac{C_{150,0}*C_{4350,4}}{C_{4500,4}} = 0.8731[/tex]
So
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.8731 = 0.1269[/tex]
0.1269 = 12.69% probability that the entire batch will be rejected.
Given the following information, give as complete a description of this figure as possible, including the measure of any sides and angles and any terms that can be used to describe the polygon.
Answer:
It's a square with four equal sides each side is 6cm. The angles at the four edges are all same have 90° between each two sides. You can calculate the area of the four triangles by using the formula 1/2 × hight × base. The hight will be 6 divided by 2 which is equal 3cm, and the base will be 6cm. So the area of each triangle is 1/2×3×6=9cm^2.

Answer:
x = 44.8
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj/ hyp
cos 48 = 30/x
x cos 48 = 30
x = 30 / cos 48
x=44.83429
Rounding to the nearest tenth

S is the centroid of the triangle. Find IT if ST =9
Answer:
27
Step-by-step explanation:
The centroid divide a median in two parts, with ratio 1/3 and 2/3.
In particular the part between the centroid and the point where the median touches the side is 1/3 of the median.
We can build this proportion:
ST : 1/3 = IT : 3/3
9 : 1/3 = IT : 1
IT = 9 * 3 = 27

Answer:
8[tex]\sqrt{3}[/tex]
Step-by-step explanation:
This is a special right triangle with angle measures 90-60-30 degrees
The side lengths are like the following :
The side length that sees 90 degrees is represented with x
The side length that sees 60 degrees is represented with x[tex]\sqrt{3}[/tex]
The side length that sees 30 degrees is represented with 2x
the side that sees 90 degrees is given as 16 so x = 8 and so a = 8[tex]\sqrt{3}[/tex]

A rectangular park of length 60 m breadth 50 m encloses w volleyball court of length 18 m and breadth 10 m. Find the area of the park excluding the court at the rate of Rs 110 per square meter.
Given
A rectangular park of length 60 m breadth 50 m encloses with volleyball court of length 18 m and breadth 10 m.
To find:
The area of the park excluding the court at the rate of Rs 110 per square meter.
Solution:
Area of a rectangle is:
[tex]Area=length \times breadth[/tex]
Area of whole park is:
[tex]A_1=60 \times 50[/tex]
[tex]A_1=3000[/tex]
Area of volleyball court is:
[tex]A_2=18 \times 10[/tex]
[tex]A_2=180[/tex]
Now, the area of the park excluding the court is:
[tex]A=A_1-A_2[/tex]
[tex]A=3000-180[/tex]
[tex]A=2820[/tex]
Therefore, the area of the park excluding the court is 2820 square meter.
here are the first five terms of a quadratic sequence (1 8, 21, 40, 65). the nth term of this sequence can be written in the form (an2 + bn). where a and b are integers. work out the value of a and the value of b
Answer:
a=3 and b=-2
Step-by-step explanation:
We are given that five terms of a quadratic sequence are
1 8, 21, 40, 65.
The nth term of this sequence
=[tex]an^2+bn[/tex]
We have to find the value of a and b where a and b are integers.
For n=1
[tex]a+b=1[/tex] ......(1)
For n=2
[tex](2)^2a+2b=8[/tex]
[tex]4a+2b=8[/tex]
[tex]2a+b=4[/tex] .....(2)
Subtract equation (1) from (2) we get
[tex]2a-a=4-1=3[/tex]
[tex]a=3[/tex]
Using the value of a=3 in equation (1)
[tex]3+b=1[/tex]
[tex]b=1-3=-2[/tex]
Hence, the value of
a=3 and b=-2

The area of a triangle is one-half times the base times the height. If the area of a
triangle is 54 sq. in, and its height is 12 in., what is the base????
I rlly need answer haha
Answer:
The base is 90 sq
Step-by-step explanation:
Formula for Area= 1/2*b*h
where b is unknown and area = 54sq
Placing in formula1/2 *b*12 = 54sq
12b = 54*2
12b /12 = 54*2/12
b = 9sq

Answer:
Definition of Bisect
Step-by-step explanation:
By definition, when two lines bisect each other, they divide each other into two equal segments.
In statement 2, we see that PO and ON are being labelled as congruent, which is referring back to the given information that MQ bisects PN. Since PO and ON are the two segments bisected by MQ, the two must be congruent simply from the definition of bisect.

¿Cuál es interés simple generado en un plazo fijo, por una capital de $10.000.000, al 4% bimestral durante 4 años?
Answer:
S.I = $1,608,000
Step-by-step explanation:
Given the following data;
Principal = $10.000.000Interest rate = 4%Time = 4 yearsTo find the simple interest, we would use the formula;
S.I = PRT
Where;
S.I is the simple interest.P is the principal.R is the interest rate.T is the time.Since the interest is being paid every two months (six times a year), the 4% interest will be divided by 6.
Thus: 4% every two months = [tex] 4 * \frac {2}{12} [/tex] = [tex] \frac {8}{12} [/tex] = 0.67% = 0.0067
4 years = 4 * 6 = 24 two-month years.
Substituting the values into the formula, we have;
S.I = 10.000.000 * 0.0067 * 24
S.I = $1,608,000

Suppose x(t) is the continuous-time function given by x(t) = 1 on the interval [0; 1] and x(t) = 0 elsewhere. a) Calculate the continuous time Fourier transform of x(t). Call this X(j????). b) Suppose x1 (t) = x(2t). Provide the explicit definition for x1 (t) (i.e. over what interval
Answer:
a) X( w ) = 1 /jw - e^-jw / jw
b) X1(t) = 1 for 0.5
X1(t) = 0 for elsewhere
Step-by-step explanation:
x(t) continuous time function = 1
interval ( 0,1 ) also x(t) = 0 outside the given interval
a) Determine the continuous time Fourier transformation of x(t)
x( t ) = u(t) - u(t - 1 )
x ( w ) = 1 /jw - e^-jw / jw
b) supposing x1(t) = x(2t)
x1(t) = u(t) - u ( t - 0.5 )
x1(t) = 1 for 0.5
x1(t) = 0 for elsewhere
