The idea is to find the sum of integers between 1 and 100 using the n×(n+1)/2 where n is the array’s size and subtract the actual sum of array
What is Python used for?Python is a popular computer programming language used to create software and websites, automate processes, and analyze data. Since Python is a general-purpose language, it may be used to develop a wide range of applications and isn't tailored for any particular issues.
Python code for computing sum
Find the missing number in a given array
def getMissingNumber(arr):
# get the array's length
n = len(arr)
# actual size is `n+1` since a number is missing from the list
m = n + 1
# get a sum of integers between 1 and n+1
total = m * (m + 1) // 2
# the missing number is the difference between the expected sum and
# the actual sum of integers in the list
return total - sum(arr)
if __name__ == '__main__':
array_input = input("Enter a list of integers separated by spaces: ")
array = [int(x) for x in array_input.split()]
print('The missing number is', getMissingNumber(arr))

Event A: Rolling a number less than 4 on a number cube Event B: Flipping heads on a coin toss What is the probability of A, the probability of B, and the probability of both A and B?
P(A) =
P(B) =
P(A and B) =
Answer:
first one is 1/2
the next one is 1/2
the last one is 1/4
Step-by-step explanation:
i just did it
The probability of A will be P(A) = 1/2. The probability of B will be P(B) = 1/2. The probability of A and B will be P(A and B) = 1/4
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
Event A: Rolling a number less than 4 on a number cube.
Event B: Flipping heads on a coin toss
We need to find the probability of A, the probability of B, and the probability of both A and B.
The probability of A will be
P(A) = 1/2
The probability of B will be
P(B) = 1/2
The probability of A and B will be
P(A and B) = 1/2 x 1/2
P(A and B) = 1/4

The radius of a circle is 11 in. Find its circumference in terms of \piπ.
Answer: C=
Answer:
C = 22cm
Step-by-step explanation:
If the radius equals to 11, then the diameter is 22 since the diameter is double of radius. They told us to use π, so the answer is 22π.
Write the point-slope form of an equation of the line through the points (-2, -3) and (-7, 4).
A. y+2=−75(x+3)
B. y−4=−75(x−7)
C. y+3=−75(x+2)
D. y+7=−75(x−4)
Answer:
458435464546484845kdnh
Answer:
C. y+3=−7/5(x+2)
Step-by-step explanation:
Line is passing through the points (-2, -3) and (-7, 4).
Slope of line = (-3 - 4)/[-2-(-7)]= (-7)/(-2+7) = - 7/5
Equation of line in the point-slope form is given as with point (-2, -3).
y - (-3) = - 7/5[x - (-2)]
y + 3 = - 7/5(x +2)

Given:
The height of 44 students (in centimeter) are presented in the given frequency distribution.
To find:
The median of the given data.
Solution:
The given intervals are inclusive first make the intervals exclusive by adding 0.5 in upper limit and by subtracting 0.5 from the lower limit.
The complete frequency distribution table is shown below:
Height Frequency L <cf
182 - 188 1 181.5 - 188.5 44
175 - 181 3 174.5 - 181.5 43
168 - 174 6 167.5 - 174.5 40
161 - 167 15 160.5 - 167.5 34 Median class
154 - 160 12 153.5 - 160.5 19
147 - 153 4 146.5 - 153.5 7
140 - 146 3 139.5 - 146.5 3
We have, [tex]n=44[/tex].
[tex]\dfrac{n}{2}=\dfrac{44}{2}[/tex]
[tex]\dfrac{n}{2}=22[/tex]
The 22th term is include in the class 160.5 - 167.5 because is cf is greater than 22 but the cf of o preceding class is less than 22. So, it is the median class is 160.5 - 167.5.
Formula for median:
[tex]Median=l+\dfrac{\dfrac{n}{2}-cf}{f}\times h[/tex]
Where, l is the lower limit of median class, cf is the cumulative frequency of preceding class, f is the frequency of median class and h is the size of the class.
Now, [tex]l=160.5,f=15,cf=19,h=7[/tex].
[tex]Median=160.5+\dfrac{22-19}{15}\times 7[/tex]
[tex]Median=160.5+\dfrac{3}{15}\times 7[/tex]
[tex]Median=160.5+1.4[/tex]
[tex]Median=161.9[/tex]
Therefore, the median of the given data table is 161.9.

Step-by-step explanation:
What is the image point of (-5,0) after a translation left 2 units and down 1 unit?
Answer:
The image point of (-5, 0) after a translation left 2 units and down 1 unit would be the point (-7, -1).
Step-by-step explanation:
The original point is located at (-5, 0), a translation of two units to the left would be an increase of -2 in the x-axis, and a translation of down 1 unit would be an increase of -1 in the y-axis. Using the translation, you can infer that the new coordinate would be (-5 - 2, 0 - 1) or (-7, -1).

In ADEF, what is sin D, in simplified form?
Answer:
In simplified form, sin D is;
4/5
Step-by-step explanation:
The given figure and dimension parameters in the question are;
Triangle ΔDEF is a right triangle
The length of leg [tex]\overline{EF}[/tex] which is opposite side to the reference angle = 20
The length of segment [tex]\overline{ED}[/tex] which is the hypotenuse side of the right triangle ΔDEF = 25
The length of segment [tex]\overline{DF}[/tex] which is adjacent side to the reference angle = 15
By trigonometric ratios, we have;
[tex]sin\angle X = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]
Therefore, we have;
[tex]sin\angle D = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length} = \dfrac{20}{25} = \dfrac{4}{5}[/tex]
∴ In simplified form, sin(D) = 4/5.
FREE BRAINLIEST TO WHOEVER ANSWERS CORRECT FIRST! A movie company conducts a survey using a representative sample of customers to determine their favorite type of movie. The results are shown below. Based on the survey results, how many customers are expected to prefer drama movies out of 2,500 customers?
Favorite Movie Types
.
Answer:
320 customers
Step-by-step explanation:
Well the chart given is a huge ratio since its a sample.
you would have this ratio
41:25:43:16
You can add them all up since then you would know how much people have actually be chosen for the survey.
You’d get 125. So 125 is the sample out of 2500 so we can divide to see how much of these “125” samples are in 2500.
You’d get 20.
So there are 20 “125” samples and we’re only focusing on drama which is 16 out of 125. 20*16 would be 320.

Answer:
a) Line M
b)Line M
c)y=1/2x+2
Step-by-step explanation:
a) Line M has a greater y-intercept since its y-intercept is at (0,2) while Line N's y-intercept is at (0,1)
b) Line M has a greater slope since its line is steeper
c) Use the formula y=mx+b
Use the points ( 0,1) and (-4,-1)
m(slope)= y2-y1/x2-x1
m= (-1-1)/(-4-0)
m=-2/-4
m=1/2
substitute
(0)=1/2(-4)+b
2=b(y-intercept)
y=1/2x+2

The number magazines you can buy with $9.00 is 3.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, at Nivea's Newsstand, 6 magazines cost $18.00.
Cost of 1 magazine is 18/6
=$3
Number of magazine with $9 is 9/3

In a survey of 232 students, about 5.5% have attended more than one play. Which is closest to the number of students in the survey who have attended more than play? 5 7 13 16
Answer:
13
Step-by-step explanation:
Number of students that attended more than play = percentage of students that attended more than play x total number of students
5.5% x 232
0.055 x 232 = 12.76 students
to round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.
Since the first term is 7 which is greater than 5, 1 would be added to it.
This gives 13
