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))

Given:
The two triangles are similar by SSS.
To find:
The value of x.
Solution:
If two triangles are similar to each other by SSS, then the corresponding sides of the triangles are proportional.
It is given that [tex]\Delta ABC\sim \Delta DE F[/tex]. So,
[tex]\dfrac{AB}{DE}=\dfrac{BC}{EF}=\dfrac{AC}{DF}[/tex]
[tex]\dfrac{9}{6}=\dfrac{12}{8}=\dfrac{3(x-1)}{x+1}[/tex]
[tex]\dfrac{3}{2}=\dfrac{3}{2}=\dfrac{3x-3}{x+1}[/tex]
[tex]\dfrac{3}{2}=\dfrac{3x-3}{x+1}[/tex]
On cross multiplication, we get
[tex]3(x+1)=2(3x-3)[/tex]
[tex]3x+3=6x-6[/tex]
[tex]3x-6x=-3-6[/tex]
[tex]-3x=-9[/tex]
Divide both sides by -3.
[tex]x=3[/tex]
Therefore, the value of x is 3.

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 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

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
Answer:
Red line has higher intercept and slope.
The equation for the line: y= 0.5x

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.

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

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.
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.

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
