Find the sum of the arithmetic sequence 22, 11, 0, -11, ..., –77.
A -198
B.-275
C. -297
D. -385
Answer:
B.
Step-by-step explanation:
First you need to figure out how many numbers there are, so with this you can simply count 10. Then use the formula to plug in the numbers: 10(22-77)/2 to get the answer.
The required sum of the arithmetic progression is -275.
The arithmetic sequence is given 22, 11, 0, -11, ..., –77, sum of the sequence is to be determined.
Arithmetic progression is the series of numbers that have common differences between adjacent values
Here,
first term (a) = 22
Last term (l) = -77
Now,
l = a + (n - 1)d
-77 = 22 + (n - 1) *(-11)
-77 - 22 = (n - 1)(-11)
n - 1 = 9
n = 10
Now,
sum of the arithmetic sequence,
s = n / 2 [a + l]
s = 10 / 2 [22 - 77]
s = 5 [-55]
s = -275
Thus, the required sum of the arithmetic progression is -275.

What is 24:28=? 250:400=? 270:30=? 4:80=? 55:33=? 1000:100=? 560:80=? 20:340=?
Plz help ill give u 20 points if u do all of these:)
Step-by-step explanation:
Ok so if you didn't know, : is another way to write / so 24:28 is the same thing as 24 divided by 28. Or if you just wanted to simplify to most, you just want to find the largest common factor and divide it by both.
24:28 = 6:7
250:400 = 5:8
270:30 = 9:1
4:80 = 1:20
55:33 = 5:3
1000:100 = 100:10
560:80 = 7:1
20:340 = 1:17
Answer: 24:28= 6:7
250:400= 5:8
4:80= 1:20
55:33= 5/3
1000:100= 10:1
560:80= 7:1
20:340= 1:17
Step-by-step explanation:
Divide the numbers on each side of the ratio by Common Factors until what's left can't be divided any further.
One example, last one:
20:340 both divisible by 10, so you get 2:34. Both even numbers so divide by 2. You get 1:17. They can't be divided any further to get whole numbers, so that's the answer.

Chase drew a scale drawing of a community college. A building at the college, which is 260 meters long in real life, is 286 millimeters long in the drawing. what scale did chase use?
Given parameters:
Actual length = 260m
Drawing length = 286mm
Unknown:
Scale used = ?
Solution:
A scale compares drawing length to ground distance;
To find the scale,
Express the two quantities in the same unit;
actual length = 260 x 10⁻³m = 0.26mm
Now;
drawing length : actual length
286mm : 260 x 10⁻³mm
divide by 286;
1mm on drawing : 9 x 10⁻⁴mm on map
or;
1mm on drawing is 0.9m on ground

Step-by-step explanation:
Given :[tex] \sf{A} \: = \: [/tex] { -6 , 0 , 6 }
[tex] \sf{B} \: = [/tex]{ -1 , 0 , 1 }
To find :A ∩ B
Solution :A ∩ B = { -6 , 0 , 6 } { -1 , 0 , 1 }
A ∩ B = { 0 }
Remember : In case of intersection , the common element of two sets A and B should be listed in a single set. So, the intersection of sets A and B is the set of all elements which belong to both A and B. The intersection of sets A and B is denoted by ( A ∩ B ) and read as A intersection B.

In a study of the television viewing habits of children, a developmental psychologist selects a random sample of 300 first graders - 100 boys and 200 girls. Each child is asked which of the following TV programs they like best: The Lone Ranger, Sesame Street, or the Simpsons.
Complete the following table:
Answer:
20, 50, 70, 110
Step-by-step explanation:
boys x simpsons: 20
girls x long ranger: 50
girls x simpsons: 70
total x sesame street: 110
have a great day :)
20 girls watch Long Ranger , 110 first graders watch Sesame Street , 20 boys watch Simpsons, and 70 girls watch Simpsons.
What is random sampling?" Random sampling is a process of observing samples using such technique that each sample has equal probability."
According to the question,
As per the information of random samples given in the table,
Total number of boys are = 100
Total number of girls = 200
For boys
Long Ranger + Sesame Street + Simpsons = 100
⇒ 50 + 30 + Simpsons = 100
⇒ Number of boys view Simpsons = 100 - 80
= 20
In Long ranger column,
50 Boys + ___girls = 100
⇒ Number of girls watching Long Ranger = 100 -50
= 50
In Sesame street
30 boys + 80 girls = 110 Total viewers
Number of girls watching Simpsons = 90 -20
= 70
Hence, 20 girls watch Long Ranger , 110 total boys and girls watch Sesame Street , 20 boys watch Simpsons, and 70 girls watch Simpsons.
