Answer:

Step-by-step explanation:

first, we find the slope

slope = (y2 - y1) / (x2 - x1)

(8,2)....x1 = 8 and y1 = 2

(7,1)....x2 = 7 and y2 = 1

now we sub

slope = (1 - 2) / (7 - 8) = -1/-1 = 1

y = mx + b

slope(m) = 1

use either of ur points...I will use (8,2)...x = 8 and y = 2

now we sub and find b, the y intercept

2 = 1(8) + b

2 = 8 + b

2 - 8 = b

-6 = b

so ur equation is : y = 1x - 6....or just y = x - 6 <===

sesenic [268]

Answer:

2000 players will complete the game with a perfect score.

Step-by-step explanation:

The testing phase tells us that \frac{1}{500} is the probability that a person will finish with a perfect score.

This means 1 out of 500 people will be able to finish with perfect score.

Now,

the game is given to 1,000,000 (1 million) people and how much do we expect to finish with perfect score?? Simple! It would be  \frac{1}{500}the of 1 million!

We do the calculation shown below:

\frac{1}{500}*1,000,000=2000

So, 2000 players will complete the game with a perfect score.

Q # 8 please helme to resolve
kondor19780726 [428]

Sequence 1,5,9,13,...

A(0) = 1 +4x0=1

A(1) =1 + 4x1 = 5

A(2) = 1+ 4x2= 9

A(3) = 1 +4x3=13

A(n)= 1+4n   A(n-1) = 1+4(n-1) =1+4n-4= - 3+4n

A(n) - A(n-1) = (1+4n) - (-3=4n) = 4

A(n) = A(n-1) +4; 29 is the answer

Please answer number 1 and 2.
zavuch27 [327]

1, a.) The two specific conjectures are in the first image.

1, b.) The two general conjectures are in the second image.

2, a.) Two specific conjectures for this pattern are:

  • The common difference between two consecutive terms is 3.
  • And the given difference is A.P.

2, b.) From our observation two general conjecture is that the given sequence is an arithmetic sequence and the common difference is 3.

For finding its nth term we can use the formula: a(n) = a + (n-1) x d.

2, c.) A formula for the given pattern is 5 + (n-1)3, where n is the number of the term.

20.) Marc had to walk to the grocery store which was exactly 50 meters from his house. So far he has walked exactly 21 meters. W
Sloan [31]

Marc has walked 42 % of the journey

<h3>How to calculate the percentage ? </h3>

The total miles is 50 meters

Marc has walked for 21 meters

The percentage he has walked can be calculated as follows

= 21/50 × 100

= 0.42 × 100

= 42

Hence the percentage of mile Marc walked is 42%
