Step-by-step explanation:
Distribute to get 352+55x+4x-x
Combine like terms to get 352+58x.
Câu trả lời:
0,7
Giải thích từng bước:
Xác suất để một sự kiện xảy ra = 0,3
Cho sự kiện = A
P (A) = 0,3
Xác suất mà sự kiện không xảy ra có thể thu được bằng cách sử dụng quy tắc bổ sung;
P (A ') = 1 - P (A)
Vì thế,
P (A ') = 1 - 0,3 = 0,7
Answer/Step-by-step explanation:
✍️Slope of the line using two points, (2, 2) and (6, 10),

✍️To find the equation of the line in slope-intercept form, we need to find the y-intercept (b).
Substitute x = 2, y = 2, and m = 2 in y = mx + b, and solve for b.
2 = (2)(2) + b
2 = 4 + b
2 - 4 = b
-2 = b
b = -2
Substitute m = 2 and b = -2 in y = mx + b.
✅The equation would be:


✍️To find the value of a, plug in (a, 8) as (x, y) into the equation of the line.


Add 2 to both sides


Divide both sides by 2


a = 5
✍️To find the value of b, plug in (4, b) as (x, y) into the equation of the line.



Speed=distance/time
distance=205.296
time=3.12
speed=205.296/3.12=65.8
answer is 65.8 miles per hour
The x-value increases by a factor of 5 from 1.6 to 8 between the two points. Because the variation is inverse, the y-value must decrease by a factor of 5 between the two points.
6/5 = 1.2
The second point is (8, 1.2), corresponding to the 4th selection.
