The answer is 6/7 or 5/6 idk but pic would help
Answer:
It is 14.45 percent
.
Step-by-step explanation:
Explanation:
The first day is independent from the day before. Therefore the first day probability (of rain) is 20 percent.
The second day (depends on the previous day) rainfall probability is 85 percent.
Finally, the third day (it must be rainy to satisfy the total probability) rainfall probability is 85 percent.
The probability of having three consecutive days which are rainy:
P(all rainy)
=
0.20
×
0.85
×
0.85
=
0.1445
or 14.45 percent.

Answer:
1: D
2: B
3: y=-4x+22
4: y=-8x+26
Step-by-step explanation:
1: Parallel lines have the same slope, and the only one with a slope of 3x is D
2: Perpendicular lines have an opposite slope, so a line with a slope of -1/2 would be 2, so you just flip the number and add or take away a negative sign, depending on the original slope
3: Like I said before, perpendicular lines have an opposite slope, so the slope would be -4. After you've figured that out, you just plug in the numbers given to you (and remember, x is first, y is last)
Plug in: 6=-4(4)+b
You would then solve for b.
6=-16+b
22=b
Then plug that into y=mx+b, with m being the slope (-4) and b being the y intercept (22)
4: The process for finding parallel and perpendicular lines is very similar, except you don't have to change the slope.
Plug in: 10=-8(2)-b
10=-16+b
26=b
Again, plug that into the equation y=mx+b
Hope I could be of help! Sorry if it doesn't make sense, this is my first time on this website.
