the probability it is windy, given that it is raining = p(w|r)=p(wπr)/p(r) =0.3/0.7 =3/7= 0.429
the probability it is raining, given that it is windy.
p(r|w)=p(wπr)/p(w) =0.3/0.5 =3/5 = 0.6

Answer:
-2, 0
Step-by-step explanation:
The solution(s) to f(x) = g(x) are the x-coordinates of the points where the graphs intersect. The points of intersection of these graphs are ...
(-2, 0) and (0, 4)
The x-coordinates of these points are -2 and 0.
The solutions to f(x) = g(x) are x=-2 and x=0.

A cylinder has radius 2.5 meters. its volume is 50pi meters. Find its height.
Answer :
8 meters .⠀
Explanation :
The volume of the cylinder is 50π cubic meters.The cylinder has radius 2.5 meters.⠀
To Find :
The height of the cylinder.⠀
Solution :
⠀
We know,
[tex]{ \longrightarrow\qquad \bf\pi {r}^{2}h = \bf{Volume_{(cylinder) } }}[/tex]
⠀
Where,
r is the radius of the cylinder.h is the height of the cylinder.⠀
Now, Substituting the values :
[tex]{ \longrightarrow\qquad \sf\pi \times {(2.5)}^{2} \times h = {50 \pi } }[/tex]
[tex]{ \longrightarrow\qquad \sf\pi \times 6.25 \times h = {50 \pi } }[/tex]
⠀
Cancelling π from both sides :
[tex]{ \longrightarrow\qquad \sf \cancel\pi \times 6.25 \times h = {50 \: \cancel \pi } }[/tex]
[tex]{ \longrightarrow\qquad \sf 6.25 \times h = {50 } }[/tex]
[tex]{ \longrightarrow\qquad \sf h = { \dfrac{50}{6.25} } }[/tex]
[tex]{ \longrightarrow\qquad {\pmb {\bf{h = {8 } }}}}[/tex]
⠀
Therefore,
The height of the cylinder is 8 meters .John 450 words in half an hour. How many words would he type in 7 minutes?

A triangle has an angle measuring 90°, an angle measuring 20°, and a side that is 6 units long. The 6-unit side is in between the 90° and 20° angles.
How many unique triangles can you draw like this?
Answer:
One
Step-by-step explanation:
Since we have a 90° angle and a 20° angle, the last angle must be 70°.
180° - 90° - 20° = 70°
Now we also have the requirement of a 6-unit side between the 90° and 20° angles.
With all of these requirements, we can only draw one triangle like this since we have an angle, an angle, a required third angle, and a side.

keeping in mind that parallel lines have exactly the same slope, let's check for the slopes hmmm nope, they're not equal, so the lines are not parallel.
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slopes hmmm
[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{\cfrac{1}{4}} ~\hfill \stackrel{reciprocal}{\cfrac{4}{1}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{4}{1}\implies -4}}[/tex]
low and behold, Line 2 has a slope that is negative reciprocal to the slope of Line 1, thus, they're indeed perpendicular.

I do see D(4-1) and C(-3,4). The question asks what is the midpoint. That would be point M, with a coordinate of (0.5,1.5), which is derived from the average of the two points: x: (4-3)/2 = 0.5; y: (-1+4)/2) = 1.5
See the attached image for how the points relate to each other. I derived an equation for the point to illustrate where the midpoint, M, is situated.
=============================
Slope = Rise/Run
Rise: (-1 - 4) = -5
Run: (4 - (-3)) = 7

Elena drove a total of 203 miles last week. She drove 28 miles during the week to run errands and 35 miles each day to go to work and back. What equation can be used to find the number of days, d, that Elena drove to work last week?
Answer:
ok so the equation will be
35d+28=203
-28
35d=175
divide by 35
d=5
she drove to work 5 times

What is the ratio of rise to run between the points (-10, 9) and (6, 5)? A. B. 4 C. D. -4
The ratio of rise to run, which is the slope between the two points is: -1/4.
What is the Slope between Two Points?Slope = ratio of rise to run = change in y/change in x
Given the following points:
(-10, 9) and (6, 5)
Rise = (5 - 9) = -4
Run = (6 -(-10)) = 16
Ratio of rise to run = slope = -4/16 = -1/4.
Therefore, the ratio of rise to run, which is the slope between the two points is: -1/4.

Round your final answer to the nearest tenth.
Use the Pythagorean theorem
Answer
x=37.8
Step-by-step explanation:
According to Pythagoras theorem
AB = 21.5
BC = 13.1
AC = ?
AC²= AB²+BC²
x² =(21.5)²+(13.1)²
x² =462.25+967.21
x² =1429.46
x =√1429.46

Answer:
Step-by-step explanation:
Two angles form linear pair if they are adjacent angles and their non common arms are opposite rays.
Corresponding angles: When two parallel lines are intersected by the transversal, the angles formed on the matching corners of the same side of the transversal are called corresponding angles.
∠1 + ∠2 = 180° {Linear pair}
135 + ∠2 = 180
∠2 = 180 - 135
∠2 = 45°
∠6 = ∠2 {Corresponding angles}
∠6 = 45°

how many terms of the A.p 18,16,14 ... be taken so that their sum is zero?
Answer:
19 terms
Step-by-step explanation:
the sum to n terms of an AP is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
here a₁ = 18 and d = a₂ - a₁ = 16 - 18 = - 2, then solving for n
[tex]\frac{n}{2}[/tex] [ (2 × 18) - 2(n - 1) ] = 0 ( multiply both sides by 2 to clear the fraction )
n(36 - 2n + 2) = 0
n(38 - 2n) = 0 ← distribute parenthesis on left side by n
38n - 2n² = 0 ← factor out 2n from each term on the left
2n(19 - n) = 0
equate each factor to zero and solve for n
2n = 0 ⇒ n = 0
19 - n = 0 ⇒ n = 19
n > 0 , then number of terms is 19

X^2+16x+_=(x+_)^2 what are the missing digits?
Answer:
x^2+16x+64=(x+8)^2
Step-by-step explanation:
For the first spot you find the perfect square of the equation
This is found by doing (1/2 16)^2
1/2 16 = 8
8^2 = 64
The second spot is factoring, where you would put half of 16 or the square root of 64
1/2 16 = 8
root 64 = 8
