Suppose that E and F are two events and that P(E)=0.2 and P(F|E)=0.5 What is P(E and F)?
By definition of conditional probability,
P(F | E ) = P(F and E ) / P(E )
Then
P(F and E ) = P(F | E ) P(E ) = 0.5 • 0.2 = 0.1

Find the solutions to the equation sqr3 sin x/2
+ cos x = 1 if 0º< < 360°. Check all that apply.
Edge 2020
Answer:
0 degrees
120 degrees
240 degrees
Step-by-step explanation:
The solutions to the equation √3sin(x/2) + cos(x) = 1, for 0º < x < 360°, are x = 0°, 120°, and 240°.
The given equation is √3sin(x/2) + cos(x) = 1.
Rearrange the equation to isolate the term with sin(x/2):
√3sin(x/2) = 1 - cos(x)
Square both sides of the equation to eliminate the square root:
3sin²(x/2) = (1 - cos(x))²
Apply the trigonometric identity sin²(x/2) = (1 - cos(x))/2:
3(1 - cos(x))/2 = (1 - cos(x))²
Multiply both sides by 2 to remove the fraction:
3(1 - cos(x)) = 2(1 - cos(x))²
Expand the square on the right side:
3 - 3cos(x) = 2(1 - 2cos(x) + cos²(x))
Simplify and rearrange the equation:
3 - 3cos(x) = 2 - 4cos(x) + 2cos²(x)
Combine like terms:
2cos²(x) - cos(x) - 1 = 0
Factor the quadratic equation:
(2cos(x) + 1)(cos(x) - 1) = 0
we can solve for x by setting each factor equal to zero:
2cos(x) + 1 = 0:
cos(x) = -1/2
x = 120°, 240° (in the range 0° < x < 360°)
cos(x) - 1 = 0:
cos(x) = 1
x = 0° (in the range 0° < x < 360°)

Ben drove 230 kilometers in 3 hours, and Pia drove 250
kilometers in 3 hours. Without making any calculations,
who drove faster? Explain how you know.
9514 1404 393
Answer:
Pia drove faster
Step-by-step explanation:
Speed is the ratio of distance to time. If the time is the same, the greater distance is associated with the greater speed.
Pia drove farther in 3 hours, so drove faster.
Answer:
Pia drove faster than Ben, because they drove for the same amount of time, but Pia traveled farther. Pia drove 20 more kilometers than Ben, but she and Ben drove for the same amount of time.

Graphically determine the slopes of the line segments that create triangle ACD shown below. Write your final slopes in simplest form.
Answer:
Step-by-step explanation:
From the graph attached,
Coordinates of points A, C and D are,
A(-2, -7), C(-6, 7) and D(9, 2)
Slope of AD = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{-7-2}{-2-9}[/tex]
= [tex]\frac{9}{11}[/tex]
Slope of CD = [tex]\frac{7-2}{-6-9}[/tex]
= [tex]-\frac{1}{3}[/tex]
Slope of AC = [tex]\frac{7-(-7)}{-6-(-2)}[/tex]
= [tex]-\frac{14}{4}[/tex]
= [tex]-\frac{7}{2}[/tex]
The slope of a line segment AD is 9/11, the slope of a line segment CD is -1/3, and the slope of a line segment AC is -7/2.
Given :
Graphically determine the slopes of the line segments that create triangle ACD shown below. Points -- C(-6,7), D(9,2), and A(-2,-7)a) The slope of a line segment AD is calculated as:
[tex]\rm m = \dfrac{2+7}{9+2}[/tex]
m = 9/11
b) The slope of a line segment CD is calculated as:
[tex]\rm m = \dfrac{2-7}{9+6}[/tex]
m = -1/3
c) The slope of a line segment AC is calculated as:
[tex]\rm m = \dfrac{7+7}{-6+2}[/tex]
m = -7/2

What is the slope and y intercept of the linear function graphed below? Answer slope as m = ______________; answer y intercept as b = ______________. *
Answer:
Slope (m) = -⁵/4
y-intercept (b) = 1.5
The graph is non-proportional
Step-by-step explanation:
The slope of a graph using the points, (-2, 4) and (2, -1) is calculated as:
[tex] m = \frac{y_2 - y_1}{x_2 -x_1} = \frac{-1 - 4}{2 -(-2)} = \frac{-5}{4} [/tex]
✅Slope (m) = -⁵/4
✅y-intercept (y) is the point at which the line intercepts the y-axis = 1.5
✅A proportional graph usually has a line that runs through the point of origin (0, 0). Therefore, the graph is non-proportional.
