2. There is a 50% chance that Elaine will be late to school, a 40% chance that she will be late to
school and eat breakfast, and a 60% chance that she will be late for school or eat breakfast. What
is the probability that Elaine will eat breakfast?
(1 Point)
30%
Ο Ο
40%
50%
Ο Ο
60%
Answer:
50%
Step-by-step explanation:
Given that:
P(late) = P(L) = 50% = 0.5
P(Eat) = P(E) =?
P(LnE) = 40% = 0.4
P(LuE) = 60% = 0.6
P(LuE) = P(L) + P(E) - P(LnE)
0.6 = 0.5 + x - 0.4
0.6 = 0.1 + x
0.6 - 0.1 = x
0.5 = x
P(E) = 0.5
0.5 * 100% = 50%

9). If m∠7 = 100°,
m∠3 = m∠7 = 100° [Since, ∠3 and ∠7 are alternate interior angles]
10). m∠7 = 95°
m∠6 + m∠7 = 180° [Consecutive interior angles]
m∠6 = 180° - m∠7
m∠6 = 180° - 95°
m∠6 = 85°
11. m∠1 = 120°
m∠1 = m∠5 = 120° [Alternate exterior angles]
12. m∠4 = 20°
Since, m∠4 = m∠6 = 20° [Vertically opposite angles]
And m∠6 + m∠7 = 180° [Consecutive interior angles]
20° + m∠7 = 180°
m∠7 = 160°
13. m∠3 = 140°
m∠3 + m∠6 = 180° [Linear pair of angles]
m∠6 = 180° - m∠3
= 180° - 140°
= 40°
m∠6 = m∠8 = 40° [Corresponding angles]
14. m∠4 = 30°
m∠4 + m∠1 = 180° [Consecutive exterior angles]
m∠1 = 180° - 30°
m∠1 = 150°
15. m∠4 = 40°
m∠4 = m∠2 = 40° [Corresponding angles]
16. m∠7 = 125°
m∠6 + m∠7 = 180° [Consecutive interior angles]
m∠6 = 180° - 125°
= 55°
m∠6 = m∠4 = 55° [Vertically opposite angles]
17. m∠1 + m∠3 = 230°
Since, m∠1 = m∠3 [Corresponding angles]
m∠3 + m∠3 = 230°
m∠3 = [tex]\frac{230}{2}[/tex]
= 115°
m∠3 + m∠6 = 180° [Linear pair of angles]
m∠6 = 180° - 115°
m∠6 = 65°

All side lengths in quadrilateral PQRS measure 6 units. A transformation maps
PQRS to P'Q'R'S'. All sides of P'Q'R'S' measure 3 units. Is the mapping isometric?
Explain.
An isometric transformation is a transformation that preserves the distance and angles between a pre-image and its image. Examples are: translation, reflection, rotation.
Answer:
No, the side lengths are not preserved.
This is a non isometric transformation.

A person who weighs 100 pounds on Earth weighs 16.5 pounds on the moon. If a boy weighs 60 pounds on Earth, how much does he weigh on the moon?
Answer:
The answer is 10 Pounds.
Step-by-step explanation:
You get 10 pounds because you divide your weight by 6 and 60 divided by 6 is 10.
Answer:
3.636363636
Step-by-step explanation:
Because that is 16.5 percent of 60, you can find this by dividing 60 by your percentage your trying to find of it, 16.5 in this case.

The perimeter of a rectangle is 80 cm. The width is 10 cm more than twice the length. What
is the length and width of this rectangle? P=2W+2L
Answer:
L=10cm , W=30cm
Step-by-step explanation:
First use the given that W=10+2*L
Use P=2W+2L=80, substitute W in the perimeter formula
2(10+2L)+2L=80 and solve for L,
20+4L+2L=80 isolate variable L and combine like terms,
6L=80-20,
L=10, so W=10+2*10=10+20=30

What is the length of segment AD ? How do you know ?
Line segment AD is 4cm. Because A is the center, any lines coming off the centerpoint are congruent. So if line AC is 4cm, then line AD has to be 4cm as well.
Comparing the two circles, the length of segment AD is 4 cm. On the first circle, the diameter is BAE is 8cm.
How to describe a circle?We should know that a circle is a figure in which all distances are equal from the center and the line from the center to the circumference is called radius.
The diameter is the line that passes through the center of the circle dividing the circle into two equal parts.
The given information are that the circles are the same
Diameter of the circles = 8cm
Radius = D/2= 8/2
Radius = 4 cm in each circle
Since the two circles shave the same diameter of 8cm and segments are different because the second has 3 segments while the first has 2 segments
The length of the segment AD = 4 because its from center to circumference that is radius
The first circle BAE is a diameter because it divides the circle into two equal halves
Therefore the length of segment AD is 4cm because it is a radius.
the diameter is BAE is 8cm.

There are 24 more students in the seventh grade class than the number g in the eighth grade class. The seventh grade class has 160 students. Write and solve an equation to find the number of students in the eighth grade class.
Answer:
y= 8th grade class,
y + 24 =160
subtract 24 from both sides
y=136
there are 136 students in the eight grade class
Step-by-step explanation:
Answer:
136 students
Step-by-step explanation:
7th grade= 160 students
8th grade= g students
g= 160-24
g= 136 students

I need help on this question, I can't seem to understand piecewise functions!! ITS SO HARD.
Answer:
[tex]f(x)\left \{ {{3x+1 if x\leq 0} \atop {-3x+1 if x>0}} \right.[/tex]
Step-by-step explanation:
So if we first graph the given equation, we'll see the graph I've attached below.
Remember that piecewise functions are functions that change based on the circumstances. I know that sounds super confusing, but it's actually really simple!
In this case, for example, we see the line increasing from -∞ to [tex]0[/tex], and then suddenly going downwards and decreasing. That's a good spot for us to notice because that indicates a change. We notice that the function looks different when [tex]x<0[/tex] or [tex]x>0[/tex]. If you break the function into those two parts, you see that they are just linear equations, but they're only visible when x is either greater than or less than 0.
Now that we notice this pattern, we can find the equation of the lines for both lines.
The points (-3,-8) and (-1,-2) are points on the first line, the one that increases (on the left). We can use those points to find the slope of the first line. Remember the slope equation:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Plug in your points:
[tex]m=\frac{-2-(-8)}{-1-(-3)}[/tex]
[tex]m=\frac{6}{2}[/tex]
[tex]m=3[/tex]
So, the slope of the first line is 3. The y-intercept, looking at the graph, is 1. The equation of the first line is [tex]y=3x+1[/tex]. We'll need this later.
Let's do the same thing for the second line. Just looking at the graph, we can see that this is the same exact line, just with a negative slope. So, the equation for the second line is [tex]y=-3x+1[/tex].
So now we can set up a piecewise function.
[tex]f(x)\left \{ {{3x+1} \atop {-3x+1}} \right.[/tex]
The two functions in the bracket are the two different functions used in this graph. Now we need to figure out where each function is effective. Well, they share a y-intercept. Remember that a true function cannot have two points with the same x value. So the first function is effective to the left of x=0, while the second is effective to the right of x=0. In other words, when [tex]x\leq 0[/tex], [tex]f(x)=3x+1[/tex]. But, when [tex]x>0[/tex], [tex]f(x)=-3x+1[/tex]. Now our piecewise function looks like this:
[tex]f(x)\left \{ {{3x+1 if x\leq 0} \atop {-3x+1 if x>0}} \right.[/tex]
And that is our piecewise function for the original function.
I know this is confusing, so please let me know if you have any questions! I hope this helps!
The perimeter of a rectangular picture frame is 62 inches. The length of the 1
frame is one more than twice its width. What are the length and the width
of the frame?
Answer- each width = 10, each length = 21
Explanation: from the question we know that L=2w + 1 and we also know that a rectangle has the perimeter of 62 when we plug it in the equation we will get 62= 2(2w+1+w) we will multiply the 2 now and we will get 62=4w+2+2w we will combine like terms and we will minus two from both sides ending up with 60=6w we will divide six from both sides and we will get w=10 then we will use l=2w+1 to find the length and it will be 21
