QUESTION: Caitlin likes to finish her homework as early as she can. The probability that she has a math homework tonight is 0.63 and the probability that she has science homework tonight is 0.22. If the probability that Caitlin had both math and science homework tonight is 0.13 then what is the probability that she has neither math homework nor science homework tonight?
GIVEN:
P(Math) = 0.63
P(Science) = 0.22
P(Math & Science) = 0.13
ASKED: P(Neither Math nor Science)
FORMULA: P(Neither Math nor Science) = 1 - P(Math or Science)
SOLUTION:
In order to find what is asked, we needed to find first the P(Math or Science).
P(Math or Science) = P(Math) + P(Science) - P(Math and Science)
P(Math or Science) = 0.63 +0.22 -0.13
P(Math or Science) = 0.72
Next, we should substitute the value we got to the formula given above.
P(Neither Math nor Science) = 1 - P(Math or Science)
P(Neither Math nor Science) = 1 - 0.72
P(Neither Math nor Science) = 0.28
ANSWER: The probability that Caitlin has neither Math homework nor Science homework is 0.28. In the choices, it is the letter C.

from a careful observation, one would notice that line VS is the diameter of the circle and ut is the lenght of an arc. however, we have to find the angle UT
[tex]\begin{gathered} vs=180^0 \\ vs=vr+sr \\ vr=127^0 \\ 180=127+sr \\ sr=180-127 \\ sr=53^0 \end{gathered}[/tex]note: vs is equal to 180 degrees because angle on a straight line is equal to 180 degree
[tex]\begin{gathered} ur=180^0 \\ ur=uv+vr \\ 180=uv+127 \\ uv=180-127 \\ uv=53^0 \end{gathered}[/tex]now we can solve for angle UT easily

what is an approximate solution of the system of equations? y=-0.5x+4 y=1+2x1.25,3.42.25,3.43.4,2.253.4,1.25
Combining the two equations gives us
[tex]-0.5x+4=2x+1[/tex]We add 0.5x to both sides and get
[tex]4=2.5x+1[/tex]and subtracting 1 from both sides gives
[tex]2.5x=3[/tex]And finally, dividing both sides by 2.5 gives
[tex]x=1.2[/tex]Putting this value of x into y = 2x + 1 gives
[tex]y=2(1.2)+1[/tex][tex]y=3.4[/tex]Hence our solution is
[tex]\textcolor{#FF7968}{(1.2,3.4)}[/tex]Solve for y4(2Y - 2) = 7(y + 5)
Answer:
y = 43
Explanation:
To solve for y, we will apply the distributive property as:
[tex]\begin{gathered} 4(2y-2)=7(y+5) \\ (4\cdot2y)-(4\cdot2)=(7\cdot y)+(7\cdot5) \\ 8y-8=7y+35 \end{gathered}[/tex]So, subtracting 7y from both sides:
[tex]\begin{gathered} 8y-8-7y=7y+35-7y \\ y-8=35 \end{gathered}[/tex]Adding 8 to both sides:
[tex]\begin{gathered} y-8+8=35+8 \\ y=43 \end{gathered}[/tex]Therefore, the answer is y = 43

[tex]\begin{gathered} n^6\cdot n^5\frac{\cdot}{\cdot}n^4\cdot n^3\frac{\cdot}{\cdot}n^2\cdot n=n^{11}\frac{\cdot}{\cdot}n^4\cdot n^3\frac{\cdot}{\cdot}n^2\cdot n^{} \\ =n^7\cdot n^3\frac{\cdot}{\cdot}n^2\cdot n=n^{10}\frac{\cdot}{\cdot}n^2\cdot n=n^8\cdot n=n^9 \end{gathered}[/tex]therefore, the simplified expression is n^9
One linear equation is defined by the points (2,4) and (1,1), while the other is defined by the points (2,-2) and (-1,-5). Which point represents the solutions to this system of equations?
Explanation:
one linear equation points: (2,4) and (1,1)
the 2nd equation points: (2,-2) and (-1,-5)
we find the equation of line of both
equation of line: y = mx + c
m = slope, c = intercept
[tex]m\text{ = }\frac{y_2-y_1}{x_2-x_1}[/tex]for the 1st one: (2,4) and (1,1)
m = (1-4)/(1-2) = -3/-1
m = 3
To get c, we use the slope and any point. Using point (2,4):
4 = 3(2) + c
4 = 6 + c
c = 4-6
c = -2
The equation of the line: y = 3x - 2

Answer:
For x = -5: -16
For x = 9: √5
Explanation:
The function is given by
f(x) = √(x - 4) when x ≥ 4 and
f(x) = 2x - 6 when x < 4
Since -5 is lower than 4, we need to use f(x) = 2x - 6 to evaluate f(x) for x = -5. So, replacing x by -5, we get:
f(x) = 2x - 6
f(-5) = 2(-5) - 6
f(-5) = -10 - 6
f(-5) = -16
On the other hand, 9 is greater than 4, so we will use the function f(x) = √(x - 4). Then, replacing x = 9, we get
f(x) = √(x - 4)
f(9) = √(9 - 4)
f(9) = √5
Therefore, the answers are
For x = -5: -16
For x = 9: √5

[tex](2x^5+7x^3)-(5x^2-4x^3)=2x^5+7x^3+4x^3-5x^2[/tex][tex](2x^5+7x^3)-(5x^2-4x^3)=2x^5+11x^3-5x^2[/tex]Final answer:
[tex]2x^5+11x^3-5x^2[/tex]what is -6(w-4)+8w=2(w+9)
Answer:
Explanation:
The equation
[tex]-6(w-4)+8w=2(w+9)[/tex]can be solved for w by first expanding both sides
Now,
[tex]-6(w-4)+8w=2w+24[/tex]and
[tex]2(w+9)=2w+18[/tex]therefore, our equation becomes
[tex]2w+24=2w+18[/tex]Subtracting 2w from both sides gives
[tex]24=18[/tex]We see a contradiction here. 24 is not equal to 18; therefore, the equation given has no solutions.

Given the relation between x and t :
where: x is the position from the origin and t is the seconds
[tex]x(t)=t^3-2t^2+4t[/tex]a. On the interval 0< t <4, find when the particle is farthest to the right.
There are two methods to find the answer : by graph or by derivatives
So, we will use derivatives to find the answer
[tex]x^{\prime}(t)=3t^2-4t+4[/tex]so, at the farthest point the speed = 0
The solution of the equation will be imaginary solutions
Which mean distance will always increase
So, the farthest point will be at t = 4
So, the farthest =
[tex]x(4)=4^3-2\cdot4^2+4\cdot4=64-32+16=48\operatorname{cm}[/tex]b. On the same interval, what is the maximum speed?
The speed is given by x'(t)
So, at the same interval , the speed will be maximum at t = 4
so,
[tex]\begin{gathered} x^{\prime}(t)=3t^2-4t+4 \\ \\ x^{\prime}(4)=3\cdot4^2-4\cdot4+4=3\cdot16-16+4 \\ x^{\prime}(4)=36\text{ cm/sec} \end{gathered}[/tex]Also, see the following figure which represents the graph solutions:
The position equation is the blue curve
The speed equation is the violate curve

Bree is climbing a mountain. She knows that the faster she climbs, the less time the climb will take.
We know that the faster she climbs, the less time the climb will take.
As you can observe, the given relationship is between her speed and the height of the climb. We can deduct that this situation can be modeled by the speed in function of the time.
However, let's analyze each answer choice.
Choice A can't be right because the height of the mountain is not variable, that is, the mountain won't change its height.
Choice B is relating time and speed which, as we said before, the situation involves a relationship between time and speed.
Therefore, the right answer is B.Select all the expressions that are equal to: 8x +3+5x-2x

what is y intercept (0.2)(6,0)
The y intercept of the equation of the line passing from points (0,2) and (6,0) is 2.
What is meant by the term y intercept?The point at which the graph intersects this same y-axis is known as the y-intercept. Finding the intercepts of any function of the form y = f(x) is critical when graphing. A function can have one of two types of intercepts. They are known as the x and y intercepts.For the given question;
The coordinates of the line are,
(x1, y1) = (6,0)
(x2, y2) =(0,2)
Slope = m = (y2 - y1)/(x2 - x1)
m = (2 - 0)/(0 - 6)
m = -2/6 = -1/3
The equation of line will be;
y - y1 = m(x - x1)
y - 0 =(-1/3)(x - 6)
y = -x/3 + 2
Where slope is (-1/3) and y intercept is 2.
Thus, the y intercept of the equation of the line passing from points (0,2) and (6,0) is 2.
