QUESTION 3 Let G and H be two events in a sample space. P(G) = 0.4, P(H) = x and P(G or H) = 0.7 3.1 For what value of x are G and H mutually exclusive? (2)
For x = 0.33, the events G and H are mutually exclusive.
Here, we are given that-
P(G) = 0.4
P(H) = x
and P(G or H) = 0.73
⇒ P(G∪H) = 0.73
Now, we know that-
P(G U H) = P(G) + P(H) - P(G ∩ H)
For any two events that are mutually exclusive, the probability that they occur at the same time is 0. Hence, if G and H are mutually exclusive, then P(G ∩ H) will be 0
⇒ 0.73 = 0.4 + x - 0
x = 0.73 - 0.4
x = 0.33
Thus, for x = 0.33, the events G and H are mutually exclusive.

Step-by-step explanation:
Find the value of the trig function indicated.
In the given triangle, we have
[tex]\tan(\theta) = \dfrac{20}{15} = \dfrac43[/tex]
Recall that
[tex]\sin^2(\theta) + \cos^2(\theta) = 1 \implies \tan^2(\theta) + 1 = \sec^2(\theta)[/tex]
Solving for [tex]\sec(\theta)[/tex], we have

mean=6.4
standard deviation=0.6
we have to find the range in which at least 75% of the data will reside
1-1/k²=0.75
1/k²=1-0.75
1/k²=0.25
k²=1/0.25=4
k=2
so, k=2
The range of values can be computed as mean±k(standard deviation).
Thus, the range in which at least 75% of the data will reside is

BD bisects angle ABC. Solve for x and find m angle ABC.
m angle ABD = 6x-8, m angle CBD = 3x + 4
Answer:
The value of x = 4
so
m ∠ABD = 6x-8 = 6(4)-8 = 24-8 = 16m∠CBD = 3x+4 = 3(4)+4 = 12+4 = 16Step-by-step explanation:
We know that an angle bisector bisects the angle into two equivalent angles.
When BD bisects angle ABC, it forms two equivalent angles which are:
m∠ABDm∠CBDsuch as
m∠ABD = m∠CBD
as
m ∠ABD = 6x-8
m∠CBD = 3x+4
so the equation becomes
m∠ABD = m∠CBD
6x-8 = 3x+4
6x - 3x = 4 + 8
3x = 12
Divide both sides by 3
x = 4
Thus, the value of x = 4
so
m ∠ABD = 6x-8 = 6(4)-8 = 24-8 = 16m∠CBD = 3x+4 = 3(4)+4 = 12+4 = 16Robert bought two movie tickets for $10. Deion spent $20 on 4 movie tickets.

Takis Tortilla Chips Variety Pack 18 Count
what is the unit rate of the product
Answer:
About 42 cents
Step-by-step explanation:
What we know:
An 18-count variety pack of Taki's chips costs $7.49.
To find the unit rate divide 7.49 by 18, and round to the nearest cent.
7.49/18
Before we do that, what is 749/18?
749/18 = 41 11/18
Divide that by 100 to get your answer
41.61111/100 = 0.4161111, which rounds to 42 cents.

Find the diameter of this circle.
A. [tex]2\sqrt{10}[/tex]
B. [tex]4\sqrt{10}[/tex]
C. 8
D. [tex]2\sqrt{34}[/tex]
Answer:
A
Step-by-step explanation:
From looking at the graph, you can see that the center point of the circle is at (5, -3), so to figure out the diameter, you need to find the distance of that line ( y = - 3 ) that the circle is on. The diameter is about 6 point something which in the square root form can be represented by √36.
After knowing the diameter is about 6, choice C can be eliminated.
2√10 = √40
4√10 = √160
2√34 = √136
After expanding the square root, we can know that the closest option is A.
Check the picture below.
so we know the circle has that center and passes through (2 , -2), let's find its radius, keeping in mind that diameter = 2 * radius.

Answer:
10.75 psiStep-by-step explanation:
Let the equation be:
y = kx, where y- pressure, k- constant, x - depthFor the depth of 20 ft, the equation is:
8.6 = 20kk = 8.6/20k = 0.43For the depth of 25 ft, the pressure is:

The answer is y=-5/3x+1 because you would do the exact opposite of rise over run where it rises 5 units up and 3 units shifted right but instead it is still 3 units that are shifted to the right but 5 units down. We can also assume that the y-intercept is 1 based on where the slope is placed.

What is complex number?"It is combination of a real number and an imaginary number.""The complex number is of the form of a + ib, where a, b are real numbers and i = [tex]\sqrt{-1}[/tex]"How to write complex number in trigonometric form?For a complex number z = a + ib, the trigonometric form is [tex]r(cos\theta +isin\theta)[/tex]
where [tex]r=|\sqrt{a^{2} +b^{2} } |[/tex] and [tex]\theta=tan^{-1}(\frac{b}{a} )[/tex]
For given question,
We need to find the cube root of -8
[tex]\sqrt[3]{-8}[/tex]
We can write above number as complex number.
[tex]\sqrt[3]{-8}\\ =\sqrt[3]{8\times (-1)}\\ =\sqrt[3]{8}\times \sqrt[3]{-1}\\ =2 \times(-1)^\frac{1}{3}[/tex]
Consider a complex number z = -1
We can write -1 in trigonometric form as, [tex]-1=cos(\pi)+isin(\pi)[/tex]
We know, [tex](cos\theta +isin\theta)^{\frac{1}{n} }=(cos(\frac{1}{n} \theta )+isin(\frac{1}{n} \theta))[/tex]
So,
[tex](-1)^{\frac{1}{3} }\\\\=(cos\pi+i~sin\pi)^{\frac{1}{3} }\\\\=cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} )[/tex]
Therefore, an expression that represents a cube root of -8 is [tex]2(cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} ))[/tex]
