Determine whether the event below is mutually exclusive. Then find the probability. Round to the nearest tenth of a percent, if necessary. Rolling a pair of dice and doubles or a sum of 6 is rolled.Not mutually exclusive.
Answers
The given event is not mutually exclusive.
Remember that mutually exclusive events are those events that can't be both true, that is, if one event is true, then the other is false.
The probability of this event would be
[tex]P=\frac{6+5-1}{36}=\frac{10}{36}=\frac{5}{18}\approx0.28[/tex]Therefore, the probability is 0.28, or 28%, approximately.If the radius of circle M is 7, and LK = 18, find JK
Answers
Answer:
JK = 24
Explanation:
If the radius of circle M is 7, we can say that MJ = 7 and ML = 7
So, the length of MK will be equal to:
MK = ML + LK
MK = 7 + 18
MK = 25
Now, we have a right triangle JMK, and we know the length of one leg MJ = 7 and the length of the hypotenuse MK = 25. Using the Pythagorean theorem, we can find the length of the other side JK, so
[tex]\begin{gathered} JK=\sqrt[]{MK^2-MJ^2^{}} \\ JK=\sqrt[]{25^2-7^2} \\ JK=\sqrt[]{625-49} \\ JK=\sqrt[]{576} \\ JK=24 \end{gathered}[/tex]Therefore, the value of JK is 24.

In the quadrilateral below. “Angle WXZ is congruent to Angle YZX." If Ricardo's conjecture is true, which of the following must be true for Quadrilateral WXYZ to be a parallelogram?
Answers
Answer:
∠YXZ ≅ ∠WZX
Explanation:
Given that “Angle WXZ is congruent to Angle YZX."
The angles are shown in the diagram below.
This means that angles WXZ and YZX are alternate angles and thus,
• WX is parallel to ZY.
Consider the diagram below:
Angles YXZ and WZX are congruent by alternate angles, and thus:
• WZ is parallel to XY.
So, we have shown that the opposite sides of the quadrilateral are parallel.
Therefore, in order for quadrilateral WXYZ to be a parallelogram, Angles YXZ and WZX must be congruent.
The first option (∠YXZ ≅ ∠WZX ) is correct.
Write this ratio as a fraction in simplest form without any units. 25 days to 5 weeks
Answers
Given:
There are given the statement:
25 days to 5 weeks.

Since the equation has only the variable y and it is a constant value, that means this equation is represented by a horizontal line (the line contains all values of x and always the value of y is 6).

Answers
The ratio is 2:4:9, so we can consider the total parts we are dividing the total as 2+4+9 = 15.
Then, the first person receives 2/15, the second receives 4/15 and the third receives 9/15.
As the total is 75, we can calculate each part as:
[tex]\begin{gathered} p_1=75*\frac{2}{15}=10 \\ \\ p_2=75*\frac{4}{15}=20 \\ \\ p_3=75*\frac{9}{15}=45 \end{gathered}[/tex]Then, the largest share correspond to the third person and is $45.00.

What does congruence of triangle mean?Triangles are said to be congruent if the three angles and three sides of a triangle are equal to the corresponding angles and sides of another triangle.
To be congruent, two triangles must have the same size and shape. The two triangles under consideration must overlap. If you rotate, flip, and/or move the triangle, its position and appearance will look different. In this case, we need to identify the six parts of one triangle and the corresponding parts of the other triangle.
For the triangles ΔAXD and ΔCXD
AD = DC ( congruent sides)
∠XDA = ∠XDC = 90° ( XD is perpendicular to AC)
XD is the common side.
This proves that triangles ΔAXD and ΔCXD are congruent
So it concludes, that XD = XC

$0.10
EXPLANATION
We have that 150 copies are made for a total cost of $15.00
The unit rate of price per copy is the price of each copy of the printing.
To find the unit rate of price per copy, we have to divide the total price by the total number of copies.

The equation of the parabola in the vertex form with vertex (6,-6) and passing through (8,6) is y = 3(x - 6)² - 6 , the correct option is (b) .
In the question ,
it is given that ,
the parabola passes through the point (8,6) .
the vertex of the parabola = (6,-6) .
We know that the equation of parabola in the vertex form with vertex (h,k) is
(y - k) = C.(x - h)²
we substitute the vertex and the point passing ,
we get ,
6 - (-6) = C.(8 - 6)²
6 + 6 = C(2)²
12 = 4C
C = 12/4
C = 3
So , the equation is (y - (-6)) = 3.(x - 6)²
y + 6 = 3(x - 6)²
y = 3(x - 6)² - 6

The mileage of Car A, Car B, and the average of is (x+3)/(x+4), 2/x and [tex]\frac{x^{2} +5x +8 }{x^{2} +4x}[/tex]
It is given that the distance traveled by the car A = x² + 3x
And the distance traveled by car B = 2x + 8
The mileage is given by mile/gallon.
So, the mileage of Car A = distance traveled by car A/gallons of fuel used.
Then,
Mileage of Car A = [tex]\frac{x^{2} +3x }{x^{2} +4x} =\frac{x(x +3)}{x(x+4)} = \frac{x+3}{x+4}[/tex] miles /gallons
Similarly, the mileage of Car B = distance traveled by car B/gallons of fuel used.
Then,
Mileage of Car B = [tex]\frac{2x+8}{x^{2} +4x} = \frac{2(x+4)}{x(x+4)} =\frac{2}{x}[/tex] miles/gallons
Now, the total mileage of A and B is the average of car A and car B,
Mileage of Car A + Mileage of Car B = [tex]\frac{x^{2} +3x }{x^{2} +4x} + \frac{2x+8}{x^{2} +4x} = \frac{x^{2} +5x +8 }{x^{2} +4x}[/tex]

Let x percent of 3436 be 20.
Recall, percentage is expressed in terms of 100. This means that

34.36x = 20
Dividing both sides of the equation by 34.36, we have

Answers
Given:
Miguel Rodriguez borrowed $500 from his brother Julio to pay for books and tuition.
He agreed to pay Julio in 6 months with simple annual interest at 6.2%
So, the interest = r = 6.2% = 0.062
the time = t = 6 months = 6/12 years = 1/2 year
a.) how much will the interest amount to?
The interest is given by the formula:
[tex]I=P\cdot r\cdot t[/tex]Substitute with the given values:
[tex]I=500\cdot0.062\cdot\frac{1}{2}=15.5[/tex]So, the interest = I = $15.5
