I will provide the approach and work it out. However, I am error prone, so check the arithmetic.
This is a Bayes Theorem problem.
Consider 3 "causes for a 4", Die A, B, or C, and an event, E.
The probability of each cause, given the event 4 is
[tex]P(A|4)=\frac{P(A)P(4|A)}{P(A)P(4|A)+P(B)P(4|B)+P(C)P(4|C)}[/tex]
[tex]P(B|4)=\frac{P(B)P(4|B)}{P(A)P(4|A)+P(B)P(4|B)+P(C)P(4|C)}[/tex]
[tex]P(C|4)=\frac{P(C)P(4|C)}{P(A)P(4|A)+P(B)P(4|B)+P(C)P(4|C)}[/tex]
Since the rolled die is chosen at random,
P(A)=P(B)=P(C)=1/3
Also, from the numbers on the faces of each die,
P(4|A)=1/6
P(4|B)=1
P(4|C)=1/3
Making all the substitutions, we get
P(A|4)=1/9
P(B|4)=6/9
P(C|4)=2/9
That these sum to 1 is promising (maybe I didn't make a mistake).
Next we must roll the die again and the probability of a 4 could be because the die is A, B, or C. Thus, the desired probability is given by
P(A|4)P(4|A)+p(B|4)P(4|B)+P(C|4)P(4|C)
This evaluates to
(1/9)(1/6)+(6/9)(1)+(2/9)(1/3)=41/54

Kiran and Clare like to race each other home from school. They run at the same speed, but Kiran's house is slightly closer to school than Clare's house. On a graph, their distance from their homes in meters is a function of the time from when they begin the race in seconds.
As you read the graphs left to right, would the lines go up or down?
What is different about the lines representing Kiran's run and Clare's run?
What is the same about the lines representing Kiran's run and Clare's run?
Answer:
1. Down.
2. Clare's line would be higher because she begun further away from her house.
3. The lines would have the same slope since they are going the same speed.

sodas and $10.95 for each pizza, how many pizzas did she buy if she spent $89.22?
Which equation models this scenario?
12.57 + 10.95 = 89.22
10.95x + 12.57 =
89.22
12.57x + 10.95 =

A rectangle has a length of (5x+2) and a width of (3x-7). Find the perimeter of the rectangle.
Answer:
Perimeter = 2(5x-2)+2(3x-7)
Step-by-step explanation:
The perimeter (P) of any rectangle can be represented in terms of length (L) and width (W) with the equation P=2L+2W.
You multiply the length and width of the rectangle by two, since it's only giving one expression for the length and width.

Each circle counts as one whole, Write a mixed number giving the amount shaded. Then, write this amount as an improper fraction.
Answer:
[tex]2 \frac{2}{5} [/tex]
[tex] \frac{12}{5} [/tex]
Step-by-step explanation:
As a mixed fraction, There are 3 circles with 5 pieces in each so our denominator will be 5
The number that is shaded is 2 whole circles so that is 10 and 2 out of 5 of last one.
The whole number is 2 and the fraction for the last circle is 2/5 so our mixed number is
[tex]2 \frac{2}{5} [/tex]
Now to find the improper fraction turn 2 into a fraction with 5 as a denominator.
[tex] \frac{2}{1} \times \frac{5}{5} [/tex]
Which equal
[tex] \frac{10}{5} [/tex]
Then add 2/5 to 10/5
[tex] \frac{10}{5} + \frac{2}{5} = \frac{12}{5} [/tex]

Graph: f(x) = 0.5^x- 3
Step 1: Calculate the initial value of the function.
f(0) =
The initial value of a function is the value of the function, when x = 0
The initial value of the function is -2.
The function is given as:
[tex]\mathbf{f(x) = 0.5^x - 3}[/tex]
To calculate the initial value, we simply substitute 0 for x.
So, we have:
[tex]\mathbf{f(0) = 0.5^0 - 3}[/tex]
Evaluate the exponents
[tex]\mathbf{f(0) = 1 - 3}[/tex]
Subtract 3 from 1
[tex]\mathbf{f(0) = - 2}[/tex]
Hence, the initial value of the function is -2.

. Find \text{m}\angle U.m∠U
Answer:
Hi how are you doing today Jasmine
In triangle UVW, If m∠U = m∠W of a triangles then m∠U = 74.5° when m∠W=31°
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
The sum of all angles of a triangles should be equal to 180 degrees
Given that the angles opposite UV and VW are congruent.
So ΔUVW is an isosceles triangle.
Which is nothing but m∠U = m∠W
Since the measures of the angles of a triangle have a sum of 180, then
m∠U + m∠W + m∠V = 180
m∠U + m∠U + 31 = 180
Subtract 31 from both sides
2 m∠U = 180-31
2 m∠U =149
Divide both sides by 2
m∠U =74.5°

Answer:
z = -3/2 , z = -1/2
Step-by-step explanation:
Given:
7z² + 8z + 3 = 3z²
Find:
Values of z
Computation:
7z² + 8z + 3 = 3z²
7z² + 8z + 3 - 3z² = 0
4z²+ 8z + 3 = 0
4z²+ (6+2)z + 3 = 0
4z²+ 6z + 2z + 3 = 0
2z(2z + 3) + 1(2z + 3) = 0
(2z + 3)(2z + 1) = 0
So,

Answer:
4. Given
6. Definition of verticle angles
7. Algebra/part-whole-postulate/sum of interior angles in a triangle/CPTCTC (Corresponding parts of congruent triangles are congruent)
Step-by-step explanation:
number 4 is just...given because it shows that they're both right angles
6, it's literally the definition of verticle angles
7, since we know that angle TQU and angle RSU are congruent and angle QUT and SUR are congruent, if we subtract those from 180, that means those two angles also have to be congruent
Also, the two triangles are congruent by LA or ASA, so CPCTC would also work
Part-whole-postulate, same reasoning as algebra.
Sum of interior angles in a triangle, same as algebra.
