20%
Find the probability that a randomly chosen customer ordered a burger given that they ordered fries.
P (burger fries) =
Answer:
0.80
Explanation:
Since the results are not shown properly, I attach the picture with full question inlcuding the diagram that shows the results correctly.
You need to determine P(burger|fries)
That is the ratio of people that ordered burgers from the set of people that ordered fries (the intersection of the two circles) to the total people who ordered fries (the blue circle, including the intersection of the two circles).
The venn diagram shows that the set of people who ordered fries was 10% + 40% = 50% (the percentage inside the blue circle, including the intersection with the purple circle)
And from that set, the subset of people who also ordered burgers is 40% (the intersection of the two circles).
Thus, the probability that a randomly chosen customer ordered a burger given that they ordered fries is:
[tex]P(burger\mid fries)=\dfrac{P(burger\cap fries)}{P(fries)}[/tex]
[tex]{P (burger\mid fries)=\dfrac{40\% }{50\% }=0.80=80\%[/tex]
The probability that a randomly chosen customer ordered a burger given that he ordered fries is 80%.
To determine the probability that a randomly chosen customer ordered a burger given that he ordered fries, the following calculation must be performed:
Fries = 10% Fries and burgers = 40% Burgers = 30% None = 20% Fries + Fries and burgers = 50% 50 = 100 40 = X 40 x 100/50 = X 80 = X
Therefore, the probability that a randomly chosen customer ordered a burger given that he ordered fries is 80%.

The volume of this solid figure is
Answer:
[tex]v = 183 {cm}^{3} to \: the \: nearest \: whole \: number[/tex]
Step-by-step explanation:
Volume of a cone is given as:
[tex]v = \frac{1}{3} \times\pi \times \ {r}^{2} \times h[/tex]
where,
pi = 3.14
r = radius = half of diameter; 10cm/2 = 5cm
h = height = 3cm + 4cm = 7cm
Thus,
[tex]v = \frac{1}{3} \times 3.14cm \times {5}^{2} cm \times 7cm[/tex]
[tex]v = \frac{1}{3} \times 3.14cm \times 25cm \times 7cm[/tex]
[tex]v = \frac{1}{3} \times 549.50 {cm}^{3} [/tex]
[tex]v = \frac{549.50 {cm}^{3} }{3} [/tex]
[tex]v = 183.17 {cm}^{3} [/tex]
[tex]v = 183 {cm}^{3} to \: nearest \: whole \: number[/tex]

Answer: 0.0776
Step-by-step explanation:
Since the manufacturer knows that 2% of its microchips are produced with a certain defect. Then
P( defective) = 2/100 = 0.02
P( non defective) = 1 - 0.02 = 0.98
Probability of all 4 not defective will be

A bag contains 25 cents and 50 cent coins whose total value is $30 if the number of 25 cent coins is four times that of 50 cent coins, find the number of each type coins. please may I also have the equation.
Number of 25 cents coins is 80 and number of 50 cents coins is 20.
Step-by-step explanation:
Given,
A bag contains of total value $ 30.
Number of 25 cent coins is four times that of 50 cent coins.
To find number of 25 cents coin is x
Number of 50 cents coin is y
According to the problem,
[tex]\frac{x}{4} +\frac{y}{2} = 30[/tex] ----- eq 1
x = 4y------ eq 2
Now, we will solve these two equation.
Putting the values of x = 4y in eq 1 we get,
[tex]\frac{4y}{4} +\frac{y}{2} = 30[/tex]
or, [tex]y +\frac{y}{2} = 30[/tex]
or, [tex]\frac{3y}{2}[/tex] = 30
or, y = 20
So, x = 4×20 = 80
Hence,
Number of 25 cents coins = 80 and number of 50 cents coins = 20
Answer:
Step-by-step explanation:
Let 25 cent coin be A and 50 cent coin be B
Given
Total value of 25 cents coin and 50cents coin is $30
That’s
25A + 50B = 30
Also, 25 cents coin is equal to four times that of 50
So,
A = 4B
We now have
25A + 50B = 30
A = 4B
Substitute 4B for A into the first equation
25(4B) + 50B = 30
25 x 4B + 50B = 30
100B + 50B = 30
150B = 30
Divide both sides by 150 to isolate B
150B/150 = 30/150
B = 1/5
Recall
A = 4B
Therefore
A = 4 x 1/5
= 4/5
Number of 25 cents coin is 4/5 and that of 50 cents coin is 1/5
J is the midpoint of CT CJ = 8x-5 and JT = 5x+4 find CT
The value of CT is 13x - 1.
What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment CT, where the length of line segment CT refers to the distance between its endpoints, C and T.
Given that J is the midpoint of CT
CJ = 8x-5 and JT = 5x+4
C______________J______________T
⇒ CT = CJ + JT
Since J is the midpoint of CT, So CJ = JT
⇒ CT = CJ + JT
Substitute the values of CJ = 8x-5 and JT = 5x+4 in the above equation,
⇒ CT= (8x-5)+(5x+4)
⇒ CT= 8x-5+5x+4
Rearrange the likewise terms, and apply the arithmetics operation,
⇒ CT = 8x + 5x - 5 + 4
⇒ CT = 13x - 1
Hence, the value of CT is 13x - 1.

#SPJ2
Final answer:
To find the length of CT, solve the equation 8x-5 = 5x+4 to find x, then substitute the value of x into either CJ or JT to find the segment's length and double it.
Explanation:
The student is asking a geometry problem where they need to find the length of the segment CT given that J is the midpoint of CT with CJ being 8x-5 and JT being 5x+4. Since J is the midpoint, these two segments are equal in length, thus the equation to solve is 8x-5 = 5x+4.
To find the value of x, follow these steps:
Subtract 5x from both sides: 3x-5 = 4.Add 5 to both sides: 3x = 9.Divide both sides by 3: x = 3.Once x is found, substitute it back into either CJ or JT expression to find the length of one segment. Then, double that length to find CT, as CT is equal to 2 times CJ or 2 times JT.

Volume and Surface Area! 30 POINTS
Answer:
Volume: 5200 cubic centimeters
Surface area: 1520 square centimeters
Step-by-step explanation:
Volume = [1/2 x 5 x side x apothem] x height
(The apothem is that little 8 cm mark, the height is 26, the side is 10.)
Plug those values in:
V = 1/2 * 5 * s * a * h
= 1/2 * 5 * 10 * 8 * 26 = 5200 cubic centimeters
Surface area = 2(base area) + 5(lateral area)
Perimeter of base = 10*5 = 50 cmBase area = pa/2 = 50*8 / 2 = 200 square centimetersLateral area = lw = 26*10 = 260 square centimetersSA = 2(200) + 5(260) = 1520 square centimeters
