Someone help me : The Venn diagram below shows the number
of customers in a restaurant who ordered
starters and desserts. There were 23
customers in total.
What is the probability that a customer
picked at random ordered a starter but did
not order a dessert?
Give your answer as a fraction in its
simplest form.
Answers
Answer:
5/23
Step-by-step explanation:
▪︎ There are 23 customers in total.
▪︎ Only 5 of them ordered a starter but not a dessert.
▪︎ => 5/23
The probability that a customer picked at random ordered a starter but did not order a dessert = 5/23
What is probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Total Customers= 23
and, Customer like starter=5
Customer like Dessert =8
Customer like both =7
So, probability that a customer picked at random ordered a starter but did not order a dessert = 5/23

Which distance measures 7 units? L 50+5 7 -8 -7 -6 5 4 3 -2 -1 0 1 2 O the distance between points L and M O the distance between points L and N O the distance between points M and N the distance between points M and P 3 4 OL 5 6 s 8
Answers
The distance that measures 7 units is the distance between points M and P
How to determine the distance?The complete question is in the attached image
The points are given as:
L= -7
M = -1
N = 2
P = 6
The distance between any points A and B is calculated using:
AB = |B - A|
Using the above formula, we have:
MP = |6 -(-1)|
Evaluate the difference
MP = |7|
Remove absolute bracket
MP = 7 units
Hence, the distance that measures 7 units is the distance between points M and P

A train travels at 100 milers per hour. An equation can be written that compares the time (t) with the distance (d). Define the domain and range
Answers
Answer:
The domain is t ≥ 0
The range is D ≥ 0
Step-by-step explanation:
[tex]rate = \frac{distance}{time}[/tex]
D(t) = 100t + d₀
t is the time measured in hours.
d₀ is the initial position of the train.
We can assume the distance they go is not negative so...
The domain is t ≥ 0
The range is D ≥ 0
Put the following equation of a line into slope-intercept form, simplifying all fractions. 4x+4y=-28
Answers
Answer:
y=-x-7
Step-by-step explanation:
Slope-intercept form is y=mx+b
We have the equation 4x+4y=-28 and must put it into the form above. To do this first subtract 4x from both sides.
4x-4x+4y=-28-4x
This equals 4y=-4x-28. Now, divide 4 from both sides.
4y/4=-4x/4-28/4
y=-x-7

Esta resulta em uma equação de 3° grau incompleta, já que há uma incógnita de potência 3, uma de potência 2, não há uma incógnita de potência 1 mas há as constantes, que as unindo forma a constante 1.

Given the graph of trapezoid FOUR and its reflection. Use the coordinates of the images’ vertices, U and U' to to algebraically find the line of reflection.
x = -1
y = 1
x = 1
y = -1
Answers
Answer:
y = -1
Step-by-step explanation:
Because the coordinate of U and U' is (5, 0) and (5, -2), the line that is right in the middle would be y = -1.
Or you can compare two of the coordinates to create the line of reflection.
For example: R (0,0), R'(0, -2)
U(5, 0), U'(5, -2)
The middle points are (0, -1) (5, -1).
In this case, y = -1.
The graph shows which system of inequalities

The shape consists of a rectangle on the bottom and a trapezoid on the top.
Rectangle
A rectangle has a very simple Area formula. It is Area = L*W. In this case the L = 14 m and is horizontal. The width is at right angles to the length and is marked as 3.
Area = L * w
L = 14
w = 3
Area = 14 * 3 = 42 m^2
Trapezoid
The trapezoid is a bit more complicated and some things have to be found. First of all b1 is the first base of the trapezoid. It is parallel to and equal to the Length of the rectangle. b2 is marked 10 meters. The height is just a bit more complicated. The total height of the figure is 8 m. You can't count the 3 m of the rectangle as part of the height because b1 comes only to the top of the rectangle. The height is 8 - 3 = 5
Area = 1/2(b1 + b2)*h/2
b1 = 14
b2 = 10
h = 8 - 3 = 5
Area = 1/2 ( 14 + 10) * 5 / 2
Area = 1/2 (24)*5
Area = 12 * 5
Area = 60 m^2
Total Area 102 m^2

Round your answer to the nearest thousandth.
Answers
Answer:
x ≈ 12.182
Step-by-step explanation:
1 - 2lnx = - 4 ( subtract 1 from both sides )
- 2lnx = - 5 ( divide both sides by - 2 )
lnx = 2.5
x = [tex]e^{2.5}[/tex] ≈ 12.182 ( to the nearest thousandth )
Answer:
x = 12.182 (nearest thousandth)
Step-by-step explanation:
Given equation:
[tex]1-2 \ln x=-4[/tex]
Subtract 1 from both sides:
[tex]\implies 1-1 -2 \ln x =-4-1[/tex]
[tex]\implies -2 \ln x=-5[/tex]
Divide both sides by -2:

[tex]\textsf{As }\: \ln x=\log_ex \:\:\textsf{}[/tex], the natural logarithm can be canceled by giving both sides a base of e (Euler's number):
