Question 6
In a box of 11 parts, 4 of the parts are defective. Two parts are selected at random without replacement.
Find the probability that both parts are defective.
The probability that both parts are defective is 6/55
Step-by-step explanation:
Defective parts = 4
Total parts = 11
Probability of getting a defective part = 4/11
Probability of getting defective part 2nd time = 3/10
Total probability of getting defective part both the times = (4/11) (3/10)
= (12/110)
= (6/55)
The probability that both parts are defective is 6/55

What is the image of (5,-8)(5,−8) after a reflection over the x-axis?
Answer:
(5,8)
Step-by-step explanation:
(x,y) --> (x,-y)
The image of the point (5, -8) after a reflection over the x-axis is (5, 8).
When reflecting a point over the x-axis, the x-coordinate remains the same while the y-coordinate changes sign. Given the point (5, -8), after a reflection over the x-axis, the new coordinates will be (5, 8).
Here's the step-by-step process:
Keep the x-coordinate the same (x remains 5).
Change the sign of the y-coordinate (-y becomes 8).
Combine the new coordinates to get the reflected point (5, 8).
Therefore, the image of the point (5, -8) after a reflection over the x-axis is (5, 8).

R is inversely proportional to A.
R = 12 when A = 1.5
a) Work out the value of Rwhen A= 5.
b) Work out the value of A when R = 9
Here are the answer: a) R = 3.6 and b) A = 2
Step-by-step explanation:
Given,
R is inversely proportional to A.
R ∝ [tex]\frac{1}{A}[/tex]
so, R = [tex]\frac{k}{A}[/tex] -------eq 1 where k is any constant
To find the values of a) R when A = 5 and
b) Value of A when R = 9
Now,
Putting R = 12 and A = 1.5 in eq 1 we get,
12 = [tex]\frac{k}{1.5}[/tex]
or, k = 12×1.5 = 18
From eq 1 we get,
R = [tex]\frac{18}{A}[/tex] --------- eq 2
Now,
a) Putting A= 5 in eq 2 we get,
R = [tex]\frac{18}{5}[/tex] = 3.6
b) Putting R = 9 in eq 2 we get
R = [tex]\frac{18}{A}[/tex]
or, A = [tex]\frac{18}{9}[/tex] = 2
Answer:
a.3.6
b. 2
Step-by-step explanation:
R is inversely proportional to A
Which means R=k/A
Cross multiply
k=RA
Since R=12
A=1.5
So k=12×1.5
=18
a. We are to determine the value for R
So R=k/A
=18/5
=3.6
b.we are to determine the value for A
So R=k/A
A=k/R
=18/9
=2

Find the mode for the image below
Answer:
7
Step-by-step explanation:
Mode is the number that repeats the most
7 is repeating the most
The mode for the given bar image shown is: 7
How to find the mode of the dataset?In statistics, the mode is a measure of central tendency that refers to the value that appears most frequently in a dataset. It can be used to summarize categorical variables, while the mean and median can only be calculated for numeric variables. The mode is calculated by putting the numbers in order from least to greatest and counting how many times each number occurs.
From the given bar graph, we see that the number that occurs the highest number of times is 7 as it is the tallest bar.

A rectangle has an area of 80cm squared and a perimeter of 48cm find the length and width of the rectangle
2 possible solutions.
When width is 4 cm, length is 20 cm; When width is 20 cm, length is 4 cm
Step-by-step explanation:
Step 1: Let the width of the rectangle be x. Perimeter of the rectangle = 48 cm. Find expression for length.Perimeter of the rectangle = 2(length + width)
48 = 2(length + x)
24 = length + x
⇒ Length = 24 - x
Step 2: Find the dimensions if area = 80 cmArea of the rectangle = length × width
80 = x (24 - x)
80 = 24x - x²
x² - 24x + 80 = 0
x² - 20x - 4x + 80 = 0
x(x - 20) - 4(x - 20) = 0
(x - 4)(x - 20) = 0
⇒ x = 4, 20
24 - x = 20, 4
So there are two possible answers.
When width is 4 cm, length is 20 cm
When width is 20 cm, length is 4 cm

A scuba instructor charges a $150 equipment fee, plus $65 per hour for classes. Write an expression to represent the total cost, C, of lessons as a function of the numefer of hours, h, of the lesson.
Answer: (consider leaving a thanks)
Since the equation representing the total cost is C, we would write:
C = (rest of equation will go here)
Then, since the price goes up with the number of hours (h) by 65$ each hour, we would write it as (65h)
C = 65h (Final part!)
Finally, since 150$ is added on, and isn't connected to the number of hours we would write the equation like this:
C = 65h + 150
These box plots show daily low temperatures for a sample of days in two
different towns. Which statement is the most appropriate comparison of the spreads?
Given:
The box plots show daily low temperatures for a sample of days in two different towns.
We need to determine the most appropriate comparison of the spreads.
Interquartile range of town A:
The interquartile range can be determined by subtracting the end values of the boxes.
Thus, we have;
Interquartile range = 40 - 20
Interquartile range = 20
Thus, the interquartile range for town A is 20.
Interquartile range for town B:
The interquartile range for town B is given by
Interquartile range = 45 - 35
Interquartile range = 10
Thus, the interquartile range for town B is 10.
Hence, the interquartile range (IQR) for town A, 20° is greater than the IQR for town B, 10°
Hence, Option A is the correct answer.

Answer:1197m³
Step-by-step explanation:
Answer:
Volume of a triangular irregular prism=1300.16m^3 = 1300m^2
Volume of a rectangular prism two answers = 1197m^3 or 1233m^3
Step-by-step explanation:
With rectangular prism two answers we need the rectangle surface area first
A = 9 m x 19 m = 171m
or A = 7 m x 19m
The rectangle prism could be 1197m^3 or 1233m^3
depending how big the rectangle is as we calculate that first then multiply by depth. If we had the direction of measurement of the base we would just get one answer and not two.
Rectangular prism A = 171sq
V = 1197m^3 = (171sq x 7)
or V= 1233m^3 = 137sq x 9
If the prism is a irregular prism we add the surface area's
V = (a+b+c)B/3
V = (7x19)(9x7) (9x19) x B = 133 + 63 + 197 x 197 = 3900.5/3 =1300.16
Write the first 5 terms of the
sequence an = 3n – 4
Answer:
- 1, 2, 5, 8, 11
Step-by-step explanation:
Substitute n = 1, 2, 3, 4, 5 into the n th term formula
a₁ = 3(1) - 4 = 3 - 4 = - 1
a₂ = 3(2) - 4 = 6 - 4 = 2
a₃ = 3(3) - 4 = 9 - 4 = 5
a₄ = 3(4) - 4 = 12 - 4 = 8
a₅ = 3(5) - 4 = 15 - 4 = 11
The first 5 terms are - 1, 2, 5, 8, 11
Final answer:
The first 5 terms of the sequence an = 3n - 4 are -1, 2, 5, 8, and 11. Each term is found by substituting the nth term number into the expression and calculating its value.
Explanation:
The student has asked to write the first 5 terms of the sequence an = 3n - 4. To find the terms of this sequence, we simply substitute the values of n (starting from 1 and going up by 1 each time) into the expression and calculate the results.
For n = 1: a1 = 3(1) - 4 = 3 - 4 = -1For n = 2: a2 = 3(2) - 4 = 6 - 4 = 2For n = 3: a3 = 3(3) - 4 = 9 - 4 = 5For n = 4: a4 = 3(4) - 4 = 12 - 4 = 8For n = 5: a5 = 3(5) - 4 = 15 - 4 = 11Therefore, the first 5 terms of the sequence are -1, 2, 5, 8, 11.

4 _[blank]_
Answer:
81,000
Step-by-step explanation:
1 1,000x3= 3,000
2 3,000x3= 9,000
3 9,000x3= 27,000
4 27,000x3= 81,000
The number of bacteria on your phone after 4 hours is 81,000.
Explanation:To calculate the number of bacteria on your phone after 4 hours using the exponential function f(x) = 1,000 * 3^x, we can substitute x with 4. So the equation becomes f(4) = 1,000 * 3^4.
Calculating this, we get f(4) = 1,000 * 81 = 81,000.
