Suppose a fair six sided die has been relabeled so that the 6 is replaced with another 5,i.e., the sides read 1,2,3,4,5,5. If the die is rolled five times, what is the probability that we roll five distinct values
Answer:
P(rolling five distinct values) = 1/3888
Step-by-step explanation:
We are told that I the fair sided dice, 6 is replaced with 5.
Thus,the numbers are now;
1,2,3,4,5,5.
This means a total of 6 possible numbers appearing.
Now, in these 6 numbers there are only 5 distinct numbers since 5 occurs twice.
P(1) = 1/6
P(2) = 1/6
P(3) = 1/6
P(4) = 1/6
P(5) = 2/6
Thus,probability of rolling 5 distinct values = 1/6 × 1/6 × 1/6 × 1/6 × 2/6 = 1/3888
You fllp a fair coln 7 times in a row. Let X be the number of heads that come up. Which of the following cannot be a
possible value of X?
2
0
7
16
Answer:
16
Step-by-step explanation:
Given
A coin
[tex]n = 7[/tex] --- Number of flips
[tex]x \to heads[/tex]
Required
Which can't be the value of x
From the question, we understand that the coin was flipped 7 times.
This means that, the highest occurrence of head is:
[tex]x = 7[/tex]
And the list is:
[tex]x = 0[/tex]
So, the range of x is:
[tex]x = \{0,1,2,....,7\}[/tex]
In the above range, only (16) is out of range.
Hence:
[tex]x \ne 16[/tex] --- Number of heads can't be 16

A well-conducted opinion poll showed that 48% of voters surveyed favored the reelection of Congressman Porkbarrel. The people who conducted the survey reported that the poll had a margin of error of 3.5%. Which of the following best describes this statement
A. Based on the procedure by which this figure was generated, it is likely that the population proportion is between 44.5% and 51.5%.
B. About 3.5% of the people polled are likely to change their minds about who they will vote foir.
C. Between 44.5% and 51.5% of the voters will vote for Congressman Porkbarrel.
D. About 3.5% ofthe people interviewed refused to answer the question.
E. The probability is .48 that Congressman Porkbarrel will be reelected.
Answer:
A. Based on the procedure by which this figure was generated, it is likely that the population proportion is between 44.5% and 51.5%.
Step-by-step explanation:
Confidence interval:
We build a confidence interval from a sample proportion, to get an estimate of where the population proportion should likely be.
48% of voters surveyed favored the reelection of Congressman Porkbarrel, with a margin of error of 3.5%.
48 - 3.5 = 44.5%.
48 + 3.5 = 51.5%.
Following the concept of a confidence interval, the population proportion is likely to be between 44.5% and 51.5%, and thus, the correct answer is given by option A.
what is the solution set for this inequalty? -8x + 40> -16
Answer:
x < 7
Step-by-step explanation:
-8x + 40> -16
Subtract 40 from each side
-8x + 40-40> -16-40
-8x >-56
Divide each side by -8, remembering to flip the inequality
-8x/-8 < -56/-8
x < 7

B. A triangle can be equilateral and equiangular at the same time.
C. A triangle can be isosceles and right at the same time.
D. A triangle can be scalene and obtuse at the same time.
Answer:
A. A triangle can be equilateral and obtuse at the same time

Cindy has a chocolate box whose length is 12 cm, height of 8 cm, and width of 6 cm. Find the volume of the box?
WITH SOLUTION PLEASE
Hello there I hope you are having a great day :) Cindy has a chocolate box whose length is 12 cm, height of 8 cm, and width of 6 cm. Find the volume of the box?
V = L x W x H
Volume = length x Width x Height.
12cm x 6cm x 8cm = V = 576cm^3
so the answer is 576cm^3
Hopefully that helps you :)
Step-by-step explanation:
VOLUME : is the quality of three deamination place enclosed by a closed surface it is the space that substance or shape or keep use or contains it is measured in cubic units
A RACTANGULAR :is a three dimensional figure it has length wind and height
to find the value of the box we need to multiply length buy it wide and by its height v=l x w x hlet us analysis the problem above
GIVEN :length =12 cm
height = 8 cm
width=6 cm
SOLUTION :v=1 x w x h
=(12 CM) x (8 CM) x (6 CM)
=576 cm³FINAL ANSWER(:the value of the box is 576 CM ³

For an angle to be in standard position, its vertex is at the origin and the initial side lies on the
A) positive y-axis. B) positive x-axis. C) negative x-axis. D) negative x-axis.
Answer:
B) positive x-axis.
Step-by-step explanation:
angle to be in standard position, its vertex is at the origin and the initial side lies along the positive x axis
Answer:
Positive x axis
Step-by-step explanation:
The angle lies in standard position means it begins from Q1
The first side must be x axis
Then in Q1 x>0 so it's positive x axis
The equation $x + {y = 2 can be rewritten in a form that reveals the y-intercept of the graph of the equatior
Drag numbers to complete the equation that is equivalent to $x + žy = 2 and show the value of the y-intercept
Answer:
[tex]y = \frac{2}{z} - \frac{x}{z}[/tex]
Step-by-step explanation:
Given
[tex]x + zy = 2[/tex]
Required
Rewrite to show y-intercept
We have: [tex]x + zy = 2[/tex]
Subtract x from both sides
[tex]zy = 2-x[/tex]
Divide both sides by z
[tex]y = \frac{2}{z} - \frac{x}{z}[/tex]
The y intercet is: [tex]\frac{2}{z}[/tex]
what is the value of x?

solve for k. 6 = -3(k - 10)
Answer: k = 8
Step-by-step explanation:
-3k + 30 = 6
-3k = -24
k = 8
Answer:
k = 8
Step-by-step explanation:
6 = -3(k - 10)
Divide each side by -3
6/-3 = -3/-3 *(k - 10)
-2 = k-10
Add 10 to each side
-2+10 = k-10+10
8 = k

Answer:
4. (d) 4.38 in³
5. (b) 19 gallons
6. (a) 6.4 yd³
Step-by-step explanation:
4. The equation can be rearranged to find the compressed volume.
Multiply both sides by the compressed volume:
(compression ratio)×(compressed volume) = (expanded volume)
Divide both sides by the compression ratio:
(compressed volume) = (expanded volume)/(compression ratio)
Fill in the numbers and do the arithmetic.
compressed volume = 46.0 in³/(10.5/1) = 4.38 in³
The compressed volume is about 4.38 in³.

5. The area to be covered is 3170 ft². We want to cover it twice, so the total area we want to cover is 2×3170 ft² = 6340 ft². One gallon of paint covers 350 ft². We want to find the smallest integer number of gallons n such that ...
n×(350 ft²) ≥ 6340 ft²
Dividing by the coefficient of n, we have ...
n ≥ 6340/350 ≈ 18.11
The smallest integer value of n is 19. 19 gallons of paint will be needed.
__
6. The quantity of sand needed (q) is proportional to the area to be covered, so we have ...
q/(400 yd²) = (1.6 yd³)/(100 yd²)
Multiplying both sides of this equation by 400 yd² gives ...
q = (1.6 yd³)(400/100) = 6.4 yd³
6.4 yd³ of sand will be needed.

determine the term 6 generated by the rule TN is equals to n squared minus n and over 2
Given:
Consider the rule of a sequence is:
[tex]T_n=\dfrac{n^2-n}{2}[/tex]
To find:
The 6th term generated by the given rule.
Solution:
We have,
[tex]T_n=\dfrac{n^2-n}{2}[/tex]
Substituting [tex]n=6[/tex] in the above rule, we get
[tex]T_6=\dfrac{6^2-6}{2}[/tex]
[tex]T_6=\dfrac{36-6}{2}[/tex]
[tex]T_6=\dfrac{30}{2}[/tex]
[tex]T_6=15[/tex]
Therefore, the 6th term generated by the given rule is 15.
Anybody know this one? I’m set that it is B but I am not too sure
Answer:
D
Step-by-step explanation:
It is D because there are only 3 sides given. I understand where you were going with B, but there is no angle given, (and you cannot prove one either), so the answer is simply D.
A - There is no angle, triangle does not matter
B - There is no angle, triangle is correct
C - It is similar, they have the same scale factor
D - There are 3 sides, and the triangle is correct

Answer:
∠1 = ∠8
Step-by-step explanation:
Because they are ALTERNATE EXTERIOR ANGLE
Answer:
∠1 = ∠8
Step-by-step explanation:
Because alternate exterior angles are equal.
Also there is no angle given so you cant work them out.
simply put:
∠1 = ∠8
∠1 = ∠4
∠3 = ∠2
∠1 = ∠5
∠2 = ∠6
∠2 = ∠7
∠5 = ∠8
∠4 = ∠8
∠7 = ∠6
∠7 = ∠3

Show that the transformation T defined by
T(x1, x2) = (2x1 - 3x2, X1+4, 5x2) is not linear.
Let u = (1, 0) and v = (0, 1). Then
T (u) = (2*1 - 3*0, 1 + 4, 5*0) = (2, 5, 0)
T (v) = (2*0 - 3*1, 0 + 4, 5*1) = (-3, 4, 5)
=> T (u) + T (v) = (-1, 9, 5)
but
T (u + v) = T (1, 1) = (2*1 - 3*1, 1 + 4, 5*1) = (-1, 5, 5)
=> T (u + v) ≠ T (u) + T (v)
which means T does not preserve addition, so it is not linear.
