Answer:
(a) No
(b) No
(c) No
Step-by-step explanation:
Given
See attachment
Required
Select Yes or No for each
To do this, we make use of Euler's formula
[tex]F + V - E = 2[/tex]
Where
[tex]F \to Faces; V \to Vertices; E \to Edges[/tex]
[tex](a):\ Faces = 8; Vertices = 12; Edges = 6[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]8 + 12 - 6 = 2[/tex]
[tex]14 = 2[/tex]
The above equality is false. Hence, (a) does not exist
[tex](b):\ Faces = 6; Vertices = 6; Edges = 4[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]6 + 6 - 4 = 2[/tex]
[tex]8 = 2[/tex]
The above equality is false. Hence, (b) does not exist
[tex](c):\ Faces = 20; Vertices = 30; Edges = 12[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]20 + 30 - 12 = 2[/tex]
[tex]38 = 2[/tex]
The above equality is false. Hence, (c) does not exist

Many games involve chance and they usually involved either dice or cards. For this activity, we will look
at a common game called 7‐11 where two dice are rolled. If the roll adds up to 7 or 11, the player wins.
If the roll adds up to 2, 3, or 12, the player loses. If there is any other sum, it is a draw (no winner or
loser). Use this two‐dice roll scenario to complete the problems below.
. What is the probability for each of the sums below? NOT A MULTIPLE CHOICE.
2=
3=
7=
11=
12=
Answer:
See below.
Step-by-step explanation:
See the attached chart that shows all outcomes for two dice.
There are 36 possible outcomes, all equally likely (if the dice are fair!).
The probability of getting a sum of 2 is 1/36 (only one way to get 2: both dice show 1).
The probability of getting a sum of 3 is 2/36 = 1/18.
The probability of getting a sum of 7 is 6/36 = 1/6 (the most likely sum!)
(Notice how all the sum = 7 outcomes like on a diagonal in the chart?)
The probability of getting a sum of 11 is 2/36 = 1/18.
The probability of getting a sum of 12 is 1/36.

Mr Sharma packed 42 kg of tea into one big bag and 6 small ones each of the same size the big bag contained 3/7 of the tea how many kg of tea did each small bag contain
Answer:
4kg
Step-by-step explanation:
Mr Sharma packed 42 kg of tea into one big bag and sox small bags each of the same size
The first step is to calculate the quantity in the big bag
= 3/7 × 42
= 3×6
= 18
The amount left in the remaining bags is
= 42-18
= 24
Therefore the kg of tea in the small bags can be calculated as follows
= 24/6
= 4
Hence there are 4kg of tea in the small bags

2 Which table represents a function? X y X у 2 -3 -3 0 3 0 -2 1 4 -3 -3 2 2 1 2 3 (1) (3) х X у 1 2 AWNIK -4 1 2 1 NO 4. 1 5 4 6 (2) (4)
The only table that represents a function is the fourth option.
What is a function?
A function is a relation that maps elements from a set (domain) into elements of another set (range).
Such that each element from the domain can be mapped into only one element from the range.
In the table, the "x" values are from the domain, and the "y" values are from the range.
So, if you see a table with the same value of x being mapped into two different values of y, then that relation is not a function.
With that in mind, the only table that meets this property is table number 4.

8 goes in the gray blank space
========================================================
Explanation:
H = heads
T = tails
HHH means we get 3 heads in a row, HHT means heads twice then tails the third time, and so on.
Here are the 8 ways to flip three coins (note: 2^3 = 2*2*2 = 8).
HHHHHTHTHHTTTHHTHTTTHTTTWe see that HHH only comes up once out of 8 total times. Therefore, the probability of getting HHH is 1/8
------------
Another way to see the answer is note that P(H) = 1/2 is the probability of getting heads on a single coin flip
Then with two coin flips, we have P(HH) = P(H)*P(H) = (1/2)*(1/2) = 1/4. Each coin flip is independent of one another.
And finally, P(HHH) = P(H)*P(H)*P(H) = (1/2)*(1/2)*(1/2) = 1/8

The value of an investment after t years is given by the function, A (t) = 500 (1 + 0.07t).
Complete the following statement. The initial value of the investment is_____,and the annual simple interest rate is____percent.
For the first blank
A. $500
B. $700
For the second blank
A.50
B.70
C.7
D.0.5
E.0.07
Answer:
A. $500
C. 7 percent
Step-by-step explanation:
Your problem follows the format of the Simple Interest Formula.
The formula is described as follows: A = P(1 + r*t)
Where P = initial value
r = interest rate as a decimal
t = amount of time.
In your equation of A = 500 ( 1 + 0.07 t )
we can see that 500 represents the P value which is the initial value of the investment.
We can also see that the rate is 0.07. Then converted from a decimal to a percent would be 7 percent.

the sum of two rational numbers is -5 if one of the number is -13/6 find the other number
Answer:
[tex]Let \ the \ number \ be = x\\sum \ of \ 2 \ rational \ numbers = -5\\\\x + \frac{-13}{6} = -5\\\\x - \frac{13}{6} = -5\\\\[/tex]
[tex]x = -5 + \frac{13}{6} = \frac{-30 + 13}{6} = -\frac{17}{6}[/tex]
The other rational number = -17/6
======================================================
Work Shown:
A = first rational number = -13/6B = second rational number = unknownA+B = -5 ... since the sum of both is -5
B = -5-A
B = -5-(-13/6)
B = -5+13/6
B = -30/6 + 13/6
B = (-30+13)/6
B = -17/6 is the answer
---------------
Extra info:
This improper fraction converts to the mixed number -2 & 5/6
In decimal form, it's approximately equal to -17/6 = -2.833
When you have two shapes to compare on a coordinate plane, you can determine the scale factor, knowing that the transformation was a dilation. Generate instructions you would give another student to determine the scale factor. If you know the center of dilation is the origin, you can simply divide any non-zero coordinate of the transformed figure by the corresponding coordinate of the original figure to get the scale factor. Sample Response: Locate two corresponding ordered pairs of the two shapes. Calculate how much the pre-image values were multiplied by to obtain the image values. This is your scale factor. You can calculate this by dividing the coordinates of the mage by the corresponding coordinates of the pre-image. Which did you include in your response? Check all that apply. Use corresponding ordered pairs. Divide the coordinates of the image by the pre-image. Determine that the pre-image times the scale factor produces the image.

During one month, the mean high temperature in Boise, Idaho, was 52.1°F with a standard deviation of 6.5° F. During the same month, the mean high temperature in Death Valley, California, was 81.9° F with a standard deviation of 6.4° F. Select all the statements that are true.
Answer:
B. The average high temperature in Death Valley was greater than the average in Boise
C. The variation of high temperature in Death valley was about the same as the variation in Boise
Step-by-step explanation:
Step 1: In a normal distribution, about 95% of the values are ±2 standard deviations from the mean. ±2 standard deviation from the mean high temperature of Boise is 39.1 to 65.1. Therefore, option A is wrong
Step 2: The average temperature high temperature of each of the places isngiven by their mean high temperatures.
The mean high temperature in Boise, Idaho, was 52.1°F while the mean high temperature in Death Valley, California, was 81.9°F.
Difference between the mean high temperatures is (81.9 - 52.1) = 29.8°F
Therefore, the average high temperature in Death Valley was greater than the average in Boise. Option B is correct.
Step 3: Standard deviation measures how spread out data is. It is a measure of variation of data.
The standard deviation of the high temperature in Boise, Idaho was 6.5° F, while the standard deviation of the high temperature in Death Valley, California was 6.4° F. This two values are about the same. Therefore, option C is correct.
Step 4: In a normal distribution, about 68% of the values are ±1 standard deviations from the mean. ±1 standard deviation from the mean high temperature of Death Valley is 75.5 to 88.3. Therefore, option D is wrong
Step 5: In a normal distribution, about 99.7% of the values are ±3 standard deviations from the mean. ±3 standard deviation from the mean high temperature of Boise is 32.6 to 71.6. Therefore, option E is wrong
