1. All of the variables below are directly proportional, write an equation linking them:
a. V= 12 when M =4
b. T= 5 when S=1
c. Y= 34 when x=2
d. H=48 when M=4
e. P= 5 when N=10
Answers
Answer:
a. V = 3M
b. T = 5S
c. Y = 17x
d. H = 12M
e. P = 0.5N
Step-by-step explanation:
a. V= 12 when M =4
12/4 = 3, so in this case, V is 3 times M, that is, V = 3M
b. T= 5 when S=1
5/1 = 5, so in this case, T is 5 times S, that is, T = 5S
c. Y= 34 when x=2
34/2 = 17, so in this case, Y is 17 times x, that is, Y = 17x
d. H=48 when M=4
48/4 = 12, so in this case, H is 12 times M, that is, H = 12M
e. P= 5 when N=10
5/10 = 1/2 = 0.5, so in this case, P is half of N, that is, P = 0.5N

Example: a = a In this case, it could be seen as ST ≅ ST because they have/are the same side(s).RST ≅ UTS1. SAS theorem states that: two triangles are equal if two sides and the angle between those two sides are equal.

A set of cards contains cards numbered 1 – 8. Mrs. Jacob’s class is conducting an experiment in which a card is drawn from the pile, the number is recorded, and then the card is returned to the set. The class will conduct 1,000 trials. Based on the theoretical probability, which is the best prediction for the number of times a 4 will be drawn from the pile?
Answers
Answer: 125
The best prediction for the number of times a 4 will be drawn from the pile is:
A set of cards contains cards numbered 1 – 8.
So, the theoretical probability that 4 comes up is:
Ratio of Number of favorable outcome( outcome of 4) to the total umber outcome(i.e. 8 )
Hence, Theoretical Probability that 4 is drawn=1/8
Now, out of 1000 trials the best prediction of number of times 4 is drawn is:
(The probability of drawing 4)×(Number of experiments or trials)
=(1/8)×1000
=125

Approximately, what percentage of the parts was NOT defective?
Answers
Answer: Percentage of not defective parts =88.88% which can be rounded up to 89%
Step-by-step explanation:
Total part manufactured= 36
defective parts = 4
Non defective parts = 36-4 = 32.
Percentage of not defective parts = Number of not defective parts / Total parts manufactured x 100

c) 3 out of 298 is 1.01 %
d) 1 out of 1000 is 0.1 %
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
33% is approximately 1/3 of a whole ; that is 1/3 of 100%
Hence, 59 / 3 = approximately 19
Approximately 20
Another way is to take 59 as 60, nearest 10, then divide by 3 to obtain ; (60 /3) = 20
To obtain 25% of 98.50
25% = 1/4th
Take value as 98 and divide by 4
Take value as 100 and divide by 4
2% of 150 people
2% = 1/50
Quick division of 150 into 50 places to obtain the approximate value.
To obtain the exact solution for the questions above :
Multiply 33% by 59
0.33 * 59 = 19.47
Multiply 25% by $98.50
0.25 * $98.50
$24.625
Multiply 2% by 150
0.02 * 150
= 3 people

Answers
Answer:
$ 2,200
Step-by-step explanation:
If it cost $1,100 to make 500 then double that and you get $2,200
Answer:
$2100
Step-by-step explanation:
After 500 cards, there is a discount.
(1100/500 = 2.2) So, $2.20 per card for the first 500 cards.
For every 150 cards after the initial 500, it costs $300, or $2.00 per card. (300/150 = 2)
If you want 1,000 cards, you are ordering 500 of them at $2.20 per card and the second 500 cards at $2.00 per card.
(500x2.2) + (500x2)= 2100

the amount people pay for cable service varies quite a bit but the mean monthly fee is $142 and the standard deviation is $29. the distribution is not normal many people pay about $76 for basic cable and about $160 for premium service but some pay much more. a sample survey is designed to ask a simple random sample of 1,500 cable service customers how much they pay. let x hat be the mean amount paid.
Part a: what are the mean an standard deviation of the sample distribution of x hat show your work and justify your reasoning.
Part b: what is the shape of the sampling distribution of x hat justify your answer.
Part C: what is the probability that the average cable service paid by the sample of cable service customers will exceed $143? show your work.
Answers
Answer:
a) By the Central Limit Theorem, the mean is $142 and the standard deviation is $0.7488.
b) By the Central Limit Theorem, approximately normal.
c) 0.0901 = 9.01% probability that the average cable service paid by the sample of cable service customers will exceed $143
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
The mean monthly fee is $142 and the standard deviation is $29.
This means that [tex]\mu = 142, \sigma = 29[/tex]
Part a: what are the mean an standard deviation of the sample distribution of x hat show your work and justify your reasoning.
Sample of 1500(larger than 30).
By the Central Limit Theorem
The mean is $142
The standard deviation is [tex]s = \frac{29}{\sqrt{1500}} = 0.7488[/tex]
Part b: what is the shape of the sampling distribution of x hat justify your answer.
By the Central Limit Theorem, approximately normal.
Part C: what is the probability that the average cable service paid by the sample of cable service customers will exceed $143?
This is 1 subtracted by the pvalue of Z when X = 143. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{143 - 142}{0.7488}[/tex]
[tex]Z = 1.34[/tex]
[tex]Z = 1.34[/tex] has a pvalue of 0.9099
1 - 0.9099 = 0.0901
0.0901 = 9.01% probability that the average cable service paid by the sample of cable service customers will exceed $143

Haley's anole lizard has a tail that is 7.25 centimeters long. Caleb's anole lizard has a tail that is 6.17 centimeters long. An anole lizard's tail is half the length of the lizard. How much longer is Haley's lizard than Caleb's lizard? Show your work.
Answers
Answer: 2.16 centimeters
Step-by-step explanation: You would multiply the tail lengths by two, since the tail length is half of the lizards body.
7.25 x 2 = 14.5 and 6.17 x 2 = 12.34
Then you would subtract Haley's lizard's length from Caleb's lizard's length. 14.5 - 12.34 = 2.16
Good luck! :D
Haley's lizard is 2.16 centimeters longer than Caleb's lizard
What is the fundamental principle of multiplication?
Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We would multiply the tail lengths by two, since the tail length is half of the lizards body.
Thus,
7.25 x 2 = 14.5
6.17 x 2 = 12.34
Then we would subtract Haley's lizard's length from Caleb's lizard's length.
14.5 - 12.34 = 2.16
Therefore, Haley's lizard is 2.16 centimeters longer than Caleb's lizard
