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?
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

Answer:
x= 12/7
Step-by-step explanation:
3x+4x=12
Step 1: Simplify both sides of the equation.
3x+4x=12
(3x+4x)=12(Combine Like Terms)
7x=12
7x=12
Step 2: Divide both sides by 7.
7x 7 = 12 7 x= 12 7
12/7

A manager found that 4 out of 36 parts manufactured in one day were defective.
Approximately, what percentage of the parts was NOT defective?
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
= 32/36 x 100= 88.88%

c) Describe two quick ways to find approximately 2% of 150 people.
2. How would one perform the EXACT calculations in #1? Describe the process IN WORDS1
3. Quick fractions to percentages:
a) 5 out of 25 is 20 %
b) 20 out of 80 is 25 %
c) 3 out of 298 is 1.01 %
d) 1 out of 1000 is 0.1 %
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

The cost of a business to make a greeting cards can be divided into one-time cost (e.g.,a printing machine) and repeated cost (e.g.,ink and paper )suppose the total cost to make 500 cards is 1,100 and the total cost to make 650 cards is 1,400 what is the total cost to make 1,000 cards round your answer to the nearest dollar
ASAP !
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
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
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

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.
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
