Step-by-step explanation:
1/7×2/3=2/21
Solution with Steps
1/7×2/3=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
1×2 and 7×3=2/21
This fraction cannot be reduced.
Therefore:
1/7×2/3=2/21
Solution by Formulas
Apply the fractions formula for multiplication, to
1/7×2/3
and solve
1×2 and 7×3
=2/21
Answer:
1/7 × 2/3 is 2/21
becuase, if you times the numerators, which are the top numbers; and then the denominators which are the bottom numbers; like if you multiply 1×2 you get 2 and 7×3 is 21.

Answer:
250 feet by 250 feet
Step-by-step explanation:
The largest area that can be closed is a square, so divide 1000 by 2 to determine the length and width of the yard. Length is 250 feet, and width is 250 feet.

The following are the last 10 run scores Colin got in cricket: 18 , 25 , 28 , 15 , 6 , 18 , 2 , 4 , 25 , 15 a) Work out Colin's mean score. b) Colin plays cricket again on Sunday. He gets 31 runs. What is his new mean score? Give your answers as decimals.
~Shoto Todoroki here~
Colin's mean score of his 10 runs is 18.8.
Colin's new mean score after the game on Sunday is 20.
Mean is a measure of central tendency. It is used to describe a data set. It is the sum of a set of observations divided by the number of observations. It is also known as average.
Mean = sum of scores / total number of scores.
Colin's mean scores can be determined by dividing the sum of scores by total number of scores.
Sum of scores = (20 + 29 + 34 + 19 + 8 + 12 + 0 + 23 + 29 + 14) = 188
Number of scores = 10
Mean of scores = 188 / 10 = 18.8
Colin's new mean score can be determined by adding 32 to the sum of scores already determined and dividing the sum by the total number of scores.
New sum of scores = 188 + 32 = 220
Number of scores = 11
Mean scores = 220 / 11 = 20

Arvilla laid out the stones for a necklace in a big circle, with each stone spaced an equal distance from its neighbors. She then counted the stones in order around the circle. Unfortunately, before she finished counting she lost track of where she had started, but she realized that she could figure out how many stones were in the circle after she noticed that the sixth stone was directly opposite the seventeenth stone. How many stones are in the necklace?
Using proportions, it is found that there are 22 stones in the circle.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, the sixth stone was directly opposite the seventeenth stone, hence over half the circle, there was 11 stones.
Then, we apply the proportion, and get that:
0.5n = 11
n = 22.
There are 22 stones in the circle.

Measuring the speed of sound in the ocean is an important part of marine research. One application is the study of climate change. The speed of sound depends on the temperature, salinity, and depth below the surface. For a fixed temperature of 25 degrees Celsius and salinity of 35 parts per thousand, the speed of sound is a function of the depth. At the surface, the speed of sound is 1534 meters per second. For each increase in depth by 1 kilometer, the speed of sound increases by 17 meters per second. Use D for depth (in kilometers) and S for the speed of sound (in meters per second), and find a linear formula for S as a function of D.
Answer:
A linear formula for S as a function of D is S=17D+1534
Step-by-step explanation:
We are supposed to find a linear formula for S as a function of D.
Equation of line : y = mx+c
We are given that At the surface, the speed of sound is 1534 meters per second.
c = 1534
We are given that for each increase in depth by 1 km, the speed increases by 17 m/s
So, Slope = m = 17
Substitute the values in equation
y=17x+1534
x denotes depth
y denotes speed
We are given that Use D for depth and S for the speed of sound
So, S=17D+1534
Hence a linear formula for S as a function of D is S=17D+1534

Jorge travels by taxi from his hotel to the airport. The taxi driver charges an initial fee of $3.50 plus $2.75 per kilometer. Which equation can
be used to find y, the total cost of the trip if x represents the number of kilometers of the trip ?
Answer:
C. [tex] y = 3.50 + 2.75x [/tex]
Step-by-step explanation:
Initial fee charged by the taxi driver = $3.50
Fee charged per kilometer = $2.75
Number of kilometers of travel = x
Total cost charged for a trip = y = initial fee charged for renting a taxi + fee paid based on the number of kilometers travelled
Total cost of the trip can be expressed by the following equation:
[tex] y = 3.50 + 2.75x [/tex]
The answer is C. [tex] y = 3.50 + 2.75x [/tex].

On September 11, 2002, a particular state lottery's daily number came up 9-1-1. Assume that no more than one digit is used to represent the first nine months. a) What is the probability that the winning three numbers match the date on any given day? b) What is the probability that a whole year passes without this happening? c) What is the probability that the date and winning lottery number match at least once during any year? d) If 27 states have a three-digit lottery, what is the probability that at least one of them will come up 1-1-4 on January 14?
The probability that the winning three numbers match the date on any given day is the likelihood of the winning number
The probability that the winning three numbers match the date on any given day is 0.001The probability that a whole year passes without this happening is 0.7407The probability that the date and winning lottery number match at least once during any year is 0.2593The probability that at least one of them will come up 1-1-4 on January 14 is 0.0267The probability that the winning three numbers match the date on any given dayStart by calculating the number of possible outcomes
Each of the three digits can take any of 0 - 9 i.e. 10 digits.
So, the number of possible outcomes is:
[tex]n =10^3[/tex]
[tex]n =1000[/tex]
There can be only one winning date.
So, the probability (p) is:
[tex]p = \frac 1n[/tex]
This gives
[tex]p = \frac 1{1000}[/tex]
[tex]p = 0.001[/tex]
Hence, the probability that the winning three numbers match the date on any given day is 0.001
The probability that a whole year passes without this happeningIn a calendar year, there are 65 days, where the whole year passes without matching the winning numbers.
The dates are:
October 10- October 31 (22 days)November 10 - November 30 (21 days)December 10 - December 31 (22 days)This means that the matching numbers can occur on the remaining 300 days.
The probability that the winning date does not occur on a date is calculated using the following complement rule
[tex]p' = 1 - p[/tex]
So, we have:
[tex]p' = 1 - 0.001[/tex]
[tex]p' = 0.999[/tex]
For the 300 days, we have:
[tex]p = 0.999^{300}[/tex]
[tex]p = 0.7407[/tex]
Hence, the probability that a whole year passes without this happening is 0.7407
The probability that the date and winning lottery number match at least once during any yearThis is calculated using the following complement rule
[tex]p' = 1 - p[/tex]
So, we have:
[tex]p' = 1 - 0.7407[/tex]
[tex]p' = 0.2593[/tex]
Hence, the probability that the date and winning lottery number match at least once during any year is 0.2593
The probability that at least one of them will come up 1-1-4 on January 14In (b), we have:
[tex]p' = 0.999[/tex]
So, the probability is calculated as:
[tex]p =1 - (p')^n[/tex]
Where n is the number of states i.e. n = 27.
So, we have:
[tex]p = 1 - 0.999^{27}[/tex]
[tex]p = 0.0267[/tex]
Hence, the probability that at least one of them will come up 1-1-4 on January 14 is 0.0267
