What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
400 compliments for every 850 reviews
Writing the above statement in form of fraction as
= 400/ 850
= 40/ 85
= 8/ 17
Hence, the rate is 8 compliments / 17 reviews

Use the mean (to the nearest whole number) and standard deviation (to decimals) to evaluate the golfer's performance over the two-year period. Mean Standard deviation Mean Standard deviation b. What is the primary difference in performance between and
Answer:
Step-by-step explanation:
The mean for 2018 scores is:
[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]
[tex]M ean ( \overline X) = \dfrac{74 + 78+79+77+75+73+75+77}{8}[/tex]
[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]
[tex]\mathbf{M ean ( \overline X) = 76}[/tex]
The standard deviation for 2018 scores is:
[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]
[tex]s = \sqrt{\dfrac{ ( 74 -76)^2+( 78 -76)^2+( 79 -76)^2+...+( 73 -76)^2+( 75 -76)^2+( 77 -76)^2}{8- 1} }[/tex]
[tex]s = \sqrt{\dfrac{30}{7} }[/tex]
s = 2.07
The mean and standard deviation for the year 2018 scores is:
2018
Mean 76
Standard deviation 2.07
The mean for 2019 scores is:
[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]
[tex]M ean ( \overline X) = \dfrac{71 + 70+75+77+85+80+71+79}{8}[/tex]
[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]
[tex]\mathbf{M ean ( \overline X) = 76}[/tex]
The standard deviation for 2019 scores is:
[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]
[tex]s = \sqrt{\dfrac{ ( 71 -76)^2+( 70 -76)^2+( 75-76)^2+...+( 80 -76)^2+( 71 -76)^2+( 79 -76)^2}{8- 1} }[/tex]
[tex]s = \sqrt{\dfrac{194}{7} }[/tex]
s = 5.26
The mean and standard deviation for the year 2019 scores is:
2019
Mean 76
Standard deviation 5.26
Difference: Both the two years have the same mean but the 2019 scores have higher variation as compared to 2018 scores.
Thus, the variation in scores was higher in 2019.
⅚of the number of pupils in a class is 4 greater than three-quarters of the number in the class .find the number of pupils in the class
Answer:
48 pupils
Step-by-step explanation:
let the number of people in the class be x
⅚ of the number of pupils in a class is expressed as ⅚x
4 greater than three-quarters of the number in the class is expressed as 3/4x+4
Equating both expressions
⅚x = 3/4x + 4
5x/6 - 3x/4 = 4
(10x-9x)/12 = 4
x/12 = 4
x = 4*12
x = 48
Hence the number of pupils in the class is 48 pupils

a train travels 16 miles in 20 minutes how many minutes would 12 miles be
Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
16 miles = 12 miles
20 mins. how many mins?
16 = 12 cross multiply 16? = 240 divide by 16 240 divided by 16 = 15 miles
20 ? because 15 x 16 = 240
Answer:
It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
Write and solve an equation of ratios:
16 miles 20 min
----------- = -----------
12 miles x
Then 16x = 240, and x = 240/16 = 15.
12. Given a right triangle with the length
of one leg equal to 9 centimeters and
the length of the hypotenuse equal to
15 centimeters, what is the length of
the other leg?
F 6 cm
H square root of 306 cm
G 12 cm
J 144 cm
Answer:
G. 12 cm
Step-by-step explanation:
Length of one leg of right triangle = a = 9 cm
Length of hypotenuse = c = 15 cm
Length of the other leg = b = ?
Applying pythagorean theorem, c² = a² + b², we have:
15² = 9² + b²
15² - 9² = b²
144 = b²
b = √144
b = 12

) A computer program found that the line LaTeX: c=2t-89c = 2 t − 89 is a good fit for the data. Use this equation to predict how many cups of lemonade Lin might sell on a day when the high temperature is 74 degrees. We predict she will sell 40 cups of lemonade.
Answer:
Number of cups of lemonade = 59 cups
Step-by-step explanation:
Given the linear function :
C = 2t - 89
At temperature of 74° ;
The cups of lemonade as calculated using the linear model:
C = 2t - 89 ; where c = cost of lemonade ; t = temperature.
C = 2(74) - 89
C = 148 - 89
C = 59
A function assigns the values. The prediction that she will sell 40 cups of lemonade that day is wrong.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
As it is given that function, c=2t-89, where the number of cups of lemonade is represented by c, and t represents the temperature of the day.
Now, as it is given that the temperature at the day is 74, therefore, the number of cups that will be sold that day can be predicted as,
[tex]c = 2t-89\\\\c = 2(74)-89\\\\c = 148-89\\\\c = 59[/tex]
Hence, the prediction that she will sell 40 cups of lemonade that day is wrong.

A 6-POUND BAG OF CANDY COSTS $11.28 WHAT IS THE COST PER POUND? 10
Answer:
$1.88
Step-by-step explanation:
11.28 / 6 = 1.88
Answer: $1.88
Step-by-step explanation:
We have 6 pounds of candy that cost 11.28, and we need to find the unit rate.
If we want to find the unit rate, or the cost per pound, we can use the equation 11.28 ÷ 6.
We can then divide each side by 6, or solve the equation.
11.28 ÷ 6 = 1.88.
Therefore, the each pound of candy costs $1.88.

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

On a bicycle, Eddie can travel 20 miles in 4 hours. How many hours does it take Eddie to travel 1 mile?
Answer:
1 mile = 0.2 hours
Step-by-step explanation:
Given that,
Eddie can travel 20 miles in 4 hours.
We need to find how many hours does it take Eddie to travel 1 mile.
20 mile = 4 hours
1 mile = (4/20) hours
= 0.2 hours
So, to travel 1 mile will take 0.2 hours.
your family went out to dinner to celebrate your grandmas 100th birthday. The total for the dinner was $208.60, so your parents left a $31.29 tip. What percent of the bill was the tip?
Answer:
[tex]\%Tip = 13.04\%[/tex]
Step-by-step explanation:
Given
[tex]Tip= \$31.29[/tex]
[tex]Bill = \$208.60[/tex]
Required
Determine the percentage of the tip
First, we calculate the amount paid
[tex]Amount = Tip + Bill[/tex]
[tex]Amount = \$31.29 + \$208.60[/tex]
[tex]Amount = \$239.89[/tex]
The percentage of the tip is then calculated using:
[tex]\%Tip = \frac{Tip}{Amount} * 100\%[/tex]
[tex]\%Tip = \frac{31.29}{239.89} * 100\%[/tex]
[tex]\%Tip = \frac{31.29* 100}{239.89} \%[/tex]
[tex]\%Tip = \frac{3129}{239.89} \%[/tex]
[tex]\%Tip = 13.04\%[/tex]
