Solving a Proportion Use proportional reasoning to determine the value of a in the proportion shown below. Three-fifths = StartFraction a + 5 Over 25 EndFraction a = 1 a = 25 a = 10 a = 15
Answers
Answer:
\(a = 10\)
Step-by-step explanation:
Given
\(\frac{3}{5} = \frac{a + 5}{25}\)
Required
Find a
\(\frac{3}{5} = \frac{a + 5}{25}\)
Multiply both sides of the equation by 25
\(25 * \frac{3}{5} = \frac{a + 5}{25} * 25\)
\(5 * 3 = a + 5\)
\(15 = a + 5\)
Subtract 5 from both sides
\(15 - 5 = a + 5 - 5\)
\(10 = a\)
\(a = 10\)

For the equation, determine whether the equation is true for all, some, or no values of x.
Explain how you know.
Answers
Answer:
You can check if an equation is true for all some or no values of x by simply to try and solve the equation if you get something like x = x, then the equation is true for all, if you get a specific answer like x=3, then it is true to some values, in simple terms. Try and solve the equation there is no other way to check unless you solve, I don't know if there is another way but this is just my intution.

Is the median or the mean a better center for this data and why? (1 point) Mean; because the data is normally distributed and has an outlier Mean; because the data clusters on the right and is not symmetric Median; because the data is normally distributed and has an outlier Median; because the data clusters on the right and is not symmetric
Answers
Answer:Median; because the data is not symmetric and there are outliers.
Step-by-step explanation:We know that a median is a central tendency of a data and it best represents the given data set.
From the given information we see that the data is skewed to the right since most of the data points takes the higher value and the data is not symmetric as it is skewed.
Hence, last option is the correct answer.

A garden hose sprays 24 gallons of water in 1 minute. The ratio of pints to gallons is 8 to 1.
Question: How many pints of water does the garden hose spray in 1 minute?
Answers
Answer:
192
Step-by-step explanation:
24 * 8 (number of pints in a gallon)
So we know the hose sprays 24 gallons of water a minute. We also know that 8 pints equal a gallon. So to figure out how many pints are in one minute, we multiply 8 x 24, since we have 24 gallons a minute and 8 pints equal a gallon.
This equals 192 pints a minute.
The pacific ocean covers 1/3 of Earth surface the Atlantic Ocean cover 1/5 of Earth surface, what fraction of Earth surface is covered by both oceans?

The part of earth covered by both of the oceans is 8/15
What is a fraction?A fraction represents part of a whole. When something is broken up into a number of parts, the fraction shows how many of those parts you have.
Given that, The Pacific Ocean covers 1/3 of the Earth surface the Atlantic Ocean covers 1/5 of the Earth surface,
To find the total area covered we will add both the area,
1/5+1/3
= 8/15
Hence, The part of earth covered by both of the oceans is 8/15

A little help here? And can anyone explain this?
Answers
Answer:
D.
Step-by-step explanation:
According to the dot plot,
3 students spend 0.5 minutes brushing their teeth.
2 students spend 1.5 minutes brushing their teeth.
1 student spends 2.5 minutes brushing their teeth.
2 students spend 3.5 minutes brushing their teeth.
1 students spend 4 minutes brushing their teeth.
So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}
Median: The middle number in a set that is ordered from least to greatest.
In this example, the median is 1.5
Mean: The sum of all values divided by the number of values.
In this set there are 9 values so we’ll divide the sum by 9
In this example, the mean would be:
(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9
18 ÷ 9 = 2
If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values
