A local weather forecaster uses percentages to describe chances of precipitation. Do you think percentages should be used to express probabilities or fractions? Which do you prefer? Why?
Answer:
It depends on what you prefer
Step-by-step explanation:
personally, i prefer percentages because sometimes fractions can get confusing. imagine someone saying " we have 1/2 chance of rain today and 1/8 of it will be scatterd showers while for 1/16th of the day will be clear."
I believe i got my point across
The probability can be expressed in the form of percentages as well as fractions form.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
A local weather forecaster uses percentages to describe the chances of precipitation.
As we know, probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Let the chance of rain is 50% for tommorrow.
The probability for rain = 50%
We can write the above probability in the a form of fraction.
P = 50% = 50/100
P = 1/2
Thus, the probability can be expressed in the form of percentages as well as fractions form.

Answer:
See belowStep-by-step explanation:
Given equation:
3x² + 5x + 2 = 0Factorize it in steps:
3x² + 5x + 2 = 03x² + 3x + 2x + 2 = 03x(x + 1) + 2(x + 1) = 0(x + 1)(3x + 2) = 0The roots are:

Demetrius is training for the same 1-mile race.
Demetrius ran at a constant speed of 7.5 miles per hour.
Yosef's progress is shown by the graph.
Who finished the mile first?
Yosef finished the mile in 9 minutes.
Distance = 1 mile
Demetrius' speed = 7.5 miles per hour
Demetrius' time = Distance/speed
= 8 minutes
Demetrius finished the mile first by taking 1 minute less than Yosef's finishing time.
Answer:
Demetrius wins the race by 7.5 minutes.Step-by-step explanation:
We know that:
Demetrius = 7.5 miles = 60 minutesYosef = 1 mile = 9 minutesLet's see how much time Yosef take in 7.5 miles.
Solution:
Yosef speed = 1 mile = 9 minutes=> 7.5 miles = 9 x 7.5 minutes=> 7.5 miles = 67.5 minutes60 minutes < 67.5 minutesAfter working on this problem, we can conclude that Demetrius wins the race by 7.5 minutes.

Answer #2 for me , all you have to do is graph the function which is y = 1/2 x - 5 and i completed the table .
Answer/Step-by-step explanation:
The given function is linear. The curve will be a straight line.
Find two points. Plot them on a graph sheet. Join them with the help of a straight Line.
Given - y = 1/2 x - 5
Find the Y - intercept
At x=0;y=1/2(0)−5
(0,−5) is one of the points.
For the other point we would normally find the X-intercept.
If we did that with this equation we would create a fraction. It may be little difficult to fix that point. So, instead, assign a value to y so that you get a whole number as x-co-ordinate.
In our case we shall assign +1 as y-co-ordinate.
At y=1;1=1/2x−5
1/2x−5=1
1/2x=1+5=6
x=6×2=12
(12,1) is another point.
Plot the points
(0,−5) and (12,1)
Join them with a straight line. You get the curve.

What divisor is represented by the synthetic division below? A vertical line and horizontal line combine to make a L shape. There are two rows of entries within the shape. Row 1 has entries 2, 10, 1, 5. Row 2 has entries blank, negative 10, 0, negative 5. Entry negative 5 is on the outside to the left of the shape, and a third row of entries is outside and below the shape. Row 3 has entries 2, 0, 1, 0. –5 5 x 5 x – 5.
One of the ways of dividing polynomials is by synthetic division
The divisor of the synthetic division is x + 5
How to determine the divisor of the divisionFrom the question, we understand that:
Entry -5 is on the outside to the left of the shape
The entry represents the zero of the divisor.
Next, we set this entry to the variable (assume the variable is x)
So, we have:
[tex]x = -5[/tex]
Add 5 to both sides
[tex]x + 5= 0[/tex]
Hence, the divisor of the synthetic division is x + 5

Answer:
The constant of proportionality is 1/4.
Step-by-step explanation:
Keep in mind that the constant of proportionality can always be found by dividing any y value by any x value, as long as the values are in the same row. For example, in this table, the constant of proportionality would be 1/4, as, in the first row, the y value is 2 and the x value is 8, and 2/8 equals 1/4.

tell whether g=15 is a solution of 19-g=7
YES
NO
Answer:
NO
Step-by-step explanation:
19 - g = 7 ( subtract 19 from both sides )
- g = - 12 ( multiply both sides by - 1 )
g = 12 ← is the only solution
Answer:
No.
Step-by-step explanation:
To tell whether g = 15 is a solution, you substitute (replace) 15 in the equation.
Substitute 15 in for g:
[tex]19-15=7[/tex]
Solve:
[tex]4\neq 7[/tex]
15 isn't a solution to the equation.
The only solution valid is when g = 12.
Substitute 12 in for g:
[tex]19-12=7[/tex]
Solve:
[tex]7=7[/tex]
What was the median number of posts made?
Using it's concept, it is found that the median number of posts made was of 8.5.
What is the median of a data-set?The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
In this problem, the total number of observations is the sum of the frequencies, hence:
T = 1 + 0 + 3 + 1 + 2 + 1 + 1 + 2 + 3 + 5 + 9 = 28
Even number, hence the median is the mean between the 14th and the 15th elements, of the ordered set, hence:
M = (8 + 9)/2 = 8.5.
To remind, the ordered set is: {0, 1, 1, 1, ..., 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 10, 10, 10, 10, 10}
