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.

Evaluate the equation below.
p + 333 = 350
Answer:
17
Step-by-step explanation:
350-333 = 17
p = 17
Or...
Subtract 3 from both sides of the equation
p+333=350
+333−333=350−333
p = 17
Answer:
p=17
Step-by-step explanation:
p+333 = 350 (subtract 333 on both sides)
350-333 = 17
p = 17

Answer:
the 4th answer : a = 3 and b = sqrt(3)
Step-by-step explanation:
remember that i = sqrt(-1).
so, when you "take out" -1 of -3, you get 3.
sqrt(-3) = sqrt(3×-1) = sqrt(3)×sqrt(-1) = sqrt(3)i
Please help i struggle with algebra
Answer:
17
Step-by-step explanation:
multiply both sides of the equation by 8
k + 31 = 48
move the constant to the right-hand side and change its sign
k = 48 - 31
subtract the numbers
k = 17

x +y = y-m
what is m
Answer:
m = -x
Step-by-step explanation:
x +y = y-m
subtract y on both sides which will cancel them out, we are left with
x = -m
multiply both sides by -1 to get rid of the -m
x × -1 = -x, -m × -1 = m
final answer: m = -x
Let's solve

There are 8 cups of pasta in 22 servings. Write a proportion that gives the number x of cups of pasta in 3 servings.
one proportion is:
Answer:
Step-by-step explanation:
Cups: servings
8 : 22 :: x : 3
Product of means = product of extremes
22*x = 3*8
[tex]x = \dfrac{3*8}{22}=\dfrac{3*4}{11}=\dfrac{12}{11}=1\dfrac{1}{11}[/tex]
A person overcharges his bank account by spending the same amount of money each day. After five days of overcharging his bank account, he is $100.00 dollars in debt. Therefore, each day, his account balance changed by how much?
Answer:
20
Step-by-step explanation:
Why? because 100$ in 5 days is he spent the same much each day then it's 20 because 20 x 5=100
20 x 1=20
20 x 2=40
20 x 3=60
20 x 4=80
20 x 5=100
Lenore lives in a state where sales tax is 10%. This means you can find the total cost of an item, including tax, by using the expression c + 0.10c, where c is the pre-tax price of the item.
Use the expression to find the total cost of an item that has a pre-tax price of $84.00.
Function is
f(c)=c+0.10cPut 84.00$
[tex]\\ \tt\hookrightarrow 84.00+0.1(84.00)[/tex]
[tex]\\ \tt\hookrightarrow 84.00+8.4[/tex]

3х - 4y = 15
7x+y= 4
Substitution
Answer:
3x-4y=15
7x+y=4
Solve7x+y=4 for y:
7x+y=4
7x+y+−7x=4+−7x (Add -7x to both sides)
y=−7x+4
Step: Substitute −7x+4 for y in 3x−4y=15:
3x−4y=15
3x−4(−7x+4)=15
31x−16=15 (Simplify both sides of the equation)
31x−16+16=15+16 (Add 16 to both sides)
31x=31
(Divide both sides by 31)
x=1
Step: Substitute 1 for x in y=−7x+4:
y=−7x+4
y=(−7)(1)+4
y=−3(Simplify both sides of the equation)
Answer: x=1 and y=−3
find the equation of the line
Answer:
Y = 1/4x+2
Step-by-step explanation:
So to find the slope of the line you can use rise/run to do this you can pick two points and count how may squares is going up and how many is going to the left.
For this problem the two points can be (0,2) and (4,1) and if we count how many squares it goes up by we can see its 1 and if we count from (0,2) to (4,1) horizontally the space is 4
To find y-int it is just where the line crosses the y axis

What is 2.58333333333 as a fraction?
Answer:
2 583/1000
Step-by-step explanation:
Answer
To write 2.58333333333 as a fraction you have to write 2.58333333333 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
2.58333333333 = 2.58333333333/1 = 25.8333333333/10 = 258.333333333/100 = 2583.33333333/1000 = 25833.3333333/10000 = 258333.333333/100000 = 2583333.33333/1000000 = 25833333.3333/10000000 = 258333333.333/100000000 = 2583333333.33/1000000000 = 25833333333.3/10000000000 = 258333333333/100000000000
And finally we have:
2.58333333333 as a fraction equals 258333333333/100000000000
