Answer:
Those ratios are not equivalent
Step-by-step explanation:
3:4 is not the same as 4:3 because 3:4 means 3 out of 4 but 4:3 means 4 out of 3 which means it is more than one while 3:4 is less than one
Ryan's annual salary is $54,000. A total of $15,340.80 will be deducted for taxes and health insurance. He will receive his paycheck monthly in 12 equal
installments. How much will he get paid with each paycheck?
Answer:3,221.6
Step-by-step explanation: if you divide 54,000 by 12, you get 4,500 which is the untaxted payment per month, then you must divide 15,340.80 by 12, which is 1,278.4, then you subtract that from 4,500 which ends up being 3,221.6

withdraw money from the account. How much money will be in the account after 4 years?
Answer:
$2,400
Step-by-step explanation:
First we need to find whatever that 5% is.
[tex]\frac{5}{100} \times \frac{2000}{1}[/tex]
Which gives us $100.
Now, we multiply the $100 by 4.
Which is $400.
Now, we add that to the $2,000.
Which gives us $2,400.

An American roulette wheel has 38 spaces, labeled using the numerals 1 through 36, 0, and 00. In a random spin of the wheel, what is the probability that the ball will land on 2?
This is because there's one space labeled "2" out of 38 spaces total.
This fraction is approximately equal to 1/38 = 0.0263 meaning there's roughly a 2.63% chance of landing on this space.
The probability is 0.0263 that the ball will land on 2 in a random spin of the wheel.
What is probability?The probability is defined as the possibility of an event is equal to the ratio of the number of outcomes and the total number of outcomes.
Assuming an unbiased wheel.
The probability of an event = number of favourable outcomes/ number of total outcomes.
The total number of outcomes is 38
The number of favourable outcomes is one because there's one space labeled "2" out of 38 spaces total.
The probability of an event = 1/38 = 0.0263
Hence, the probability is 0.0263 that the ball will land on 2 in a random spin of the wheel.

Answer:
x = 44.5 due to the Triangle Angle Sum Theorem
Step-by-step explanation:
This is the Triangular Angle Sum Theorem.
This rule states that every angle inside the triangle has to equal 180.
This is a solve for x situation
2x + x + x + 2 = 180
Add all the x's first
3x + x + 2 = 180
4x + 2 = 180
Now subtract 2 both sides
4x = 180 -2
4x = 178
Divide 178 by 4
x = 44.5
You could verify by plugging 44.5 into the x's
2(44.5) + 44.5 + 44.5 + 2 = 180
89 + 44.5 + 46.5 = 180
Answer:
x = 44.5
Step-by-step explanation:
2x + x + (x+2) = 180
4x + 2 = 180
4x = 178
x = 44.5

Answer:
6.1291 < 8.3 < 8.308 < 8.38
Step-by-step explanation:
Start by looking at the whole numbers.
6 < 8
Since the only whole numbers are 6 and 8, we can rule out that the smallest number, or with the least value, is 6.
Next, look at the tens place.
Since they are all 8.3--, we cannot find the next one until we look at the hundredths place.
Next, look at the hundredths place.
Keep in mind that 8.3 is the same as 8.300
There is 8.30 < 8.38 and 8.308 <8.380
Now we know the lowest value and the highest value! (6.1291 and 8.38)
Between the last two, let's figure out where they place
Look at the thousandths place.
8.300 < 8.308
Hence, the answer provided above!
6.1291 < 8.3 < 8.308 < 8.38
Hope this helps! :)

A coin is flipped 8 times. Find the probability of the event: Exactly 5 heads
a.0.625
b.0.03125
c.0.219
d.0.0039
Answer:
c. 0.219
Step-by-step explanation:
If the coin is fair, then the probability of flipping a head is 1/2 = 0.5
Therefore, we can model this as a binomial distribution:
X ~ B(n, p) where n is the number of events and p is the probability of success
Given:
n = 8p = 0.5X ~ B(8, 0.5)
Using a calculator:
P(X = 5) = 0.21875 = 0.219 (3 dp)
Using the formula:
[tex]\sf P(X=x)=\dfrac{n!}{(n-x)!x!}p^x(1-p)^{n-x}[/tex]
(where n is the number of events, x is the number of desired successes and p is the probability of success)
[tex]\sf \implies P(X=5)=\dfrac{8!}{(8-5)!5!}0.5^5(1-0.5)^{8-5}[/tex]
[tex]\sf \implies P(X=5)=\dfrac{8!}{3!5!}0.5^50.5^3[/tex]
[tex]\sf \implies P(X=5)=56 \cdot 0.5^8[/tex]
[tex]\sf \implies P(X=5)=56 \cdot \dfrac{1}{256}[/tex]
[tex]\sf \implies P(X=5)=\dfrac{7}{32}[/tex]
[tex]\sf \implies P(X=5)=0.21875[/tex]
A boat, which moves at 29 miles per hour in water without a current , goes 825 miles upstream and 825 miles back again in 58 hours. Find the speed of the current to the nearest the the place.
Answer:
4 mph
Step-by-step explanation:
Travel time is proportional to distance and inversely proportional to speed. If c represents the speed of the current in miles per hour, an equation for the total trip time is ...
825/(29 -c) +825/(29 +c) = 58 . . . . . . hours travel time
825(29 +c) +825(29 -c) = 58(29 -c)(29 +c)
58c² -928 = 0 . . . . . . . rearrange to standard form
58(c -4)(c +4) = 0 . . . . factor
Values of c that satisfy this equation are 4 and -4. For the purpose here, we'll choose the positive solution.
The speed of the current is 4 miles per hour.
