$6,000 dollars is invested in two different accounts earning 3% and 5% interest. at the end of one year, the two accounts earned $220 in interest. how much money was invested at 3%
Answers
The amount of money is 4000 was invested at 3%.
Let x be the amount of money invested at 3%.
Then, the amount of money invested at 5% is 6000 - x.
The interest earned on the amount invested at 3% is 0.03x.
The interest earned on the amount invested at 5% is 0.05(6000 - x) = 300 - 0.05x.
The total interest earned is given as $220.
So, we can write the equation:
0.03x + (300 - 0.05x) = 220
Simplifying and solving for x, we get:
0.03x + 300 - 0.05x = 220
-0.02x + 300 = 220
-0.02x = -80
x = 4000
Therefore, $4000 was invested at 3%.

Suppose Manuela flips a coin three times. What is the theoretical probability of flipping tails at least two times? Express your answer as a fraction in simplest form.
Answers
The probability of flipping tails at least two times in three flips is 1/2.
When flipping a coin, there are two possible outcomes: heads or tails. Each flip is independent of the previous flips, so the probability of getting tails on any given flip is always 1/2 (assuming the coin is fair).
To find the theoretical probability of flipping tails at least two times in three flips, we can use the binomial probability formula:
P(x ≥ k) = 1 - P(x < k)
where P(x < k) is the probability of getting tails fewer than k times in three flips.
To find P(x < k), we can add up the probabilities of getting tails 0 times and getting tails 1 time:
P(x < 2) = P(0 tails) + P(1 tail)
P(0 tails) = (1/2)⁰ x (1/2)³ = 1/8
P(1 tail) = 3 x (1/2) (1/2)² = 3/8 (since there are three ways to get exactly one tail: TTH, THT, HTT)
P(x < 2) = 1/8 + 3/8 = 1/2
Therefore, the probability of flipping tails at least two times in three flips is:
P(x ≥ 2) = 1 - P(x < 2) = 1 - 1/2 = 1/2
So the theoretical probability of flipping tails at least two times in three flips is 1/2 or 0.5 as a decimal.

Olga Semargl's medical care bills for a recent illness were $4,620. Her major medical policy did not
cover $312 of the bill. Olga's policy had a coinsurance feature that paid 80% of all covered expenses
over a $500 deductible. What was the amount paid by the major medical policy?
Answers
The amount paid by the major medical policy is $3,046.40.
First, we need to calculate the covered expenses before the coinsurance feature comes into play. Since Olga's major medical policy did not cover $312 of the bill, the covered expenses will be:
Covered expenses = Total bill - Amount not covered
Covered expenses = $4,620 - $312
Covered expenses = $4,308
Next, we need to calculate the amount of the covered expenses that is subject to the coinsurance feature. Since Olga's policy has a $500 deductible, the covered expenses subject to coinsurance will be:
Covered expenses subject to coinsurance = Covered expenses - Deductible
Covered expenses subject to coinsurance = $4,308 - $500
Covered expenses subject to coinsurance = $3,808
The coinsurance feature pays 80% of the covered expenses subject to coinsurance, so the amount paid by the major medical policy will be:
Amount paid = Coinsurance rate x Covered expenses subject to coinsurance
Amount paid = 0.8 x $3,808
Amount paid = $3,046.40
Therefore, the amount paid by the major medical policy is $3,046.40.

When a point is reflected over the x-axis, its y-coordinate changes sign.
In this case, the point P has coordinates (4,3).
To reflect it over the line x=3, we need to keep its x-coordinate the same and change its y-coordinate to its opposite.
So, the x-coordinate of the reflected point will still be 4, but the y-coordinate will become -3.

A ladder measures 6 feet. If the top of the ladder is placed 4 feet up on a wall, how many feet from the base of the wall is the bottom of the ladder?
Answers
In this case, the ladder, the wall, and the ground form a right triangle, with the ladder being the hypotenuse. Let x be the distance from the base of the wall to the bottom of the ladder. Then we have:
x^2 + 4^2 = 6^2
Simplifying the equation:
x^2 + 16 = 36
Subtracting 16 from both sides:
x^2 = 20
Taking the square root of both sides:
x = sqrt(20)
Simplifying:
x = 2sqrt(5)

Two households are saving money each month to go towards the shared costs of a vacation trip. One household has $700 saved and will continue saving $400 each month. The other household has $1,000 saved and will continue saving $300 each month.
Use the system of equations, where y represents total saved and x represents number of months, to answer the question.
y = 400x + 700
y = 300x + 1,000
At what point would the two lines intersect if graphed?
Answers
The two lines will intersect after 3 months.
How to explain the equationWe can set the two expressions for y equal to each other:
400x + 700 = 300x + 1,000
100x + 700 = 1,000
100x = 300
x = 3
So the two lines will intersect after 3 months. In this case, to find the corresponding value of y, we can substitute x = 3 into either of the equations:
y = 400x + 700
y = 400(3) + 700
y = 1,500
Therefore, the two lines will intersect after 3 months, at a point with coordinates (3, 1,500).

(Can you also just make an equation out of this for me?)
Answers
The system of equations are t = 22.28 years , number of nickles and dimes are solved
Given data ,
a)
Let the number of years be represented as t
For truck A, the total cost (including the initial cost and average yearly repair cost) after "t" years can be represented as:
Total cost for truck A = 20345 + 1230t
For truck B, the total cost (including the initial cost and average yearly repair cost) after "t" years can be represented as:
Total cost for truck B = 16000 + 1425t
when the total costs are equal , we get
20345 + 1230t = 16000 + 1425t
On simplifying , we get
195t = 4,345
t = 22.28 years
b)
Let the number of nickels be n and number of dimes be d
The total value of nickels is 0.05n (since the value of one nickel is $0.05) and the total value of dimes is 0.10d (since the value of one dime is $0.10)
The total value of the coins = $ 2.05
And , the total number of coins = 56
0.05n + 0.10d = 2.05

to take a nice vacation each summer. They are receiving a large refund, rather

Answers
Receiving a large tax refund is problematic because it means overpaying taxes and missing out on the opportunity to use that money throughout the year for paying down debt, building an emergency fund, or investing.
We have,
While receiving a large tax refund each year may seem like a positive thing, it actually means that Mia and Allen are overpaying their taxes throughout the year.
This means that they are essentially giving the government an interest-free loan by allowing them to hold onto their money instead of having it available to them throughout the year to use for things like paying down debt or investing in their future.
By overpaying their taxes,
Mia and Allen are essentially missing out on the opportunity to use their money in ways that could benefit them in the long run.
Additionally, the large tax refund they receive each year may create a sense of false security, leading them to believe that they are in a better financial situation than they actually are.
Rather than receiving a large tax refund each year, it may be more beneficial for Mia and Allen to adjust their tax withholdings so that they are receiving more money in each paycheck.
This way, they can use the extra money to pay down debt, build up their emergency fund, or invest in their future, rather than giving the government an interest-free loan.

The measure of the angle m∠3 of the triangle is m∠3 = 150°
Given data ,
Let the triangle be represented as ΔABC
Now , the measures of the angles are
m∠1 = ( 3x + 12 )°
m∠2 = ( 3x + 18 )°
m∠3 = ( 7x + 10 )°
m∠3 = 180° - ( m∠1 + m∠2 )
Now , for a triangle , the total angles = 180°
So , m∠1 + m∠2 = m∠3
On simplifying , we get
( 3x + 12 ) + ( 3x + 18 ) = ( 7x + 10 )
6x + 30 = 7x + 10

Alternatively, we can use the fact that reflecting a point over a line is equivalent to reflecting the coordinates of the point across the line. In this case, we are reflecting over the line y = -2, so we can simply negate the y-coordinate of each point to find its reflection.
Using this method, the reflected vertices are:
N'(-5, -4)
M'(-2, -3)
O'(-3, -1)
′(Therefore, the correct answer is option D: N−5, −6), M′(−2, −5), O′(−3,-7)
