Solve for x.
0.5x+78.2=287
Answer:
x =417.6
Step-by-step explanation:
0.5x+78.2=287
Subtract 78.2 from each side
0.5x+78.2-78.2=287-78.2
.5x =208.8
Divide each side by .5
.5x/.5 = 280.8/.5
x =417.6

If you put $5,000 in an investment that earns 8% interest compounded continuously, how many years, rounded to the second decimal, will take it until you have $8,303.00?
Answer:
6.34 years
Step-by-step explanation:
Given data
Principal P=$5,000
Rate r= 8%
Final amount A= $8,303.00
The expression for the time will be
t= ln(A/P)/r
substitute
t= ln(8,303.00/5000)/0.08
t= ln(1.6606)/0.08
t= 0.507/0.08
t= 6.3375
Hence the time is about 6.34 years
How can the manager use the data in the dot plot to improve the airline?
Answer:
The dot plot shows that most planes fly below the optimal cruising speed. This means that the airline isn’t being as efficient as it can be. So, the manager needs to have a discussion with the pilots to determine why they aren’t reaching the optimal cruising speed or check the planes to make sure everything is running at full capacity.

Chelsey wants to join a fitness club. The fitness club charges an initial membership fee of $55 and a monthly fee of $19.50. She has $250 to spend on a membership at the fitness club. Which equation represents the situation? If m is the number of months.
55 + 19.50m = 250
55m -19.50 = 250
55 - 19.50m = 250
55m +19.50 = 250

what is x+3=12 simplified?
Answer:
x = 9
Step-by-step explanation:
x + 3 = 12
subtracting both sides by 3
x + 3 - 3 = 12 - 3
x + 0 = 9
x = 9
Answer:
x = 9
Step-by-step explanation:
x + 3 = 12
x (+ 3 - 3) = 12 - 3
x = 9

4. Up until the last game, Sellina has made 75% of her free-throws. If she continues
to make her free-throws at this rate, what is the probability that she will make the
next two free-throws in the next game?
Answer:
0.5625 = 56.25% probability that she will make the next two free-throws in the next game.
Step-by-step explanation:
For each free throw, there are only two possible outcomes. Either Sellina makes it, or she misses. The probability of making a free throw is independent of any other free throw. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
75% of her free-throws.
This means that [tex]p = 0.75[/tex]
What is the probability that she will make the next two free-throws in the next game?
This is P(X = 2) when n = 2. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{2,2}.(0.75)^{2}.(0.25)^{0} = 0.5625[/tex]
0.5625 = 56.25% probability that she will make the next two free-throws in the next game.

2 Which table represents a function? X y X у 2 -3 -3 0 3 0 -2 1 4 -3 -3 2 2 1 2 3 (1) (3) х X у 1 2 AWNIK -4 1 2 1 NO 4. 1 5 4 6 (2) (4)
The only table that represents a function is the fourth option.
What is a function?
A function is a relation that maps elements from a set (domain) into elements of another set (range).
Such that each element from the domain can be mapped into only one element from the range.
In the table, the "x" values are from the domain, and the "y" values are from the range.
So, if you see a table with the same value of x being mapped into two different values of y, then that relation is not a function.
With that in mind, the only table that meets this property is table number 4.

For the remaining portion of the living room not covered by the new flooring, Michelle wants to paint the concrete. After carefully measuring the exposed concrete, she determines 6 square feet are already painted and the remaining unpainted area forms a square with side length x. The entire area of concrete, including the painted and unpainted portions, is a total of 31 square feet. Write an equation that could be used to find the unpainted square side length x
Answer:
[tex]x^2 + 6 = 31[/tex]
Step-by-step explanation:
Given
[tex]Painted = 6ft^2[/tex]
[tex]Total = 31ft^2[/tex]
Dimension of unpainted area:
[tex]Length = Width = x[/tex] --- Square
Required
Determine an expression to solve for x
First, calculate the area of the unpainted space;
[tex]Area = Length *Width[/tex]
[tex]Area = x*x[/tex]
[tex]Area = x^2[/tex]
The unpainted area, added to the painted area, equals the total area.
So, we have:
[tex]Area + Painted = Total[/tex]
[tex]x^2 + 6 = 31[/tex]
Hence, the expression is: [tex]x^2 + 6 = 31[/tex]

Mr. Howard planted a new garden. The garden is 15 feet long and 4 feet wide. What is the perimeter of mr. Howard's garden?
Answer: 38 feet
Step-by-step explanation:
Based on the dimensions of the garden, we can infer that it a rectangular garden because one side is longer than the other.
The perimeter of a rectangle is calculated as:
= (2 * length) + (2 * width)
= (2 * 15) + (2 * 4)
= 30 + 8
= 38 feet
